2 questions about Ubuntu...

My first question is, how do I set up a dial-up connection on Ubuntu 8.10 Intrepid Ibex? I've tried all the ways on this site, none of which worked: http://www.ubuntugeek.com/setting-up-dial-up-connection-in-ubuntu.html. (The main problem is, there is no System > Administration > Networking option...)

The second question is, how do I get that GRUB thing to boot into Windows by default?

Thanks

144.138.21.27 (talk) 00:32, 15 April 2009 (UTC)Will

I have an answer to the second question. When you see the GRUB menu, you need to count the number of operating systems that are listed. The first OS is 0, the second one is 1, the third is 2, etc. Keep counting until you get to Windows, and stop. Remember this number. Boot into Ubuntu and open /boot/grub/menu.lst with the text editor of your choice. Gedit will do the trick. Somewhere in there, there should be a line that says default 0. Change 0 to the number of the Windows entry. Then, run sudo update-grub. Xenon54 (talk) 01:12, 15 April 2009 (UTC)

Hey Xenon54, while that might work, I strongly suggest an easier way: just install StartUp Manager ( http://web.telia.com/~u88005282/sum/index.html ). it is available at the ubuntu repositories SF007 (talk) 05:41, 15 April 2009 (UTC)

Thanks for solving that second one, works a treat now :) If only I could say the same for the dial-up, I've re-tried everything on the above page, to no avail... I think if I can somehow get the old System > Administrator > Networking dialogue back, or that GnomePPP installer working, I should be able to sort something out from there. Thanks! —Preceding unsigned comment added by 144.138.21.148 (talk) 08:20, 15 April 2009 (UTC)

That article is over 2 years old, so it's a bit inaccurate. The System->Admin->Networking dialogue was provided by NetworkAdmin, which they've apparently been trying to phase out in favor of NetworkManager, which... well... I don't care for it much, but it mostly works. However, it doesn't seem to do dial-up, and I'm frankly surprised that they didn't include dial-up configuration in 8.10 by default. Anyway, if you follow this guide, which seems up-to-date, you'll need to install either the gnome-network-admin or gnome-ppp package. Then you can follow the steps they outline there, and assuming there are drivers for your modem, it should work. Good luck! Indeterminate (talk) 10:33, 15 April 2009 (UTC)

I tried the link in that article, and it siad to try a wvdial thing, and I ended up finding out I have no driver for the modem installed... how can I fix this? —Preceding unsigned comment added by 144.138.21.129 (talk) 02:19, 16 April 2009 (UTC)

I've just realised, there is a "Network Configuration" option in System > Preferences, but it says never to dial the connection... as well as that, it should ask me for the number to dial, but it doesn't, so how can I get this dialogue box to work for dial-up? 144.138.21.36 (talk) 09:01, 16 April 2009 (UTC)

Ticketmaster PDF file - wrong characters printed

This question is mostly out of curiosity because I have already printed a fresh, correct copy of my document. So, I got a PDF file from Ticketmaster containing event tickets, along with 2/3rds page of advertisements (which I gladly paid $2.50 for the privilege of printing on my own printer with my toner... I guess that's another story...). The images printed fine, but everything that was text, like the venue name and event, as well as the date and time, printed what appeared to be random character strings. I didn't notice at first, but someone pointed out to me that the line "SAT APR 18 2009 3:30PM" was printed as "TBU!BQS!29!311:!4;41QN" . OK, so I looked at 311: and thought, "Isn't that 2009, but incremented by one?" Why yes, it is.

So, the real question is not WHAT happened, but WHY? Freedomlinux (talk) 00:52, 15 April 2009 (UTC)

I've had the same problem, try the "print as image" option under advanced options. Sealedinskin (talk) 08:57, 15 April 2009 (UTC)

Yeah, all those characters that were printed are just the correct Ascii value + 1. Interesting. No idea why. Indeterminate (talk) 10:21, 15 April 2009 (UTC)

Formating problem

I think I got some kind of virus on my PC. It doesn't let me do a system restore (it won't come up) and some normal files (mp3 etc) are also not opening. I tried to format the drive so I can clean up the thing. Now the problem is, when I tried to format it when booting using the windows XP CD, it does not boot from the CD but starts as normal. When I tried to go to the boot menu at startup, the keyboard doesn't work there (at the boot menu) so I can't select anything. Is there any way to format this drive? Any help would be appreciated202.124.190.174 (talk) 05:32, 15 April 2009 (UTC)

Can you get into BIOS (usually, there is a message at the very start of bootup saying something like Press F2 for BIOS). If so, set the CD to be the primary boot device, not the hard drive. -- kainaw™ 06:05, 15 April 2009 (UTC)

Are you using a USB keyboard? Try a PS/2 one.F (talk) 09:45, 15 April 2009 (UTC)

@Kainaw: As I said, when I go there my keyboard is disabled. So I can go there but can't change anything once I'm there. I should also add that the keyboard works fine everywhere else, but is disabled only when I access those BIOS menus. 202.124.190.45 (talk) 13:04, 15 April 2009 (UTC)

To be clear... The "boot menu" which you mentioned is a menu that comes up AFTER the BIOS loading sequence that usually lists the devices you have with number in front of them. You press the number you want to boot. The "BIOS menu" comes before the boot menu. You usually get to it using a keypress (ie: F8). It has a lot of settings about drives, graphics, etc... It is difficult to know if you can't access one, the other, both... Another option is to reset BIOS completely. There will be a jumper on your motherboard - two pins that stick up for no apparent reason. Usually, there is a little metal clip wrapping in black plastic to look like a tiny black plastic rectangle - it will be sitting on one of the pins, but not the other. Pull it off and place it on both pins for a few seconds. Then, return it to the way it was. Your BIOS will be reset. Of course, you have to ensure you are using the BIOS reset jumper and not one of many other possible jumpers on the motherboard. That usually means that you have to identify the make/model of your motherboard, go online to get the manual, and then read the manual to figure out which jumper is the BIOS reset. -- kainaw™ 13:12, 15 April 2009 (UTC)

Try a PS/2 keyboard instead of a USB keyboard. Also if the first BIOS screen says "Press F2 for boot options" or "Press F2 for configuration" or whatever, hit F2 repeatedly during this screen, not just once - some BIOSes I've worked with have a pretty narrow window of when you can hit the key.

archive calendar in WordPress

For my blog (now seven years old), I'd like to have an archive calendar page like many webcomics have. Anybody know of such a thing done in WordPress? I don't grok the SQL anywhere near well enough to write it myself. —Tamfang (talk) 06:39, 15 April 2009 (UTC)

Don't worry, they're one step ahead of you. :) This guide [1] looks pretty easy to follow. They have some links at the bottom to other archive options if that isn't specifically what you want. Indeterminate (talk) 10:15, 15 April 2009 (UTC)

Thanks but I don't see anything there that even vaguely resembles what I have in mind (see the Sinfest link above): a series of monthly calendars with a link for each day that has >0 posts. (There is a function to show such a calendar for the current month.) This would work too. —Tamfang (talk) 18:45, 15 April 2009 (UTC)

Unformat

How can you unformat a drive that has been formatted? 58.165.25.29 (talk) 11:45, 15 April 2009 (UTC)

Do you want to restore a particular file? Then you can try some of the software available to "undelete" files (I believe that a simple "format" command in general will not destroy any data on the disk). I do not know of any simple way of simply "undoing" the command. --Andreas Rejbrand (talk) 12:54, 15 April 2009 (UTC)

But, whatever you do – do not write anything to the disk, for doing so may overwrite the data you want to restore. If you need to install a file recovery software, do so on another disk! --Andreas Rejbrand (talk) 13:04, 15 April 2009 (UTC)

See our article Disk formatting. As Andreas Rejbrand stated, your best bet is probably to try using undeletion software; I don't know of any way to undo a disk format. See Undeletion and Data recovery. Tempshill (talk) 16:34, 15 April 2009 (UTC)

Try testdisk. --wj32 ^t/c 02:24, 16 April 2009 (UTC)

DVD Decoder Location

Resolved

where is CLVSD.AX located in relation to my system? I LEGALLY PURCHASED this decoder and want to use it on my new computer (NOT IN VIOLATION OF EULA BTW it says for use on ONE computer so if i delete it off the old one i'm ok) but i can't seem to find the decoder. Where would it be?  Buffered Input Output 13:29, 15 April 2009 (UTC)

I googled CLVSD.AX and the first entry is how to install and uninstall AX files. Is there a reason you didn't just use the uninstaller and then use the installer on the new system? Tempshill (talk) 16:45, 15 April 2009 (UTC)

Sorry for wasting time...i resolved it on my own (after an e-mail to CyberLink later)  Buffered Input Output 22:21, 15 April 2009 (UTC)

Question

Explain ways to protect your computer against viruses and trojan horse programs. —Preceding unsigned comment added by 68.51.212.48 (talk) 16:29, 15 April 2009 (UTC)

See our article List of antivirus software, and for an explanation, see Antivirus software. Also, you should normally set up 2 accounts on your computer: one account with "administrator rights", which you use only to install software that comes from a trusted source; and one "user account" with no administrator rights, which you should use to surf the web, use e-mail, etc. This will make it harder for a trojan horse or virus to infect the system. Comparison of privilege authorization features talks a little about this principle, though it's full of jargon. Tempshill (talk) 16:45, 15 April 2009 (UTC)

Blender's game engine

What are the shortcomings of Game Blender? Can you create a multiplayer game with it? Can you create a game for any platform? Can you create an online game (like a Flash game)? Can you create a 3D online game? 80.58.205.37 (talk) 17:00, 15 April 2009 (UTC)

You can do all that except no browser plugin will run your game so no online game and "any platform" is a bit vague (it supports linux/windows afaik). It's possible to use python to script your game, so only the sky is limiting if you can be bothered to write some (eg networking) code of your own. Of course it can then be questioned if Blender scales for such large projects but let's not get into that. --194.197.235.70 (talk) 18:38, 15 April 2009 (UTC)

Linux/Xorg rich input

Is there an easy way to have a context sensitive keyboard layout, ie if the previous key typed was an vocal some button would be 'r' but after consonant it would be 'a'? --194.197.235.70 (talk) 18:52, 15 April 2009 (UTC)

Just to clarify what you mean. Say on a normal layout you would press 'Q' to have that letter appear on your screen. This would normally go for any letter that is on your keyboard. The layout you are asking about would do this; Pressing 'Q' would only type out 'Q' should the previous letter have been 'A', 'E', 'I', 'O' or 'U', maybe 'Y'. If i am correct this would be a very complex layout that would take some time to master. Only to provide little advances over the current QWERT layout. Depending on the layout it would be difficult to type out words such as 'Lie' and 'Lye', Or 'Bite' and 'Byte', How about the words 'Fart' and 'Fat'? There are a lot of words, maybe even sentences, out there that would be very hard to type out with your proposed layout... at least for the English language. – Elliott(Talk|Cont)  19:50, 15 April 2009 (UTC)

I realize that i have not answered your question. To the best of my Knowledge i dont know how you would define 'easy'. To an experienced programmer using Ubuntu, i supose this task would be easy. To a native of a lost tribe in Inda who has never seen a comoputer this would be a very hard task. The only way i could think of doing this task in away that would not matter what OS you used would be to do it in Flash. But it would take me weeks if nto months to achive this task. – Elliott(Talk|Cont)  19:55, 15 April 2009 (UTC)

Yes you understood correctly. Easy == existing. I use dvorak myself so I must say that even if the speed improvement to qwerty isn't huge, the "feel" of typing is more comfortable. Having layouts alternating would have better home row usage if the layouts are designed with some statistics of target languages in mind. Maybe more than ~200wpm is excess for anything but copying texts and even that's a bit obsolete nowadays, but hey we do what we must because we can. --194.197.235.70 (talk) 20:46, 15 April 2009 (UTC)

Your best bet is to look in to this keyboard.– Elliott(Talk|Cont)  20:55, 15 April 2009 (UTC)

You might also be interested in chorded keyboard. --Sean 21:34, 15 April 2009 (UTC)

On Windows XP, there is an utility that allows you to define your own keyboard layout (which you can then load like any other layout) - I'll assume something similar exists for Linux. By mapping "dead keys" you can have combinations like that on the Norwegian keyboard layout - for example, if I press the ¨ key on my keyboard, nothing happens. If I press space afterwards, I get just the dots (¨), if I press "o" afterwards I get ö. This is logical to people but of course what the computer does is just defining the ¨ key as an extra "shift-type" key, and conditioning the response of the next key on this. (If I want to type ¨ I have to press ¨ followed by a space). Now, similar things can be set up by the keyboard editor mentioned and you can of course have any combination you want - I think. The only disadvantage to the way I understand your request is that after pressing the first button nothing would happen until you press the next - to follow the example above, if you press A nothing will happen, then when you press Q you will get AQ. If you press Q directly you will get Z. That should be feasible. To press only A would then require two keystrokes, A and, say, space. This probably makes it not good enough for you but if you use this to create something, let me know, I'd be curious. Jørgen (talk) 23:31, 15 April 2009 (UTC)

OS - what's the point?

So far as I can tell, no operating system is different from any other. I don't see how I'd be doing anything differently if I was using Windows 95 right now instead of Vista. I used a Mac once (never again...two mouse buttons, plskthnx), and it didn't seem much different either, though I will admit I'm unfamiliar with anything non-Windows.

I use my computer seven hours a day.

