Occasional surround sound support via laptop HDMI out

I have an Asus M50Sv laptop with HDMI out. I'll play some movies from media player with surround sound just fine, but for some reason I only get stereo while playing Half-Life 2. I checked the HL2 settings and it's set to 5.1 on the audio tab.

I checked the Vista (Home Ultimate) sound settings and they show only LR channels for the HDMI output (and the same for what I assume is the SPDIF output) in the sound settings, but I figured this was more of an audio encoding thing (a la Dolby Pro Logic), but got confused when I could only get stereo in HL2. Then I played a movie in WMP11 and got all the channels just fine.

Is the game too old? (2004) Is there something I can change to get full surround? I'd hate to have to connect another cable, because it's just so painfully convenient to have a single HDMI cable hooked up to my TV to get a glorified gaming console for 4x the price :).

Thanks! --156.34.78.224 (talk) 02:10, 10 August 2008 (UTC)

Line breaks on gmail

Is there any way to change the number of characters for the line break on gmail? My lines are insanely short, and I can't figure out for the life of me how to change it. Magog the Ogre (talk) 05:26, 10 August 2008 (UTC)

Could just expanding your window work? Are these line breaks being sent as well, or are they only display issues when composing mail? --omnipotence407 (talk) 11:38, 10 August 2008 (UTC)

Do you mean the point where plain text mails are wrapped with a > sign? Kushal (talk) 14:16, 10 August 2008 (UTC)

I had a similar problem a while back where for a short time suddenly all the emails I sent were arriving with each paragraph put on one single line going right off the page. People had to scroll along to read each paragraph then scroll back for the next one. I kept getting emails back from friends saying reading my emails was a pain in the arse and I couldn't figure out for the life of me why. It fixed itself, somehow. I have no idea what happened. Your problem might just be a temporary thing, too.--ChokinBako (talk) 00:23, 12 August 2008 (UTC)

This problem almost certainly stems from ambiguity about who/what is putting the line-break characters in (i.e. are you hitting enter at the end of each line, or do you just let the input-text-box do the wrapping automatically?). Some text display systems use line wrapping even when there is no actual line-break character in the text stream. If text was written or displayed on such a system, and then transferred to some other program which does not intelligently interpret the presence or lack of newline characters, formatting nightmare will ensue. Nimur (talk) 16:57, 13 August 2008 (UTC)

Ye, the problem is that the text is line wrapping too early when I send it. It's a pain to read, and I don't like it. I want to change it. Magog the Ogre (talk) 02:41, 17 August 2008 (UTC)

bash for

I need to do a lot of things (using sed, mostly) to quite a a lot of files. But when I check that I understand for in bash, I'm embarrassed to find that I don't.

As a minimalized example, let's suppose that I want to automate the renaming of two files: from a.txt to a2.txt, and from b.txt to b2.txt. I'd have thought that bash would do this via something along the lines of

    for firstpart in [a b]
    do
        mv $firstpart.txt $firstpart2.txt
    done

However, this doesn't work, and no variation on it that I've yet thought of does it. I've found various guides to flow control within bash (or Bourne), but curiously none seems to deal either with lists that one has just made up or with the manipulation of filenames. What am I missing? -- Hoary (talk) 07:11, 10 August 2008 (UTC)

Your 2 bugs are: the brackets around a and b, not helping. Get rid of them. Second, "$firstpart2" is the value of the variable named "firstpart2". You need to use ${firstpart}2 to get what you wanted: the value of the variable named "firstpart", then a "2". Braces around the variable name are needed whenever it is immediately followed by some text that might be part of the variable to be expanded. (Imagine you also had f=this and firstp=that then what would you expect $firstpart to expand to? It wouldn't be "thisirstpart" or "thatart".) --tcsetattr (talk / contribs) 08:42, 10 August 2008 (UTC)

Excellent! Thank you very much. But stick around, please, because I have an even stupider question. Though I have successfully written and used very elementary shell scripts under GNU/Linux/bash, today I'm using Mac OSX. This claims to have the bash shell, so I hadn't thought Mac OSX would be an issue; however, it seems that I can't get any shell script to run. The simplest: a text file consisting of the single line/command:

ls

I save it with the name "sillyscript" and type

chmod +x sillyscript

I check with

ls -l

and sure enough, yes, it's executable (so at least I didn't manage to screw up chmod). I then type

./sillyscript

and get the helpful message from bash: Cannot execute binary file. Actually I don't even understand what this "binary file" is, as sillyscript isn't binary (except in the sense that anything in a computer is binary), and as far as I know ls isn't a file. As we hopeless beginners say, WtF? -- Hoary (talk) 09:13, 10 August 2008 (UTC)

OK.

for I in *.txt ; do mv $I `basename $I .txt`2.txt ; done

You need to make the file begin with shabang. shebang.

#!/bin/bash
ls

--Kjoonlee 09:41, 10 August 2008 (UTC)

How odd. But many thanks! -- Hoary (talk) 10:10, 10 August 2008 (UTC)

Except that it doesn't work. I even checked that yes, bash really was in /bin, and of course it is. I added the shebang line exactly above, and saved, yet I am still told:

-bash: ./sillyshell: cannot execute binary file

Er. . . . -- Hoary (talk) 11:07, 10 August 2008 (UTC)

What does

file sillyscript

say about it? Does bash ./sillyscript work? What editor / thing are you using to edit the file? --78.86.164.115 (talk) 13:31, 10 August 2008 (UTC)

file sillyscript

tells me

sillyscript: UTF-8 Unicode text

while

bash ./sillyscript work

tells me

./sillyscript: ./sillyscript: cannot execute binary file

The little script was made with TextWrangler.

I'm going to sleep on this. If I can't do it easily tomorrow (my time), I'll give up with it and do it on my Linux machine (an hour's trainride away). Still, I'm fascinated as well as irritated by my inability to do something (run a script) with an all-singing, all-dancing Mac that I used to do on a CP/M-80 machine with 64kB (yes!) of RAM. Something's gone off (maybe just my brain). -- Hoary (talk) 15:19, 10 August 2008 (UTC)

Hm, what happens if you do this?

cat > sillyscript2
#!/bin/bash
ls
[press ctrl-d]
chmod u+x ./sillyscript2
./sillyscript2

--Kjoonlee 15:32, 10 August 2008 (UTC)

That worked perfectly! Well, it's one way to write text files, I suppose.

I'm afraid I've forgotten if there's a GNU/Unix utility that reads two files and announces if they have the same checksum; therefore I don't know for sure that these two minuscule scripts are identical. But for what it's worth (I'm sleepy), the two files do look identical. The obvious difference is that sillyscript and sillyscript2 are -rwxr-xr-x and -rwx--r-- respectively. I've no idea why this difference should matter. (Unless the shell for Mac OS X is somehow tweaked to render non-executable any script that's supposed to be executable for everyone, maybe because such ease of use makes it smell Trojan. No, that's too silly.) -- Hoary (talk) 16:01, 10 August 2008 (UTC)

My guess is that TextWrangler is putting a Unicode byte-order mark at the beginning of the file. Look for an option that turns this off, or save as ASCII. -- BenRG (talk) 17:25, 10 August 2008 (UTC)

The utility that you want is cmp, although diff might also work (depending on what it makes of things like the putative BOM). I would expect either system you named to have both utilities. --Tardis (talk) 14:28, 11 August 2008 (UTC)

Switching keyboards

I have a laptop (running Windows Vista) with a UK format keyboard, but I often use an external US format keyboard. Consequently, I have the language toolbar set up to allow me to switch from one to the other. However, something that has bugged me for a long time is that the keyboard setting seems to switch spontaneously. Anyhow, today I found out that I can switch keyboards by pressing left-shift and left-ctrl together and that would explain the "spontaneous" switching - I'm not a good typist and I'm obviously hitting shift and ctrl. Is there a way to turn off this key combination, or change it to something that's less easy to hit by mistake? Astronaut (talk) 16:09, 10 August 2008 (UTC)

Windows (XP anyway) is really brilliant at switching layouts, because it lets you use as many different keyboards on different programs all at the same time. For example, you can put Microsoft Word on UK and Firefox on US - all at the same time! Have you tried setting a different shortcut, which you can't press by accident? Maybe "Control Shift Alt Zero".78.144.189.229 (talk) 16:34, 10 August 2008 (UTC)

How do I set a different shortcut? Astronaut (talk) 16:36, 10 August 2008 (UTC)

I won't bash you for using Windows :-) But neither Mac OSX, or Unix systems in general, seem to do that. The other possibility is that it switches automatically according to whether you use the built in, or external keyboard. Now that, I can at least see the logic in - even if it is annoying. As for keyboard shortcuts, I only have XP, but I will go and check.78.144.189.229 (talk) 16:38, 10 August 2008 (UTC)

I get Control Panel>Regional and Language (in classic view)>Languages>Details>[Select the keyboard layout you want]>Key Settings>Change Key settings.78.144.189.229 (talk) 16:49, 10 August 2008 (UTC)

I would expect it to switch to US format whenever the external keyboard is plugged in (my old work laptop on XP did just that), but it doesn't. Anyway, I found the setting and I can now type as bad as I like without it spontaneously switching on me.

However, it's slightly different in Vista from your instructions. It goes like this: Control Panel -> Regional and Language Options -> Keyboard and languages tab, and click on the Change Keyboards button; then on the Advanced Key Settings tab, make sure the "Between input languages" is selected and click the Change Key Sequence button. There, you will find the settings for the Alt-Shift sequence to change language and the hidden ctrl-shift sequence to change the keyboard layout.

Thanks for your help 78.144.

