Smiley Face
When people post that they hang out at the smiley face, where is that? Thanks 72.84.30.159 02:30, 22 April 2007 (UTC)
- ":-)", ":)", ":D", "
", etc. just means someone is happy; or that the remark is not intended to offend. These faces are called emoticons. I've not heard of someone hanging out at :), but someone may be happy to be hanging out. --h2g2bob 03:04, 22 April 2007 (UTC)
Do you mean they said "I'm hanging out @:)" ? If so, perhaps the at sign represents hair on the smiley face. StuRat 07:27, 22 April 2007 (UTC)
CSS instead of tables: left align, center, and right-align, all on one line
I want to have one line of text with some text at the far left, some text at the center, some text at the far right. In the old days, I'd do this by making a table row with three columns and being done with it. But tables for layout are evil, I'm told, so I thought I'd try to do it with CSS-- thus far, I haven't stumbled upon the answer. What am I missing? --Wouldbewebmaster 03:43, 22 April 2007 (UTC)
Something like this? --h2g2bob 03:53, 22 April 2007 (UTC)
<div id="main" style="text-align: center"> <div style="float: left"> LEFT </div> <div style="float: right"> RIGHT </div> CENTER <!-- make sure it all stays inside the main div --> <div style="clear: both"></div> </div>
You could use display: table
, display: table-row
, display: table-cell
, etc. While using tables for layout is evil, I believe using CSS table layout isn't (the main problem with HTML tables is mixing content with formatting; tables are formatting, so they should be done in CSS). --cesarb 16:38, 22 April 2007 (UTC)
display: table
isn't IE6 friendly (and I wasn't sure it was IE7 friendly either)
You should use css classes to set up the columns, not inline stuff (unless you're on wikipedia... bleh)
I hacked this up real quick with a Real-time HTML editor. I didn't try it in IE but I can't think of anything here that wouldn't take care of it in IE. you may want to pad the middle column, but there may be problems of IE doubling the margin. I can't remember the fix. (positioniseverything.net is a good reference)
<style> .container{ _height: 1%; /*IE hack */ width:400px; } .container:after{ /* float container hack */ clear:both; content: "."; display: block; height: 0; clear: both; visibility: hidden; } .leftcolumn{ float:left; width:20%; text-align:right; } .middlecolumn{ float:left; width:40%; text-align:center; } .rightcolumn{ float:left; width:20%; text-align:left; } </style> <div class="container"> <div class="leftcolumn">This is a right aligned left colun</div> <div class="middlecolumn">This is a center aligned center column</div> <div class="rightcolumn">This is a left aligned right column</div> </div>

Image question
How do you scan an image from TV show or movie? I'd like to scan a few fair use screenshots for some film/TB articles. Incidentally, I looked into the rationales needed and policies. Aaron Bowen 07:12, 22 April 2007 (UTC)
- Most of those are taken from the computer via print screen. For Windows, you can take a screenshot from Windows Media Player, but first you need to change some settings, see: [1]. - Akamad 08:48, 22 April 2007 (UTC)
- Or you could just use VLC Media Player and use its built-in screencapture tool. Aetherfukz 11:19, 23 April 2007 (UTC)
Request for details on Error message "Skein 0.0.3 error code 2"
I have Broad band internet connection & using WinXP...while browsing continously for about 15 minutes, the connection is cut off showing the message "Skein 0.0.3 error code 2..contact the administrator etc". I need to log out and then log in again to resume browsing. I have contacted the administrator but they say it is a problem with the system. The hardware engineers who have checked the system have also not been able to identify the problem. What does this error pertain to? I have checked the internet for Skein 0.0.3...all I am getting is details of baseball scores(?). Please help. rimenon—The preceding unsigned comment was added by 202.164.146.103 (talk) 07:45, 22 April 2007 (UTC).
i think its a os.i also get this messege. it runs on my isp's computer
the logout i think happens because whatever software you are using for logging in(my isp has given me 24 online client") logs you out after a set time of inactivity . maybe you can set it using the "logging in" software or you could ask your admin to increase your inactivity timeout...
or if you log in using a web pageit is because your web browser does not have the ability to "keep-alive" a connection ... you can probably set it to keep alive ..

