Strange XP Problem

I have this problem with XP that it seems to crash after 20 minutes or so of video chat, on both Live Messenger and QQ. The network would die off and pinging give "Destination host unreachable", then launching new applications would give an error of "not enough quota", or sometimes even "xxxx.exe is not a valid W32 programme". Disabling and then enabling my ethernet connection doesn't help, nor does the "repair connection" button. The only way to fix this is to restart (logging off and then back on doesn't work), but it will come back in another 20 minutes or so.

I have reinstalled Windoze but came to the same problem, and the problem only occurs while doing video chat, as XP is perfectly stable for hours of TF2 or others. My Ubuntu is as stable as ever so I doubt it is a hardware problem, and as reinstalling didn't help I am thinking it's a driver error. But before I go on reinstalling all the drivers I want to see if there are any other leads that I could follow to solve this problem other than hours and hours of driver trial-and-error. --antilived^{T | C | G} 10:48, 8 March 2008 (UTC)

It sounds like it's an issue with your video drivers. I wish I could help you more: perhaps you could try to find the drivers somewhere on the net (reinstalling Windows, BTW, was the right move IMO, even if it didn't work). The Evil Spartan (talk) 18:18, 8 March 2008 (UTC)

We have a similar problem, except just IM (W/Windows Live Cam X3000) crashes whenever I'm on too long. It's really annoying, but the only thing I could suggest would be to have your calls in 15 minute segments, close out, then redial. Andrew Kanode (talk) 20:13, 8 March 2008 (UTC)

PartitionMagic alternative for Vista

Does anyone know a program for resizing, moving and creating partitions without data loss for Windows Vista? PartitionMagic has compatibility problems, apparently. --Taraborn (talk) 13:26, 8 March 2008 (UTC)

Gparted? A brief googling doesn't turn up any strong complaints of incompatibility. --98.217.18.109 (talk) 14:52, 8 March 2008 (UTC)

Our article PartitionMagic says that... no idea whether it's wrong or not. Thanks to both. --Taraborn (talk) 16:39, 8 March 2008 (UTC)

Police Simulator

My brother is looking for a computer game in which the player is a police officer (preferably in the US), fighting criminality. He would like the game to be a Vista compatible modern 3D sandbox styled car game. Is there any such game? --Andreas Rejbrand (talk) 14:47, 8 March 2008 (UTC)

Modern 3D sandbox? How about GTA:SA in vigilante mode? --antilived^{T | C | G} 20:57, 8 March 2008 (UTC)

"Taxicab missions got old fast; if I wanted Crazy Taxi, I'd dust off my dreamcast" ... the SA minigames are borrrinnggg, especially Vigilante mode. He should try out SWAT 4. :D\=< (talk) 19:41, 9 March 2008 (UTC)

The closest I can think of is The Getaway, where (for part of the game) you are a police officer fighting crime, but it's set in London, and is only on the PS2 (and backwards compatible PS3s. The best "police" type game is SWAT4, although this deals only with on foot SWAT operations, and isn't really sandbox. The game focuses on the LA SWAT team, and you play through a variety of scenarios that are sort of realistic, and therefor quite challenging. By the way most modern games are Vista compatible. TheGreatZorko (talk) 15:03, 12 March 2008 (UTC)

The game you want is CRACKDOWN for XBOX360 and Windows, Its not at all realistic but its hell fun :)

VB6 Question

I'm going to feel like a total idiot posting this, but... I've got to learn Visual Basic 6 in one week , and I have to know a couple of things. Could someone tell me how to work out the problem V = A * (1 + R)^Y when V is the end value, A is the original amount, R is the annual interest rate, and Y is the number of years of gained interest; and the user inputs A, R, and Y. I have the form written in the editor, but I don't know how to get the values or make it calculate with the click of a button. Thanks A WHOLE LOT!!! Andrew Kanode (talk) —Preceding comment was added at 17:32, 8 March 2008 (UTC)

Add a few text controls on your form. Give them names like "txtOriginalAmount" and "txtAnnualInterestRate" and etc. Then add a button. Give it a name like "btnCalculate". Double click on the button and you should enter into the code editor and you want to edit/create the function btnCalculate_Click (there should be a little drop-down menu where you find this). Dimension your variables (Dim A as Single, etc.), then assign them the values from the text controls (A = Val(txtOriginalAmount.Text). Then do your calculaton (V = A * (1 + R)^Y) and then display the final value somehow (e.g. Msgbox V). Does that help? There's more to getting it right (what if they forget to fill in a value? what if they put invalid information in?) but that's the basic process. --98.217.18.109 (talk) 17:54, 8 March 2008 (UTC)

Best Program for Web Pages

Now that Frontpage is discontinued, what is the best software to create web pages with? —Preceding unsigned comment added by 67.126.131.115 (talk) 17:46, 8 March 2008 (UTC)

I use Mozilla Thunderbird. (Do you get it? That's an email client) In reality I use kompozer, which I ironically found using Wikipedia earlier in the year (maybe last). We have some pages on them, look at the WYSIWYG article, and follow links. Andrew Kanode (talk) 17:54, 8 March 2008 (UTC)

Even better: List of HTML editors Andrew Kanode (talk) 17:55, 8 March 2008 (UTC)

If you want to stay with Microsoft, see Microsoft Expression Web (the successor to FrontPage). Xenon⁵⁴ 17:59, 8 March 2008 (UTC)

Note that "best" is a matter of opinion. In my opinion, if it is a WYSIWYG editor, it is garbage. Anything more than a text editor is a waste of time. Your opinion will surely vary. So, instead of asking for the "best", you should ask for specifically what you want your software to do. -- kainaw™ 19:42, 8 March 2008 (UTC)

Myep. I prefer Notepad2, but any text editor is good as long as you type the actual code and don't use WYSIWYG ("Design" mode). --grawity ^{talk / PGP} 13:39, 9 March 2008 (UTC)

I of course code by hand but I understand that it's very hard for a lot of people to learn how to join the very skills of graphic design and good coding. They're two very different worlds. Computer people tend to think "good coding" should be valued above all else, but of course the real world doesn't work that way — your end goal is not always to impress computer people, but people who just want something that "looks good." So there's some place for a WYSIWYG editor in the world, I think, though I don't use them. --98.217.18.109 (talk) 20:03, 9 March 2008 (UTC)

Personally, I code websites by hand, but I find that the code-view in Dreamweaver is helpful. It offers syntax highlighting and auto-completion which just speeds up the process of coding a site. Acceptable (talk) 17:02, 9 March 2008 (UTC)

Syntax highlighting is helpful but total overkill for writing something as simple as a web page. Just use notepad/notepad2/vi/mousepad :D\=< (talk) 19:49, 9 March 2008 (UTC)

Eh, it's pretty useful when you make typos (is there shame in that, now?) and you can't figure out which errant tag has gone crazy. I use TextWrangler which is wonderfully bare bones (so to speak) but has nice and subtle syntax highlighting. And recommending vi to someone who wants advice as to which WYSIWYG editor they should use is pretty silly. (I've never understood the modern fetish with ages-old programs like vi and emacs, personally. I guess it must have some sort of retro appeal, the equivalent of insisting on using eight-track rather than CDs much less MP3s.)--98.217.18.109 (talk) 20:03, 9 March 2008 (UTC)

Personally I've never understood the backward fetish with bloated programs like emacs :D\=< (talk) 15:53, 10 March 2008 (UTC)

If you are looking for a WYSWYG editor, try Nvu. Even discontinued, it is still one of the best free editors for Windows. Personally I just use Vim the text editor, but that is not for everyone. -- ReyBrujo (talk) 20:07, 9 March 2008 (UTC)

"export" in OS X Terminal

I'm using OS X 10.4.11 (Tiger). I'm trying to install ImageMagick based on the instructions on this page.

My problem seems to be that the "export" command seems to only work for the session of the Terminal that I am running. When I close it down and open up Terminal again, it has forgotten everything. E.g., if I run export MAGICK_HOME="~/ImageMagick-6.3.9/" and then run echo $MAGICK_HOME, it'll tell me the right path. But if I close Terminal and open it again, when I run echo $MAGICK_HOME then it gives me nothing.

