Remote camera

Here is what I would like to set up:

• 1) A camcorder filming constantly in one room
• 2) The picture being displayed on my TV in another room (via an RF or SCART input)
• 3) The signal being somehow encrypted

Can anybody tell me what technology I could use to implement this, please? WiFiSouls (talk) 00:56, 20 December 2008 (UTC)

To encrypt the signal, it will have to be digital. One of methods would be using computers at both ends and transfer video through computer network. (there probably exists dedicated solutions as well). At camcorder end, there will be necesary some means of getting video in computer (and probably transcoding)(although 100Mbit ethernet should be able to handle DV format video (wifi will not, so it will require transcoding)). Computer network could be encrypted by using VPN. At other end, omputer will have rto run some sort of media player and display video on TV. I am not aware of any video cards having direct RF or SCART outputs, but there are composite to SCART adapters, and dedicated (not built in) video cards with composite and s-video outputs are common. -Yyy (talk) 06:00, 20 December 2008 (UTC)

Not necessarily. Most cable headends were using systems that rearranged the video lines or inverted sync or something to like to 'scramble' pay-TV. You might be able to purchase this equipment used, now that everything else is going to digital. However, I don't think I can really recommend it. Ask yourself this: Does it need to be encrypted, or just difficult to intercept? I suspect the latter, in which case, have you considered just using a really long cable? Using something called a 'balun', you can even run your video over twisted pair cables. --Mdwyer (talk) 16:59, 21 December 2008 (UTC)

What we know is this: Camcorders' don't encrypt. So there has to be something connected to the camcorder to make it do that - and that something has to be a computer. Camcorders are a pain to connect to a computer - that says you should probably use a webcam instead of a camcorder (Webcams are amazingly cheap - so tying it up 24/7 doing this job is a better bet anyway). So the computer can grab the video and encrypt it. You don't say that there can't be a cable between the two rooms...but it's hard to imagine that you'd bother encrypting a signal that just goes between two rooms in one house - so perhaps you're talking about a room somewhere a long way off? In that case, pretty much the only way to get the data there is over the Internet. That means you need another computer at the TV set end (you need that anyway because you've got to decrypt the video and that's a job for a computer)...with a video output that's TV-compatible.

Unless you have REALLY strong reasons for wanting to do this EXACT thing - I think you should consider using the screen of the second computer to watch the video on instead of a TV set - and I severely doubt you really need encryption. That being the case, a simple Internet-capable webcam and a regular computer will do the job just fine. SteveBaker (talk) 00:05, 22 December 2008 (UTC)

Oh no

I tried entering the "format" command on my computer just to see what would happen, and I got a message saying "Paremeter line missing" or something of the sort. Does this mean the "format" command didn't work? Or does it mean it will work later on? Please. I don't want to damage my computer. 124.180.116.201 (talk) 05:08, 20 December 2008 (UTC)

You probably did not specify what to format, so command did nothing (and will not later on). To format a drive, use "format drive:", where drive is a drive letter for drive to be formatted. It will probably ask if ypu really want to format, when trying to format hard drive. -Yyy (talk) 05:48, 20 December 2008 (UTC)

If you don't know how the more dangerous commands work, please, please, spare yourself a lot of time and grief, and don't play with them. You can easily delete your entire hard disk with the Format command. Just don't mess with it unless you have a good idea of what you are trying to do with it. --98.217.8.46 (talk) 15:51, 20 December 2008 (UTC)

Yeah - that was INCREDIBLY dangerous. The FORMAT command's job is to erase everything on your hard drive...irrevocably...no "undelete". Rule #1 about "unknown" commands is that you don't run them until you understand them! As it happens, you got lucky - you've gotta tell it which drive to reformat by passing the drive name as a parameter on the command line. That's what it was complaining about - and it's what saved you. SteveBaker (talk) 23:47, 21 December 2008 (UTC)

I remember someone trying to make me run a .bat script that would automatically format the hard drive. Would it have worked? —Preceding unsigned comment added by 82.43.88.87 (talk) 23:51, 21 December 2008 (UTC)

Well yes, it is perfectly possible to write the commands in a batch script and tell it to do it silently, but it would only work when Windows was not active. — neuro^(talk) 02:32, 22 December 2008 (UTC)

I recall some years ago I was working with a marketting guy (this was back in the era of DOS) - he called me on the phone saying that his PC had run out of disk space and I jokingly said "Well, you could always try 'RMDIR/S *.*' - ha ha!" (or something like that) - then went on to explain how he could look for junk files he didn't need anymore. Anyway, while I was talking, he interrupted me to say "That command seems to be taking an awful long time?"... SteveBaker (talk) 16:16, 23 December 2008 (UTC)

Texture file in games

You will probably need Adobe Photoshop Extended - that version has 3D support. Otherwise, you can use Autodesk's Maya. --wj32 ^t/c 09:52, 20 December 2008 (UTC)

Internet

220.225.242.194 (talk) 06:22, 20 December 2008 (UTC)harshagg How can I increase my internet speed without changing my plan's speed which server usually offer

No. Unfortunately, if you ask this question at various places on the internet, you'll be told a bunch of fairy tales that say you can, and you'll be subject to some downright cons. For lots of people, their service is already as fast as the network to their home will support - the internet company isn't clamping it, and if they could offer you a faster service with the same equipment they already would be. For the rest, who are clamped, that's done on a router through which all their traffic flows. It isn't possible to somehow trick that router into allowing more traffic that it has been told to. Now people will tell you nonsense about changing your MTU size, but for an ordinary user that's pointless (and may make things slower). You'll hear the "Windows QoS myth", which claims XP (etc.) reserve a portion of bandwidth, and that you can reclaim that by turning of QoS (it doesn't, and you can't). Then come the cons - people will sell you (or let you download for "free") programs that claim to optimise your connection - some will just automatically apply the above nonsense "hacks"; some will do stupider things that break how the internet protocol works (like the silly "ack flood" things, that acknowledge packets you haven't received yet, in the vain belief this will chivvy up websites etc. into sending stuff faster); and some will just be trojans that take over your machine. To get the fastest internet you can, make sure your machine is free of viruses and trojans, make sure your wireless connection is secure (so you're not inadvertently sharing the connection with your freeloading neighbours), and only run p2p filesharing and telephony programs when you actually want to use them (they're particularly profligate with bandwidth, even when you think they're not). 87.114.130.249 (talk) 11:00, 20 December 2008 (UTC)

Ooh. Well said. If you want to monitor your connection speed, use WireShark or something similar. Notice that I said monitor, not make faster. flaminglawyer^c 15:45, 20 December 2008 (UTC)

You can change your expectations though. If you have a slow connection you could set your connection so you rejected flash or even javascript for most sites except ones you approved, it would improve your security too. Dmcq (talk) 12:49, 21 December 2008 (UTC)

Sadly, I agree. The speed of the connection isn't limited by your computer - it's dependent on your ISP's setup. So without them doing something - you're screwed. The best advice I could give would be to use something like http://www.speedtest.net/ to measure your ACTUAL network speed (both up and down-stream) - and check that you're actually getting the bandwidth that your ISP promised you in your contract. If your performance is significantly less than they contracted to deliver to you (and that's a surprisingly common thing) - you could complain and they might even do something about it. But if they are delivering all of the performance they promised you - then your only option is to upgrade to a faster service or learn to live with what you've got. SteveBaker (talk) 23:28, 21 December 2008 (UTC)

Using a Sony Ericsson phone on Mac OSX

I use Mac OS X Leopard, and have a Sony Ericsson W595 phone. The software that comes with the phone is PC-only. How can I put songs onto the phone from my Mac?

Many thanks --Cash4alex (talk) 13:12, 20 December 2008 (UTC)

I've got the same phone, and I'm a windows (and linux) user. I never installed any of the software that came with the phone (among other reasons, because of this). You just need the usb-to-phone cable. When I plug it it, I get a menu on the phone display that allows me to chose between four different modes of operation. My menus are in Norwegian, so what follows is a translation which may not be exact:

 (Telephone icon)               Telephone mode
 (Usb icon)                     Media transfer
 (Icon with two drops of ink?)  Print out
 (Folder icon)                  Mass storage

Select the last one, with the folder icon. You'll be notified that you can't use your phone as a phone in this mode, and asked whether you want to continue. After responding "yes", the phone will appear as two new usb devices. Select the one that represents the memory card ("PHONE CARD"), not the one that represents built-in stuff ("PHONE"). Navigate to the folder called "music", and drag and drop your songs there. You can create sub-folders if you like, the phone will still find your songs, but the phone menus won't reflect your directory structure, but the ID3 tags of the songs. --NorwegianBlue ^talk 15:35, 20 December 2008 (UTC)

Does it have Bluetooth? If so, pair the phone with your computer and you can easily browse the contents using Bluetooth File Exchange in your Utilities folders. I had a 610 and s700 and I was able to easily drag and drop photos, voice memos, movies, ringtones and MP3 to and from the device over Bluetooth. I was also able to use iSync to sync Address Book contacts and Calendar events. --70.167.58.6 (talk) 03:25, 21 December 2008 (UTC)

Printing all possible k-subsets of a n-set

Hello. I want to write a program in C++ which given n and k, prints all possible combinations of k distinct numbers chosen out of 1,2...n. For example if n=4 and k=2 I want to print 12,13,14,23,24,34. (The order has to increasing as well, i.e. 32 is not permitted). I can't seem to get the looping done correctly to apply the brute force method for handling this program. Also, the brute force method would become infeasible to implement if n is big (something around 1000). What is the best approach to handle this problem? Thanks.--Shahab (talk) 14:16, 20 December 2008 (UTC)

It seems what you want to do is to generate permutations and then apply a trivial function to compose them (in your example, concatenation). If that's what you mean, then Permutation#Algorithms to generate permutations is for you. 87.114.130.249 (talk) 14:32, 20 December 2008 (UTC)

No I guess I don't want all permutations. I want a list of all possible k size subsets of a n size set. For example if n=10, k=2 then I want a list of ${\binom {10}{2}}=45$ numbers of the form 12,67,89 etc. That is all possible ways of selecting 2 numbers out of 1,2,...10. The should ideally be listed in increasing order, although that's not especially important. Thanks for the quick response though.--Shahab (talk) 14:41, 20 December 2008 (UTC)

You are going to want recursion. With for loops, you need a for loop for each iteration of k. If k=2, you need 2 for loops. If k=3, you need 3 for loops. It is rather difficult to write a program that magically increases or decreases the number of for loops it has. With recursion, you have 1 loop that calls itself as many times as needed. -- kainaw™ 14:57, 20 December 2008 (UTC)

Recursion is one approach, but a recursive loop 1000 steps deep is likely to break something. So, here's a non-recursive solution I wrote and tested in FORTRAN:

• Set this declaration as high as you like or use dynamic memory allocation:

    integer*2     ARY(29,100000)     ! Array of (digits,solutions).                                       
    integer*2     I,N,K,RECORD,DIGIT,VAL

• Initialization:

    RECORD = 1                       ! Current solution number.
    DIGIT  = 0                       ! Current digit.
    VAL    = 0                       ! Current value of digit.

• Make these user inputs to improve program:

    K = 2                            ! Number of digits.
    N = 4                            ! Number of values allowed for each digit.

• Body of program:

    IF (K .GT. N) GOTO 600           ! Abort if no solutions are possible.

200 DIGIT  = DIGIT + 1               ! Go to the next digit.

300 VAL = VAL + 1                    ! Go to, then store, the next value for the 
    ARY(DIGIT,RECORD) = VAL          !  current digit of the current solution.
    IF (DIGIT .LT. K) GOTO 200       ! Any more digits ?
400 IF (VAL   .LT. N) THEN           ! Any more values allowed for this digit ?
      RECORD = RECORD + 1            ! Go to the next solution.
      DO I = 1,DIGIT-1               ! Copy the old solution up to the previous digit.
        ARY(I,RECORD)= ARY(I,RECORD-1)
      ENDDO
      GOTO 300
    ENDIF

500 DIGIT  = DIGIT - 1               ! Go to the previous digit.
    IF (DIGIT .LT. 1) GOTO 600       ! If there's no previous digit, we're done.
    VAL = ARY(DIGIT,RECORD)          ! Get value of previous digit.
    IF (VAL+K-DIGIT .GE. N) GOTO 500 ! Digit's value already too high 
                                     !  to allow increasing values 
                                     !  to end of solution. 
    GOTO 400

• Program termination:

600 DO I =1,RECORD+1                 ! Add proper prints later.
      print *,ARY(1 ,I),ARY(2 ,I),ARY(3 ,I),ARY(4 ,I),ARY(5 ,I)
   +         ,ARY(6 ,I),ARY(7 ,I),ARY(8 ,I),ARY(9 ,I),ARY(10,I)
   +         ,ARY(11,I),ARY(12,I),ARY(13,I),ARY(14,I),ARY(15,I)
   +         ,ARY(16,I),ARY(17,I),ARY(18,I),ARY(19,I),ARY(20,I)
   +         ,ARY(21,I),ARY(22,I),ARY(23,I),ARY(24,I),ARY(25,I)
   +         ,ARY(26,I),ARY(27,I),ARY(28,I),ARY(29,I)
    ENDDO

Some things to add in C++ that FORTRAN does automatically:

1) Initialize the array to all zero values.

2) Include a space between each item printed.

3) Start each print on a new line.