Optimal encoding of (not with) a Huffman tree
I have a scheme which uses (2 + m)n + 1 bits to store a Huffman tree (where n is the number of symbols, and m is the number of bits per unencoded symbol). Is there a more compact scheme? (I have the beginnings of a (1 + m)n + constant scheme, but I'm not sure if it's workable). --User:Taejo|대조 13:07, 22 April 2007 (UTC)
- If I am not mistaken, every binary tree with unencoded words at the nodes is a possible and distinct Huffman code. This means that you will need to store at least a binary tree (plus your codes). According to the binary tree article, this takes 2 bits per node. Every binary tree with n leaves has 2n - 1 nodes total, creating a total size of 4n - 2 bits for the tree. After this, you can simply store your codes in post-order traversal (size m*n bits, the very minimum, since you have to store the unencoded codes anyway). Assuming the unencoded words are stored in a fixed length representation, you'd need some constant amount of bits c to delimit the list of words and the tree representation. The total works out to mn + 4n - 2 + c , or n(m+4) - 2 + c. I may have made a mistake somewhere (I'm no expert on this stuff), but I don't think you can get any smaller than this. Every possible bitstring in this format is a distinct huffman tree and vice versa, any smaller and, you would't have enough room to assign a representation to every possible tree. Could you tell us your (first) scheme ? risk 17:27, 22 April 2007 (UTC)
- With pleasure. The trick is that not all binary trees are Huffman trees. Huffman tree nodes are either leaves or have two children. Which means you only need one bit per node: 0=leaf, 1=nonleaf. And you can eliminate the constant for the separator by simply storing the m-bit words immediately after the 1 bits for nonleaves. The (1 + m)n scheme (which I know realise is workable, and the constant is -1) relies on the two-queue construction algorithm. You store a bit for Q1 or Q2, and since leaves only come out of Q1, you can store the m-bit words immediately afterwards. Since (as far as I can see) the algorithm takes (n-1) iterations, you store (1 + m)n-1 --User:Taejo|대조 07:53, 23 April 2007 (UTC)
- Oops, that scheme needs 2 bits per iteration, since two items are taken each iteration. Since the codes are equally optimal if a tree is left-right mirrored, only one of (Q1,Q2) and (Q2,Q1) is needed. As a terminator we can just take an extra node from Q2, since as soon as it has less than 1 element, the algorithm is complete. So we can use n trits or n log23 bits to encode the tree shape plus mn to encode the values. Still not sure if this is optimal. --User:Taejo|대조 16:04, 23 April 2007 (UTC)
Computer Spec, difference between processors/etc
I'm in the middle of trying to find a suitable upgrade for my parent's PC. They have a Dell 8250 (http://support.dell.com/support/edocs/systems/dim8250/specs.htm#1084976) and we want to upgrade (ideally) RAM to 1gb, add a reasonably decent Nvidia graphics card, upgrade the processor and maybe add a second hard-drive. From looking at the spec i'm not sure what things I can add that are 'compatible' (the ram Is DRAM? Can't figure the max processor it can accept and it has AGP 4x/PCI so not sure which graphics card is best to upgrade to). Any help/points in the right direction welcomed. Sorry I know this isn't 'exactly' what reference desk is for. ny156uk 16:14, 22 April 2007 (UTC)
- Nyan? Not what the reference desk is for? I don't see the problem with this question. It's not homework and it's general help. Anyways, looking at the page you linked, you want to upgrade RAM to 1GB, but what does it have right now? It seems to take "PC800 or PC1066 RDRAM (non-ECC)". The PC800 looks to be about USD$200 for 512 megs. You can get up to a 3.06GHz Pentium 4 running with a 533MHz bus. The chances are, you can upgrade the harddrive with any ATA type because it mentions 2 3.5" bays. I say that because it might not have more molex power connectors for another device (or only has one IDE channel, which isn't too likely, but does happen on mass produced computers), but then you can split it, although be careful about the power supply being only 250 watts. As for video cards, even most new cards have AGP8X/4X versions. But like before, remember that you only have a 250 watt power supply, so a lot of the high end ones can't be used in your parents' computer without upgrading the power supply too. My advice? Buy a cheap refurbished computer or an older new one on ebay or something, because that will end up cheaper. --Wirbelwindヴィルヴェルヴィント (talk) 16:36, 22 April 2007 (UTC)
- Thanks for the response Wirbelwind. I found the RAM to be extremely costly for some reason, compared to DDR/DDR2 variants. I would like to end up with a computer something like...3ghz, 1gb RAM, 128mb Nvidia Graphics Card (or better!) at minimal price. Already have 120gb HD, DVD-ROM, CDR+W, Monitor, Keyboard/Mouse/Printer/Wireless Card/Network Card/Licensed Copy of Windows. I'm trying to get it for around £200 ($400). I have found the components required (processor/ram/card for about £100 but need to get a motherboard/box to host it all - that's where I am struggling). Thanks for the details, hadn't even considered 'power' as an issue. ny156uk 17:32, 22 April 2007 (UTC)
- Out of curiousity, why do your parents want to upgrade? Unless they're trying to run Vista, or they run intensive things like games, you shouldn't need to upgrade RAM or the graphics card- HDD I can understand though. If they run XP, and it's running slow, you might have better luck backing up their media and reinstalling windows. Windows has a bad habit of getting bogged down with a lot of unneeded stuff. -- Phoeba WrightOBJECTION! 02:16, 26 April 2007 (UTC)
Computer thinks its dual core
I've got a single processor Intel P4 650 3.4GHz machine. Lately, I've noticed that it seems to think it's dual core... whilst system properties correctly identifies the processor, device manager lists the computer as "ACPI Multiprocessor PC" and under processors, lists the P4 twice. Task manager shows the two different graphs for my "two different" CPUs. The net result of this seems to be that single threaded processor intensive tasks (such as mencoder) are only ever given 50% of the available processing power. Right-clicking and choosing to "uninstall" one of the processors doesn't seem to work, so I'm hoping for some alternative suggestions... Thanks in advance └ UkPaolo/talk┐ 16:44, 22 April 2007 (UTC)
- It shouldn't really affect it that much, but what you have is called hyperthreading, where it has a pseudo dual core. You disable it in BIOS to enable/disable hyperthreading. --Wirbelwindヴィルヴェルヴィント (talk) 16:49, 22 April 2007 (UTC)
- Though there is very little reason to disable it. SMT doesn't limit each thread to "50% of the available processing power". -- mattb 16:56, 22 April 2007 (UTC)

Ubuntu/Linux Software
I am buying a new laptop soon, and think that I'll get myself a non-Mac notebook and then set up some sort of Linux/Ubuntu/Kubuntu OS. I know most of these don't support quite the range of software as does a Mac and not nearly as much as a PC, but I've had trouble finding specifics. For instance, GIMP aside, can I buy and install Adobe Photoshop on a Ubuntu computer? Linux? What about Itunes? Can I get most non-game Windows-friendly programs to install on Ubuntu or Linux or whatnot? How about the regular Microsoft Office package? Do I have to buy a special type of MS Office? Will it not work at all? Are the alternatives really up to snuff, and will regular (ie mac or windows) using computers be able to open files I've made in, say Spreadsheet or OpenOffice? Will fairly obscure Windows-friendly programs such as Xilisoft, MacDrive, Daemontools, RosettaStone, and other work on any Linux/Unix-based OS's? And, final question, I sometimes go to download freeware and am given the option of whether to download it for Macs, Windows, or Linux. Could I not install this freeware on a Ubuntu computer? I know that's a lot of separate questions, but I think it all boils down to whether if I use Ubuntu or Linux I wont be able to use all the programs I've come to know and love. Thanks for any help, 70.108.191.59 19:53, 22 April 2007 (UTC)
- There are no versions of Adobe Photoshop and Microsoft Office that are natively supported by Ubuntu. However, using CrossOver or WINE, those programs will work.
- Don't know if iTunes is supported by CrossOver or Wine, but Kubuntu comes with Amarok which you can use to upload music to your iPod.
- OpenOffice will open spreadsheets and word documents from MS Office, but some of the more complicated formatting and such might be lost. But in general, for most documents/spreadsheets, this isn't a problem.
- You can definitely open OpenOffice docs in MS Office.
- For the more obscure software you described, there is usually a (K)Ubuntu alternative.
- Don't really know what you mean by that last question. If the freeware has an option to install in Linux, then you can install it in (K)Ubuntu. But there are easier ways to install software on (K)Ubuntu that browsing for it on the web: Package management system.
- Hope this all helps. - Akamad 20:36, 22 April 2007 (UTC)
- I expect someone will beat me to it (and I was right), but here goes. First, I should explain what the difference between Linux and Ubuntu is. In the early nineties, a guy named Linus Torvalds started work on an operating system. This was just the kernel of the operating system, which means it handles all the basics of various components of your computer talking to each other, starting the computer up and so on, but on its own doesn't make a computer usable yet. It's basically the software that's needed to start writing specific programs (like a window manager that draws windows on the screen, or an office application that uses the window manager). What's more, Torvalds made his software open source, so that anybody could look at, and use the source code behind his kernel. He named his kernel Linux. The Linux kernel was quickly combined with other open source software (mostly from the GNU project) to form an entire operating system, the set of software that is needed for a user to be able operate a computer. This operating system is known as Linux too, or as GNU/Linux. Since this GNU/Linux is basically a bag of different software, which you can install in many different ways, and which you can distribute freely, people started installing GNU/Linux in their own way, and then distributing it with things like friendly installation procedures and a set of preconfigured software packages. These are the different distributions of GNU/Linux, and Ubuntu is one of them. In short, Ubuntu is Linux, but Linux is not necessarily Ubuntu.
- As for the available software, the linux experience is slightly different than that of windows. The open source ideology has a very active community of programmers behind it, and most types computer programs have some open source variant. For instance, one open source office suite is OpenOffice (which can indeed open MS Office files without a problem in most cases). The great joy of distributions like Ubuntu is that they make use of the fact that open source software allows you to redistribute it. This means that you don't have to go to the OpenOffice site to download the program and install it yourself, because the ubuntu guys have done that for you already. They've taken the OpenOffice software, and adapted it slightly to make sure it runs smoothly on any Ubuntu system. All you need to do is tell a program within ubuntu (called synaptic, or simply "add/remove software") that you want openoffice, and it downloads and installs it for you. Pretty much all open source software written for linux can be installed this way.
- Not all software (even open source) is written for linux, and you can't install software written for one platform, on some other platform (with the notable exception of cross platform software, like Firefox, but even that has different versions for different operating systems). Photoshop has versions for Windows and for the Mac, but not for Linux. The same goes for MS Office. There is the possibility to install Wine, which allows you to run windows software in linux, but this doesn't work perfectly. For instance, this allows you to run photoshop 5.5, but not CS2. The wine project has a big database on what will work, and what won't. So no, you won't be able to use all the programs you've come to know and love (some, perhaps), but you might grow to know and love a lot of new ones. risk 20:45, 22 April 2007 (UTC)
Clock speed and FLOPS
I was about to delete a sentence of the FLOPS page , but, for fear of making an idiot (as I'm not too familar with hardware) of myself, I thought I'd ask here first.
According to that page, the CPU of a "common AMD A64 or Intel Pentium 4 general-purpose PC" (I'm guessing aroung 3Ghz), would have a FLOPS rating a ten. Which in turn leads to the conclusion that these processors perform over three calculations per clock cycle. This seems quite absurd to me, how is it possible for a CPU to perform three calculations in one cycle? —The preceding unsigned comment was added by 217.42.242.45 (talk) 20:04, 22 April 2007 (UTC).
- Ten GFLOPS, you mean. The answer lies with SIMD. The Cell microprocessor's vector units (SPUs in IBM-lingo) are designed to perform eight single-precision floating point operations per cycle. -- mattb 20:45, 22 April 2007 (UTC)
- Many of today's CPU cores execute single execution path instructions in parallel. Even 20+ years ago, instructions were executed in "parallel" so to speak as the execution time for each instruction was significantly overlapped for fetching the instruction, processing, storing results, etc. In another instance, (my memory may fail me here, so take this with a "huge" grain of salt, but) I've heard of instances where the first few instructions of all three "if","then","else" paths of an if/then/else block are executed and when the results if the "if" operation actually completes, the results of the correct "then","else" path are saved and used for further instruction processing. I can't remember what that's called. Or maybe that's just something I imagined. Root4(one) 01:43, 24 April 2007 (UTC)

