Ruby Central forcibly removed the people who built RubyGems for over a decade, replacing them with a 'Director of Open Source' whose last Ruby code was a conference tutorial in 2010. This is the anatomy of a hostile takeover disguised as 'strengthening stewardship.'| Seuros Blog
Do you run Rails or pure Ruby applications on Heroku? If so, it's important to be aware of upcoming end-of-life (EOL) dates for both your stack and your Ruby version. The Heroku-20 stack, built on Ubuntu 20.04 LTS, will reach EOL for standard support in April 2025. Ruby 2.7 has already passed its EOL, meaning it's no longer receiving critical security updates. Continuing to run your app with either an outdated Ruby version or an unsupported Heroku stack exposes your application to increasing ...| Heroku

I’ve spent 15 years of my life working on Bundler. When I introduce myself, people say “oh, the Bundler guy?”, and I am forced to agree. I didn’t come up with the original idea for Bundler (that was Yehuda). I also didn’t work on the first six months worth of prototypes. That was all Carl and Yehuda together, back when “Carlhuda” was a super-prolific author of Ruby libraries, including most of the work to modularize Rails for version 3.| André.Arko.net
JDK 25 is the newest LTS release since JDK 21, and it ships with a gaggle of amazing VM-level features.

It’s a great idea to make your database and application validations match. If you have validates :name, presence: true in your model, you should pair it with a not null database constraint. Unique validations should be paired with a UNIQUE database index.| Boring Rails: Skip the bullshit and ship fast |

For the last ten years or so of working on Bundler, I’ve had a wish rattling around: I want a better dependency manager. It doesn’t just manage your gems, it manages your ruby versions, too. It doesn’t just manage your ruby versions, it installs pre-compiled rubies so you don’t have to wait for ruby to compile from source every time. And more than all of that, it makes it completely trivial to run any script or tool written in ruby, even if that script or tool needs a different ruby t...| André.Arko.net
