In GNU Emacs, I should remember that the basics still work
Lifecycle management in Go tests
Unlike pytest or JUnit, Go’s standard testing framework doesn’t give you as many knobs for tuning the lifecycle of your tests. By lifecycle I mean the usual setup and teardown hooks or fixtures that are common in other languages. I think this is a good thing because y...

Elephants for breakfast: testing the untestable in Rust
How do you test functions that can’t be tested? That’s easy: you don’t! Instead, you use the magic function technique to break down the elephants—excuse me, functions—into smaller bites that you can test.
You can only customize GNU Emacs so far due to primitives
Implementing Forth in Go and C
I first ran into Forth about 20 years ago when reading a book about designing embedded hardware. The reason I got the book back then was to actually learn more about the HW aspects, so having skimmed the Forth chapter I just registered an "oh, this is neat" mental note...

#567 — August 27, 2025 Read the Web Version Go Weekly Container-Aware GOMAXPROCS — The official Go blog kicks off a promised series of posts on Go 1.25’s new features with a look at some tweaked container-aware behavior around GOM...
Garbage Collection In Go : Part III - GC Pacing
Go’s garbage collector is designed not only to manage memory safely but also to pace itself intelligently, striking a balance between low latency and high throughput. This blogpost explores how the GC adapts its pace to workload demands, demonstrated through both sequential and...
Testing Time (and other asynchronicities)
A discussion of testing asynchronous code and an exploration of the `testing/synctest` package. Based on the GopherCon Europe 2025 talk with the same title.