GPL terms

If a program is released under GPL, would it be legal/OK for someone to modify the program directly, then distribute it as his or her own? What about if it were distributed for money? For free? --99.175.89.127 (talk) 03:10, 11 August 2008 (UTC)

You're lucky you edited your question when you did; you caught me in an edit conflict. A quick look over the GPL page seems to say that you could modify the program and use it commercially. However, I do believe you have to share alike (publish under the GPL or another compatible license). Of course, IANAL, and my experience in GPL is limited to reading the article. Paragon¹²³²¹ 03:30, 11 August 2008 (UTC)

Yes, you can certainly modify GPL software and sell the result for money; it's encouraged. But the license requires you to make the full source code of your version available and license it under the GPL. This means, in particular, that anyone who buys your version is free to make copies of it and redistribute them for free. -- BenRG (talk) 10:49, 11 August 2008 (UTC)

You can't redistribute someone else's GPL'd code as your own. You can use it, you can charge for it, you can modify it, but you have to acknowledge that some portions of the code are someone else's. 24.76.161.28 (talk) 07:30, 14 August 2008 (UTC)

3G phones running J2ME

I am looking to get a 3G phone that runs J2ME. (Actually, I might be open to Windows Mobile OS, except for my generally low opinion of Microsoft products. Is Windows Mobile OS as good as J2ME?) I am in the United States, so the phone has to be supported by a US telecoms company with a 3G network. However, I also want to be able to use the phone in other countries, such as Canada and the UK, so I'd like to be able to replace the SIM card with a prepaid card purchased in the country where I will be using the phone (to avoid high roaming charges from my US provider). Can anyone recommend phones (and telecom providers) that meet my criteria? Thank you. Marco polo (talk) 16:41, 11 August 2008 (UTC)

tagging or categorizing files under Windows

I would like a method that I can use to apply multiple tags or categories to files on my computer. I need to able to mark any file with more than one category, much like a wikipedia article, for the purposes of finding and organizing info in many different file formats. Any ideas? ike9898 (talk) 17:28, 11 August 2008 (UTC)

Nothing built into Windows will let you do this (that I'm aware of...). I'll do some searching for third-party software and get back to you. ---J.S (T/C/WRE) 22:59, 11 August 2008 (UTC)

Here are some ideas that may be totally inappropriate for your needs:

• Dump all the files in one folder and put the tags in the filenames (perhaps surrounded by square or curly brackets), then use Explorer's search feature or command-line wildcards to find files with a particular tag or group of tags. It sounds silly but may be the most convenient option.
• Create a directory for each tag and use hard links to put the same file in more than one directory. This shell extension might be helpful.

-- BenRG (talk) 23:14, 11 August 2008 (UTC)

I can't find anything better. I know Google desktop offers a very good search tool for your home computer. It even lets you search the contents of documents. Maybe that would be of help? Otherwise, you might just use a "tree" approach with sub-folders and whatnot. ---J.S (T/C/WRE) 00:27, 12 August 2008 (UTC)

The big problem with the "tree" is that I can't put the same file on two branches at once. Well I could put separate copies on separate branches, but that doesn't really work for my purposes. I need to be able to modify the files, and having multiple copies would make it difficult to maintain. ike9898 (talk) 17:15, 12 August 2008 (UTC)

You could run MediaWiki on your computer, and use it to link to files located (where-ever) - on your local PC, on the intra-net, inter-net, etc... The actual file locations wouldn't reflect your categorization scheme. This will separate content from meta-information, and also allow you to use the familiar mediawiki interface and built-in Categories utilities. Nimur (talk) 17:08, 13 August 2008 (UTC)

I considered that once. What I learned about setting up MediaWiki on a personal PC made it seem like a daunting task. Do you have any opinion on how difficult this would be? ike9898 (talk) 19:19, 13 August 2008 (UTC)

I have set up MediaWiki on many computers, including "desktop"/"laptop" workstations running Windows. There are helpful instructions, such as the official manual, and you can check the internet as well. Depending on your technical savvy, you can take a lot of shortcuts/variations, or you can blindly follow the instruction manual. It is a worthwhile exercise; you may find a private MediaWiki with its built-in history, searching/categorization, etc, useful for a variety of tasks from leaving yourself notes to writing and versioning your homework assignments. Nimur (talk) 21:37, 13 August 2008 (UTC)

There is something like this in Windows XP, at least, in Windows XP Professional. The "Keywords" in the Summary pane of the properties of a file is supposed to work like this. I believe Windows 2000 had it, and I'm pretty sure Windows 2003 has it, too. Of course, off the bat, I don't know of anything besides Windows Explorer's normal view that can really use this information. Even Find/Search doesn't seem to know about it. It's implemented using Alternate Data Streams (ADS) on NTFS systems, so Streams from the Sysinternals Suite would be able to tell you some information about files tagged this way. jdstroy (talk) 23:30, 18 August 2008 (UTC)

Interpreting MIDI (SMF) Delta Time Values

I am trying to write a MIDI (SMF) Media Player, but is somewhat confused about the delta time values found in SMF's. As I understand it, these values are given in a unit called "tics", and in the MIDI File Header one can read the number of tics per another unit, called "beat" or "quarter note" (is 1 beat = 1 quarter note?). Moreover, reading a Meta Event, one obtains a quantity with the dimension of microseconds per beat, and consequently, I thought,

IntervalInMilliseconds = MicrosecondsPerBeat * IntervalInTicks / TicksPerBeat.

Is this the correct formula to use, or must I - for instance - also consider the so-called "time signature" of the music? --Andreas Rejbrand (talk) 22:13, 11 August 2008 (UTC)

Your formula correctly calculates the interval in microseconds (not milliseconds) from a certain interval in ticks, assuming there's only one tempo for the entire interval.

Yes, I forgot a factor of 10³ (which is present in my code). --Andreas Rejbrand (talk) 17:04, 12 August 2008 (UTC)

The Tempo meta event (which specifies the tempo in terms of microseconds per quarter note) can be used multiple times to change the tempo of playback, so the actual duration of a tick can change depending on the most recent Tempo meta event.

The Time Signature meta event is used to group the beats into measures, but doesn't affect the duration of a tick. --Bavi H (talk) 01:40, 12 August 2008 (UTC)

Something taking up a bunch of space on my harddrive

I just got a brand new laptop, it's a Sony Vaio with Vista Home Premium. I don't use it much and have added nothing to it besides a few programs. I've noticed something peculiar though: my amount of free space drops about a GB every day and has been doing so for a week or two, despite the fact that in that time I have not added even one file. To the right is an image I just made. On the left: I double clicked my harddrive > select all > right click > properties. On the right: right click harddrive > properties. In Folder Options, it says I have it set to view hidden files. I go to Disk Cleanup and even with every option selected, it can only free up about 3GB of space. A friend suggested that maybe my page file is increasing every day. What's taking up all this space? Thanks for your help. NIRVANA2764 (talk) 22:41, 11 August 2008 (UTC)

Even with "show hidden files and folders" selected Explorer may not show everything; at least on XP you have to also uncheck "hide protected operating system files". Among the protected operating system files are \RECYCLER (Recycle Bin) and \System Volume Information (System Restore), either of which could be taking up lots of space. -- BenRG (talk) 23:25, 11 August 2008 (UTC)

This tool, called WinDirStat, is great for "visualizing" where your disk space has gone. ---J.S (T/C/WRE) 00:31, 12 August 2008 (UTC)

It must be the \System Volume Information folder (where System Restore saves its restore points). The folder typically is only accessible by the system, and that's why if you have the display of hidden and system files on, it may not show the true size of the folder. That is the only thing I can think of that might be grabbing your disk space continuously. And it turned out you cannot purge the restore points with Disk Cleanup tool in Vista; you can limit the amount of disk space it is using though.  ARTYOM  03:20, 12 August 2008 (UTC)

J.smith, you recommended WinDirStat. I downloaded it, and it says a completely different number than my Local Disk (C:) Properties window does.

Is a PCI adapter the same as a network adapter?

I have been advised that the network adapter in my desktop PC is dead, and I would like to replace it myself. I cannot connect to my DSL connection through the desktop PC, and it will not allow my laptop to establish a wireless network connection either. I need to know what to look for at the store.

What's happening with my mouse?

On my iBook, if I put one finger on my mousepad and then move another finger over it extremely closely (but not actually touching), the pointer moves (erraticaly), even though the moving finger is not actually touching it.

Odd output of a C++ program

So, I have been dabbling in C++ a bit lately and have written a program to check if one number is wholly divisible by another. Here is the source code:

#include <cstdlib>
#include <iostream>
using namespace std;
int main()
{
   system("title Divisibility Check");
   for( int x = 1; x < 2; x)
   
   {
        float a;
        int b;
        int m;
        cout << "Check to see if a is divisible by b." << endl;
        cout << "Please enter a." << endl;
        cin >> a;
        cout << "Please enter b." << endl;
        cin >> m;
        b = int(a)/m;
        
        if ( a/m != b)
        {
             cout << endl << a << " is not divisible by " << m << "." << endl << endl;
        }
        
        else if ( b = a/m )
        {
             cout << endl << a << " is divisible by " << m << "." << endl << endl;
        }
        else
        {
             cout << "Sorry, that input is not valid." << endl;
        }
   }
   system("pause");
   return 0;
}

After compilation, when the program is run, this is what it says:

Check to see if a is divisible by b.
Please enter a.
<Then you enter a number here.>
Please enter b.
<Then you enter another number here.>

If I enter anything other than a number, the program freaks out and starts to reiterate the previous output in an infinite loop. I realize that a letter is not of type float or int, but why will this not just direct the program to the else loop? How can I fix this behavior? Thanks, Ζρς ι'β' ^¡hábleme! 02:15, 12 August 2008 (UTC)

for( int x = 1; x < 2; x)

Should this perhaps be "for( int x = 1; x < 2; x++)"? Otherwise the condition x < 2 will always be true. Gyroggearloose (talk) 02:31, 12 August 2008 (UTC)

No, I want it to be perpetually true. This way, multiple divisibility checks can be preformed without repeatedly restarting the program. If I wanted it only to run once, I would omit the for loop entirely. Ζρς ι'β' ^¡hábleme! 02:39, 12 August 2008 (UTC)

What you are seeing is normal. It is a bad practice to scan the input buffer and expect it to be a number. To be general to the point of not being exactly correct... you have something like "10\n" in the input buffer. The \n signifies that you hit the enter key. You ask for a number. You get a 10 and it clears the trailing enter key. Now, you do it again with "hello\n". It doesn't see a number, so it leaves the buffer there. Then, it looks again. No number still. It looks again. Still no number. It looks again. Still no number. If this was a buffer that changed over time, it may turn into a number at some point, but the keyboard buffer doesn't change until you flush it in some way.