Here's my output:

1 2 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0

2 3 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
2 4 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
3 4 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0

When I reformat your prints I get the following:

12000000000000000000000000004248480
13000000000000000000000000022895924199168
14000000000000000000000000002147299328
23000000000000000000000000022913480

00000000000000000000000000022901204198987

So, you're getting the correct output, but with some garbage values at what should be the end of each line, which probably will be fixed by initialization of all array values to 0 and fixing the prints (just printing the first 3 array elements instead of 29 would hide the ugly random numbers and make the output nicer for your particular test case). Also, isn't there something in C++ called "flushing the (print) buffer" ? Once you get it working, you can fancy up the prints a bit more, say by suppressing any prints of zeros. StuRat (talk) 15:44, 21 December 2008 (UTC)

If you still don't get the concept of how the program works, try going through it manually. That is, write all the variable names down on a piece of paper and record how the values change as you step through the program. For the array, you could maybe make a 3×7 chart and fill in the values as they are assigned. This technique can be tremendously helpful in understanding how programs work. Some debuggers can do this all automatically, but you would likely have to reduce the size of the array to 3×7 (I only made it bigger to show that the same techniques would work with much larger values for N and K).

portable disk corrupted

I was watching a video file from my portable disk when I accidentally disconnected the USB port, the media file stood still and after a few seconds the system warned me that the disk was corrupted. The data present inside it is of utmost importance and I can NEVER afford to lose it. So please tell me a way to repair my disk or recover that data. I even tried check disk on it but it wouldn't start. When I open that disk from "My Computer" I get the message "J: drive not accessible. Disk is corrupted and unreadable". I am not much knowledgeable about computers, thats why I am seeking help here in wiki. Thanks for the help. —Preceding unsigned comment added by 59.88.20.120 (talk) 16:43, 20 December 2008 (UTC)

Have you tried rebooting your computer and then trying again? It shouldn't have corrupted anything just to have it pulled out while it was watching a movie. (In the future, if you have something you CANNOT afford to lose, store it somewhere else as well as a USB drive. USB drives are very convenient but they are NOT necessarily reliable; when they fail, they often fail totally and without warning.) --98.217.8.46 (talk) 17:34, 20 December 2008 (UTC)

Typing "usb flash drive corrupted" into Google reveals lots of pages that might be helpful, as well as this extremely technical description of what the problem could be. It features the line "...there is a bug with Windows 2000 (that MS never bothered to fix) and can corrupt the drive when it is removed without proper eject." ...

Spam solutions critique template author

There's a templated message that's been in use for a long time – since the age of Usenet – that is often used to critique new proposals to fight spam.

It starts off with

Your post advocates a
  ( ) technical
  ( ) legislative
  ( ) market-based
  ( ) vigilante
approach to fighting spam. Your idea will not work.
Here is why it won't work....

and then runs through several check-all-that-apply explanations and principles. A full copy is available here, and probably everywhere else on the 'Net.

Anyway, I was wondering — does anyone know the identity of the original author? As well, this document has been widely reproduced for many years; was it ever explicitly released into the public domain (or under any free license) by the copyright holder? TenOfAllTrades(talk) 17:31, 20 December 2008 (UTC)

I don't think it was ever copyrighted... it's the Internet. For the same reason I can say it's unlikely you'll ever find who wrote it. --grawity 09:25, 21 December 2008 (UTC)

Every creative work is copyrighted unless explicitly released. This applies on the internet as elsewhere. Algebraist 09:38, 21 December 2008 (UTC)

Well, if that person that OP linked to can post the full text without getting sued, and the fact that you said it's been used since the invention of Usenet, I believe that you could use it without any fear of legal repercussions or anything like that. flaminglawyer^c 14:52, 21 December 2008 (UTC)

There is often a broad gap between 'doing something that won't get you sued' and 'doing the right thing'. In any case, I'm not looking for (bad) legal advice — I'm genuinely interested in who the author is. TenOfAllTrades(talk) 20:37, 21 December 2008 (UTC)

Correct. You cannot use "they did it too" as a defense in court. As for the author, it is highly unlikely that the author will be possible to find. There are likely many people claiming to be the author. I've had a very similar experience. I pulled a hoax a long time ago (because I thought was going to get a book published and the hoax was a cool tie-in). Since then, I've found many people claim to have been the ones who created the hoax - and they have evidence to prove it. -- kainaw™ 21:08, 21 December 2008 (UTC)

I also suspect that the document has evolved over time; I wouldn't be surprised if there have been tweaks over the years (additional rationales have been added, etc.) and that there have been many contributions. Still, is there anyone who is strong in Google-fu who knows of the earliest Usenet mention? TenOfAllTrades(talk) 21:57, 21 December 2008 (UTC)

By now there will be dozens to hundreds of authors who contributed to the current version. Those things definitely evolve. A few years ago I got a funny email about "Top 10 things likely to be overheard if you had a Klingon on your software development team" - it was OK - but I added a bunch more ideas to it and put it up on my web site (here: http://www.sjbaker.org/humor/klingon_programmer.html) - now do a Google search on a phrase found only in my version and you'll find over fourteen THOUSAND web sites are "mirroring" my additions to the original post. Of the few I looked at, several have improved on my version - culling out some of the weaker jokes and adding new ones. Now this 'meme' has spread and the "latest" versions probably have dozens or even hundreds of separate authors. Even if you could track down the original author, you wouldn't be able to get him/her to grant you legal rights to use the current version because there are an unknowable (and definitely uncontactable) number of amenders. Fortunately, people don't usually expect to enforce copyright on humor posts like that...but that doesn't change the law. SteveBaker (talk) 23:06, 21 December 2008 (UTC)

I think google's usenet searching is badly broken. I can't find any example of this post on usenet previous to 2004. I would bet good money that it's appeared on usenet at least as far back as the 1990s. APL (talk) 15:53, 22 December 2008 (UTC)

battery life: monitor or sound output?

What costs more battery power of an offline laptop: Writing in Word or listening to sound files via headphones (with the monitor switched off)? If it's the latter: How big is the difference--enough to be able to sometimes switch on the monitor and take notes in Word and still save battery life? (I'm trying to figure out how to maximize battery life while working out of reach of an outlet.) Thanks, Ibn Battuta (talk) 17:55, 20 December 2008 (UTC)

The two are probably much the same. For normal operations, power is consumed (more than usual) when the hard disk spins or the GPU fires up properly. Absent either of these, the difference between the two actions you describe is likely to be minimal. 87.114.130.249 (talk) 00:45, 21 December 2008 (UTC)

Utorrent check

I use utorrent to download files, but because I use public computers each time I start utorrent to resume downloading a file from the previous session, it goes through an extremely long checking sequence which can take upto half an hour for 20GB. I realize this checking is a vital function, but on my home pc it remembers what it has checked from session to session and just resumes straight away. So my question is, on public computers how can I make utorrent remember what it has check and just start downloading? Is there some registry files it needs to work from different pc to pc? Thanks. —Preceding unsigned comment added by 66.63.184.3 (talk) 21:15, 20 December 2008 (UTC)

Utorrent usually saves the resume information in C:\Documents and Settings\Owner\Application Data\utorrent, but you can make a portable utorrent. To do this put a clean version of utorrent.exe into it's own folder on your portable drive, then make a new text file (File -> New -> Text Document) and call it "settings.dat" making sure the file extension has been changed from .txt to the .dat extension. Now start utorrent and it will save all it's settings in that folder. You will have to go through the check sequence only once and it will remember it for the next session. However, this only works if the drive letter of your flash drive or portable hard disk remains the same on the computers you use. If you're using the same public computers but they just wipe the session data when you log off it should be ok, but if the drive letter changes it will cause errors.

Minefield → Shiretoko

Resolved

flaminglawyer^c 02:49, 21 December 2008 (UTC)

I use Minefield (the pre-pre-beta version Firefox) for my web browsing. It is updated nightly, so I get updates every day. One day, a couple weeks back, when it got updated, it changed names on me - it's now something calledShiretoko. It seems to be the same thing, but they have 2 seperate pages on the Mozilla website, so I assume there must be some subtle differences. Can someone tell me what the difference(s) is/are between these two programs? flaminglawyer^c 22:45, 20 December 2008 (UTC)

Minefield versions are all trunk builds - the latest versions of Firefox, irregardless of version. Shiretoko is the codename for Firefox 3.1; Shiretoko Alpha 2 has been released recently. --wj32 ^t/c 00:40, 21 December 2008 (UTC)

So Minefield is newer than Shiretoko, because Alphas are generally newer than Betas? flaminglawyer^c 14:50, 21 December 2008 (UTC)

Beta versions are newer than Alpha versions, and both are pre-release versions. Minefield builds are the latest version of Firefox (built nightly I think). On the Minefield page it says: "Warning: This is NOT A FINAL OR PRE-RELEASE VERSION." --wj32 ^t/c 05:16, 22 December 2008 (UTC)

Images in Safari, Firefox

I've noticed that in Safari and even in Firefox, often my computer decides to only try to load maybe 75% of the images on a page. Hitting reload usually gets the rest. This happens in particular with Google Images and Facebook, but often also happens with things like Google Maps (it'll load maybe half the tiles and then just give up, and just put a "loading" in place or sometimes a "can't load at this resolution" which is always incorrect here). What's the likely issue here? Any suggestions on fixing it? I have a MacBook, OS X 10.4.11, with the latest versions of both Safari and Firefox, with a usually pretty reliable internet connection. It's an irritating quirk. --98.217.8.46 (talk) 22:55, 20 December 2008 (UTC)

This is a common problem in Firefox, and one which there doesn't seem to be a fix for, but why Safari would also do it I don't know. Have you tried Opera to see if it also happens? The only thing I can think is you're getting a network timeout server closing the connection, especially if it's a very large image. There are some suggestions on a similar problem here which may help. SN0WKITT3N 19:44, 21 December 2008 (UTC)

Firefox doesn't do that under either Linux or Windows on dozens of machines I use regularly...if this is indeed Firefox-related and as common as that - then it must be associated with the Mac port of Firefox. Personally, I doubt it's Firefox's fault. If all Firefox/Mac installations did this on sites as common as GoogleMaps and Facebook, then the error reports would be all over the Firefox developer site at top importance levels - and they aren't. If you see it in Safari to then the problem certainly lies elsewhere. Something's screwy with your network setup - which is going to be tough to diagnose remotely. It certainly sounds like a network timeout though. SteveBaker (talk) 22:35, 21 December 2008 (UTC)

You're right, I was remembering Firefox used to do this all the time but since version 3 I've never had the problem. I found a few old bugzilla reports and questions about this but looks like if there was a problem they fixed it. SN0WKITT3N 22:54, 21 December 2008 (UTC)

Quantum GIS question

I'm trying to create a map for Virginia State Route 28. I've downloaded all the data I need, my map looks like the following: [1] My problem is with the colouring. How do I get, for example, the line representing 28 to become red, Interstate 66 to become blue, Virginia State Route 267 to become green, etc.? And how would I add the state border? Would I do all of this in Inkscape? Thanks in advance, a very confused Xenon54 (Frohe Feiertage!) 18:34, 21 December 2008 (UTC)

(it's good to know someone else uses Inkscape!) I assume you have it saved as an SVG. If you have the roads set to different objects, then you can change the colors easily by just selecting the object and clicking the color red on the color bar at the bottom. As for the state border - just use the bezier/straight line tool and draw it based on a real map. Or find an image of the state border (just a line), import it, and resize it to fit your map. flaminglawyer^c 20:01, 21 December 2008 (UTC)

FWIW: I use Inkscape a LOT!SteveBaker (talk) 22:21, 21 December 2008 (UTC)

That's what I thought I should do - except Quantum GIS' "Save As Image" function only saves as JPGs or PNGs. Any members of the maps task force around here? Xenon54 (Frohe Feiertage!) 20:07, 21 December 2008 (UTC)

Then this is something you'll have to do in something like Photoshop or GIMP (the latter is a free download). GIMP and Photoshop are 'raster' editors - Inkscape is for 'vector' images. You should tell your Quantum machine to save as PNG - NOT JPG. The artifacts caused by saving as JPEG will make your recoloring task VASTLY harder. SteveBaker (talk) 22:21, 21 December 2008 (UTC)

Thanks for the response. Xenon54 (Frohe Feiertage!) 22:33, 21 December 2008 (UTC)

Personally I disagree with Steve. You should look into how you can make the image an SVG. Many contributors are discouraging the use of raster images when the image can be best represented by a vector format (IMHO for good reason) and there's a good chance if you make a PNG it will be eventually replaced. In other words, rather then doing all this work for hothing, look at the way to do it properly even if it takes a little longer. From a quick search [2] it looks to me like Quantum GIS should be able to export to SVG. You may want to look for an export option instead of "Save as image" since image often means a raster image in the context of many programs. Nil Einne (talk) 13:29, 28 December 2008 (UTC)

Mass audio file data edit

I have many, many songs on my laptop. I now have 3 issues.

When I first uploaded them, I used the following file structure:

• Artist
  • Album
    • Disc no (for double albums)
      • Song name

Because I now also use an MP3 player, I would prefer the following file structure:

• Artist
  • Album
    • Disc no (for double albums)
      • Artist - Song name

I have already done this for my 'The Beatles' folder and my 'John Lennon' folder, but wondered if there is a quick and easy way to do it to all of them.

Secondly, I would like to edit the little pieces of info (what's it called - metadata or something?) like the song title, artist name, etc. Is there a quick way to do that?

