The 2nd day of RubyKaigi - Net::HTTP Strikes Back✄
Of course, RubyKaigi was held at July 16 to 18. Sorry for my laziness.
Elise Huard - Actors on stage
Elise talked about parallel programming and actors.
Personally, I want to know about
"how to design actor
- First, you should split your problem into actors.
- And don't share mutable state with actors.
- "Supervisor" is very common pattern to build fault-tolerant system.
Eric Hodel - Writing Friendly Libraries
Eric (Dr. Brain) talked about "how to design/implement/release" friendly libraries. I remembered Microsoft Press's "Framework Design Guidelines".
Richard Huang - Use rails_best_practices to refactor your rails codes
Richard (@flyerhzm) talked about his library, rails_best_practices. It's Perl::Critic for Rails. And their internal expression is S-expression. Long live Lisp!
Wen-Tien Chang - BDD style Unit Testing
Wen (@ihower) talked about RSpec. Several years ago, I think RSpec is "just a syntax". But maybe it's time to rethink about RSpec. His talk gave good opportunity for me.
Chris talked about Mike. His fast headless-browser. I think it's really big project and V8 is not so good for embedding. I asked on the session and after the session.
- I think V8 is not good for embedding. We don't have multiple instances per process.
- Well, but V8 has context to separete their execution environment.
- Browser is really big software. Will you implement renderer?
- No. Mike doesn't need renderer.
- libxml2 can parse broken HTML, but their behavior is not documented well. Do you have a plan to support HTML5 parsing?
- Sometimes. But my first goal is finish.
Yehuda Katz - Advancing Net::HTTP
Yehuda Katz talked about Net::HTTP, asynchronous programming and reactor model. His talk was powerful. I was impressed.
Kakutani Shintaro - The Gate
Kakutani talked about his story, or history between Ruby, RubyKaigi and himself.
Sometime, my friends (especially, non-Ruby programmers) say "Ruby programmers are too enthusiastic". Well. However, several years ago, Ruby was a yet another minor language. But some people love and use. Now we have many developers, implementations, businesses and JIS X 3017!
Enthusiasm is not so bad. Do you want to use your favorite language on your business?
Really interesting and exciting. I met many people and drunk a lot. And I talked with Yehuda Katz and Matz!
