The past few days i looked at ways could use my Logitech Quickcam Pro 5000 USB Webcamera. Skype 2 did a nice job using all its features, including to my surprise, the integrated microphone.

Installing the driver/module was a piece of cake, goto http://linux-uvc.berlios.de/ pickup the latest stable and do the usual compile&install, then load the module.

You may need to reboot at this point.

Now some testing was in order, pickup the luvcview viewer (you need libsdl-dev packages to compile). Make it, then you can run it just by ./luvcview ( if you have more video devices installed, you may need to set the according device it needs to read, see readme ) or install it with a quick ’sudo cp luvcview /usr/local/bin/’ for later reuse.

Ok, i got the cam running, i can see myself, and i can chat to people with Skype, what next ? (If it didnt work for you at this stage, the next steps wont help you.)

(more…)

As the last post was about the size of bash.org, this one is about xkcd, the famous comic site, a simple set of scripts and you get the whole set and a few stats:
Use script wisely, it’s a strain on servers.

#!/bin/bash
echo "Downloading 395 pages."
for i in `seq 1 395`;
do
	if [ -s "xkcd/$i" ]; then
		continue
	else
		echo -n "`date +%H:%M:%S`: Trying $i ..."
		lynx --source "http://xkcd.com/$i" > "xkcd/$i"
		echo -n " Done. Image:.. "
		wget -q -p "comics" -nH "http://imgs.xkcd.com/comics/"`awk 'BEGIN{FS="<img src=\"http://imgs.xkcd.com/comics/";RS="\" title="}/<img/{print $2}' "xkcd/$i"`
		echo " Done."
		sleep 2s
	fi
done
echo "All done."

This piece of code does sometihng special, it takes the name of the image and uses wget to download it.

$n=1;
$vse=0;
while ($n < 410) {
	unset ($fajl);
	$fajl=file_get_contents("original/".$n);

	preg_match_all("|
<p class=\"quote\">(.*)<b>#(.*)</b>(.*)
<p class=\"qt\">(.*)

|Us", $fajl, $out);
	$i=0;
	while (isset($out[0][$i])) {
		echo '('.$out[2][$i].")\n".$out[4][$i]."\n";
		echo $out[2][$i]."\n".$out[4][$i]."\n";
		$i++;
		$vse++;
	}
	$n++;
}
echo "\n(".$vse.")";

And a parser that makes the final big file of everything, coincidentally also making the comments easy to read.
Comics make the most part of the download, with ~22 MB.

And as usual, the download link: LINK (22mb), or email me for the data.

I spent the last few hours on a simple question, how large is the worlds largest irc quote database (bash.org) ?
Thinking specifically of the quotes themselves.

So first i had to get them all, a simple bash script was sufficient.

#!/bin/bash
echo "Downloading 409 pages."
for i in `seq 1 409`;
do
if [ -s "original/$i" ]; then
continue
else
echo -n "`date +%H:%M:%S`: Trying $i ..."
lynx --source "http://www.bash.org/?browse=$i" > "original/$i"
echo "Done."
sleep 10s
fi
done
echo "All done."

Please, do not use that script, it is a strain on the bash servers, instead you can grab the original files at the end of the article.
After a couple of hours that was done, and i had my next script ready as well;

$n=1;
$vse=0;
while ($n < 410) {
unset ($fajl);
$fajl=file_get_contents("original/".$n);

preg_match_all("|
(.*)#(.*)(.*)
(.*)|Us", $fajl, $out);
$i=0;
while (isset($out[0][$i])) {
echo '('.$out[2][$i].")\n".$out[4][$i]."\n";
echo $out[2][$i]."\n".$out[4][$i]."\n";
$i++;
$vse++;
}
$n++;
}
echo "\n(".$vse.")";

The last line is to make sure i got all of them, 20440 at the time.
Ran it with shell, and piped to “final”: php parser.php > final

So, the conclusion was, the size of bash.org is ~5 MB
This are the files if you want them: link. (or email me)