Finally, some of my songs - seemingly at random - appear as 'Track 6' or something in Windows Media Player, despite the filename being different to that. Is there a way to fix that? Dendodge Talk^Contribs 21:46, 21 December 2008 (UTC)

ok, cause in itunes there should be an option to do what you want easily. For the "Track 6" problem you can use audacity to add a title to each track that will show in WMP. —Preceding unsigned comment added by 82.43.88.87 (talk) 22:36, 21 December 2008 (UTC)

Audacity isn't needed at all. On Windows (and probably other OS's) all you need to do it right click → Properties → Summary → Advanced. And you can just click to edit right there. flaminglawyer^c 22:46, 21 December 2008 (UTC)

I'm on Vista, and that doesn't seem to work. There's an 'ID tag' tab, which I guess is similar, but apparently I need a PowerPack to edit it. Plus it sounds like a long way - isn't there a way to automatically fill it in using the filename? Dendodge Talk^Contribs 23:13, 21 December 2008 (UTC)

(outdent) For the metadata editing problem, there is an "Advanced Tag Editor" (on XP) option that allowed me to edit every single tag associated with the file - not just artist and title but composer, genre, album, track no., even beats per minute. You can get there by right-clicking on a track in the WMP library and clicking Advanced Tag Editor. As for the filling-in of the data automatically, you will probably have to do that manually. You could always search download.com, etc. but it seems unlikely that such a program exists. Xenon54 (Frohe Feiertage!) 23:23, 21 December 2008 (UTC)

Try EasyTAG. It can fill in file metadata from filenames and rename files from their metadata. --wj32 ^t/c 01:44, 22 December 2008 (UTC)

foobar2000, whilst also being my absolute preferred audio player, has this feature as standard, and everything is done as simple tags (such as %album% %artist% %tracknumber%). — neuro^(talk) 02:28, 22 December 2008 (UTC)

Samsung is my favourite brand, I personally use an S730 which I find to be particularly good both value and quality wise (some of my pictures, for reference on how good it actually is, are here), and most medium quality or above cameras will not have webcam functionality. — neuro^(talk) 12:50, 22 December 2008 (UTC)

Both Logitech and Microsoft (and probably a bunch of others) have WebCam's that you can pick up for $25 new - or less on eBay. "Decent" is a relative term. Webcams (by definition) are intended to send video over the web - as such you don't need (and don't generally get) super high resolution. The $25 web cams produce reasonable images at poor resolution (640x480 maybe). Higher end digital cameras are not generally designed to 'stream' video. They capture it into memory locally. You might find a digital camera that can do it - but it's far from normal - and they'll generally cost you much more because they have to be built to consume very little battery power (a webcam can take as much as it needs), to produce super-high resolution (most digital cameras can do at least 3 megapixels - a webcam is typically only called upon to do half a megapixel), to store that in flash memory, to have a viewfinder and LCD viewer...a bunch of things that a basic webcam doesn't need and doesn't have. SteveBaker (talk) 15:53, 22 December 2008 (UTC)

Any suggestions on a specific webcam then? I'm willing to purchase over net or at Walmart/Target. Magog the Ogre (talk) 23:00, 22 December 2008 (UTC)

Actually when you talk about webcam, there's 2 different meanings, firstly something that will upload images regularly to a webpage every few seconds, and secondly something that can be used for video chat. Most digital cameras will support the former (my old Fuji FinePix could and I think most Canons can though I've not tried mine). However, streaming video for video chat is different, and they will not do that. --Maltelauridsbrigge (talk) 12:17, 23 December 2008 (UTC)

Hi! I'm a professional computer games programmer - I've been doing 3D graphics for close to 30 years. XNA is crap.

Use OpenGL (or, if you are absolutely, utterly certain that you never want to run on anything other than Windows or XBox - you might consider Direct3D). The 'ease' of XNA is a false lure - it's easy to do the easiest things - but when the going gets the slightest bit difficult, XNA becomes useless. If you start down the XNA path, you'll soon wish you hadn't - and then it'll be too late.

It seems Norton Anti Virus can get rid of it for you and I suspect that other Anti Virus software can remove it as well (perhaps your Anti Virus has ben compromised in some way). If you don't want to splash AUS$60 or more, you can try a manual removal. The word "TDSS" seems to be an important clue. Search your system for all files with "TDSS" in the filename, and search the registry for "TDSS". Delete the obvious candidates and move/rename the less obvious ones (remembering their old name/location). Reboot your PC. You might have to go round this process several times to be sure you have got all of it. One last thing: messing with the registry and system files carries a high risk of breaking Windows so bad that you need to reinstall everything. Make sure you back up anything you cannot afford to lose (ie. documents, photos, emails, etc.) before you start. Astronaut (talk) 13:06, 22 December 2008 (UTC)

Well no there aren't "plenty of viruses for *nix", but I do agree that Hoary's comment was a bit pointless. Anyway, go ahead and delete the virus' file. If you can. You see, while the virus is running, Windows locks the file so you can't delete it. You'll have to terminate the process first. If Windows Task Manager can't terminate the process, try IceSword or gmer or something else. You can also try booting from a GNU/Linux LiveCD with NTFS support or a Windows Live CD (see BartPE) and delete it from there.

The first thing you'll have to do is locate the virus' file. This can be done using Process Explorer (google it). If the virus is some sort of DLL, then it's going to be much harder. If it's a rootkit, use IceSword or gmer. --wj32 ^t/c 21:30, 22 December 2008 (UTC)

Actually, it's not that simple. This does have a rootkit component (thanks for the link, Astronaut). You'll first have to use IceSword's registry editor to delete HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\TDSServ, HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SafeBoot\Minimal\TDSServ.sys, HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SafeBoot\Minimal\TDSServ.sys and HKEY_LOCAL_MACHINE\SOFTWARE\TDSS. Then use IceSword to move any files that start with TDSS in C:\Windows\system32 to a backup directory. --wj32 ^t/c 21:42, 22 December 2008 (UTC)

I've heard that this virus can stop you from getting anti-virus programs. I don't know if this has happened to my computer, but what if it does? What can I do then? 60.230.124.64 (talk) 23:58, 22 December 2008 (UTC)

Please, stop worrying about what might happen if you "get an anti-virus" program. Search Google for IceSword and download it. Run it, and follow the instructions I just gave you. Sorry, but... your computer will not blow up if the rootkit you have prevents you from running an anti-virus program! --wj32 ^t/c 00:11, 23 December 2008 (UTC)

Yes, hunt down and kill any running processes and services that start with "TDSS". Process Explorer is good for that, and/or a rootkit killer such as IceSword if a rootkit is involved (though if you're running Vista you might have difficulty finding a rootkit killer that works). The big problem though is thinking you've got rid of it all, only to find it comes back afer a reboot. In my experience, it is possible to have multiple copies of the same virus or many different virus infections all hidden by the same rootkit. Getting them all is a long job.

The best guide is to be familar with what your PC loads at boot time and then check up on any changes. Anything that starts at boot time should be checked out (googling file names is one simple method - eg. googling "TDSServ.sys" gets 9,000+ hits mostly about malware). Astronaut (talk) 01:33, 23 December 2008 (UTC)

I used this program ComboFix a while back to get rid of some spyware/virus on a friend's computer after all other antispyware programs failed and I think the files it got rid of did start with TDSS... So maybe give it a shot. Cheers, --71.141.107.171 (talk) 04:59, 23 December 2008 (UTC)

I'm puzzled. I read above:

• Astronaut: it annoys me too when someone suggests changing your whole OS and migrating your stuff just to fix some minor Windows problem [...] messing with the registry and system files carries a high risk of breaking Windows so bad that you need to reinstall everything
• Wj32: there aren't "plenty of viruses for *nix", but I do agree that Hoary's comment was a bit pointless

Its point was that installing GNU/Linux is about as simple as the procedure suggested above, that it avoids the risk of the recurrence of something similar, and that it's free and doesn't require registration. Of course you'd copy your work files off the computer first; if this "backdoor.tidserv" malware prevents this, then you could do it after booting off some portable, CD-based alternative to the damaged Windows installation. -- Hoary (talk) 14:04, 23 December 2008 (UTC)

Amazingly (well, it amazes me anyway) some people actually WANT to run Windows. Advising them to switch to Linux - while fundamentally sound advice - isn't helping them solve their immediate problem - and is therefore likely to be rejected, typically with some degree of hostility. So it's probably best not to suggest it until they are in a better mood! But there can be no doubt whatever that in practical terms, Linux is safe from viruses. neuro says there are 'nix virii - which it technically true - but nobody ever suffers from them - so this is at best a misleading statement. I've been using Linux since almost day #1 (I downloaded it from Linus himself soon after it was first announced) - I don't take any precautions whatever against virus attacks - I visit dubious websites, I download stuff with impunity, open attachments from complete strangers, I don't have a virus checker or even a hardware firewall and I leave my computers (many of them) turned on 24/7 on open Internet connections and sometimes, even wireless routers without encryption. All sorts of things that would be rapidly fatal to a Windows user. But in 17 years of intensely reckless Linux/Internet use - I've not had a single virus, malware, rootkit or other inconvenience of any kind - and neither has any of my friends or colleagues who use Linux. So - you shouldn't make the switch because you have one specific problem - but in terms of general freedom from grief over the long term, it's a strong reason to change. SteveBaker (talk) 16:05, 23 December 2008 (UTC)

Steve's right. I'm not going to tell you to switch from Windows to Linux if you're not ready to, but you should understand that the virus problem under Windows is one of the sad prices you must pay for choosing (or being forced) to use Windows. Bill & Co. have taught you that viruses are inevitable, are the sole fault of the nasty virus writers, and are a fact of life that must be forborne, like STD's and bad weather. But all three of those points are quite false. A properly-designed operating system is immune from malware (and it's inherently immune; it doesn't require add-on security products to make it so.) The virus plague under Windows is only partially the fault of the nasty virus writers -- it is also very directly the fault of Microsoft, for actively enabling the possibility of viruses by adding lots of ill-advised features to Windows over the years, and by never taking security seriously until it was much too late. —Steve Summit (talk) 20:41, 30 December 2008 (UTC)

I use Ubuntu myself, but telling Windows users to switch to GNU/Linux isn't going to be accepted by them - they are Windows users after all. --wj32 ^t/c 22:49, 23 December 2008 (UTC)

Just let me ask a question about this virus. The only bad things I know it does are 1) change the behaviour of search sites such as Google and 2) may stop you from getting anti-virus programs so you can delete it. Are there any other symptoms? 60.230.124.64 (talk) 05:52, 24 December 2008 (UTC)

The trouble is that when you have one virus, it isn't long before other malware arrives. The link I provided above, says this virus opens a backdoor into your PC. Such a backdoor enables other malware to be installed without your consent or knowledge, including more viruses, keyloggers and for example linking your PC to a bot-net which will spam many millions of other PC users round the world. Under the burden of all this malware, you PC will eventually slow to a crawl as it expends more and more resources servicing the needs of the malware. Personal information such as bank account details, PIN numbers etc. could be stolen enabling theives to empty your bank account (and if you believe the more paranoid "security experts", use that money to finance people trafficking, terrorism, drugs, etc.) Clean up your PC before it gets any worse.

Skpjack & the Clipper Chip

See Skipjack and Clipper chip for more info
If Skipjack was classified then how could companies use it to encrypt data? It seems paradoxical to me. Plus, is the weakness in that a key is included for each chip or that there's a weakness in the algorithm? Because, if the government were to use the unique cryptographic key on each chip to decrypt the message couldn't they just use the backdoor that was planted in it? --Melab±1 ☎ 16:39, 22 December 2008 (UTC)

"If Skipjack was classified then how could companies use it to encrypt data" They couldn't, but it isn't. I don't really comprehend the rest of your question, sorry! — neuro^(talk) 16:44, 22 December 2008 (UTC)

Classified doesnt mean "government only." If a company were given access to classified information (which many of them often are, see Lockheed Martin), then using it wouldnt be a problem. Livewireo (talk) 17:17, 22 December 2008 (UTC)

Here's how it was intended to work:

• The Skipjack cipher was indeed classified. This wasn't (they said) security through obscurity, but rather just to prevent the design secrets of how the NSA's theory-of-cipher-construction worked (and thus aid the growing civvy-street crypto community to design better ciphers).
• Government contractors (e.g. VLSI Inc.) would make hardware encryption chips (that's the clipper chip) which embodied the Skipjack algorithm, the key exchange protocol, keystorage, and rest of the cryptosystem (modes and stuff, signing)
• Computer manufacturers (IBM, Sun, Dell, etc.) would buy these chips from VLSI and would put them on their board. They'd probably also have a standard API for accessing the chip.
• When you set up your new computer, you'd input (or have it generate) your keys - but you didn't get to pick all of the key. Instead the key was split, with a portion of it (my memory says 22 bits out of 80, but I'm not sure) injected in the VLSI factory (a different fragment for each individual chip). This (the Law-enforcement access field) was kept in the government's key escrow - even you, as the owner of the chip, couldn't recover it.
• You'd pick the remaining bits, and the chip would use the elision of your key and the LEAF for encryption and decryption. Skipjack is a pretty good algorithm - contrary to people's fears at the time, NSA hadn't deliberately released a broken system. The system is secure as long as the government's escrow isn't compromised (you'd hope they'd look after that). Each chip was tamper resistant (which means it'd blow its little brains out if someone tried to get into it), and even if they succeeded (an expensive process) they'd only recover your specific key and the specific LEAF for that chip (no, the NSA weren't dumb enough to use the same LEAF for everyone).
• If the US government wanted to read your encrypted traffic, they'd identify your chip (I think from the exchange of unique chip serial number as part of the key exchange), and then apply to the relevant authority for the appropriate LEAF. That leaves them with 22 (say) bits known out of 80, so they'd have to brute force the rest - but they're the NSA, so they've got plenty of capacity to do that, and knowing the LEAF makes it a very tractable task.
• All in all the system was (if you trust the government) secure (there's no weak key, no trapdoor in the cryptosystem, and no backdoor in the chip). You're relying on the US government not to cock up and leak the LEAFs; say what you like about the NSA, they're not dumb enough to leave a USB stick with all the country's LEAFs on the train.

