Looking at the memory map of a Go 1.27 program on Linux
Writing code isn't the bottleneck anymore, reading is
This week I was working on one non-critical feature that seemed simple at first sight. 50k lines of code later, it seemed to work as expected. In a side project, or a service where “nobody will be upset if it’s dead and kills everything around”, it would be read...
Code like a pirate with AI
Will AI coding agents pirate all our jobs? Not if we take back control, using my six-step PIRATE workflow for shipboard discipline.
Relative velocity and closing speed
In Physics simulations or game engines it’s sometimes useful to determine the speed with which two objects are approaching each other. This post will discuss the concept of closing speed, which is the normal component of the relative velocity of two objects. Relative velocity...

Fake Clocks, Real Guarantees: Inside Go's synctest
The first time I reached for testing/synctest, I assumed it was a sleep helper with better manners. The public API is small enough to support that assumption: synctest.Test(t, func(t *testing.T) { ... }) synctest.Wait() synctest.Sleep(d) // new in Go 1.27 Three functions, one obv...

Solving my problem with the Emacs Lisp byte compilation checker
Compute
I said that it’s likely that AI layers commoditize like everything else has. The harness, the planning loop, tools use patterns, the memory files, the protocols, context management, etc. I have watched ideas in this layer go from novel to table stakes in a few months. Every...