Er...what are the differences between OS's? To me? Now that I come to think about it, this same question applies to internet browsers, too... =\ Vimescarrot (talk) 19:15, 15 April 2009 (UTC)

Perhaps I should clarify slightly; I use my copmuter for internet gaming and finding out new stuff. Oh, and watching videos. That's about it. —Preceding unsigned comment added by Vimescarrot (talk • contribs) 19:21, 15 April 2009 (UTC)

I would say that the graphical user interface (GUI) in Windows Vista is much more appealing than the GUI in Windows 95, but I believe that this argument is not very convincing to you. A more important thing is system stability and security. If one single application crashes in Windows 95, it is likely that the entire system will become unstable and unresponsive – likely, you have to perform a "hard" reboot (power cord out). In Windows Vista, this is very unlikely. Also, I have a lot of important data on my PC, and I do not want any other member of the family to be able to damage this data. In Windows Vista, they can't do that. In Windows 95, on the other hand, there is no protection at all (the password is just there for aesthetic reasons) – to access the data of another user, you only have to open the C:\WINDOWS\Profiles\<User Name>\ folder. Also, most new hardware (e.g. printers) will not work on Windows 95, because the system is too old. --Andreas Rejbrand (talk) 19:22, 15 April 2009 (UTC)

Stability. Check. Aesthetics. Check. Security. Check. This alone takes up the kajillion million rams that Vista requires? (Genuine question, I have no idea if it would or not) Vimescarrot (talk) 19:25, 15 April 2009 (UTC)

Yes, this is why vista failed as an operation system, And why windows 7 is coming out. But you seemed to have left out one type of operation systems; Linux. Linux is a unix OS, as is Mac. I know there is one thing that you can do in Mac and Linux that you cant in windows. And that is use Aircrack-ng to it's fullest. – Elliott(Talk|Cont)  19:35, 15 April 2009 (UTC)

Vista failed because it's superior? I didn't "leave them out"; I stated I didn't know them, you're more than welcome to comment on them. And I didn't think I'd have to point out that I don't know what Air-Cracks are. Vimescarrot (talk) 19:41, 15 April 2009 (UTC)

Vista failed because it was a memory hog. As for windows, there are some restrictions that disallow you to mess with the operating system. For instance you can access the Registry useing regedit, But your dont have access the the files that regedit uses. Have you ever tried to delete a file that is being used by a program? Windows wont let you. Linux will. Weather this is a good or bad thing really depends on the program (Virus? Excel?) and the file. From what i know (and i could be wrong) windows does now allow direct hardware controll. Now this is inportatnd to advanced users but not the someone who jsut uses the computer to surf the web and play games (as i do). Were as linux does allow direct hardware control. I hope this helped in some way. If you are intrested in the differences i'd this suggest link. —Preceding unsigned comment added by E smith2000 (talk • contribs) 20:08, 15 April 2009 (UTC)

The reasons Vista failed are IMHO too complicated and too widely debated to be summed up in to one simple sentence Nil Einne (talk) 14:28, 18 April 2009 (UTC)

Directionality of restrict

The restrict keyword in C99 is said to prohibit (for optimization) aliasing among pointers. It's pretty clear what this means when you have two restricted pointers; you're promising that they're unaliased (or else that you only read from them, in which case you needn't mark them with restrict in the first place). However, how they interact with normal pointers is less clear — even in the C99 standard draft that I have, I don't confidently understand the implications of the word "access". So: does the following code (compiled with or without RESTRICT_WRITE defined) violate the restrict rules if f() returns the same pointer twice?

int *f(void),g(void);
int h(void) {
  int *restrict p=f(),*q=f();
#ifdef RESTRICT_WRITE
  *q=g(); return *p; /* no write through p is visible via q */
#else
  *p=g(); return *q; /* no read through p depends on q */
#endif
}

In each case, one can argue that because q is unrestricted, it can do whatever it wants, and p must deal with it (and be less-well optimized). But one can also argue that p is restricted and that any use of q is automatically a mistake. --Tardis (talk) 19:36, 15 April 2009 (UTC)

A useful rule of thumb is that the compiler is allowed, for alias-analysis purposes, to pretend that any initialization or assignment to a restrict-qualified variable has a right hand side of malloc(something). In your code the compiler is allowed to pretend that the first call to f is a call to malloc; thus it's unsafe whether or not RESTRICT_WRITE is defined. -- BenRG (talk) 21:02, 15 April 2009 (UTC)

linux boot problem

when i boot my linux fedora laptop up i get three fedora 10 options from grub, know which ever option i choose i get this message:

ata2.00 ACPI cmd 00/00:00:00:00:00:b0 failed Emask=0x04 Stat=0x00 Err 0x01
ata2.00 ACPI cmd 00/00:00:00:00:00:b0 failed Emask=0x04 Stat=0x00 Err 0x01
ata2.00 revaildation error Errmo=-5

then some loading message that flashes before i can read it

now for the first two fedora boot options after this message i get the fedora loading bars and then the computer freezes with a flashing underscore in to the top left corner, but the third fedora boot option works and i can boot normally

googling round some people seem to say its a loose cable though i opened up my laptop and tried pushing the cable back in, no luck

some people seem to think its a problem with grub and they suggested :

$ cd /boot/grub
$ sudo cp menu.lst menu.lst.backup
(Type your own password when asked and go on.)
$ sudo vi menu.lst
-> You enter in vi editor to apply changes in the file menu.lst
-> Move forward until the first line begining with "kernel" (without any #)
-> Type i to begin inserting text
-> Delete "quiet splash" at the end of the line and replace it by "irqpoll all_generic_ide" as steph33560 said
-> Press Echap to finish insert mode
-> Type :wq and Enter to save and exit.

it threw up alot of text but it didnt stop the boot freezing problem

After some googling i think you might have a filing hard drive in your laptop. test this by trying to use a live CD. If the live CD works without any problems then you either do have a failing hard drive or your OS is bad. {i think}– Elliott(Talk|Cont)  21:42, 15 April 2009 (UTC)

Browser Crash

OK. This is my first time asking a question here, after several months of referring people here from the help desk. Anyways, lately my Firefox browser has been crashing. I'm running 3.0.8 on Mac OSX (10.5.6). This only seems to happen when I'm trying to view some Flash content (but not all Flash content). For example, Zero Punctuation. It starts to load, but then hangs. It also happens when I try to play some flash games. I've checked to make sure that I'm running Flash 10 and can't figure out what's going on. Does anyone have any tips? TNXMan 22:06, 15 April 2009 (UTC)

I am not really sure what is wrong with your browser but i'd suggest you try removing all your cookies, cache, Offline website data and maybe even your browsing history. From firefox you can do this by holding down ctrl+shift then hitting Del (at least you can from Ubuntu and windows XP). Also try removing your flash player and re-installing it. Do these flash videos work in a different internet browser? – Elliott(Talk|Cont)  22:14, 15 April 2009 (UTC)

Hmm, clearing my cache worked. I don't why I didn't think of that first. :( Anyways, thanks Elliott! TNXMan 22:25, 15 April 2009 (UTC)

Video issues

Resolved

My Nvidia GeForce FX 5200 Ultra card (an older card) is having problems. When i play Halo on this card, odd, small, flickering boxes appear on certain texture maps. Do i have a driver issue? or is the card dying?  Buffered Input Output 22:20, 15 April 2009 (UTC)

It might be that the card is overheating which could be because of dust build up within the case clogging fans/airflow. The easiest way to test is to run it with the side of the case off and see if you have the same problem. ZX81 ^talk 23:33, 15 April 2009 (UTC)

Nope, still there. Although i turned off some options in the Nvidia control panel and SOME of the boxes went away, but not all of them. I'll try to clean out the fan on the card; it looked pretty dusty.  Buffered Input Output 12:54, 16 April 2009 (UTC)

Still there after cleaning the card and reseating it AND reinstalling it. But i tried Star Wars Republic Commando and no boxes at all. I changed a supposedly relevant setting in the Nvidia control panel (conformant texture clamp) and the boxes still appear IN HALO ONLY!!! WTF???  Buffered Input Output 16:30, 17 April 2009 (UTC)

This is just a guess and may be completely wrong, but possibly your Halo installation is corrupted or at the very least perhaps some of the texture maps are damaged. I don't know how much hassle it is to reinstall the game (or where the save game files are stored), but it's probably worth a try. You could also try lowering the resolution/graphics settings to their minimum and seeing if the problem is still there (and then work out what setting causes the problem). ZX81 ^talk 18:25, 17 April 2009 (UTC)

It's the card. eVGA (the manufacturer) says the card was prone to overheating and are sending me a new one with a better fan. It should arrive soon. Thanks!  Buffered Input Output 16:03, 20 April 2009 (UTC)

An instant messaging client for the CLI and icons in Awesome

I have two questions:

• Is there an (open source) IM client for Linux you can use with the command line interface (a bit like rTorrent only for IM). I just started messing around with Awesome and both Pidgin and Emesene look pretty bad. (amazing coincidence, while looking for a picture for question 2 I found a screenshot of Awesome using what 'seems' to be an IM client)
• This one is also related to Awesome, how come the theme looks so ugly? Like Firefox, the buttons to go back and forward look ugly and old fashioned and so does the 'stop' button. The general theme is also rather ugly, some light-brownish gray compared to the the default Firefox in Ubuntu. Is this because I'm using the wrong theme? How do I change it? --BiT (talk) 22:22, 15 April 2009 (UTC)

Paper Animation software

I am looking forward to a career in animation, but don't know where to start in terms of software. I don't want to use a completely paperless animation suite because I won't get the results I want. I want to draw out the scenes and characters, scan them onto computers, and then put it all together. What software can I use to do this? I will use multiple suites and programs. Mac OS X is preferred. Please give suggestions and thanks in advance. --Randoman412 (talk) 23:21, 15 April 2009 (UTC)

In my experience i have come to like Flash, Some-what easy program to use, you can use it as a glorified flip book. Or if you want to get really advanced you can use it for some (limited) 3d animation. But if all your looking for is to scan photos in and throw them together then feel free to try Adobe Flash. – Elliott(Talk|Cont)  23:29, 15 April 2009 (UTC)

Autodesk Maya is the usual piece of animation software. Not sure about the use of paper with it, though. Tempshill (talk) 06:04, 16 April 2009 (UTC)

For very simple animation, you could simply scan each drawing as a .gif and edit into a single multi-frame gif using a raster graphics editor. Check for the features you need in the comparison of raster graphics editors or just try GIMP. Certes (talk) 16:21, 16 April 2009 (UTC)

You can certainly use Maya to do that - but it costs over a thousand bucks and it's distinctly overkill. You can make movies from still frames with any number of $0 OpenSourced software packages. (I use mplayer/mencoder because I like command-line tools - but there are any number of alternatives). However, I've gotta say that I'm entirely skeptical of your ability to make a career with paper animation...you're going to need to know packages like Maya like the back of your hand and adapt your animation style to the digital world - like it or not - that's where the work is.

XP and Vista icon Flickering when shutting down

While in the process of shutting down, a desktop icon usually flickers a few times before the computer shuts down. Why does this happen and how does the computer determine which icon to flicker? Acceptable (talk) 02:36, 16 April 2009 (UTC)

The flickering is because as Windows shuts down it will keep changing the active window between each application as it closes it down and the desktop. Everytime the focus shifts back to the desktop it highlights the last icon you were on and when it goes to shut down the next application it will change the focus from the and unhighlighting the icon in the process. Because of this you get that flicker effect you're describing. Hope that helps to explain! ZX81 ^talk

To add on to that, a typical Windows system has at least 3-4 'hidden'/invisible active windows as programs shut down. My favorite has been a Microsoft 'should not see this' shutdown task that hung and displayed an 'End Process' prompt. Washii (talk) 02:29, 19 April 2009 (UTC)

Windows Vista Home Premium SP1 Trial

Anyone know where I can download a Windows Vista Home Premium 32-bit SP1 trial version --Melab±1 ☎ 03:30, 16 April 2009 (UTC)

Although an unactivated version of Vista (any edition) will effectively function as a "trial" for 30 days, as far as I know Microsoft don't offer it as a download. The only download versions they do offer are the versions on MSDN or Technet (I've just checked and Home Premium is available on both), but you'd need a current subscription to either of those services to be able to access the downloads.

Window (not screen) video capture

I think that a problem I'm having with a piece of software could be best described/illustrated to its support desk if I could capture 20-30 seconds of pseudo- (or maybe real) video of only its own window, not the whole screen.

Video Card problem

I was running a CHKDSK on a hard drive and I needed to use the monitor on another computer so I swapped the cable out.

When I plugged it back in I got no signal out. I then restarted (probably interrupting the CHKDSK). Still couldn't get signal to the monitor (even the BIOS screens).

I put the video card (X1950XT) in other computer, and it works fine.

I put another video card (HD3400) into the computer and I see the BIOS screens but when it boots Windows (XP and 7) the monitor says "out of range". I can boot Windows in safe mode. I think this may be a separate problem to the one with the X1950XT...

Thanks in advance --130.194.165.125 (talk) 06:54, 16 April 2009 (UTC)

Try uninstalling the X1950XT and reinstalling it. And by uninstalling i mean going into device manager and delete it from the system. Then reinstall the drivers and the card and try again. Hopefully, this helps.  ;)  Buffered Input Output 12:58, 16 April 2009 (UTC)

How to paste into Word without the font changing?

Hi there, everyone:

I've been using Word for as long as I can remember, but there's one thing that has always annoyed me that I haven't been able to solve: Using Word 2002, I have set a default font, but when I paste from other resources, it nearly always changes all Serif Fonts to Times New Roman and all Sans serif fonts to Ariel - neither of which is my default. Is there any way to avoid the irritating need to change the font back every time I paste something?

All the best --134.151.34.100 (talk) 14:31, 16 April 2009 (UTC)

I'm not sure about Word 2002, but in 2003, when you paste an icon representing the clipboard will pop-up. Click the icon and a menu will appear. Click Match Destination Formatting or Keep Text Only. Another way is to paste the text into a text editor (such as Notepad). This will lose the formatting. Then copy and paste the text from Notepad into Word.

Web-based game programming (not flash)

I am interested in developing gadgets (think widgets) for igoogle and similar sites, which use the common web stuff: html, css, javascript. Does anyone know of a good resource (tutorials, forum) geared toward game programming in javascript or other applicable language? (I know I could do it in flash, but I'm interested in the other alternatives.)

For examples, I'm thinking of:

• this crossword gadget
• and this color-shifting game (really, anything by LabPixies)

Bencejoful (talk) 17:07, 16 April 2009 (UTC)

You might be interested in some of the standards-based madness at chromeexperiments.com. --Sean 18:32, 16 April 2009 (UTC)

Well, there are two components here. One is general javascript programming. The other is game programming. You can do game programming in any language—the key things that are different are that Javascript sets some pretty hard constraints on how you deal with graphics, what kinds of operations can be performed efficiently, and a lot of other things relating to how Javascript specifically interacts both with HTML and CSS as well as with the browser.

So if it were me, I'd first focus on Javascript in general. Build a simple Tic-Tac-Toe game using HTML tables, for example. Get a feel for the syntax and etc. From there, pick a somewhat more complicated project (say, checkers). Keep working up. As you get more familiarity with the language and the logic of games, when you look at things on the labpixies site and elsewhere you will be able to somewhat easily figure out how it must be done (e.g. the Google gravity code on the chromeexperiments page probably carves up the page elements into individual objects, then has some nice physics-like coding to deal with falling bodies, then goes through a timer loop moving each element according to the physics model, etc. — it's no doubt a lot harder than that in practice, but in terms of structurally breaking down the logic into its components, it is easy once you have some small association with the various elements at play in such a model). --98.217.14.211 (talk) 21:23, 16 April 2009 (UTC)

For 2D graphics in JavaScript, you need to look at the "<canvas>" extension. It's supported natively on every browser on the planet...except Internet Explorer. There is a plugin (courtesy of Google) for IE that solves that - although it's kinda slow. I wrote http://www.fmbaker.com/samegame/ using canvas - and I've been working on a 'god-game' "The Foot of God" http://www.sjbaker.org/tfog/ (think "Populous") using it and although that's FAR from finished, the graphics are close to working (sometimes you have to hit "reload" after you reach the page - I have a problem with preloading images). You can find documentation on "<canvas>" here: https://developer.mozilla.org/En/HTML:Canvas

For 3D - there is work in progress on adding OpenGL graphics to JavaScript too (there are hints in the canvas document about how they'll add it)...that would be a wonderous and beautiful thing and could well be a Flash-killer.