It's really a very nice system implemented well; the only problem with it was political (that they proposed to make it the only strong crypto that anyone could use). The same principles (secure central escrow, unique local key in tamper-resistent module) are used (and were before Clipper) by the banking industry (and you can bet in military systems too) - the need for a large organisation to be able to recover stuff encrypted by a key stored in a now lost device make some kind of escrow inevitable for them. In addition the British government's Rambutan system (which works much as described above, although still classified and I've no idea if it has a LEAF equivalent) is (supposedly) in use handling non-secret stuff British government departments (the tax office, the health service, etc.). -- AgentOfDoom (talk) 17:59, 22 December 2008 (UTC)

The british thing is Rambutan (cryptography). -- AgentOfDoom (talk) 18:06, 22 December 2008 (UTC)

Upgrading Laptop Graphics Card

Hey guys, I guess this question has been asked a lot of times, but any help would be appreciated. I have a 64 mb nvidia dedicated graphics card on my hp laptop. I find it to be too slow for games and i just wanted to upgrade it to a 256 mb or a 128 mb dedicated graphics card. Is this possible in any possible way on a laptop or should I just consider buying a new laptop? —Preceding unsigned comment added by 69.159.65.57 (talk) 20:36, 22 December 2008 (UTC)

It's possible, but laptops aren't normally made to be user-serviceable, which means you'd have to pay someone to do it for you. Why use a laptop for games ? I suggest you get a less expensive regular PC for that, and keep the laptop for those occasions when you need a computer away from home. You can play some less graphics-intensive games on it on those occasions. Then, when the need arises in the future, you can upgrade the regular PC. StuRat (talk) 20:49, 22 December 2008 (UTC)

Laptops aren't standardized, so good luck finding something that fits. As for paying someone to do it, I have been in the freelance IT business working with various firms for years, and nobody has ever mentioned that they have a skill like that to me. Hm. — neuro^(talk) 00:26, 23 December 2008 (UTC)

I'd suggest returning it to the supplier for an upgrade. Tinkering around inside laptops requires specific skills and it would be safest at the supplier. Sure, you might find someone that claims to be a laptop technician, but if he breaks it, then sure you can sue, but do you want all that hassle? Gaming laptops are currently way overpriced, where you can get similar power for one-third the price in a desktop. So the route people generally go is - build a desktop gaming machine and buy a cheap laptop that can run internet and office applications - unless of course money is no objective. Sandman30s (talk) 11:54, 23 December 2008 (UTC)

I'd say it's highly unlikely that this is possible. When you buy a laptop you should realise that what you get on the day you buy it is what it'll have on the day you sell it. You can MAYBE upgrade RAM and PROBABLY upgrade the hard drive - but often, not even that. Changing things like CPU, audio and graphics is rarely (if ever) possible - and if one small part fails - the whole thing is likely to be junk. I'm seeing this question coming up more and more and the reason is that the 'laptop boom' of a couple of years ago is starting to show up as a bunch of aging laptops that people are ready to upgrade. Deskside computers are not as trendy - but they are the only way to go for upgradeabilty. I've had the same deskside box for 15 years now - yet it's a completely modern, fast, machine with great graphics. I've changed every single part of it at one time or another (either to repair or to upgrade it) - probably the only part that's original is the power cord (and probably not even that!) - but at no time in all those years have I thrown it all out and bought a new one. Laptops are 'all or nothing' things. They are an environmental nightmare because you tend to be tossing out a perfectly good screen/keyboard/CD-drive/battery/power-supply when all you really needed was a new graphics chip - but that's life. SteveBaker (talk) 15:46, 23 December 2008 (UTC)

Actually, if your laptop uses MXM GPUs, it's normally easy to replace them - provided you get a MXM card fitting in the socket =). If you have once in your life assembled a computer, you should get it done in an hour. CPU exchange depends on the laptop, but should normally be doable in half an hour (and five minutes if you own a Compal FL90 series). HardDisk (talk) 23:39, 23 December 2008 (UTC)

Hi i am responsible for a web site and im trying to increase its rate in ranking, So I would like to know what are the main elements that i need to work on for a high ranked site?

For many people it seems keeping high up the ranks is a near-full-time job. 194.221.133.226 (talk) 09:31, 23 December 2008 (UTC)

There are many tricks - and lots of books and services (all highly dubious) relating to boosting your Google page-rank...

...or you could resort to honestly trying to make your site more useful. Having content that people actually NEED is the way to get yourself up there in the rankings. If your site is a business - see if you can find some content that would be useful to other people in the business. If you sell mortgages - make a little JavaScript mortgage cost-over-time calculator - if you are a builder, put a house price estimator up there...little things like that (if done well) will cause other people to link to them - those links are what push up your page rank score. The other tricks people describe only work until Google manage to tweak their code to defeat them...and many of the tricks fail because they've already been defeated.

Case in point - the MINI (BMW) car company printed a one page advert on the back of a German car magazine. If you have a webcam and go to the German MINI web site and hold the magazine advert up to your camera - a 3 dimensional model of a MINI Cooper car pops up in the image coming from the camera - sitting on top of the advert!! As you turn the page around, the model car appears to 'stick' to it. This is an incredible thing. Will it sell more cars because people look at the car in the camera? Perhaps a few. But will it push up their page-rank? Hell yes!!! When every geek site on the planet finds out about this amazingly cool thing - there will be links from every high-valued car nut site on the planet! (One such linking site is here for example). It's only been out a few days and already, if you Google "webcam MINI Cooper advert" you get 51,000 hits (and you can bet that every single one of those links to it).

It's amazing the content that people will link to - so put up pages about the history of the city you're centered in - cake recipes 'donated' by your employees - make a "Keep your kids amused while you <do something with the product>" page as an excuse to put up word-search puzzles containing words related to your business - optical illusions - things kids can print out, cut up and fold into a 3D model. Put up anything that people will actually find INTERESTING and/or USEFUL. If this content is too costly for your team to produce - consider offering free web space and a free domain name on your server to your employees for them to put up interesting content (but obviously monitor it for inappropriate stuff) - have your IT department run free courses to teach them how to do that (web-savvy employees==a good thing!). Offer prizes to the employee who's website comes highest in the search listings when you type your company name into Google. Heck you're a university - let the students have pages - with competitions for best content, etc, etc.

Because every one of their web sites will link to your web site (and presumably host a FREE banner ad!) - your page rank will improve. If you believe in your product - put up an open forum system for people to discuss it...sure, they'll say bad things as well as good (but surely you should want to know that) - but good or bad, they'll make links - which is what you want. The growth in link-count will be slow but steady - your slow climb up the rankings will be permanent and not subject to the vagaries of exploiting 'loopholes' in the Google code.

Making the Internet a better place by providing more good stuff that people actually WANT to see is a vastly better and more ethical way than trying to trick the search engine into displaying a poor link (your site) ahead of one that should be considered a better place for people to go when they type in that particular set of search criteria.

If you can't find them on your keyboard through use of shift/ctrl then you can always use Alt keycodes to get them.

Cheap media player for home theatre

Hi all. I'm looking for a cheap but decent media player for a home theatre setup. Mostly it would be used for watching TV series or movies from a central PC in a different room. To cut a long story short I'll most probably buy an Xbox 360, it seems to fit my needs quite well. I'm just asking out of curiosity in case there is something substantially cheaper out there. Basically it needs to have the following:

1. 1080p upscaling + full 1080p decoding capability
2. 5.1 or higher surround sound capability
3. HDMI interface
4. USB 2.0 support for plugging in an external drive or flash drive
5. DivX/Xvid (and all those other funny codecs optionally)
6. LAN but much more preferably wireless LAN
7. Easily (W)LANable with Windows XP without too much hassle
8. DVD drive (or Bluray)
9. (Optional) hard drive
10. Substantially cheaper than an Xbox 360 Arcade with WLAN attachment

I think points 2 and 3 rule out a cheap PC alternative. HDMI sound and graphics cards are not cheap. So we're looking at a dedicated all-in-one media player type solution. There are a plethora of them out there but I'd appreciate if you could link to something you've personally used or seen in action. I know what I'm getting with the Xbox (I've seen it in action at my friend's house, 2 Xbox 360's + Vista PC happily networked and sharing folders) so I want similar confidence of first-hand knowledge with any other system. Thanks! Zunaid 14:08, 23 December 2008 (UTC)

No, you have it right. The Xbox 360 and either the windows media tool, or the free TVersity tool can do what you want. Building a PC (even buying used parts) would easily cost more than the $199 you can get an entry level Xbox 360 for. Look for a 802.11g wi-fi bridge (usually around $25) instead of the official adapter and you will save a bunch. No other media device comes close, considering the relative difficulty of 1080p stream decoding. Oh, and 2 and 3 on your list are irrelevant on a PC, DVI is ubiquitous and easily adapts to HDMI with a $4 part, and 5.1 audio output from a PC is also standard even with all-in-one motherboards. Still, by the time you get enough CPU and GPU power into the box to do what you want you will have spent a lot more than $200. --66.195.232.121 (talk) 19:22, 23 December 2008 (UTC)

It's worth noting that the xbox won't allow you to plug big external drives in. I've had no problem with my 4gb thumb drive, but my 320gb external hdd isn't recognised by the xbox at all.

Program to show how to fold a origami

I want to write an instruction sheet of how to fold a simple origami. I thought first about taking pics as the origami takes shape, however, I thought that a drawing would be more clear.

What program could I use to fold a (virtual) sheet of paper and take screen-shots of every step? Mr.K. (talk) 17:59, 23 December 2008 (UTC)

a) Any graphics program you use to fold your virtual sheet of paper can also save the resultant image.

b) Screen shots do not require a program. On Windoze, ctrl-"PrintScr" (or whatever the key to the immediate left of the scroll key is called) captures a screenshot to the clipboard, which you can then paste into your favorite graphics program. Use alt-"PrintScr" to capture only the foreground window. -- Fullstop (talk) 18:40, 23 December 2008 (UTC)

Certainly a 3D modeling program would let you do that - you could use Maya, 3DStudio (both of which are going to cost you $1000 or so) - or you could try using blender - which is free. However, when I've tried to do that exact thing - the results were less helpful than you might expect. The problem is the very mathematical perfection of the computer modeling process. For example - if your first step is to fold the paper in half...in a photo of the resulting folded sheet - you'd see two layers of paper sitting on top of each other - the top one slightly curved and the fold being a bit less than 180 degrees. When you do it in the computer - the resulting fold is a PERFECT 180 fold - so the resulting image is a flat rectangle that looks like you took your original paper square and cut it in half - rather than folding it. For such a simple case, you can instead tell your 3D modeler to fold the paper through 179 degrees...this works pretty well - you can now see that there are two layers of paper after folding it. But now, suppose you want to fold it again - at right angles to the first fold...well, the 179 degree trick doesn't work because the second fold pushes one sheet 'through' the other inside the computer - and the result is a mess. You can kinda fix that too by pushing vertices around in the modeler - but by the time you get to something of the complexity of a paper crane...it's beyond your manual ability to keep it under control.

So actually (and disappointingly because I'm a 3D computer graphics fanatic) - I have to recommend that you stick with photographing your work step-by-step. SteveBaker (talk) 21:46, 23 December 2008 (UTC)

Bypassing IE Active X for Lightbox JS

When using Lightbox (JavaScript) javascript to create an online photo gallery, Internet Explorer will restrict the "script or Active X controls" and hence, not allow the photo gallery to work until the users clicks "Allow Blocked Content." As a result, the photo gallery will not display properly if the user does not click this. Is there someway around this? Could one automatically allow IE to not block the script? Acceptable (talk) 18:38, 23 December 2008 (UTC)

It might be inconvenient, but unfortunately there are some dishonourable scumbags out there who would exploit getting round the Active X script restrictions to drop viruses, malware, rootkits and all manner of other nasties on your PC without your consent or knowledge. However, the individual user can degrade the security settings of Internet Explorer through the internet options (security tab), but you would be hard pressed to find anybody daft enough to do that.

You could pay for a VPN in the US. Or even a proxy. If you pay for it they're more likely to have enough bandwidth. There's no guaranteee this will work though.

