Hi all, I have a website running a off-the-shelf CMS (GeekLog). I have some basic grasp of PHP and MySQL, enough to have made a couple of changes, but I'm not so hot. I have plans for some upgrades, and have been considering renting a coder for not too much (therefore I'm not going to be able to afford the cream of the crop). What is the general way to allow an unknown coder to modify my website?

I'm not so worried about there being anything to steal (although if he changes the passwords on me and sells the domain to someone else I'd be annoyed...), it's more than he may have to be working on the underlying code base, and so wouldn;t want the thing to come crashing down.

Memory addressing?

I am not sure exactly what it's asking. But, by reading it, it would seem that 4 bytes or 232 bytes would be the answer, but that would seem too obvious? 143.43.8.32 (talk) 03:21, 3 April 2008 (UTC)[reply]

It's 232 (which is 4,294,697,296), not 232. "4 Kbytes" probably means 4096 bytes. (It could also be 4000 bytes, depending on how "K" is to be interpreted) Thus, there are (4,294,697,296)/(4096) = 1048756 total page table entries. Since each entry requires 4 bytes, the total space required for the table is 4,194,304 bytes. - SigmaEpsilonΣΕ 03:37, 3 April 2008 (UTC)[reply]
This is computer memory we're talking about. In that context, the "K" suffix always means kilobytes of 1024 bytes -- not even marketing departments have dared to try to change it. --Carnildo (talk) 19:14, 3 April 2008 (UTC)[reply]

proxy

wat is a proxy website? and how can i get to one? —Preceding unsigned comment added by 76.14.124.175 (talk) 04:22, 3 April 2008 (UTC)[reply]

A proxy server is a server that makes requests on behalf of a user. Instead of the user connecting directly to a server, a proxy server will act as a 'middleman'. Check the wikilink for more in-depth detail. That's just a quick definition. And as for using one, just Google 'list of proxy servers' or something along the lines of that. crassic![talk] 04:34, 3 April 2008 (UTC)[reply]
Your internet service provider most likely has a proxy server. To use proxy server, you insert the proxy server addres in your web browsers settings. For example on IE7, select Tools → Internet options → Connections tab → LAN settings (assuming you are using broadband connection). Your service provider has given you the instrunctions. Some service providers always route everyting through proxy regardless of your browser settings. --PauliKL (talk) 23:19, 4 April 2008 (UTC)[reply]

TCS

wat is TCS??????? —Preceding unsigned comment added by 61.17.179.157 (talk) 05:00, 3 April 2008 (UTC)[reply]

Assuming this is unrelated to the proxy question, I've added a header for it. We have a list of possibilities right there: TCS. --tcsetattr (talk / contribs) 05:48, 3 April 2008 (UTC) (although my username starts with "tcs", it's not part of the answer. that's just a signature)[reply]

encode as base64 in html

Is it possible to store an mp3 file (or any file for that matter) inside the code of a HTML file as base64, and have it act like it were a real link to an mp3 file? Also, how can I store jpeg images in HTML files as base64? I have an encoder for base64. xxx User:Hyper Girl 12:27, 3 April 2008 (UTC)[reply]

GMAIL in html

Is there any way to get gmail into html format? Is there a classic gmail option? --Gary123 (talk) 12:33, 3 April 2008 (UTC)[reply]

Gmail has a basic mode. You can force it into this mode at [4] or [5]. The latter is the HTTPS one which is more secure if a little slower. x42bn6 Talk Mess 13:31, 3 April 2008 (UTC)[reply]

Movie on iPod

First, I'll get the basic facts out of the way: I have a 8GB 3rd gen nano iPod, a Dell PC, and the latest version of iTunes with all the bells and whistles. (Last time I asked a question here I was told that telling you that sort of stuff was useful.) So here's my problem. I had a video in mpg format, because that's what plays on Windows Media Player, which I usually watch the video on. But I wanted to put it on my iPod, and it said it didn't recognize the format. Then I right clicked on the video icon and noticed a handy-dandy feature that says "convert for iPod." So I did, and then my iPod accepted it, but somewhere along the way, it lost all sound and I'm only getting the picture. I found nothing useful on Apple Support. Any ideas? Thank you! Cherry Red Toenails (talk) 12:38, 3 April 2008 (UTC)[reply]

Try using a 3rd party converter. I myself use Videora iPod Converter which is free and pretty simple to use.TheGreatZorko (talk) 14:13, 3 April 2008 (UTC)[reply]

Thank you so much! It worked perfectly!!! Cherry Red Toenails (talk) 17:38, 3 April 2008 (UTC)[reply]

Why laptops wide only?

Why have all the bad ass PC manufacturers stopped producing normal non-wide screen laptops? I have searched websites and called customer cares of all PC companies and all of them say NO. Is it because Vista supports only wide screen? —Preceding unsigned comment added by 59.92.114.92 (talk) 13:33, 3 April 2008 (UTC)[reply]

It's because stupid people buy that crap. Vista, and everything, works fine with 4:3. Buy an external 16:9 monitor if you just have to have your movies. :D\=< (talk) 13:35, 3 April 2008 (UTC)[reply]
It is all about money. Consider a laptop with a 21" screen. If it is 16:9, the 21" screen will be 18.3"x10.3" for a total area of 188.5". If it is 4:3, the screen will be 16.8"x12.6" for a total area of 211.68". They charge more for the widescreen laptops while producing over 23 square inches less of LCDs for the screen. The people buying the laptops get the warm fuzzy "I got a widescreen" feeling and the manufacturers make more money. Everybody wins. -- kainaw 14:01, 3 April 2008 (UTC)[reply]

I don't see why you wouldn't want widescreen anyway. It allows you to view two pages of A4 side by side, allows for more peripheral vision in games, means less black space in movies. By the way most non widescreen monitors are 5:4 now, which is even less horizontal space. TheGreatZorko (talk) 14:12, 3 April 2008 (UTC)[reply]

Do games actually use the widescreen space to show you a range that you wouldn't have already been able to see? I just figured it would be stretched or something. Do the programs have to calculate your screen size and decide how much world to show you? — Sam 14:46, 3 April 2008 (UTC) —Preceding unsigned comment added by 63.138.152.238 (talk)
No, they do NOT. In the few games that went insane and decided to support widescreen resolutions, you have the same horizontal view angle and it just cuts off the top and bottom of your view. :D\=< (talk) 15:07, 3 April 2008 (UTC)[reply]
Incorrect. Froth(:D\=<) is being misleading again. Most modern games (not just the ones that 'went insane') support widescreen. Quick experimentation shows that they do it both ways. Portal, Halflife 2, and other Source games give you a wider horizontal field of view while keeping your vertical constant. (Exactly like Froth said they wouldn't do.) Screenshots here. Bioshock does it the other way. Bioshock appears to keep your horizontal field of view constant while adjusting your vertical field of view. (Like Froth said.) Screenshots here. This is not unique to games. Both techniques are used when releasing movies in different aspect ratios, although I'm not sure which is more common. APL (talk) 22:53, 3 April 2008 (UTC)[reply]
Well there are to things in this, first is that user must see different area depending on aspect ratio, but they shouldn't have unfair advantage because of this, that said, most FPS have more or less flat maps, so seeing more in top or botton isn't big advantage compared to seeing more in sides. Also if game is rendered in 1280 horizontal resolution for example is much easier to simply crop top and bottom, and also it's correct way to do this, because if they scale, then wide and non wide monitors with same dpi will have different picture sizes. —Preceding unsigned comment added by 195.238.64.156 (talk) 10:38, 5 April 2008 (UTC)[reply]
Besides, whoever said that having a narrower field of view with greater detail is bad? -- Meni Rosenfeld (talk) 23:15, 3 April 2008 (UTC)[reply]
Widescreen is where things are going. Don't resist.. in every case I know of, once a person has gotten used to it, they like it and wouldn't want to change back. Friday (talk) 14:47, 3 April 2008 (UTC)[reply]
Resistance is futile, you WILL be assimilated. StuRat (talk) 16:26, 3 April 2008 (UTC)[reply]
It really depends on usage. I prefer 3 4:3 monitors. However, I am a developer, so my usage is abnormal. For the average user, a widescreen is fine. -- kainaw 15:31, 3 April 2008 (UTC)[reply]
My friend bought one of those wide-screen laptops and the video card doesn't even support any wide-screen resolutions. I set it to put black bars on the side and he is quite happy that his image isn't horribly stretched. This is a fairly new laptop, mind you. I know that my recent Thinkpad has a normal screen, so I'd look to Thinkpads if I wanted no widescreen. All widescreen does is make the whole thing larger and more power-hungry with no advantage at all. 206.252.74.48 (talk) 16:04, 3 April 2008 (UTC)[reply]
Personally, I don't mind widescreen TV's, but I prefer my computer monitors to be "fullscreen" or whatever it's called. I guess that's why I only have a 17" monitor (but my TV is 61"). Useight (talk) 16:15, 3 April 2008 (UTC)[reply]

I, myself, do graphic designing and page lay out work and have been somewhat unsatisfied with my new widescreen laptop. The extra width isn't worth the loss of extra height. There are many situations that I find I have too much width and not enough height. Acceptable (talk) 22:12, 3 April 2008 (UTC)[reply]

One Query here:- I mostly spend time in browsers like firefox because I use PC for net only. Even if I use widescreen, I can use some sidebars which take some space and make firefox window a 3:4 one. But even if I do that, I think my browser user agent will say my laptop is widescreen and all websites will send to my PC, pages designed for widescreen and it will be horrible horizontal scrolling which I should do. Is there any way where we can change useragent info or do some thing else so that all webpages viewed be displayed in 3:4 size after adjusting firefox window to 3:4 ? —Preceding unsigned comment added by 59.96.136.58 (talk) 06:48, 4 April 2008 (UTC)[reply]