What am I doing wrong? I hate bash. --98.217.18.109 (talk) 19:12, 8 March 2008 (UTC)

This is true in all shells. You need to add the command to your bash configuration file. Doing a

echo 'export MAGICK_HOME="~/ImageMagick-6.3.9/"' >> ~/.profile

should do the trick. --Sean —Preceding unsigned comment added by 69.134.115.242 (talk) 23:16, 8 March 2008 (UTC)

OK, thanks. Wish the ImageMagick instructions had said that and not made me go through all of those hoops for nothing first. Will give it a shot. Thanks. --98.217.18.109 (talk) 04:55, 9 March 2008 (UTC)

No Dial Tone

I have a scanner for work (one that scans UPC codes and keeps track of how many). It has to hook into a telephone line in order to send information and for me to receive it. For the past few nights it keeps giving me the message, Error: no dial tone. I tried two different telephone cords, my telephone is working. What could it be and how could I fix it? Any ideas/suggestion? —Preceding unsigned comment added by 67.126.131.115 (talk) 19:16, 8 March 2008 (UTC)

If the outlet works and the cord works, blame the scanner. It must be broken. -- kainaw™ 19:43, 8 March 2008 (UTC)

Help - AOL Instant Messager (AIM) will not allow my to sign in

Hi; I have two linked accounts on AIM. I tried to log onto one a few minutes ago, and it would not work. I tried logging into my AIMail for the same account, and it also did not work. I logged into the second account and it was fine; however, I noticed two things. The first account was not displayed above the second account (as it should appear and always has), and when I opened an IM and attempted to use the first account, it was offline and unusable (even though it was selectable). Does anyone know what is happening here? The screen name and password are correct; I attempted signing in about a dozen times. Any help would be appreciated. Thank you. 70.105.164.43 (talk) 19:50, 8 March 2008 (UTC)

By the way, the error message displayed reads "Invalid Screen Name or Password". 70.105.164.43 (talk) 19:52, 8 March 2008 (UTC)

Sounds like an incident of hacking. Have you ever given out you passwords to anyone? You may wish to change the other's password if they were the same. I haven't used AOL since '00, but I think the master (or administrative whatever it's called...) has superiority over the other accounts, so was the other account your more important one? It sounds like you should call AOL support, and get them to reset the other password, though they had horrible service when I used it. Andrew Kanode (talk) 20:09, 8 March 2008 (UTC)

I've never given my password to anyone, but I do use the same one on other sites. Only two people know about the second account, and they are both completely trustworthy and aren't good enough with computers to hack/get my password. I made the second one about two weeks ago, and have used it maybe 3 times. I made the first in June and use it almost every day. One thing I forgot to mention was when I failed to login to AIMail, the message was "this action is unavailable at this time". Does this mean the problem is just temporary, or is it insignifigant? Thanks. 70.105.164.43 (talk) 20:22, 8 March 2008 (UTC)

Dizzler copyright vio?

Why does the website Dizzler.com still exist? I’m no expert, but it looks like it’s violating international copyright law. Why haven’t the record companies blown it out of the water? --S.dedalus (talk) 06:43, 9 March 2008 (UTC)

Wow, Froth, who knew you were an expert on international IP negotiations? "Lol" indeed! Actually the countries who aren't parties to international copyright treaties can be counted on a few hands and feet—it has nothing to do with loving the US's approach to things, it has to do with the US having made it a requirement to join the treaties in order to get the big-big money in US trade. The governments of most countries, quite rightly, see their own trade with the US as being more important than whether or not people can most pirated MP3s and movies around without a penny going to the content creator. (I think US copyright laws are draconian, but not for that reason. They're draconian because the copyrights do not expire in a timely manner, if at all. But the idea of copyright itself isn't so bad. People should be able to get paid for what they create.) In any case, Dizzler is registered in the USA, so yeah, US law probably applies. Dizzler itself says it adheres to the DMCA[3], and gives a very dubious legal justification for its action (it uses cases regarding image search engines to justify its own approach, and apparently disregards the Grokster ruling I mentioned above). --98.217.18.109 (talk) 22:25, 9 March 2008 (UTC)

Converting an mp3 into something readable

I have a short mp3 that I want to be able to play on an instrument myself. I've gotten most of it by ear, but a few chords are still off. Is there some way I could convert the mp3 into some format that shows roughly what notes are being played? HYENASTE 07:11, 9 March 2008 (UTC)

Not really, its a very tricky subject. You can play a midi keyboard into cubase or sibelius, and it'll notate it for you. However, it is often a confusing mathematical way of writing the notes, with excessive rests and dotted notes, something which still needs 'translating' into a decent readable score.

As for software that 'reads' an MP3, as far as I'm aware, it cannot be done, and if there is software out there, I doubt how good it is. Radiofred (talk) 14:49, 9 March 2008 (UTC)

Converting an audio file to a musical transcription is difficult for a computer to do. You can find programs for this purpose, but they really only provide useful results on audio recordings of a single instrument playing no more than one note at a time. For example, you can try the freeware AmazingMIDI, a WAV to MIDI converter, and see how it works for you.

An alternative approach is a program that assists you in analyzing the music, but ultimately leaves it to you to decide which notes best match the audio. I've tried a program called Transcribe! (30 day evaluation, $50 for one copy) that works in this way.

When you try to determine the notes on your own, it can be useful to slow the recording down without changing it's pitch. In Windows Media Player you can go to the View menu and choose Enhancements, Play Speed Settings. Or, if you use Winamp, you can install a plug-in called PaceMaker that can change the speed of files playing. Or you can use an audio editor to change the speed. For example, in Audacity, you can select a portion of the audio, then go to the Effect menu and choose Change Tempo. --Bavi H (talk) 01:03, 10 March 2008 (UTC)

Generally, most music recordings contain different combinations of sounds and instruments, many of which "overlap" - that is, their sounds share common frequencies. Whilst analysing the frequencies that make up these sounds is a trivial exercise (there are many programs like SPEAR that do it for you), getting a computer to identify the parts you want transcribed is the hard part. There is constant research in this area but as mentioned before, it's a tricky subject. Having said that, recordings of solo instruments are relatively easy to analyse since there is no other interference from other instruments. Chords are hard to determine because typically a musical instrument or sound will be made up of many different frequency components (which define its timbre), so you won't see three unique notes, but a wash of many at different amplitudes.

Unless of course the chord in question is played on an instrument that produces pure sine waves. Good luck! Damien Karras (talk) 13:36, 13 March 2008 (UTC)

Apache Tomcat?

Hi there. In the past I've used the Apache web server (with its PHP module) to run a hobbyist website. I've been without a computer and an internet connection for a while but I shall shortly have both back and will want to set it all up again. However, this time I shall also want to run some JSP / servlet thingies on a separate, private part of the website.

My questions are:

1 - am I right in thinking I can't do the Java stuff with just Apache?

2 - if I replace Apache with Tomcat then will Tomcat be able to do the PHP stuff?

3 - how much of a pain is running both Apache AND Tomcat?

Thanks! --79.64.51.58 (talk) 11:11, 9 March 2008 (UTC)

I don't know much about this but googling for things like "Apache JSP PHP" turns up a lot of hits. Apparently you can, with a lot of configuration, get Tomcat to do both PHP and JSP (see here); and apparently you can run both Apache and Tomcat at the same time, getting Apache to forward certain types of requests on to Tomcat (see here and here). Hope that helps. --98.217.18.109 (talk) 20:13, 9 March 2008 (UTC)

Previous poster is correct, you can get Tomcat to do PHP. For a site with more than a few hits the best option is to use a combination of apache tomcat and http server. You can achieve this with mod_jk, there are other ways too but this is the most common way. -- Q Chris (talk) 11:48, 10 March 2008 (UTC)

Finding out passwords

Is it possible for the system administrators/developers of a site to reveal the password of your user account? For example, can the developers of Facebook, Hotmail find out your password given your username? Similarly, can the developers of Wikipedia also find out your password? Acceptable (talk) 16:42, 9 March 2008 (UTC)

Most sites use a one-way hashing method to encrypt password. That is, they pick the password you choose, hash it to obtain a virtually unique string, and store it in the database. The next time you log, they hash the password you inputted and check if the resulting string is the same as the one stored in the database. This way, they don't have to store your real password (they have disclaimers that, once you forget your password, you lose your account).

So, don't worry, even if their databases are leaked, it is very possible they only store the hashed strings and not your password. -- ReyBrujo (talk) 17:00, 9 March 2008 (UTC)

Many sites store one-way hashes, and all sites probably should, but there are still plenty who do not. I got into an argument with the developer of a very commonly used forum software about this. He felt that a plaintext password was required so that he could e-mail your password back to you. I think that's chasing a bad reason with a bad reason. It is probably best to assume that your password is recoverable from any site. For what it is worth, the Payment Card Industry standards and OWASP recommendations require secure storage of passwords. There's no way for you, on the outside, to tell if a site is actually following those standards. --Mdwyer (talk) 21:31, 10 March 2008 (UTC)

But if you had hashed strings you could find out a lot of passwords using rainbow tables. You can pretty easily find out small, simple passwords in such a fashion. When you use very long passwords with non-standard characters, you make it a lot harder. (Unfortunately some sites don't let you use long passwords, even though they are much more secure than the most convoluted short ones against such an attack.) --98.217.18.109 (talk) 17:08, 9 March 2008 (UTC)

That is true. However, I assumed Acceptable was just wondering whether developers could just say "User X has password Y" without effort. -- ReyBrujo (talk) 17:15, 9 March 2008 (UTC)

They could, if they wanted to. There are rainbow table sites running things like ophcrack and things of that nature. Needless to say, one should be cautious in using the same password for everything. --98.217.18.109 (talk) 20:08, 9 March 2008 (UTC)

The md5 keyspace has been 100% indexed. There are fast (<5 second) lookup bots floating around IRC :D\=< (talk) 18:54, 10 March 2008 (UTC)

But they don't have to hash it- fact is, they have your password in plain text during the signup script, and if they don't hash it and throw it away like they should, they can do anything they want with it. My friend, a beginner PHP programmer, didn't even think to use hashes and could see any of his users' passwords in phpmyadmin. I wrote my own login script and hash the passwords with md5, but in the user manager I link the hashes to their lookup query on rednoize and most of the test accounts' passwords are in the hash database. :D\=< (talk) 19:45, 9 March 2008 (UTC)

