Shibuya.pm will have its 9th technical meeting and the topic of the meeting is XS. No, I'm not joking and all the talks are somehow about XSUB stuff. Let me quote some talks:
PerlMachine is a crazy project that is a minimal linux kernel that is designed solely to run perl. He reimplement most perl built-in functions in XSUBs and link them directly to the kernel functions he made. So I assume it's like lispmachine for Perl.
It is quite exciting that PerlMachine and Ruby.pm talks are done by students from University of Tsukuba. Perl has a bright future!
I can't make it to the meeting because I'm back here in San Francisco (so this is the first Shibuya.pm meeting that I can't attend) but I'm sure there will be ustream. Looking forward to it!
