RubyKaigi 2018 Review – conference in a nutshell - Closer to Code
RubyKaigi 2018 has ended, but the excitement is still fresh. After 25 hours in planes, trains, buses, and cabs we’re finally home.

Rubyists: Just use double-quoted strings. | Viget
TL;DR If you've written Ruby, you've heard it before: Use single quoted strings unless you need string interpolation. It makes sense, right? When I instantiate strings using double quotes, the Ruby intepreter has to do extra work to figure out if it needs to perform interpolation. Since extra work means reduced performance, it seems reasonable to avoid double-quoted instantiation unless it's a nec
Is there a performance gain in using single quotes vs double quotes in ruby?
Do you know if using double quotes instead of single quotes in ruby decreases performance in any meaningful way in ruby 1.8 and 1.9. so if I type question = 'my question' is it faster than question = "my question" I imagine that ruby tries to figure out if something needs to be evaluated when it encounters double quotes and probably spends some cycles doing just that.

How is Ruby Different in Japan? — Engineering Blog
I've had a few conversations recently where I say things like, "the Japanese Ruby community uses Ruby for different things than in America"... and I get blank stares. Specifically, I mention that America is very centered on Rails and web apps with Ruby. No surprise, right? "But then," people ask, "if they're not using Ruby for Rails, what do they do with it?" And why does anybody care? For the sam