Outlook 2007 and too-big images

I seem to always have size problems in Outlook 2007 when pasting, or inserting, a small JPG or PNG file directly into a message — that is, as part of the message, visible in the window, and not simply a file attachment. Outlook always scales the picture larger. It appears to always scale it to 133% of its original size. Trouble is, the picture "Size" dialog box (reached at Picture Tools->Format->(Size button in the ribbon)) claims the scale is currently at 100%, and there is some text claiming an "Original Size:", measured in inches; both claims are shameless, bald-faced lies. If I order Outlook to scale the picture down to 75% then it appears to be pixel-perfect, as I want.

Does anyone know what the problem is here? Why does Outlook want my pictures to look larger? Tempshill (talk) 19:44, 16 April 2009 (UTC)

I have an idea - I get the same problem. My screen resolution is 96 dpi (right click desktop > properties > settings > Advanced) but when I paste images that are 72 dpi they will look too big. If I save the image with a resolution of 96 dpi, it will look right in all Office 2007 programs. /Christian

Firefox Ridiculous Mem usage

For some reason when I'm using Firefox, the amount of memory it uses builds up to ridiculous amounts after a few hours use, often as much as 800K, slowing it down significantly and requiring to both shut it down and also end the process using task manager, If I don't do that too, it stays there, using the same amount of memory and I'm unable to reopen it. Any idea why? Its 3.0 running on Vista btw--Jac16888^Talk 02:45, 17 April 2009 (UTC)

800k? That's NOTHING! 0.8Mbytes - that's probably one tenth of one percent of your computer's RAM! SteveBaker (talk) 03:40, 17 April 2009 (UTC)

Just so I know, what kind of memory does firefox generally use?--Jac16888^Talk 16:41, 17 April 2009 (UTC)

That really depends on what webpage(s) you are visiting and how many tabs are open (as well as what plugins are active). I've just created a clean install of Firefox 3.0.8 on Vista x64 and on my computer visiting the main www.google.com page uses 47Mb. I then installed the Flash plugin and loaded around 15 tabs of YouTube videos and it shot to over 300Mb. Closing them all down returned to the 47Mb fairly quickly. Although whilst writing all that I've just noticed that the usage has increased to 58Mb and Firefox hasn't changed page or even had the focus so I don't know what's going on there.... In fact just as I hit save it jumped to 62Mb although it appears to be holding steady now. ZX81 ^talk 18:40, 17 April 2009 (UTC)

Well I have the Facebook page open in one window (I know i know) and two Wikipedia tabs in another and its saying 200mb--Jac16888^Talk 19:58, 17 April 2009 (UTC)

Right now I'm on XP with FF2and 2Gb RAM, and it's only using 281,000 for 37 tabs, BUT they've been open all day. If I open and close a lot of tabs, it will shoot up to as high as 600,000 (beyond that it is too slow to tolerate so I restart it). Turning off caching appears to improve it, but only a little. Some of it is caused by tracking tabs for the Undo Closed Tab and crash recovery features,

To get rid of some of the leakage, change the configuration to release memory when the window is minimised. This is most effective if used regularly before the usage goes over about 150,000; beyond that it doesn't release much. If using multiple windows they all have to be minimised at the same time.

In the address bar, type about:config and hit enter. Right click anywhere and select New, Boolean. In the dialog that comes up, type config.trim_on_minimize, click OK, then select True and click OK again. Restart the browser.KoolerStill (talk) 06:15, 19 April 2009 (UTC)

However, because you're using an illegal version of Windows it's hard to say if that would fix the problem as expected (there is no official version called "Black edition" except the pirated version which also contains other pirated apps).

Browser Back button

Is the web browser Back button a legacy of the days of static HTML pages? Do current web designers frown upon it? Are there usability standards as to what an user experience must be when he hits the back button? Any links to articles or blogs would also be helpful. Jay (talk) 11:15, 17 April 2009 (UTC)

The Back button is supposed to do one thing: Take the user back - to the previous page (the one that was opened before clicking the link or button). (That's one reason why "META refresh" and JavaScript-based redirection are disliked by many - when you click Back, you get to the redirector page, which forwards you to the same page again.) --grawity 13:22, 17 April 2009 (UTC)

Current web designers that know what they are doing do not mind the back button at all. They plan for it. Current web designers who do not know what they are doing hate the back button because it exposes their limited ability to make dynamic websites. Instead of learning to do things properly, they attempt to break the back button. There are very rare cases in which breaking the back "function" (not really button) is necessary. Here is an example: You have a special web object that the user can type text into. It is not a text box, but acting very similar to one. You want the user to be able to backspace to delete text. However, the backspace is the keyboard shortcut for the back button. So, when the user has your little web object selected, you don't want the backspace to be a "back button click". In some browsers (ie: Opera) you cannot override the backspace key. -- kainaw™ 14:06, 17 April 2009 (UTC)

Things that matter if you do them twice - like clicking the "buy" button in an online shop - are submitted as a HTTP POST rather than the normal HTTP GET. The browser will warn you if you go back in that case. I guess the source for this is rfc2616 9.5. --h2g2bob (talk) 19:48, 17 April 2009 (UTC)

That is what I meant by programmers not knowing what they are doing. The server should recognize that the same user submitted a purchase (or clicked the buy button) twice. Going back shouldn't cause a problem. -- kainaw™ 21:25, 17 April 2009 (UTC)

So, the Back functionality is good, and is part of modern browsing. And breaking the Back functionality would mean not letting the user go to the current/cached version of the previous page, even if he is navigating across 2 or 3 different websites. There are secure websites likes bank sites that log you off if you click the Back button. Can this also be considered breaking the Back functionality? Jay (talk) 03:59, 20 April 2009 (UTC)

Don't know where you're based, but in the UK usability and accessibility guidelines from organisations such as SOCITM and RNIB, as well as WCAG 1 and 2.0 from W3C all state that web developers should do nothing that has the effect of disabling or overriding the user's browser settings. So yes, breaking the Back function is generally considered bad. I've never personally come across a bank site that logged you off for using the Back button, but as someone has said above, it does require careful coding to avoid unwarranted side effects.Elen of the Roads (talk) 23:23, 23 April 2009 (UTC)

Delete Key Launching Task Manager

Hi. Anyone heard of where the Delete key (one below 'insert' and 'Del' on the numpad) launches task manager screen on its own? Just pressing either of these keys brings up the task manager, and I don't know how to disable this so I can use the decimal point key on the numpad and the normal delete function.

Any help is appreciated, thanks. 161.181.53.10 (talk) 15:05, 17 April 2009 (UTC)

I've had this exact thing happen in Remote Desktop a couple of times, for 2 different reasons. First, someone had created a macro on the local box binding DEL to CTRL-ALT-DEL due to a physical handicap. The second time someone had left a screwdriver on the local console's keyboard, and it was pressing on CTRL and ALT, so my DEL completed the trifecta! Both rather unlikely circumstances, but they also both did happen, so YMMV. :) Arakunem^Talk 16:31, 17 April 2009 (UTC)

Sound problem

My sound is fuzzy. It crackles, like a radio approaching the edge of its range.

It's not a sound card problem, because it happened before I got a sound card and the brand new, mid-range sound card had no effect at all.

It's cured by restoring factory settings, but I don't want a cure, I want prevention. Factorising every three months is annoying.

Oh, and I've also moved house since it first happened. Twice. Vimescarrot (talk) 20:01, 17 April 2009 (UTC)

So it happened on two completely unrelated computers, on the second one with a number of speakers and soundcards, and at three different locations? That is highly unlikely. Perhaps the two computers were not completely unrelated, after all? Perhaps you used the same OS on them (an unusual OS)? (And, forgive me for asking, does other people also hear the distortion?) --Andreas Rejbrand (talk) 20:10, 17 April 2009 (UTC)

I completely understand your skepticism. Yes, other people hear it. The OS on the first computer (which, if it matters, was used in locations 1 and 2) was Windows XP; in the second computer, in locations 2 and 3, it was (and still is) Windows Vista. I tried multiple speakers (but only one soundcard...well, the built-in one) on the first computer. The second computer has tried different speakers as well as different soundcards. Vimescarrot (talk) 20:20, 17 April 2009 (UTC)

I agree it's highly unlikely, which is why I think something must have caused it - something which I'm doing. I use a webcam with a built-in microphone - someone suggested that could cause it, via feedback. Or something. Someone else suggested a virus, but no scan has found any trace.

My radio crackles when I use a hair-dryer. Kittybrewster ☎ 20:26, 17 April 2009 (UTC)

Yes, the only common factor is the user, and the user-specific activities and applications. I do not believe it is a virus, for then a quite rare virus must have infected two different computers. I agree that all audio input devices, such as microphones, are "suspicious". Try to disable them (temporarily). Also, are there any application you have used on all three computers? (Of couse, the application have to be quite uncommon, e.g. Microsoft Word is not qualified.) Or did you experience the distortion when any computer was new and "clean" as well? --Andreas Rejbrand (talk) 20:37, 17 April 2009 (UTC)

The computers were fine when new. I use mostly Internet Explorer (started on 6, am now on 8), a lot of Java, Windows Live Messenger and...that's pretty much it. Common activities are RuneScape and watching videos. I've uninstalled my webcam (which contains the microphone) but did not hear any difference in the sound. Of course, it's possible that the sound stopped getting worse, but since it's over such a long time period (a few months) it's difficult to tell... Vimescarrot (talk) 20:41, 17 April 2009 (UTC)

I it possible that you've got some sort of software program that's redirecting your "Line-In" or Microphone inputs to the speaker?

Also, stupid question the needs to be asked: When you replaced your speakers, did you also replace the audio cable that runs from your computer to your speakers?

Also, if your sound card supports EAX, you might try disabling that through your sound-card drivers. I used to have a soundcard that would get all staticy when that was turned on. (Never figured out why.) APL (talk) 15:52, 18 April 2009 (UTC)

Just to clarify if you don't want to read it, you calibrate it to zero first, using a perfectly flat surface. I imagine it detects its tiltiness the same way a Wii Remote does. Vimescarrot (talk) 20:35, 17 April 2009 (UTC)

accelerometer --Nricardo (talk) 01:55, 18 April 2009 (UTC)

The iPhone has a pair of accellerometers inside that detect when you tilt it or shake it or whatever. They detect when the phone is being accelerated. When the iPhone is perfectly vertical, the up/down sensor reports 9.8 meters per second squared - 1g - and the left/right sensor reports zero. When you tilt the phone, the up/down sensor reads a little less than 9.8 and the left/right sensor reports a little more than zero if you tilt it to the right - or a little less than zero when you tilt it to the left. If the phone is completely flat (sitting on it's back) then both sensors return zero. So the software can figure out exactly how the phone is tilted - so long as the value for 'g' is known. That's why some of the apps need to be 'calibrated' because 'g' varies depending on where you are in the world, etc.

The Wiimote doesn't work quite like that. It knows where it's aimed using a tiny camera to look for the two infra-red LED's in the bar that you put on top of your TV. It has accelerometers too - but they are only used for relatively coarse measurements of how fast the Wiimote is being moved when it's going too fast or when the camera isn't pointing towards the LED tracking bar. There is a new gizmo for the Wii that (IIRC) comes with the StarWars lightsabre fighting game which is supposed to have much more sophisticated accelerometers. SteveBaker (talk) 01:45, 20 April 2009 (UTC)

The Wiimote is perfectly capable of determining it's orientation without using the sensor bar. Several games work that way. Super Monkey Ball, Mercury Revolution, Marble Mania, etc.

What it can't do is handle motion and rotation at the same time. Which makes sense, because it only seems to have one set of accelerometers. You'd need at least two to separate out accelerations due to rotation and accelerations due to movement. APL (talk) 17:03, 21 April 2009 (UTC)

PPTP VPN considerations

Hi All,

We use have 2 LANs with separate ISP's. On both of these LANs we have dhcp enabled and both of them assigns ip address in the form of 192.168.1.x.

I've recently been playing around trying to get pptp to work on these so I can be on both networks on the same time (so i can manage/monitor on both networks, so am not really trying to bridge both networks completely).

I have been able to enable pptp on the router (a dedicated computer running pfSense on the target network ill call Network A) and connect to it successfully from the network I'm currently on (Network B). on XP, I can do a ipconfig /all and it lists the pptp adapter showing the ip I assigned on the router of Network A. My problem is I dunno what I have to do to specify which network connection should be used when I issue some sort of command: ie how do I ping 192.168.1.1 on Network A? It always defaults to pinging the ip on my current physical connection (Network B).

Do I have to change one of the LANs to use a different mask (192.168.2.x) to get it to work?

TIA PrinzPH (talk) 22:35, 17 April 2009 (UTC)

Yes, you will need to renumber one of the networks, otherwise the local route will win. Gavint0 (talk) 12:37, 18 April 2009 (UTC)

Am I allowed to name ISP's here?

