in reply to (OT) Programming languages for multicore computers

I'd say multi-core programming isn't just the future, it's the present. It's been at least a couple years since anything I wrote ran on a machine with just one core. Usually the kind of parallelism I need is easy to get - Apache/mod_perl runs multiple copies of my code and on the backend MySQL runs multiple threads to service them. For slightly harder problems requiring some coordination between processes I use Parallel::ForkManager and pipes with IO::Select.

I'm very sweet on Erlang, but whether it's right for you is something only you can judge. You might get to market faster by leaning on the built-in parallel features or you might get bogged down in the learning curve of a new environment. I think a lot depends on just how much parallelism you need to exploit - if we're talking about dual and quad core machines then some fork()ing Perl code is probably good enough. If you're deploying on a cluster of several hundred 32-core machines, well, you might need more management ifrastructure and going with a pre-built system may be a better idea than rolling your own.

[marto]: hopefully you guys are also well :)
[Corion]: marto: Yeah - I'm looking for a week off in a week, even if it'll be a trip to Amsterdam ;)
[Discipulus]: oh thanks, i'm always at well as the ratchet or bucket
[Corion]: But I'm slowly starting to get into programming again - yesterday I translated my talk for YAPC::E (in Amsterdam) to English, and decided to put my Jekyll-clone to rest for the time being
[Corion]: Discipulus++ # being well is like being earnest
[marto]: hopefully next year I'll be in a position to go to Perly things in Europe :)
[Corion]: Maybe I'll use the Real Jekyll a bit to get a feel for how it actually works, and to get annoyed by it ;)
[Corion]: marto: That would be cool :) There is no kids care at Perly events unfortunately, so it's not entirely family friendly
[Corion]: I think I should define a set of (say) five projects through which I rotate from time to time, just to prevent myself from being bored/annoyed by the problems they get stuck in ;)
[marto]: Corion, not bringing the kids would make it ideal :P