OK - that is a pain. What are you supposed to do? Make a temporary string/char* variable. Scan the input into that variable. Then convert the string to a number (if possible) or tell the user that the number keys are above the letter keys. -- kainaw™ 02:50, 12 August 2008 (UTC)

Ahh, too true. I looked at it too early in the morning I guess :)

BTW, "else if ( b = a/m )" should probably be "else if ( b == a/m )" or else b gets assigned the result of a/m instead of being compared to it. Gyroggearloose (talk) 03:05, 12 August 2008 (UTC)

There are also the iostream ignore() methods, which allow you to clear the "keyboard" buffer if it contains things that you don't want. It's a shame that these routines are not usually included early on in courses or books on the subject; in my early C++ programs I knew only how to abort the program whenever something bad was entered! You can test whether something bad was entered with if(!cin) /*...*/; I exited the program there, but you can use ignore() instead. --Tardis (talk) 15:33, 12 August 2008 (UTC)

If you want something to loop forever, just say while(true) /*...*/. And if you really want a for loop, you can leave out expressions entirely and write for(int x=1;x<2;) or even for(int x=1;;). --Tardis (talk) 15:35, 12 August 2008 (UTC)

Or, you can be super cool with something like: define forever=true; and then in your code use for(ever;;).... -- kainaw™ 15:40, 12 August 2008 (UTC)

Well, hang on anyway. Even with the typo corrected, look at this:

        if ( b != a/m)
        {
             action1;
        }
        
        else if ( b == a/m )
        {
             action2;
        }
        else
        {
             action3;
        }

There's no way action3 gets executed. Either b != a/m or b == a/m; there's not a third choice. (See law of the excluded middle.) If you get to that first "else", you know for certain that b == a/m. --jpgordon^∇∆∇∆ 03:17, 12 August 2008 (UTC)

Surprisingly, in some contexts (though I doubt it here) it would be possible for the third branch to be taken; for instance, IEEE extended precision can cause a conditional to have one value and then invisibly change to another value when one of the operands got rounded down to double precision. Not to mention things like NaN… --Tardis (talk) 15:33, 12 August 2008 (UTC)

It's not your question, but your variable types and names and logic are somewhere between iffy and wrong. You prompt for b and then read in m, which just confuses the reader. You read a as a float, but then calculate b from int(a); I suppose it's true that no non-integer is divisible by any integer, but it's still bizarre. Finally, although I haven't found a counterexample for operations this simple, it's in general a bad idea to test for equality with floating-point numbers; for example, often 0.1*0.1!=0.01. (See also my above comment about surprises in floating-point comparisons.) What you want is just integers and the modulo operation. --Tardis (talk) 15:33, 12 August 2008 (UTC)

One minor point : You picked a very confusing way to do a while(true) loop. Using a for loop where you intend an infinite loop makes it look as though you've made an error. APL (talk) 15:20, 12 August 2008 (UTC)

Ok, upon all of your suggestions I have refined my program.

#include <cstdlib>
#include <iostream>
using namespace std;
int main()
{
   system("title Divisibility Check");
   while(true)
   
   {
        int a;
        int b;
        cout << "Check to see if a is divisible by b." << endl;
        cout << "Please enter a." << endl;
        cin >> a;
        cout << "Please enter b." << endl;
        cin >> b;
        
        if ( a % b != 0 )
        {
             cout << endl << a << " is not divisible by " << b << "." << endl << endl;
        }
        
        else if ( a % b == 0 )
        {
             cout << endl << a << " is divisible by " << b << "." << endl << endl;
        }
        else
        {
             cout << "Sorry, that input is not valid." << endl;
        }
   }
   system("pause");
   return 0;
}

Is there anything that should be changed about this one? Thanks, Ζρς ι'β' ^¡hábleme! 18:51, 12 August 2008 (UTC)

Yeah. There's no way for the "Sorry that input is not valid" branch to be taken. As above, either (a % b == 0), or (a % b != 0). There's no third choice. And this version will still loop forever on invalid input. cin >> a won't change the value of a if the input isn't an integer; you need to add some error checking. You might say:

      cin >> a;
      if (cin.fail())
      {
         cout << "Sorry, lousy input; enter an integer." << endl;
         continue;
      }

I'm not sure why the system("pause") is there, either. --jpgordon^∇∆∇∆ 21:06, 12 August 2008 (UTC)

Capturing MiniDV tapes to a PC

Hello. I am trying to capture my MiniDV tapes to my computer, with the purpose of burning them to a DVD later. I do not want to reduce the quality while capturing, and just capture the whole thing in AVI format. I have heard that the best way to do that is to split the video into pieces, 10 minutes or so each, to avoid one huge one-hour video file weighing about 12 GB. I tried using Pinnacle Studio for this, but it turned out to do a pretty horrible job. When I try to capture the tape by 10-minute fragments (i.e. tell it to stop capturing after 10 minutes), it loses a couple of seconds between the pieces: after one piece is saved and I start capturing the next 10-minute piece, the video starts playing and the capturing begins with a 2-second or so delay. Besides, the video files are not exactly 10 minutes, but are 2-3 seconds over.

Windows Movie Maker seems to be able to do the capturing, but I couldn't find an option to split the output into several pieces, and I don't really think WMM would do a better job than Pinnacle.

Anyway, I was wondering what other program I can use to do the capturing the best way? Thanks,  ARTYOM  03:11, 12 August 2008 (UTC)

Would'nt it be easier capturing that one (12 or so GB) file, and then cutting it to pieces? (It would require disk space). -Yyy (talk) 10:57, 12 August 2008 (UTC)

Yes, but wouldn't it require more computer performance to capture the whole tape at once? That's what happened to Pinnacle - it just stopped capturing about halfway through the tape and froze. It only unfroze when the tape ended, and it turned out that nothing was captured when Pinnacle was "frozen".

P.S. I have quite a powerful computer, so that shouldn't be the case.  ARTYOM  17:13, 12 August 2008 (UTC)

If you're using Microsoft Access, you would use a crosstab query, making "Name" the row heading (under "Crosstab", in Access 2007) and "Food" the column heading. Add either column to the query again and make it the "Value", and change the "Total" field to "Count". Among database environments the ease of producing a crosstab will vary considerably; you may have to use programming or trick layers of SQL statements into doing it. For MySQL, for example, I found stuff like [3] and [4]. But in Access it's easy. Whiskeydog (talk) 04:31, 12 August 2008 (UTC)

You can get one column using "select Name, count(*) as Bread from tblLunch where Food='bread' group by Name". You can get another column with "select Name, count(*) as Apple from tblLunch where Food='Apple' group by Name". Now, if joined those two, you would get "select Name, Bread, Apple from (select Name, count(*) as Bread from tblLunch where Food='bread' group by Name) a join (select Name, count(*) as Apple from tblLunch where Food='Apple' group by Name) b on a.Name=b.Name". Expand that to every column you need. -- kainaw™ 15:22, 12 August 2008 (UTC)

This is for Microsoft Access:

SELECT tblLunchOrder.Name, SUM(IIF(tblLunchOrder!Food="Apple",1,0)) AS Apple, SUM(IIF(tblLunchOrder!Food="Beer",1,0)) AS Beer, SUM(IIF(tblLunchOrder!Food="Bread",1,0)) AS Bread, SUM(IIF(tblLunchOrder!Food="Steak",1,0)) AS Steak FROM tblLunchOrder GROUP BY tblLunchOrder.Name;

This is for MySQL:

SELECT tblLunchOrder.Name, SUM(IF(tblLunchOrder.Food="Apple",1,0)) AS Apple, SUM(IF(tblLunchOrder.Food="Beer",1,0)) AS Beer, SUM(IF(tblLunchOrder.Food="Bread",1,0)) AS Bread, SUM(IF(tblLunchOrder.Food="Steak",1,0)) AS Steak FROM tblLunchOrder GROUP BY tblLunchOrder.Name;

I wonder why you have to use "IIF" in Access. If you're working on a complex project, this could kill you. -- Toytoy (talk) 23:29, 12 August 2008 (UTC)

You should definitely use the cross-tab query if you are doing it in Access. IIF is extremely slow. --98.217.8.46 (talk) 14:55, 13 August 2008 (UTC)

Firefox 3 for Mac: tabs keep losing focus

My copy of Firefox 3 for Mac is acting up; every so often, tabs keep losing focus when I switch between them using the keyboard (Cmd-Shift-[ & Cmd-Shift-])—the computer will "beep" and refuse to cycle through the tabs further. I have to either click on another tab or press Ctrl-Tab to cycle through tabs properly again.

CPU

What are the advantages and disadvantages of having a 64 bit CPU (such as the Turion 64 which is built with the x86-64 instruction set) which is able to execute the x86 instruction set as compared to having a 32 bit x86 CPU? How will speed and compatibility vary? Thanks, Ζρς ι'β' ^¡hábleme! 19:04, 12 August 2008 (UTC)

See 64-bit#32 vs 64_bit. -- kainaw™ 19:15, 12 August 2008 (UTC)

That whole section looks like a mess of unsourced opinion and original research to me. I'm inclined to delete most or all of it. Here's my own unsourced opinion and original research: there's no disadvantage (aside from price) to getting an x86-64 CPU, since it will run x86 software just fine. If you actually want to use the 64-bit features you'll have to switch to a 64-bit OS, which will involve the usual OS-switching headaches. A 64-bit version of a program may be faster or slower than a 32-bit version. Going from 32 bits to 64 bits tends to make things slower, because all those 64-bit pointers have to be stored somewhere and RAM doesn't suddenly double in speed. However x86-64 has far more CPU registers than x86, which I think significantly improves performance. (This has nothing to do with being 64-bit as such, it's just a difference between the instruction sets.) Applications for which 64-bit arithmetic is a bottleneck will also benefit, but I think those are relatively rare. -- BenRG (talk) 23:55, 13 August 2008 (UTC)

Default Font-Size on a Macintosh?

Hello - So I recently have been going nuts trying to figure out why this one web design project wouldn't display correctly on one of my co-workers' computers. I finally figured it out; he uses a Macintosh, and the default font size in both Firefox 3 and Safari seems to have been set to 12 px/pt. This is actually a big deal when you're designing with relative units (as I was).