I have been a subscriber with AOL BROADBAND in Scotland Uk for many years and have no issues with that. But recently, I have noticed that the longer I stay online, the slower the service becomes ie., slower, erratic and at times unresponsive. BUT when I disconnect and reconnect Hey Presto, the service goes back to being fast and slicky. Can I be forgiven for suspecting that I am being penalised the longer I stay on? Secondly, AOL used to have a LIVEHELP button that connected me in realtime with a LIVE helper who would answer problematic queries and help me to solve them. But for several months now, whenever I click that button, I get a message telling me that AOL are in the process of improving that service????????????????? and offering instead a 48 hour e-mail question and answer service. My question? Oh yes. Can I believe the second part of that summary? And how can I decide which is the best all-round alternative ISP in my area given my scepticism about AOL. Thanks.92.9.138.136 (talk) 23:37, 17 April 2009 (UTC)

AOL does seem to be in a downward spiral, constantly lowering services, losing customers as a result, then lowering services further to save money so they don't suffer a financial loss. The root cause is probably that they just took on too much initially. For example, they have their own browser (based on IE). Why ? Most ISPs are sensible enough to allow you to use your own browser. They also have their own e-mail system, instant messenger, bulletin board, news, etc. Most of that is overkill, since other web sites can provide all of that. So, they've set up a business model that requires a large staff to support, at considerable expense, with little benefit to the customers (since just about every add-on that AOL offers is available for free elsewhere). It's a bad business model. I can't make recommendations for other ISPs in Scotland, but perhaps others will do that. StuRat (talk) 14:56, 18 April 2009 (UTC)

AOL has been around for a long time. Their custom software once ran on the Commodore 64 and Apple II. There was no public data network for them to use, no standards for email or instant messenging, no preexisting client software, certainly not any free client software. The Free Software Foundation wasn't even founded until 1985. That's why AOL has custom versions of everything—because they were early adopters of everything. Not that I'm sorry to see them falling on hard times. Good riddance, and hooray for the open Internet. -- BenRG (talk) 21:34, 18 April 2009 (UTC)

Yes, long ago I called them and asked that they create a low-cost version of AOL that just provides the Internet access, without all the other crap. They didn't listen to me. StuRat (talk) 15:26, 19 April 2009 (UTC)

Open the start menu, click on your picture at the very top of the menu, and then choose "Change account type" (or whatever the name of the option is in English). However, it is indeed very possible that you already are an administrator. Then, maybe it is UAC that annoys you, or you might need to run the game as administrator. To do so, right-click on the game's icon, select "Preferences", "Compatibility" and check "Run this program as an administrator". --Andreas Rejbrand (talk) 11:55, 18 April 2009 (UTC)

Beware that this would give the game the power to mess up things which it couldn't otherwise do, so a downloaded game with a virus could cause more serious problems. StuRat (talk) 14:41, 18 April 2009 (UTC)

Rather than disabling the entire User Account Control, might I suggest simply elevating yourself when needed? To do this simply right-click the program/shortcut and select "Run as administrator".

TrueCrypt does not contain any mechanism or facility that would allow partial or complete recovery of your encrypted data without knowing the correct password or the key used to encrypt the data. The only way to recover your files is to try to "crack" the password or the key, but it could take thousands or millions of years depending on the length and quality of the password/keyfiles, on software/hardware efficiency, and other factors. —Preceding unsigned comment added by 82.44.54.169 (talk) 11:47, 18 April 2009 (UTC)

Do you remember anything about the password, like whether it contained an English word or any letters/digits/symbols that you're sure aren't in it? If you can narrow it down to a billion possibilities or less then brute-force password cracking might be feasible. I'd guesstimate that you could check ~100 passwords per second per CPU core on a modern PC. There's no known attack on a TrueCrypt volume that's faster than brute-force password checking. -- BenRG (talk) 16:50, 18 April 2009 (UTC)

Let's be realistic here - the whole reason you encrypted the file in the first place was to prevent "the bad guy" from doing precisely what you are asking to do! Why would you imagine it's even possible? Forget it - if the contents of the files are worth less than a million dollars - they're history. SteveBaker (talk) 01:00, 20 April 2009 (UTC)

Dim monitor

Are there ways to dim monitor screens further than the default buttons allow? I find it very hard to focus on a bright screen in an area without any lighting. The operating system I'm using is Windows vista on an LCD monitor. Thank you for your help. -- penubag  (talk) 12:18, 18 April 2009 (UTC)

You can use software for that (I can't think of any right now, though). The application simply changes the brightness of each pixel, so that the LCD receives a dimmer image. Also, you could try to wear polarizing sunglasses, at an appropriate angle (in fact, you can adjust the apparent brightness of the LCD by tilting your head). A very interesting approach would be to place a polarizing thin film just in front of the screen. Then you could rotate this to adjust the brightness. --Andreas Rejbrand (talk) 13:32, 18 April 2009 (UTC)

Many graphics drivers let you adjust the brightness via a control panel application. Perhaps you have an icon to open this control panel in the bottom-right corner (Swedish: meddelandefältet) of the screen, or in the Control Panel "folder". --Andreas Rejbrand (talk) 14:01, 18 April 2009 (UTC)

This will vary quite a bit by monitor. On mine I can go to Control Panel + Display + Settings tab + Advanced button + Color tab. From there I can change the "Target Gamma" or all 3 "Color Splines" (for Red, Green, and Blue), either of which can make it dimmer. Another hint is to change the Desktop to black (or at least a dark color) and also change the window backgrounds to dark colors. I find white text on black background far easier on my eyes than the reverse. I've changed my Wikipedia profile to do this, as well. StuRat (talk) 14:33, 18 April 2009 (UTC)

A minor note: I believe that it is more likely to vary, in general, by graphics card, not by monitor. --Andreas Rejbrand (talk) 15:39, 18 April 2009 (UTC)

Thank you, that method works okay but that doesn't dim the back light, only makes the LCD stronger. You method did help some though.-- penubag  (talk) 04:30, 21 April 2009 (UTC)

PHP Hit Counter Help

Hi. I'm trying to create a PHP hit counter. I want it to display the number of unique visitors to the site. If the user has a cookie from the site, it does not increment the count. If he doesn't, it increments the count. In either case, it prints the number. Here's what I have so far. Right now, it isn't incrementing. If I get rid of the conditionals, it increments, but doesn't care if you've been to the site before. Thanks.

			<?PHP
				if (isset($_COOKIE['id']))
				{
					$filename= "counter.txt" ;
					$fd = fopen ($filename , "r") or die ("Can't open $filename") ;
					$fstring = fread ($fd , filesize ($filename)) ;
					echo "$fstring" ;
					fclose($fd) ;
				}
				else
				{
					setcookie( 'id', 'counter', time()+(60*60*24*7));
					$filename= "counter.txt" ;
					$fd = fopen ($filename , "r") or die ("Can't open $filename") ;
					$fstring = fread ($fd , filesize ($filename)) ;
					echo "$fstring" ;
					fclose($fd) ;
					$fd = fopen ($filename , "w") or die ("Can't open $filename") ;
					$fcounted = $fstring + 1 ;
					$fout= fwrite ($fd , $fcounted ) ;
					fclose($fd) ;
				}
			?>

—Preceding unsigned comment added by Tim james 5 (talk • contribs) 12:47, 18 April 2009 (UTC)

Looks basically fine. In the else clause you may want to echo $fcounted after you set it (rather than $fstring before) if you want the new user to see the newly incremented counter. -- KathrynLybarger (talk) 17:40, 18 April 2009 (UTC)

Your code is not thread-safe. If two people hit the site at the same time, the following may happen:

1. Visitor 1 hits the code: $fc = fopen($filename, "w")... erasing the contents of the file.
2. Visitor 2 hits the code: $fstring = fread($fd, filesize($filename)); ... reading an empty file.
3. Visitor 1 finishes up, saving the count.
4. Visitor 2 continues, opens the file ("w" erases the contents), adds 1 to $fstring (which is empty), and saves $fcounted (now 1) to the file.

The end result is that your count will reset to 1. You must use flock (php command is flock) to ensure the file cannot be read while it is being written. -- kainaw™ 20:02, 18 April 2009 (UTC)

Or even better, as some more complicated PHP hit counters do (like BBClone), have a series of possible files it can open in a queue, so that you can accommodate, say, 7 hits at the same time and not lose any data. Also, I suspect there are a lot of things that will hit your page (like bots) that won't allow cookies. In such cases looking at the IP address itself might prove more useful. --98.217.14.211 (talk) 03:04, 19 April 2009 (UTC)

Thanks for the replies. It works now. Here is the final code:

			<?PHP
				if (isset($_COOKIE['american'])) {
					$filename = "counter.txt" ;
					$fd = fopen ($filename , "r") or die ("Can't open $filename") ;
					$fstring = fread ($fd , filesize ($filename)) ;
					echo "Visits: $fstring" ;
					fclose($fd) ;}
				else {
					setcookie( 'american', 'counter', time()+(60*60*24*7));
					$filename = "counter.txt" ;
					$fd = fopen ($filename , "r") or die ("Can't open $filename") ;
					$fstring = fread ($fd , filesize ($filename)) ;
					echo "Visits: $fstring" ;
					fclose($fd) ;
					$now = time();
					while ($now + 1 > time()) {
					}
					$fd = fopen ($filename , "w") or die ("Can't open $filename") ;
					$fcounted = $fstring + 1 ;
					$fout= fwrite ($fd , $fcounted ) ;
					fclose($fd) ;}
			?>

I'm not sure what I changed, but it seems to work now.--Tim james 5 (talk) 17:36, 20 April 2009 (UTC)

Your code is still not locking the counter file. Therefore, you are begging for two users to hit the page at the same time and reset your counter to 1. Waiting 1 second to write to the file isn't helpful. It just postpones overwriting the file for 1 second - technically making the problem worse. -- kainaw™ 22:36, 20 April 2009 (UTC)

Encryption

Is there a way to encrypt a single text file? I wouldn't mind either encypting the text in the file, or the file itself. --RefDeskAnon (talk) 18:06, 18 April 2009 (UTC)

There are many, many ways; too many to list. A few easy possibilities, you could zip the file with a password, use an online encryption tool, put the text file in a TrueCrypt volume, or try this self modifying text program which acts just like notepad but with a password to secure your text. 8I.24.07.715 ^talk 18:28, 18 April 2009 (UTC)

Beware of snake oil (cryptography). That online encryption tool looks completely worthless. fSekrit is a good idea, but it looks like it was written by a crypto novice and is pretty weak (no salt or IV). I think modern ZIP encryption is fine and it might be your best choice, but you'll probably have to save the file to disk in plaintext before you encrypt it, which might be a problem depending on what you want the encryption for. TrueCrypt is a good choice except that the container overhead is going to be pretty large for a single text file (at least 256K). Don't use random encryption programs you find on the Web, stick to products with Wikipedia articles (and whose articles don't say they're snake oil)products that were mentioned in this thread. -- BenRG (talk) 21:44, 18 April 2009 (UTC)

It all depends on how secure Op needs the encryption to be.To just stop your friends from looking at your diary for instance, the above methods should be fine.

See GPG. --194.197.235.70 (talk) 00:36, 19 April 2009 (UTC)

Someone mentioned Zip encryption. It's actually pretty rubbish, and there are a whole bunch of programs that will unpassword a zip file nearly instantly. The encryption on RAR files is better, at least I guess this from the fact that password braking programs for rars rely on brute forcing. Gunrun (talk) 08:13, 20 April 2009 (UTC)

Open SSL has command line tools to allow you to encrypt an arbitrary text string, and I am pretty sure that there are some 3des utilities and blowfish utilities that come standard in a lot of *nix systems that will do the same thing. As a practical matter, GPG/PGP is what you want though. Shadowjams (talk) 19:52, 20 April 2009 (UTC)

The original ZIP encryption was weak, but strong AES encryption has been in the official ZIP specification since 2003 if not earlier. At least PKZIP and WinZip support it. Info-ZIP apparently doesn't, judging from the man page, and moreover it still implements the weak encryption without so much as a warning. I suppose it might be dangerous to rely on other utilities' ZIP encryption for the same reason. RAR also had weak encryption initially but that was fixed some time ago, and since there's only one vendor for RAR compression you can be sure you're getting the strong encryption if you use a recent version. On the other hand it's a proprietary undocumented format and the software costs money.

I wouldn't trust random command-line encryption utilities even if they're bundled with major Unix systems. Unix boxes traditionally shipped with a crypt utility which was insecure even on 1970s hardware. A Google search for "linux blowfish" turned up bcrypt as the first hit. It's available as a Debian package and it has a Wikipedia page and the page doesn't say it's snake oil, but there are a lot of warning signs in the documentation. I downloaded it and sure enough it's a joke: ECB mode, no integrity check, and probably other less obvious problems. So I'm going to have to change my earlier advice. Don't rely on Wikipedia to tell you what isn't snake oil.

I'm not so sure that GPG is what the original poster wants. GPG is a complicated set of tools with a nontrivial learning curve. A lot of people just want to encrypt a file with a password. Although GPG is at least widely used and supported and written by people who know what they're doing. Those are advantages, I'll admit. -- BenRG (talk) 00:49, 21 April 2009 (UTC)

Those are all excellent points I wish I'd made. Just two things: I don't think RAR's format is undocumented (there are open source RAR utilities including crackers); and RAR can be free, if not actually open source (not sure if the RAR version that's in the common repositories is open source or not). RAR apparently changed their encryption method with version 3, and it appears they use a key derivation function in a loop now, although I can't find the documentation.

Setting up RAID arrays / need disk imager suggestion

Okay, so I've got two 250 GB HDDs and two 1 TB HDDs. I want to set up two RAID arrays: the TB drives in RAID 1 (mirroring), and the two 250 GB HDDs in RAID 0 (striping); important stuff, photos, documents, videos, etc. go on the TB array, installed apps and the OS go on the other one. I know RAID 0 doesn't provide a huge performance benefit, but it's slightly better than plain spanning, and will let me install as many games and crap as desired without space concerns.

Am I right to assume that my motherboard's hardware RAID controller (Intel® ICH8R Southbridge RAID) will allow me to set up two separate RAID volumes? Will I hit any issues at all with this plan?

Also, both the 250 GB HDDs have data on them already. I'm going to need to do some disk image juggling to keep that data; anyone have suggestions for good disk imaging software?

Edit: Going to amend this with one more question: if I take an HDD out of a RAID 1 array, will it be accessible without issue by any other computer?

-- Consumed Crustacean (talk) 23:24, 18 April 2009 (UTC)

Yes the ICH8R should allow you to create multiple RAID volumes, at least 2 and probably 4, although this may vary depending on your motherboard implementation.

Do the 1Tb disks contain data? If not then the simplest solution rather than disk imaging is probably just to copy the data to them first and move it back when the RAID-0 is setup. I'm sure you are aware of this, but I just want to mention it in case, RAID-0 provides no redundancy. If EITHER 250Gb disk fails then you will lose the entire volume and you may want to consider keepin ghtme as separate disks or just having another RAID-1 mirror with the 250Gb disks, but obviously that's up to you though.

You can break a RAID 1 array at any time and have two exact copies of the same disk - I do this all the time, it's VERY convenient. This is assuming the RAID-1 volume wasn't in a rebuild state obviously. Hope this helps! ZX81 ^talk 23:55, 18 April 2009 (UTC)

Okay, cool. I know about RAID 0's limitations, and I'm still debating it, but like I said it's intended only for installed programs and the OS. The installed games, mods, and applications have basically filled a whole of one of the 250 GB drives, and I've still got several others that I've had to uninstall because of space issues. I wouldn't mind simply being able to install to that partition without any regard for how much space is left, rather than having to juggle between two.