Dosbox

What is with Dosbox? There are a couple of games that work in XP and Vista without Dosbox, so why use Dosbox, even if there are many other games that will only work in Dosbox? Why can't we just get an old computer (if we can) and use it to play the games? Because, as one person said, "It's just not the same using Dosbox as it is the real thing." 60.230.124.64 (talk) 21:50, 23 December 2008 (UTC)

You're not being very coherent. Most older games don't work correctly on modern pcs running XP or Vista. Why go to the trouble and possible expense of having a separate PC with older architecture running DOS 6.22 and Windows 3.11 when you can simply run Dosbox on your current PC? Exxolon (talk) 22:39, 23 December 2008 (UTC)

(ec)DOSBox works for MacOS and Linux as well as Windows. (Also "Palm OS, PlayStation Portable, Internet Tablet OS 2008, and the GP2X, on various computing architectures including PowerPC, SPARC, MIPS and ARM") People using a computer with a Mac or Linux operating system can thus use DOSBox to run DOS programs without needing Windows. Even for Windows, the assumptions about how the system is set up (e.g. single-user versus multi-user, differences in peripheral hardware in 2008 versus 1993, etc.) mean that it is not always straightforward to map a DOS program onto Windows. While Windows does try to be backward compatible with DOS, modern (post Win98) Windows versions are based on the WinNT kernel, which, despite the name, is substantially different from the Win98 (basically DOS) kernel. Compatibility with DOS programs (especially those, like games, which expect to be able to monopolize the entire system) sometimes becomes difficult, and supporting them is frankly not a high priority for Microsoft, as running 10-year old games is not something most people do. Companies re-releasing old titles thus find it cheaper just to use the free emulation system provided by DOSBox, rather than spend the time and effort troubleshooting potential compatibility issues. Finally, it is not always possible or convenient for someone just to buy an older system. You're right that it's not the same using a emulator versus using the actual hardware, but for a number of people it is "close enough". -- 128.104.112.113 (talk) 22:44, 23 December 2008 (UTC)

You use DOSBox if you don't have an old computer around (and don't want to spend all the time getting its hardware working correctly with your game of choice), if the game you want doesn't run on your current computer, or if you don't have a PC. If you don't fall into those categories... don't use it! --98.217.8.46 (talk) 02:26, 24 December 2008 (UTC)

cross-browser display issues... :(

My website (link, and please no comments about the quality, it's still in progress) is having some issues displaying properly in various browsers. In Firefox it displays fine :) . But it Google Chrome, the rounded corners do not display properly. I use the -moz-border-radius-20px thing; any idea why this doesn't work in Chrome (and how can I get it to work)? And another thing - the ad(s) don't display in Firefox and Chrome, but in IE, that's all that loads. I see that ad, it loads... And then it just says "loading" on the bottom bar, but it never loads anything but the ad. This happens in IE6, 7, and 8. Any ideas? flaminglawyer^c 05:20, 24 December 2008 (UTC)

Two issues: first off, google chrome by default works off font types from Macintosh. I would be willing to bet your font doesn't look right on Firefox Macintosh either.

They replied, 'yes, its working fine - your just not visiting any dangerous sites.' (They didn't say those word exactly but that what they meant). So my question is, should I renew my subscription?

Delphi 2009 Resources

Does not the new Resource Manager in Delphi 2009 work? I am writing a multiline text edit control, and want to use some own cursors (*.cur and *.ani). I have added the cursors to the component's project (as cursors) via Project/Resources. In the code, I have added constant declarations such as

const
  crBlock = TCursor(11);

and then, in the component's Create constructor, I try

Screen.Cursors[crBlock] := LoadCursor(hInstance, 'ARBLOCK');

where ARBLOCK is the resource identifier of the cursor. However, the cursor cannot be used, and Windows' GetLastError reports ERROR_RESOURCE_TYPE_NOT_FOUND = 1813. What have I done wrong? --Andreas Rejbrand (talk) 11:49, 24 December 2008 (UTC)

Google word distance

Is there some way I can do the following Google searches ?

1) Find all pages containing "flagrant" and "foul" where the two words are in the same sentence.

2) ...where the two are within 10 words of each other.

I'd like to find both the phrase "flagrant foul" and sentences like "that foul was most the flagrant I've ever seen". However, I don't want to find a dictionary page with all the F words listed. This is just an example I pulled out of my head, but I often want to do this type of search. StuRat (talk) 15:46, 24 December 2008 (UTC)

http://www.google.com/advanced_search is as good as it gets. No 'near:10' keyword or anything like that.

But (in my experience), word proximity does carry weight in Google indices, so a search for fragrant +foul should give you decent hits after you've skipped all the dictionaries. (Indeed, when I tried that, no dictionaries appeared).

Have a good Christmas. -- Fullstop (talk) 16:10, 24 December 2008 (UTC)

Assuming that you are running the new version 8.x ... go to tools ... advanced settings and add your exception to the PUP's. One other note in defense of AVG: at one time (ver. 7.0) they did not have the best detection rate - that improved with 7.5, and improved GREATLY with 8.0. 8.0 also now detects spyware as well as viruses - a plus in my opinion.

I seem to be a Digg Popularity Jinx. Why?

I can't even get the viral video Here It Goes Again by OK Go to hit Digg's front page

I've submitted stories NUMEROUS times in hopes of making them popular on Digg. (Okay, some of them weren't so serious.) However, I knew something had to be really wrong when I tried to submit the original video of Here It Goes Again.

The viral video has over 42,000,000 hits on YouTube and yet, it does not achieve "popularity" (i.e. a front-page appearance) on Digg.com. Why? Was it because I submitted it? Whereas conversational delivery may depend on one's vocal intonation, body gestures, vocal pauses, eye contact, and other finer nuances of socializing, none of this applies when one submits a story on Digg.

I was surprised that no one submitted this viral treadmill dancing video long ago, so I decided to take the initiative.

Why does it only have four Diggs right now? Where did I go wrong? --Let Us Update Special:Ancientpages. 19:04, 24 December 2008 (UTC)

42,000,000 hits? It may be considered old and boring by now -- with that many hits, all of Digg has probably already seen it. --Carnildo (talk) 22:23, 24 December 2008 (UTC)

Now it's 42.5 million. The view-counter keeps climbing fast, and users still comment every 30 minutes on average. Moreover, I've watched it numerous times and still won't get bored by it. I'd say it's still very much as popular as it was when the vid first went viral. Perhaps the title and message summary needed to be made a certain way? If so, what way? --Let Us Update Special:Ancientpages. 11:16, 25 December 2008 (UTC)

It's just not new or novel - I saw this video AT LEAST 4 months ago. Sites like Digg want new stuff that not too many of their readership have seen yet.

Why did a new modem not fix the problem?

Monday I had been online only a few minutes when I couldn't get into some web sites, and then I couldn't get into any.

On one occasion when I lost the Internet, a call to tech support was answered with a message that the phone company had been having lots of problems. I didn't get the same message yesterday, but it had been quite windy.

The tech support person suggested my problem might be a 15-foot cord. I told the installer in August where I wanted to put the computer, and the nearest phone jack required a 15-foot cord, or however long it was. The tech support person said the modem could go anywhere and I could get a longer cord to connect it to the computer, but from the modem to the phone jack could only be 10 feet.

I decided to try this, since the installer gave me a bunch of extra stuff. In fact, due to my inability to effectively communicate, an earlier call to tech support resulted in my getting a new modem sent to me. The old modem was supposedly fine. But I decided to hook up the new one. The cord to the phone jack was shorter and sturdier. The cord from the modem to the computer turned out to be long enough. I also noticed what could have been a problem: the power cord for the old modem had a chair leg sitting on it! I used that one anyway because it never seemed to have any problems. Even though it was as flimsy as a twist-tie on a bread loaf.

The Internet came right back and worked fine for an hour or so! I had to sign up again for the Internet (or maybe I didn't). Somehow what I did may have brought the Internet back. And maybe it was something the phone company had fixed and then something else went wrong.

I did notice the power light on the modem blinking, which it wasn't supposed to. Not for long, though. Just in case, I later switched to the power cord that came with the new modem. When the Internet went out, I called tech support again and was told they were so busy they might not be able to get someone to come to my house until the next day (possibly another hint of outside trouble). I later tried switching back to the old modem, and that helped very briefly. Or it was a coincidence. I know I was seeing one or two brand new pages with updated information.

I have some evidence the problem was on the outside. There's a page I was sent to once where I'm supposed to see green if the Internet is working and red if it isn't. Under "USB" the long, complicated number was red. The other two numbers were green during the final hours, but one was red at one point.

One thing I forgot about was unplugging my modem, turning off the computer, turning on the computer, and plugging the modem back in (when weather was a problem before, people were told to do that even though the outside problem had supposedly been fixed) . They always tell you that when you call tech support, before a real person ever answers the phone. It worked! I had done all the various things that are supposed to help fix the problem earlier, but I feel certain the problem was on the outside. It can't all be coincidence.Vchimpanzee · talk · contributions · 22:30, 24 December 2008 (UTC)

I knew I'd forget something. The reason I returned to using the old modem. Although the Internet seemed to be working fine for that hour or so, the light which blinks in an irregular pattern never seemed to be on at all on the new one. The one which, if I see a page is slow to load, comes on at the precise time the page finally loads.Vchimpanzee · talk · contributions · 22:37, 24 December 2008 (UTC)

Laptop video driver problem

I have a Dell Inspiron 1501 with Microsoft Windows XP Media Center. I had to reinstall XP and then my screen was blurry and looked like it had been stretched horizontally. So I installed the video driver off of dell.com. The computer became super-slow. So I System Restored and tried again, only to gain the same result. Try a third time, only to get the same result. I am trying to keep this laptop until Windows 7 comes out, so should I replace my graphics card or what? mynameinc 15:40, 25 December 2008 (UTC)

The "blurry" horizontal stretch is likely a result of the software using a standard 4:3 aspect ratio while the display is widescreen. Since windows generally will not allow you to change these settings without a proper driver installed, you need to update the video/display drivers. Installing the correct driver should *not* cause the system to slow down. I would suggest searching for alternative drivers (such as the original driver CD, if available, older/alternate versions on dell.com, or more generic/specific video drivers). You might also check that you have hardware acceleration enabled (Start->Control Panel->Display->Troubleshoot). Finally, you can adjust some visual performance settings in windows to minimize the slow down (Start->Control Panel->System->Advanced->Performance->Settings->Visual Effects). —Preceding unsigned comment added by 76.11.230.33 (talk) 18:09, 25 December 2008 (UTC)

Proprietary Programming Language

Are programming language copyrighted or patented? --Melab±1 ☎ 19:58, 25 December 2008 (UTC)

Copyright law is not applicable to programming languages, as they cannot be copied. How would you create a copy of "c"? However copyright is applicable to compilers, standards or manuals which are protected by default. Their authors may relinquish copyright explicitly (put them into the public domain), or they might spread them using free licenses like bsd which effectively disables copyright from a practical point of view. The actual situation on compilers and runtimes is mixed, even for the same language. —Preceding unsigned comment added by 84.187.72.95 (talk) 01:19, 26 December 2008 (UTC)

The point is though that if someone claims a copyright and its never been tested in court then really the only answer we can give is maybe. It's always a bit dubious to say "Well they never sued so they can't have really believed they were right since 1) Particularly if your talking about open source software the gains from a lawsuit have to be weighted up againt the PR disaster 2)) Ditto if its propriety but a small company 3) The nature of copyrights means you can if you want allow people to use something so it gains in popularity then start the lawsuits once it has.

Amazon's user reviews are pretty good too. Just don't go by the 5-star scale.

Judging by the amount of material that goes out under his name, David Pogue is most likely an organization. The organization has put out some useful books on computer use. Its gizmo reviews in IHT, when I bother to read them, aren't so impressive. Pogue is fond of reviewing cameras and the like, but there's little or no suggestion that Pogue is more than the most casual photographer. Yes, what I want to see are reviews based on user experience, and more particularly the experience of people who are willing to read instructions and put some effort into following them, but who don't imagine that photograph-worthy scenes will hold steady while the would-be photographer futzes around in some menu system for the appropriate options. I've found that reviews worth reading are often found among the dross, boosterism and backbiting within the forums at photo.net. But there doesn't seem to be anything interesting there about this particular camera. You could of course ask there or at some other forum: say what interests you, and be tolerant of answers that miss your point. Morenoodles (talk) 09:11, 26 December 2008 (UTC)

http://mydomainname to ghs.google.com

In order to make my Google Site display when someone enters www.mydomainname.nl, I had to make a CNAME record in the DNS records directing to ghs.google.com. When someone enters mydomainname.nl however, they are directed to a page from my webhost (the browser adds http:// to make http://mydomainname.nl) - what CNAME record should I make to enable direction to ghs.google.com? ----Seans Potato Business 00:48, 26 December 2008 (UTC)

The answer is you can't create a CNAME record for your root domain [6]. Technically it is possible [7] but this would require the set-up at .nl be different. You'd need to use a transparent redirector to achieve what you want to do. You might want to look and see if your DNS service provides it. Some do. (Mine does.) There are also free services, without ads, but as you're using their servers it may not be a good idea if you need high uptime/mission critical work. Also you could run the redirector yourself. If Google Apps was set up to allow you to use A records instead of CNAME you could do it but for the free one, I'm pretty sure your not (from memory). Nil Einne (talk) 10:18, 26 December 2008 (UTC)

My domain registrar is starthosting.nl - I found redirect settings in their domain management features and set "default" to redirect to the www. subdomain of my domain. This had the desired effect but I don't know if there are any unanticipated repercussions. I think it's particularly confusing that the address is given as "default" and not "mydomainname.nl". Anyway thanks; it's working now. ----Seans Potato Business 05:54, 28 December 2008 (UTC)

I can't say for sure but I suspect the only issue is that you are likely relying on their services to handle the redirection, in other words as mentioned above if their redirection service goes down, anyone trying to access your domain through mydomainname.nl will get a server 'not responding message'. Also default may include wildcards for that domain, in other words if you try somesubdomainthatdoesntexist.mydomain.nl you will also be redirected to www. You could look at the NS records for you domain to get an idea of whats they're doing. If you want you could e-mail me your domain name and I could take a look but I only know as much as I leartn when setting up my domain for personal use and that was a while ago.