So my question is: how common is this? Would anyone using a Mac be willing to check for me what their default font size is set to? (You can do so on Firefox 3 by going to Firefox -> Preferences; it's under the Content tab. In Safari, it's Safari->Preferences, under the Appearance tab. I have no clue how to find this out in IE for the Mac). Please let me know. It seems like a small thing, but it's actually a, uh, relatively big deal when you're trying to design accessible websites. Thanks! --Brasswatchman (talk) 22:54, 12 August 2008 (UTC)

On my Mac the standard font is Times 16 and fixed-width is Courier 13. To the best of my recollection I never changed that, so it may be "factory setting". I use Mac OS X 10.4.11. PS: Safari... --Cookatoo.ergo.ZooM (talk) 23:21, 12 August 2008 (UTC)

Both Safari and Firefox on my Mac have Times 16 and Courier 13 as the default size. Jkasd 00:02, 13 August 2008 (UTC)

Why is it a big deal? Just set the default font size for your page in the BODY tag, and then everything will be relative to that. It won't keep people from resizing or decreasing the size if they need to. --98.217.8.46 (talk) 00:36, 13 August 2008 (UTC)

Trick is, I'm not sure if that's true. I had some trouble resizing with a default font size set in IE 6. (Which, argh, yes, I still have to support, unfortunately). So I'm going to have to figure out something else. Anyway, thanks, everyone. Really appreciate the help. --Brasswatchman (talk) 13:13, 13 August 2008 (UTC)

Well, IE6 is IE6. There's only so much back-bending you can do. Personally I would assume—perhaps erroneously, but who knows—that if someone is currently on the web and needs the easy capability to enlarge site content, that they have switched from IE6 long ago, because it utterly fails at this in many instances with CSS. That is, yours would not be the first site they'd come across that wouldn't support that, with IE6. (I often use the "first site" rule myself to determine whether it is worth bending over backwards to cater to specific, non-fatal browser deficiencies.) --98.217.8.46 (talk) 14:49, 13 August 2008 (UTC)

ls/dir command in C

How does one do a directory search in GNU C? I can't figure out for the life of me how to do it, and online documentation is simply horrendous. Magog the Ogre (talk) 00:22, 13 August 2008 (UTC)

See this example. -- kainaw™ 00:24, 13 August 2008 (UTC)

The easiest way to get the most powerful result is to use the Unix philosophy: use find and read its input with popen() or similar. --Sean 01:13, 13 August 2008 (UTC)

And instead of writing output with puts, putchar, and printf, you could system("echo")! Running external commands to avoid reinventing complex functionality is a good idea, but readdir isn't that complex. --tcsetattr (talk / contribs) 04:58, 13 August 2008 (UTC)

Moreover, relying on the formatting of the output of external programs makes for fragile and unportable programs. The behaviour of readdir is specified by POSIX; the output format of programs like find and ls isn't, and can vary remarkably between platforms and revisions. For example, the (unaliased) ls -l format varies between a RHEL3 machine and a current Ubuntu one (and they're both using versions of ls from GNU fileutils/coreutils, albeit several years apart). Unfortunately the "unix philosphy" breaks down in the face of the (often pointless) diversity of details and options for command line programs. I've so often seen how, perhaps contrary to how one might expect, C language source code turns out to be more portable (with fewer annoying checks for "if we're running on x then y") across *nix versions and variants than an equivalent shell script. Doris the Nymph (talk) 11:18, 13 August 2008 (UTC)

Actually POSIX does specify some strict output formats now. Even for ls -l, historically intended only for human consumption (see <http://www.opengroup.org/onlinepubs/009695399/utilities/ls.html#tag_04_81_10>). Good news for shell script writers. Still, C programmers should use readdir(), scandir(), glob(), ftw() rather than popen()ing ls and find. --tcsetattr (talk / contribs) 20:05, 13 August 2008 (UTC)

I have to point out, though, that none of the functions you just mentioned are part of the C standard, and programs using them will probably only be portable to Unixy environments. Visual C++ doesn't have readdir() or scandir() or glob() to my knowledge, though it does have popen(). There's no portable way to read the contents of a directory in C. -- BenRG (talk) 00:02, 14 August 2008 (UTC)

Working with stupid Vista

Since it first came out, I've enjoyed Rollercoaster Tycoon and its expansion packs, so I'm just now trying to install it on my relatively new Vista-equipped HP laptop, which has only one user account, an administrator account of course. The original works fine, but the other CD (both expansions, Corkscrew Follies and Loopy Landscapes, together) gives me an "Access Denied" message because there's some sort of error. Looking online, I find that there are other people complaining on various online forums about the same problem, but others who get it to work fine. I've had other problems with the computer not always treating me like the administrator, and I'm wondering if this is a factor in the Loopy Landscapes access problem. Any ideas on what I can do to get around the administrator thing, so that it lets me perform administrator duties without holding me up like this? Nyttend (talk) 04:30, 13 August 2008 (UTC)

My only suggestion is trying to run it in compatibility mode while using an administrator account. If you do not know how to get into Compatibility you need to right click over the .exe file in the CD used for installing and go to the bottom and click properties and look for one for compatibility. Change it to XP. To get to the CD you go to (this is assuming your Disc drive is Drive F but it should be obvious if the CD is in) my computer and right click over drive f and click on browse or something of that nature. Running it as XP should work and make sure to log in as an admin...also..you may want to turn off M$ security settings. Rgoodermote^{Not an admin}  06:41, 13 August 2008 (UTC)

Still doesn't work: I made Setup.exe for the original RCT work as if it were in XP, made the original RCT work as if it were in XP (program worked fine), made Setup.exe for the expansions work as if were in XP, made the expension work as if it were in XP, but it still gave me the same access problem bit and failed to open. Can you tell me how to turn off "M$" security settings, and explain what M$ means? Nyttend (talk) 16:28, 13 August 2008 (UTC)

If it's the game not running properly, try running it with elevated permissions: r-click the shortcut, click 'run as administrator'. If it's the installer for the expansion packs, find setup.exe on the disc and run that as administrator. If you installed the game to C:\Program Files, try uninstalling the game, creating a new folder like C:\Games, and reinstalling it there (backup your saves, obviously). For compatibility mode on a game that old; I'd set it to NT4 or perhaps 2000, rather than XP - I know this works for Homeworld. CaptainVindaloo ^{t c e} 18:32, 13 August 2008 (UTC)

You might want to disable the User Account Control for a while and see if that helps. That can be done from Control Panel -> User Accounts. I wasn't able, for example, to install one of the drivers (an MSI package, not an executable file) when it was on (the setup wizard was telling me to log in as an administrator, although I am one!)  ARTYOM  19:16, 13 August 2008 (UTC)

I've disabled User Account Control and set both the install and the program itself — both for the original version (which still works fine) and for the expansions — to work on 98/ME (we never had Windows 2000 or NT, but it worked for us fine on ME), but all it does is give me the same error message as before. Should I just give up? Nyttend (talk) 23:46, 13 August 2008 (UTC)

When exactly does it give you the error? When you double click on the setup file, or somewhere through the installation process? Also, you said you were trying to install this stuff from a CD, right?  ARTYOM  01:08, 14 August 2008 (UTC)

No, setup and installation both seem to work fine: it's when I actually open the program that I get a message. And yes, I'm working this from the original CD. Nyttend (talk) 01:32, 14 August 2008 (UTC)

Okay. When you right click on the program's executable file and go to properties, do you have a Security tab in there? If so, go to it, locate your username in the top list, and see if all permissions in the bottom list are set to "Allow". The only time I was ever getting an "Access denied" error trying to open a file was when my user account didn't have permissions to open it.  ARTYOM  01:42, 14 August 2008 (UTC)

Does law enforcement ever bust all these people doing DDoS attacks?

Does law enforcement ever bust all these people doing DDoS attacks? Basically lots of websites I visit that are on dedicated servers sometimes go down due to DDoS. I also hear about lots of DDoS attacks on other sites I don't go to, as well. Also pretty much every shared website host I've hosted with if it's popular will get regular DDoS attacks. It seems like law enforcement just does nothing except for one time when someone hit yahoo, ebay, and some billionaire companies. Is law enforcement every working to track down these people or does law enforcement just not care? William Ortiz (talk) 16:14, 13 August 2008 (UTC)

Americans and Western Europeans who perpetrate DDOS attacks are often caught. I've seen news stories every few months about them getting arrested. Castle Cops caught one a while ago. However, most of the computers that perform DDOS attacks are zombies. And many of the bot operators are in third-world countries that do not care about it. Many of the zombies also "reflect" their packets off of other computers by spoofing their IP addresses. Thus, the computers that a victim's server sees are simply other computers under attack attempting to reply to a victim that never sent a packet. That's why many of the people who get caught are the amateurs who don't know how to hide their tracks, often teenagers.--67.166.55.248 (talk) 16:21, 13 August 2008 (UTC)

According to botnet, several have been shut down by law enforcement. See for example this story, about a 1.5-million strong botnet being used for DDoS-based extortion. Algebraist 16:23, 13 August 2008 (UTC)

Wireless network problem

I have a password protected network in my house, through a Belkin G 2.4ghz router.

I then have to reset my network adapter to get back online. Is there anyway to fix this?71.212.190.75 (talk) 02:09, 14 August 2008 (UTC)

Nothing is actually "broken". Your getting disconnected when your laptop goes into "Standby" mode. You just need to use your WiFi software and reestablish connection. The reason why resetting your adapter works is because it automatically does the reconnect when it's finished resetting. One way to change that behavior is to change your settings to not go into standby mode when you close the lid. ---J.S (T/C/WRE) 02:14, 14 August 2008 (UTC)

Why do people use Linux when Unix is now "free"

Why do many proponents of FOSS (Free and Open Source Software - note Free = speech) prefer Linux over Unix? Unix is also now "Free" with FreeBSD, and many other flavors of Unix released for free. I understand, they're pretty similar, and that Linux was created to be a Unix close, but Unix seems to be the one OS which has been there from the start, and one tested by many, many years, and perfection. So why don't people switch over to Unix? —Preceding unsigned comment added by Legolas52 (talk • contribs) 04:58, 14 August 2008 (UTC)

Good question. Frankly, I wonder why Linux ever took off in the first place. They should have just waited a couple of years and then they would have had a much-less buggy 4.4 BSD to use. And in case anyone was planning to bring it up, the GPL is worthless. You could save yourselves the trouble and release your software into the Public Domain. Or better yet, say something like "Here's the source code. Have fun." That way, we wouldn't have to deal with wannabe lawyers like Stallman.--67.166.55.248 (talk) 05:12, 14 August 2008 (UTC)

Why do people use Linux when Vista is "cheaper"? --mboverload@ 07:28, 14 August 2008 (UTC)

As a FreeBSD user, and former committer, I am sympathetic to the question. The "short answer" is that there were legal problems associated with the BSD code, which delayed its adoption. Linux gained a foothold during these troubles, and it retained the leading market-share position ever since. (When I started using both, in the mid-1990s, my perception was that Linux was for people who hated Microsoft, and *BSD was for people who loved Unix.) -- Coneslayer (talk) 12:17, 14 August 2008 (UTC)

Despite what .248 said above, I think it *is* due to the GPL that it got popular with developers. I personally would be very annoyed if a commercial company took something I had written, closed the source, introduced incompatibilities with my version, and made a ton of money while giving nothing back. I don't believe in the "software should be free for moral reasons" stuff, but from a practical point of view the GPL is a lot more attractive than BSD. --Sean 14:42, 14 August 2008 (UTC)

Actually, the GPL is not a contract, so none of the parties to it are bound by it. For valid contract, you need consideration (payment). So, even if you gave it to them, you could still get it back if you wanted. The only thing the GPL does is say what you'd like to have done with it. That's why it's worthless. No one needs the GPL, including Wikipedia, and anyone who goes around quoting the GPL and Stallman is acting out a bizarre tragedy.--67.166.55.248 (talk) 18:26, 14 August 2008 (UTC)