Mp3 files that display very long running times
Hello, I'm sure many of you have seen mp3 files for songs that should be normal length but for some reason have very long running times, possibly due to somebody tampering with the files or something like that. Today I opened up an album (Black Mountain's self titled) in iTunes and the track lengths ranged from 20 minutes to almost an hour - in a playlist the running time for the 8 songs total was almost 5 hours. I assume that in most files with incorrect running times, the file plays and then there is silence for the duration of the song or something like that. However, with these files, they actually played for the entire running time. There was no silence - there actually was 5 hours worth of music. I then opened the files with Windows Media Player. The files were a few minutes longer than usual and still displayed the incorrect times, just not as excessively long as when opened with iTunes. Now upset, I opened the files with a sound editing program called Audacity, and it displayed the songs at their correct running time.
My question is - how is it possible that when I open the songs in iTunes, they magically play for 40 minutes? The beginning and ending of the song is the same no matter what program I play it with, and as I scan through the song with iTunes I can hear the same melody throughout the song. I'm extremely confused because it seems like when I play the file with iTunes, I somehow unlock an extremely lengthy, jammed out version of the song. However, when I open the file with Audacity, it shows the sound wave file at the length that it's supposed to be. Also, with iTunes, it says the bitrate of the song is 32 kb/s. With Windows Media Player, it says it is a 350 kb/s+ VBR file. What is going on!!?!? NIRVANA2764 00:17, 23 April 2007 (UTC)
- This only happens with variable bit rate files. The reason is because in a constant bit rate file, it takes the first bitrate it is encoded at and using the file size, it can figure out how long the song is with simple division. However, with variable bitrate, the first chunk might be encoded with a really small bitrate, such as 32kb/s, because it is mostly silence. Programs such as iTunes would see that 32kb/s, and the file size, and figure out the incorrect song length. However, programs which analyze the entire file will have the correct size. --Wirbelwindヴィルヴェルヴィント (talk) 04:02, 23 April 2007 (UTC)
Laptop Screen and Magnet
I have a Dell Inspiron, and I was playing around with a strong magnet near the screen, trying to see if it would distort it as it does CRT monitors. This didn't work, so I ran the magnet along the top edge of the keyboard, where it meets the plane of the screen. As I moved the magnet back and forth along this line, the screen dimmed as I passed over the middle. Finally, as the magnet passed over the middle again, the screen blacked out (though I could barely see it in a very dim form). I hibernated the computer and turned it back on, after which point the screen was completely restored. Does anybody know the mechanism for this effect? --Gujarat10 03:27, 23 April 2007 (UTC)
- Speculation here, but the ELP backlight used on many laptop screens involves an itsy bitsy high-frequency high-voltage power supply, which is often located about where you describe. It wouldn't surprise me too much if a strong external magnetic field could somehow collapse the magnetic field inside the HF HV PS's itsy bitsy exotic transformer. —Steve Summit (talk) 03:38, 23 April 2007 (UTC)
- Some laptops use magnets in order to determine when the screen is closed (as opposed to using a mechanical switch). If your laptop is set to only turn off the backlight when the screen is closed, rather than turning off the display as well, that could be it. Or not. -- Consumed Crustacean (talk) 05:34, 23 April 2007 (UTC)
- Nope - I have it set to activate standby when closed, which did not happen. --Gujarat10 06:54, 24 April 2007 (UTC)

- Huh? LCDs usually don't contain materials that exhibit strong magnetic properties. You can wave a stack of strong rare earth magnets over any TFT LCD you like and you're unlikely to observe any visual response. What's more, the OP described an effect that obviously affected the backlight (which most calculators do not have), not the LCD itself. -- mattb 01:38, 24 April 2007 (UTC)
- Right, the original experiment was an experiment with the LCD display itself, which I was commenting on (sorry for being vague). THEN continuing his experiment he found something which brought about the unexpected results, although rather interesting, the knowledge could have come at a hefty price. I was just trying to say, if one feels like monkeying around with some item, he or she should make sure that the item can handle the abuse or that the item is easily replaceable. There's nothing wrong with experimenting in itself, but it must be reasonable. Experimenting with magnets on a relatively new laptop, well, you draw the conclusions.

Video Problem
I downloaded some videos that are apparently in .avi format. I've tried playing them on what I feel to be everything -- Realplayer, Quicktime, DivX, WMP, VLC, InfraView, -- and they just wont play. They are certainly video files. They are about 350 mb each, and I have read online reports from others that they're viewing the videos just fine. What could be going wrong? What should I do? To give you better details, most media players say something to the effect of "Error: ____ media player cannot read this file. Make sure it is a valid media file type." VLC, on the other hand, opens it, but rather than playing the movie, for about five seconds the progression bar (the thing that moves slowly when listening to a song or watching a movie) moves as if something is being played, but nothing can be seen or heard and the clock of the VLC player shows no length to the file being played. Bizarre. Help? 70.108.191.59 04:21, 23 April 2007 (UTC)
- If even VLC doesn't want to play it, the file is probably corrupt, or it's some weird format that is very rare. Try checking the CRC? --Wirbelwindヴィルヴェルヴィント (talk) 05:11, 23 April 2007 (UTC)
Thanks, but what do you mean by "try checking the CRC"?
- Assuming you downloaded the file, thus the other people can play it, then you can get a program to check its crc (such as quicksfv, see sfv), and see if it matches everyone else's copy. Or if you got it through a torrent, check with the torrent file. --Wirbelwindヴィルヴェルヴィント (talk) 05:40, 23 April 2007 (UTC)
- Check what video codec the file uses and whether you have the codec. I use AVIcodec for that check. Then google to see if there is a newer version of the codec. Weregerbil 08:08, 23 April 2007 (UTC)
- Or open the video up in VLC and go to View > Messages - usually if you Google the error messages you will be able to deduce the problem. x42bn6 Talk 14:31, 23 April 2007 (UTC)
- Try Media Player Classic and all the assosiated codecs which come with it. That plays *everything* for me :) JoshHolloway 18:08, 23 April 2007 (UTC)

