Just wanted to say that the authors libraries, especially ROM [0], are incredible and have played a huge influence on me as a developer. I learned a lot using and diving through the code.

Better gems. dry-rb, ROM, and Hanami are doing interesting stuff. I also hear web_pipe is popular?
10 Years of Open Source
2 projects | dev.to | 4 Jun 2021

This is exactly how I ended up contributing to DataMapper, then joining the core team, then releasing Virtus, then working on DataMapper 2.0, then turning it into rom-rb, then joining dry-rb and building 1.25 library / month on average for about 2 years or so to eventually join Hanami team...and, yeah, it's been kinda nuts now when I look back.

ArrayBuffer and DataView classes for ruby
2 projects | /r/ruby | 30 Apr 2022

One option to solve my problem was to use nio4r's ByteBuffer class, but it felt weird to have to use an I/O gem just for its ByteBuffer class (although I was using the gem already anyway). I mean, it'd probably have worked.
