Both DSPy and (especially) GEPA are currently severely under hyped in the AI context engineering world
Oh! This is very exciting! andre.arko.net/2025/08/25/rv-…
Introducing Tidewave Web for Rails and Phoenix: a coding agent that runs in the browser alongside your web application, with full page and code context. Tidewave deeply integrates with your stack, from the database to the UI, making AI development more seamless and efficient.
Here's the concluding section of my write-up of the new OpenAI open weights models - they're really impressive, and I think they hold their own (or even beat) the models we've seen come out of the various Chinese AI labs over the past few months
Regarding agent-context, I wrote a specification github.com/ioquatix/agent… I think `CLAUD.md` and `.cursor/rules` are anti-patterns - we should have an open specification for sharing context between packages and projects.
I like this take by @KentBeck on how AI-assisted programming changes the balance of which skills are most important
Great reminder of how engineers should provide estimates to their managers: no hard dates, only a range, a probability distribution, with optimistic and pessimistic ETAs. And you can only promise to update your ETAs daily

Take advantage of `Array#inquiry` for more expressive and idiomatic code! 😊 For example, here we use it to simplify feature toggling by avoiding constantly writing `include?('feature_name')`. #rubyonrails #activesupport
I just opened a new PR to ohmyzsh to fix the "chruby" command (and its "rubies" alias) output and hopefully speed up the whole loading process a bit for the chruby plugin: github.com/ohmyzsh/ohmyzs…
I'll say it again, if you're not using jemalloc on your Ruby web application, you're missing out on saving ~50% of your memory usage. Here's yet another graph of us doing that for a client this week.
A bit outdated but still great article on how to work with dates in Rails and not only nandovieira.com/working-with-d…
One of the best productivity tips I have ever learned at Framer (from @eelco) is: Whenever you want to ask a teammate for help, don’t DM them. Instead, always post your question in a channel (and cc them).
Rails 8.0: #NOBUILD, #NOPAAS, all-in on SQLite as a production database option with jobs, cache, and cable, new authentication generator, and so much more! Final release is out 🎉 rubyonrails.org/2024/11/7/rail…
Kamal Handbook, 2nd edition for Kamal 2 is now available as a beta release🎉 Kamal 2 is even better than Kamal 1: - automatic SSL/TLS for small apps - multiple apps on one server - faster deploys for more servers Thanks to everyone for the support 🙏 kamalmanual.com/handbook/
This is why I love Cloudflare. Owning your own hardware doesn't mean you can't contract with a bodyguard. We do that and it saved our bacon a few months ago when we were attacked.

Because @fxn doesn't stop at simple explanations, I went to dig into why this benchmark give the opposite results of what one would expect 🧵
Hello, do you run a Rails application and for some reason don't use jemalloc? Clear your calendar for the next hour, and install jemalloc in production. Here's my latest retainer client saving almost 50% of their memory usage by making a 3 line change to use jemalloc.
The effect of switching id for new records from UUID v4 to UUID v7 on INSERT to a 24 GB PostgreSQL table with 116M rows.
These 94 lines of code are everything that is needed to train a neural network. Everything else is just efficiency. This is my earlier project Micrograd. It implements a scalar-valued auto-grad engine. You start with some numbers at the leafs (usually the input data and the…
New open source OCR model just dropped! This one by Microsoft features the best text recognition I've seen in any open model and performs admirably on handwriting. It also handles a diverse range of vision tasks. You can play with it here: huggingface.co/spaces/gokaygo…
