Finding Goroutine Bugs with TLA+
My job these days is teaching TLA+ and formal methods: specifying designs to find bugs in them. But just knowing the syntax isn’t enough to write specs, and it helps to have examples to draw from. I recently read Chris Siebenmann’s Even in Go, concurrency is still not easy and thought it would make a good case study for writing a spec. In it, he gives an example of Go code which deadlocks:

Alright, time to write some code and implement some Z80 registers.

gosentry: fuzz golang with LibAFL.

Go fuzzing was missing half the toolkit. We forked the toolchain to fix it.
We built gosentry, a fuzzing-oriented fork of the Go toolchain that keeps the standard fuzzing workflow while using a stronger stack underneath.

Hrmm, I feel like this might eventually lead to pain...however, will probably be very useful once I get farther down the road writing this Z80 emulator.

Finally found a real use for go.work and it's amazing - code is split across several git repositories and all modules depends on each other. This is so much better than go.mod replace.

Shard your locks: benchmarking 6 Go cache designs
I built the same in-memory cache six ways with the Go standard library and benchmarked them across read/write mixes and core counts. Lock striping wins by up to 8×, sync.RWMutex turns out to be a trap, and one design gets slower the more cores you add.