Your user agent doesn't tell your screen resolution- you're fine. And good job not browsing the internet widescreen; I think it looks terrible and keep the viewing area of my browser strictly at 5:4. :D\=< (talk) 18:55, 4 April 2008 (UTC)[reply]
There are no web pages designed for widescreen. However, some poorly made web pages do read the screen resolution from browser and adjust the width of page to the width of screen. Which is wrong, of course.
Web browsing is one of the applications where wide screen display is no good. After all, most web pages are taller in vertical direction than horisontal direction. That is true with most text documents, too. Watching movies is about the only use where wide screen is usefull. For example photos usually are 3:4 or 4:5 shape. And many photos are taken in portrait mode so wide screen is much worse than normal screen. Unfortunately wide screen monitors have become common as desktop monitors, too. If I were to buy a monitor now, I would buy a 3:4 monitor with pivot function for viewing portrait photos. --PauliKL (talk) 23:48, 4 April 2008 (UTC)[reply]
Hopefully you mean a 4:3 monitor o_o :D\=< (talk) 01:43, 5 April 2008 (UTC)[reply]
If the monitor has pivot function, the screen can be turned 90 degrees, so you can use it in landskape mode (4:3) or portrait mode (3:4). --PauliKL (talk) 11:42, 5 April 2008 (UTC)[reply]
Wait, you're sugesting that a web site should stubornly keep it's layout fixed as though it were a piece of paper and not respond to the user resizing the browser window? Or are you saying that some websites adjust themselves to screen size regardless of whether the window is maximized or not? If the later, can you give an example? If the former, I'd just like to say that I think you're crazy. APL (talk) 16:02, 5 April 2008 (UTC)[reply]
I came across some Javascript a long time ago to let you redirect according to screen resolution. I only used it for serving wallpaper images, though :p Rawling4851 18:33, 5 April 2008 (UTC)[reply]
@APL, even a non-widescreen screen at 1280px is too wide to be reading text in really, websites should have a limit to how far they stretch the main text area horizontally. --Random832 (contribs) 14:40, 9 April 2008 (UTC)[reply]

Detecting peripherals?

How does an operating system detect peripheral devices on x86 computer? It might be my limited English but I haven't found anything with Google. --212.149.216.233 (talk) 14:54, 3 April 2008 (UTC)[reply]

It really depends on what type of device and interface your are talking about. There is some information in ISA Plug and Play and links to many other specific technologies from there. --LarryMac | Talk 15:15, 3 April 2008 (UTC)[reply]
For the most part, the OS just checks all the connections. For example, is there something on the fourth USB connector? The OS checks to see if anything responds on that connector. If so, something is there. If not, nothing is there. Much of it is handled by polling devices to see if there is a change. This is not limited to peripherals. Removable disks are often polled as well. -- kainaw 15:30, 3 April 2008 (UTC)[reply]

Modern peripherals all have some sort of "Configuration space" that describes, in pretty plain terms, what the peripheral is. The exact protocol varies but, for example, on the PCIbus, there's a specific set of device registers that every valid PCIbus device has to have, and these registers tell you things such as the manufacturer of the device and the specific device type. So using those registers, the CPU can identify all the different devices attached to its PCIbus. Then, one of those PCIbus devices may include (say) an ATA bus disk adapter. So the software reaches out through the PCIbus to the ATA bus and asks around of all the disk-like devices connected to the ATA Bus. Same thing for the various USB and FireWire/IEEE 1394 busses. Eventually, after it has "walked the tree" of all of the possible busses and bus adapters and peripheral devices, the software is able to "size" your entire hardware configuration. And announce that you need to download some more drivers ;-).

Compare digital converter boxes with analog pass-through

My goal is to get a chart that lists all the attributes of those digital-to-analog TV converter boxes which support analog pass-through (hopefully with customer reviews of those of the 7 which are in stores now) for comparison, but I've had no luck. The seven which support analog pass-through and are FCC-coupon-eligible are:

Echostar TR-40 (not yet available)
Philco TB100HH9
Philco TB150HH9
RCA DTA800B1
Digital Stream DSP7700T
Digital Stream DX8700
Magnavox TB-100MG9

Any help would be much appreciated. StuRat (talk) 16:09, 3 April 2008 (UTC)[reply]

Widget/Application for a (intel powered) Macbook that will 'monitor' bandwidth usage

Hi,

I have 'mobile broadband' which I buy pay-as-you-go bandwidth for (1gb, 3gb or 5). I've tried to find a program/widget that will monitor my usage so that I can see how much i've downloaded/upload (or combined) so I can track how much my 'sessions' are taking up of my voucher. Does anybody know where I could find a bandwidth monitor program (for free of course!!) that will do what I describe. Basically i don't really know how much 'browsing' a 1gb limit will give me. For reference I don't download anything (save for maybe 5 tracks a month off of iTunes) but I do do a lot of browsing of sites like Flickr and Digg - which often links to little web-videos/flash-intensive sites. Any help greatly appreciated. ny156uk (talk) 17:13, 3 April 2008 (UTC)[reply]

Well, you can track per-session usage with Activity Monitor pretty easily (under the "Network" tab), but I assume you want something that will work even after you've rebooted (e.g. remembers your bandwidth). (Actually, I'm not 100% sure that Activity Monitor resets when you reboot, but it must reset at some point.) --Captain Ref Desk (talk) 17:52, 3 April 2008 (UTC)[reply]
Cheers, unfortunately whilst that does a reasonable job i'm really hoping to find something I can 'reset' the counter on at will and then watch as my usage is tracked up. I have 1gb 'credit' at the minute and 30 days before it expires - I'm going to just use the internet in my 'normal' capacity and see how long that lasts - I may have to start buying the 3gb credit if I run out too quickly, but hopefully I won't!! Thanks for the input ny156uk (talk) 19:22, 3 April 2008 (UTC)[reply]

You can use NetMeter, it is a software used for seeing how much data used daily, monthly etc. website: readerror.gmxhome.de/

Moving pages

In HTML/PHP/HTTP, is there a way to move a page so that:

  • Googlebots (and other crawlers) know where it has moved (Location: /newpage)
  • User gets a "Page moved" notice AND is redirected automatically
  • The target URL is without /newpage?moved and such.

--grawity talk / PGP 17:42, 3 April 2008 (UTC)[reply]

If I use a GET parameter (if (isset($_GET['moved'])) displayNotice();) and do a 301 Moved Permanently redirect with Location: /newpage?moved, user can see a notice, but Googlebots get the incorrect new location (/newpage?moved instead of /newpage), which is also saved to bookmarks => user gets notice everytime. If I only do a redirect, user doesn't notice the redirect and a different URL, and doesn't update his bookmarks (the only way to come to the old page), it will once result in a dead link when I remove the redirect (old page). If I don't redirect, and put the notice to the old page, Googlebots won't know it has moved.

Ideas? --grawity talk / PGP 17:48, 3 April 2008 (UTC)[reply]

What if you used the PHP to check the UserAgent, give it a Location: header if it is not a browser, and serve up a META REFRESH if it is a browser? There'd be a few obscure browsers and bots that would slip through the cracks but I don't think they'd amount to much. In any case, using the UserAgent might be a decent way to distinguish between what you serve to bots and to humans, even though it is not infallible. --Captain Ref Desk (talk) 17:48, 3 April 2008 (UTC)[reply]
What is the problem? The normal way to move a page is as follows:
  1. Store the pages at the new location.
  2. Remove the pages from old location and replace them with a short page that contains text such as "Page has moved, please update your link/bookmark" and a link to the new page. Do not use any redirect.
A user who uses old bookmark sees this message, cliks on the link and then stores the new location as bookmark. Bot will automatically follow the link and index the new pages.

scandisk/defragment problem

I'm running Windows Me. Firstly, my computer is working OK, though it's a bit old, I want to make sure it's healthy so it doesn't die on me.

Now, Disk Defragmenter (Windows) won't work because it says the hard disk is damaged. It says to use scandisk to fix the error.

Scandisk won't work, it gets to two blips or so and then starts again, and gets stuck in an infinite loop in which it tries and tries but gets not very far at all. It does this in full and lite versions of scandisk. It does this even if I deliberately don't switch it off properly so it goes to scandisk at startup.

Firstly, should I be particularly worried about my disk being damaged?

Secondly, given options:

Yes, you should be worried. It seems that the disk is indeed damaged; if you value your data (and time) at all, you should immediately back the data up by whatever means you can. Damaged hard disks tend to go downhill fast, and you may not have many reboots left in it before it goes altogether and your data is lost. If you're just keeping this old machine around for sentimental/museum type purposes, you might (after the backup) reformat the disk and reinstall ME. -- Finlay McWalter | Talk 20:11, 3 April 2008 (UTC)[reply]
I get something similar in Windows 98. The "damage" never seems to be anything much, and it keeps restarting because it says "Disk contents have changed". If you watch it like a hawk, you might see that message flash at the bottom of the screen briefly when it restarts. DSL seems to be the culprit in my case. It periodically changes the hard drive contents, even when not actively in use, because it's "always on" (it's selling point). Apparently it feels the need to log that it did a handshake to the server or some such nonsense, which stops the defrag or scandisk cold. I could pull the DSL cable out, but have opted to stop the defrags instead, since I have plenty of open disk space, and defrags really are only needed when disk space is low. StuRat (talk) 20:54, 3 April 2008 (UTC)[reply]
I read IANAD's case correctly, the scandisk hangs even in the boottime scandisk run - in this case only scandisk is running (the internet stuff and various 3rd party progs haven't started yet). That "disk contents have changed" thing really can't happen in then, and so a failure (or hang) is indicative of significant problems. -- Finlay McWalter | Talk 21:01, 3 April 2008 (UTC)[reply]

Yeah, it's not got Internet access (I'm using a different machine to speak to you), so it's not that. There is a really old virus scanner running in the background. I wanted to defrag because I'm running out of space, and also am thinking of installing Linux on it as well as Windoze. I'll make sure I copy all my important files over to somewhere, then have a think about it. Possibly buy a new hard drive anyway, but reinstalling windows could be interesting (though I might not bother and just use Linux, if I can get my head round that). —Preceding unsigned comment added by I am not a dog (talkcontribs) 21:14, 3 April 2008 (UTC)[reply]