Video Card RAM

I have an ancient computer with an 8MB video card. The comp has 224MB of ram. How powerful a video card can I put in this "computer"?--AtTheAbyss (talk) 05:28, 26 December 2008 (UTC)

moved from RD Misc Nil Einne (talk) 10:20, 26 December 2008 (UTC)

We don't have enough information to answer your question completely. Your video card could be AGP or it could be PCI. There's even a possibility it could be VESA Local Bus. It's even possible you don't have a discrete video card but onboard video (although this seems unlikely to me since a computer is far more likely to have 224MB ram then 232MB of ram which is what it is likely to have if you have onboard video and 8MB is dedicated to the card. But whatever the case, the answer is likely to be 'not very'. Nil Einne (talk) 10:28, 26 December 2008 (UTC)

Moreover, even if you could use a fairly powerful video card with the computer, the rest of your hardware would be bound to become the bottleneck for performance. -- Captain Disdain (talk) 14:16, 26 December 2008 (UTC)

It is an SR9 (AGP) video card. I understand I'm grasping at straws here, but I have a ton of games that ran on my old comp, but can't be run on this one, and if I could install just a 24 or 32mb or something that would be pretty cool.--AtTheAbyss (talk) 17:07, 26 December 2008 (UTC)

The memory capacity of the video card doesn't affect whether you can install and operate the card. It's possible that with so little main memory that games and such will drop down to poorer quality graphics than the card could otherwise handle - but that would be different for every application. The only real restriction is the graphics interface bus. If you have AGP then you should still be able to find compatible cards fairly easily (although the modern standard is PCI-Express - which you presumably don't have). I agree with Capt.Distain though - spending a lot of money on a graphics card for such an ancient machine is likely to be a waste. I would look for a used AGP graphics card on eBay - something with maybe 128Mb of graphics memory. Don't spend much! SteveBaker (talk) 00:51, 27 December 2008 (UTC)

Um if the computer is so old which it is, I highly doubt the computer has a AGP 4x port. Most likely it's 1x or 2x. Most/all modern AGP cards are only backwards compatible to 4x because of the difference in signalling voltages, take a look at Accelerated Graphics Port for details. It looks like you should be able to use (in theory) certain Radeon 9800 cards as well as all 9700 cards. These aren't actually too bad cards and you could probably play (if you don't have too high expectations in frame rate and quality) most games at least say 3 years old with these cards but as others have mentioned your computer is likely to be a bottleneck. Also if your AGP bus is only 1x that will be a bottleneck as well. Most importantly perhaps, finding one for a decent price is likely to be rather tricky. Particular the 9800 since you have to make sure you get the right one. All in all, as with others I wouldn't recommend you spend much money. Nil Einne (talk) 09:08, 27 December 2008 (UTC)

What percentage of the WP database is devoted to articles and what to all the rest? And has this percentage changed over the years?

Would I be wide of the mark in estimating about 1%? When I think of all the talk pages for the articles, the massive history sections which store every edit ever made to every piece of text, the User Talk pages, all the archives, and these research desks and other stuff, I start to wonder how many bytes of data are being stored, and where.

And yes, it will change - originally we were probably nearly all project-space, then we got way more articles. As our number of users increased, we got more user pages and more talk pages, as well as more articles, but the article number again dropped below the non-article number. Now we have 47,764,014 users, so we have far too many userpages and non-articles. We really need to cut down on all this stuff.

It's sort of sad that the #1 "re-usage" of Wikipedia is for things like this, but it's not unexpected. They are not always within the constraints of the GFDL so they aren't necessarily within the letter of the law but there's nothing inherently wrong with Wikipedia content being used in this way. --98.217.8.46 (talk) 03:20, 27 December 2008 (UTC)

One or two seek to be 'the new wikipedia' by eliminating one or more of wikipedia's perceived faults (eg they might eliminate the notability requirement for new articles) - or by adding some new capability (eg only presenting articles that have been 'approved' in some manner). But the vast majority are simply seeking to get ad revenue from people visiting their site using our content. These sites are actually legal - under the GFDL - providing they acknowledge Wikipedia.

Convert DVD video to AVI (or mpeg)

Okay, I know I'm going to come off sounding lazy ... and you're right, I am. Anyway, I'm wondering what is currently the best (preferably free) program to use to rip the video from a DVD to an .avi file. I've already looked at wikiHow's way to go about it, but it really didn't want to work on my computer. And in case you're wondering, I'm wanting to rip The Dark Knight to my computer to put in on my Zune... I know I can just .torrent it, but I'd like to save some time rather than downloading it then converting it to mpeg. –  LATICS  talk  07:37, 27 December 2008 (UTC)

There is no way to answer what is the 'best' program since it depends what you mean by best. There are so many programs and combination of programs that IMHO it doesn't matter that much anyway. Personally I would recommend either Mplayer, VLC or Megui Nil Einne (talk) 09:34, 27 December 2008 (UTC)

There are lots of good programs, as Nil Einne says, and you'll often need to use several combinations of programs to get good results. Some of the best in my experience are AutoGK, HandBrake and MediaCoder. For a simple way, you first need to decrypt the DVD, use either AnyDVD or DVD Shrink for this. Then use an encoding program to convert the .vob to avi, AutoGK is an easy to use tool but isn't being developed much anymore. HandBrake is another good tool and has many more options that AutoGK. Remember to set the right codec and output container for Zune as Handbrake defaults to x264 mkv which might not be compatible. There are lots of in depth guides and more programs over at the doom9 forums. SN0WKITT3N 13:25, 27 December 2008 (UTC)

Have you tried the PowerDVD player ? It seems the best, in my opinion. For other players, they may be on a secondary audio channel that, for the DVDs you tried, is blank. You may be able to manually select the audio channel. Also, check your PC's volume settings. Make sure none of your volume settings are at zero and none of the mute boxes are selected.

Simple and accurate way of retrieving the size (in bytes) of a dynamic array in Delphi

I have defined an record type, containing a number of dynamic arrays (of strings, integers and another record containing simple values (strings, integers and boolean values)), and then I have defined a new type as a dynamic array of this record. Thus, I got

type
  StringArray = array of string;
  IntegerArray = array of integer;
  
  TMySmallStruct = record
    A: integer;
    B: string;
    C: boolean;
  end;

  TMySmallStructArray = array of TMySmallStruct;

  TMyStruct = record
    Alpha: IntegerArray;
    Beta: StringArray;
    Gamma: TMySmallStructArray;
  end;

  TMyDataType = array of TMyStruct;

Now I need to find the size (in bytes) of an particular instance of TMyDataType. Thus, I have

var
  FMyData: TMyDataType;

and I want to find the memory (in bytes) occupied by FMyData. I cannot simply use

MySize := SizeOf(FMyData)

because FMyData is an dynamic array, and thus of type pointer, so that MySize = 4 for all instances of TMyDataType. Of course I could iterate over all items of type TMyStruct, and add all sizes, and to obtain the size of one particular instance of TMyStruct, I can add the sizes of the members, which for each can be obtained as the size of all items in the array, but this is a very lengthy approach. Is there not simple way to obtain the size of a TMyDataType instance? --Andreas Rejbrand (talk) 17:28, 27 December 2008 (UTC)

SizeOf(TMyDataType) or SizeOf(TMyStruct)? Sorry if it doesn't work, as I don't know Pascal/Delphi. [8] --wj32 ^t/c 21:17, 27 December 2008 (UTC)

No, that does not work. The size of a particular FMyData variable is in general not equal to the size of another variable of the same type. --Andreas Rejbrand (talk) 21:27, 27 December 2008 (UTC)

I don't understand what you're saying. I'm assuming TMyDataType is some sort of typedef, and FMyData is a dynamic array with elements of type TMyStruct. Couldn't you just find the size of TMyStruct and multiply it by the length/number of elements of the array? --wj32 ^t/c 23:03, 27 December 2008 (UTC)

Or... do you mean the size of TMyStruct, counting the dynamic arrays it contains as their actual size as opposed to the size of the pointers? I'm pretty sure there's no (easy) way to do that, and I can't imagine why you would want to do that either. --wj32 ^t/c 23:08, 27 December 2008 (UTC)

Yes, I think you've got it right. Actually, FMyData contains my text editor's undo memory, and as a TMyDataType it is an array of "snapshots" of the file, each snapshot corresponding to a TMyStruct variable. A TMyStruct contains all lines in the file (at that point) as a dynamic array of strings and other data associated with each line (e.g. font). I simply want to tell the user how much memory is freed when the undo memory is cleared. --Andreas Rejbrand (talk) 23:33, 27 December 2008 (UTC)

Is there really no simple way to get this size? --Andreas Rejbrand (talk) 16:22, 30 December 2008 (UTC)

RCA to Digital Media Port

I have an older CD player (Kenwood CD233) which I used to connect to stereo system in the house. We have since acquired a DVD Home Theatre System (Sony HDX-900W) which controls the TV sound and plays the DVD's. The CD player holds 200 CD's, which is quite handy - but I can not locate any corresponding input jacks on the HTS to plug it into. The CD player only has the older RCA (left/right) output jacks and the DVD player seems to only have Digital Media Ports available. Is there some sort of adapter I could obtain to connect RCA to Digital Media?142.68.221.163 (talk) 21:45, 27 December 2008 (UTC)

I can't find any Digital Media Port adapters that work that way, however the manual (via the Sony Support Canada site) indicates that there is an input on the front panel that will take a stereo mini-plug. You should easily be able to find an adapter that has two RCA jacks on one side and a mini-plug on the other. It should be a very low-cost item, as opposed to the DMP adapters. Alternately, it looks like you could use audio jacks of the SAT/CABLE input on the back, unless you've already got something else connected there. --LarryMac | Talk 14:25, 29 December 2008 (UTC)

Try booting into safe mode [15] and installing the OS upgrade again (while its in safe mode). If it was an OS upgrade. I don't see how unplugging a computer while downloading a file would permanently screw it up; it's probably filesystem corruption then (very unlikely though). --wj32 ^t/c 05:21, 28 December 2008 (UTC)

I don't know what file system OS X uses, but file system corruption can occur if the power is unexpectedly cut. The probability depends on the file system used.

Yes, and surely HFS+ doesn't use delayed allocation as much as XFS does (I use XFS)? I've had one or two power outages with XFS, but the worst that has happened is certain files I was working on got filled with nulls.

Checking system time in batch file

I would like to know if it is possible (if so, how) to write a batch file in such a way that it executes a desired command at a specific time?

There's a command called at that does that. It uses military time. So, if you wanted to start the command prompt at 9:22 p.m., you'd type this into a batch file:

at 21:22 cmd.exe /interactive

But, as you may have guessed, you probably don't even need a batch file to run a command on a schedule. You can just type the command above.--Djnghfg (talk) 04:24, 28 December 2008 (UTC)

Deleting option from Windows boot loader

I recently installed Windows XP to a second drive within my PC to determine whether the installation was the root of an Internet-connectivity issue. Since it was not, I would like to remove the installation. I have already deleted the Windows folder from that drive, but when the computer boots, two options are still presented (a choice between booting the original installation or the newer/deleted installation). How do I restore order? Thanks ----Seans Potato Business 05:51, 28 December 2008 (UTC)

It depends on what OS created the boot loader. If it's Vista, you'd use the BCD command. If it's XP, you can open up the boot.ini file located in the root of your primary partition with Notepad. It's a hidden file, and it's read-only. But once I know your primary OS I can give you more detailed instructions.--Djnghfg (talk) 06:02, 28 December 2008 (UTC)

Thanks. The primary OS is WinXP but I have been unable to locate a boot.ini in the root of any of my partitions, neither in the GUI (hidden files made visible) nor with a CMD DOS-style prompt. My original and present WinXP installation is on the D: drive, while my recent installation went on the C: drive. However, according to the Windows Disk Management utility, C: is system and D: is boot. I appreciate any help offered. :) ----Seans Potato Business 17:08, 28 December 2008 (UTC)

That's because boot.ini is marked as hidden and system. Turn "Hide protected operating system files" or whatever it is off (it's in the same place you turned on hidden files). To actually modify the file, run: attrib -s -h -r C:\boot.ini (you can skip the previous step if you do this). Open up Notepad and change it, and when you're done, run attrib +s +h +r C:\boot.ini. --wj32 ^t/c 23:20, 28 December 2008 (UTC)

Oops, I just noticed you said D: is marked as boot. Well, change C: to D: in my instructions. --wj32 ^t/c 23:21, 28 December 2008 (UTC)

Nonetheless, the boot.ini file was on C:\! I changed the default setting and deleted the superfluous indication. Thanks very much. :D ----Seans Potato Business 10:20, 29 December 2008 (UTC)

GPRS/GSM tracking

This maybe sounds odd, but I've heard of somebody who geographically tracked another person's mobile phone by using it's GPRS/GSM signals, by only knowing the phone number. Thus effectively locating the person in question. This is likely false, or it could be done with some (possibly illegal) device? Is this technically feasable? Or there is some paid website which offers such a service? Thanks in advance. --Rev L. Snowfox (talk) 08:45, 28 December 2008 (UTC)

It's very well possible, I believe that over here (Poland) the police forces have such equipment. SteveBaker will definitely know more :) --Ouro (blah blah) 10:38, 28 December 2008 (UTC)

