Ruby's predicate (?) and bang (!) methods make code speak for itself:

empty? → returns boolean
sort! → mutates, danger ahead

vs:

isEmpty() → less expressive
sortInPlace() → verbose

Language design choices like this make Ruby a joy to write.

I read a lot of books, always have. Shantaram by Gregory David Roberts is the best novel I’ve read in decades, possibly ever.

"Love is knowing you're right and pretending you're wrong because it just ain't worth it." @mattruby.bsky.social

Flip side is not wanting to do pretend anymore is a sure sign you're falling out of love with someone.

I devote a chapter of my book Patterns of Application Develoment Using AI to this topic.
The future of AI is models that generate graphical interfaces. Instead of the linear, low-bandwidth metaphor of conversation, models will represent themselves to us as computers: rich visuals, direct manipulation, and instant feedback.

Today's huge OpenAI outage taught me an important lesson about Sidekiq queues. Just because jobs are handled at a low priority doesn't mean that they can't bring processing down to a crawl. Segregate critical but potentially laggy jobs into queues that run on _their own_ Sidekiq process.

Codebuff is still my favorite AI pair programmer by a long shot (better than Codeium's Windsurf Cascade and Cursor's Composer). It rocks Ruby on Rails features, refactoring and Rspec tests!

Do I know any experienced full-stack engineers that love Next.JS, Ruby on Rails, _and_ Swift? I might have a job lead for you...

Kudos to @buster.bsky.social and the 750words team for a beautiful rewrite of their journaling system. I'm kind of late to the v2 party but wanted to give them some love and publicity anyway. (I've been a customer for almost 15 years at this point!)

About a week into being forced to re-learn React (this time with Typescript) so that I can integrate some Rails-based API code with a Next.JS front end. It's been painful and everything seems way overcomplicated compared to how beautiful and easy it could be done in full-stack Rails.

Losing interest in Twitter so will try to hang out here more. For starters, let me plug my new programming book now on Amazon