And of course there is the worst-case-scenario of an unscrupulous programmer using their programs to just harvest passwords (e.g. [4]). --98.217.18.109 (talk) 20:08, 9 March 2008 (UTC)

They probably have it in plain text every time you sign in. It would be trivial to write a script that emailed a programmer a users password before hashing it. You cannot trust others to safeguard your password just because they have a website. So, always assume that the site is going to sell your account info for profit and give them as little as possible. -- kainaw™ 01:19, 10 March 2008 (UTC)

This is why everything except website logins uses techniques such as challenge-handshake authentication protocol: they let you prove you know the password without it ever leaving your computer. --12.169.167.154 (talk) 10:30, 10 March 2008 (UTC)

I think to summarise the answer is that if an organisation does the "right thing" and stores hashes with salt values, peer reviews deployed code to make sure input values aren't intercepted, etc. you would be safe. There is nothing to guarantee that they do any of this, so you should assume that your password is not safe. -- Q Chris (talk) 11:16, 10 March 2008 (UTC)

A friend of mine (and one-time Wikipedia high mucky-muck of some description) once ran a site popular among a certain audience. The user table stored hashes (wired up to the real login system in the correct manner as described above), but *also* plain-text passwords purely for his own perusal, interest and amusement. If you give someone your password, you give them your password - even if they have software acting on their behalf. 81.187.153.189 (talk) 22:58, 10 March 2008 (UTC)

Free the Space

G'day... My XP laptop reports a different amount of free space available on my external hard-drive compared to the Mac at work. I deleted a whole lota files at work yesterday... for eg. its stating 600Mb free on my XP machine while on the Mac it says 11.5Gb is free for the same partition. I've emptied both recycle bin and trash can without any difference. Cheers for any advice :1 Boomshanka (talk) 20:53, 9 March 2008 (UTC)

Are you sure that your external drive has a recycle bin and a trash can? I thought external drives do not have recycle bins. Kushal 05:07, 10 March 2008 (UTC)

That depends on how Windows recognizes it. If in My Computer it shows as a hard disk, then it has a Recycle Bin (\Recycled) and (sometimes) a System Restore Information folder. If it shows as a removable disk, then Windows doesn't create such folders. --grawity ^{talk / PGP} 16:20, 10 March 2008 (UTC)

So that means XP and Mac OS report deleted files differently? ...and so one OS would not recognise the fact the other OS had marked them as deleted. That makes sense I guess; ok, thanks Boomshanka (talk) 21:54, 10 March 2008 (UTC)

Laptop Screen Edges

The black screen edge on my toshiba by the logo has come loose for some reason.

Dual boot Xubuntu and xp - yet again

Hello, dear friends. Sorry for the abrupt disappearance a few days ago, but I've moved and my PC's not up to snuff yet, and I am still waiting to get a permanent Internet connection. Anyway, I'm getting a new hard drive, a 160 gig baby from Maxtor, and I want to divide it as follows:

• Linux partition - for Xubuntu probably - 20-30 g
• xp partition - for compatibility stuff if I need it - 20-30 g
• rest - data.

My questions as to this:

1. What to install first (Xubuntu preferred)?
2. How to order the partitions best?

It's gonna be safe - only Linux is gonna have Internet access :) anyway, suggestions welcome, all the best from the beautiful city of Olsztyn. --Ouro (blah blah) 16:16, 10 March 2008 (UTC)

Ey Ouro. Boo maxtor, yeeeeeah Xubuntu! This is how you want it:

Primary 1 - XP - 20GB

Primary 2 - /boot - 50mb or whatever

Primary 3 - Your data, format it fat32 if you need it at all from Windows. Don't trust wrappers.

EXTENDED

Logical 1 - / - 10GB?

Logical 2 - /home - 20GB

Logical 3 - swap - 2GB

--:D\=< (talk) 18:48, 10 March 2008 (UTC)

Oh and definitely install Windows first. And partition and format everything even before that from a gparted livecd, except leave unused space for the XP partition.. let the XP installer make its own NTFS partition in the empty space. :D\=< (talk) 18:51, 10 March 2008 (UTC)

Maxtors rock, Froth, been usin' 'em for years now. Anyhoo, I figured the gparted bit - always have it handy - and the fat32 bit, I was only unsure how to order the partitions around. Thanks loads! --Ouro (blah blah) 20:19, 10 March 2008 (UTC)

Pah, Western Digital is the best hands down. The order of the partitions doesn't really matter, other than that windows likes to be #1, /boot should be primary (don't think it HAS to be), and you can only have 4 primaries before you go to extended :D\=< (talk) 20:30, 10 March 2008 (UTC)

Make your data partition NTFS, as ntfs-3g is stable now. Or format it as ext3 and install ext2IFS (yes it works with ext3 is well) on Windows. FAT32 has lots of fragmentations and the 4GiB limit means you can't even store an image of a DVD. --antilived^{T | C | G} 05:45, 11 March 2008 (UTC)

I'm gonna be accessing my data mainly from Xubuntu, but there could come a time when I could need it under win (that's why I'm installing it - should I need certain software that's only available for windows). The DVD image is a point. Cheers, Ouro (when he was too lazy to log in). --83.9.68.252 (talk) 07:17, 11 March 2008 (UTC)

Mega Byte & Giga Byte

How many Mega byte equals 1 Giga byte? —Preceding unsigned comment added by 196.200.103.2 (talk) 18:04, 10 March 2008 (UTC)

Approximately one thousand megabytes is one gigabyte.87.102.94.48 (talk) 18:28, 10 March 2008 (UTC)

Exactly, not approximately. We have names now. :D\=< (talk) 18:40, 10 March 2008 (UTC)

If you think megabyte is 10⁶ bytes and gigabyte is 10⁹ bytes, then you have 1000 megabytes = 1 gigabyte. If you think megabyte is 2²⁰ bytes and gigabyte is 2³⁰ bytes, as you often do, then you have 2¹⁰ megabytes = 1024 megabytes = 1 gigabyte. Read megabyte and gigabyte. --212.149.216.233 (talk) 18:45, 10 March 2008 (UTC)

A gigabyte is not 2³⁰, that would be a gibibyte. :D\=< (talk) 18:49, 10 March 2008 (UTC)

Nevertheless, Gigabyte is in common usage, often where gibibyte is the defined correct term.

To the original poster (Hello!) Our Gigabyte article explains some of the confusion. AlmostReadytoFly (talk) 19:13, 10 March 2008 (UTC)

You link to Gibibyte, and yet you missed the "gigabyte... can... be a synonym for gibibyte". Megabyte has been used as $2^{20}$ for quite some time, and even now it is not incorrect usage (unrecommended, maybe). -- Meni Rosenfeld (talk) 19:24, 10 March 2008 (UTC)

Just when I thought computers couldn't get any more confusing. I understand it all, but I can see how a layperson would have a major headache when trying to buy a computer. 206.252.74.48 (talk) 19:26, 10 March 2008 (UTC)

Simply speaking, you can usually think about it as 1024 Megabytes in a Gigabyte. Useight (talk) 01:01, 11 March 2008 (UTC)

The gigabyte/gibibyte distinction is usually not meaningful for things like buying a computer. When you're comparing components (how much hard drive space or RAM, for example), the same unit will always be in effect. Hard drive space is almost always specified in base-10 gigabytes, while RAM is always specified in base-2 gigabytes, so unless you're actually doing capacity planning where you know your needs more specifically than just "bigger is better", they may as well call the units of RAM potrzebies or something.

The average user can safely forget about the SI prefixes, IMO. I've been in the software biz for many years and have never once heard anyone using "gibibyte" and friends. A google search for megabyte gives millions of hits, while a search for mebibyte gives around 36,000 -- and almost all of them are about what it is and why no one cares. :) --Sean 13:06, 12 March 2008 (UTC)

Enemy Territory

I hate buying presents, but it seems I soon have to. The one for which I should get something always complains that Wolfenstein:Enemy Territory doesn't run well on Windows Vista. I think he should have upgraded his games instead of going for Vista. Then a day ago I stumbled upon Super Gamer LiveCD that has it. It looks like quite perfect (=free), but download size is huge for my <60kB/s download rate. Is there something similar out there that would be a bit more minimal that has/on which can be installed Enemy Territory (yes and also put on something I can just handle over)?

A DVD is not too big for 60kB/s. In round figures, it would take 100,000 seconds to download 4 gigabytes at 40 kilobytes per second. That's 1667 minutes. 27 hours. Just over a day.

Good Star-watching Software

Ages ago I got a Meade Polaris telescope as a gift, and it came with some great astronomy software called "Starfinder" on 2 floppy disks. But alas, I have lost those disks and am having trouble finding a program that is as good as it. Can anyone lead me a website where I can find it again, or recommend any software that is simular to it? Specifically, I am looking for the following features:

-Simple rendering of the ground and the horizon (so I know what I can and can't see!)

-Symbols and labels (instead of fancy rendering like Celestia)

-A "nightvision" mode that makes the entire UI red-coloured to preserve vision in the dark (this is the most important feature)

Thanks in advance. 206.252.74.48 (talk) 19:14, 10 March 2008 (UTC)

I had that exact software with those same 2 floppy disks O_O I was like 8 years old and I loved flicking nightvision on and off :D It was just tweaking windows "Appearance" tab settings though.. you could probably tweak your own and save it as a template then restore that every time you go stargazing.

