Frequent conversation: > Why don't you use AI for this task? I tried. It failed to do it better than me.. > You must be doing it wrong. Great, here's the task, try it yourself! > I see the problem. These models don't do that task well. Isn't that…

Tonight, our nation can celebrate the removal of this horrible, shallow, incompetent person from the top of the US Department of Justice. The Trump administration dumpster fire continues, but at least this idiot is gone. [contains quote post or other…

I just spent two days in mortal combat with an AI agent that convinced a user my analysis and fix for a bug was incorrect. It provided convincing descriptions of the problem and declared its fix "obvious". It was all nonsense. Your AI coding agent is…

It is a bit ironic that many folks who demanded strict static typing and who refused to even consider using dynamically-typed languages are now advocating for verifying the results of agentic coding using little more than unit tests and specifications. So…

This year is the 20th anniversary of full-time dev of JRuby. We have thousands of users, can scale apps to great levels, keep up with Ruby compat, and support customers fund my work. Meanwhile, both of my proposals for @RubyConf were rejected by…

I am excited and honored to be the keynote speaker for day 2 of #RubyKaigi 2026! My talk will explore 20 years of JRuby development, show how JRuby and CRuby have grown up together, and provide a hopeful look forward to the future of Ruby. It's been an…

Holding my breath to see how deeply the Oracle layoffs cut into the Java team. This is a really bad time to undercut critical infrastructure like the JDK. AI isn't replacing developers, it's just killing them off and leaving everything broken. …

While reviewing some LLM-heavy PRs recently I realized where my concerns lie: code written by humans is intentional and code written by an LLM is incidental. I can't easily ask the submitter's LLM context why it made certain changes and whether they are…

I could easily take Ruby with full static typing via RBS and compile it to fast static JVM code. Numeric algorithms as fast as optimized C code. I've done something similar before... it would be like Mirah but with dynamic invocation. It's just a matter of…

Excellent talk by Daniel Colson about the Ruby regex engine ("Onigmo" in CRuby, "JOni" in JRuby) with a deep dive on how it parses, compiles, and executes an expression. These kinds of talks are my jam! Loving @rbqconf.bsky.social so far!

Inspired by DragonRuby and a quick chat with @amirrajan.bsky.social at @rbqconf.bsky.social in Austin, I threw together a five-minute JRuby + Simple Directmedia Layer example using the LQJGL bindings! I'm actually shocked how easily this worked. JRuby is…

There's a ton of Open Source developers out of work right now. The same developers that maintain the libraries and runtimes you all depend upon for your apps. The same libraries and runtimes all your AI code is built upon. Hire or sponsor someone today.

This year marks the 20th anniversary of my work on JRuby! I'm looking forward to sharing that story and talking about the future with folks around the world. Being able to speak at @RubyConf and @RailsWorld would be a fitting way to celebrate 20 years. I…