But I guess these kind of devices are illegal to be owned/used by civilian people (outside of military/police/other authorities), and they can't aquire these legally. I wonder if it is legal in the Netherlands...? Probably not. I know that GSM service providers (and thus police) can locate people by cell information (but that can mean a wide or narrow area too), but what I specifically heard is about GPRS data remotely being tracked, from a considerable distance (well, 1000+ kilometers). Possibly with some kind of satellites involved. But yeah, maybe it's a hoax, prank or such. I just don't know because I'm not a telecommunications expert nor a specialist policeman/military technician... But it keeps me bugging. --Rev L. Snowfox (talk) 20:14, 28 December 2008 (UTC)

This was used to assassinate a rebel leader in Columbia albeit this was with a satellite phone [16]. However you are wrong about 'just needing to know the phone number'. You really need the cooperation of the mobile service provider. Also the phone needs to be own and transmitting/receiving a signal to a base station. This may not be a problem for law enforcement agencies with warrants, but is not something some random person can do. If you install your own base stations you may be able to track a specific account but this would likely require you are able to identify the phone which again may not be possible without the cooperation of the service provider. Most GPS devices are one way. If you have something like a personal locator beacon and it's sending a signal then obviously anyone capable of receiving that signal will know where you area. Nil Einne (talk) 11:27, 28 December 2008 (UTC)

Surprisingly, it may infact not (always) need the cooperation of the mobile service provider; a few weeks ago I saw reports of an FBI system which did cellular phone tracking (in specific areas) by having special fake "cell" towers that partook of only the initial handshake part of the phone/cell connection protocol. These things would announce themselves as available cell towers, and all the phones in the area would respond (with their IMEA numbers) allowing the FBI to identify (and with a couple of diverse antennas triangulate) the location of all the responding phones. The article gave no indication as to how the FBI deployed this technology; one would imagine it would be a number of mobile units. 87.113.77.112 (talk) 17:51, 28 December 2008 (UTC)

NNTP server software for small group message exchange

Can someone suggest a simple (meaning easy to install and manage) NNTP server app for small group collaboration? The server will be hosted locally and will not be exchanging messages with other servers. It only needs to have basic features and should not consume a lot of resources. --173.49.9.242 (talk) 15:00, 28 December 2008 (UTC)

I don't have a good answer to your question (apologies), but can I ask you a question? Why NNTP, specifically? Don't get me wrong, I love NNTP, but it's sort-of an antiquated technology, and unless you have extremely techy users, I'm pretty sure that they'd be much more comfortable with either a mailing list or a simple web forum. Almost certainly the software for those things will be much easier to install and to maintain, in addition to being much more frequently updated. There's very little semantic difference between a news-group and a mailing list.

However, just for the hell of it, I made a search in the ubuntu package database, and indeed, there are something that might suit you. See packages nntp, cnews and cyrus-nntpd-2.2. Obviously, I have no experience with any of them, but you might be able to figure them out. Belisarius (talk) 19:04, 28 December 2008 (UTC)

For collaboration, I find it sometimes helpful to preserve the discussion that lead to a decision. Many NNTP clients have good built-in threading and rule-based message handling capabilities. I find web-based message boards less easy to use and take more effort to navigate. NNTP may be dated, but it works well for hosting discussions in a friendly environment. --173.49.9.242 (talk) 01:25, 29 December 2008 (UTC)

Is there any way to use my Firewire external drives to clone the old disk to the new disk? I was thinking of using some program like the GParted LiveCD to try and create a disk image from the old drive to the Firewire drive, then swap the new drive for the old one, then try to boot up in GParted LiveCD again and have it apply the image from the Firewire drive.

There is a difference between retaining browser history (the list of pages you've visited) and retaining the browser cache (the actual contents of those pages last time you visited them). I suspect the setting you've changed only applies to Internet Explorer's browsing history, and does not automatically mark websites to be available offline.

There are separate settings that tell IE to make pages available offline, and a special "offline browsing" mode that makes sure it uses these wherever available. I believe you have to turn this on for each site (I think creating a bookmark and saying "make available offline" is one method) rather than for all sites at once, but you may have to look in the online help as I don't know the details. - IMSoP (talk) 17:59, 29 December 2008 (UTC)

Borland C++

Hi,

What is the command that i can use to get a print out in Borland c++ compiler? —Preceding unsigned comment added by 202.124.160.216 (talk) 12:04, 29 December 2008 (UTC) "

We can't understand your question. What do you want to print out? --Sean 17:18, 29 December 2008 (UTC)

If the compiler has a Graphical User Interface (also known as a GUI or Integrated Development Environment or IDE), you can likely use the Print command from the File menu when the window which has what you want to print is open. If you are using a command-line compiler, just open the file you want to print with your favorite text editor, and print it from there. (You do not need a special program to open C or C++ source or header files - any text editor or word processor will do.) If you want to print the output of a command-line compiler to paper, the easiest way is to redirect the output to a file, and then print that text file using your favorite text editor. If those hint don't work for you, you'll need to be more specific, telling us 1) what, exactly, you are trying to print 2) the full name and version of the Borland C++ compiler you are using 3) which operating system you are running it on 4) anything you have tried that hasn't worked. -- 128.104.112.113 (talk) 19:33, 29 December 2008 (UTC)

Taskbar disappeared

I'm running Windows XP on my computer. I had a problem with a virus so I installed a program called Malwarebytes' Anti-Malware. I ran it and allowed it to clean whatever infections it showed on my computer. Trouble is that it might have ended up deleting some files that aren't malware. Now my Windows starts up without a Taskbar, and it also loads a message at startup saying a certain file (MKMKrnl.dll) is missing. The software in question also refuses to load (it gives its own message about some file being missing) but that's the least of my concerns right now. Can someone tell me how to get back my taskbar? --120.138.100.216 (talk) 15:12, 29 December 2008 (UTC)

Hmm... are you sure this Malwarebytes thing is reputable - it sounds deliberate to me... There'll be a way to get the taskbar back somewhere in the control panel, I'm sure... Try bressing the windows key on your keyboard - that should fix it if it's only temporary and accidental. If nothing else works, either re-install Windows or back-up the files you need onto a memory stick and restore your computer to its factory state. In future, try using programmes that have been recommended by friends or computing magazines - it saves a lot of trouble, trust me. Dendodge Talk^Contribs 15:23, 29 December 2008 (UTC)

Pressing the Windows key isn't working. The software, by the way, I got from download.com (it's on the most downloaded list and has gotten mostly good reviews). It did delete the files that I knew to be viruses, but I'm assuming it ended up giving some false positives. Anyway, I need a quick fix for this problem now before my dad gets home. Can you tell me how to get back the taskbar from the Control Panel? —Preceding unsigned comment added by 120.138.100.107 (talk) 15:29, 29 December 2008 (UTC)

First, Malwarebytes' Anti-Malware is a well regarded tool for dealing with malware. Aside from that, MKMKrnl.dll seems to be part of a virus, so it looks like the infection was not completely removed from your computer. As far as the taskbar, is there any chance it is collapsed? If you place your mouse pointer at the very bottom of the screen and it turns into a double-headed vertical arrow, just press the left mouse button and move up to resize the taskbar. Finally, is there any chance you can use the system restore function to get your computer back to a point prior to the virus problem? --LarryMac | Talk 15:37, 29 December 2008 (UTC)

Ah, yes, that is what had happened. My taskbar was locked however, which was why I couldn't resize it. Problem is it still doesn't show any of opened windows in it, even after minimising them. Also, does someone have any knowledge about a virus/trojan(?) going by a file called "amvo.exe". I seem to have gotten it from a USB disk-drive and now I can't double-click on any of my disk partitions directly from My Computer (the computer just restarts on its own when I do). It also stopped me from viewing any hidden and system files (though Malwarebytes seems to have solved that problem). --120.138.100.107 (talk) 15:46, 29 December 2008 (UTC)

A Google search for "amvo.exe" returns thousands of hits; this one might be useful for the links mentioned within the posts. --LarryMac | Talk 17:09, 29 December 2008 (UTC)

I know this isn't answering your question and probably isn't much help, but I absolutely hate dealing with viruses and trojans that have somehow permeated through the excellent defenses of my system. I find it easier (maybe not for you though!) to save all of my important documents and files onto a flash drive (I use my iPod, because it has a massive hard drive) and just re-install my OS. Clean start. --71.117.36.29 (talk) 20:46, 29 December 2008 (UTC)

The irony is that that is exactly what I had done in the first place. However, the virus in question spreads through flash drives itself, not something I knew before. So now, not only is my main computer infected (because I re-transfered all my backup through a flash drive) but also my secondary computer (on which I transferred all of my backup through - again - a flash drive)! Anyway, does anyone have a solution for my taskbar problems? It still isn't showing any of the opened programs on it, and its presence seems to be linked to whether the Language Bar is enabled or not.

P.S. Among other problems I've noticed (after my attempts at malware removal) - the audio isn't working, the copy-paste function isn't working and my computer starts up a lot more slowly. I can't even do a System Restore as it either fails to open (the first time I try it) or just shows a blank screen (the second time I try it). --120.138.100.51 (talk) 08:21, 30 December 2008 (UTC)

P.P.S. Btw, I've found a log file of all the infections removed by the said program. Would uploading here help if anyone would care to show me whether any necessary files were deleted in the process? --120.138.100.51 (talk) 08:28, 30 December 2008 (UTC)

Well, I have cleaned too many of these amvo.exe viri at my hostel. To start off, boot your pc to safe mode by pressing F8 just before the OS loads till start options appear. Open command prompt. Move to your system directory (mostly c:\windows\system32\). Type attrib -s -h -r amv*.* . Delete all those that appear. There might be more in the system. So, run msconfig.exe and view the startup tab. Uncheck all except the things you are most sure of. Then restart. 117.201.114.148 (talk) 09:16, 30 December 2008 (UTC)

A simple configuration for processing received emails

Right now I use Thunderbird on Ubuntu connecting to a number of external POP and IMAP servers (e.g. gmail). I'd like to enhance my current email system to add smarter processing and filtering of received emails (in particular I'd like to sort the email into several folders, based on several evolving criteria - it's something beyond what Thunderbird's rather basic filter setup can do). I'm a pretty competent Python programmer, so the actual filtering (and if necessary, retrieving the email) isn't difficult - but I don't see a simple way to deliver this email on to Thunderbird (or a similar program).

From looking at various howtos, it seems that I need quite a lot of stuff - fetchmail or getmail to get mail from remote POP/IMAP; an MDA like procmail to filter; a local POP3 server that takes procmail's output and re-presents it as POP (or IMAP); and only then can Thunderbird read the mail. This seems like an awful lot of stuff to set up, for one person reading three email accounts, delivering to one final client, with no need for remote access. I see why this paradigm would be necessary if I were supporting lots of recipients (i.e. hosting my domain's email servers myself), but for this simple task, this seems rather like overkill to me.

[Incidentally I can retrieve the email with getmail and deliver to an mbox inside my thunderbird's own storage, but Thunderbird doesn't see changes, and I guess isn't locking the files properly, as it doesn't anticipate anyone is doing anything nasty behind its back like this].

So my question is - is there a more straightforward way of configuring email fetch/filter/deliver-to-single-client than this? Thanks for your help. 87.114.154.43 (talk) 17:51, 29 December 2008 (UTC)

You could do everything up to the procmail step, but then use Movemail to get thunderbird to get the local spool. -- JSBillings 04:38, 30 December 2008 (UTC)

UVa online judge runtime error

I solved the first problem of the first volume in the UVa Online Judge in C++. When I compiled it with the compiler and options specified on their page, and ran it on the sample input, it gave the sample output. But when I submit the code, UVa tells me "Runtime error".

1. Is there some way to get the input for which my program failed, from the online judge?
2. Could someone look at my code version 3? It uses C++ and STL. I write readable code (Atleast I think so ;-) )

--Masatran (talk) 17:55, 29 December 2008 (UTC)

Are you sure that "runtime error" isn't being generated by the website? After all, there are no uva challenges running. You could determine that with this. -- Fullstop (talk) 19:52, 29 December 2008 (UTC)

@Fullstop: The "Runtime error" is not a website error since the webpage is fine. I am not participating in any contest; in UVa, submissions are allowed outside of contests.

@StuRat: I have added comments, etc. Could someone look at my code version 4?

--Masatran (talk) 09:04, 30 December 2008 (UTC)

I have looked at the code; and one problem I see is that vector_extend() resizes the vector, which in this case just pushes uninitialized integers to the end of the vector. In update(), supposing the vector cycle_length isn't long enough, you extend it to length (cycle.back() + 1); then in the next line, you access cycle_length[cycle.back()], which would be the last element that you pushed on; but it is some uninitialized garbage. This raises a BIG RED FLAG. You cannot possibly have a good reason for accessing an uninitialized value. --71.141.112.60 (talk) 10:43, 30 December 2008 (UTC)

I read somewhere that C-style realloc() of native arrays extends with garbage values, whereas resize() of STL containers is done with the default data-type value. I don't remember where. Could anyone provide any references on this? --Masatran (talk) 11:51, 30 December 2008 (UTC)

Yeah but primitive types like "unsigned" don't have a default value (i.e. its default constructor returns an uninitialized value). --71.141.148.143 (talk) 21:29, 30 December 2008 (UTC)

I searched but could not find any references on this...so I rewrote the code without making the assumption. Thus, my code version 5 --Masatran (talk) 12:33, 30 December 2008 (UTC)

Regarding the comments, they're a definite improvement. However, I'd like to see more explanation in the header of the program as to it's purpose. It currently says "Collatz conjecture" and lists a web site. However, the program needs to say what it does without reference to a web site. Does it try to prove the conjecture ? Disprove it ? List some numbers in the sequence ? StuRat (talk) 14:39, 30 December 2008 (UTC)

Album/Cover Art

I've been trying to re-tag my music library so that the metadata is correct. One of my main goals, however, is to get some cover art for every song I have. I have been using MusicBrainz's Picard tagger to do the job. It *seems* like it is successfully saving the cover art, and I think it is because when I click on a file that supposedly has album art, the art is displayed. The only reason I'm not positive that it is working is that I cannot for the life of me get the album/cover art to show in Songbird! I switched to Songbird a while ago because I absolutely hate iTunes, and Songbird works just great...besides the cover art problem. Because Songbird is not recognizing the cover art, it is not being synced into my iPod. I am embedding the art in the ID3 tag. Any suggestions? Thanks. --71.117.36.29 (talk) 20:43, 29 December 2008 (UTC)

Slow rotation

Last week I was having difficulty with the Internet like never before.