Hard drive and RAM measurements are basically an estimate. It is nigh impossible to get an accurate number for storage. The explanation may also lie with the fact that hard drives store data in "clusters" of a certain size. This means that some space cannot be used. It is better with NTFS than it is with FAT32, but you will still lose some storage space as a result. There is also LarryMac's answer, which is part of the problem as well. So, it is both an issue of size labeling as well as the restrictions of data storage methods. 206.252.74.48 (talk) 20:18, 10 March 2008 (UTC)

What you're describing is internal fragmentation, and is why you won't be able to fit 79,993,765,888 bytes of data on your 79,993,765,888-byte hard drive.

It is an 80 gigabyte drive. It's also 76 gibibytes. Gibibytes are a different unit. You didn't lose anything. That's like saying you lost 9 of something in going from 100 yards to 91 meters. Yes, the hard drive manufacturers and the software manufacturers should get together and agree to use the same units. They should both use gigabytes, because it's a more sensible unit.

Software to save memory of an application

I wonder if there are apps that can "save" the memory usage of another app so that the memory can be loaded back later and the app would think its at the point it was at during savetime.

For example, ability to "save" a dos game that doesn't have a save option.

I need it to be runnable under WinXP.

Thanks!

Perhaps there are some debuggers or dump applications that can do that. One issue is preserving the state of all the gadgets in the PC such as the interrupt timer, video memory, sound card etc. Under DOS there is more direct control by programs and so it will be more tricky to interrupt and restore control later. Graeme Bartlett (talk) 04:11, 11 March 2008 (UTC)

If possible, it would be an acceptable option for me to preserve not the dos prog itself but an emulator running it, such as doxbox. Of course I have no idea what kind of cans of worms that option can open... 24.83.195.130 (talk) 04:14, 11 March 2008 (UTC)

One option that may be overkill but which is guaranteed to work is to use vmware server (which is free). You could run freedos or windows in the virtual machine. Vmware server allows you to suspend the state of the machine and restart it later. Morana (talk) 10:29, 11 March 2008 (UTC)

Toshiba Laptop switching itself on

Last night my fiancé's Toshiba Satellite M30 laptop switched itself on in the middle of the night, despite the fact that she put it in standby mode before going to bed. She got up in the middle of the night, saw a glow coming from the screen, and for some reason it was on, so she had to shut it down again. We'd both been up before then and it was definitely off, so we're somewhat confused. It's actually the second time it's happened. She's worried that it may have a virus and someone is accessing it while she sleeps, and while I know this is unlikely, I can't explain what's happening. Can anyone help? Is there a known explanation for this (other than 'are you sure you turned it off?')? Thanks in advance! Phileas (talk) 12:54, 11 March 2008 (UTC)

I need a textfile splitter

OS: Windows XP

I have thusands ASCII plain text files. Each file consists of up to hundreds of documents. Each document ends with "END OF DOCUMENT". Some individal documents are more than 500 KBytes. Some files are several MBs. These are very large text files.

I need to split the files into separate documents and save them. Naming is not an issue because I can rename them later. They can be indxed by a desktop search engine.

I tried TextWedge. It is buggy. From time to time it fails to split the documents properly. I have no idea why some large files are correctly splited while some others are not.

Is there a good tool for this job?

Most text splitters only split files by size or by line count. Many of them do not support drag-and-drop, batch or multiple files. Some shareware products are simply crap.

I can actually use a line splitter to do this job. I can batch replace all /n to a placeholder and then add /n before and after "END OF DOCUMENT" so the file would look like:

1. Very lengthy single-line document 1 ... blah ... blah ... blah ... /n
2. END OF DOCUMENT /n
3. Very lengthy single-line document 2 ... blah ... blah ... blah ... /n
4. END OF DOCUMENT /n
5. Very lengthy single-line document 3 ... blah ... blah ... blah ... /n
6. END OF DOCUMENT /n
7. Very lengthy single-line document 4 ... blah ... blah ... blah ... /n
8. END OF DOCUMENT /n
9. Very lengthy single-line document 5 ... blah ... blah ... blah ... /n
10. END OF DOCUMENT /n
11. ... /n

Then I can split the files every other line. I can then restore /n.

Are there GOOD tools for this job? -- Toytoy (talk) 18:12, 11 March 2008 (UTC)

It would be trivial to do this with a programming language like C, Pascal (Delphi), (Visual) Basic or Perl. I take it you don't know any? I suppose it can be done with a tool that supports macro scripting but I would not be bothered with the effort. I also would not trust shareware to do this. Backup your files! Sandman30s (talk) 18:20, 11 March 2008 (UTC)

I'd use csplit. I think it is a standard BASH command. I'm sure there are a million other ways to do it. -- kainaw™ 18:23, 11 March 2008 (UTC)

Right, the problem is that the task you want done is highly specific to your particular needs, though the ways of doing it are relatively easy with scripting languages, so there's not going to be some sort of not-quite-scripting solution out there for this particular task.

Given what you've told us the easiest way to do it will probably be in Visual Basic, just because you probably already have programs with VBA interpreters in them (e.g. Microsoft Office), so you won't have to install anything new, and VBA (of this sort) is relatively easy to read comparative to other scripting languages. Perhaps someone on here will take the time to write out the code for you but basically what you want to do is have it go through every file in a directory, open the file, loop through the lines of a file and see if it equals END OF DOCUMENT or not and if so take the lines since the last END OF DOCUMENT and put them in a new file (named?). I haven't written VBA in awhile so if I try to do it from scratch it'll probably be buggy (and I don't have time to really try it out), but it's not hard to do if you can find someone who knows VBA. --98.217.18.109 (talk) 18:28, 11 March 2008 (UTC)

If you grab ActiveState Perl the following command will do the trick:

perl -ne 'sub bump { open STDOUT, ">out" . ++$i . ".txt" } bump unless $i; bump and next if /END OF DOCUMENT/; print' in.txt

Anasoft Licence Manager? Nitrogen service? Anybody heard of?

Other than the fact that the software package -"Anasoft License Manager"- was assigned TCP ports 1083 and 1084 in the IETF's old "Well known ports" list -which makes said package at least 15 years old- a quick Google search doesn't turn up much that's useful.

Windows Vista, suitable directory for standalone command line utility

I'm trying to help my father-in-law, who bought a new PC with Windows Vista, to get a command line utility working. I've never touched Vista. His hearing isn't too good, and he lives in a different city, so this is (a rather difficult case of) telephone support. So far, he has managed to copy the .exe file to a usb-stick. The question is, where to put it. On XP, I'd simply drop it in C:\Windows or C:\Windows\System32. Is the directory setup the same on Vista, and if so, would copying it there work as it would in xp? Otherwise, what would be the easiest solution? Having him create a directory for it, modify the PATH environment variable etc. to make Vista aware of the program would be *very* difficult. --NorwegianBlue ^talk 19:52, 11 March 2008 (UTC)

I believe command line support was removed from Vista. ArcAngel (talk) 21:17, 11 March 2008 (UTC)

It's still there, just less obvious. Either hit start and search for 'cmd' or go to all programs->accessories->command prompt. Anyway, I just checked the directory structure on my Vista box, it's the same as XP - those paths are still good. Not sure if UAC would take too kindly to it, but unless it does really wierd stuff, it should be fine. What does this program do? CaptainVindaloo ^{t c e} 21:29, 11 March 2008 (UTC)

It's good old grep, which he uses for searching his genealogy data base (a huge collection of huge text files). Unfortunately, the fact that he's working from the command line does not imply that he's computer savvy, just that he started doing this on a CP/M machine... On Vista, we had a hard time even launching a shell, but this site came to the rescue. Will we be able to copy the .exe to c:\windows from an ordinary dos shell, or will we need a shell with special privileges? If special privileges are needed, can these be acquired once the shell is launched (like su in unix)? --NorwegianBlue ^talk 22:04, 11 March 2008 (UTC)

I think maybe I found the answer to my preceding question in a subpage of the site I linked to, but I'd be grateful if someone would check it out and confirm:

1. Logon to Vista using your normal username and password.
2. Click on the Start button
3. Click on Start Search.
4. Type, cmd.
5. Right-click cmd, select 'Run as administrator' from the shortcut menu.

In the last step, what exactly is meant by right-clicking? Clicking on the blank background of the shell, on the icon at the top left of the window frame (system menu) or something else? If you're thinking, "well why don't you try?", remember: I cannot see the machine, the gentleman I'm trying to help does not communicate very clearly what he is doing, and has problems in hearing what I am saying. --NorwegianBlue ^talk 22:20, 11 March 2008 (UTC)

That's right, I was just typing up a response to say the same thing. You need to close the command prompt, right click the command prompt icon and select run as admin from the menu. Provided the text files are in his workspace (C:\Users\username), there shouldn't be any more problems from here. CaptainVindaloo ^{t c e} 23:04, 11 March 2008 (UTC)

You definitely should not need elevated privileges to grep. :D\=< (talk) 01:49, 12 March 2008 (UTC)

Clearly not, the question was whether you need elevated privileges to copy grep.exe from the usb-stick to C:\windows. CaptainVindaloo, you're saying that you need to right-click the cmd-icon in the start-menu, right? Is there no way to elevate the privileges of a shell that is already running? --NorwegianBlue ^talk 12:54, 12 March 2008 (UTC)

Yep, it's the start menu icon you're after. I don't think there is a way of elevating cmd's permissions while it's still running. Sorry Froth, I didn't mean to imply you needed elevated permissions to use grep, I just meant you just need it once to install it in system32 without aggroing UAC.

