After a year hiatus, my series on all things Ruby concurrency is back! This post digs into the interrupt mechanism in Ruby threads. The interrupts revolve around bit masks, so it's got some Ruby bit work too! Expect more regular updates from now on 💃 Read it at the link below!

This is a must-read for learning how scalable vector indexes work. @vmg is one of the best writers in the tech world.

Vitess databases on PlanetScale support sophisticated vector search. We've published a deep-dive by @vmg on how we built this for MySQL in a way that is scalable, performant, and ACID-compliant.

If you're interested in open source and don’t know how to get started, I wrote a series of articles on the AppSignal blog to help you learn how to read and understand the source code of Rails Engines. Here is the first article 🎉👇

Tuesday morning is a good time for open source. At JetRockets we use @rails @tailwindcss @ViewComponent, and StimulusJS as our default front-end stack. Time to contribute back. We created a sample Rails 8 app with the collection of UI elements we use daily, pushed it to GitHub,…

The iconic Google Bigtable paper. On the technical side it left me wanting more. I *loved* the last few pages though. Performance analysis and real-world use cases for Google Analytics, Maps, and personalized search. More orgs should talk about their internal tech and scale!

The AI Engineering book from @chipro is GOAT. But I didn't realize its repo has a goldmine .md of the resources she used to write the book. These are papers and blogs you can use to learn about making LLM apps, prompt engineering, fine-tuning, RAG, and much more.

Proxmox is such a great tool for testing Omarchy and Omakub releases. I just have a bunch of snapshots at different versions and times that I can upgrade to verify that stuff works. All powered by my lovely Minisforum A2 home server and accessed via @tailscale from wherever!
