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)[reply]

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)[reply]
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)[reply]
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)[reply]

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)[reply]

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)[reply]
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)[reply]
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)[reply]
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)[reply]
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)[reply]
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)[reply]

Texture file in games

220.225.242.194 (talk) 06:19, 20 December 2008 (UTC)harshagg hello, how to make a 3D texture file of extension .fbx,which software can be used for making it can adobe photoshop will be able to do this or I have to use another method for 3D game modelling if present[reply]

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)[reply]
Have you looked up fbx? It's more than just texture data. I don't know of any game engine that uses FBX files directly during runtime. --70.167.58.6 (talk) 16:53, 21 December 2008 (UTC)[reply]
It's not even texture data - it's motion-capture data - to do with animations. I can't imagine Photoshop could deal with it. Maya or 3DStudio probably can. SteveBaker (talk) 23:42, 21 December 2008 (UTC)[reply]

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[reply]

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

It's serious. It's a real site about speed runs. (speed runs = trying to beat the game in the fastest time possible, even if it means ignoring any secrets/powerups/etc.) flaminglawyerc 15:39, 20 December 2008 (UTC)[reply]

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)[reply]

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)[reply]
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)[reply]

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)[reply]

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)[reply]
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 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)[reply]
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)[reply]
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)

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:

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.

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".

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)[reply]

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)[reply]

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. flaminglawyerc 14:52, 21 December 2008 (UTC)[reply]
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)[reply]
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)[reply]
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)[reply]
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)[reply]

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)?

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.

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)[reply]

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

flaminglawyerc 02:49, 21 December 2008 (UTC)[reply]

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? flaminglawyerc 22:45, 20 December 2008 (UTC)[reply]

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)[reply]

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)[reply]

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)[reply]
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)[reply]
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)[reply]

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)[reply]

(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. flaminglawyerc 20:01, 21 December 2008 (UTC)[reply]
FWIW: I use Inkscape a LOT!SteveBaker (talk) 22:21, 21 December 2008 (UTC)[reply]
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)[reply]
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)[reply]
Thanks for the response. Xenon54 (Frohe Feiertage!) 22:33, 21 December 2008 (UTC)[reply]
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)[reply]

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 TalkContribs 21:46, 21 December 2008 (UTC)[reply]

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 TalkContribs 23:13, 21 December 2008 (UTC)[reply]
(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)[reply]
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)[reply]

Webcam/digital camera

I have a few questions: 1) Can webcams be bought for cheap, and how can I acquire a decent one for cheap? I'm tech savvy enough to know how to do things, so I don't need extra gadgets where I could accomplish something in software anyway. 2) Do digital cameras usually have webcams attached? And are the prices significantly higher? Thanks all. Magog the Ogre (talk) 04:31, 22 December 2008 (UTC)[reply]

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)[reply]
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.

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)[reply]

220.225.242.194 (talk) 06:43, 22 December 2008 (UTC)harshagg Why XNA is ignored while it is good it works on xbox 360 even and using 2D texture file is also easy in that while in opengl even creating a small car will take much of coding.MY friend is studying on opengl basics and I XNA and he could make a 3D car and I had made 2D track game(not long trak though) or it is a way that handling 3D in openGL is easy than XNA[reply]

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. Plus it doesn't work on Linux, Mac, iPhone, AndroidPhone, Nintendo DS, Wii, Playstation...OpenGL works on every platform that can do 3D graphics.

Getting rid of backdoor.tidserv

I have a virus on my computer called backdoor.tidserv. I need to know how to remove it. It makes some sites, such as Google, act strangely. I can't remove it with the anti-virus software because it shows up as "left alone". And I can't use System Restore because nothing happens when I click the "next" button on the third step. Is it safe to remove it manually by going to the directory it is in, right-clicking it, and choosing "delete"? If not, are there any free anti-virus programs that will remove this virus? Not those that require registration. Just the free ones. 60.230.124.64 (talk) 11:14, 22 December 2008 (UTC)[reply]

(ec) Yeah it annoys me too when someone suggests changing your whole OS and migrating your stuff just to fix some minor Windows problem.
this link tells you a bit about your virus. 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)[reply]
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)[reply]
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)[reply]
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)[reply]
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)[reply]
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)[reply]
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)[reply]

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)[reply]

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)[reply]
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)[reply]

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)[reply]

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)[reply]

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

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.

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)[reply]
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)[reply]
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)[reply]
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)[reply]
Actually, if your laptop uses MXM GPUs, it's normally easy to replace them - provided you get a MXM card fitting in the socket =).

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?

Try using google...http://www.googleguide.com/improving_pagerank.html or try looking at Search engine optimization and its links/use those words in a google search for more tips/ideas. 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)[reply]

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.

I agree with .46; by far the best option is to block a user. This automatically severs all connections you have to them (ie, friendship). From their perspective, you cease to exist.

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)[reply]

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)[reply]

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)[reply]


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)[reply]
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)[reply]

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)[reply]

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're not being very coherent. Most older games don't work correctly on modern pcs running XP or Vista.

(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)[reply]
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)[reply]

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? flaminglawyerc 05:20, 24 December 2008 (UTC)[reply]

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');

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.

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

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.

Overheating laptop while encoding DVD

My laptop suddenly shuts off when I burning encoding AVI files to be burned onto a DVD. Will changing my power saving mode to a less-energy consuming mode and hence, lowering my CPU clockspeed prevent my computer from heating up as much? Obviously it will take longer to encode.

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)[reply]

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)[reply]

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)[reply]

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)[reply]

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)[reply]

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)[reply]

Proprietary Programming Language

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

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)[reply]

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)[reply]

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)[reply]

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).

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