Python: extreme index

My Python-fu is rusty, and I've had surprisingly little luck with available documentation. What's the "standard" way to find the index of the lowest (or highest) element in a list? —Tamfang (talk) 20:57, 11 March 2008 (UTC)

Something like L.index(max(L)). --71.162.233.151 (talk) 23:03, 11 March 2008 (UTC)

Okay. Seems inelegant, though, as it involves searching the list twice. —Tamfang (talk) 23:38, 11 March 2008 (UTC)

You could just do it the real way and loop through L, keeping track of the index and highest value. Probabaly no slower than using max() unless functions aren't actually interpreted on the fly, I have no idea how python works :D\=< (talk) 01:14, 12 March 2008 (UTC)

My goodness, are you suggesting that a programmer actually should manually loop through a list in python! Heresy! Python people are crazy-lazy, I'm just sayin'. It's like two lines, fer chrissakes! --Oskar 10:34, 12 March 2008 (UTC)

Using builtins will almost always be faster than coding it explicitly, since the builtins are written in C. The following program shows the builtins (even with the double-lookup) to be 4 times faster than searching the list explicitly. --Sean 14:36, 12 March 2008 (UTC)

#!/usr/bin/python

import random, time

list = [random.random() for x in range)]

iterations = 1000
start = time.time()
for i in xrange(iterations):
    list.index(max(list))

end = time.time()
per = (end - start) / iterations

print "%f seconds per loop with builtins" % per


start = time.time()
max_idx = -1
max_val = -1
for i in xrange(iterations):
    for idx in xrange(len(list)):
        if list[idx] > list[max_idx]:
            max_idx = idx

end = time.time()
per = (end - start) / iterations

print "%f seconds per loop by hand" % per

I get 7.3 times faster, and yet another 10% slower if I actually implement the max_val "optimization" you implied that loads each element of the list only once. With -O and (of course) a different list, I get 6.1 times faster, and 8% slower; the index() solution, of course, only has to rescan a random-length prefix of the list. It's amazing just how much slower Python is than C — even C that has to test the type of each list element and so on. Of course, no index manipulation has to occur, and I guess the interpreter doesn't even know that xrange isn't modifying the list... --Tardis (talk) 23:34, 12 March 2008 (UTC)

Of note - the search tool in Wikipedia is terrible. You are better off going to Google and seraching "large archive sharing and rights management site:wikipedia.org". As for the topic, I am confused. The name of the section here is distributed computing, which is a method of running a program such that different parts of the program run on different processors, all running with a common goal for the overall program. Then, your question appears to be about large archive sharing, which I use a NAS for. Also, you mention what appears to be file system permissions. None of those topics really have a lot to do with one another. So, I'm not sure what you are asking about. -- kainaw™ 12:06, 12 March 2008 (UTC)

And there is no reason to assume Google is anything more than the flavor of the moment. The number 1 search engine comes and goes.

Instead, it makes it very easy to choose to search with google after you click the "search" button. -- kainaw™ 00:06, 13 March 2008 (UTC)

Several (three or more) years ago lengthy watchlists were a real issue, with occasional database slowdowns getting so bad that the developers had to institute severe limits on the "view my watchlist" query (not on the watchlist you actually have, but on the maximum number of watchlist changes you could see), down as few as 20 one time. Subsequent (software and DB structure) improvements seem to have mostly fixed this problem. A few times the devs have complained that people running semi-automated queries with URLs manipulated to request very large datasets have made the servers slow, but I've not seen that lately either. Most large database-backed websites eventually institude mechanisms to cull any user-generated query that's taking more than a reasonable one should (say a second or two), to limit the asymmetric leverage available to DoS-ers; I don't know of WikiMedia has done this on their MediaWiki/PHP/MySQL setup. -- Finlay McWalter | Talk 17:57, 13 March 2008 (UTC)

The Evils of Geek Squad

A few weeks ago I asked about what was wrong with my ThinkPad and from the answers I've decided to hand my laptop over for repairs. Since I have no warrenty or anything of the sort (and I'm lazy and impatient), I'm thinking of going over to Geek Squad (which I can literally hit with a stone throw from my home) and entrusting it to their care. However, my friend told me he hates Geek Squad because they just send it back to the manufacturer - who replaces the components with cheaper ones. I really don't want to go to the local mom and pop computer repair shop (although normally I would, but this particular one charges ridiculous prices), so I'm wondering if this is true. 206.252.74.48 (talk) 14:39, 12 March 2008 (UTC)

Circuit City's Firedog is better than Geek Squad. Personally, I'd fix my computer myself and take the opportunity to throw that stone you speak of at Geek Squad.

Every time someone asks me to repair a laptop, my solution is to send in all the guts and replace them. I'm not going to waste time poking around in those mini-components. Now, if it was a real computer, I'd happily open up the case and try to figure out specifically what is wrong and replace it with possibly better parts. So, I would expect any repair shop to do the same thing. Just swap out the guts for whatever they can find. -- kainaw™ 16:23, 12 March 2008 (UTC)

Why are some of you complaining that I have a laptop? I have a desktop, and I do repair it myself. I have a laptop because it is very useful when I'm running my D&D campaigns. Like Kainaw said, everything is too damn small to mess around with. As for Firedog - the Circuit City that I could throw a stone at has turned into a restaurant, and the nearest one is 20 minutes away.

I love the anti-laptop sentiment. Nothing more entertaining that irrational discounting of an entire category of machines on the sole basis that their compact nature makes them harder to repair, as if that were the sole deciding factor in purchasing a computer. (But not impossible. You can often find very wonderful and detailed instructions online about what order to remove things and then it's just a case of keeping track of all the screws. I've taken apart iBooks, Powerbooks, and Macbooks multiple times. It's not that hard once you've done it once and have a general idea of where everything goes. You just have to be more organized than a desktop, which you can rip into without paying much attention to what you are doing.) --98.217.18.109 (talk) 22:47, 12 March 2008 (UTC)

The anti-laptop sentiment is understandable. It comes from dealing with people who do not take their needs into account when purchasing a computer. They spend twice the money on a laptop with half the capabilities of a desktop and then never, under any circumstances, move the laptop off their desk. It isn't just limited to computers. A coworker just purchased a blackberry pearl. I asked if she liked the email reader. She said didn't get email service with her plan. I asked if she liked the web browser. She said she didn't get internet service with her plan. I asked what she had. Just telephone. So why, I wondered, did she buy a blackberry? Because it is the cool thing to do. -- kainaw™ 00:03, 13 March 2008 (UTC)

It's ridiculous to assume that just because someone has a laptop they aren't using it as a laptop. If you've been around a university in the past four years, for example, you'll see that laptops greatly outnumber desktops because the latter force you to be bolted in one location to get any work done. In any case, berating someone for buying a laptop when they are asking about where to get it repaired is a bit like, well, something terribly unproductive, and the sort of smarmy thing that tech-savvy people do that makes the non-tech-savvy think they are all pricks. --98.217.18.109 (talk) 00:51, 13 March 2008 (UTC)

Personal story time: I bought a laptop once, and I used it roughly as many times. There's no doubt there are people to whom laptops are invaluable, but I think that too many misidentify themselves as such. For me, having a reliable, comfortable, powerful and affordable bolted-in station for serious work & play, and a book for when I'm on the go, is a wonderful arrangement - and I think it should be satisfactory for most. -- Meni Rosenfeld (talk) 11:29, 13 March 2008 (UTC)

I see no reason the card shouldn't work on either of the boards. The P5KC doesn't support SLI, though. Its main advantage is that it supports both DDR2 and DDR3, but I don't think this is all that beneficial. -- Meni Rosenfeld (talk) 21:10, 12 March 2008 (UTC)

The 9600GT requires an extra power connector that you should make sure your PSU has. It needs a 6 pin molex connector but depending on the brand of graphics card you have it should come with an adaptor for a standard 4 pin molex connector of the sort you'd use to power an IDE hard drive. The motherboards you have posted are fine by the way, and will work with the 9600GT TheGreatZorko (talk) 13:56, 13 March 2008 (UTC)

Download Wikipedia

Hello,

On an unrelated subject I've always wondered if it were possible to download the entire of wikipedia (for arguments sake lets say I have a computer that is capable of holding and running this download of wikipedia). I would imagine that the process would save the entire of wikipedia as it is in that state and then transfer the data.