The imaging software would be used to keep the MBR and things straight, though I suppose I could just use fixmbr or whatever the equivalent is in Vista. -- Consumed Crustacean (talk) 00:08, 19 April 2009 (UTC)

On running the HDD through SequoiaView, I've found a few things that I can do to save space on the main partition (relocating Steam to the TB array will save a hell of a lot of space and cause no inconvenience, for instance), so I'll just RAID 1 both sets. Thanks for the help. -- Consumed Crustacean (talk) 00:44, 19 April 2009 (UTC)

Gateway Laptop completely freezes when AC cable is unplugged.

Hi everyone,

Somewhere around half of the times that I unplug my AC plug from my laptop when it's turned on the computer completely freezes. Clock doesn't move, mouse stops, everything. The only way to fix it is to hold down the power for a few seconds until it turns off then turn it back on.

I can't think of anything I did that might have caused this, and I've ran numerous virus/spyware scans (ad-aware/avg/hijackthis). This leads me to believe something in the hardware is failing, or it's some setting I changed somehow without knowing.

The fact that it doesn't always happen bothers me, also rarely when I remove or plug in a USB device while the laptop is on, it does the same thing.

I have a Gateway M-6851, running Windows Vista SP1. Any ideas? Thanks!

Chris M. (talk) 00:19, 19 April 2009 (UTC)

I'm no expert, but it sounds like it's causing a momentary power fluctuation - which sometimes is bad enough to crash the laptop but sometimes not. Exxolon (talk) 02:38, 19 April 2009 (UTC)

That's just what I was thinking. Try unplugging the other end of the power cord first, and see if that makes a difference. Also, if you have an outlet hooked up to a wall switch, try turning it off at the wall switch before you unplug. You could also use a power strip and flip that switch off before you unplug.

Awesome window manager

I need some help with the Awesome window manager. I basically want it to look like this. I'm looking for the name of that font, what terminal/console that users is using and what the best file manager would be for Awesome. File managers always look horribly when I use them with Awesome. --BiT (talk) 00:51, 19 April 2009 (UTC)

Also, can someone tell me what file managers are being used in the aforementioned link and in this one? They both seem to have the GNOME icon but they don't look like Nautilus or anything like that. --BiT (talk) 01:06, 19 April 2009 (UTC)

Pretty sure the file manager is Thunar. It's the default file manager for Xfce. Indeterminate (talk) 00:41, 20 April 2009 (UTC)

Are you sure? I've tried Thunar and the form looks rather like it but as you can see the Thunar manager doesn't have the GNOME icon in the corner. --BiT (talk) 01:12, 20 April 2009 (UTC)

Yep, I installed it on my ubuntu system here and it's got a little gnome icon in the corner. I don't know what build they're using in that picture. Indeterminate (talk) 01:40, 20 April 2009 (UTC)

But I'm currently using Thunar with Awesome and there isn't a GNOME icon there? Also, have you got any idea what theme those people are using? --BiT (talk) 01:47, 20 April 2009 (UTC)

Hmm, strange. Maybe it depends on what distribution you're using and what version of Thunar. Anyway, sorry I can't help much, I haven't used AwesomeWM before. Indeterminate (talk) 09:54, 20 April 2009 (UTC)

I believe it's a "plugin" for the blender (software) 3D modeller - right? That being the case, I think you need to find the blender instructions for installing plugins from the blender website - at which point (hopefully) it'll be obvious. SteveBaker (talk) 00:30, 20 April 2009 (UTC)

Umm... I don't think it is, Wikipedia says it is a stand-alone piece of software (http://en.wikipedia.org/wiki/MakeHuman), not a plug-in for anything else... 144.138.21.31 (talk) 03:38, 20 April 2009 (UTC)

Hmmm - evidently it WAS a blender plugin back in 2005 (which is about the last time I played with it) - but has since gone stand-alone - so at least I'm not completely crazy! SteveBaker (talk) 21:19, 21 April 2009 (UTC)

Learning VisualBasic

I downloaded the visual basic thingy...from...somewhere (it was a long time ago). Is the in-built tutorial (which, from what I did, is pretty in-depth) a particularly good or bad way to learn my first programming language? I ask because I'm unable to learn anything from it. Vimescarrot (talk) 12:40, 19 April 2009 (UTC)

I've never seen this tutorial but the language I'm most familiar with is visual basic and I've done a lot of work with it. After I had learned some I had grabbed VB 6 for dummies (on amazon), which I thought was impressively well written and easy to understand, even though I had done a lot of it, the parts that were new were very clear. If you're using a new version (.net, or 2008 for example) there are equivalent books I assume would be valuable. On the other hand, a free but very effective tool to learn visual basic is the wikibook. Several of my friends learned with this source (link) and feel that they understand it well enough to use it. It also goes into some more advanced things the dummies books wouldn't, which is nice for the future. Chris M. (talk) 15:10, 19 April 2009 (UTC)

Thank you for that information but it didn't actually answer the question I asked. ;-) Vimescarrot (talk) 19:05, 19 April 2009 (UTC)

Sorry, the answer was more subtle then I had intended. You said that you weren't able to learn anything from it. I said that it's not hard to learn from several other sources, and so by saying that I was implying that it wasn't a particularly good source, or I would expect you'd have more success. 74.218.161.17 (talk) —Preceding undated comment added 19:56, 19 April 2009 (UTC).

But the logic of that is flawed. It may be my sheer ineptness which prevents me from learning, not the tutorial. Vimescarrot (talk) 21:11, 19 April 2009 (UTC)

I don't know the answer - but unless you have a specific need to learn VB (eg for your job) - I would pick a different language to learn as your first. VB is an evolutionary dead end. Learn Java first. SteveBaker (talk) 00:31, 20 April 2009 (UTC)

"VB is an evolutionary dead end." Care to back that up? Granted, I haven't done any VB development in years, but I still see job ads for VB and Microsoft keeps updating it so I'm not sure how VB is an evolutionary dead end. A Quest For Knowledge (talk) 01:28, 20 April 2009 (UTC)

I was recommended VB as an easy language. But I'd be happy to hear reasons to learn something else. Vimescarrot (talk) 10:54, 20 April 2009 (UTC)

Well, the main problem I have with VB is that it combines legacy features from VB6 with modern OO features and Microsoft provides no real distinction between the two (i.e. Len(myString) versus myString.Length()). For those that care about code quality, things like that will drive you nuts. Another option is Small Basic.[4] What kind of applications do you want to write? A Quest For Knowledge (talk) 12:20, 20 April 2009 (UTC)

I wasn't thinking of writing any kind of application. I just wanted to learn it. I spend all of my free time on my computer; I thought it was a useful, non-timewasting thing to do...(I'm happy to hear the answers to this, but may I point out my original question remains unanswered? :) ) Vimescarrot (talk) 14:07, 20 April 2009 (UTC)

Think up a specific application that you could use. In the work it takes to figure out how to implement it, you'll end up learning a ton. There's really no other way I know of to do it—you have to jump in with two feet. Feel free to ask on here for good "beginner" applications (don't try and write a BitTorrent client right off the bat!). How about a simple address book? Tackling that will show you the basics of GUI development, data processing, maybe even some mild databasing. All good things to know how to do! --98.217.14.211 (talk) 22:48, 21 April 2009 (UTC)

(outdent). Oh, you want your question answered? Why didn't you say so!  :) OK, which tutorial are you referring to? Is it the "Visual Basic Guided Tour" found in help? If so, no it doesn't look like a good way to learn programming. If it's "Creating Your First Visual Basic Program" also found in the help, that looks a little better. I recommend going out and buying an intro VB book. Alternatively, you can take an intro to programming class. A Quest For Knowledge (talk) 14:18, 20 April 2009 (UTC)

Thanks. I can't remember what the tutorial was; it was on an old PC, so I don't actually have access to VB now anyway. No doubt I'll be just as incompetent at it no matter what method I try to use to learn it. Vimescarrot (talk) 17:04, 20 April 2009 (UTC)

• The first programming language I learned was Visual Basic.NET. It's a very common beginner's language. It is also very powerful. It makes learning other languages much easier, so there's no reason not to learn it. Visual Basic 6 is much different from Visual Basic.NET, by the way, and Microsoft no longer supports VB 6. You can't do nearly as much in VB 6 as VB.NET. You can do almost anything you want in Visual Basic.NET -- anything you can do in C++ or Java. In fact, unlike C++, it has built-in garbage collection. You can also use it in web pages via ASP.NET. The programs run very fast, too, because they use the .NET Framework, although the end user has to have the .NET Framework installed in order to run your apps. It's very intuitive, although I wouldn't mind having C-style braces to aid code readability. Multi-line comments would be nice, too. My favorite part of coding in VB.NET is the IDE -- Visual Studio. I've tried Eclipse for Java, and that is one of the biggest pieces of shit on planet Earth. (No wonder they give it away for free.) Visual Studio's debugger tells you exactly what the problem is and highlights the error. The auto-complete function saves you a lot of time, too.--Tim james 5 (talk) 17:36, 20 April 2009 (UTC)

VB6 is in my estimation reasonably easy. VB.NET is not as easy but it is more regularly structured. Languages that are more regularly structured (Actionscript, as one random example) are in my opinion a LOT easier than either VB or VB.NET. --98.217.14.211 (talk) 22:45, 21 April 2009 (UTC)

This is purely WP:OR (although I am a published author in this field), but a lot of people who say that VB6 is easier than VB.NET started learning VB with VB6. Thus, VB6 seems easier because they already knew it. IMHO, if you took someone who was completely new at VB, VB.NET would be easier to learn than VB6.

Creative SoundBlaster Live! Sound Problems

Hi.

I have a Creative SoundBlaster Live!, its not the one with the full chip, but the cut-down version. (I like the MIDI SoundBank manager better on this version.)

I have two problems with this sound card which cropped up last year. I was on XP SP2 and it worked fine, upgraded to SP3 and it was still fine for a while, but then these problems started appearing. Me being the type of person I am, I had to re-install Windows after fiddling with it. I am now using XP SP2 again and the problems are still here.

1.) If I have my sound volume very low, the sound card will actually turn its self off. i.e. nothing plays, not even the small buzzing that usually comes out of speakers. The only way to cure this is to move the main slider (called playback) on the Mixer up to a higher level, let go of the mouse and it plays the XP error noise (like it should) and then move it back low again.

2.) If I use certain programs then my P.C. after a little while, randomly each time between about 10 and 30 seconds, will pause with the sound jamming and playing the last "second" over and over again. The only way to get rid of this is to do a hard reboot.

Known programs that cause this error:

Audacity - version 1.2.6 (Recording or Playing), Notation Player - version 2.1.2

It might help to know this piece of information. Its a nightmare trying to find drivers from Creative. They have this soundcard in about 5 or 6 different varieties. It is possible I have the wrong drivers installed. I used Creative's Auto-Update service to determine what my soundcard was, and then manually downloaded the drivers from their website. I manually downloaded them because Creative seems to not Auto-Update everything like it claims to.

I have disabled the onboard audio, and as this sound card wasn't with the P.C. (Its basically been built from scratch, but with HDD and RAM from an older P.C. which used an onboard chip. The old sound drivers (C-Media) won't uninstall and that could be the problem. Everytime I go to uninstall them it says uninstalling and then asks to re-boot. When it boots its still there in the Control Panel. I have done this under my account, in safe mode using the Administrator account. and using TuneUp Utilities 2008 to try and remove it.

If anyone knows what could be the problem I would be grateful to know your thoughts. Thanks. Elven Spellmaker (talk) 13:06, 19 April 2009 (UTC)

I've owned almost every Creative soundcard since the Soundblaster 1 and the most joy I ever had was with the SBPro. It was the most compatible card ever, and it worked until I had to retire it. Ever since, I've found all SB cards deteriorating over time... ranging from annoying little sound crackles to the computer not even picking it up. I think your card has had its life (since it did work at one point with XP). Use your onboard sound... this has caught up over the years to be as good to sometimes better than Creative's mid-range offering. Creative's top-end is for a minority of audiophiles or for people with extra cash. On one of my older computers, I've thrown out the Audigy 2 and enabled the onboard 6 channel sound - and it actually sounds better, not to mention some games actually picking up the 3D sound. Onboard is also more efficient as there is no overhead of having to use the PCI bus. Sandman30s (talk) 14:41, 19 April 2009 (UTC)

I would use my Onboard sound, if I didn't use MIDI so much. The general MIDI DLS that Windows uses is appalling. Also I think that the C-Media drivers might confuse the onboard chip. Elven Spellmaker (talk) 16:17, 19 April 2009 (UTC)

Re the drivers, the only way would be to delete the drivers themselves after removing all C-Media entries from the registry. You can always download Yamaha/Roland soundfonts (not free but worth it and cheaper than buying a soundcard) if the default ones are that bad. I thought that the default Windows General MIDI samples (in XP onwards) have always been better than the default AWE32/Audigy/Live! soundfonts anyway. Good luck, elven friend!

Script to replace an image (part 2)

I need some help with writing a greasemonkey script. I thought I had it figured out, but I just can't seem to make it work. I'd like the script to replace any instance of a certain image on a webpage with another image of my choice. So for example, on this page I might like to replace this image and this image with this and this

From looking at other userscripts, I've come up with:

var findString = ['http://www.ucmp.berkeley.edu/geology/mag_anom.GIF']; // array of image src
var newString = ['http://upload.wikimedia.org/wikipedia/commons/3/37/2_russian_street_cats-crop.jpg']; // array of new image src

var findString = ['http://www.ucmp.berkeley.edu/geology/curr2.JPG']; // array of image src
var newString = ['http://upload.wikimedia.org/wikipedia/commons/9/9b/Domestic_cat_cropped.jpg']; // array of new image src

var allImages, thisImage;

allImages = document.evaluate(
    '//img[@src]',
    document,
    null,
    XPathResult.UNORDERED_NODE_SNAPSHOT_TYPE,
    null);

for (var i = 0; i < allImages.snapshotLength; i++) {
    thisImage = allImages.snapshotItem(i);
    for (var j = 0; j < findString.length; j++) {
        if (thisImage.src.match(findString)) {
            thisImage.src = thisImage.src.replace(findString[j], newString[j]);
        }
    }
}

but it's not working. What do I need to do? Many, many thanks for any help with this —Preceding unsigned comment added by 82.44.54.169 (talk) 18:52, 20 April 2009 (UTC)

Here's a working version without the XPath stuff:

// a hash table where the images we want to replace are the keys,
// and the replacement images are the values
var substitutions = {
    'http://www.ucmp.berkeley.edu/geology/mag_anom.GIF':

            'http://upload.wikimedia.org/wikipedia/commons/9/9b/Domestic_cat_cropped.jpg'

};

var allImages = document.getElementsByTagName('img');
for (var i = 0; i < allImages.length; i++) {
    var thisImage = allImages[i];
    var subst = substitutions[thisImage.src];
    if (subst)
    {
        // we want to create a new image rather than modify the old
        // one's src in order to get the width and height of the new image
        var newImg = new Image();
        newImg.src = subst;
        thisImage.parentNode.replaceChild(newImg, thisImage);

Script to replace an image (part 3)

Last question, I promise! I'd like to achieve something similar to this script, but instead of just google it could be modified to work on any image on any page.

hmm, I've been mucking about with it, but on other sites it just displays the images (the google logos in default state) in the top left hand corner of the page, or seemingly chooses a random image to replace.