The details are in a section I started last week which no one answered in a short time, so it might not have gotten any responses.

What was different on this occasion was that when I clicked on "Diagnose" and "Repair" the computer went very slowly on both processes. And the circle that normally rotates quickly was rotating very slowly to the left of the name of the page I am going to.

I forget how to find out what version of Explorer I have, but here's the rest of my information, minus what identifies me:

Looking at your previous post, it sounds like you are using an external dialup modem, probably one that hooks up to your USB port. Is this correct? Who makes the modem? You might indeed want to get a new phone cable, especially if it's as flimsy as a twist-tie. Internally the copper wire may have broken inside the cable; and phone cables are cheap. Long phone cables should work fine (I used a 25-foot phone cable for net access for years) but as a general principle you ought to use the shortest cable that will reach the plug. Tempshill (talk) 16:12, 30 December 2008 (UTC)

No, it's not a dial-up modem. It was the power cord that was "flimsy as a twist-tie". Siemens makes the modem but it has the phone company's name on it and the phone company provides a manual which isn't worth much. The lights are only explained in the guide to setting up the computer.

The new cord connecting the modem to the phone jack, which has a splitter or filter, depending on who is describing it, is sturdier. The old one wasnt too substantial-looking.

By the way, the available disk space statistics are outdated. I just stored that information in case anyone asked, but the available disk space is pointless.

Can I use the 3 RCA cables for composite video (yellow) and audio (red & white) to connect the 3 component video connections? I don't own nor can afford a component video cable.

Calculating CPU usage (Solved)

There's an API function, GetSystemTimes, that tells you the total time spent by the CPU in three areas: kernel-mode, user-mode and idle time. I'm polling using this function every second and calculating the deltas (differences compared to the previous values) of the three times. How would I calculate the kernel-mode CPU usage (in %) and the user-mode CPU usage using these deltas? I've tried this article at CodeProject but I can't seem to get it working for calculating kernel-mode CPU usage and user-mode CPU usage as opposed to calculating the overall CPU usage. --wj32 ^t/c 23:07, 29 December 2008 (UTC)

you need a baseline to compute the percentage of. In other words, you need to know how much wall-clock time has elapsed in your clocking period. You get the latter from GetTickCount(). Then...

for...

FILETIME ftktime, ftutime; /* delta FILETIMEs. Rate=10,000,000 per/sec (100 nanosec resolution) */

DWORD elapsed_msecs; /* delta time from GetTickCount. Rate=1000 per/sec (1 millisec resolution) */

get...

ULONGLONG k_usecs = ((((ULONGLONG)(ftktime.dwHighDateTime))<<32) | ftktime.dwLowDateTime) / 10u;

ULONGLONG u_usecs = ((((ULONGLONG)(ftutime.dwHighDateTime))<<32) | ftutime.dwLowDateTime) / 10u;

DWORD ktime_perc = (DWORD)((k_usecs*10u) / (elapsed_msecs / 10u)); /* same as (k * 100) / elap */

DWORD utime_perc = (DWORD)((u_usecs*10u) / (elapsed_msecs / 10u));

That's off the top of my head, and intentionally unoptimized. ;) Note that none of these counters really have the rated resolutions. QueryPerformanceFrequency() gives you the real resolution. -- Fullstop (talk) 00:05, 30 December 2008 (UTC)

Thanks. Is there any way to do it just by using the three deltas? In that article there's a formula for doing that, but I'm not sure if it actually works. --wj32 ^t/c 01:31, 30 December 2008 (UTC)

elapsed_msecs, ftktime and ftutime are the three you need. elapsed_msecs is from GetTickCount, and the other two from GetSystemTimes (or GetProcessTimes). I might be able to say more if you tell me what you are intend to show (or what you are timing). -- Fullstop (talk) 01:50, 30 December 2008 (UTC)

Well... if you want to know - I have this project called Process Hacker (written in C#) at SourceForge. I'm making a clone of Process Explorer's System Information window. I have a CPU usage graph that should display the kernel-mode CPU usage (in green) and the user-mode CPU usage (in red).

I'm not actually using GetSystemTimes; I'm using NtQuerySystemInformation with SystemProcessorPerformanceInformation, but it's practically the same. It gives me a struct with IdleTime, KernelTime, UserTime, DpcTime, and InterruptTime. The weird thing is, KernelTime is always very large, almost as large as IdleTime, but UserTime is very small. This happens with both GetSystemTimes and NtQuerySystemInformation. So, I have two questions:

1. Shouldn't IdleTime be a lot bigger than KernelTime and UserTime, and why is UserTime so small compared to KernelTime?

2. How do I calculate the kernel CPU usage and the user CPU usage separately? You've already given me the answer, but is there a way of doing it without using GetTickCount?

--wj32 ^t/c 03:02, 30 December 2008 (UTC)

And, by "using the three deltas" I meant the idle time, kernel time, and user time. --wj32 ^t/c 04:11, 30 December 2008 (UTC)

I've found a solution! Thanks to this guy's tip:

 // Total all of the CPUs
 //      KernelTime needs to be fixed-up; it includes both idle &
 // true kernel time 
 //  Note that kernel time also includes DpcTime & InterruptTime, but
 // I like this.

Backdoor Again

1. Remember that "backdoor.tidserv" virus I was talking about above? Well, I got rid of it by deleting it manually (or, more accurately, "them" since there were multiple copies of it on the computer) - and by manually, I mean going to their directory, removing them, then deleting them from the Recycle Bin. Is it safe to do it this way? And the search engines are still acting strangely (they take me to random sites instead of the site I want). How can I fix this?

2. There is another virus on the computer called w32.tidserv. Everytime I scan for it, it says it was cleaned by deletion, but when I restart the computer, the damned virus is still there. Could this other virus be the cause of Google's and other search engines' strange behaviour? And can I delete this other one manually?

60.230.124.64 (talk) 23:13, 29 December 2008 (UTC)

TidServ is a rootkit. I already gave you instructions for removing it; get IceSword and you will be able to delete the rootkit. Also, deleting viruses is definitely safe. Just don't try to unload rootkit drivers while they're running. --wj32 ^t/c 04:22, 30 December 2008 (UTC)

Deleting files manually is not sufficient to remove a virus from your system. Most viruses embed parts of themselves in various system files where you won't be able to get at them. Use an antivirus / antimalware program. If your antivirus program claims it cleaned your system but it seems like the virus keeps coming back, then try a different antivirus program as well.

Help with Picture of the Year? :(

Hello, I'm sorry if this is inappropriate, but I was wondering if there is anyone able to help with Wikimedia Commons Picture of the Year 2008. The project started in October but since November nothing has happened. I asked over at Commons and someone said that the users in charge of the project had retired and weren't going to continue with it. I was looking forward to the event, and now I'm sad that it's been abandoned. Nevertheless, they also said that it would be possible to do it for January. Once again: I'm hoping somebody here could help out. I don't have anything to do with the planning of the POTY (nor do I have the skills for it), but I would help with anything I could.

that's because the whiter the image, the greater the current flowing through the wire, and so the stronger the electromagnetic field.

PAINT IN C++

hey all, Myself and my friend are currently working on our version of paint in c++ using turbo c++ graphics and dev c as the compiler. As of today we've already added many features to it, like changing colour, drawing lines,circles,rectangles,spray paint,writing text and the best one --> saving the drawn image and retrieving it at a later point in time.But these are the usual things which are already present in the microsoft paint and we were trying to think of atleast one feature that we can add to our paint which is like a unique feature if you know what i mean.

There's an ASCII format bitmap that I wish Paint would support (read and write), as it would allow me to use a program to create the bitmaps, then use Paint to display them or change them to a more compact format. Yes, you can create the usual binary bitmap formats from a program, but it's rather difficult to debug such a program, whereas human readable ASCII output is quite easy. Unfortunately, I forgot the name of the format, but it had RGB codes for each pixel, as two digit HEX codes. StuRat (talk) 16:55, 30 December 2008 (UTC)

But that's what imagination is about. As a quickie how about something based on drawing with a line of different colours like a bunch of crayons tied together? Or making the line wider the slower you draw? Or changing the last bit of the colours so you have a secret message or drawing you can reveal? Dmcq (talk) 18:35, 30 December 2008 (UTC)

RDP From windows to linux

I was just wondering if there was a way to use the RDP built in to windows to remote in to a Linux box. I am awear of several programs that work like RDP but those are not what i want. The reason is this: I switch computer often and most of the time i am unable to install new software on to these computers, and only very few of them am i able to stick a CD/Flash/any other type of memory device. In fact, most of the computers are very limited in what they allow me to do, but i have found a way to open RDP. So my queston is this: Is there some type of RDP server that i can run under Linux that would allow me to remote in to it? —Preceding unsigned comment added by E smith2000 (talk • contribs) 16:40, 30 December 2008 (UTC)

xrdp? --h2g2bob (talk) 18:52, 30 December 2008 (UTC)

Many of the standard VNC clients offer a Java-viewer, so you don't need to install software on the client-computer. You just open the browser to http://[addresstocomputer]:[someport] and a java-program starts and you can use that. Then you don't need to install any additional software, the computer only needs java (you can find the right port-number in the settings/documentation for the software). Look at Comparison of remote desktop software under the "Java Viewer" heading.

BTW, if you don't have a registered domain-name for your computer and don't want to be messing around with IP-numbers (they have an annoying tendency to change), you can use a free dynamic dns-service like No-IP. They work excellently, in my experience. Belisarius (talk) 18:59, 30 December 2008 (UTC)

xrdp is an RDP server for unixen. Also, several other remote desktop tools (including RealVNC, UltraVNC and x11vnc) also have Java clients, so all one needs at the client end is a Java-capable browser, and software installation is then unnecessary. -- Fullstop (talk) 19:00, 30 December 2008 (UTC)

Light on new modem not working

The full details of my question are in a post I made last week.

I went back to using the old modem, because whenever I would describe the lights on that modem, the tech support people would get concerned and claim I needed a new one. Therefore, they shipped me one.

The first light is the power light. It starts out red and turns green. It's not supposed to blink, but shortly after I started using that modem it started blinking for a while.

I never did see the leftmost light blink. It's supposed to blink in an irregular pattern but it never did anything (though the Internet worked fine for a while and I suspect an outside problem; see last week). If it doesn't blink on the old modem, the middle light starts blinking. The middle light is supposed to be solid, and when it is out or blinkiing, the Internet doesn't work. If a page is solw to load and the left light is off, the page will often come up just as the leftmost light blinks on.

A separate post from yesterday describes this modem.Vchimpanzee · talk · contributions · 17:14, 30 December 2008 (UTC)

It sounds to me like those are indicator lights, if the internet is working then i would not be concerned.

The problem is described in last week's post here.

I assume the Internet quit working because of something external and not a problem with the new modem.

I'm still using the old modem and it seems fine.Vchimpanzee · talk · contributions · 18:46, 30 December 2008 (UTC)

how to stop skype spam

I have a Skype account which I use infrequently, but sometimes have on standby while doing other things. Today I have received yet another porn spam chat message, of the genre: "Hi there!". I thought I'd better test my assumptions, so I responded blandly and immediately got, "I'm feeling lonely, do you have time for me?". A second bland response from me and then another reply so immediate that it shows it has all been automated long ago (and I thought the pornspam-meisters might use actual human beings to lure chatters into their lairs). This third line has the website, and a supposedly sexy temptation to visit it. Fat chance. So. My question is, what is Skype doing about this? And what should I do about this? I know the general rule is not to reply to spam, but in this one case I wanted to see what the procedure was. BrainyBabe (talk) 20:10, 30 December 2008 (UTC)

You could try closing Skype, only opening it when you need it. —Preceding unsigned comment added by E smith2000 (talk • contribs) 20:31, 30 December 2008 (UTC)

making a download link

Anybody know how to render an HTML link so that the end user's browser will go into its special download dialog, rather than rendering the linked-to page as usual? —Steve Summit (talk) 20:45, 30 December 2008 (UTC)

Tell said end-user to go to file > save to download the page. —Preceding unsigned comment added by E smith2000 (talk • contribs) 21:12, 30 December 2008 (UTC)

archives

I've got 10,000+ PDF files and I'd like a good way to store them, ideally compressed, in a way that enables moderately easy retrieval and adding of new files. So far I've got them in a 7zip archive but adding to a 4GB files takes a long time. Any easier options? Inb4 use the OS file system, opening 10,000+ files in one folder crashes the pc. Thanks for the help. —Preceding unsigned comment added by 82.43.88.87 (talk) 21:10, 30 December 2008 (UTC)
