Ruby's Proposed STM

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.

Collapse OS – Why Forth?

Collapse OS' first incarnation was written in Z80 assembler. One of the first feedbacks I had after it went viral was "why not Forth?". I briefly looked at it and it didn't seem such a great choice at first, so I first dismissed it. Then, I had what alcoholics refer to as a "Moment of clarity".

Rust is a great fit for the systems-level work I’ve been doing over the last few years: often performance- and density-sensitive…

Names are not type safety

Haskell programmers spend a lot of time talking about type safety . The Haskell school of program construction advocates “capturing invariants in the type system” and “making illegal states unrepresentable,” both of which sound like compelling goals, but are rather vague on the techniques used to achieve them. Almost…

Lovely Week with Elixir

Context It’s not often I get excited about programming languages since meeting Ruby in 2015. Way before that, drowning in misery of writing university course works in Java, has pushed me away from development. Ruby’s freedom and expressiveness was what pulled me back, and its style has kept me in. I was on the lookout…