You should put in some logic along these lines:

if (document.URL.indexOf("http://cnn.com") == 0)
{
   // replace CNN's logo here
} else if document.URL.indexOf("http://google.com") == 0) {
   // replace Google's logo here
}

And so on. For followup questions like these, you should just add on to the original query. --Sean 14:12, 21 April 2009 (UTC)

I've condensed the question to one heading. Sorry to be a complete annoyance, but I really have no javascript knowledge at all, and I'm not sure how to use those lines of code you provided. They don't work on their own and I don't know how I should integrate them into the google image script.

Base classes (C#)

I have a handle management class called Win32Handle (written in C#) and specialized derived classes for objects like job objects, processes, threads, etc. In Win32Handle I want to have a Duplicate() method which all derived classes will inherit. The problem is, instead of the Duplicate() method returning a Win32Handle I want it to return a specialized class instance. For example:

ProcessHandle ph = ...;
ProcessHandle ph2 = ph.Duplicate(ProcessAccess.Terminate);

instead of:

ProcessHandle ph = ...;
Win32Handle ph2 = ph.Duplicate((int)ProcessAccess.Terminate);

How can I do this? --wj32 ^t/c 02:49, 20 April 2009 (UTC)

TrueCrypt's security

Why does everybody (internet forums, wikipedia, etc) believe that TrueCrypt is really secure? How should a skeptical proceed to test this assertion?--80.58.205.37 (talk) 10:23, 20 April 2009 (UTC)

Mostly because it is open-source for public scrutiny, and the rationale for all the security design considerations are very well documented, and it uses well-known ciphers. As opposed to proprietary software who claim to be secure because of their "amazing 4096-byte parallel matrix" closed-source cipher. decltype (talk) 11:00, 20 April 2009 (UTC)

If the ciphers are secure, and the implementation is straightforward, then it should be secure.

Type of DC socket in a HP laptop

The laptop shows it is powered only when the power plug is inserted and kept at certain angle. I did some research on the internet and found out that the problem lies in the socket in the laptop. One of the tests was to remove the battery and see if the laptop goes off if the angle is slightly changed. HP's website unfortunately does not have a manual for this model (ze5700). I have never opened this laptop before, if the socket is soldered to the mother board I cannot replace it anyway, so i won't open it in that case. If the socket is of non-soldered type, perhaps I can buy one and replace it. ( is it a generic part? or i have to order it from HP?). Can you please say which type of socket this laptop posseses?. —Preceding unsigned comment added by 131.220.46.24 (talk) 10:47, 20 April 2009 (UTC)

I've never seen your exact model so I accept I could very well be wrong, but I've personally never seen a non-soldered power socket on a laptop motherboard. Soldering is simply the quickest/easiest/cheapest way for them to do it and I would assume that yours is the same too. I also doubt that your socket is faulty, the socket itself doesn't really have anything in it that can break, but from you're describing the problem sounds like part of the solder connecting the socket to the motherboard has come off and you only get a proper connection when you angle it a certain way forcing the connection. Whilst you could try getting it repaired under warranty (if it's still valid?) it's not really a manufacturing defect and it's only really the sort of thing that can happen if it's dropped or knocked whilst the lead is in and I'm afraid finding someone to try and resolder it is probably the only solution. Even then it might not work very well though, we had a Dell laptop that we tried to fix for this problem and it just kept breaking again and in the end we had to get the user another laptop. I appreciate my entire post is an assumption on your laptop, but I hope it's of some help. ZX81 ^talk 11:26, 20 April 2009 (UTC)

There are really two kinds of problem - one is that the socket is bent inside and only makes contact when you bias the plug in that particular way. The other is that one of the solder joints that holds the socket to the circuit board has cracked and is only making intermittent contact. If you are lucky - and it's the first of those things then perhaps you can gently bend the connector back to where it makes good contact. It's usually the bigger strip of metal that contacts the outside of the plug rather than the thin one that goes up the center of the plug. However, in likelyhood - you'll have to either replace it or re-solder it - and that amounts to the same thing in the end. If you can find a local computer repair store, they should be able to do it while you wait...but how much that's gonna cost is anyone's guess. Anyone who can solder can do this...and learning to solder isn't that hard (I'm self-taught - and I'm a klutz - but I can do stuff like this easily). Fry's have low-budget soldering irons for $10 and solder for $5 - so perhaps this is time for you to learn! It's such a simple job that if you happen to live near Round Rock, Texas - I'll do it for you for free. In the unlikely case that the socket is literally broken (I think that's unlikely) then you'll first need to remove the old one - and that's a bit harder...you need a way to remove the old solder first and that requires another tool called a 'solder pump' - which will probably set you back another $15. No matter what, you've obviously got to get it fixed - so that's that. SteveBaker (talk) 21:11, 21 April 2009 (UTC)

Port Forwarding

I'm looking for information on how to forward ports on the Ambit DOCSIS cable modem. —Preceding unsigned comment added by Shadowclouds6635 (talk • contribs) 18:21, 20 April 2009 (UTC)

You might be able to change the settings by going to this page, but it looks like your model allows your ISP to disable settings from their end, so it might not be possible.

Also you can try using username: admin password: cableroot and see if that shows more options. These are just internet rumors, so don't take my word for anything. Indeterminate (talk) 19:22, 20 April 2009 (UTC)

hmm, I came across a similar thing about the ISP rewriting the firmware or something, to prevent port forwarding. I've phoned and asked them and they say they do not prevent port forwarding, so I'm at a loss as to what to do. The link you provide doesn't work, and there are no options for changing settings at the router login page. Are there standard unblocked ports already forwarded which I could use? Like 80 or something? I'm trying to let my friend connect to my server from her computer. Shadowclouds6635 (talk) 19:30, 20 April 2009 (UTC)

From your response it seems that what's probably going on is that your ISP is blocking port 80 (or 25, or whatever else) for their own reasons (viruses, to create price discrimination, some other reason). If your cable modem is a level 2 device (what I'd expect), then port forwarding is irrelevant. You might be more interested in figuring out how to port forward on the IP device connected to your modem (router or computer). If your cable modem is a combined router and modem, then access the router portion of the modem and setup the settings as the other responses and your instructions suggest. In many cases cable modem configurations are not accessible (legally) by the user. But a cable modem at its most basic level won't be doing TCP level restrictions. Anything doing that is more than a simple cable modem (which is certainly possible). What ISP is this? Shadowjams (talk) 08:11, 21 April 2009 (UTC)

Virgin Media. The port I wish to forward is 5800, so my friend should just have to type my ip address such as xx.xxx.xxx.xxx:5800 to connect. I've added the exception in the Windows firewall, I just can't think of what else to do. There are no changeable options in the modem page, even after I log into it with the password, it just lists the version number of the modem, downstream and upstream info. Thank you for helping me.

MicroSd and MicroSDHC compatibility?

Well, you can put it in, and it shouldn't break anything, but it might not work. SDHC is backwards compatible with SD, meaning that SD will work in SDHC readers[5], but SDHC won't work in SD-only readers.

Restore image within VBox

This is an interesting question too which i am not sure there is an answer. I have 2 laptops, the firstlaptop is running windows XP Pro. The second laptop (of different design than the first) is running Ubuntu 8.10. The second laptop has VBox OSE installed. My goal is to take am image of the first laptop and restore that image on a virtual hard drive within a virtual environment ran by VBox. The only problem i am encountering is that when i try to start up that virtual environment i get a Blue screen of death shortly after HAL loads. Is there anyway i can prepare the first laptop to function in a virtual environment? Or is there a way i can change VBox to emulate the hardware found on the first laptop? Or is there any other ways that i can get this to work? Not only would i like it to work when i restore an image from another computer but i would also like it to work when i map a hard drive from another computer using VBox's built in raw disk utility (as i am encountering the same problem with the BSoD and what-not). Any advice / links / URLs / hugs and/or cookies (chocolate chip please) would be very useful and/or appreciated. Thank you. – Elliott(Talk|Cont)  20:49, 20 April 2009 (UTC)

digital camera

My digital camera is pretty new. it used batteries really fast, like needs new batteries every 5-10 pictures. is there something wrong? Wikivanda199 (talk) 22:24, 20 April 2009 (UTC)

What kind of batteries does it use? Are you using the recommended ones? There might be a low-power setting you can switch it to, which could help. --Tango (talk) 22:31, 20 April 2009 (UTC)

How much time passes between pictures? What kind of camera is it(make / model)? – Elliott(Talk|Cont)  22:45, 20 April 2009 (UTC)

Most cameras use rechargable, special batteries, but some cheaper models use standard, non-rechargable AA(A) batteries. I believe that cameras using standard AA(A) batteries will require quite frequent battery replacement, but certainly (unless it is a really cheap camera!) not as often as every 5-10 pictures. --Andreas Rejbrand (talk) 07:50, 21 April 2009 (UTC)

Not convinced by the AA perspective. I have a Pentax K100D, not exactly an expensive camera but not cheap either. It takes AAs and it can take around 500-700 shots with them. Certainly the proprietary battery-packs that some cameras take aren't 'better' than normal batteries, they're just designed so you have to use their replacements instead of normal batteries. Most dSLR cameras i've seen take AA batteries. 194.221.133.226 (talk) 15:07, 21 April 2009 (UTC)

Scratch that last comment - seems that's more just because i'm a Pentax lens only so only really looked at Pentax. Seems Nikon and Canon use their own batteries. 194.221.133.226 (talk) 15:11, 21 April 2009 (UTC)

Cameras that use AA batteries work with NiMH rechargeable AA batteries. The non-rechargeable batteries you're thinking of are alkaline batteries, which are available in AA size. Plenty of expensive cameras use AA batteries and plenty of cheap cameras use proprietary batteries. My Canon PowerShot SX100 gets hundreds of shots on a pair of AA rechargeables. There's no way a camera could only get 5–10 shots on a single charge (regardless of battery type) unless there were long periods of standby between the shots. It's not even physically possible to drain a battery that fast. -- BenRG (talk) 15:40, 21 April 2009 (UTC)

• Provide some more details. What kind of batteries (AA, AAA, proprietary?) and what type (lithium, alkaline, NiMh)? What's the camera brand and model? Anything else strange? Shadowjams (talk) 08:04, 21 April 2009 (UTC)

Yeah - there is something very odd going on here. If you put a new set of disposable batteries into the camera - turned it on and pressed the shutter button five to ten times over (say) 20 seconds - and then found that the batteries were dead - they'd be so hot, you'd burn yourself touching them! You simply can't discharge a battery that fast without it getting insanely hot. In fact, they might even get so hot that the chemicals inside might boil and then the battery would explode! Since none of these terrible things have happened to you (presumably), there must be something else going on. So either you're talking about taking a picture, leaving the camera turned on for 20 minutes, taking another picture, waiting 20 minutes and so on (in which case, just remember to turn the camera off when you're done using it)...or, possibly, you have rechargeable batteries that aren't properly charged - which suggests that they are either duds or the charger isn't working or something). Dead batteries will sometimes "come back to life" after a few minutes of recovery time - then die again shortly afterwards - so if your charger were completely dead (or not plugged in or something) then you might take the rechargeables - think that you're charging them (when really you aren't) and because they've rested for a while, you get a few more shots out of them before they die again. However, after you've repeated this procedure a few times, they'll die and stay dead. So this kinda fits the possibility that you have a dead battery charger. I suppose another possibility is that you aren't letting them charge for long enough. SteveBaker (talk) 20:37, 21 April 2009 (UTC)

I had this experience once when the only AA cells I could buy where the non alkaline "heavy duty". These hardly lasted for 20 pictures, when normally 100 or 200 pictures come off alkaline cells. Are you using fresh alkaline cells? Graeme Bartlett (talk) 20:56, 21 April 2009 (UTC)

Problem with Java applet

I'm programming a java applet for a computer science class. The applet is basically a simplified version of a minesweeper game.

I have provided code which i think completes the requirements, but when i compile the code and run the container HTML, it has a few strange bugs.

Basically it says i've won as soon as i click any square. I've looked over the code many times and still can not find the problem. Additionally, Netbeans 6.5.1 shows no errors.

Java Cipher

I would like to make a new Java cipher that can be loaded with Cipher.getInstance("MyNewCipher"). I've looked at a lot of code examples and they all have something in common that doesn't make sense to me. See this example. If I copy that as is and attempt to compile it, I get an error because Cipher is not imported, but the class extends Cipher. If I import Cipher, I get an error because there is no constructor and Cipher does not have a null constructor. How is it that apparently everyone else in the world can extend Cipher without importing it and then magically get a null constructor out of it? -- kainaw™ 01:52, 21 April 2009 (UTC)

The Cipher with the no-args constructor is com.sun.portal.kssl.Cipher which is not the same as javax.crypto.Cipher. Perhaps Bouncycastle source code has more relevant examples. I'm not sure but you may need to sign you cipher jar for it to work; see [7] and google. 88.112.62.225 (talk) 04:12, 21 April 2009 (UTC)

Printing seamless tiles

Is there a simple tool (Windows or Linux) that can print a page full of seamlessly tiled, err, seamless tiles (like the ones you can use as a tiled desktop background)? I tried searching on Google, but I can't for the life of me figure out how to search for that...tiled printing, which I assumed to be the term for that, is actually the name for rasterbation which is the opposite of what I want to do, and all other combinations of search terms I can think of give me tutorials on how to create seamless tiles (which I already know) and repositories of printable seamless textures (which is useful, but I still don't know how to print them).

ImageMagick can do everything. For this, try:

composite -tile tiled_image.jpg -size 1200x1600 xc:none tiled_output.pdf

That will give you a 1200x1600 tiled image that you can print. You can twiddle the dimensions to suit your paper size. --Sean 12:49, 21 April 2009 (UTC)

It's easy to do in GIMP too (that's a free paint program).