- It's possible that the file is actually corrupt. This has happened to me in the past! Try downloading another copy of the file, or from another torrent tracker. JoshHolloway 22:31, 23 April 2007 (UTC)
- You could try removing the file extension and then using VLC or MPC if that does not work try using one of those mass video file converters...Look on this website http://www.erightsoft.com/SUPER.html this has a converter for almost anything i've ever tried to use and it's free so just look into it.Have you tried opening it in Video Editing programs? Adobe Premiere, Sony Vegas, Windows Movie Maker? What about the option to look for the proper codec with the new Windows Media Player? 200.12.231.42 23:48, 23 April 2007 (UTC) Ag for MemTech
- It's also possible the file is a fake. Are you sure people are talking about the file you have not some other file with the same name? Nil Einne 00:38, 24 April 2007 (UTC)

If you build a system based on the intel CD2 e6600 processor, a gigabyte ds3p motherboard and a 8800GTS you'll have a great system and it should come in your budget. All you need extra is some ram, a hard disk, a power supply (550W will be good for that)and a case, doesn't matter what you get but I would recommend not to get the very cheapest, get the "next to the cheapest" and you'll be fine.

Anyone know about Adobe Photoshop Elements?
I use Adobe Photoshop Elements a lot. Just recently, it started having a problem. Whenever I try to open certain types of vector files in Elements, the program shuts down. This happens with .pdf] files and .ai files. However, .eps files open fine. And it doesn't even list any of my.svg files in the drop-down, so I don't know what happens for those. (Also, if I happen to have a pdf or ai saved to the clipboard, even if it just happens to be the last thing I saved there, Elements won't open at all — so I go to any website, right-click on a .gif or .jpg, and then with that now in the clipboard Elements opens fine.) Elements only just started doing this. Until a few days ago, all of these formats opened just fine. What could have happened? — Michael J 00:18, 24 April 2007 (UTC)

Smart Keystroke Recorder
I hope you can help me, I have no idea where else to ask about this.
I just became aware of a program called Smart Keystroke Recorder on my computer. Although I never noticed it before, it says it was created on my computer in January. After Googling it seems that this is a professional program used by people to record Internet activity and not a spyware program like I thought. Since I live alone, I know nobody went on my computer and installed it manually.
Can somebody remotely install a program like this on my computer? Is this someone trying to hack me or someone maliciously targetting me? Is there a way of finding out where the information is going to? (I already uninstalled it, but there seem to be files left over)
Please let me know, I'm very very concerned. —The preceding unsigned comment was added by 24.118.254.142 (talk) 04:22, 24 April 2007 (UTC).
a) There are ways to install GUI programs remotely. b) It takes about 30 seconds of physical access to a computer to backdoor it.
You could attempt forensics (on a separate machine) and watch all inbound and outbound traffic with a packet analyzer (on a separate machine). After you are done analyzing, you need to fdisk and format that machine. Any executable on that machine is potentially backdoored, and needs to be reinstalled from clean media.172.131.17.62 04:45, 24 April 2007 (UTC)
DDR error simple explanation
Hi Wikipedia,
I was advised to send this question to you for a better result although i did get an answer from your miscellaneous desk. I just wanna know in a simple term what does DDR SDRAM at DIMM (s):1 error means. I sometimes got this error when I open my PC then I will restart again and click del tab and set up then when I go back to boot , everything went fine. Then again next day when I open the same error occurs-DDR SDRAM at DIMM (s):1Does this mean that I need to replace my memory? I cannot contact any manufacturer because my computer was set up by a Computer graduate and he cannot be found now. I spent over a thousand bucks for this computer. Please help. Thank you so much...!

- The error is a general error, and a specific meaning can not really be given from what you have mentioned, it simply means some type of error is occurring. "Stick" is a term used for a Module of RAM/Memory. The RAM article has a picture showing this at the top. "Slot" is where the Module is placed inside your computer. Your best bet to have this fixed is to have someone test and maybe replace the Module for you (a friend with computer knowledge, or a local computer store). gorffy 10:01, 24 April 2007 (UTC)

PrefixSpan Algorithm
(I've posted this also in the mathematics reference desk... not sure if it's more appropriate here)
Hello, I have a question regarding the PrefixSpan algorithm. This algorithm can be consulted in the following paper "Mining Sequential Patterns by Pattern-Growth: The PrefixSpan Approach" by Jian Pei, Jiawei Han, Behzad Mortazavi-Asl, Helen Pinto.
My problem is with this sentence: "To avoid checking every possible combination of a potential candidate sequence, one can first fix the order of items within each element. Since items within an element of a sequence can be listed in any order, without loss of generality, one can assume that they are always listed alphabetically."
Furthermore in the definition of a prefix say that among other things a sequence A is only a prefix of B if each item of the last set of items of A is alphabetically before every missing item of the corresponding set of items in B. Then they go on how to define a suffix of a sequence given a prefix an then that a projection of a sequence database with regards to A is a the set of suffixes given A as prefix.
I don't understand how the assumption of alphabetical ordering does not result in loss of generality. For example given a database like:
a(abc)bd
a(ac)bdef
A frequent pattern with minimum support count 2 would be a(ac)bd (i.e. article a, followed by article a and c together then article b then article d. If we follow the lexicographical ordering within itemsets assumption we will fail to find this itemset since a(ac) is not a prefix of both sequences ? Or am I misreading something in the article.
Kind regards and thanks for your time.

- A GIF file (of the flavor GIF89A) can contain multiple images with associated control information, meaning an animation can be contained in one file. A JPEG file can only contain a single image.