There could be any number of things happening that cause scan disk to think the disc contents have changed and start all over. I've had that problem before with a drive C. Take that drive out. Put it in a second computer as drive D and scan disk and defrag it on that PC. I cannot think of a time that has not worked. But, it does mean finding a second PC and knowing how to put a second drive in a PC. It's very easy, but I could see how it would be a little scarry if you've never done it before. If you have a second PC and need to know how to make a primary drive a secondary drive on another PC, let us know.--Wonderley (talk) 21:31, 3 April 2008 (UTC)[reply]

I'd be OK with taking it apart (done that before). I also have a spare machine (this one) which ought to have a slot (though my Dad might grumble). Is there anything else I have to do other than plug it in? —Preceding unsigned comment added by I am not a dog (talkcontribs) 21:47, 3 April 2008 (UTC)[reply]

If the computer has a recent BIOS, then just plugging in the hard disk correctly should do the job. On an older machine, you may need to hit Escape or Del or some other key as it boots to get to a setup screen, and use the setup screen to tell it that it has a new hard drive. rspeer / ɹəədsɹ 22:19, 3 April 2008 (UTC)[reply]
Yes you can put the faulty disk in another computer, but if they are on the same cable you might have to change the jumper settings on the back of both disk drive units. When you take the machines apart, take a look at the back of the disks and you will see a collection of 6 or 8 pins with a small jumper plug joining two of the pins. Somewhere on the drive casing, there should be a diagram of these pins, or maybe next to the pins there is some small text in the plastic. The faulty drive should be identified as "slave" (sometimes "SL") and the main drive as "master" (sometimes "MA"). This is done by moving the jumper to the approprite pair of pins.
It's all fresh in my mind, because only yesterday I canibalised my two old WinMe machines (one with a faulty drive) to make one good one dual-booting WinMe and Linux.
Small world eh? Astronaut (talk) 23:00, 3 April 2008 (UTC)[reply]

Astronaut is correct. CS - Cable select is also an option on the jumpers. If you look at the ribbon cable you will see a notch in it that cuts into one of the wires. That is how the drive can also tell which one it is. However, selecting the master (AKA Primary) and slave (AKA secondary with jumpers) is the one way you can be assured it's set up right. But, if the PC you are using now is currently set to CS, you'll have to change it's jumpers too.
Don't be worried. It's not that big of a deal. The safeest way to do this is:

- IMPORTANT! Every time you start to touch the PC, touch the metal chassis of the PC first so that you do not have static electricity burn something up.
- Power off your PC. Get the make and model numbers off of the drive itself. Look at the jumpers and see if it make sense. Make a note of how it is now and what cable it is plugged into. The ribbon cable for the drive has two jacks for drives.
- With it all together, look online for documentation on your drive and print it out. That's not necessary in but it might make you and your dad feel better.
- OK, power off again and with just your good drive C have the jumpers set to Master (primary) and power up. Your PC should work just like it was. That should make you feel better.
- Now power off and add the second drive (the one you want to fix) with the jumpers set to Slave as a slave (secondary) drive. Tada, Power on, and it's drive D.
-If at any point something doesn't work, power off and go back to the previous step. If you do something like have a secondary drive set as a primary drive, or have both drives as primary, it's no big deal. The worst that happens is that the PC does not boot up. Put it back like it was and it's back working.
- Static electricity is only way I can think that you might damage something.
- This may work out well for you. Knowing how to do this can help with outher prolems and hard drive upgrades. I move drives around all the time. PCs for some reason tend to come set up as cable select. I set the jumpers myself. I have had brand name drives not work right when set to cable select.

Wikipedia's CSS

Anyone know precisely how to duplicate Wikipedia's font and font size on my own website? The .css files are insanely complex.... Evercat (talk) 23:18, 3 April 2008 (UTC)[reply]

Wikipedia simply uses sans-serif, which defaults to whatever your browser is defined to use (usually 12pt Arial, I think). It doesn't define a specific font. x42bn6 Talk Mess 05:40, 4 April 2008 (UTC)[reply]

C++ classes: supporting padding and preserving stream state

In C++, if I wish to print an integer width padding, I use cout << setw(10) << i;. If I have a class whose printed representation should be "*42*" (for some value of 42), how do I write its insertion operator overload such that I may write cout << setw(10) << obj; and get (for a two-digit number like 42) only 6 spaces of padding instead of 9? Moreover, how do I handle cout << left << setw(10) << obj;, which would tend to put the padding after the first asterisk? I could hack something together with an ostringstream, but I suspect there's a better answer. Perhaps it's somehow related to another question: what is the best way to restore a stream's state if, within an insertion function, one needs to, say, specify a radix for a sub-insertion? --Tardis (talk) 05:43, 4 April 2008 (UTC)[reply]

For restoring a stream's state, try this Boost library. You might also be interested in Boost Format, which combines the type safety and extensibility of iostreams with the doesn't-suck of printf formatting specifications. --Sean 12:46, 4 April 2008 (UTC)[reply]
Thanks -- Boost is awesome, isn't it? I (am fortunate to) rarely need precise output formatting, so I tend to design my entire IO formats based on "what iostream does with the least effort on my part". In other work, that might be a sadly insufficient choice, so I'm glad to have iomanip de-spookified that way. Moreover, I suppose my original question has been answered: if what boost::format does with a width is print to a string and then print the string with the width (though see more advanced width-processing in their Rational example), then surely that's the best I can do! Proof otherwise is nonetheless invited. --Tardis (talk) 13:51, 4 April 2008 (UTC)[reply]

Low-resource firewall for XP

I'm currently installing windows XP on my MacBook, since I'm going to visit the DreamHack computer festival later this year.

Black and white photographs

Can black and white photographs or old film can be converted into color? For example by a computer algorithm which detects different shades of gray and converts them to their associated color. xxx User:Hyper Girl 15:30, 4 April 2008 (UTC)[reply]

There's no automatic way to do this. A certain shade of red and another certain shade of blue, for example, will be the exact same shade of gray in a B&W photo. You can't "back out" that color information, because it just ain't there. It can be done manually, as described in Film colorization, pretty much the same as coloring in a line drawing in a coloring book. Some technological automation exists to help speed the process along if there are multiple frames, as in a movie. jeffjon (talk) 16:12, 4 April 2008 (UTC)[reply]
In the old days, it was done by hand-tinting/hand-colouring the prints.
Atlant (talk) 16:46, 4 April 2008 (UTC)[reply]
There was also a brilliant photographer is Tsarist Russia who took three greyscale (what people mistakenly call "black and white") photos of each scene, one with a red filter, one with a green filter, and one with a blue filter. He reasoned that the three pictures could one day be combined into full color pics, which we have now done. Thus we have wonderful full color pics of Tsarist Russia: [6],[7]. Had an American thought of this approach, we might now have color pics of the Civil War and Abraham Lincoln. The only limitation of this method was that movement between when the three pics were taken would mess up the color, as in the girl in the lower left corner of this pic who apparently moved her head: [8]. StuRat (talk) 18:03, 4 April 2008 (UTC)[reply]
Well, plenty of others knew that you could take monochrome photographs with lenses to capture different color channels (this approach goes back to the 1850s). The problem is combining them into a permanent photograph, and even our Russian friend Prokudin-Gorsky couldn't do that. The full-color photos of Tsarist Russia we have today are modernly produced from his negatives; he never saw them printed in color. --Captain Ref Desk (talk) 22:24, 4 April 2008 (UTC)[reply]

c# what is it?

So is c# typically compiled or bytecoded->interpreted like Java? —Preceding unsigned comment added by 194.223.156.1 (talk) 16:27, 4 April 2008 (UTC)[reply]

C# runs on a "common language runtime", which would be equivalent to the Java Virtual Machine, it's interpreted. --LarryMac | Talk 17:20, 4 April 2008 (UTC)[reply]
No, that doesn't mean it's interpreted, nor is Java interpreted either. The CLR-bytecode format, like the JVI-bytecode format, is just an intermediate language; prior to execution (and, increasingly, during execution too) that IL is translated into native machine language. Java, at least on desktop and server platforms, hasn't been interpreted for nearly a decade; C#, Java's kissing cousin, never has been. -- Finlay McWalter | Talk 17:56, 4 April 2008 (UTC)[reply]
Calling Java (and C#) "bytecode-interpreted" is mostly accurate. A major complaint about Java is that you cannot compile your code to a standalone executable. You compile to get a "class" file which requires the Java Virtual Machine to run. C# compiles to an "exe" file, which gives the impression that it creates a standalone executable. Unfortunately, this is just a nasty trick. The exe produces is not a standalone executable. It requires C#'s virtual machine to run. Neither language (without third-party tools) compiles to a standalone executable file. As such, it is not possible to compile a program and send it to someone who does not have the virtual machine and expect them to run it. For some unknown reason, the Java and C# developers feel that standalone executables are a relic of the past and that everyone is eager to install a wide variety of virtual machines on their home computers. -- kainaw 18:01, 4 April 2008 (UTC)[reply]
The questioner asked about whether the language is "bytecode interpreted", not about linking. Calling either C# or Java interpreted is not "mostly accurate", it's utterly false. Being dependent on external code does not make something interpreted. Not being compiled into an executable is not the same as being interpreted. A translator is not an interpreter, and neither is a dynamic translator. The term "bytecode interpreter" has a specific meaning, that the intermediate language is interpreted opcode by opcode by a software loop. C# is not bytecode interpreted, nor is Java. -- Finlay McWalter | Talk 18:18, 4 April 2008 (UTC)[reply]
Actually, Java was originally implemented as byte code interpreted language. Later, JOT (Just On Time) compilers were developed that compile the byte code into machine code before executing the program. However, there is nothing in Java or C# language that would require using byte code. They can be compiled directly into native machine code just like any other language.
Java and C# do not need any virtual machine if compiled into native code. However, they do need the runtime library. The idea with runtime library is that there is no need to link the same routines again and again with every application. Of course technically it would be possible to link the whole .NET library with your .exe file, but then the exe file size would be at least several tens of megabytes.

to anyone who has worked with adobe acrobat: create a script to un-blank a form?

I am using Adobe Acrobat to create forms with interactive scripting in the forms.

I want my users to click a button before starting a form. The button is just their way of saying they agree to my terms and conditions before filling out the form.

Is there a way to make it so the pdf form looks completely blank every time they open the pdf, and stays blank until they click the "I Agree" button?