This is pretty completely false. Courts have (finally) ruled that the GPL is legally binding. The naive summary is that without agreeing to the GPL you do not have the right to redistribute GPLed code. (And would therefore be guilty of copyright violation.) If you don't redistribute the code, no one cares if you're bound by it or not. APL (talk) 18:45, 14 August 2008 (UTC)

I have used a version of Mantis before which was excellent, however I have one limitation that I don't really want to go through all the hassle of setting up a server-side bug tracker on a server I don't actually have. Therefore I was wondering if there are any solutions involving the following:

a) Free hosted bug tracking site (something like sourceforge entered my mind, but that's a bit more general, I literally want to track bugs).

b) Client side bug tracking program

At the end of the day, I can resort to good ol' Notepad but it would be nice to use some kind of organised system. Any thoughts? 81.187.252.174 (talk) 15:57, 14 August 2008 (UTC)

Haven't got any personal recommendations but WP does have a list Comparison_of_issue_tracking_systems - X201 (talk) 16:08, 14 August 2008 (UTC)

Wikipedia, NASA, [[[Facebook]] and Mozilla all uses Bugzilla. Other then that I don't know much about how it works or what is required for it. It might be server-side, but I have no clue. If your the only one imputing tickets and mantianing thier status, why not just an excel spreadsheet or something like that? ---J.S (T/C/WRE) 19:55, 15 August 2008 (UTC)

IP

Is it possible to know if a particular IP address is shared IP or not? Otolemur crassicaudatus (talk) 17:34, 14 August 2008 (UTC)

Not really. There is no "this is a shared IP" setting. You just do a lookup and see who owns it. If it is an internet service, it is likely a shared IP. -- kainaw™ 17:49, 14 August 2008 (UTC)

Do you mean a Dynamic IP, or an IP that multiple computers are sharing at once, through network address translation? (The answer is probably "no" either way, but it's good to know what we're talking about.) -- Coneslayer (talk) 17:58, 14 August 2008 (UTC)

You can get some good hints by doing a whois on the IP address. The Whois will tell you who owns it and from there you can google search the particular ISP. If it's owned, for example, by Comcast then it's -basically- a static IP address of a single cable customer. If it's owned by a small business, school, etc, then everyone in that organization will likely be sharing it. In other cases, it's not necessary clear. ---J.S (T/C/WRE) 19:48, 15 August 2008 (UTC)

Could do an RBL on lookup on, for example, [5]. This will tell you if the IP is on any email blacklists and why; dynamic IPs are usually on email blacklists. Other types of "shared" IPs might not be. 24.76.161.28 (talk) 01:24, 16 August 2008 (UTC)

DVD problem

I have a couple of favorite standard DVD's that don't bear evidence of major scratching, however, they no longer play properly. It seems like both of them work fine for the first half of the presentation (movie) but when I try to view the later chapters it just freezes and I wind up having to eject the disc. (I have tried them on several different players and computers) Is there any cause for this other than scratching? More importantly, is their there any way to repair the discs? I have been looking at devices that actually "sand" off the outer surface to remove scratches, but I am really not sure scratches are the problem. any suggestions? thanks and cheers, 10draftsdeep (talk) 18:34, 14 August 2008 (UTC)

DVDs can fail for various other reasons. See CD rot (it's not a great article but it has some links). In addition to what's mentioned there, if it's a DVD±R(W), the dye may have faded or diffused. None of these problems are repairable, and they'll just get worse with time. If you can find any DVD-ROM drive that can still read the disc, even very slowly with many retries, rip it and burn a new copy. If it's a commercial disc and it failed through no fault of your own, you might be able to get it replaced (it might have come from a defective batch, for one thing). -- BenRG (talk) 22:04, 14 August 2008 (UTC)

Thanks for the advice. It is actually a commercial disc that worked great for a few months and then started to fail. I am sure there is litte possibility of free replacement. If the problem is due to scratching (I have others that are scratched) are the "sanding" devices effective for buffing off the top layer and restoring the discs? Thanks again and cheers, 10draftsdeep (talk) 13:58, 15 August 2008 (UTC)

Yes, resurfacing devices (we use something called Disc Doctor, I think) do work. We had a bought copy of Finding Nemo that always cut out just before the end; there were no visible scratches, but the repair kit fixed the problem after one go through. It's fixed a number of discs for us with no problems. Matt Deres (talk) 20:08, 15 August 2008 (UTC)

HP LaserJet M1522nf MFP

Dear Wikipedians:

Is it possible to use an HP LaserJet M1522nf MFP as a modem to dial-up BBS's and dialup Internet?

In other words, is there a way of mapping an HP LaserJet M1522nf MFP unit attached to the local network as a modem device under Windows XP?

Thanks.

SIP outbound proxy (media relay) software suite

Hi,

Could I get some pointers to software that implements an Outbound Proxy, media relay, or relay stream for the Session Initiation Protocol (SIP)? I'd prefer open-source licensed software, but that's not required. I'd like to run it on Linux or a Unix variant.

The outbound proxy server should be able to relay the SIP message requests between other SIP agents and its clients, along with RTP audio streams. A client behind a symmetric NAT should be able to connect to it to connect to other SIP agents, and it should relay incoming requests from external SIP agents to contacts registered on it.

If it's any help, a more concrete example of such a SIP relay/proxy would be FreeWorldDialup's NAT outbound proxy (fwdnat2.pulver.com:5060).

(Even if you don't think a particular software suite supports everything that I mentioned, it might be worth noting here anyway. I'm open to ideas, and I'm willing to modifying code to make it work.)

Thanks,

Posible answers include :

• CyberPadWrite on a real pad of paper and everything you write down is recorded and can later be downloaded to a PC. (I think there are a couple of competing devices that work in this fashion, but this was the only one I could find.) I've never used one of these so I can't vouch for them.
• Palm Pilot Palm Pilot is a nice simple PDA without the complexity of a WindowsCE device. Of course, Mine is an ancient Palm III, so I can't vouch for modern ones either.
• Tablet PC Most 'complicated' and computer-like of things that could qualify as a "digital notepad". Still, you could set one up to automatically launch "MS Journal", which is a very nice pen&paper simulator. I've got a tablet, it's pretty neat. I use it for browsing the web more than anything, actually. It's a handy way to view "how-to" websites.

C++ and java programming

Hi. I'm a bit new to all this programming thing, and I'm reading about C++ and Java. I read on WIkipedia that C++ is mostly used for applications and system.

My question is then: Can you program a system or large fully funtional programs with java, if yes, is it a good idea to used java for systems of large applications?

Thanks. —Preceding unsigned comment added by 194.239.172.228 (talk) 07:23, 15 August 2008 (UTC)

Yes, you can programme a large fully functional programme with Java, but it's not very often done because of the slower speed of Java due to the fact that it runs on a virtual machine. (Yes you can use JNI but you wouldn't be programming in Java if you use that, would you?) --antilived^{T | C | G} 08:48, 15 August 2008 (UTC)

These days, in my experience it's a myth that Java is inherently slow. JIT compilers are the norm; startup takes longer, but once the application runs, it's often not much slower than C++. Unless speed is critical and you're doing massive amounts of calculations, I doesn't really matter. --Tokikake (talk) 13:00, 15 August 2008 (UTC)

Also, it depends on the resources in your company. For example your developers might be Java experts in which case the company would be forced to make a decision to write a new large system using Java as the front end, rather than hire C programmers and thereafter teach them the business etc. Of course, your system would most likely comprise some sort of database - these database calls (JDBC) can be made from within java to, for example, stored procedures within the database, so this would eliminate performance restrictions as business rules and functions can be stored and executed in the database code. Sandman30s (talk) 11:44, 15 August 2008 (UTC)

It is difficult to compare. The other reason may be because Java programs generally have more features in them anyway, compared to C+. Vuze is slower than Transmission (BitTorrent client). But why? Because Vuze is Java and Transmission is in C+, or because Vuze does absolutely everything you could possibly want, and even what you would never want?84.13.87.28 (talk) 13:51, 15 August 2008 (UTC)

The primary issue is the need for a native executable. In general, people want programs that just run. They don't want to deal with a virtual machine. You also have issues with the virtual machine upgrading and causing errors in your program. So, C/C++ is commonly used to make a native executable that just runs on whatever operating system it was designed for. There are third-party programs that can turn a Java program into a native executable for Windows, but the end result is rather huge because weird licensing issues require you to bundle every single bit of Java into the executable instead of only including what you need. All in all, if the JIT compilation would allow you to save the executable, Java would be just as fast as C/C++ and be very portable (send the executable to anyone with the same operating system). Sun will not allow that to happen, so Java is stuck in virtual machine hell. -- kainaw™ 16:36, 15 August 2008 (UTC)

See also: JavaOS - an OS written in Java and with the JVM as a fundamental component. ---J.S (T/C/WRE) 17:27, 15 August 2008 (UTC)

I don't think it's true that "if the JIT compilation would allow you to save the executable, Java would be just as fast as C/C++". There are other things that slow Java down, like

• Bounds checks on every array access. Some C++ implementations let you turn this on for the standard containers, but usually it's off.
• More dynamic binding (virtual function calls), I think. They're harder to predict and can't be inlined.
• A lot more dynamic type casting and checking, to work around limitations and gaping holes in Java's static type system. C++ has dynamic_cast and typeid, but they aren't often used. The C++ equivalent of casting from Object is casting from void*, which has no runtime cost on most implementations. (It's also unsafe, but we're talking about speed here.)
• All data is heap allocated except for a few magical built-in types. This costs an extra word for the reference, extra instructions to dereference it, and allocation and garbage collection overhead, and it hurts memory locality. It also means Java has a runtime abstraction penalty that doesn't exist in C++. If you declare a variable of type complex<double> in C++ it behaves pretty much like two variables of type double from a code generation perspective, even though complex is not special to the compiler. In Java a class with two double fields is a lot more expensive than two doubles. The only way to get good performance from complex numbers is to make them magical to the compiler or write all the complex arithmetic out by hand. In C++ you can wrap a class to provide a different interface (containment and delegation—can't believe that's a redlink) with no runtime cost. In Java every layer of wrapping creates another heap allocated object and another reference. This kind of wrapping is good programming practice and it's common in both Java and C++.

There are probably also cultural differences that have nothing to do with the languages as such, like

• Java probably attracts more inexperienced programmers who don't notice that they're writing an O(n³) sorting algorithm nor know why that's a bad thing.
• People who are trying to write fast software (and are going to put effort into optimizing it) are more likely to choose C++, making the higher speed a self-fulfilling prophecy.

