in reply to Any interesting philosophy of programming articles to recommend?
Some neat movies of PJ are also available. I realize this is probably not what you seek, but please note that Perl plays to our linguistic talents, while some people are better at spatial reasoning than at thinking in words. It is also evident from the above essay on concurrency that it is possible to build a system which by its architecture resolves whole genres of headsplitting problems. And Perl newbies may pick up the English-sounding commands relatively easily but might prefer explaining a complex datastructure with a pen and paper instead of dealing with all the brackets, parentheses, and diacritical marks you need to build and access them in Perl.
I think there are similar fault lines in thinking inside real-world software projects as well, not just in terms of technical expertise either. As the Mob Software article suggests, the pressures they generate lead organizations to latch onto fashionable methodologies.. perhaps you will find a solution?..

There's also Max from Opcode Systems. I've played with it (a visual programming tool that lets you do anything with midi and serial cables), a friend was able to turn seismographic live from California into body-shaking sonics at a Tokyo art museum. The interface (which animates as it runs, and can be pulled and tweaked on the fly) is very good for technical artists.