Thanks for any info NoClutter (talk) 21:00, 4 April 2008 (UTC).[reply]

I know this sounds low tech but what about a check box at the top of the form saying "I agree that by filling this form I am <list here>" ? Even better would be a small check box saying "Please read the pages 365-396 and mark your option in one of the the check boxes above. You must agree to fill this form." just below the header in page 1 of the form. However, I am pretty sure that what you want can also be done. Which version of Adobe Acrobat are you using?

@Froth Frankly it is ridiculous, annoying too. I don't have authority on the operations though, I'm just the button-pressing IT guy that does what they tell me to do. So yeah, it sucks, but I gotta deal with it.
@Kushal Acrobat 7.x. The checkbox is considered by the higher-ups to be an unacceptable solution because there's other stuff that gets put inside the PDF contingent upon them pressing the "magic button". In other words, they just want that button pressed before *any* interaction with the form is possible at all ... and they want that *every* time someone opens the pdf. NoClutter (talk) 22:17, 4 April 2008 (UTC)[reply]
The higher-ups need to talk to the lawyers. Not legal advice, but my layman understanding is that they just need to include legal text that "by filling out and submitting this form you agree to..." The technical rigamarole will just make the PDF more difficult for your end-users, some of which might not have a version of Acrobat that could handle the button anyway. I say, kick it back up to them as a legal issue, not a technical one. -- Kesh (talk) 02:53, 5 April 2008 (UTC)[reply]
Kesh, I don't know if "they" would be willing to talk about usability, much less legalese with IT. What you say makes a lot of sense. It seems plausible to divide the form up to two parts and hand the second part only when they are have "correctly" filled the first part. However, NoClutter does not seem to have much say in it. NoClutter, is there possiblity of a form on a webpage? (That would be really helpful. However, I doubt it.) NoClutter, if it is possible to do what Kesh says without risking yourself, please do so. Or try to push for a two part pdf solution. If the the participation in this form is not very big, it could even be manual. Kushal 13:35, 5 April 2008 (UTC)[reply]

Don't click "Safely remove hardware", then the pen drive should be there in My Computer. If you clicked the "Safely remove hardware" first, then Windows will have disconnected the pen drive from the system so it can be physically removed from the USB port without loss of data.
Once, you have finished moving the files to/from the pen drive, now is the time to click "Safely remove hardware" (remembering to wait for the acknowledgement message), and physically unplug it from the USB port. Astronaut (talk) 11:35, 5 April 2008 (UTC)[reply]

I'd be shocked if it was your graphics card warming up. I suspect it is services and programs that turn on at startup that are slowing your PC at first. When they are done - tada, faster PC.

It's possible that your computer is taking a while to get things like disk caching, virtual memory, and graphics buffering sorted out -- your computer can't magically know what parts of what programs need to be kept in memory or what files you're going to open.

My guess is that you have "automatic updates" turned on. This means that each time you start up your computer it goes online and looks for updates for your software. If it finds them, it downloads them and installs them. This could take half an hour, especially if you have a slow DSL connection or, God-forbid, dial-up.

There is a good comparison table at Data compression#Comparative. D0762 (talk) 19:09, 5 April 2008 (UTC)[reply]
As extreme cases, a 938MB empty file can be compressed down to a kilobyte or two, while 938MB of cryptographic-quality random numbers will be slightly larger after compression. --12.169.167.154 (talk) 22:34, 5 April 2008 (UTC)[reply]

Wireless weirdness

I have a Netgear MR814v3 wireless router. It has worked great for about two years now, never any problems with it.

Last week or so it started acting up, though. On both my MacBook and my wife's iBook, the wireless signal will go from connected to disconnected to connected to disconnected fairly rapidly (switching states one a second or so) for no apparent reason. It's not an issue of signal strength, I'm sitting right next to it. The internet connection from the cable modem seems fine. It's the router itself that seems to be doing weird cycling issues. After it does this for about 20 seconds then it usually connects just fine again.

The router has the latest firmware, and I even did a full reset to factory defaults and reconfigured it. Same problem. I tried changing its channel, that didn't seem to help either (though I've just tried changing it again, having made sure that there is no one around using one the same channel). I haven't otherwise really changed the settings with the router or the two computers.

Any idea what is causing the mishaps? It's a weird problem. The router uses WPA Personal security. The fact that the issue happens on both computers makes it look distinctly like a problem with the router. Blah. --Captain Ref Desk (talk) 18:15, 5 April 2008 (UTC)[reply]

After two years, maybe the hardware is simply broken from heat stress (those wireless cards get very hot with constant use). I advise you get a friend to test the connection with their laptop and a different wireless card, to see if the problem is the card or the router. D0762 (talk) 19:06, 5 April 2008 (UTC)[reply]
Well, as I said, I've tried it with two different computers (which are different ages and models), so I don't think it's a problem with the machines. --Captain Ref Desk (talk) 19:21, 5 April 2008 (UTC)[reply]
Then it looks like something is up with your router. What, I can't say. D0762 (talk) 19:25, 5 April 2008 (UTC)[reply]
Yeah, I think the routers just burned out after two years. Plunk down the sixty bucks for a new one (and if you're a badass you can do this thing) --Oskar 18:41, 6 April 2008 (UTC)[reply]
Yes, firmware replacements are something to look at. Though I want to note, I have a Buffalo WHR-HP-G54 and I've found the Tomato firmware to be far more stable than DD-WRT. And the interface is nice too. OpenWrt is the other popular option. -- Consumed Crustacean (talk) 04:02, 7 April 2008 (UTC)[reply]

generating words in a pattern

I want to generate a set of names that all follow a certain linguistic pattern. There are five possible "slots" for a letter, and severl possible letters that can go in each. The first slot can contain G,Q,C,H or no letter. The second can contain A,E,I,O,U or no letter. The third can contain R,L,W or M. The fourth is the same as the second. The fifth can contain M,N,R or no letter. What I want to know is am I looking at an impossible or a workable number of possible combinations? And if the number is large, is there a way of getting a computer to generate them for me instead of doing them by hand? My computer programming knowledge level is zero. But I do have a computer :) (P.S. there are a couple of additional constraints, such as single-letter names and names without a vowel are disallowed, and that neither Q nor W should be adjacent to I. But I suspect that might make it really far too complicated.) Thanks for any advice. 65.92.188.177 (talk) 21:14, 5 April 2008 (UTC)[reply]

The number of possible combinations is easy to calculate. It's 5*6*4*6*4 = 2,880. Writing code to create this list is easy, but not if you aren't a programmer. Do you have Excel. Office Excel, not the Excel that comes with MS works? Making the code to create a spreadsheet with the list of "words" wouldn't be too hard. I could maybe give you somethign to cut and past into a macro.--Wonderley (talk) 22:17, 5 April 2008 (UTC)[reply]

Thank you very much. I do have Office with Excel. I don't know what a macro is, though. But 2,880 might not be too bad. I was afraid it'd be far more. Let me know if the macro thing is easy to explain? 65.92.188.177 (talk) 22:57, 5 April 2008 (UTC)[reply]

Currently working on it. Almost done. It won't be too bad.--Wonderley (talk) 23:03, 5 April 2008 (UTC)[reply]

OK, here it is. Rather than talk you through the cutting and pasting, I put the spreadsheet on my web site: http://wonderley.com/misc/wikipuzzle.xls
Once you get rid of 1 character words, words without vowels and words with "QI", "WI" or "IW" ("IQ" is not possible) the list drops to 2508. I'll go ahead and post this and just for those who might be interested, I'll make another post with the macro.

This is like a text-book example of showing the awesomeness that is Prolog:
first(A) :- A = ''; A = 'G'; A = 'Q'; A = 'C'; A = 'H'.
second(A) :- A = ''; A = 'A'; A = 'E'; A = 'I'; A = 'O'; A = 'U'.
third(A) :- A = 'R'; A = 'L'; A = 'W'; A = 'M'.
fourth(A) :- second(A).
fifth(A) :- A = ''; A = 'M'; A = 'N'; A = 'R'.

word([A,B,C,D,E]) :- first(A), second(B), third(C), fourth(D), fifth(E), 
                     \+ (B = '', D = ''), \+ (A = 'Q', B = 'I'), 
                     \+ ((B = 'I'; D = 'I'), C = 'W').

Just define the constraints and then let prolog do the rest. Note that I didn't include the "more than one letter long" constraint because it is equal to the "has to have a vowel constraint" (that is, they are both equal to "letter number 2 and 4 can't both be empty"). I love prolog, it's a shame that you can't use it to do anything sensible :) --Oskar 18:19, 6 April 2008 (UTC)[reply]

And if you have any newer shell than Bourne, brace expansion will help with the looping:

 echo $w
done | egrep -v 'I[QW]|[QW]I' | grep '[AEIOU]'
(In zsh it can actually be a one-liner: print -l {G,Q,C,H,}...|grep...)
Oh and since nobody else has mentioned it: the root operation here is a Cartesian product of the 5 sets of options. Knowing that terminology may help in the search for other methods. --tcsetattr (talk / contribs) 21:08, 6 April 2008 (UTC)[reply]

Overloaded servers damaged?

From the home page of an iGoogle widget application thing:

Sorry, guys. We had hardware problems at the start of 2008. Heavy loads (we are almost at 80,000 notepads) plus burnt out hardware meant nightly crashes. We've replaced the entire server. Brand new, dedicated hardware. We should be reliable from here on out until we hit about 50 times the current load... Again, sorry for anyone who feels like they were burned by recent server outtages. This is an independent project that has destroyed two servers already and generates a gig of log files for a week of activity, and we never promised it would be smooth... Until now.

