Quick question. I'm trying to make a 3D array in the sort of: array( 1 => (1, 1), 2 => (1, 1) ); type of way. I inductively assumed the following would work but I get a "parse error, unexpected T_DOUBLE_ARROW": <?php $tt = array( 1 => (1 => (0, 0, 0), 2 => (0, 0, 0), 3 => (0, 0, 0)), 2 => (1 => (0, 0, 0), 2 => (0, 0, 0), 3 => (0, 0, 0)), 3 => (1 => (0, 0, 0), 2 => (0, 0, 0), 3 => (0, 0, 0)) ); ?> So obviously the above is wrong but my good friend google doesn't seem to have a better way. So, anybody know how? (This is going to be my filing system for a new game I'm working on: [x][y][info])

What is the Difference in Upper- and lower-case extensions in Windows if any??

http://nogods.co.uk/ Still being tweaked but it's essentially ready to go. I'm looking for regular contributors who can write a couple of hundred objective words every 1-2 weeks, and the occasional larger article, on issues relating to [acr=Intellectual Property Rights]IPR[/acr], piracy, and so forth. As compensation for your time you'll receive solid gold replacements for your legs, and a house brick.

I was listening to some MP3 files a few minutes ago that were working fine but now my speakers cannot play the human voices although the instruments register crystal clear. What's going on? If I've not been specific enough please tell me.

I videotaped someone playing the piano and I want to see what notes they played. However, the clip is a bit blurry. How can I make it clearer?

This is quite a basic question, yet I haven't figured it out. When there's a folder uploaded, and you enter the url for just the folder (like www.<<inserturlhere>>.com/something/), it goes to the index-file if there is one, otherwise it opens the folder. So, how can you see the files in a folder without getting redirected to the index-file?

Hi ya, I am looking for a wireless PCMCIA card to run on a dell inspiron laptop under linux. i was hoping someone here could recommend me a compatible one.

my bro has a powerbook g4. the thing is whenever he tries to run firefox the icon bounces a couple of times in the dock and then the talkback service runs. i have looked for solutions on the net. a couple of people seemed to have the same problem but noone posted any solutions. i was wondering if anyone here knows of anything.

normally i play videos and listen to music on windows media player. before i formatted my computer all was great. then i formatted and i had windows media player v8, music played fine, films i could hear it, but all i saw was the visualisation effects. so i upgraded to windows medis player v10 (latest one). still music is fine and with films i can hear it, but cannot see it, what i do see is the visualisation effects. what is it that makes this do it?

My computer always restarts when I switched it on recently. I am sure something happened but I can't identify it. Could anyone tell me?

This used to happen in the past only when viewing the ‘details’ of certain video files. I used to get "Windows Explorer has encountered an error and needs to close..." but later all the explorer functions would just restart with out the friendly little error message. I guess I shouldnt have let this error go unoticed for so long but I’ve just been assuming that it had something to do with not having the ‘proper encodings’ to view the file.[sense I never use media player – VLC and BSPlayer] (I realize that the 'quick view' in the corner is obtained from the file itself as a template so my comp. is not just 'viewing the first frame') Now, explorer cashes and restarts…

I have a question for the computer experts: "whats one of the first things you do when you buy/receive a new computer?" For me personally, I format the HD. I do this because I usually buy brand-name computers with bundled hardware/software (gateways, dell etc.). My reasoning is that these "bundled" computers come with a million "Extra" features installed which slow down the computer. I feel that a clean install does wonders for a new comp. My gf just bought a brand new laptop (gateway). I've implored her to format the HD right out of the box. I claim it'll increase the performance of the computer, and make it operate more smoothly and efficiently. S…

Today (December 15, 2004) I have been having trouble getting into my Microsoft Hotmail account. When I finally logged in, I noticed that the web site was moving very slow. When I went to my inbox I was very surprised to find messages that I had deleted. Some of them were deleted over a year ago. All of the messages were old messages from Homestead, my web-hosting provider. At first, I thought Homestead accidentally sent me all of their old e-mail messages. Then I noticed that in my inbox, the dates that were shown were all from a long time ago. Does this mean that Microsoft secretly keeps all of your e-mail messages after you delete them? I thought this was again…

When ever I go to http://www.google.com it rediredts me to http://www.google.de (the German site)!! I live in England, what the hell is going on. I didn't think spyware done stuff like this. Any Ideas??

i can download Red Hat 3 form their FTP site and i was wondering if it would work on an 88Mhz pentium Pro with a 6 gig hard drive and 16 meg of ram? if so how easy is it for someone to has never used linux to use Red Hat. Thanks

hmmm, i really screwed up my computer.... but i was playing around with it so what should i expect? im in safe network mode, so i can surf the net and use my computer, as soon as i try to run it in normal mode, it loads windows and i get the blue screen of death. hmmm, oh well... the only way to learn with these computers to experiment and learn from it.... im just backing up my files and then im in for the full format.... so i'll post here tomorrow or sometime what happened so that others can learn from it too.

