'm going to stick my neck out and say I like Perl -- so I think this is good news. However, I've always thought of Perl as a text-processing language, and In My Limited Experience, mobile phones can only fit about ten words on the screen. {on the other hand, this could simply lead to phones with bigger screens.}
There's no denying that you can write really ugly code in Perl, but you can also write beautiul code in Perl. I think some of the people who knock Perl are confusing "undisciplined" with "not anal retentive". Perl was always based around the idea of serving the end rather than the means -- it's about where you're at, rather than how you got there. It does not impose a particular style on the programmer. Thus, for any given task, there could be many, many ways to accomplish it in Perl.
They're all right.
Some will be faster than others, some will use fewer resources than others, some will look prettier then others when viewed as source. But if you don't care enough about those things to mention them in the design spec, then they don't matter.
Now, you can have your fancy object-oriented stuff, but in many ways it's overkill. For instance, if you needed to write a programme involving geometry, you could create an Angle object which would have a value assumed to be in radians and properties for its sine, cosine, tangent and representation in degrees; a Distance object which would have properties for its representation in different measuring units; and assigning a value to any property would affect the object and therefore its other properties. It might be beautiful if you like the OO concept, but it's a bit overkill if you just want to find the missing side of a triangle.
And does a "disposable" programme -- one that you will run only a few times before forgetting it forever -- really need to look pretty anyway?
As for PHP, well, it really isn't much different from Perl -- apart from always needing to put brackets around function parameters, the fact that all variables start with a $ sign whether scalar, array or hash and there is no $_. {I happen to love $_. It goes nicely with the concept of an accumulator. If you never did any assembly language, you probably won't know what I'm talking about, though}. That is hardly surprising, because the original PHP was actually written in Perl to be like a kind of subset of Perl.
Also, one of my little niggles -- and I freely admit that this is just my own opinion -- is the inability to get on with any language that uses the plus sign as the string concatenation operator while letting you freely mix string and numberic variables. {*cough* ruby *cough*} I expect "2" + 2 to equal 4, not 22. Hell, if I have to do something to my variables before I can add them, that just nullified the advantage of having freely-mixable scalar types! It might as well be a strict-typed language and barf on an expression such as "2" + 2!
As for Python - well, it's not my cup of tea {I guess you like either Perl or Python} but other people seem to have written some pretty good stuff in it, so I shan't knock it.

I usually go to nightclubs to dance and meet women, but I guess this is the Slashdot Way.
What else would a geek do in a nightclub?
Analogies don't equal equalities, they are merely somewhat analogous.

geek gets into a night club with real live women and what does he do? He programs perl. jeez

perl in a nightclub?
I do not think that word means what you think it means...

You can take the geek out of the nightclub, but you can't take the nightclub out of the geek.
I am a software developer by day, and DJ at a night club by night. The idea of programming live is really cool to me, but when I'm DJing with my computer, I'm scared to run anything other than the DJ software, because I can't have ANY lag. I do, however, write software at home to help my DJ gigs.
ChucK is a "concurrent, on-the-fly audio programming language", designed from the ground up precisely for this application: live programming of generative music.
10 PRINT CHR$(205.5+RND(1)); : GOTO 10
We are confused. What is this 'chick' you speak off?

Since you sir, have made the first hack the planet joke, you are now contractually obligated to fulfill your promise because:
1)You have met and are currently co-located with yourself.
You are the first person to make a "Hack the Planet" joke.
Therefore, it is your duty and task to kick your ass forthwith.
Yours truly,

I submitted this story last night, and it didn't get posted.
I'm just working thought the details of the venue now and I'll post a follow up to this thread once I've sorted them out. As always, we're pleased to welcome new faces. Oh, and if anyone wants, they can pop along to the pub for our monthly social tonight.

-- Sorry, I can't think of anything funny to say here.
If I may comment as the author of the article... It's not that dangerous, to be honest. I make a change, then press ctrl-x, which re-interprets the code into a dummy 'package.' If that doesn't cause compile-time errors, then it interprets the code into the live 'package.' So all I have to worry about is run-time errors, which are pretty rare. As I'm generally running a lot of scripts at the same time, it doesn't matter if one of them drops out or goes mental. In fact, it usually sounds good. I just have to fix it, then break it again, then fix it again to make it sound intentional!
Incorrect.
cogsci.princeton.edu -
Program - a sequence of instructions that a computer can interpret and execute;
The text file itself is only a script. The script + interpreter is a full program (also worth nothing that several people have whipped up programs that allows you to compile Perl scripts in to native binaries)
Guess I'm a genius for using modules from CPAN, and I didn't even know it.
I've been doing this for ages. I tried Techno but my code usually generates Blues.
Well.. bluescreens.
sorry.
My life is one big siesta in which I'm dreaming I wished my life was one big siesta.
No, if you would bother to RTFA, you would see that he is has written a multi-threadded text editor for writing perl. One thread is the editor, the other thread runs the code constantly. He writes perl code to generate musical patters. He has a system set up so that he can have multiple programmers working at the same time and it will all be in sync, you can even change the temp and all programs will sync up.
I don't know about programming on stage, but the concept of synthesizing music in perl is quite interesting.
Poke around and you can probably find MP3s of their music -- it's interesting stuff.
In addition, the two of them have written some papers & software on the programmatic generation of art, whether that be music, graphic arts, software itself, etc:
Much more of Ade's software is available from Signwave.co.uk.