How can server overloading lead to damage? I'd have imagined that a properly cooled system (even an improperly cooled one should shut down to spare itself from damage, right?) would yield poor service but not burn out. ----Seans Potato Business 13:59, 6 April 2008 (UTC)[reply]

You're right to be suspicious, but the story's not completely implausible. Overheating could certainly lead to the described nightly crashes, if not to irreversible "burnout". Long-term overheating will certainly lead to premature ageing. Even if the processor shuts itself down due to overheating, if it's operating in an improperly-cooled environment full of other heat sources, it could stay overheated. Finally, there are almost certainly cheap systems out there that don't even try to shut themselves down. —Steve Summit (talk) 17:07, 6 April 2008 (UTC)[reply]
It does sound a little suspicious, but it's not totally out of the realm of possibility. One thing I can imagine happening is that they used cheap hard-drives and put a LOT of load on them. Then they'd burn out pretty quickly; on the other hand, hard-drives are trivial to replace (and if you RAID them properly, they shouldn't give to much downtime). I would say that it's equal parts the fault of the hardware and incompetent management. --Oskar 17:28, 6 April 2008 (UTC)[reply]

how to operate two Netware servers simultaneously

I have a Novell netware network consisting of 25 nodes. The Netware version is 4.12. The network has been established some 15 years ago. Since the server harddisk shows some problem I have decided to install a second server. My hardware vendor supplied a computer with pentium 4 processor and IDE hard disk(My first server is also a pentium 4 processor and SCSI hard disk. But there is little variance in processor speed) and installed Novell netware 4.12. But now the hardware vendor and software installer is of the opinion that the two servers cannot start simultaneously. We have to start the second server after logouting all the clients from the first server and then using a DOS BATCH program updating all the files in the second server from the first. My question is Is it not possible to start the two servers simultaneously and through a node we can ATTACH to either of the servers as desired.

You are asking which of two solutions -to two different problems- is "better". If you have a network with one server and a bunch of untrainable non-geeks, then minimising the amount of independent thought you force your users to do is best --> do the fail-over thing. Set up a 2nd server as similar to the first as you can, and, when the "old only server" crashes, have the users stand around doing nothing until you do the manual switchover as you described above. When the switchover is done, you bring up your "new only server" and have the users log in. Their universe has not changed, and they are happy. More work for the techs, but NO stress for the [l]users.
If, on the other hand, you have users who can accept new things, you can certainly add a second server, and make a PA announcement periodically that "SERVER ONE IS DOWN. YOUR FILES WILL BE ON DRIVE LETTER Q UNTIL WE FIX SERVER ONE." Easier for the techs, harder for the users. Of course, this assumes that you have a second license for Novell Netware 4.12 for your second server so that they will play nicely together..... -SandyJax (talk) 21:52, 7 April 2008 (UTC), an old CNA (Certified Novell Administrator)[reply]

Alternatively, you should be able to go to the tools/options window, in the content pane there should be an item about loading images automaticaly (this should be on) and a button to bring up the exceptions list to loading images.

Server Space vs Shared Hosting Space

Hello all.

  1. I'm looking at hosting. I already have shared hosting, but looking ahead to an optimistic future I was wondering something. Hostican has dedicated servers that cost more than shared hosting. This makes sense because you pay for control of the whole server. Yet on shared hosting you get more GB of space. How is this so? Is the shared hosting figure from multiple servers connected together? Is that seamless? Is it a lie?
  2. Are the limits on GB for servers the same/similar to those for a standard PC?
  3. How difficult is it to set up a server on your own, if you just buy the thing and connect it to the interent on your own, and what might the costs (rack, server(s), cables, software) for such an endeavor in general?
I don't know what I'm talking about:
  1. Renting your own server costs more. That's a given for obvious reasons. Having less space helps them keep the price down; as well, I'm sure they're betting on most shared users not using up 100% of their package, so there's a chance they oversell space (similar to what ISPs do with bandwidth).
  2. What limits? Hard drives are hard drives, though server drives tend to be more expensive/reliable and covered by backups and RAIDed.
  3. You need a computer. What type depends on your particular needs. And you may want to invest in RAID and such to keep the data safe (and downtime short). Plus you'll probably want an ISP that allows hosting (though many will tolerate it as long as your bandwidth usage isn't too high), and probably one that has decent uptime and decent upstream speeds. And then you'll want to set up something Linux or BSD or Solaris or (oh ffs don't) Windows Server based, which isn't too hard (and free for all but Windows, unless you specifically pay for support). For a lot of people, all of this isn't really worth the time and effort, though. There are also hosting companies that let you use your own machine, but who handle the ISP and networking stuff themselves, which can potentially save you money.
-- Consumed Crustacean (talk) 03:43, 7 April 2008 (UTC)[reply]
A rack of high-end blade servers will be way too expensive for your needs if you're currently on shared hosting. Also if you want a solid connection to an upstream ISP then you're going to be paying a lot. Hosting companies can afford it because they have lots of customers paying specifically for the bandwidth.. but you probably can't afford it. :D\=< (talk) 04:29, 7 April 2008 (UTC)[reply]

What is this, and how can I get rid of it?

For the least 60 days or so I have had this bar that appears on my computer when I am on line to inform me that "My computer may be infected", but when I originally went to the site that they suggested my anti-virus program warned my that my computer caught something. Since then I have steered away from the site, buyt can not get that damn bar off the internet explorer. Does anyone know what I can do to remove it? TomStar81 (Talk) 04:25, 7 April 2008 (UTC)[reply]

Run Ad-Aware, Windows Defender, and Spybot (yes, all three). Or reinstall the OS. -- Consumed Crustacean (talk) 04:39, 7 April 2008 (UTC)[reply]
And next time don't run malicious code. It's not hard. Honestly, I don't even understand how this happens to people. :D\=< (talk) 04:44, 7 April 2008 (UTC)[reply]
It is hard, if you want to have a high level of confidence that it won't happen. The problem is that all software, except perhaps the simplest, has undocumented behaviors. It is practically impossible for an ordinary user to know for sure whether the software he or she uses has exploitable bugs or configuration problems. Are you sure it is impossible to craft a piece of Flash content that can infect a computer? (Not to pick on Adobe, I'm just using Flash as an example of a complex and expressive format.) --71.162.241.83 (talk) 08:42, 7 April 2008 (UTC)[reply]
A very small portion of malware infections come from drive-by exploits in things like Flash. Most of it is bundled with shady software (usually laughably so), or comes through email attachments or the like. That's not to say that situations like that don't happen, but they're really not common, and patches are often pretty fast these days. It's really not that hard to avoid. People just need to learn how to properly assess the trustworthyness of software packages. Unfortunately a lot of people can't be bothered, or refuse to take responsibility for anything. -- Consumed Crustacean (talk) 08:51, 7 April 2008 (UTC)[reply]
Another helpful post from Froth (:D\=<). That'll be the last time TomStar goes to the malicious software store and buys some malicious code! Seriously, this can be more difficult than it seems, anyone who says differently does not understand the normal, everyday user. The user may be running an old version of IE with security holes large enough for drive-by spyware infections. But even ignoring that possibility, it's entirely possible that the user downloaded some seemingly innocuous software product like WeatherBug or Bonsai Buddy. Seeing the difference between these products, and completely legitimate free products, like Firefox or AdAware, is not easy for people not familiar with the software industry. It is extraordinarily unreasonable to blame the user for not being an expert not only in the maintenance and upkeep of a household appliance, but also in the industry that produced the appliance and its accessories.
I recommend using a spyware-checking software like AdAware and an anti-virus like AVG on a regular basis.
And do you recall the name of the site it tried to direct you to? I'm just curious. APL (talk) 13:55, 7 April 2008 (UTC)[reply]
It's perfectly reasonable to expect people to be responsible for the code they execute. If you're downloading innocuous-looking programs left and right without a better foundation of trust than "it looks ok", you're going to get burned. :D\=< (talk) 02:36, 8 April 2008 (UTC)[reply]
For you and I, perhaps. But most computer users are not willing to put more effort into maintaining their computer than they are into maintaining their microwave oven. These are the same people whose VCRs blinked "12:00", back when people had VCRs. Was it their fault their VCR's clock wasn't set? No, because the mechanism for setting the clock was often extremely ridiculous. Especially before on-screen setup became common. Sure, with enough time you could read the manual, or experiment for a while, and eventually overcome the ridiculous design, but why bother? The VCR's design was so crumby that the next time the power failed you'd be going through the same needlessly complicated, time wasting ritual. The same is true for computers. For me a computer is a vital tool of my trade. I make sure I know how to use it. But for most people, a computer is an appliance like a VCR or a blender. To blame these people because they're not dedicated enough to overcome the appliance's serious usability problems shows a lack of understanding of the situation. APL (talk) 13:50, 8 April 2008 (UTC)[reply]
APL, I must say that I agree with Froth. I agree with you on what to do next but we also need to keep in mind that prevention is better than cure. I know there is so much to be done about the interface and the "user experience" but that is not an excuse for sloppy work on the consumer's part. Kushal 00:17, 9 April 2008 (UTC)[reply]
All of that said, there are tones you can take with a user that are helpful, and tones that aren't. Taking a certain tone can reinforce an idea that people in the know about computers are utterly clueless when it comes to human interaction. Of course prevention is better than cure. Doctors still don't make yelling at people or calling them names part of their bedside manner - why do you suppose that is?

I teach math, and even though I think there's no excuse for making claims such as , I can't simply tell people that there's no excuse, and then say it's their responsibility to learn it. I mean, I can, but that would make me a bad teacher. I could say that "most students can't be bothered to take responsibility for anything," but would that make me a more effective teacher, or a more bitter one? Teach smart computer hygiene; teach prevention. Don't display incredulity or contempt for people who don't already know what you do. It's not about whether or not an "excuse" counts. It's about making things better, starting where we are now. -GTBacchus(talk) 00:26, 9 April 2008 (UTC)[reply]

That is closer to what I'm trying to get at, but to say that the solution is better education is just another way of blaming the user. The point is that the system requires an unreasonable amount of education. To most people a computer is a mundane appliance that makes up a minimal part of their life. I don't claim to have a solution to that, which is why stop-gap solutions like AdAware, etc are so valuable. Here is the key point : To suggest that there is an easy solution that the user has somehow missed or failed to learn is misleading and can lead to a lot of frustration. Better to admit that the amount of effort currently required for good 'computer hygiene' is unreasonable, and suggest alternatives like always active spyware/virus prevention software.

