RuboCop 1.89: Project-Wide Analysis with Rubydex
RuboCop 1.89 is out, and it comes with the usual assortment of new cops and bug fixes. But there’s one theme running through this release that I’m particularly excited about, and that’s what I want to...

I used to a be a huge fan of the arcade "Mortal Kombat" games as a kid, and even after all those years I enjoy watching the MK movies, no matter how bad they might be. Today I watched back to back the new MK 1 & 2 movies. Now I'm wondering if I should also re-watch the originals... 😅
The most important lesson I learned from "The Bear" is that Eddie Vedder (of Pearl Jam fame) is actually for Chicago. I spent my entire life thinking he was from Seattle... He has a couple of awesome songs in the show.
I wrote an update on the dispute with Ruby Central over Bundler and RubyGems. I'm sad it's reached this point, especially since Ruby Central's conferences are a big part of what convinced me to join the Ruby community back in the day. andre.arko.net/2026/07/30/rub…
Ruby Central's Destructive Legacy
At conferences and meetups, and in conversations online, many Ruby developers have asked me about Ruby Central and my disagreement with them. This post is my attempt to answer the questions I’ve been getting over and over, covering: 1) what is Ruby Central doing now? 2) has the dispute over Bundler…

I just released Insta, a new snapshot testing library for Ruby, live at RubyConf in Las Vegas! Extracted from Herb's test suite and inspired by @mitsuhiko.at's fantastic insta library for Rust. `gem "insta"`

We're only a few days from the release of CIDER 2.0 (see metaredux.com/posts/2026/0...), so I'd appreciate it if you played with the development version a bit and reported any issues you discover. Right now it seems the release will happen on Monday/Tuesday next week. 🤞 #Clojure #Emacs
CIDER 2.0 is Brewing…
Normally I write these posts after a CIDER release is out, with the smug satisfaction of someone who has already tagged the version and updated the changelog. Today I’m flipping the script a little: t...

Argentina - Egypt 0:2 with only 20 more minutes to go. I didn't see this coming, but that's the magic of the World Cup, right? Of course, I'm not watching the match as it's the second week of Wimbledon and one has to prioritize. ;-)
Винаги се впечатлявам от хората, които ходят до Халкидики или Тасос през седмица през лятото. На мен 6-7 часа каране и без друго са ми доста уморителни, а като вкараме и доста трафик, лошите пътища и някое-друго задръстване тоя тип пътувания ми идват тегави. Но видимо за много хора не е така.
I got to play a bit with the much hyped Fable 5 model this week, but I don't really understand why so many people were raving about it. Perhaps I didn't leverage it to the fullest extent, but the outcomes seemed similar to what I got with Opus 4.8, but the token usage seemed much higher (2-3x).
In case you missed the memo - Projectile 3.0 (the "original"/vintage #Emacs project management extension) is out with many improvements and a few bigger changes. You can read more about what's new and different here metaredux.com/posts/2026/0... I hope you’ll find some of them to your liking!
Projectile 3.0
Projectile 3.0 is finally out, and it’s a big one - easily the biggest release in years. There’s a nice reason for that: this year Projectile turns 15.1 It all started back in the summer of 2011, simp...

I haven't binged any TV show in quite a while. Most of the shows I used to like early on have dropped down in quality a lot (e.g. The Bear, Euphoria, Industry, etc) and I don't see anything particularly interesting in the new shows. Any you'd recommend? P.S. Perhaps I should read more books? :D

I used to be a huge football (soccer) fan, but now I don't care about the World Cup at all. So far I haven't seen a single game, but perhaps this will change somewhere around the quarter-finals... 😂 I barely follow/watch football in general these days. Tennis is the only sport I still enjoy a lot.

Important development for the #Ruby ecosystem blog.rubygems.org/2026/06/03/c... One also has to wonder how come supply-chain attacks became so much more common and devastating in recent months... ;-)
Cool down before you install: give new gems a few days to be vetted
Most supply-chain attacks against RubyGems exploit a narrow window: an account is compromised, a malicious version ships, and any bundle install in the minutes that follow resolves straight to it. ...

Had a blast a #RubyConfAT 🙌 The combination of technical talks and classical music was unique 🎹 Lots of AI inspiration. @batsov.net's talk about Rubocop 2.0 reminded me how special our community is. I got to meet @marcoroth.dev in person and geek out about Herb and Ruby tooling. Very fulfilling ❤️
My last hot take - #RubyConfAT was amazing and I’m leaving it full of positive energy and inspiration! The future of the #Ruby community looks as bright as ever! Huge kudos to @hansschnedlitz.com, @misabegovic.bsky.social and everyone else who was part of this beautiful festival of passion and love