Laptop battery no longer charges

Hello. I have a Lenovo/Thinkpad laptop (purchased new May 2007) running WIndows Vista. Yesterday, without warning or any apparent reason, I noticed that--according to the battery display icon on the right side of the taskbar--my battery is no longer capable of charging. When plugged in, the computer runs fine. When I pull out the power cord, the battery (now at 35%) begins to deplete as it normally would, but when I reinsert the power cord, the battery will begin to charge back up. Any ideas? Thank you very much for your help! —Preceding unsigned comment added by 24.211.242.80 (talk) 11:29, 15 August 2008 (UTC)

For Lenovo Thinkpads, the battery has a "Charge when below x%, charge to y% then stop" function. You can check whether if your computer is always kept at full charge (charge after batter drops below 96%) or if a different scheme is enabled by clicking on the battery in the taskbar and going to the Lenovo power manager, Battery information tab, battery maintenance button. Coolotter88 (talk) 12:37, 15 August 2008 (UTC)

Unfortunately I don't think that's the solution, becuase it's set to automatically charge when below 94%, and it's already far below 94%. I didn't change my battery settings at all recently so that's why the situation is so confusing. -- 24.211.242.80 (talk) 12:57, 15 August 2008 (UTC)

Your battery may be defective or simply outside of it's useful life. Call the support line for Lenovo (IBM?) and see if it's still under warrenty. Might get lucky and get it replaced for free. ---J.S (T/C/WRE) 18:08, 15 August 2008 (UTC)

btw - Lenovo batteries have a 1 year warranty. --mboverload@ 02:13, 16 August 2008 (UTC)

My older laptop used to do that long before the battery went completely dead and unrechargeable. I guess sometimes the batteries just won't charge completely for a while, but will still charge later at some point.  ARTYOM  03:56, 16 August 2008 (UTC)

Where I work we deal with a ton of Dell laptops, and their batteries. 30 or so. Three times now the battery failed within a few months of the warranty expiration date.

This is a longshot, but Do you have one monitor connected to a graphics card equipped for dual monitors?

I forget exactly how I fixed it, but the computer became usable again just by switching the monitor to the other output. APL (talk) 22:46, 15 August 2008 (UTC)

The message appears to be legit. It sounds like a video driver problem, in which case I'm surprised you can't boot into safe mode. Is there any chance you're doing it wrong? APL's suggestion sounds good also. Another thing you can try is to log in, then press Win+R (which opens the Run dialog), then type "cmd" followed by Enter (which opens a command prompt), then press Alt+Enter (which makes the command prompt go full screen, which changes the video mode, which might make the video card come back to life).

Does it give you an error message at the end of the list of files when you try to start in the safe mode?

variable declaration in c++

char varname1 means varname1 is a character, while char *varname2 means varname2 is the address of a memory location that contains a character.

See Pointer (computing). "char x" will automatically allocate memory for you until "x" goes out of scope (normally this is at the end of the function). "char *x" won't allocate (or de-allocate) memory - it will expect you to allocate and de-allocate memory using the new and delete keywords (or using malloc and free). The big advantage is that you can just pass the pointer about to all the functions which need to use it, which is normally much smaller than copying whole objects (so is faster and uses less memory). --h2g2bob (talk) 22:56, 16 August 2008 (UTC)

Audio Software

My younger sibling has run riot on my computer and deleted the software that I used get sound from my speakers! Is there any free software I can download from the internet so I can listen to music on my computer once again? I usually use windows media player to do so - but I don't know if thats relevant. There is certainly no damage to my speakers or cables unplugged etc. I'm sure I can't get any sound because the audio software has been deleted.

networking

hi...someone recently told me that it is possible to connect 2 computers(or for that matter a whole bunch of computers) using normal telephone wires(RJ 15 cables), without using RJ 45 cables if both the computers have modem...is this possible...if so please give complete details...also he said that digital data can be transferred over our electricity lines...is this possible????????

Need help copying files to external hard drive

I'm trying to copy all the (copyable) files from a 2nd hard drive on a PC to an external drive. I want the individual files easily accessible when the external drive is plugged into another PC, so backup programs are not necessarily the right solution. I tried drag-and-dropping the files from the source hard drive to the external drive, but the copying aborted when Windows came across an uncopyable file. I also tried XCOPY, with the /C /E /H options specified, but XCOPY crashed half way into the copying process, saying "Insufficient memory". That looks like a bug or limitation of XCOPY. Anyway to copy large number of files in Windows without having the operation aborted by uncopyable files? —Preceding unsigned comment added by 71.162.242.81 (talk) 17:08, 16 August 2008 (UTC)

• Booting into safe-mode might make the operation more likely a success.
• Do you really want to backup every file on your hard drive? Creating a batch-file to copy over the specific folders you care about will likely avoid the files are are being locked.
• You can boot using a Linux live-CD and copy the files within Linux. Just make sure everything is formatted in NTFS so windows can use it.
• Norton Ghost might be a viable solution. ---J.S (T/C/WRE) 18:28, 16 August 2008 (UTC)

It's been awhile since I've done something like this, but I'm pretty sure you can do something like this in your administrator tools, make it so that some users don't have a taskbar. (You do things like this when you are setting up permanent terminals, for example.)

Well, I don't know about doing it through the registry, but it can be done by moving the cursor to make it double sided (so the size of the taskbar can be changed) and drag it all the way to the bottom of the screen. -- Ζρς ι'β' ^¡hábleme! 20:44, 16 August 2008 (UTC)

Undeleteable Folder on Desktop

This folder is located on my desktop just to let you know my desktop is mapped to "F:\Data\Nathan\Desktop\" and folder is named " " (no quotes) making the path "F:\Data\Nathan\Desktop\ " (reminder: include quotes if in command prompt instruction if used or it won't know the space is part of the path) the folder can't be moved renamed deleted please help me delete it. I can't remember know how I created it. I don't if it matters but i did a bit of rresearch and it turns out i most most likely did i probably did hold alt then 0160 on numpad then release alt when editing the filename to get like that. Xor24 ^{talk to me} 22:50, 16 August 2008 (UTC)

What error do you see when you try and delete it? Folder is in use/bad permissions/something else? Which windows version? --h2g2bob (talk) 23:20, 16 August 2008 (UTC)

I recieve no error message just doesnt delete im using vista ultimate 64 bit

Your best bet is probably to boot into safe-mode and log in as the default administrator and delete through command prompt. You may also want to check the permissions on the folder (by right-clicking on it assuming you have Win XP. I don't know about other OS's) and make sure that it isn't protected. (By the way, I can't make a folder with no name. It automatically renames it "New Folder" when I try to enter a blank name.) Ζρς ι'β' ^¡hábleme! 23:30, 16 August 2008 (UTC)

If the name is really a single space (I'm confused by your "no sapce" comment), and the directory is empty, you can probably remove it by opening a command prompt and typing the following:

       rmdir "\\?\F:\Data\Nathan\Desktop\ "

If the directory is not empty you could try rmdir /s instead of rmdir, but I take no responsibility for lost data if you do. Another possibility is to type

       f:
       cd \Data\Nathan\Desktop
       dir /x

it should say no quotes im sorry

which will list the short names of all the files in that directory. The short name should be typeable even if the full name isn't.

The "\\?\" prefix turns off Win32 pathname parsing and just forwards the raw path on to the NT kernel. One of the things the Win32 pathname parser does is strip off trailing spaces, but the parser is shoddily written and there are various ways to get it to pass otherwise illegal file names to the kernel. For example, typing this at a command prompt:

       echo gotcha > "  :-"

will create a zero-length file in the current directory whose name is " ", which you then won't be able to delete except with a trick like the one above. You can also use this to create a file named "..". I take no responsibility for any damage you might do to your system this way. -- BenRG (talk) 00:01, 17 August 2008 (UTC)

Oops, I didn't notice the last bit of your comment. Alt+0160 will produce a non-breaking space, which looks just like an ordinary space. But Windows doesn't give it the same special treatment it gives ordinary space, so I can't understand why you would have trouble renaming it. I just tried renaming a file to that and back and it worked fine. -- BenRG (talk) 00:08, 17 August 2008 (UTC)

Not to hi-jack anyone's question, but just as an aside, how does echo gotcha > "  :-" work to create a file? (Not disputing that it does, just wondering how). Ζρς ι'β' ^¡hábleme! 00:12, 17 August 2008 (UTC)

The ">" operator does it, I think. ---J.S (T/C/WRE) 01:36, 17 August 2008 (UTC)

The echo gotcha part prints the word "gotcha", and the > redirects it to a file named "  :-". The NTFS filesystem supports alternate streams, so this creates an empty file " ", with a stream named "-". (For example, when a program tries to access file "foo:bar", in reality it's accessing stream "bar" of file "foo".) --grawity 13:06, 17 August 2008 (UTC)

Alt + 0160 is Windows' key sequence for entering a non-breaking space. The character looks like a space but is logically a different character. If you try to delete the folder from a Windows command interpreter, using something like

rmdir "F:\Data\Nathan\Desktop\ "

you'll need to type in the last character of the path (before the closing quote) using the special key sequence, otherwise you won't be specifying the correct path. If the folder is not empty, you can manually make it empty first or use the /S option to force deletion. --71.162.242.81 (talk) 15:06, 17 August 2008 (UTC)

nothing suggested worked but thanks much for explaining that it isn't technically a space that helped when i did rmdir "\\?\F:\Data\Nathan\Desktop\ " making sure it wasnt a space i got the error message on the command prompt access is denied i did the thing were u right and choose run as admin and got same error

Digital cable =HDTV ??? (a few questions)

My cable company (Comcast) offers both analog and digital cable. What is the relationship between "digital cable" and HDTV? Does it make any sense to pay extra for digital cable and use it with a conventional TV? Will digital cable work with a Tivo Series 2? ike9898 (talk) 00:30, 17 August 2008 (UTC)

I would say Digital cable = more channels, not necessarily High-definition television. 12.169.180.178 (talk) 00:44, 17 August 2008 (UTC)

If the package your getting has high-def, they will be very clear about it. It's the main selling point, after all. If it's just "digital cable" then all your getting is the non-basic package and the ability to use things like On Demand, etc. ---J.S (T/C/WRE) 01:38, 17 August 2008 (UTC)

HDTV is broadcast (i.e. over the air) using a digital transmission system, but there isn't really a relationship between "digital cable" and HDTV. However, there is probably not enough bandwidth available on an analog cable system to support the amount of data needed for HDTV signals, so your local cable company will most likely require a digital box to supply HD programming. In my area, Comcast has been steadily moving more and more channels from their analog service to digital, so if the channels you want to watch are only on digital, then it might make sense to pay the additional cost. The digital systems usually also provide for additional features, such as "on demand" shows and movies, which aren't available on analog systems. Finally, yes, digital cable will work with a TiVo Series 2, I had that set up for many years. The output from most standard cable boxes is analog anyway, which is why the upcoming DTV transition only affects people who don't have cable or satellite systems. --LarryMac | Talk 15:49, 18 August 2008 (UTC)

One caution on digital TV, it's far less fault-tolerant than analog. So, any tiny bit of interference, which under analog would have just caused snow, lines going across the screen, or shadows, will now cause trhe signal to break up into unwatchable garbage. So, if you have to choose between the two, I'd be reluctant to switch. On the other hand, if they offer both, then you will still have analog as a backup. Another caution, if they say their digital package "includes HDTV", that may very well mean only a few stations are HDTV, and the rest are all standard def. StuRat (talk) 01:10, 19 August 2008 (UTC)

DVD drive problem

Whats going on with my DVD drive? Its opening and closing every 20 seconds or so. It won't stop. I've checked the eject button, its definitely not stuck down, and I've run virus checks and they are clear.