Leap-frogging OS

I saw in the news today that MS will offer XP for sale all the way through until the release of Windows 7. Basically, through the entire run of Vista. Is this the first time that a software manufacturer has offered software package A all the way through the time of software package B until the release of package C? I'm not really explaining this very well but I'm hoping that you can catch my drift... Dismas|(talk) 05:11, 7 April 2008 (UTC)[reply]

I am not sure how good Windows 7 will be if Marketing wants to get it out by 2009. I think it makes sense that Microsoft is selling Windows XP. There is little additional investment to make for XP. Some people dislike Vista. Some people have fears about Vista. I think it little matters to Microsoft if a few customers shy away from Vista to XP. The main point is that if Microsoft sells Windows XP and someone buys it, it is a sale for Microsoft and one more customer retained/enrolled. In all this humble mumble about Vista, we tend to forget that Microsoft is HUGE. Even if Vista was a total failure (which it is not), Microsoft can absorb it. If you talk about any "software manufacturer", I am sure there are plenty of other instances. You can still find Mozilla Firefox 0.9.3 here. Although I don't know if fits the bill as "Mozilla is not a traditional software company"[11].:I don't think everyone needs to upgrade to the latest software at once. I am running Tiger and I am not rushing to buy a new piece of software "just because it is there". If I need to upgrade it, or if it makes my life easier, surely I will upgrade. Leopard looks great but I don't know why I need it yet. I'd say it is the same with Microsoft products, too. Kushal 10:23, 7 April 2008 (UTC)[reply]
The question isn't one of need or want but of availability. I don't think Tiger is still being sold by Apple. Their only OS that is comercially available is Leopard. Dismas|(talk) 10:43, 7 April 2008 (UTC)[reply]
My bad. Sorry. Kushal 17:17, 8 April 2008 (UTC)[reply]
I don't have a cite, but I think microsoft continued to offer Win95 for a surprisingly long time after 98 came out. The issue as I understand it is largely companies that have five thousand computers with version X and they need to buy a dozen more computers. They don't want to have five thousand computers with Version X and a dozen with version X+1. They want everything to be the same, and they don't necessarily want to upgrade what they've already got to achieve that. APL (talk) 19:29, 7 April 2008 (UTC)[reply]

This sort of user-restrictive policy is difficult to enforce (what if they use Epiphany, or Konqueror, or Lynx, or W3, or...?) and is generally taken to be against the spirit of FLOSS anyway; if there were an /etc/cookies file, it (probably) wouldn't override the user's own cookies, and if it did by default there would be a trivial way (like firefox --no-etc or so) to ignore them. That said, there's nothing stopping you from writing a script that periodically overwrites /home/*/.mozilla/firefox/*/cookies.txt with all the same cookies except those for google.com. — although woe be unto you if you corrupt your users' cookie files! — or modifying Firefox itself to obey your rules — but remember the multiple-browsers thing; even bash can be used as an extremely simple "web browser"! --Tardis (talk) 13:30, 7 April 2008 (UTC)[reply]

Laptop idles at 140˚ F, normal/problem?

When I purchased my Macbook it was fine, really.

Between the F, G, and V keys, it is cool to the touch while the rest of the computer is blazing hot, I can't even hold my finger on the hinge where the monitor connects to the body.

Realtek drivers not detecting plugged in speakers/headphones

My computer recently stopped detecting when I plug anything into it to try and get sound output. As a result, the sound is no longer working.

I guess I'm just not getting your point. Let me "replay" to you what I think you've said: Your computer has a jack which outputs sound to external speakers or a headphone. Lately, you haven't been able to get any sound out of that jack, even though you've tried multiple sets of headphones and these headphones are known to work elsewhere (in a Walkman or an iPod or something). For some reason, you've concluded that the problem is the software in the computer.

Did I state that all correctly?

The part I can't get past is why you don't think the problem is the hardware of the headphone jack. After all, frequently-used connectors break much more frequently than just about anything else in a computer except maybe for the fans.

Excel formatting

I have a Microsoft Excel document with 33 sheets, and I want to adjust the cell sizes on them, exactly the same for each (I'm making up 33 schedules). Is there a way to "copy and paste" the format so I don't have to manually shrink 15 columns on 33 sheets? (That is a lot of columns to do!)

Try selecting the whole sheet (click on the empty button diagonally up and left from A1 cell) and then copying/pasting. Admiral Norton (talk) 15:27, 7 April 2008 (UTC)[reply]
(edit conflict) The format painter works, but don't forget that you will need to apply it to the column or row as a whole, not to the individual cells in the column. It's also possible to export the sheet as a .XML file and then use a competent text-editor (as compared to Excel) to make the column width/row height changes that you have in mind.

sockets is a disambiguation page. I hope you looked at Internet socket and maybe Berkeley sockets. "A socket is one of the endpoints of a network connection" is as simple as it's going to get. (Not entirely true because there are forms of network communication not based on "connections", and sockets are used for those too.) To add a little more detail, from the programmer's point of view, a socket is an object that can perform network-related operations such as: initiating a connection to another host; waiting for another host to initiate a connection; sending and receiving data on the established connection. --tcsetattr (talk / contribs) 19:21, 7 April 2008 (UTC)[reply]

RFC 1192, titled "Commercialization of the Internet Summary Report", written in 1990 (during the transition period), says:
  Under the draft acceptable use policy in effect from 1988 to mid-
  1990, use of the NSFNET backbone had to support the purpose of
  "scientific research and other scholarly activities."  The interim
  policy promulgated in June 1990 is the same, except that the purpose
  of the NSFNET is now "to support research and education in and among
  academic institutions in the U.S. by access to unique resources and
  the opportunity for collaborative work."
The keywords to finding more information are "NSFNET Acceptable Use Policy. Google finds many references: http://www.google.com/search?q=nsfnet+acceptable+use+policy
One of them appears to be a copy of the 1988 policy: http://www.cni.org/docs/infopols/NSF.html where "no commerical use" is found in rule number 7.

I don't follow your problem, either. I would love it if you could migrate to Mozilla Firefox, but unless we know what caused the problem, we will not know if Mozilla Firefox will solve it. Automatic refresh is a feature which, I am sure, IE7 (I assumed 7 since you are on Vista, your story may be different if you have addons installed) does not have this feature.

PowerPoint VBA question

I would like to make it so that in a given (pre-existing) PowerPoint presentation, every time I hit "next slide", the screen goes totally black for a period of X milliseconds, and then goes to the next slide as usual.

Any idea where to start in terms of the VBA? I've been trying to figure out, just to begin with, how to "catch" the next slide event in VBA, but I'm struggling. The sample code I've found doesn't seem to work for PowerPoint 2004 for Mac. This should be possible, yes? I'm very handy in general with VBA, but I've never used it in PowerPoint before so this is an object model I'm not familiar with. --Captain Ref Desk (talk) 00:42, 8 April 2008 (UTC)[reply]

Maybe not much help to you, but Powerpoint 2007 (Windows) already has exactly the type of slide transition you desire, built in - either fade to black then fade in next slide, or switch to black then switch to next slide - at a speed that is "slow", "medium" or "fast"; sorry no milliseconds, but fast was like an eye blink when I tried it. I wonder if the same transitions are in Powerpoint 2008 for Mac? Astronaut (talk) 01:02, 8 April 2008 (UTC)[reply]
Hmm, that's an idea I hadn't thought of, though I doubt the built-in transitions will accommodate. I don't want it to fade, I want it to go like this: slide 1 -> black (.5 seconds) -> slide 2. Click-clack. Herky jerky. On purpose and all. But I'll look into making custom transitions, that might be my best shot. --Captain Ref Desk (talk) 01:26, 8 April 2008 (UTC)[reply]
Now that I play with it, the one that comes closest to approximating what I want is called "Cut through black." I just wish I could extend the black period a bit. --Captain Ref Desk (talk) 01:49, 8 April 2008 (UTC)[reply]

I had thought of that, but I'd like it to be something portable and easy to use. Keeping track of extra slides would be a real pain. --Captain Ref Desk (talk) 17:42, 8 April 2008 (UTC)[reply]
Using cut through black (and fade through black) with the transition speed set to slow, gives about 0.5 secs of black. Astronaut (talk) 12:09, 8 April 2008 (UTC)[reply]
I wasn't able to change the transition speed for "cut to black" on mine (and again, fade to black won't work for this), it goes pretty fast. --Captain Ref Desk (talk) 17:42, 8 April 2008 (UTC)[reply]

A piece of advice: try putting an empty slide with a black background in-between and set the animation on that black slide to automatically advance to the next slide in whatever time you want. Then, put any transitions you want. Nice, easy and no VBA. Although it might not look very nice while editing in Powerpoint, it works just fine during a slide show.

Hi, i've been creating some off-line swf files for one of my colleagues to demonstrate our goods on her computer(Mac) to potential clients .

When i import a video to the timeline using Actionscript 3 and compile, it performs less than desirably - skipped frames; slow playback; sudden, overly fast playback, etc. I convert(rewrite) the file (actionscript and all) to Actionscript 2 and it runs a lot smoother .

I'd like to keep with As3 if possible of course, but this is effecting how i construct my files - i'm wary of using As3 for mulitple or large videos now .

Any ideas of why this is? I've got the latest ver of Flash player installed, etc ... on a pretty quick Mac . I'm placing the video directly on the timeline .

Any advice / work-arounds / better ways of doing things? Boomshanka (talk) 04:43, 8 April 2008 (UTC)[reply]

Random name generation algorithms

I developed a simple random name generator in Ruby - simply a method that returned a string containing a randomly generated "fantasy" name. The algorithm worked thusly:

a) Create an empty string
b) Add a consonant
c) Add a vowel
d) Continue steps b) and c) for a randomly generated number of times (I limit the number between 3 and 10).

