Stamping Out Overflow Checks in Ruby
Someone on Reddit asked if it was possible to turn off overflow checking on integer arithmetic in Ruby. They said that they could guarantee that their arithmetic would not overflow, and therefore they’d like to not pay the cost for a pointless check. As several people said in the thread, this isn’t possible in the standard implementation of Ruby, MRI, but it is possible and safe in TruffleRuby. An

The Future Shape of Ruby Objects
These are the notes for a talk I gave at RubyKaigi 2021, which is why they’re written as if we were talking and going through some slides and code together. Hello I’m Chris Seaton. I’m a Senior Staff Engineer at Shopify where I’m working on Ruby performance. I’m the founder of TruffleRuby, which is a very highly optimizing implementation of Ruby. I also maintain The Ruby Bibliography at rubybib.or

Context on STM in Ruby
There’s a proposal to add Software Transactional Memory, or STM, to the Ruby programming language. This is part of a wider effort to add better support for concurrency and parallelism in Ruby, and in particular the idea of ractors. A concept has been proposed and implemented by Koichi Sasada. An animation of the algorithm we're going to use as an example of STM - we'll explain this later on This a