Right now my Mpbs is 54.0 and I was told to change my Mpbs to either 1 or 2 or 1-2 or something but I dont know how to change the settings can someone PLEASE explain to me how? The router is built-in the laptop not wireless
- Why would you need to change? Am I missing something? Splintercellguy 02:55, 25 April 2007 (UTC)
Well this is what was said at nintendowifi.com:
"The Nintendo DS has a transmission rate of 1 to 2 mbps (megabits per second). Most routers transmit at a much higher rate, but are able to adjust for devices that transmit at a slower rate. Your router may have this as a setting that might need to be adjusted.
Look through your router settings for anything that indicates transmission rates. If the router is set to accept high transmission rates only, this will need to be changed to accept all, or for some routers, changed to specifically accept the 1 to 2 mbps range."
I just want to know exactly where do I go to adjust the settings to a suitable transmission rate.Where do I find the router settings? The router is BUILT IN the laptop by the way. Do I have to go to the Control Panel or something?Thanks
- I don't think "the router is built-in the laptop". You would probably access the web configuration page for the router. I'm pretty sure this isn't applicable to you. Splintercellguy 04:25, 25 April 2007 (UTC)
Word 2004 sporadic crashes
I use Word 2004 at work, and for whatever reason, it will crash on me every so often. The only pattern there seems to be to it is that it usually crashes when I try to save or print, but it's random as to when it crashes. Sometimes it'll work happily for days at a time without crashing, other times it'll crash multiple times in one day.
I'm using an iMac G5 1.6Ghz with 512MiB of RAM running Mac OS X Tiger (either 10.4.8 or 10.4.9, I think). Can anyone explain why Word keeps crashing on me? --Lumina83 02:16, 25 April 2007 (UTC)
- Well, it's made by Microsoft, isn't it? More seriously, there are a lot of patches for the Microsoft Office, whether on a PC or a Mac. Are you patched up-to-date? (It's relatively easy and painless to have Office automagically update itself from time-to-time.)
- I think so; it's version 11.3, if that's what you mean. --Lumina83 12:30, 25 April 2007 (UTC)
- Microsoft current offers a patch to bring Office/Mac to 11.3.4 here. I'm not sure what version of Word that creates, but it sounds like you might benefit from updating. (You'll probably need earlier updates as well, but they're linked from that page.)
- I just checked: Word, allegedly patched up to date on my PowerBook, says it's 11.3, build 070131.
- That's exactly what mine says. Version 11.3, build 070131. --Lumina83 10:05, 27 April 2007 (UTC)
- Then I can't be of any further help to you; sorry! If you can pin down one or two actions that seem to provoke the crashes, you could always try Microsoft's support groups. You might also want to see if the problem is known in the PC versions of Word; one of the interesting things that occurred when Microsoft started building Mac/Word and PC/Word from the same(ish) code base is that they started sharing bugs in common. I used to have a (big) document that had a lot of the same problems whether edited on a Mac or a PC.
What computer should I buy?
My current computer is frustratingly slow, and I want to get another one eventually. I'm looking to use either Ubuntu or Mac OS X, as Windows Vista doesn't appeal all that much to me.
I mainly use the computer for web browsing & email, playing music, viewing pictures & videos, and playing the odd freeware/old DOS game. Also, I mainly prefer to use freeware and/or open source software.
I don't want to buy a computer that's overkill for my needs, but I also don't want a computer that'll be slow and laggy like my current one is. Any recommendations? --Lumina83 02:16, 25 April 2007 (UTC)
- Probably a Sempron and 512MiB ram would do, plus a motherboard with builtin 6100/6150 graphics or the ATI ones (duno about drivers though), and that should do the job well. --antilivedT | C | G 03:15, 25 April 2007 (UTC)
- Would a Sempron be fast enough? The Sempron article states it's only comparable to a Celeron D, and my current system is already a 2.66GHz Celeron D--although it only has 192MiB of RAM after the integrated video takes its 64MiB share. --Lumina83 04:29, 25 April 2007 (UTC)
- I have a Sepmron 3100+ (got it when it first came out, 2 and a half year ago) overclocked to 2.3Ghz, NF3 motherboard, 1.5gigs of ram and a 6600GT. And I still can play any game out there with at least medium quality on at least 1024×768, run Beryl (beware of the black window bug though) on Ubuntu and I'm very satisfied with it. As long as you don't do 3D rendering or transcoding video all the time you should be fine. --antilivedT | C | G 04:37, 25 April 2007 (UTC)
- If you're going to use ubuntu and don't want to go through driver hell, don't use an ATI graphics card. ST47Talk 04:10, 25 April 2007 (UTC)
I recommend making your own computer from parts (newegg.com is the cheapest and most reliable source i've found), as it is much cheaper, and allows you to have much more control. From the sounds of it, you don't need much, so you should be able to go fairly cheap. The laginess from your current computer sounds like it's to do with multitasking, so go with 512MB of RAM and a multicore processor, such as the Core2Duo. a 1.8GHz C2D is probably suitable for your needs. You probably don't even need a graphics card unless you want to mess around with Compiz and Beryl (the former is very much worth it, the latter i've heard good things about), so go with something low end, like a GeForce 5200. As the person above me said, never buy an ATI gpu for Ubuntu, or linux in general. Their driver support WILL make you cry. If you need help, check the contacts info on my user page, i'll be happy to chat about it with yah -- Phoeba WrightOBJECTION! 06:37, 25 April 2007 (UTC)
- Unfortunately, Newegg's no good for me, as I live in Australia and they don't ship internationally. I don't think I'd have enough know-how to build my own computer, anyway.
- I was thinking of just installing Xubuntu on my existing machine, but the two things stopping me are the ATI graphics chip and the wireless card (Acer IPN2220 or something like that, it's only supported in Ubuntu via ndiswrapper and doesn't work out-of-the-box. --Lumina83 08:25, 25 April 2007 (UTC)
- Other than a slight increase in RAM, I do not see why a 2.66GHz Celeron D wouldn't be plenty sufficient for the uses you listed. Maybe you need to format and reinstall the operating system. Often times Windows will get bogged down by numerous background processes and such and run slow. So rather than spending money on buying a new computer, try formatting the hard drive and reinstalling Windows (along with all the other programs you use on a daily basis).--152.23.204.76 13:46, 25 April 2007 (UTC)

- I'd suggest a few pretty basic/obvious things that I always forget about when this stuff happens ;). First off, clear cookies and cache in your Web Browser. Next, try clearing XP's local DNS Cache by going to Start > Run. Type "cmd" into the box and click okay. At the command line that open type "ipconfig /flushdns" (without the quotes). You may want to give your computer a scan for malware which may be interfering with this (not common but I've seen it happen). gorffy 18:26, 25 April 2007 (UTC)

A program to "undirectorize"
Is there some kind of program (for Windows, Im not asking for some exotic bash scripts) that can move all files from subfolders to its folder. Example:
Books Book001 Book001.opf Book001.prc Book001.nfo Book002 Book002.opf Book002.prc Book002.nfo
I would like to move all .opf, .prc and .nfo files to the "Books" directory. Actually, I need only .prc files but anything better than manually visiting each folder to grab its .prc file would be nice. Of course, Books directory usually has a lot of subdirectories.
Shinhan 11:12, 25 April 2007 (UTC)
- I don't expect there to be a ready-made program that does precisely this – that is what bash scripts are for. However, you could do a search (with the built-in Windows tool) for the files you want so as to get them on a single list, then just drag and drop them where you want. —Bromskloss 11:45, 25 April 2007 (UTC)
- D'oh. I could've just searched for *.prc inside the "Books" directory. Thanks for reminding me :) Shinhan 13:17, 25 April 2007 (UTC)
- Yes... and what would happen if your search comes up with several files of the same name. That's all cool when they're in separate folders, but putting them in the same folder would cause problems. I hope the search solution worked for you though. Rfwoolf 13:18, 27 April 2007 (UTC)

You typically want to set it to 100% zoom level. You definitely don't want less than 100%, but there are cases where you would want more. If your screen is at it's resolution limit (say it's set to 1600x1200 pixels), you might want to go with 200% zoom, especially if your pic is small. You could also go with 300%, 400%, etc., but always stick with a multiple of 100%. If you have a program which can do pixel interpolation, then go with the highest zoom level you can get.