Less number of Seeds

You are paying for the films you download, I hope? --Andreas Rejbrand (talk) 07:47, 21 April 2009 (UTC)

No, a low number of seeds will only affect the download speed, or if there is not a distributed copy of the file among the seeds you will not be able to complete the download. The problem you describe, of the playback skipping throughout the film, is caused by an incomplete download. Where the film jumps it means you are missing small "chunks" of the download. You must go back to your torrent program and complete the download to view the film properly. 8I.24.07.715 ^talk 08:30, 21 April 2009 (UTC)

While you shouldn't download illegally, this is still a very valid question. What the above poster said is right; if you get the file downloaded to 100%, it doesn't matter if there are 1000 seeds or 1, because you won't get it to 100% unless the CRCs match (although there are ways to trick the CRC to match, but that's a different story). Another problem could be that you are getting a poorly encoded file, or a very well encoded file that your computer isn't good enough to handle. My desktop can't handle 720p h.264 too well, for example. --Wirbelwindヴィルヴェルヴィント (talk) 15:32, 21 April 2009 (UTC)

As far as I know there are organizations out there right now injecting fake data into torrents of Hollywood movies. The fake data can't end up in a completed download, but it can make downloading a lot less efficient, especially since the .torrent file only stores hashes of chunks of 256K to several megabytes while files are usually transferred in chunks of 16K. When a 1-megabyte chunk fails the hash check, the client can't immediately tell which peer is responsible since it might have received parts of it from several different peers. Also, in the worst case the whole megabyte has to be downloaded again just because of 16K of bad data. -- BenRG (talk) 01:15, 22 April 2009 (UTC)

Agree 100% with above. Even if it doesn't damage the hard drive, your computer uses cache memory and that data will be lost when the power is pulled, which alone is enough to lose or corrupt files. Also, harddrives could have the heads parked wrong or something and cause some sort of failures, although I'm not sure what comes into play if you use solid state hard drives. I've seen power outages cause all sort of havoc, even with surge protectors and APCs (well, 1 APC, but still, the possibility is there). --Wirbelwindヴィルヴェルヴィント (talk) 15:24, 21 April 2009 (UTC)

In most systems, pressing the power button once will trigger the shutdown command. You can press the button and walk away. The computer will (eventually) shut down. Of course, it may get hung waiting for you to verify that you don't want to save changes to some files you have open. -- kainaw™ 15:48, 21 April 2009 (UTC)

And holding it down forces a shutdown by the hardware, not by the OS (or something like that). 24.6.46.177 (talk) 01:18, 22 April 2009 (UTC)

I mean, if you really can't wait a few seconds to turn off your computer when it isn't responding (which shouldn't happen that often anyway), you can still always just pull the plug from the outlet, flip the switch on the power supply on the back of your computer (if you have one), or flip the switch on your power strip, and it would be the same. --76.167.241.45 (talk) 16:22, 22 April 2009 (UTC)

Berne convention and the Internet

Hello. I have three questions about the Berne Convention as it applies to the Internet. I hope this is the appropriate desk for these. ^^

1) I've heard that anything you write in a blog is automatically subject to the Berne Convention. Is this true? Would this apply to anything written in web pages in general? (Also, what would happen if the web page disappeared? Would the rights hold?)

2) If I upload a file to a file hosting service, would it apply to the Berne Convention as well? Would the file type make any difference?

3) Are there any other ways to apply a document to the Berne Convention besides these (if at all)?

Thanks in advance, Kreachure (talk) 21:14, 21 April 2009 (UTC)

1. Depends on what country you are in. If you are in a Berne country, then yes, it automatically goes under Berne, because you are a citizen of said country and Berne is automatic.

2. Uploading is not a creative act. Berne comes into effect whenever you create something new. Did you create the thing that you are uploading? Then Berne still applies. File type doesn't matter. Note that you can lose your Berne-given copyright ability if you, say, agree to transfer the copyright (which some file uploading services and etc. make you do, so they don't have to worry about being accused of copyright infringement).

3. I think you're kind of confused on what's being covered by Berne. Not "documents"—think instead, "expressions." If that expression is in the form of a document, so be it. If it is in the form of a speech, no different. How about a song? No difference. A building? No difference. A Microsoft Word file? No difference. What matters is the jurisdiction in which it is created (under Berne or not). At least, that's my understanding of it. --98.217.14.211 (talk) 22:42, 21 April 2009 (UTC)

Thanks for your reply. Being in a jurisdiction not covered by the Berne Convention seems very unlikely, so yeah, my questions were assuming you're inside the Berne Convention coverage. I have another question from what you said though, related to proving that it's you who created something first: Is blogging, making a web page, and uploading safe ways to prove that it was indeed you who created whatever it is you created first, so that the Berne Convention applies automatically to you as soon as you 'publish' (or upload, etc.) them (and no one else can claim that it was them who created it instead)? Might there be safer ways on the Internet to prove it? I came up with file hosting because I presumed that there's some timestamping involved in the process (which would prove that it was you who created the thing first), but maybe there are safer services to 'secure' your rights through the Berne Convention? (Or, maybe there's simply no need to worry about timestamps and such in the first place?) Kreachure (talk) 23:22, 21 April 2009 (UTC)

See poor man's copyright. The best way is to avoid the internet altogether if you are really worried about such things. Personally if I were doing a poor man's copyright I would do it with hashes and services (like Usenet) which distribute said data widely (making it increasingly unlikely that I was in collusion with any given site or company). --98.217.14.211 (talk) 00:13, 22 April 2009 (UTC)

how can people just hack into gov. computers??

how is it possible to simply hack into a government computer or power grid or whatever? Let's say there wasn't any social engineering with email either. I mean, I just don't get it, if this capability exists couldn't someone technically shut down 80% of every internet end-user because we're all on the same windows operating systems? or couldn't the entire backbone of the internet run by the DoD or DARPA or whatever be shut down? If gov. computers are vulnerable it just seems like nothing is safe. why isn't there trillions of dollars of credit card fraud if you can hack F-35 data filtering 16 digits of credit card data on a 128 bit encryption should be child's play. Any inight into this? thanks, -Rob 173.30.14.113 (talk) 00:26, 22 April 2009 (UTC)

I can't remember numbers, but I think a large proportion of hack-jobs involve insiders, which presumably makes the job considerably easier. And for some reason, I think decryption is one of the worst ways of hacking since it's infeasible to attempt to crack some of the stronger algorithms out there (2⁴⁰⁺) - it's a lot "faster" to look for exploits like open ports and badly-configured control panel areas. x42bn6 Talk Mess 00:39, 22 April 2009 (UTC)

Further... If you read an article in mainstream press that states something like "Someone hacked the CIA," it does not mean that someone hacked into a CIA computer that contains anything secure. It means that someone hacked into the CIA webserver, which is obviously accessible from the Internet, and is not considered a "secure" or "high risk" server. Often, the web servers for secure locations aren't even housed in the same building (or state) as the real servers that are used for storage of information. -- kainaw™ 01:20, 22 April 2009 (UTC)

You say that - but just today I read that many terabytes of design documents for the Joint Strike Fighter were copied by hackers - probably from China: http://online.wsj.com/article/SB124027491029837401.html In this case it seems they hacked into computers belonging to the developers of the jets - and from there got into Pentagon computers.

What amazes me is that this information is stored on computers that are connected in any way whatever to the outside world. The best security is physical security - if there are no wires and no wireless connections - then it's going to be very tough indeed for the information to get away. But evidently, even the best kept secrets of the US government are out there on servers that you can reach from the Internet. Incredible. SteveBaker (talk) 03:03, 22 April 2009 (UTC)

I read the paper today and i think it said the real real top secret data was physically separated from the internet, but yes, still that terabytes could be stolen out of thin air is just incredible to me. how could there be that many loopholes that net admins aren't monitoring!?? -Rob 173.30.14.113 (talk) 03:23, 22 April 2009 (UTC)

Unless I'm reading that article incorrectly, it does not make any sort of claim that hackers got into Pentagon computers. It specifically states that the Pentagon computers are not connected to in any way to the Internet. It states that the hackers got into computers that monitor the flight tests, which record a lot of information about performance and such. Sure - that's bad. However, it isn't the same scale as hopping from AOL to Lockheed to the Pentagon and then downloading all the nation's top secret info. I also like the way the article scales up: It appeared to come from China, but very well could have been anyone since online identities may be spoofed ... It is possible it was China ... China would do something like this ... We are damn certain it was China because we need another reason to convince everyone that China is evil! -- kainaw™ 05:32, 22 April 2009 (UTC)

You don't have to hack into them, see Data spill (and that lists only a tiny fraction).

Laptop graphics - will it run..

Hello, I'm thinking about getting hold of some older RPG games to run on a laptop - the amount of memory and processor speed it has seems much greater than that required. However I'm not sure about the graphics - it has an "Intel Mobile 945 Express chip" which I think will use software for much of the rendering - I've heard that sometimes such chips just don't work..

Games I am considering include the old Baldur's Gate and Icewind Dale series, and maybe Neverwinter Nights

I've done dxdiag successfully to 9.0c.

Should I expect problems (esp on Neverwinter Nights) ? Thanks.77.86.67.245 (talk) 00:38, 22 April 2009 (UTC)

BG and IWD shouldn't have any problems running, but it depends on the rest of your hardware. If you have a decent CPU and RAM, then you might manage to get NWN running. What are your other system specs? --Russoc4 (talk) 01:29, 22 April 2009 (UTC)

You beat me to it - update - I downloaded a Neverwinter demo (couldn't find demos for BG/Icewind) - curiously - it worked - even with everthing turned on (shadows etc).

However that was just as far as getting the 3D display up and running, moving around, menus etc.

I think I'll take the risk that it continues to work on a full version - unless anyone knows better.?

Is there any reason I should expect problems later on? I can still supply specs if wanted (tell me what figues you need).FengRail (talk) 02:12, 22 April 2009 (UTC)

Intel graphics chips are extremely problematic. You might get lucky - but I wouldn't bet on it. If you'd named an older nVidia or ATI chipset, I'd have said "Yes" with a high degree of confidence. SteveBaker (talk) 02:04, 22 April 2009 (UTC)

Infected

My brother's laptop with XP won't load the desktop when started up. When running in safe mode, I got the error code 1073741819, which apparently means the computer is infected with a virus. All the fixes I see online involve going to start and then run..which is impossible since the desktop won't load! Any ideas? 174.16.93.99 (talk) 01:26, 22 April 2009 (UTC)

Try to start in safe mode: (press F8 as the computer is booting up)

if computer starts shutting down

1. Press CTRL+ALT+DELETE.
2. Click the Task Manager button.
3. Click the Processes tab.
4. Click the Image Name column heading to sort the processes alphabetically by name.
5. Look for a process named Msblast.exe. If you find it, click the name to select the process, and then click the End Process button.
6. Close the Task Manager

Then go to here and download the tool and run it.

Viruses

I just downloaded Dr. Spyware to run a scan, and it found 21 infections of these two viruses: Trojan.CWS and Trojan.ClientMan. First, what exactly are they? Second, this pretty much confirms the reasons behind my computer freezing and crashing and what everyone has said about Windows Live OneCare sucking. Of course, the reason I took it was because some guy at FutureShop recommended it to me. Does anyone working at those electronic retail stores really have a clue about what they're doing? --Whip it! ^{Now whip it good!} 03:29, 22 April 2009 (UTC)

Hey Whip, re: the various viruses/trojans - I'd just google each term, read the summary on the first few lines to get an idea of what each one is. The following rant, is all WP:OR and IMO only. First, most of the people you find in tech stores are either going to be older folks just supplementing their income, or younger kids either working through school, or looking to get into the technology field. Also, stores are going to have "hot items", sales folks are told what items to push, because of a markup or promotional gig. Live One Care is M$, so it's gonna have a brand recognition advantage. I won't get into what I think about Best Buy. So the answer to your question is: NO, they don't really have a clue - that's not meant as a violation of NPA, just that the folks who do have the ability in the technology fields, don't work those type of jobs. Get yourself a free copy of Spybot S&D, or AdAware - then protect your self with a good AV program. The top free ones would be (AVG, Avast, or Avira). All IMO as I said. — Ched :  ?  03:48, 22 April 2009 (UTC)

Thanks, and I do have Spybot S&D, which is why I'm so miffed that these viruses got under the radar. BTW, when Dr. Spyware "cleans" the infections, does it really get rid of them? Cause I have the free version. --Whip it! ^{Now whip it good!} 05:08, 22 April 2009 (UTC)

As a general policy, I do not certify infected machines as sanitary unless they have been freshly reformatted. You cannot ever be absolutely certain beyond any reasonable doubt that an infection is in fact gone.

With that said, when I am, however, forced to eradicate an infection manually, I use a combination of HijackThis, Process Explorer, Process Monitor, and RootkitRevealer. (Note: These tools are designed for advanced users. Use them carefully under the supervision of someone knowledgable that can provide advice, or seek a qualified friend to do it remotely for you.)

My advice is this: if the machine is used to transmit or store sensitive data; play it safe. It's a whole lot easier to reinstall Windows than it is to clean up identity theft.   — C M B J   04:19, 23 April 2009 (UTC)

P.S. To verify the integrity of a single file, scan it with Jotti and Virus Total. This will test the file up against 30+ different virus scanners.

For future reference, when you are deciding which anti-virus solution to use on your computer, take a look at the latest benchmarks. According to the charts, OneCare has 81.1% detection rate, whereas Kaspersky has 97.1% and AntiVir Premium has 99.7%.   — C M B J   04:28, 23 April 2009 (UTC)

Don't trust an antivirus or antispyware product just because it reports an infection that another one doesn't. Some of these products are outright scams which tell you your system is infected so that you will pay for the registered version that can uninfect it. Even the legitimate products (I gather Spyware Doctor is in that category, if that's what you meant by "Dr. Spyware") often report false positives. The vendors don't have a lot of motivation to reduce false positive rates because it helps their bottom line, both by encouraging unregistered users to register and by creating the impression that the product is actively fighting off barbarian hordes when in reality it's just sitting there wasting RAM and CPU. Note the quote from the review at the bottom of the Wikipedia article: "in our trial scans, Spyware Doctor repeatedly flagged several dozen harmless cookies as potential threats, more than any other antispyware product we tested." Were those Trojan.CWS and Trojan.ClientMan infections that it flagged just cookies? If so, you're not infected. -- BenRG (talk) 12:54, 22 April 2009 (UTC)

It depends what program you're using to download the torrent file. I know LimeWire and FrostWire allow you to preview what you're downloading, playing only the percentage that has been downloaded so far, but I can only say that about audio music files. Don't know about movies. --Whip it! ^{Now whip it good!} 03:47, 22 April 2009 (UTC)

I don't know of any bittorrent client that will damage a file if you open it for viewing before its done. Keep in mind, however, that sometimes you won't be able to view the file. 1) bittorrent clients do not download the files in order. If you don't have the parts at the beginning of the file, you cannot view it. 2) Some filesharing clients seem to use some sort of cache mechanism I've never bothered to figure out, so the file isn't where you think it is until it's done. I'm not sure if I've ever seen this in a torrent client, but it's pretty common in programs like Limewire. APL (talk) 04:03, 22 April 2009 (UTC)

Firefox 3 tabs

I'm not sure if this is belated or if I'm just missing something, but I thought the tab bar didn't show if there was only one tab. I just recently installed Firefox beta but uninstalled it shortly after, but maybe it affected Firefox 3.0 since this was about when I started noticing this.