This basic method uses the simple trick that alternating consonant / vowel etc. will generate a nonsensical but "realistic" fantastical name. However the results are extremely simplistic and have no real "depth" or particular style:


Huw

Nilog

Reticuf

Bili

Heruman

Folupiw


Some of these, such as "Huw" and "Heruman" are acceptable whereas "Folupiw" and "Reticuf" look too random. I'm looking to develop this algorithm to something better, but I'm unsure where to start. I read a great article online somewhere a long time ago about markov chain algorithms that take a list of hand-written names and generate results based on the statistical likelihood of a letter appearing after a certain previous one. Any ideas? 81.187.252.174 (talk) —Preceding comment was added at 07:15, 8 April 2008 (UTC)[reply]

Maybe have a list of pre-written name endings that are used 25% of the time or something.. a lot of names in Tolkien end in "-in" (Turin, Hurin, Fingolfin..) for example. Also don't just pick a random consonant.. have a list of which consonants are appropriate after which vowels, and which vowels are appropriate after which consonants. You wouldn't want an a after a q- you only want a u. And a w after an i is also unacceptable. Tailor all of this to the style you're going for and just keep adding more conditions until you're satisfied :D\=< (talk) 07:22, 8 April 2008 (UTC)[reply]
Maybe consonant cluster and phonotactics may help. --Kjoonlee 07:36, 8 April 2008 (UTC)[reply]
Along with the consonant cluster suggestion (like "sh", "th", and "ch"), also use vowel clusters, like "oo", "au", "ai", etc. StuRat (talk) 11:47, 8 April 2008 (UTC)[reply]
That reminds me of some other articles, like diphthong and digraph (orthography). --Kjoonlee 11:52, 8 April 2008 (UTC)[reply]
Thanks for the replies! Letter grouping rules sounds like the next step. Anyone know much about implementing Markov chain algorithms to generate names? The advantage of this is you can literally define the "style" of the name from providing a list. For instance, if I "plug" in a text file full of names from China, I'll get Chinese sounding names - if I plug in a text file full of names from Sweden, I'll get Swedish sounding names. The main problem is I'm not sure how to approach it -- is there any literature available (particularily source code?) 81.187.252.174 (talk) —Preceding comment was added at 12:32, 8 April 2008 (UTC)[reply]

Firefox Update

I'm not sure if this is just me or what, but since I got the new update for Firefox yesterday, I have lost my 'back' and 'forward' buttons. Is this a mistake on the update? If not, is there anyway I can get them to appear again?

Also, I use an addon which gives me a 'speed dial', like in Opera, and everytime Firefox updates, this gets disabled. Is there any way I can re-enable addons which have been disabled?

"Lossless" DVD Video ripping/archiving

(DVD Video encoded in lossy MPEG-2)

Is there any sort of "lossless" DVD ripping/archiving? The output file size should be the same as the input. There is no need for compression.

Think of it as lossless archiving of a JPEG file or a MP3 file: All you need is to copy the input file. The decoder can read those formats. If you convert it to a PNG of FLAC the output file size will be much bigger. So you need to use the same lossy encoding.

The is no need that any media player could play it, one media player is enough - it could be a program that specially created to play this kind of files.

Can ISO do that? Are there media player to play ISO on-the-fly? —Preceding unsigned comment added by 89.0.6.8 (talk) 09:40, 8 April 2008 (UTC)[reply]

Keyboard buffering

You know the behaviour exhibited by a lot of traditional computer programs (say bash for example) where you can continue to type as bash is doing something and it (or something, whatever it is) will store up your key presses until it's ready for them? eg you can type ls<enter>ls<enter> as quickly as you like and you'll end up with it running ls twice. Now consider a form on a web browser - you fill some things in and press enter and get a new form. Now normally there'd be no "keyboard buffering" or at least the keyboard buffering wouldn't do what you want - ie wait for the next form. What solutions / workarounds exist for this? --194.223.156.1 (talk) 15:31, 8 April 2008 (UTC)[reply]

That is a behavior of the web browser, not the web page. You can fake it by using JavaScript to buffer key presses and AJAX to change the content (so you don't break the continuity of the JavaScript). AJAX will use the buffer to fill in the new form when it finishes loading. -- kainaw 15:40, 8 April 2008 (UTC)[reply]

Hooking up a laptop drive

A friend of mine says their Macbook hard drive has died and wants me to take a quick look at it (their tech support wants to charge them $700 for the honor of giving it a shot, which I find a bit excessive). Unfortunately the tech support has already taken it out of the laptop housing and installed a new harddrive in it. I'm pretty sure it is a SATA drive of some sort.

What's the best approach? I've excavated data from bad/buggy drives before but usually it has involved chaining laptops up using Firewire or trying to hook the problematic drive as a slave drive. I'm not really interested in buying an enclosure for just this purpose, especially if the possibility of it working at all is low. I was thinking about hooking it up as a slave drive to my old PC but I haven't the slightest idea whether the drive connections will be compatible. (Obviously, once I have the drive, it will be more straightforward.)

Anyway -- I guess I don't have a specific question, but am phrasing this more as a general query. Thoughts? --Captain Ref Desk (talk) 17:37, 8 April 2008 (UTC)[reply]

Right, I know that (and tried to indicate that above, guess I wasn't clear), but the hard drive needs to be hooked into a preexisting laptop for that to work. In this case, I just have the drive; I don't have a laptop to hook it into. --Captain Ref Desk (talk) 00:27, 9 April 2008 (UTC)[reply]
Oh, I see -- sorry. Buy a cheap "external hard drive mounting box" that will support the SATA drive on the inside and whatever connectivity (FireWire, USB, ESATA) you have on the outside. Such a box will come in handy time and time again over the years. (And remember that converters are available between SATA and PATA in case you can't find a SATA mounting box. Converters are also available between full-sized PATA and the mini-PATA used on 2-1/2" drives.)

Sharing an IP

When we share an IP, how do other servers know whom to send a request. I mean, there must something else there to mark packages passing through the network, right? WikiWiking (talk) 18:11, 8 April 2008 (UTC)[reply]

You may be sharing an external IP, but you are not sharing an internal IP - which is also in the packet as it goes back and forth. So, once your router gets the packet sent to the external IP, it unpacks the packet based on the internet IP and knows where it is supposed to go. When it gets an internal packet, it wraps it in the external IP and sends it off. -- kainaw 18:42, 8 April 2008 (UTC)[reply]
The IP packets are sorted-out based on their serial numbers (which normally vary widely from one user of the IP to another user). See NAT.
Atlant (talk) 19:01, 8 April 2008 (UTC)[reply]
What Kainaw said is basically correct, but I wouldn't put it that way. I'd say the "internal" IP is only known by computers in the local network, so it wouldn't go back and forth the Internet, only the local net. --Kjoonlee 19:08, 8 April 2008 (UTC)[reply]
Let's say you're at an office where everybody shares a telephone number. Somewhat weirdly, everybody can call each other, but only the operator can call and receive phone calls. If you want to talk to someone on the outside, you call the operator, who calls the other person for you. When someone on the outside wants to calls you back, that person has to go through the operator and ask, "I was talking with some person about this-and-this; do you know who it is?" So the operator needs to remember what the call was about and put the call through. This is roughly how NAT works. Internal IP addresses correspond roughly to how internal phone numbers work. --Kjoonlee 19:20, 8 April 2008 (UTC)[reply]
Ok, lets forget the analogies and vague answers and just tell the guy what's actually happening: a packet travelling on the internet contains these two pieces of information in order to know where it's going: an IP address and a port number. The port number just essentially informs the receiving computer what internet socket that should handle the data. That way, you can have 20 connections alive at any one moment, and they don't get confused because they all have different port numbers. If you get a packet to port 80, that goes to your HTTP server, a packet going to port 25 is an email packet, and so forth. When you connect to a foreign server, your computer creates a new socket on a random port with a high number, like 32431, so that when the server responds it knows what port it should sent it to.
This is also how NAT-routers knows what packet to send to whom. If it sees a packet leaving computer with an internal IP (that is, your local IP-address, not your public IP-address) of 192.168.1.105 which specifies a return port of 32431, it knows that when the router receives a pack with a destination port of 32431, it knows that it should go to 192.168.1.105. Let's illustrate this with an example conversation:
  • A computer on a local network with local IP 192.168.1.105 wants to send a packet to 72.14.207.99 port 80 (also known as google.com). It specifies return port 45673.
  • The NAT router sees that 192.168.1.105 is sending a packet to 72.14.207.99, and it specifies return port 45673. It remembers that.
  • Google recieves the packet and sends one in return, with the router IP as destination and destination port 45673.
  • The NAT router recieves googles packet, and now it has to figure out what computer on the local network should receive it. Oh, look, 192.168.1.105 just sent a packet to google with a return port of 45673! It must be that computer that wants it!
  • 192.168.1.105 receives the answer to the packet it sent.
Get it? So you're basically right, there is something else that marks the packet with additional information, the port number. It wasn't intended really to be used that way, but it works fine. --Oskar 20:46, 8 April 2008 (UTC)[reply]

using my cache

It there a way I can save my cache into a working copy of ofline web files? —Preceding unsigned comment added by 212.159.16.175 (talk) 18:59, 8 April 2008 (UTC)[reply]

As long as your browser is actually storing the cache contents onto the disk, they're stored as ordinary files. (Not all browsers use a disk cache; the browser I'm using right now is configured to just use a very large memory cache.) It may be tough to figure out what's what based on the weird filenames, but it's all there and you can copy it out just like any other files.
Atlant (talk) 19:03, 8 April 2008 (UTC)[reply]
So, in theory I could copy the cache from loads of different browsers into one directory and then later past them into my own browsers cache folder and have a working ofline internet?
Each browser usuaully has some sort of "cache control file" as well that contains metadata about what's in that browser's cache. Because of this, you can't just arbitrarily copy-in the varous HTML bits, GIF bits, and the like and expect to be able to browse that collection. The files are useful individually, though.
Atlant (talk) 19:13, 8 April 2008 (UTC)[reply]
Google Gears promises to give some of that capability in the future. A developers' version is available for you to work with. Please read our article on it. You might also want to look at ScrapBook as a working solution (you can set ScrapBook to save everything that you browse automatically). Another related extension is Zotero which is "partly a piece of reference management software". I hope that helps. Kushal 23:33, 8 April 2008 (UTC)[reply]

Sorry for the bad news, but I don't think you are going to have much luck with this. I hope I'm wrong, but here is why I think so. I got "Via Voice" for free with some other software I purchased. I'm thinking it was only $20 or so. Now, this was in 1999, but I think the software works the same nowadays. How it worked was, you would say paragraphs of text as the words were highlighted on the screen. Same idea as karaoke. Based on how the USER pronounced words, it learned THAT voice. There is just too many dialects, accents and slang out there for it to know what every voice is pronouncing. If you think about it, you know that our brain does not make out every word said, but it "fills in" based on the context, body language, inflection...
Here's the 2005 version of that software: http://www.nuance.com/viavoice/
Why I also think the technology is not where it needs to be yet is based on the job my cell phone does. It does fine with "digit dial". It knows it's only listening for 0 to 9. But when it comes to "name dial" I have to mispronounce some of my friends names to get it to dial them - and that is with a very limited menu of possibilities.
If you do find something, please post it here. I'd love to have it myself.--Wonderley (talk) 06:53, 9 April 2008 (UTC)[reply]

Games crashing out

I run a Maxdata dualcore 3.4g computer with 1g RAM and an ATI 1600XT card. Recently I felt like a bit of Quake 4 so I installed it up and blasted merrily away for an hour or so. Then the computer started crashing in a way I had not encountered before. The graphics stutter briefly, then the game crashes out to the desktop, then, with no warning text or choices, the PC calmly shuts itself down, going through the usual blue goodbye screen. When I turn it back on, it does so without fuss.