Program to print a conversation-view summary of an email folder
The work I do sometimes involves the forensic analysis of large collections of third-party emails (back-and-forth exchanges). In order to gain an overview of the conversations (which sometimes reach positively Byzantine degrees of complexity) I'd like to be able to print a summary of a mail folder, with threads indented. While most current mail clients will display a folder in threaded-view, I don't know of any that will print the folder window (the top-right pane in Firefox, for example). There seems to be no way in Firefox, Evolution, or Outlook 2003 for this to be printed (bar some naff printscreenery).
I've considered doing something like trying to wedge the email archive into something like GNU Mailman (producing nice output like [11]) but that seems like overkill (and will be rather too hard for the nontechnical users I'm trying to help).
Does anyone know of a program or email-client-extension that can do this. XP or Linux would be fine, and while mbox, maildir, live IMAP, and .pst archives are all desirable, I'll take what I can get. Thanks. -- Finlay McWalter | Talk 12:39, 26 April 2007 (UTC)

Fancier setups interpose an amplifier/signal splitter box so your computer can drive both a CRT monitor and the projector, but you don't need this if you're using your laptop; just put the laptop into "mirror" mode where the laptop display shows the same thing as the projector.
- More-modern computers have different video ports such as a DVI port. Most of these can still output "VGA" video through a very inexpensive adapter. Some modern projectors may also accept DVI directly.
- Sound is equally easy; get a cable that has an 1/8" stereo miniplug on one end and the appropriate connectors for your sound system (often, RCA connectors) at the other end. The miniplug plugs into your PC's "headphone" jack.
- If the sound system and projector are far away, you still may need an amplifier near your PC; such gadgets are available from computer shoppes. Sometimes, the sound system will experience a buzzing due to the existence of a ground loop. If you have a laptop and your presentation isn't too long, try unplugging your laptop from its power supply (so it runs just on its battery). Otherwise, you'll need some audio isolation transformers.
- As Atlant said, any projector system made in the last 10 years or so should have both a VGA in port and a stereo "headphone" jack. Usually you don't need an adapter for the sound at all; for video it depends on your laptop (many have VGA ports, some have mini-VGA or DVI ports which require $20 adapters, see your computer retailer for those). --24.147.86.187 22:38, 26 April 2007 (UTC)
- An alternative way to do the sound is through the S/PDIF port if you have one. This has better quality and only uses RCA cords, and is worth doing if you have a compatible amplifier. Hope this helps

- Recently I've had the join to interface a newish laptop (no VGA, only DVI port) and projector (also no VGA only DVI port) using VGA extension cord. Which meant using two DVI/VGA converters. Since those are pretty small be sure not to forget one when you need it... To connect computer with sound system you will need still more converters, like Atlant said, maybe even RCA to XLR converterters. (The wireless microphone I'm working with requires 3 converters to plug into the mixer) Shinhan 12:23, 27 April 2007 (UTC)

changing keyboard layout
I downloaded a program called Keyboard Remapper to change four keys in Windows. Every program I've used so far reads these the way I want them to, except some Flash games which now refuse to read those keys as either the changed or original values. Is there a way to fix this? 172.144.83.53 21:36, 26 April 2007 (UTC)
- Sounds like the flash games are reading the actual keys and not their values (i.e. looking for "the first letter key" rather than "the q key", which can be remapped). I doubt there is anything you can do except complain to the game designer that that's a poor way to do things, one which doesn't appreciate the user's intentions. --24.147.86.187 22:40, 26 April 2007 (UTC)

Sticky Excel/Access 2000 problem regarding importing DB with URLs hidden with anchor text
If anyone can either answer my question or direct me to where to get more info, I'd be most appreciative.
I have a large flat file database in Excel2000 which includes a bunch (2000 or so) hyperlinks with anchor text. I'd like to upload the whole thing into Access2000 but it turns the hyperlinks into plain text (showing the anchor text, not the web addresses), and changing the field type from text to hyperlink isn't available in the import.
So... I'd like to figure out a way to do this. The way that seems most obvious is to remove the anchor text in the excel file so that I can upload as html, but I'm open to other solutions. So, how do I remove the anchor text to reveal the URLs? Or how do I do this another way? Thanks in advance. Anchoress 03:20, 27 April 2007 (UTC)
- My untested guess is that it would be easiest to write a little VBScript that will go through and separate the links into two columns, one of links and the other of anchor text. Now unfortunately I don't know anything about using hyperlinks in VBScript and imagine that will take a little hunting around to get right — potentially in the Hyperlinks collection but I don't really know. I see a lot on a quick Google search on adding hyperlinks but imagine there must also be ways of accessing their properties as well. Then it's just a matter of iterating through the recordset and putting the links into a new column or something along those lines, which will take a minute or two but should work fine. --24.147.86.187 03:45, 27 April 2007 (UTC)
- If your input file is a comma-separated values file like this:
thing1,thing2,<a href="http://some/url">some anchor text</a>,thing3
- then a bit of Perl like this:
perl -pe 's#<a href="([^"]+)">([^<]+)</a>#$1,$2#' < input.csv > output.csv
- will turn your rows into this:
thing1,thing2,http://some/url,some anchor text,thing3
- --TotoBaggins 04:02, 27 April 2007 (UTC)
- Thanks for the answers you guys, but it's not as simple as that. The data was copied from web pages as anchor-texted hyperlinks, so there's not two sets of data to separate in the .xls file; the actual typed contents of the cells is the anchor text. It's going to have to be something to do with a dynamic paste or something, I have no idea. I've fiddled with a bunch of paste specials, and looked through the installed formulas, but I don't know. Anchoress 05:15, 27 April 2007 (UTC)
- Saving (or exporting) the spreadsheet as a .csv file will presumably turn the hyperlinks into their natural <a href="..."> state, and you could then do the text manipulation above. I don't have Excel, so I'm somewhat out of my element, but it can't be so daft as to just discard the URLs when exporting. One hopes. --TotoBaggins 05:23, 27 April 2007 (UTC)
- No, it didn't, unfortunately. It just exported the anchor text. I was able to paste the plain URL as a hyperlink to another cell after copying, with a particular paste function, but it only worked with one cell, not a range. Anchoress 05:36, 27 April 2007 (UTC)

Have you tried the "Replace all" function - but I understand that it won't help you with the part of the URL code that you want to replace that changes with each one - instead you'd need something more dynamic to do that - where it could say "Delete everything after the '>'". Check the link above from TotoBaggins which seems to take care of what you're looking for. I'd be able to help you otherwise by writing up some code, but I battle a bit with VB - so worst case come back here and I'll write it for you. Rfwoolf 13:10, 27 April 2007 (UTC)

- Here's another solution: I think that Access allows a hyperlink data type, no? It might only be in later versions than 2000.... --140.247.240.159 16:45, 27 April 2007 (UTC)
- Yes, it does, but as I said in my question, it isn't available as a field type in this import, and by the time the data is imported, it's already been delinked. I'm going to try a lazy solution suggested on the Access Developers yahoogroup, and if that doesn't work I'm going to try the VB solutions proposed here. Anchoress 22:18, 27 April 2007 (UTC)
- XML alternative: One approach may be to save the file in "XML Spreadsheet format" (if it is supported by your version of Excel). What that will do for you is convert the "hyperlink objects" into readily-modified text that you can then extract with an XML parser or script or whatever. If I remember correctly, Access also has an XML format that it understands for import, so you might not even have to mess with the XML before importing to Access. (See e.g., Microsoft_Office_Excel#File_formats apparently, XML output is not supported in excel 2000? :( .dr.ef.tymac 04:23, 28 April 2007 (UTC)
- Yeah, that sounds good, I'm going to try it. Anchoress 09:10, 28 April 2007 (UTC)
Request for clarification:
If you want me to come up with the VB code, please clearly explain what you want. Is this correct:
The cells in Excel contain hyperlinks and the raw code for each one reads
<a href="http://www.example1.com">Example1</a>
and you want to extract it to say
www.example1.com
Is that correct?
Rfwoolf 08:15, 28 April 2007 (UTC)
- You certainly don't need to do anything for me, but no, that's not at all what it's like. As I've said a couple of times, it's an embedded object, so the actual contents of the cells is just the anchor text. There's no <a href> stuff at all. So if for instance the text is copied and pasted somewhere, or if the file is saved as .txt or .csv, or if it's imported into access, the URL field shows just the plain text representation of the anchor text.