Its not been used for weeks and there's no reason why it should suddenly spring into life. It can be fine for a while after I turn the computer on, but once I've got a few programs running it starts again. I don't want to point any fingers but it all seamed to start after I got the latest update for Vista (I know its probably not that but I'm clutching at straws). Any help would be appreciated. 144.137.206.217 (talk) 09:49, 17 August 2008 (UTC)

I think you might have had the right idea with the eject button being jammed down, but if it's not physically jammed, perhaps the sensor is just malfunctioning and reporting that it is. This might be temperature sensitive and may only happen when the computer heats up a bit. If so, you might want to take the case off the PC. If that doesn't help, dismount the DVD drive and set it on the table, still plugged in, and see if that makes a diff. StuRat (talk) 00:57, 19 August 2008 (UTC)

Del.icio.us tags

apple vs. pc (just a few (very specific) questions)

Hello Guys,

My current laptop (a dell) has had a good life (4 years) but is now dying on me and needs replacing. I'm really tempted to go with another Dell becuase, well, i like them but i'm quite tempted to try apple as i'll be doing doing some graphic design and they are supposed to be better. My only problems are these:

1)Apple only release new products once a year. For obvious reasons, i'd like to get a new version but apple are being really cagey about when the new ones are going to come out (as, i guess they'll think that buying one now is an option - which its not becuase surely i'll just be ripping myself off?). Does any one know when the new release date is? (i live in the UK btw and have heard rumours that its in september)

2) i'm thinking that the reasons my computer keeps crashing/freezing now is becuase windows is crap -is this fair or do Apple's 'get old' just the same? Am i expecting to much?

3)as i said, i'll be doing some graphic design on it - using adobe in a Mac does seems more intuitive than on a PC but does any one know if the end results are any different? surely its just the same?

4) the wikipedia article on apple paints them as environmental monsters (unlike Dell who i've always admired in this respect). Is this really true? i know greenpeace can over-egg the pudding sometimes but Steve Jobs' response was, well, dissapointing to say the least!

anyway, any advice you guys have would be gratefully recieved.

Thanks,82.22.4.63 (talk) 15:53, 17 August 2008 (UTC)

Regarding number 2 - XP is not "crap" by default. However, years of not taking care of it will lead to poor performance. Mac is a bit more resistant to neglect.

Regarding number 3 - Mac is favored by graphics design firms. I don't know why that is, but it's something to consiter if your trying to get into graphics design.

The other thing worth thinking about is this: XP-based systems tend to be cheaper. That means you can usualy get a better computer for your dollar. ---J.S (T/C/WRE) 16:25, 17 August 2008 (UTC)

1. Apple is notoriously secretive about release dates.

2. Windows machines "degrade" pretty quickly in terms of the OS getting bogged down with lots of little unnecessary bits that decrease its speed and performance. OS X is better at dealing with that, though not immune. At the end of the day, you'll spend less time per day keeping a Mac up to speed and malware free than you will on a Windows machine. Whether that matters to you much is of course a matter of opinion (and personal confidence in your own abilities to keep a Windows machine malware free).

3. Doesn't matter anymore, if it ever did in recent times. End results are identical and by this point totally compatible with all of the Adobe software, anyway.

4. Don't know. --98.217.8.46 (talk) 17:33, 17 August 2008 (UTC)

"Environmental monsters" isn't completely fair, there is positive stuff in the article [6], like the business about LCD screens. There isn't any comparison made to PC's. A mac seems to get nearly twice the battery power on it's native OSX than XP/Vista using Boot Camp, and the Rockbox alternative ipod firmware doesn't get the same record as the proprietary stuff. 78.150.238.131 (talk) 18:00, 17 August 2008 (UTC)

1. I don't know.
2. It's probably crashing because of something you did. Windows XP is well-designed, and contains many sophisticated error-handling features that OS X lacks. It's much better than Windows 98 or even 2000. But there are a lot of programs written for XP, so if you start installing every program you can find, they will begin conflicting with each other. They also mess with your system settings. XP also supports more types of hardware than OS X. Apple makes most of the hardware you use on a Mac, so there is less potential for hardware issues. I don't know what you mean by "crashing," but it could be due to too many programs running at once. It could also be that you've upgraded to newer applications, but haven't upgraded your hardware. This is a problem regardless of which platform you use. If it's a configuration issue, then you could certainly fix it if you don't mind learning a bit about how XP works. Macs can crash too, especially if your hardware is obsolete. In Windows, you have the hourglass. In Macs, you have the beach ball of death. I'm not a fan of Dell hardware, either. If it's a hardware issue, you might consider getting a Sony, instead. Also remember that if you have a PC and a Mac with identical specs, that PC is going to be faster out of the box. That's before you begin disabling all of the services you don't need on the PC.
3. It depends on your work. Most of the time, it doesn't matter. In the 90s, Macs had a much larger advantage. My movie-maker friend tells me that movies look a little better when they're made on Macs, though. He does work on both machines, but it could be that he uses Final Cut on the Mac, which isn't available on Windows. Macs also handle fonts a little better than PCs, so if you're in publishing, that may be a factor. They support PostScript Type 3 and give you more control over smoothing. Finally, they come with Fire Wire cards, which help when you're unloading large files from cameras, although you can put them into PCs, too.
   --J4n56t (talk) 18:43, 17 August 2008 (UTC)

1. If you are concerned about money, I wouldn't recommend an Apple. They are a bit pricey.

2. Windows is not necessarily crap. It, as other said previously, just degrades quickly over time. If you are vigilant, you can keep a Windows installation running well for years, and can simply reformat and reinstall it if it gets too bad. Mac OSX tends to "break down" less often, but my experience with Mac OSX, though limited, would suggest that if something does go wrong, it can be difficult to diagnose. All operating systems have their advantages and disadvantages. Ease of use is definitely one of Mac's advantages.

3. I have very little experience in the graphical arts world, but I have heard from avid Mac users (since the PowerPC and OS classic days) that they are "better" for graphic design. I have no clue why though.

4. In my opinion, manufacturing and operating a computer is not very environmental. Using a pencil and paper is. I have not heard much about either company stressing any green features of their computers or their methods.

And remember, Linux and other Unix systems are always an option. --Russoc4 (talk) 18:51, 17 August 2008 (UTC)

When you say your laptop is dying are you referring to the crashing and freezing you mention later? Most laptops come with a bootable CD/DVD or a hidden hard drive partition which can restore the hard drive to exactly the state it was in when the machine shipped. There's a good chance it will fix your problem. You will have to reinstall all your software, but you would have to do that with a new computer anyway. Of course you should copy all your personal files to an external hard drive or flash drive before you do this since the internal drive will be wiped completely clean. -- BenRG (talk) 19:49, 17 August 2008 (UTC)

In my experience, a large percentage of the "green" movement in the big-time businesses has been more marketing then substance.

There's been a lot of press lately on the way that "green" has become another label that companies slap on products to attract buyers. It's not always true, of course, that "green" things aren't actually green, but it's certainly become a consumer label, in the US anyway. As Michael Pollan says (about similar approaches in food), these sorts of products don't just sell us the product, but they sell us a story about the product as well ("We're Dan and Danny and we just want to make you the best gosh dang organic potato chip that you can have, full of natural ingredients and other Good Things™ for people."), one which is usually just advertising pablum. Which isn't to say one ought to just disregard environmental effects—just don't trust advertisers to be straight with you on them. --98.217.8.46 (talk) 03:54, 18 August 2008 (UTC)

I gotta say, I find it odd that your throwing a program away because you had an optional feature turned on. In any case, if you re-install it, it should give you the icon back so you an uninstall it. I'm not an expert on your OS, so I'm not 100% sure. ---J.S (T/C/WRE) 02:39, 18 August 2008 (UTC)

Well you see I thought it was a problem because I didn't know it was a feature. I thought it was a problem. And no the icon does not return, I've attempted re-install about half a dozen times now....--Xp54321 ^{(Hello! • Contribs)} 02:41, 18 August 2008 (UTC)

Oh. Sorry my assistance was worthless. :( ---J.S (T/C/WRE) 01:13, 19 August 2008 (UTC)

You can add items into your main menu using a similar process to how you deleted it. If you go back to that "Main Menu" preferences box. There should be a button with "New Item". In the next box that pops up, select "Application" from the drop down box, the name can be whatever you want, but I guess "AbiWord" will do. And for the command put "abiword" (no quotes, all lowercase). That should work. - Akamad (talk) 08:52, 18 August 2008 (UTC)

facebook wall spam

What is Facebook wall spam? How does it work? Does the sender have to install a compromised application on facebook? I recently got one that says:

Kyle Bronowski wrote at 9:59pm LOL! did you guys see what happened on the news today? check it out http://newvids.vidid902812.facecooks.com/

Is there anything I can do to stop it or minimize it in the future? Thanks. Kushal (talk) 03:36, 18 August 2008 (UTC)

Just delete it? I mean, is it that common? Your friend probably has 10 million messages telling them that their account is compromised already. I've gotten wall spam maybe once or twice—I don't think it's really worth spending much time worrying about at this point. (That is, as a user of Facebook, not as, say, an admin.) --98.217.8.46 (talk) 03:48, 18 August 2008 (UTC)

Also—it seems unlikely that you would ever be able to do anything on your end to stop wall spam if it is really being sent by compromised friends of yours. The place to stop it would have to be on the admin end of things—e.g. watching for accounts that post links to certain domains or whatever. --98.217.8.46 (talk) 03:50, 18 August 2008 (UTC)

Hmm. It seems to be becoming prevalent in my school network. I had seen a lot of it on my home page going back and forth across other people's walls but this is the first time that I got hit. I don't think I did anything lately that could have triggered this. Any more ideas?

