Ruby 4.0.8 Released www.ruby-lang.org/en/news/2026... This is a routine update that includes bugfixes. We recommend upgrading your Ruby version at your earliest convenience.

4.1.0 のリリースまで2か月ちょっとではあるけど、Windows の long を 64bit にするというのを滑り込みで入れることができそう。これでやっと 2GB+ の File をオープンして sha を計算するとかができるようになるかなあ。

We're have released jruby-rack 2.0.0, updating our servlet/rack bridge to the Jakarta Servlet API! We partnered with JRuby contributor Chad Wilson (github.com/chadlwilson) and the Kill Bill (killbill.io) Open Source billing and payments platform to make this happen. github.com/jruby/jruby-...

I've pushed a Rails 8.1-compatible activerecord-jdbc-adapter 81.0.pre1 for JRuby + SQLite and it can at least CRUD a scaffold app! I've provided a template here for generating a new app: (rails new -m <template>) buff.ly/uUPEfJn

Here is today's AI-generated code from me. github.com/ruby/ruby/pu... YJIT finally works on Windows (mswin), about 2x faster than the interpreter on ruby-bench's headline benchmarks.

Is it just me or does the #OneNote ink features not work great on Android tablets like the #Samsung S11? The Samsung Notes app inks very well, so it's not the S-Pen at fault. #PC

Disproportionate interactions will make things much worse.

Very interesting day of discussions at #railsworld! Introduced a few folks to JRuby, talked with some current users I did not know, even found one shop that only does JRuby. A bit sad to see folks struggling with problems JRuby solves. Hard to get the word out!

Fantastic, onward!

Like clockwork, I go to a Ruby event and meet JRuby users I never knew about! Just today, three people who used JRuby at previous jobs and two more that currently have apps in production. Gotta figure out how to reach these folks without speaking at every Ruby conference! 🤣

RubyGems 4.0.21 is out now: blog.rubygems.org/2026/09/16/4... This release is regular bug fix release. Bundler prevent to update beta version with `bundle update --bundler` now.

Great advice from Jethro Tull for when you wonder if you're too old. "You're never too old for rock n' roll If you're too young to die" #music #JethroTull #LifeAdvice

My own experiments using AI for JRuby work have been mixed, but I can report a great success: contributions from people that never would have attempted such things before, like Ruby core devs and Rubyists with no JVM experience. So many PRs lately! github.com/jruby/jruby

Pollution levels in London after 10 years of advancing sustainable transport.

I recently had a nice chat on the Technology for Humans podcast about the past, present and future of JRuby... including some myth debunking that might help Ruby folks look past the "J" to the amazing tech underneath. Check out the video here: www.youtube.com/watch?v=Q9Sq...

New York’s congestion pricing program has resulted in a statistically significant reduction in travel times for EMS vehicles

The great thing with going to watch a #Musical is that the band always plays the songs you know and could sing along to (but the bad thing is that you're not allowed to!) #theatre

AWS: DuckDB will provide 'connective tissue' across the data estate

Narrator: Yes, it was.

I've waited 33 years from when I heard it first as a plucky 16 year-old to watch #JesusChristSuperstar performed live. No more! That ends tonight at the Marina Bay Sands theatre in #Singapore. Too bad my 9 y.o. isn't allowed in. #Musical #Theatre

I guess it's a really bad idea to watch #TimMinchin as Judas before going to watch a live production of #AndreLloydWeber & #TimRice's #JesusChristSuperstar in #Singapore? The Arena Tour 2012 cast was so very good - wish I had been able to see that live. #Musical #Theatre

RubyGems and Bundler now pass their full test suites with RUBY_BOX=1. I am working toward Ruby 4.1 so that Ruby::Box is stable enough for real projects. bugs.ruby-lang.org/issues/22275

If you want to explore, the code is here: gist.github.com/tenderlove/0... The trick is that the multi-assign returns an array, and it can't be elided because initialize returns it (even though `new` ignores it)

I was unable to make it to ISA this year but it is finally here! Huge thanks to the Global International Relations Section! @isanet.bsky.social @yalepress.bsky.social

If you bought the ebook of Programming Ruby 4 you should be getting an email with a final beta before production. Also, if you have an ebook of Programming Ruby 3.3, you should also be getting an email with an update.

Cited on in the SQLite docs. That's pretty cool.

Rails + AI models, which to use? Along with the Rails Foundation we benchmarked the performance of eight AI models against atomic tasks and evals. We found that Opus 4.5 is slightly more accurate and affordable than Fable, but slower. Kimi K3 gives you similar results for almost half the price. 🧵

In case anyone still runs Rails 7.2.x this is the sign to rush the upgrade. I assume that version is now not supported anymore. Source: rubyonrails.org/maintenance

Is there now an easy (or slightly complicated) way to move #Microsoft #Whiteboard documents from one Outlook/ Live account to an M365 account? One of the good things with "desktop / files" is this ability to just cut and paste the files from one place to the other.

What does this do? Does it mean I can use my LG Magic Remote from the TV as a mouse for my phone or tablet? #Samsung #LGTV #Tech

After you take a snip with the Snipping Tool in #Windows11, you can right click on the window in the taskbar and select to take a time delayed screenshot - it used to be in the snipping tool UI when you started it and was convenient... but at least it is some place #Tech

The fact that you can just use the S-Pen from the #S24Ultra on the #Samsung #S11 Tablet feels magical, and like a game changer in some ways since my phone is always with me anyway! technology

Got my copy 😍 The 2nd edition contains chapters on concurrency (incl. Ractors) static typing (RBS, Sorbet) and code optimization (profiling, JIT) – straight from a Ruby committer. I admire Jeremy Evans for his dedication, though being a technical reviewer isn’t the easiest either 😅

Postgres 18. uuidv7() applied as a new PK column default. Inserts at 2-10K calls/minute. Inserts total time dropped from 1 millisecond to around 50 microseconds, about ~20x faster. Thanks to Postgres developers for this work which enables PK index maintenance to be much more efficient!