- Just to let you know that some "hosts" do not allow such content on their servers. Typically you might be able to get away with it for a short period of time, but ultimately if it's not allowed then your account may be suspended - so just a tip, you might want to read over the terms and conditions of any given host -- just in case you didn't know.
- Also, when you register a Domain name, you provide a variety of information about who owns the domain, their billing address, their contact details, the webmaster name, the server person's name, etc. but I've seen quite a few hosts offering to "hide" this information from the general public - but charging you to do so - that might be an option. Of course all you need to do is look at a way to obfuscate this information when you register the domain - that's not to say you must do anything illegal, but you might look into whether you can get your host to use their details and not yours - although that would mean that they own the domain name and not you. My advice is to look for some "Adult hosts" or just for hosts - and talk to them about your request and see what they can do for you.

Installing a Windows XP MBR
I have two hard drives: we'll call them Drive 1 and Drive 2. My installation of Windows is on Drive 2. For historical reasons, the boot drive is Drive 1. Presumably (bootloaders confuse me, so I might have something wrong) when the BIOS starts it looks for a bootloader in the MBR of Drive 1, which then boots the NTLDR on Drive 2, which in turn boots Windows.
Setting the BIOS to boot Drive 1 works fine. Setting it to boot Drive 2 leads to an error message, presumably because there is no Windows bootloader in the MBR of Drive 2, so naturally nothing can boot.
Now, I want to format Drive 1 so I can install Linux on it (yes, yes, hold the cheering), but presumably formatting Drive 1 would remove the MBR and stop me being able to run Windows. I know GRUB should be able to boot Windows, but in case of any problems I'd rather that I could just boot Windows off Drive 2: but I have no idea how to install a Windows bootloader on the Drive 2 MBR.
Any ideas? Sum0 16:35, 27 April 2007 (UTC)
- If you have your WinXP CD this can be done from the recovery console. Boot from the CD and enter the console at the appropriate time. Then, use the fixboot and fixmbr commands as shown: fixboot and fixmbr gorffy 16:55, 27 April 2007 (UTC)
- I have tried FIXBOOT, which seemed to work fine, but I'm not sure that that was the problem. I ran FIXMBR too: it said I had a "non-standard or invalid master boot record". After some consideration, I went ahead anyway, and it said it completed successfully - but it didn't solve anything. Which I don't understand, unless possibly it wrote to the Drive 1 MBR by default (I didn't specify a drive). I'll try specifying Drive 2. Sum0 17:03, 27 April 2007 (UTC)

- I believe Hiren's Boot CD has MBR tools that can fix your problem. Splintercellguy 22:03, 27 April 2007 (UTC)
- I think all XP MBRs are created equal, so you can use dd to copy the MBR from the working drive to the other one:
- boot into knoppix or another liveCD (personally I found Ubuntu's install/liveCD to be very satisfactory)
- dd if=/dev/hda of=/dev/hdb bs=512 count=1
- that's assuming /dev/hda is drive1 and /dev/hdb is drive2 : you should change these as appropriate - if you get the above wrong you'll copy drive2's bad MBR over drive1's good one, and thus be doublescrewed - so test mount them both to make superultramegasure. -- Finlay McWalter | Talk 22:12, 27 April 2007 (UTC)
- OK, I'll consider that. That just copies the boot code, right? It won't screw around with the other MBR stuff (I'm pretty hazy, but I believe the stuff there is Important)? Also, one drive is FAT32 and the other is NTFS. That won't matter, will it? Hiren's Boot CD looks worth a try too. Sum0 22:23, 27 April 2007 (UTC)
- No tool can get you fired faster than dd, so you're wise to be cautious. That 512 will copy all of the MBR, which Master boot record notes does include a partition table - copying 446 bytes instead should copy just the code (but it's not clear that this will be sufficient for you, as we don't really seem to know what the condition of your drive2 MBR is. If you're nervous (wisely) you can save drive2's MBR to a file on a USB flash drive with dd if=/dev/hdb of=/media/usbdisk/drive2_old_mbr bs=512 count=1, so you can always restore it from there (by exchanging if and of) later if things go bad. -- Finlay McWalter | Talk 22:34, 27 April 2007 (UTC)
compilers and interpreters.
hi ... i have doubt abt the difference between compilers and interpreters and assemblers..pls help me thanx in advance chakradhar 17:43, 27 April 2007 (UTC).
- A compiler compiles source code into machine code that the computer can run directly. An interpreter interprets code as it's run, changing it into 'directions' for the computer as it goes along. That's the best I can explain it, someone else can probably do better. The articles on both topics cover differences between the two and advantages to each. -- Consumed Crustacean (talk) 17:52, 27 April 2007 (UTC)
- Though a lot of "interpreters" these days use a form of compilation to increase performance. As was stated, read the articles. -- mattb 17:56, 27 April 2007 (UTC)
- A compiler turns a portable high-level language like this:
int square_it(int x) { int squared = x * x; return squared; }
- into machine-specific assembly language like this:

- An assembler then turns that output into a series of bits that you can feed directly to a CPU with no further changes. It's not readable by (normal) humans, but looks something like this for the file above:

- Traditional interpreters are programs that just read the high-level language and follow its instructions as they go. A modern example is bash. Many modern languages (like Perl and Java) do something more like the compiler example above, except in the last step they interpret the binary file and do what *it* says, rather than feeding it to a CPU. --TotoBaggins 18:54, 27 April 2007 (UTC)
- It's incumbent on me (as a fatally flawed nitpicker) to observe that assemblers rarely if ever produce something "you can feed directly to a CPU with no further changes", and indeed the binary example you show is such a case. An assembler generates a binary object file (in this case ELF - the first four bytes, in Intel byte order, are [DEL]ELF). That has to be sent to the linker to have any external references resolved. And even then the file is still ELF (or whatever), and that's still not executable. Finally the code has to be loaded (or "located"), where fixups are resolved, .bss sections wiped, and .data sections initialised from .text. In the case of a "real OS" this is done by the ELF loader, or its equivalent, when you exec the code, but in the case of embedded systems this is done explicitly by the locator, the last element of the tool chain. As a long-time systems developer it vexes me some (and this isn't a dig at anyone posting here, honest) that CS departments spend ages in compiler class on lexical analysis and syntax handling, wave their hands a bit at code generation, and make no mention at all of the latter half of the compilation chain. -- Finlay McWalter | Talk 00:50, 28 April 2007 (UTC)
- Yes, good followup! I thought about mentioning loading, but decided it would get too far afield for the OP, so stuck with a lie to children. --TotoBaggins 04:10, 28 April 2007 (UTC)
- See also Cross-platform, and Write once, compile anywhere for additional insights on some of the points mentioned above. dr.ef.tymac 00:49, 28 April 2007 (UTC)
Installing Software on XP
Is it possible to install, say a web browser, onto a single user account on a Win XP PC with multiple users, so that only that one user will be able to use it?
The reason I am asking is because certain software become defaults and open themselves for certain file extensions. Is it possible to make it so that it will only 'exist' on one account?
Thanks in advance. Skumbag - 酢薫バッグ 18:43, 27 April 2007 (UTC)