If it's not actually being posted from your account then it's nothing to do with you (ie you didn't do anything to trigger it). The only thing you can do is get your not-so-lucky friends to change their passwords, since it's their accounts which are being used to post it. Their passwords have been phished - I visited the URL you posted and it redirects to a phony Facebook login page (fanebook.com - don't visit!). — Matt Eason ^{(Talk &#149; Contribs)} 18:53, 18 August 2008 (UTC)

Excel Question

I'm really bad at computing so please bear with me. I need to find all the values that satisfy a certain formula, say x² + y² + z² = 100, in Microsoft Excel 2003. I've no idea how to do this so is there someone who can help me? —Preceding unsigned comment added by 203.219.97.155 (talk) 10:12, 18 August 2008 (UTC)

I assume that x, y and z have to be whole numbers here. Basic strategy is to create a list of possible values for x, y and z and then test x² + y² + z² for each set of values in the list to see if it is 100. Trick is to reduce the list to a reasonable size by applying a bit of thought first. Here are some hints:

• There is no point including any value for x, y or z that is less than -10 or greater than 10 - can you see why ?
• If there is a solution with a value a for x, say, then there is another solution where x is -a - can you see why ? So you only need to include possible solutions where x, y and z are all greater than or equal to 0.
• If there is a solution, say (a, b, c), then there are also several other solutions which are "permutations" of this one; (a, c, b), (b, a, c) etc. So you only need to include possible solutions where x >= y and y >= z.

Use these hints to create a reasonably small list of possible solutions in Excel (you should find there are less than 300 possibilities) then use the IF function to test whether x² + y² + z²=100 for each one.

Not sure why you want to use Excel to solve this problem though. If you don't have to use Excel, then you might think about using a procedural programming language or a programmable calculator instead - you can write an appropriate search with about 4 or 5 lines of code. Gandalf61 (talk) 11:02, 18 August 2008 (UTC)

There's no point including negative numbers at all in your search. Because they're squared, x, y, and z can be either, so you only need to run it once, then create a congruent negative list. Matt Deres (talk) 17:08, 18 August 2008 (UTC)

All of the above will work for finding solutions to x² + y² + z² = 100 specifically, but the original poster said that that was only an example. The answer to the question depends very much on what it's an example of. Do you need an automated system that will solve equations typed in by a third party? -- BenRG (talk) 18:52, 18 August 2008 (UTC)

Office has a formula solver, just for this kind of thing. Check out microsoft's article/tutorial on it here. I've used third-party solvers before, and they gets the job done. The more complex the problem, the longer the application will take to run. ---J.S (T/C/WRE) 00:31, 19 August 2008 (UTC)

MSN, Hotmail and Safari

I have a problem which is annoying me.

I use Microsoft MSN on my apple macbook pro ( 10.4 ). When i click on the mail icon, it takes me to my hotmail inbox.

However now, every-time i click, i HAVE to re enter my password to gain access. The options to 'remember it' are there, but they dont work.

Is this Microsoft's response to weakened web security? Surely having to retype my password all the time is more of a risk? How do i stop it?86.157.85.114 (talk) 11:58, 18 August 2008 (UTC)

I have had similar problems with some sites with Safari—no matter how many times I try to get it to "remember" the password, for some reason it often just won't, even though I've got cookies enabled and etc. I don't think it's a Microsoft-specific problem, I think it has something to do with how Safari remembers cookies or sessions or whatever. It's maybe the only thing about Safari that drives me nuts on a regular basis. --98.217.8.46 (talk) 12:41, 18 August 2008 (UTC)

Here's a post and set of responses about this very problem. One possible solution suggested, but I don't know—I've never started Safari in Rosetta (why would one do that? I have no idea) personally and I still have this problem. But I'll give it a shot... --98.217.8.46 (talk) 12:47, 18 August 2008 (UTC)

"Surely having to retype my password all the time is more of a risk?" Am I missing something obvious here? Why would storing that password in your head be more of a risk than storing it in the computer where it could be used if the computer was stolen or used without your permission and/or knowledge? -- Captain Disdain (talk) 16:15, 18 August 2008 (UTC)

Yeah, storing your password in non-encrypted memory space is actually more risky then typing it in each time. Both are vulnerable to the exact same situation however. If your computer is breached, then it's lost either way. ---J.S (T/C/WRE) 00:25, 19 August 2008 (UTC)

SIS

Hi. I read the article on NTFS and came to this SIS (single instance storage) but couldn't clearly make out.Can someone explain me this a bit.Thanks —Preceding unsigned comment added by 59.103.25.107 (talk) 14:12, 18 August 2008 (UTC)

Have you read the references on Single instance storage? If so, do you have any specific questions? I'm not sure how to explain it more clearly than on the page. Gyroggearloose (talk) 20:14, 18 August 2008 (UTC)

Ok, here's an example: Lets take an e-mail server. Lets say there are a dozen people who use that e-mail server. Lets also say that one of the users chooses to send out an e-mail to everyone on the server. A e-mail server that utilizes SIS 12 exact copies of that message are going out, and instead of making 12 copies, it simply stores 1 copy of the message and adds "pointer" to that message in each person's mailbox. In this example how much data the server needs to store for that message is reduced by 91%.

When your talking about large enterprise data-servers, the savings can be even more drastic. The organization I work for has ~300 "My Documents" folders. Each folder likley has the exact same copy of our corporate Standard Operating Procedures. This file is about 10 megs. 10 megs * 300 copies = ~3gigs. If we were using the SIS the server would only be keeping one real copy and 299 pointers (basically shortcuts), saving ~2.99 gigs of storage.

I hope this helps. ---J.S (T/C/WRE) 01:03, 19 August 2008 (UTC)

Is it worth replacing Windows firewall?

A website that compares firewalls says that Comodo is the best free firewall. Not being a computer nerd/geek/etc, I wonder if its worth changing to Comodo. What worries me specifically is then when I install new programs, they may be able to update Winfows firewall automatically with no input from me, but if I use Comodo then a lot of manual tinkering with settings may be required (for existing programs too) which I am not competant to do. I have XP SP3.

Another related question please - I have just moved to XP after using a WinMe computer with a free copy of ZoneAlarm. ZoneAlarm was rather busy - you could change the setting for indivdual programs and get details of blocking done. However, Windows Firewall is completely silent - all you can do is turn it on or off. Why is this, and does it imply WF is not very good, even though my various anti-spyware and anti-virus scans have not found anything getting past it? Thanks 78.149.219.203 (talk) 14:28, 18 August 2008 (UTC)

Windows Firewall is (or at least was, on last check) rather limited in its approach. Its pretty good with unsolicited incoming requests but it totally ignores outgoing messages. As long as your system is uncompromised, Windows Firewall should suffice. If you think your machine is already compromised, you need more than Comodo Firewall. Kushal (talk) 18:12, 18 August 2008 (UTC)

Based on the leak tests I've done, Windows Firewall works great for inbound protection. The main drawback is that it doesn't provide outbound protection. That is, it doesn't prevent programs from "phoning home." Windows Vista's firewall does do this. Another drawback, as you mentioned, is that it doesn't provide feedback. Of course, it still keeps a text log that you can view to monitor activity. You can also build your own firewall by going to Start --> Run --> secpol.msc and creating your own rules from IP Security Policies on Local Computer. You can also just disable services that you don't need. Many of these listen for connections from other computers and allow worms to spread. This site tests your firewall for leaks: http://www.grc.com/. The main difference between Windows Firewall and third-party firewalls is ease-of use. Any firewall you use will often be compromised if you have a virus infection. I had Zone Alarm once and it was rendered useless by a virus infection. Now I just use Windows Firewall.--J4n56t (talk) 18:18, 18 August 2008 (UTC)

The purpose of Webdings and Wingdings

Does anyone have the answer as to why webdings and wingdings were created and what purpose do they serve? I couldn't really find that information in the articles. Thanks and cheers, 10draftsdeep (talk) 16:29, 18 August 2008 (UTC)

They don't have a lot of function now. In the prehistoric time of computers, you had limited graphics. For example, you might have 80x40 characters and 4 sprites (a sprite is an image that you can place on the screen anywhere you like). Since you primarily had to create your graphical display with characters, character sets were created that had all kinds of shapes that you could use, saving you the need to use your limited number of sprites. -- kainaw™ 17:54, 18 August 2008 (UTC)

Uniquely identified USB flash drive

Hi, I'm wondering if it's possible to uniquely identify a USB flash drive on a network - that is, if someone plugs their USB flash drive on one computer that's part of a network, and then the next day plug it into a different computer on the same network, would I be able to tell that the same flash drive was used? Does this technology exist and if it does (since I'm not very savvy on this type of technology), how common is it and where is it used (office/workplace, schools, etc)? Thanks. 141.153.214.99 (talk) 19:16, 18 August 2008 (UTC)

I'm not aware of any existing software that would permit this. I do think every USB device has a semi-unique serial number, but I could be wrong on that too. ---J.S (T/C/WRE) 00:21, 19 August 2008 (UTC)

=) Serial numbers included! Track any USB device EVER plugged into a Windows machine. USBDeview. The only automated networked ones that do this are really, really expensive (as far as the products I'm thinking of). --mboverload@ 00:23, 19 August 2008 (UTC)

I'm glad to have that verified. It explains some of XP's strange behavior with printers that I've noticed. 00:36, 19 August 2008 (UTC)

Also, they all have a volume name, which I suspect is assigned when the flash drive is formated and/or the MBR (Master Boot Record) is written. For mine it's "USB 2.0 Flash Disk USB Device", which is 29 charachters. That certainly gives you enough space to provide a volume name which is both unique and meaningful.

Address Bar Disappearing in IE

OK, I'm sure it's a simple fix and I think I've actually done it before, but the address bar has completely disappeared from the Internet Explorer that came with our computer. I don't use IE usually, just Firefox, but others in my family do use it, so I need to fix it. Thanks! --Alinnisawest(talk) 19:49, 18 August 2008 (UTC)

Try right-clicking on any of the bars at the top of IE, and you'll get a list of bars you want to view. Select "Address Bar." Laenir (talk) 20:13, 18 August 2008 (UTC)

That doesn't work; the Address Bar is supposedly there, but all that you can see of it is the word "Address". However, a friend of mine helped me out- somehow the toolbars got unlocked, the address bar got shoved over, and they got locked again. Probably some weird program glitch. But it's solved now- you just have to unlock the toolbars and drag it out. --Alinnisawest(talk) 21:08, 18 August 2008 (UTC)
