Today I checked my gmail E-mail and saw that my friend sent me a link to a hilarious videoclip of "A Finite Simple Group (of Order Two) by the Klein Four Group, which are a mathematically-inclined a-capella group. I liked it so much that I decided to send it to the members of my long-forgotten Jokes Distribution List using my KDE mail account.

Well, the problem was that it really was long-forgotten as KAddressbook did not list it or any other distribution list I had prepared in its previous incarnations. So I decided to investigate. I created a new distribution list with a few members and saved it. When inspecting the KAddressbook directory (~/.kde/share/apps/kabc/) I found it no longer stored them in the file distlists but rather inside std.vcf in specially-formatted records. So I whipped up a quick Perl script to convert it to the new format, which worked after a tweak or two. After restarting kmail, I was able to see my distribution lists' again, and could send my mail.

Since the video had no sub-titles and one of the people on the list is deaf, I googled for the lyrics for this song and found them, and included a link to them in my email.

So far so good. But then I decided I like the song so much that I wanted to listen to it using Amarok (my music player) from time to time. So I moved the .flv (Flash Video) file I had downloaded from the Youtube link using youtube-dl, to my mp3's directory and tried to enqueue it using Amarok. It didn't work, as Amarok complained it lacked an audio channel. Trying to play it in xine, which is the Amarok media-playing backend I'm using didn't work as well. It seemed like a xine limitation.

Then I remembered this article about converting from .flv to DivX or Xvid that I saw on Linux.com. I followed its instructions and ran the script. It did a whole lot of stuff, but I couldn't find the file. As it turned out, my filename contained whitespace characters, which broke the script and caused it to output to the file .avi (which is normally invisible). To fix it I had to change:

 "`basename $1 .flv`.avi"
 "`basename "$1" .flv`.avi"

Which made it work. Now Amarok could play the AVI file, but not rewind and fast-forward it. Possibly another limitation.

All this time I was talking on IRC. I joined #kde in order to resolve my distribution list problem, and there I helped a few people. While I was in the neighbourhood, I decided to join #math and let them know of the song. Someone there recognised it, and gave me the link to the Klein Four Group's. There I found audios in mp3's formats and videos in Windows Media's .wmv format for many of their songs (including "Finite Simple Group (of Order Two)"). So in this case, I didn't have had to bother with flv2avi.sh. (Albeit it may come in handy some other time).

So now the Jews have Joy and Aura, and I can listen to the song comfortably. I listened to it at least 5 times today. I'd also like to check their other recordings.

P.S: when I said that "C++ is complex, complexified and complexifying", I thought the verb "complexify" did not really exist, but it does, and it appears in this song.

that is the only word i can describe ALL of your writing.

you always try to find a topic title which would actually get people interested. and go a long way picking topics. but what you do in fact is find excuses to say how great you are, what kind of lame-half-assed script you wrote or just how good you are with Os/programing in general.

and when someone say something. you go on personal. (my favorite part is when you used to correct people's grammar and spelling instead of actually responding with something you didn't just read off a man. or in some other reference.
some of your "real" answers actually sound as if you just damn googled them.

and don't get me started about the Hackers-Il group where it turned to your personal "i can write whatever the hell i wan / all praise Shlomi".
you single handedly drove most of the members who left to leave.

and I'm cutting this here because i don't think its worth spending any time over the one minuet i already wasted on this

I don't know neither you nor the anonymous guy that replied, but hey... someone REALLY hates your guts :D

Anyway, this song is one of my favorite, but I cannot find any studio recordings of it (you mentioned that there were audio versions at their website, but all links are broken)...

I know it's been about 4 years ago, but if you have an audio file of studio recording of this song, I would very much appreciate it if you uploaded or link it here.

All the best and...
Watch out from the sniper! ;)

Re: man...

First of all, here are the two recordings that I have of the Klein Four Group - one of them is an .wmv and the other (the "Finite Simple Group" one) is an .mp3. They are not studio recordings, but they are of high quality and you should check them out to see if they are what you want.

Regarding the previous anonymous poster ("spam... that is the only word i can describe ALL of your writing."), yes, I'm aware that he really hates me. My blogs have received their share of anonymous hate comments, but lately, the situation seems to have become much better, and I hope it will persist. I still reserve the right to delete anonymous comments that I find especially flammatory and annoying.

In any case, I hope you enjoy my uploads (in the link).
