This post was originally given as a talk for Friendly.rb and Kaigi on Rails. The slides are also available. Between Litestack and the Rails 8 trifecta of Solid Cable, Solid Cache, and Solid Queue, it’s easier than ever to spin up a Rails app that doesn’t need a database service, or a redis service, or a file storage…
Certain tasks, and their complexity, change how impactful an interruption is. Research also discovers a disconnect between perception and physiological data.
I've been learning a lot about low level programming languages lately, and for a long time there has been one thing that has interested me: SIMD (or 'single ins…
We’re happy to announce a new release of ClojureScript. If you’re an existing user of ClojureScript please read over the following release notes carefully.

Imagine you close your laptop lid to put it to sleep, but instead of pausing, it reboots. Not every time, just often enough to be infuriating. You try to save your work, but the machine decides to start over.
LLM models are plateauing, but true AGI isn't about scaling the next breakthrough model—it's about engineering the right context, memory, and workflow systems. AGI is fundamentally a systems engineering problem, not a model training problem.
How to start really getting Ruby, especially blocks.
Yet another programming blog. Thoughts on software and related misadventures.
People think they can use Fine-Tune for Knowledge Injection. People are Wrong
And by LLMS I mean: (L)ots of (L)ittle ht(M)l page(S). I recently shipped some updates to my blog. Through the design/development process, I had some insights…
False sharing, AoS vs SoA, random access, branch prediction: re-measured with go test -bench on two machines. Some claims held, some didn't.

Reproduce Deepseek R1 „aha moment“ and train an open model using reinforcement learning trying to teach it self-verification and search abilities all on its own to solve the Countdown Game.
We rolled out Go 1.24 and saw a memory regression. Here’s how we dug into system metrics, uncovered a bug in the runtime allocator, and worked with the Go team to help fix it.
Stephen Wolfram discusses understanding proofs discovered using automated theorem proving. Based on Wolfram’s proof of the simplest axioms of logic of Boolean algebra.