How does YouTube generate its unique IDs

YouTube is using rather short, 11 characters long, unique IDs to identify their videos (see for example this video), and I'm wondering how they generate them and make sure there are no clashes? My assumption is that they generate a standard UUID (36 characters), base64 encode it (22 characters) and finally only keep the first half of the string (11 characters). However, by doing so, isn't there a risk of getting duplicate IDs? What is the theory / reasoning behind generating such short IDs? Laurent (talk) 09:37, 22 April 2009 (UTC)

Conversely, what would be the point of generating longer IDs? As long as there are sufficient IDs for all the videos, does it matter if they are 11 characters or 22 characters? Well, yes, because humans don't much care for long strings of random characters. If the URLs are too long, people will feel the need to abbreviate them. In the event of a collision/duplicate ID, youtube can just modify or regenerate the second ID. While there are some very good reasons to make UUIDs secure, none of them apply to youtube video/page IDs. Besides, your suggested "shortened" IDs provide 64¹¹ possibilities—roughly 7.3x10¹⁹ (73 quintillion) unique identifiers—well more than youtube is likely to ever need. – 74  10:58, 22 April 2009 (UTC)

Yes 62¹¹ (62 = 26 lower case a..z + 26 upper case A..Z + 0..9) is a big number.

To prevent duplication I would imagine that they would implement some sort of numbering scheme eg start at 0 and work up 1,2,3 etc - to prevent codes looking like "aaaaaaaaaaa" "aaaaaaaaaab" etc they might perform some sort of add followed by bit shift to make the strings look more random - what the exact proceedure is I don't know. — Preceding unsigned comment added by FengRail (talk • contribs)

They don't need to avoid colliding with other people's ID generators like UUIDs do, which makes the problem much easier. They could just use a counter that increments once for every video that's uploaded. If the system is too distributed for that, there are still ways they could densely pack the ID space—for example, each server could request blocks of 1000 IDs from a master server as needed. I don't know how many videos are on YouTube, but I think it's less than 2³⁰, so they shouldn't need anywhere close to eleven characters—five should be enough. (And if those ran out they could just bump the length.) But the identitiers are much longer than that and they look random, not sequential. One possibility is that they're using some sort of counter but then obscuring it, e.g. by encrypting it with a block cipher and a fixed key. That would still guarantee no collisions (because block ciphers are invertible). I'm not sure why they'd want to obscure the id, though. Another possibility is that they're generating random IDs and hoping there won't be any collisions. In that case I hope they're aware of the birthday paradox, which says that the probability of a collision will rapidly go to unity when the video count exceeds 2³³ ≈ 8 billion videos, a number I can imagine them actually reaching some day. They could avoid random collisions by checking with a central server, but if they're going to serialize everything through a central server then it would be easier to just use a counter. -- BenRG (talk) 12:17, 22 April 2009 (UTC)

Many thanks all for your help. I wish it wasn't so much WP:OR so that I can add the result of this discussion to the UUID article. I ended implementing a short UUID algorithm using the BenRG's suggestion - i.e. I store in my database a unique number that's incremented each time it's read. I then encrypt this number using a block cipher and a fixed key and finally base64 encode it so that's it's usable in a URL. Again, thanks for your help! Laurent (talk) 15:10, 22 April 2009 (UTC)

Just wanted to add the following observation. YouTube video IDs are made of eleven base-64 characters (A-Z, a-z, 0-9, - and _). However, for the last character in the ID, only 16 out of the 64 characters are uniquely used. (For example, in the video pF7snTyCrJs, you can use s, t, u, or v as the last character to get the same video. There are 16 groups of four sequential characters that follow this pattern, so there are really only 16 unique values for the last character.) Thus, the total number of unique IDs is 64¹⁰ × 16 = (2⁶)¹⁰ × 2⁴ = 2⁶⁴. In other words, the internal ID number is 64 bits. --Bavi H (talk) 03:23, 23 April 2009 (UTC)

Please help me understand more about java applets/content panes.

I want to modify a program that i just completed for a class, and add extra functionality. The program is basically a java applet which allows the user to play minesweeper. I want to add the contents of the current applet to a Jpanel or something so i can add a little section above the game where the user can change the game difficulty by pressing one of three buttons.

What i dont understand though, is how to get the contents of the applet to put it on a Jpanel in the first place. I talked to a friend who happens to have years experience with Java and he told me that there should be a place where the code uses .add, and i dont see it. How is the content added to "Applet", which The public class "MineFinder" extends?

If anyone could help me to better understand what is happening, and how to add the information displayed by my applet to a Jpanel for me to mess with, i would greatly appreciate it! Thanks!

screensharing

I have been reading about remote desktops. I have used remote administration, in that the techies at work prefer to do things this way when staff phone up with queries that are not simple. I know that there are various ways to share screens, and that this lets you virtually look over someone's shoulder -- great for explaining an aspect of a project to a co-worker, e.g. a pdf. What I am trying to find is a way to look at the same webpage at the same time, with the ability to point to and annotate stuff. For example, let's say I phone my brother to choose a present for our parents. I go to mythologicalfemalewarrior.com to find something suitable, and invite him to the page I found. I click on one item, he says he prefers another and moves his mouse to it, and my cursor moves too. Is there a service like this? BrainyBabe (talk) 16:58, 22 April 2009 (UTC)

What you might be looking for is VNC. Setting it up might be a little complex if your not really IT, but it can be done. Hope this helps – Elliott(Talk|Cont)  19:19, 22 April 2009 (UTC)

 

If remote desktop is acceptable, take a look at this list of remote desktop software. TeamViewer, for example, is free for personal use, requires zero (and I do mean zero, as it automatically bypasses host and client firewalls,) configuration, and overall handles bandwidth very well. VNC, which is available for Linux, Mac, and Windows, should also be considered as a viable solution. A KVM switch is more akin to what you describe, but it would not be as practical.

If you need any further assistance, or if remote desktop is simply unacceptable, feel free to give me a holler. I'd be glad to help.   — C M B J   03:34, 23 April 2009 (UTC)

Where can I get a supercheap big TV or LCD display

hi there, thanks for any leads or tips you can give me, Wikipedians! I am a PHD student in Los Angeles, California and my colleague and for research purposes (we analyze TV, film and online video content) we need a big flatscreen TV or LCD monitor (maybe about 30inches but could be smaller) for supercheap (almost free or free!) due to our tight budget. Where would be a good place to find such a thing? I know this is a long shot, but this site was recommended to me as somewhere which might come up with a good answer! thank you very much! —Preceding unsigned comment added by 128.125.239.87 (talk) 17:16, 22 April 2009 (UTC)

Since you are in Los Angeles, there are refurb factories nearby. They take returned monitors/tvs and check them to see if they are in fact broken (and make minor repairs). The ones that work are resold at a fraction of retail cost. I purchased a 42" LCD television that was $1800 retail for $600 refurbished. Come to think of it... My printer was $300 retail, but I paid $50 refurbished. My two monitors on my computer were $400 retail, but I paid $150 refurbished. My laptop was over $2,000 retail. I paid $900 refurbished. That is the way to go, in my opinion. However, you state that you are a PhD student. You must be going to a university. I've worked at many universities and they all have a supply office which allows you to "borrow" things that aren't being used by others. I borrowed 32 computers (with monitors, keyboards, mice, desks, etc...) once to do networking research. -- kainaw™ 18:04, 22 April 2009 (UTC)

Yes. Some refurb factories will sell direct to the public. Some may be under contract to only sell to certain dealers. You are in LA though - so there are many refurb businesses. I see no reason for all of them to be under a contract to sell only to certain dealers. Another option, if you are still looking, is to purchase from a rental company. Again, there are a lot of rental companies to choose from in LA. Along that line, there are a lot of pawn shops, but my experience with pawn shops in LA is that they will give you about 1% of retail when they buy from you and charge 90% of retail when they sell stuff. -- kainaw™ 04:25, 23 April 2009 (UTC)

It's a common symptom of a mouse with a broken tail. The cable bends and flexes every time you move the mouse and wires are really not good at doing that so they break. When they do, one of two things happens - either you can't move the mouse in one axis because the metal broke and the wire is disconnected - or (as you've found) the insulation between the wires breaks and one of them shorts against the next - then the mouse won't stop moving in one direction. Wiggling the wire will sometimes restore function for a while - but it's going to do it again after another couple of minute's use. I've thrown away literally dozens of mice over the years that failed in exactly this way. If you're desperate and you are handy with tools - you can de-solder the cable - cut maybe three inches off of the end and solder it back again...but I've bought perfectly usable mice for $5 - so I don't think it's worth the effort.

Unless it's a wireless mouse - I which case electromagnetc interference could cause it - I get similar effect at ~11pm as the motors in the central heating go off - shouldn't happen to a digital signal - but does. (Before anyone asks - yes the motors are sparking and should be fixed)FengRail (talk) 04:09, 23 April 2009 (UTC)

Blu-Ray

Does anyone else hear wonder why blue ray, is so successful, it this where we are going in the next 20 years, isn't the whole 3d shape of a dvd out of date with growing flashdrives, highspeed internet and frostwire. "Blue ray lasers" have a wave legnth of 405 metres which is still within the range of light visible by the human eye, can a ray outside that range still be burned? —Preceding unsigned comment added by Ryan Prevost Baldwin (talk • contribs) 22:14, 22 April 2009 (UTC)

Blu-Ray is much higher quality than DVD. There is no other viable competitor. With Blu-Ray, if I want to watch a movie, I just pop it in and watch it. With high-speed Internet, I can download a movie at lower quality (Blu-Ray is 1080p and our on-demand HD is 1080i). Of course, I can't watch it right away because it takes about 8 hours to download the movie. I can drive to Blockbuster and rent a Blu-Ray version of a movie I don't have faster than waiting for it to download. As for flashdrives, it is possible to put movies on many different storage formats. Discs are easy to store. The case is just about the right size for scanning a stack of blu-rays and easily seeing which one you want to watch. So, this all comes down to asking why DVDs were so popular when everyone had VHS tapes or why CDs were so popular when everyone had cassette tapes or why cassettes were so popular when everyone had LPs or why the next storage medium will be so popular when everyone has blu-rays. -- kainaw™ 03:24, 23 April 2009 (UTC)

Good use for a Caps Lock key?

Does anybody know of a good use for a Caps Lock key? One day while at work I realized that the only time I ever hit the caps lock key was by accident, so I found a screwdriver and pried it out of my keyboard. I now have a new & improved 103-key keyboard (patent pending) and love it, but I also have a useless caps lock key cap that I don't know what to do with. Any suggestions?

Real question: Can I do the same with my laptop? Can laptop keys be removed as easily as desktop computer keyboards without doing real damage? I have a Toshiba Satellite A205 series. -- Tcncv (talk) 23:45, 22 April 2009 (UTC)

On my Toshiba Satellite Pro A100 I can remove and reattach keys without problems. An alternative solution would be to remap the capslock key to do something useful. Algebraist 23:48, 22 April 2009 (UTC)

If you have a word processing software, you can always set case in it if you made a mistake. I don't really use the caps lock but some people might need it *cough* Oprah *cough*. Kushal (talk) 01:01, 23 April 2009 (UTC)

I'm also a rabid caps-lock hater. Generally, I lever off the keycap, pour plenty of super-glue into the hole beneath - then cut the bottom quarter inch off the bottom of the keycap and epoxy the cap back in place. Sure, I could remap it - but that hardly expresses my distaste adequately. As an alternative - you can get one of these [8] and glue that onto the capslockectomy site. As for the left over key...hmmm...high explosives? SteveBaker (talk) 01:55, 23 April 2009 (UTC)

I just tell the computer to remap the caps lock key to nothing. --jpgordon^∇∆∇∆ 02:26, 23 April 2009 (UTC)

The Colemak keyboard layout replaces Caps Lock with a second Backspace key; you might give that a try (or, as jpgordon said, just remap it to nothing instead of removing it). – 74  02:43, 23 April 2009 (UTC)

I use the caps lock key rather often. When someone claims that a computer is not responding, I press the caps lock key. If the little light turns on, the computer is still functioning. If it doesn't, the computer is no longer responding to the keyboard. This often shows how bogged down it is. If it takes 5 seconds or so to turn on, the computer is running at max processing power on something rather nasty. For me, it isn't for capitalizing text, it is a quick PC diagnostic key. -- kainaw™ 03:18, 23 April 2009 (UTC)

First of all caps are very useful - there got it off my chest. As is the caps lock key. I like to press caps lock, scroll lock, and num lock in rapid succession and watch the lights go on and off - who needs drugs.

Uses - scrabble - that's quite a good score. Otherwise make a pendant - sell it to a geekFengRail (talk) 04:06, 23 April 2009 (UTC)

I use the caps lock key reasonably often, for, I guess, its intended purpose: connecting to an IBM mainframe, which likes to be talked to in all-caps. Something of a special case (ho ho) though. 93.97.184.230 (talk) 07:37, 23 April 2009 (UTC)

I use caps lock as a backspace and my older laptop's caps-lock key wore out and fell off. There was no way to put it back (glue might have worked but with my skills I had probably jammed the rest of the keyboard too). I think you can remove it carefully if you are not planning to put it back. --194.197.235.70 (talk) 09:15, 23 April 2009 (UTC)

DRM strip

i downloaded the Robot Chicken Star Wars Specials and can play them on iTunes 7.6, but on iTunes 8, it says that my computer is not authorized to play the videos. I can play them on QuickTime, but can't convert them. I've already paid for the videos and don't want to buy them again. Can i use a program to get rid of this DRM?

PS: I've tried re-authorizing my computer, but even though i can play songs and other videos, i can't play these two videos.

Permanent call tracing with a PBX

Does permanent call tracing, or at least a harder-to-forge version of call display, become easier to set up if one is using a private branch exchange? NeonMerlin 04:21, 23 April 2009 (UTC)

Linking excel data with word documents

While preparing reports i have to prepare documents in microsoft word in which there are a lot of tables.The values come from the result of calculation in excel.Is there any way to link the values in both documents so that whenever something is changed in excel it is changed automatically in words. —Preceding unsigned comment added by 120.89.108.128 (talk) 07:45, 23 April 2009 (UTC)