I wondered if it was a problem with the Quake install, so I tried Doom3, with the same results. My PC runs fine otherwise, and copes happily with fairly demanding apps like Photoshop. I wondered if the graphics card was overheating, but usually if it gets hot the control software sends me a polite message on screen. I tried playing with the case open, and updated the drivers for the card but got the same results. Any ideas? Cheers. FreeMorpheme (talk) 07:20, 9 April 2008 (UTC)[reply]

Ubuntu Root

I'm hoping someone can save my sanity... I installed Ubuntu 7.04, and subsequently upgraded it to 7.10. At no point did the installation ask me to create a ROOT password. Now, however, I have come to install version 8.04, and there are an untold number of problems, all down to the fact that the software wants to update 2 files (gcc-3.3.doc and gcc-3.4.doc), neither of which it can access because they are 'owned' by Root. Does anybody know if there is a default Root password? I have hunted high and low on the web without success, including the usual suspects (ubuntu's homepage, various bulletin boards, and so on...) This problem has been going on for days now, and is preventing me from using many of the programs I would normally use day-to-day... Samilong (talk) 10:11, 9 April 2008 (UTC)[reply]

There is no default root password on ubuntu; you're supposed to use sudo for all your root purposes. If you really, really, really, really want a root terminal, you can type in "sudo -i" and enter your password (your user password, assuming your user is the admin on the computer). There, now you're root. If you want to start a root instance of the file-browser, type in "sudo nautilus" at the terminal. If you want to change the owner of those two files, type "sudo chown [your user name] [the file name]" in the terminal. --Oskar 10:35, 9 April 2008 (UTC)[reply]
BTW, if you need a little more basic help, like how to work a terminal or to change file permissions or something like that, we'll be glad to help. Cheers. --Oskar 10:36, 9 April 2008 (UTC)[reply]
Oh, and another thing. If you do stuff using the root account, be careful. Changing stubborn file-ownerships of individual files is usually no big deal, but don't go crazy and start using it when you don't need to. Sudo has weapons of mass operating system destruction capabilities. You really only rarely need to change stuff outside of your home-folder manually. If you want to install a program, use "apt-get" or synaptic (or the neat little "Add/Remove Software" GUI that's in the main applications menu). --Oskar 10:55, 9 April 2008 (UTC)[reply]
Here comes the light with which to cast back these shadowy sudo demons!! Apparently I'm the only one here who hates retarded sudo for a desktop distro and will give this fellow what he's asking for. Dum da da dum:
sudo passwd
This runs "passwd" as root so it sets the root password to whatever you give at the prompt. Also upgrading ubuntu is a bad idea. :D\=< (talk) 11:03, 9 April 2008 (UTC)[reply]
Honestly, I don't know what's up with you people who wants to log in as root. I mean, it's sooooo much nicer to just use sudo! No need to constantly log in and out with root, and as I said, if you really, really, really, really wants a root terminal, "sudo -i" is just seven keystrokes away. All hail the glorious Superuser-Do! --Oskar 11:30, 9 April 2008 (UTC)[reply]
no need to constantly type sudo... :) anyway I have sudo configured to only stay authenticated for that single command and to require the actual root password, not the user's password.. so it's pretty much identical to su except for the convenience of auto de-elevating from root. :D\=< (talk) 12:16, 9 April 2008 (UTC)[reply]


using a digital photo frame as an ebook reader?

Would it be possible to use a digital photo frame as an ebook reader? They take memory cards, so if I put jpeg (or whatever) scans of the text I want to read on one, can't I use a digital photo frame to flip through them and read them? Maybe since their resolution is so low 800x600 maybe, I should create several photos of each page. Still, I have very little money for an ebook reader, so, would this work? —Preceding unsigned comment added by 79.122.13.205 (talk) 13:46, 9 April 2008 (UTC)[reply]

As you said, you'd need several pics of each page, which means you could store fewer total pages. This, combined with the lower memory on most digital photo frames means you likely can't store even an entire book on one. But, if you want to load one chapter each day I suppose that could work. Also note that books you just scan won't look as good as those which are first scanned, have OCR applied, and then have "perfect" letters recreated. StuRat (talk) 15:15, 9 April 2008 (UTC)[reply]

well I thought since it had removable memory I could store in toto as much as I wanted.... Anyway I'm a very very poor student, what do you think the cheapest photo frame is that can support memory cards? —Preceding unsigned comment added by 79.122.13.205 (talk) 17:21, 9 April 2008 (UTC)[reply]

Photo frames do not have scrolling (up/down/left/right) capability. So, you will be viewing the image as is. You can't zoom in and scroll around. Also, there is no easy way to flip forwards/backwards between photos - especially the ability to jump to whatever page you like. As you can see, the big difference is functionality of the hardware - not just the resolution of the screen. -- kainaw 18:18, 9 April 2008 (UTC)[reply]

Delay after locking computer

After locking my computer (Windows+L), there's sometimes a looong wait (up to three minutes) before the "enter password" dialog appears. What could be causing this? System: Windows XP Pro SP2. --grawity talk / PGP 14:55, 9 April 2008 (UTC)[reply]

I suspect the problem might be that you are using Windows...;-) Seriously, though, it sounds like a resources issue; have you downloaded all the latest updates and bug-fixes from Microsoft? If not, that would be my first port of call - or install SP3... Samilong (talk) 15:39, 9 April 2008 (UTC)[reply]

Why is USB important?

why have usb ports become increasingly important. can someone tell me the answer. (E-Mail removed) —Preceding unsigned comment added by 81.103.97.82 (talk) 15:55, 9 April 2008 (UTC)[reply]

Do you know what USB is? The article we have is pretty good and should tell you what you need to know. Friday (talk) 16:38, 9 April 2008 (UTC)[reply]
Previous PC interfaces like RS-232 and SCSI did not support humping dogs or compact missile launchers. As office workers became more dependent on these tools, USB evolved to also support things like keyboards, mice, and mass storage devices. This progress made the earlier types of ports obsolete (they didn't even support pregnancy tests!), so now we mostly have USB. -- Coneslayer (talk) 17:39, 9 April 2008 (UTC)[reply]
Yeah, USB flash drives made Zip drives and Jazz drives (both of which were thought to be the likely successor to the floppy drive) obsolete. They're faster, cheaper, and have greater storage capacity. Useight (talk) 23:10, 9 April 2008 (UTC)[reply]

Correct term

What is the correct term, if I were to say "Wikipedia is on the..." internet, world wide web, web, net, interweb? —Preceding unsigned comment added by 212.159.16.175 (talk) 19:12, 9 April 2008 (UTC)[reply]

The way I understand is Wikipedia is on the World wide web. The world wide web is a part of the Internet (abbreviated as net). Interweb is the creation of a confused mind. (Just don't tell Butters (South Park) that he is confused :D.) If I am correct, you can always correctly say, Wikipedia is on the Internet, and not worry about the protocols the computers use to talk to each other. Kushal 19:37, 9 April 2008 (UTC)[reply]
Any of them except the last one is ok (only use the last one if you want to sound like a douche). --Oskar 19:40, 9 April 2008 (UTC)[reply]
I believe "Internet" is supposed to refer to the hardware, actual cables, hubs, routers, etc, while "World Wide Web" refers to the software (browsers, HTML pages, etc.). However, people use them interchangeably. Useight (talk) 23:07, 9 April 2008 (UTC)[reply]

Hosting

What companies are like 'the hosting company of everyone' or like a VW of hosting?WikiWiking (talk) 19:52, 9 April 2008 (UTC)[reply]

I don't quite understand the question. In what aspect should the "hosting company" be similar to Volkswagen? I agree that VW makes fine cars but I don't quite get what you imply by "like a VW". I am curious to learn more about it. Care to explain? Kushal 22:03, 9 April 2008 (UTC)[reply]
As far as I can tell, the questioner is asking if there are any "we do it all for you" hosting companies. Yes. In fact, I own one. We do everything (including some in-office computer support). However, it is very expensive. So, I would call it something like the Ferrari of hosting, not the VW. If, instead, the questioner is asking if there are any hosting services that are so cheap that anyone can have one, but it only provides the basic functionality - then yes, there are those too. I saw one for $5/year once. -- kainaw 22:51, 9 April 2008 (UTC)[reply]

How to let a third-party developer modify a website safely?

Hi all, I have a website running a off-the-shelf CMS (GeekLog). I have some basic grasp of PHP and MySQL, enough to have made a couple of changes, but I'm not so hot. I have plans for some upgrades, and have been considering renting a coder for not too much (therefore I'm not going to be able to afford the cream of the crop with hundreds of references and testimonials). What is the general way to allow an unknown coder to modify my website?

I'm not so worried about there being anything to steal (although if he changes the passwords on me and sells the domain to someone else I'd be annoyed...), it's more than he may have to be working on the underlying code base, and so wouldn;t want the thing to come crashing down.

Do people usually give the admin passwords to the developers? Can he somehow download the whole site, make the changes he needs to, and have me upload those changes? What's the best way of dealing with this?

Thanks!