Just Wondering

100GB! That's a lot of space to dedicate. Even though my PC's capacity is 1.1TB, I can't imagine a need to have Wikipedia offline that merits the use of 100GB. Useight (talk) 21:20, 12 March 2008 (UTC)

the purpose of binding a socket to an address

In standard unix programming, what is the purpose of binding a socket (via the bind(2) command) to an address? I can see why one needs to bind to a certain port, obviously it is to tell the socket to listen on that port, but why give the option of an address? --Iownatv (talk) 01:22, 13 March 2008 (UTC)

It is possible to have multiple addresses on a single computer. You need to be able to tell the computer which address to use. -- kainaw™ 01:29, 13 March 2008 (UTC)

what else than 127.0.0.1 would it be? the local loopback. I thought it was uncommon in code to know what one's own address is. —Preceding unsigned comment added by Iownatv (talk • contribs) 01:43, 13 March 2008 (UTC)

If you were using it as a server, you could use a different IP for each service: Web, FTP, SMTP, etc. If your network is divided into subnets, the you could assign an IP for each subnet. --— Gadget850 (Ed) ^talk - 01:54, 13 March 2008 (UTC)

(ec) You appear to be thinking along the lines of desktop computers. I work primarily with servers. Two quick examples of multiple IP address uses:

• Server has a network connection to the world with an IP address of something like 11.22.33.44. There is a mirror server sitting right by it that the main program copies all changes to. The mirror is connected on a separate network connection with a fake address like 192.168.0.1. The program handles real-world activity on, say port 123 address 11.22.33.44. It talks to the mirror on, say, port 777 address 192.168.0.1.
• You have three websites on one server. Each requires SSL. Since the SSL handshake takes place before the hostname requested is given, you have to give the server three IP addresses. Each one requires a unique certificate for SSL. So, you listen on port 443 address 11.22.33.1, port 443 address 11.22.33.2, and port 443 address 11.22.33.3. Since you can uniquely identify which address is hit, you know which certificate to use.

There are many other reasons to use multiple IP addresses on a single server. I'm sure you can quickly think of a few. -- kainaw™ 01:56, 13 March 2008 (UTC)

TI-BASIC semicircle

Or not- it's a graphing calculator just graph the equation- it's going to be a lot faster than plotting individual points in BASIC.

You need to write the equivalent of:

x=x value of centre of circle !insert a value here

y=y value of centre of circle !insert a value here

a=angle that semicircle will make to the horizontal !insert a value here

r=radius of circle !insert a value here

For n=0 to pi step (1/(2 x pi x r) !use radians or change pi to 180 if you are using degrees

plot {x + r cos (n+a) , y+ r x sin (n+a)} ! plot each point

next n  ! repeat for all the points

stop

If you don't have a for/next loop use an 'if' statement and a loop

It should be easy for you to convert this to TI-84 syntax

If you can do that it would be interesting to look at Midpoint circle algorithm which is almost always a faster way to do it..87.102.8.240 (talk) 10:18, 13 March 2008 (UTC)

SMS Gateways: How can I send an SMS text message via email to a Korean cell phone?

In the US, almost all cellular service providers have an e-mail address associated to each cell phone to send text messages to the phone via e-mail (e.g., number@messaging.sprintpcs.com for Sprint, number@txt.att.net for AT&T, etc.). How can I do the same with Korean cell phone companies (SK, KT, LG)? I haven't found much information about Korean cell phone SMS gateways. I would rather use the actual telecom if possible, rather than a third party service, to avoid number harvesting. —Preceding unsigned comment added by 66.75.102.95 (talk) 03:05, 13 March 2008 (UTC)

Wow that would be quite a useful feature, are the txts sent through email free to receive? From your description it seems like that the company merely sends the content of the email through SMS to your phone so as long as the phone is compatible to SMS I don't see what's the difference between a Korean cell phone to other cell phones. --antilived^{T | C | G} 05:16, 13 March 2008 (UTC)

With Sprint, in the US, e-mailed texts cost the same to send/receive as any domestic texts. It is really great, however, when sending international texts. Instead of being routed through the phone company's private networks, and being subject to international text fees, they are sent over the public internet as e-mail, so they just cost the same as a regular domestic text. The problem (which I'm trying to solve) is figuring out what the SMS gateways are for Korean mobile telecoms. I found that SK has a data service called NATE which may be in charge of their SMS gateways (if they even have any), since I've found a few Google results with the number@vmms.nate.com syntax. However, sending texts to a few friends using SK in Korea gets me an SMTP delivery failed response when sending from both my phone and my e-mail client on the computer. Unfortunately, I can't read Hangul, so I can't go through the nate.com site, which is all in Korean, to see if they have any support pages that could give me some more information. :( 66.75.102.95 (talk) 16:09, 13 March 2008 (UTC)

"Upgrade" to XP Pro?

Honestly, I should know this but I've been a little stumped with it recently. I recently (Christmas time) received a new Gateway P-6301 with Windows Vista Home Premium pre-installed on it. The computer's hardware is all still factory, with the exceptions of a few scratches. Heh. Anyway, without having to go through 10 acts of Congress could someone please tell me if there's a fairly simple and hassle-free way to upgrade to Windows XP Pro from pre-installed Vista? crassic!^[talk] 04:48, 13 March 2008 (UTC)

Do you have a copy of Windows XP Pro? If so, I don't think there should be a problem at all - just install XP as usual and format the drive. If you are asking about getting an XP license cheaper based on your current Vista - I don't know, but a quick search at Microsoft's site (for some reason they call moving from Vista to XP "downgrading") reveals some seemingly relevant results. -- Meni Rosenfeld (talk) 11:07, 13 March 2008 (UTC)

I technically don't own a copy, but I have a copiedLEGAL! disc with a good key. When I insert the disc, the option for installation is shaded over. And booting from the CD (as it doesn't want to work otherwise), I attempted to install but, of course, it just effectively ruined my current OS by removing NTLDR (and likely other key files.) crassic!^[talk] 01:43, 14 March 2008 (UTC)

Yeah you're supposed to boot from the disk .. :D\=< (talk) 03:59, 14 March 2008 (UTC)

The trouble with that (just installing XP as usual) is that it consumes a licence (so you've paid for Vista, and paid for XP, but are only using one). As the Vista licence Crassic has is a Gateway OEM licence, he should approach Gateway and enquire about their Vista->XP migration options. Microsoft does allow OEMs to offer this capability (and I think provides them with some tools to that end), although they don't exactly shout it from the rooftops. I'd also check that they'll allow a return to Vista at some future time when Vista is actually finished. The other programmes I've seen (I don't know anything about Gateway's) allow you do all this on one licence without any (financial) cost. -- Finlay McWalter | Talk 11:53, 13 March 2008 (UTC)

Vista's perfectly fine if your computer doesn't suck- yours unfortunately does. What's with all the vista bashing? You're not hard or something if you stay with XP (after all, it's all Windows garbage)- XP is stable but sorely out-of-date, which is painfully obvious every time I have to work with it. Vista's a memory hog but it's a far more mature OS than 7-year-old XP. Or switch to linux and dual boot XP for gaming- for its lower memory overhead. :D\=< (talk) 13:20, 13 March 2008 (UTC)

You would want to make sure that XP drivers are available for all of the hardware in your Gateway, which I understand can be an issue. --LarryMac | Talk 13:19, 13 March 2008 (UTC)

My computer isn't really terrible, I honestly just believe Vista is too much of a hassle to deal with currently with all of the bugs. And having to reinstall often isn't much fun, since I've heard a few of my friends have had to do it as well. crassic!^[talk] 01:43, 14 March 2008 (UTC)

Vista isn't actually a memory hog, and I wish people would stop calling it that. It uses about 50mb more than XP SP2, with only its services running. The rest that you see in the task manager is something called Superfetch which means Vista puts programs it thinks you might use in the RAM so they launch faster. If another program requires that memory then the Superfetch cache is emptied, and the other program is allowed to use it as normal.

However Vista runs a lot better on 2GB of memory than the 1GB that you have (It still runs fine on 1GB of memory so I'm not sure why you want to switch). You could probably buy another 1GB stick of laptop memory for less than the price of a copy of XP Pro. TheGreatZorko (talk) 13:50, 13 March 2008 (UTC)

DWM.exe often sits around at 30-50MB, which is hardly sucking all my memory, if that's what you are implying. Oh and turning off Aero gives you almost no speed boost by the way (because it's all done on the graphics card, and is turned off or frozen when a 3d application (or something that demands the use of the graphics card) has focus), so if you can run it you may as well keep it.

My computer is an Athlon FX-60 2.6GHz Dual Core, 3GB RAM, 1.1TB HDD, 8800GTX 768MB video card, so I would call it a gaming machine. And you want to know what OS I'm running? Windows XP Pro.