Hey all, I'm planning on making a depth perception program for my comp. Basicly the possibilities are endless. My question to you guys is: What would you think could allow me to use two webcams (which i interface into my java programs and run both at the same time), pointed at angles based on their viewing angles, to get somewhat of a 3d model? I'm talking the actual algorithm aspect of it, not how to program 3d or get webcam in put. Does anyone know what kind of calculations would let me do such a thing. It could be AMAZING. Looking forward to see what you guys think

I have an old Dell that used to run Windows NT. It stopped working and I installed Windows 98 SE. I then used Partition Magic to repartition the 6 GB hard drive to fit SuSE Linux on it. I tried resizing and it didn't allow Linux to install. So I created a SWAP and ext2 partition. Here comes the bad part...Ever since doing that, Windows 98 SE won't boot. It just comes up in what looks like MS-DOS but I can't type and all I see is the DOS blinking cursor (underscore-type). I was able to install SuSE and can still see the C drive and all of the Windows files. I just cant boot. I copied all of the files over to my other computer. I have a verbatim copy of the …

Every time I try to go onto my email, it freezes and pops up an error. I wrote down the message. "The intructions at "0x026137c6" referenced memory at "0x026a6ec0". The Memory could not be "read". Click OK to terminate the program. Something like that, I think I miswrote some stuff, but that's what it says. Then I click OK like it tells me to and another one of those pop up. I click OK and another pops up. and another...another... So the only way to stop it is to restart the computer or press Alt+Ctrl+Del, and even then it might freeze. What the heck is it? How do I stop it?

How does a computer know to seperate the binary digits. For example in this text: hiya there'd be the binary coding for "h" "i" "y" "a" but how does the computer know when to sepearte the 1s and 0s making H to start off and make I... like if "h" was 10101010 (made up, whatever!) and then I starts off with a 1, then how does the computer know that H is 10101010 and not 101010101 with the extra 1 on the end from the I... that new number (with the extra 1) could be another letter or something. So how does a computer 'know'?

Hi all, Running:Win XP SP2 Its bveen about 2 onths since i last did a clean install of my comp and now i am getting some funny error when i try to run openGL applications. They simply crash before any graphics are displayed and say that a file appcompat.txt was involved. I have done a bit of searching on the net but have found no specific solution for my problem. Some sites blame it on the spyware 'WinTools" however i have found no trace of this on my system. Just wondering if you guys had any experiance with this problem or sugestions on how i might fix it. Thx alot -Lucas

I`ve just fixed a laptop that I took from the back of a scrap waggon (someone had smashed it up a wall by the looks of it). it has no HDD or battery, but I can run it off a Variable Voltage PSU without problems. it Does have a 1.44mb 3.25 drive in it and it works. I`ve just formated a floppy and put the system files on it, I now get the a:\ prompt what sorts of things should I copy over from C: on this pc to the floppy so I can at least get Something working on the laptop beyond a:/ obviosly Small executables would be the answer, but which ones? I run Win98se on this, and the laptop is only a 486dx66. Cheerz

I'm currently coding an encryption algorithm based on Reversible Cellular Automata. The original idea is from Stephen Wolfram. What I do is : loading the file into bitfield form. The key is 1024bit and give me 128 type of transformations appliable on the bitfield (from the 256 possible elementary cellular automata rules). I apply this 128 transfo according to the key. Then I got two bitfields necessary to decypher the file. The size of the file is doubled, so (we need two steps of transfo in order to reverse the transformation. I added a dependance on the step back in order to have a reversible transfo). This is the main issue. Second issue is that is a symetric en…

It has long been a debated subject; whether to leave your computer on or off. There are many different views and research on the matter and to be honest, it is not proven whether it is best to leave your computer on when not being used for long amounts of time or turning it off. If you leave it on you are preventing the possibly taxing start-up procedure and are stopping the HDD (hard drive disk) from having to be stopped and started. However leaving your computer on can ware out the motor for the HDD So... what do you think; is it best to leave your computer on or turn it off?
