My impression (via social media) has been that these were shadow layoffs.
Last month I asked an investor why they are doing RTO. He said: "Retention, mostly. And morale."

@metalmatze.de hi, weโve met at kubecon and we talked about a project for benchmark trend visualization. If you found it again, I would love to see it. Thank you so much for the recommendation.

With more #golang conferences and meetups joining BlueSky, here is a starter pack with the ones I've seen so far!
Did I miss any? Please ignore the fact that I can't remove myself from my own list!

Just finished "The Go Programming Language" by Donovan and Kernighan. Extremely well structured and well written book, as might be expected from these authors. #golang

Why read a book about a programing language instead of just learning it online? (1 of 4)
The #golang encoding/json/v2 proposal is live!
Huge props to Joe Tsai for the hundreds of hours he poured into this project.

weak.Pointer (Go 1.24+), runtime.AddCleanup (Go 1.24+), and sync.Map combine wonderfully into a 20-lines weak map. #golang
It associates values to keys, with automatic garbage collection once the key becomes unreachable. Using it to tie precomputed FIPS keys to PrivateKey values we can't modify.

Your periodic reminder about the Bluesky network analyzer, a surprisingly useful tool for finding people you know who you probably intended to be following if you knew they were here. It's eerily good, especially if you use "favour niche accounts" mode.

Did you know you that you can run Go 1.24rc1 (or any other version) by just setting an environment variable?
$ GOTOOLCHAIN=go1.24rc1 go version
go: downloading go1.24rc1 (darwin/arm64)
go version go1.24rc1 darwin/arm64
This is supported since Go 1.21 (August 2023).

I wrote up how my NAS is now just a big initramfs based on Alpine Linux. words.filippo.io/frood/
It's been pretty great. Immutable, declarative, and very very simple. Just some files, a list of packages, and a short script.
The doc is in `go help mod edit`. How did I get there...? it's a long story.