Why don't you like Vista? Nvidia driver support is finally ok on vista.. :D\=< (talk) 16:46, 13 March 2008 (UTC)

Many reasons. Memory hog (even if that is just RAM being loaded with programs it thinks I might open (I'll open it when I want it)), slower boot time, annoying "Are you sure?" messages, the start button is now a circle that doesn't say start, driver incompatibility, takes up more hard drive space. Useight (talk) 02:08, 14 March 2008 (UTC)

Come on, think about it. Intelligent caching is exactly what you want. Firefox is already loaded in my memory even when it's not open. If I need to run firefox, it loads pretty much instantly. If I need to run anything else, that just writes completely over the cached memory. It's that simple- that memory just gets wiped immediately if you need it for anything else. So while it looks like you only have 5% memory free, half of your memory is actually superfetch and is released the instant you need it. Disable UAC (just don't run untrusted code; UAC isn't going to protect you from something malicious) to turn off the annyoing popups, disable unnecessary services just like you would in XP to speed up your boot/shutdown. Driver incompatibility isn't an issue anymore unless you're trying to downgrade to XP, in which case you have to check for driver compatability. You're right about hard drive space. :D\=< (talk) 03:08, 14 March 2008 (UTC)

Note: My computer isn't actually that terrible, though it is factory. 160 GB hard drive (250 GB external), dual 1.46 GHz processor (533 MHz FSB) with 1 MB level-2 cache, 1 GB DDR2 memory. The only thing I dislike about it is the video card, Intel should stop integrating their cards on every machine ... though I could understand it with a laptop (Graphics Accelerator X3100 with up to 384 MB of DV memory.)

Converting Outlook mail to Mbox

Hi. I am trying to import my mail from Outlook to Mozilla Thunderbird. If I use Thunderbird's import feature, any international character in the bodies of some messages becomes corrupted (and no character encoding tweaking on Thunderbird's end will help). If I import to Outlook Express and then to Thunderbird, the subject lines become corrupted on the Outlook -> Express step.

So, does anyone know a solution to this problem? Perhaps some script I can run that will hybridate the correct subject lines from one version of the mail with the correct bodies of the other? Or a different program to do the conversion? I have encountered an Outlook plug-in called MessageSave that can do the trick, but its trial version is too limiting and its full version is too pricey. Does anyone know of a free alternative, or at least one with a better cost / value?

Thanks. 79.178.115.92 (talk) 11:19, 13 March 2008 (UTC)

I've used Aid4Mail (which is commercial, if not terribly expensive) to interchange mail from a variety of formats, and in particular moving Outlook PST archives (which are its equivalent of MBOX files) to EML files that Thunderbird will read (so I'd have Outlook export a folder or account to PST, then have Aid4Mail turn them into EML files). While there are some open source libraries that claim to read Outlook's proprietary formats (and the different, incompatable, and proprietary Outlook Express formats) they don't appear to be heavily maintained and the tools that use them don't seem terribly effective. Update: Ah, I checked MessageSave's price, which is the same as Aid4Mail, so maybe this isn't what you're looking for. -- Finlay McWalter | Talk 11:30, 13 March 2008 (UTC)

Well, on one hand, Aid4Mail can do a lot more than MessageSave. On the other hand, it seems to still have problems with some of the messages. Since all I want is to convert my mail to mbox and forget any other format ever existed, I've decided to purchase MessageSave. Thanks for the help. 79.178.115.92 (talk) 14:31, 13 March 2008 (UTC)

Aid4Mail is great if you, like me, were going to be exchanging mails in various formats on a regular basis; it's a sorry state of affairs when someone who, like yourself, has to buy software just to get control of their own data for a one-time migration. If you're up for a bit of labour, you could try the following: get yourself an IMAP email account and configure both Outlook and Thunderbird to access it (Outlook, as usual, will try to do vexing things like download all the mail unless you make sure it knows not to). Then, in Outlook, drag your emails (ideally en-masse) from your existing account to the IMAP account (it should copy them up). Then, when they're all copied, use Thunderbird to drag them back down from the IMAP server to a local thunderbird folder (or you could choose to keep them in IMAP land permanently). -- Finlay McWalter | Talk 18:10, 13 March 2008 (UTC)

Bluetooth is a short-range (10 or 100 m) wireless connection, usually between two mobile phones.

There are programs that let you control other phones via Bluetooth - steal phonebooks and SMS, play sounds, call someone, usually without phone owner's knowledge.

The program you linked to claims to do exactly that, but:

• The screenshots (pictures) are actually from other programs. I've recognized BloooverII, BT Info and EasyJack. So in fact they're selling programs which are created by others and available for free.
• The website's design is AWFUL. I don't trust any website which has such design.

In short, it is a scam.

If you have a phone with Bluetooth (and know how to use it), download BT Info (click "ftp_bt 1.08") and copy it to your phone. --grawity ^{talk / PGP} 08:46, 14 March 2008 (UTC)

Isn't Bluetooth communications encrypted precisely to prevent this sort of thing? Why would anyone use it if this is possible? -- Meni Rosenfeld (talk) 10:48, 14 March 2008 (UTC)

Yes, Bluetooth is encrypted, but the idea is that if you connect ("pair") two devices, for example, your and my phones, they both trust each other - I can connect to any paired device and most of them either do not ask owner for permission or are set to "always allow". Also, you can set your device name to "Enter 1234", go into a mall, and try to pair with everyone (using PIN 1234).

So now our devices are paired, and your phone allows mine to connect - and I do. You probably click "Allow" before even reading that darn popup which just appeared, and then I have absolute control over your phone. (That is, while your phone is in the range - 10 meters, or in some phones 100 m.) I can make your phone call me (and listen to whatever you're doing), I can change language (to Chinese for example), start a MP3, edit phonebook.

The problem is that you're not supposed to add a device if you don't trust its owner. --grawity ^{talk / PGP} 14:50, 14 March 2008 (UTC)

Simulating PowerPoint's increase/decrease font size features in OpenOffice.org Impress

In PowerPoint, you can select a block of text and adjust the font size (upward or downward) by clicking the "increase font size" or "decrease font size" buttons. These buttons increases/decreases the font size of the selected text to the next predefined font size in the "font size" dropdown list. If original font size is between two predefined font sizes, the adjusted font size will be between two (new) predefined font sizes, too. In other words, relative font size is preserved in the adjustments.

I'd just like to see a somewhat complete list here of elsewhere. --212.149.217.84 (talk) 18:14, 13 March 2008 (UTC)

I only know a little assembly but it seems like since the kernel is written in C and has a C interface, you'd need to use C :D\=< (talk) 18:38, 13 March 2008 (UTC)

This site will get you started. The basic idea is that you stick a syscall number from /usr/include/asm-i386/unistd.h into %eax, then put argument 1 in %ebx, argument 2 in %ecx, and so on. Do the int $0x80 to trap into the kernel, and get the return value out of %eax. E.g., to call time(), which is syscall #13, we do:

       movl    $13, %eax
       movl    $0, %ebx
       int     $0x80

Now %eax will contain the current unix time. As for glibc, that's just a normal user space library (albeit one that makes heavy use of system calls), and has nothing to do with them per se. --Sean 19:39, 13 March 2008 (UTC)

Simulating PowerPoint's increase/decrease font size features in OpenOffice.org Impress

In PowerPoint, you can select a block of text and adjust the font size (upward or downward) by clicking the "increase font size" or "decrease font size" buttons. These buttons increases/decreases the font size of the selected text to the next predefined font size in the "font size" dropdown list. If original font size is between two predefined font sizes, the adjusted font size will be between two (new) predefined font sizes, too. In other words, relative font size is preserved in the adjustments.

These functions are not available natively in OpenOffice.org Impress. Is there simple way to add these functions to Impress, perhaps by means of an extension or via OpenOffice.org Basic macros? --71.162.242.230 (talk) 16:21, 13 March 2008 (UTC)

Explorer.exe large Virtual Memory usage

Hello to all. All my problems started when I was writing a program in Python (PythonWim IDE), requesting it to store quite large bitmap in memory, and then write it to a file. In calculating what to put in its header as width and height, I divided wrongly by 16 instead of 256, and ended up with astronomically large width and height values (57000x12000). Upon attempting to view the file (from my desktop) in Paint, everything locked up, needing to be resolved by closing a few processes (including explorer.exe).

Upon restarting the explorer.exe process, it began with quite a small amount of virtual memory usage (5000 kB), then suddenly jumping to 600 000 kB and locking up. Of course, I tried a reboot, but it didn't work. The problem does not seem to occur on other accounts apart from mine (the only administrator account).

To try to solve it, I fired up WinDbg and chose Step over many times until finally reaching the point where memory usage darted up. It did so in two stages: first to 250 000 kB, then to 600 000 kB. The error seems to occur in the BrowseUI.dll module of the explorer.exe process. This is the output of !analyze -v:

It looks like what's happening is Windows is trying to process the file to give you a nice icon for it, but choking on the large file. I would try to get access to the disk somehow (boot into DOS or whatever kind of single-user mode equivalent Windows has, or do it from another account if possible), and go and delete the bad file. I'm always amazed at how hard and noisily Windows sucks! :) --Sean 19:47, 13 March 2008 (UTC)

Thank you, Sean. It is also amazing how the human mind seeks to solve problems in a much more complicated way then necessary. To think that I tried debugging the whole process before trying to delete the file. Indeed, your advice worked perfectly. Thank you once more. --Danielsavoiu (talk) 19:59, 13 March 2008 (UTC)

NFS Permission Problem

I have a fileserver. /home is owned by root:users and 777. Inside that is library owned by root:users and 777. Inside that is text files owned by root:users and 666. All users are in group users. I NFS mount /home/library. On the fileserver, exports is using rw,no_root_squash,async. On the local computer, it mounts as nfs rw. I ensured all user and group IDs are the same between both machines. I can read files fine. When I try to save a file, it deletes the contents of the file and then complains that the local user doesn't have rights to save the file. If I change the owner of the file to the local user, I can open and save without problems. I need for all members of group users to be able to read/write the files. I really need to stop the current experience of clicking "save" and having it delete the contents of the file and then throw a permission error. Is there something obvious that I am missing? -- kainaw™ 18:41, 13 March 2008 (UTC)

rip

can one rip clips from you tubb and save them to his pc? —Preceding unsigned comment added by 41.220.113.117 (talk) 02:13, 14 March 2008 (UTC)

Yes! However, YouTube compresses files in a flash video (flv) format to save on storage space and download time. One can use Mozilla Firefox (aren't you excited about Firefox 3?) and add an addon like download helper to download the video. Then, one can use a media player like VLC media player to play the video.