Protecting illustrations from Acrobat OCR
When I perform OCR in Adobe Acrobat Professional and choose Formatted Text & Graphics for output, part of an illustration will sometimes be recognized as text or white space. How can I mark off an illustration and tell Acrobat not to OCR it when it's doing the rest of the page? NeonMerlin 00:22, 28 April 2007 (UTC)
Oh crap
I just received this message on my browser (FF): http://img413.imageshack.us/img413/241/ohshatoe2.jpg
Which is almost exactly the same as this: Image:Winantivirus.png
Ironically about a week ago I had read the WinFixer article here. Before pressing any of the buttons I shut off my internet and then pressed the Cancel button, although I am still very worried. I did what the WinFixer article had directed me to, but am I safe? Please re-assure, I don't want to suddenly find my computer going haywire. --TV-VCR watch 04:25, 28 April 2007 (UTC)
- Err, you're not in any danger. That article is pretty poor. It seems that WinFixer either utilizes some exploit in IE to install itself, or just tricks the user into downloading it. So long as you didn't download and execute it, you're not at risk. I'm not aware of any major code execution exploit in the latest Firefox release, and certainly not any that are in the wild... -- Consumed Crustacean (talk) 04:30, 28 April 2007 (UTC)
- Things like that generally don't cause your PC to go haywire, just become slower and pop up windows like that. Before you do anything, make sure it was from malware on your PC instead of a popup. Since you're on FF, chances of it being a popup aren't good, especially if you use AdBlock and filtersets. If you don't, I recommend you install those right away, as they will help not only keep malware off your PC, but also make your internet experience much more enjoyable (I actually forgot that banner ads existed on the internet until I got my Wii, and even then it took me like five minutes before I realized what the hell they were doing there). After that, (assuming you're using Windows XP or Vista, chances of this happening on Linux or OSX are extremely low), download and install Spybot Search and Destroy (http://www.safer-networking.org/en/index.html) and Hijack This (http://www.spywareinfo.com/~merijn/programs.php). Run Spybot S&D. It will probably bring up a lot of stuff, check it over before you delete it, as they are occasionally false positives. If it says you cannot remove the program, or it comes back, then you get into the dirty stuff.
- !!WARNING!! Before you do any of this, you should back up your media, and make sure you have a windows install disk, as you CAN mess up your PC with this. Be prepared to have to format and start over. First, you need to turn off system restore, as this WILL keep the virus around. Go into your system restore settings, and choose to disable it. !!WARNING!! This WILL destroy all your previous system restore checkpoints, so if you mess up after this point, you're reinstalling. Turn your PC off and boot into Safe Mode. In safe mode, run Spybot S&D. After it's done scanning and cleaning, run Hijack This. CAREFULLY delete entries. If you don't know what you're doing, post the Hijack This log to people that do (most forums will request this, I believe HT has a forum you can use). These entries are mostly GOOD things, or even necessary. Delete the malware entries (or whatever ones the forums tell you to delete), close and restart. Should work after that. Again though, if you don't know what you're doing, be sure to request help, and be sure to ALWAYS archive your data before messing with your registry or anything delicate. -- Phoeba WrightOBJECTION! 04:44, 28 April 2007 (UTC)
- Err. If that message was due to spyware already on your computer: worry (and get rid of it). If that message was just from a website trying to trick you into downloading WinFixer, as it looks like, don't worry. At all. Just ignore it, never visit the crap filled site again, and live on. -- Consumed Crustacean (talk) 04:46, 28 April 2007 (UTC)
- Yeah, sorry, don't mean to make you panic. Like I said (Probably should've put more emphasis on it), you're probably OK. I still recommend downloading Spybot-S&D and HT though, they are very useful. Also, download Adaware. Run lavasoft's Adaware and Spybot-S&D every few days and your PC will be among the cleanest a Windows computer can be and still be connected to the internet. -- Phoeba WrightOBJECTION! 04:55, 28 April 2007 (UTC)
- That's only a confirm box - very easy to do in JavaScript. There is no risk - any web page can make an alert box pop up like this. See this w3schools page for an example of this in action (together with the code which goes on the web page). I use the NoScript extension, which blocks JavaScript. --h2g2bob 05:19, 28 April 2007 (UTC)
Question about this computer font style? older computers used it
What is it called when you make large letters out of capitalized letters? a capital "A" is made by using the capital A to make the shape of an 'A'
there must be some program out there to generate these automatically??
if this doesnt remove whitespace, the A, B would look like:
A BBBB A A B B AAAAAA BBBBB A A B B A A BBBBB
whats this called? thanks —The preceding unsigned comment was added by Bradz1234 (talk • contribs) 04:46, 28 April 2007 (UTC).

Why can two anti-spyware programs happily co-exist on the same computer...
...but two anti-virus programs, if installed together, will lead to endless conflict? --Kaypoh 06:43, 28 April 2007 (UTC)
likely because, one, anti-spyware programs typically are ran once, and then turned off, whereas antivirus are running constantly, and because anti-viruses try to modify things that set the other one off. Why would you want more than one anti-virus though? If you need that level of security, you're probably better off using a more secure OS, such as a Live CD -- Phoeba WrightOBJECTION! 06:53, 28 April 2007 (UTC)
DDR2 backwards compatibility?
I know DDR2 isn't backwards compatible with DDR, but if I plug a 1066 DIMM into an 800 slot, will I have any problems other than the RAM being slower than it could be? I somehow missed this, even though I must've checked over the parts for this PC a dozen times =/ Should be an easy question, thanks -- Phoeba WrightOBJECTION! 06:57, 28 April 2007 (UTC)
- It would work perfectly fine. --antilivedT | C | G 07:57, 28 April 2007 (UTC)

Percent encoding of forward slash in Firefox gives 404 error in Wikipedia
I have a Firefox keyword search bookmark set up so that when I type 'wpgo pagename', it will bring me to the corresponding Wikipedia page, e.g. 'wpgo User:Harryboyles' brings me to my userpage. However this doesn't work for subpages. Firefox converts the forward slash to %2F
, which then causes Wikipedia to give a 404 error. I filed a Bugzilla request (bug 9204) but Brion said that it was a low level 'feature' in Apache and couldn't be fixed from them. Is there a way to make Firefox pass the forward slash as normal? Harryboyles 08:26, 28 April 2007 (UTC)
- I have a similar feature in Opera and I've just tried it and it works fine with /s. This indicates that it is Firefox's doing rather than an Apache feature. I wouldn't know how to get Firefox to do what you want though, sorry, though you could code a workaround if you so required (and had the knowledge). JoshHolloway 08:45, 28 April 2007 (UTC)
Hiding my ip address
Hi, im looking for the safest and most reliable way to hide my real ip address. How would i go around doing this? just software? or more than that? THNX for any help.
