- My first community attending is for "Generation 1991".

- In RubyKaigi2011, I proposed String#prepend method, and accepted!
- Now I have refined the parallel execution of Ruby-test.
- Why only few junior highschool or highschool students are attending to tthe community?
- Let's try on and join us

- That's Joyful!
- I made a Ruby subcommittee in my company, and I held some ruby events in there.
- Some people start to drop out, why?
- There are programmers not being fun with programming, in enterprise domain.
- I mistake a theme: series event, abstract theme
- So I refine: ont time event, concrete theme

- Parallel world of CRuby's GC
Video (Japanese)- by nari
- CRuby is running on 1-core.
- GC is "mark and sweep".
- Parallelization
- CRuby is still running on 1-core.
- But GC is not.
- Parallel marking
- Task steeling
- Lock free
- sweep with pop_top() and pop_bottom()
- Many threads call pop_top() and pop_bottom()
- Race Condition occurs in pop_bottom()when element size of deq is 1.