Cheers,

Kushal 02:30, 14 March 2008 (UTC)

Yep and if you don't want to download an addon you can use a web based tool to determine the actual URL of the FLV file. You still need to install VLC though :D\=< (talk) 03:01, 14 March 2008 (UTC)

There are some tools out there that will let you transcode the FLV into other formats. Vixy.net can do this though I've sometimes had problems getting it to work. If you convert it to AVI or MOV then you don't need VLC (you can use Windows Media Player to play AVI files if you use Windows, or Quicktime Player to view MOV files). (Can you tell I don't like VLC much? I find it just a wee bit too buggy for anything other than emergency use. It has a habit of crashing on me or just not doing what I tell it to do.) --98.217.18.109 (talk) 03:14, 14 March 2008 (UTC)

The video is compressed with H.263 or H.264- transcoding would just result in loss of information. :D\=< (talk) 03:55, 14 March 2008 (UTC)

Yes and no. Yes, you lose information, no, that's not "just" what would result. Part of the result is having it in a format you can do other things with. Which can be important too. Especially if VLC crashes when seeking FLVs (which it usually does for me), which makes it pretty useless in this scenario. --98.217.18.109 (talk) 12:31, 14 March 2008 (UTC)

I personally use DownloadYouTubeVideos to get the .flv files and Riva FLV, which comes with an encoder and player. crassic!^[talk] 03:34, 14 March 2008 (UTC)

Segfault hunting

How does one trap a segmentation fault? The OS is managing memory; how does the processor know to switch back to the kernel when it encounters a segfault? I can't imagine that the OS can be like checking each instruction before it's executed; if you tried to check what's in the register you're jmping to, you'd have to context switch every instruction to actually have registers to work with in the checking code, which would just be insane so it has to be built into the processor somehow-- but how does it even know? :D\=< (talk) 02:59, 14 March 2008 (UTC)

See protected mode. The operating system makes programs run in protected mode. If they try to reference memory outside of their alligned space, the CPU itself detects that the address is out side of an allowed segment range and an exception occurs, which the OS handles. It is a hardware thing. You cannot have a segment fault on CPU's that don't have protected type modes. Many microprocessors in embedded electronics for example have no such thing as real/protected mode and its impossible to detect and stop a segment fault. —Preceding unsigned comment added by 155.144.251.120 (talk) 03:41, 14 March 2008 (UTC)

It's not really protected mode per-se, but the presence of hardware memory mapping - indeed one can get get memory violations in kernel mode (see note at the end). The availability of a protected-memory userspace model is a consequence of there being memory management hardware. Froth: any memory access (read, write, execute) is actioned by the CPU via the hardware Memory management unit, which generally maintains a cache (the TLB) of segments (I hesitate to call them "pages", because depending on the architecture they're single pages or contiguous runs of pages) of memory that are mapped. On full-featured CPUs (not weird stuff or embedded) each entry in the TLB has permissions bits (can read, can write, can exec). When actioning a memory access, the MMU looks the requested address and action up in the TLB - if there isn't a mapping, or if the requested action isn't permitted, then the MMU throws an exception. Most of the time you don't actually see this as a SIGSEGV in your program, because this same mechanism is exactly how the paged-memory system works - most of the time the OS intercepts the exception, uses that information to load/unload virtual memory pages between disk and ram, twiddles the TLB accordinly, and then clears the exception - the new TLB entry allows your request to proceed and all is well. You only see a SIGSEGV when the OS can't figure out a way to meaningfully satisy your request - when you're addressing memory for which the OS's own tables don't have a valid virtual page to swap in - so the OS chucks a SIGSEGV up to the usermode program.

The reasons kernel-space programs can still hit page faults is the entire physical address space isn't entirely filled with mapped RAM, ROM, Flash etc chips - only certain areas are, for which the MMU has a (generally fixed, sometimes hardwired) mapping to actual chip selects - so (depending on the architecture) if kernel space code tries to access physical memory that has no valid CS mapping the MMU will barf at it. -- Finlay McWalter | Talk 13:23, 14 March 2008 (UTC)

If you want the ultimate low-level knowledge, see "AMD64 Architecture Programmer's Manual Volume 2: System Programming" here. It also includes the 32-bit x86 things. --ÖhmMan (talk) 14:07, 14 March 2008 (UTC)

Actually "the MMU maintains the TLB" is misleading - the TLB presents a bunch of memory-mapped registers inside the MMU (or somewhere in physical memory that's read by the MMU, depending on architecture) but their contents are largely maintained by the memory-management part of the OS. -- Finlay McWalter | Talk 14:35, 14 March 2008 (UTC)

Some good things to read to understand this stuff without wading through CPU manuals are the memory-management bits of Understanding the Linux Kernel, and especially the excellent Unix Systems for Modern Architectures. --Sean 15:33, 14 March 2008 (UTC)

Overclocking CPU multiplier

Hi. Is it in general possible to increase a CPU's clock multiplier (not FSB) above its factory setting? With my current ASUS P5B-V board and Intel E4500 CPU, I seem to only be able to decrease it. Will it be possible, say, with an ASUS Maximus Formula and Intel E8400? Thanks. -- Meni Rosenfeld (talk) 10:32, 14 March 2008 (UTC)

I know some CPU's multipliers are unlocked in the BIOS, but some are locked. Mine (AMD FX-60) is unlocked, but I haven't ever messed with it, so I don't really know the best procedures for overclocking. Useight (talk) 15:26, 14 March 2008 (UTC)

Erm I'm not very expert on these things and never have tried myself - but - I understand that the clock multiplier is a hardware thing - so if you've got say a 10 or 11x multiplier it's impossible to go higher since the circuitry isn't there.? That may all be wrong..

have you tried downloading a different BIOS - eg have you got this one ASUS P5B-V BIOS 0804 87.102.83.204 (talk) 16:20, 14 March 2008 (UTC)

bash here-document

In bash, how do I make cat watch for a here document which is actually me pressing enter 3 times?

I want to do something like

cat << $(echo -e \\n\\n\\n)

But the above doesn't work. Any ideas?

Thanks --194.223.156.1 (talk) 12:05, 14 March 2008 (UTC)

cat is used to concatenate text (usually) files together. It doesn't "watch" for things. Also, what is a "here" document? The keyboard is considered a stream, not a file, and is normally called "standard in" or "stdin" for short. It appears you are trying to hit enter three times and have it appear on the screen. What do you want to happen after that? Do you want it to stop and go back to the command prompt? -- kainaw™ 12:29, 14 March 2008 (UTC)

A "here document" is a bash trick whereby one can create a tmp file inline, without creating one explicitly - that's what the << thing does. So one can say sort << FOO and then (at the > prompts that appear) type obama(return) then mccain(return) then clinton(return) then FOO(return) and it'll print those three names sorted. The OP wants this sequence to stop on an explicit three empty lines (rather than an explicit delimiter like FOO). I don't know how to do that - you can get it to stop on a single empty line with sort << "" -- Finlay McWalter | Talk 12:38, 14 March 2008 (UTC)

Cool. I've never used cat for that. When I want code before/after a delimiter (even when sending it from the console), I tend to use grep. -- kainaw™ 13:05, 14 March 2008 (UTC)

It's not particularly for cat, and I think the OP's use of cat may just have been for illustrative purposes. A here-document is particularly useful for single-file installers, config scripts, and self-extracting archives, where you can have multiple final files (or things that, after processing, will become individual files) all nicey stored and pleasantly formatted inside a single master bash script. -- Finlay McWalter | Talk 13:40, 14 March 2008 (UTC)

This isn't bad: here document. --Sean 15:36, 14 March 2008 (UTC)

On looking at the relevant section of the bash manual it doesn't look like what you ask for is possible. It looks like the code for here documents works something like:

     forever:
       x = read a line (probably using fgets or the like)
       if x==theDelimiter: quit
       do stuff on x

so it's line by line - three carriage returns in the here document cause three seperate trips through the loop body (because fgets uses \n to split lines), so you'll never get a match. I can't think of a clever way to overcome this. <snarky comment>if you'd done this in perl or python you'd be sipping pina coladas with Natalie Portman by now :)</snarky comment>-- Finlay McWalter | Talk 12:54, 14 March 2008 (UTC)

Yep, thinking about it that seems likely, unfortunately. To answer Kainaw: I was mostly using cat for illustrative purposes but in fact my script does use it (although of course it's then piped off somewhere else). I don't want users (well, me) to have to do Ctrl-D in this particular context. Thanks to all anyway. —Preceding unsigned comment added by 194.223.156.1 (talk) 13:51, 14 March 2008 (UTC)
