New blog post published 🥳 Migrating my NAS from CoreOS/Flatcar Linux to #NixOS In this article, I want to show how to migrate an existing Linux server to NixOS — in my case the CoreOS/Flatcar Linux installation on my Network Attached Storage (NAS) PC. michael.stapelberg.ch/posts/2025-0...

New blog post! 🥳 How I like to install NixOS There are many ways to install NixOS, and in this article I will outline how I like to install NixOS on physical hardware or virtual machines: over the network and fully declaratively. michael.stapelberg.ch/posts/2025-0... #linux #nixos

At this week’s RIPE meeting, Simon Leinen from SWITCH talked about using my github.com/gokrazy/rsync/ memory-safe rsync implementation for diversity, reliability and security! Find the video recording at ripe90.ripe.net/archives/vid... #golang

TIL: Apple’s migration tool supports Thunderbolt networking, so by connecting two Macs with a Thunderbolt cable, you can transfer data much much faster than with Gigabit Ethernet: the migration tool measures the connection with 3 GB/s peak speed (actual migration speed: >> 500 MB/s):

Went to see Tangerine Dream live tonight! Great tracks, visuals were stunning and overall a good time :) If you haven’t heard of them: they *defined* electronic music in Germany back in the 1970s and have been active ever since. They made the sound track to GTA V! en.wikipedia.org/wiki/Tangeri...

@thepudds.bsky.social is my hero So far, up to 15x faster escape analysis for the Go compiler when compiling the TS checker package. End to end that's an 8x faster compiler of the checker package for us, bringing it down from 50 seconds to 6 seconds. github.com/golang/go/is...

Did you know? My github.com/gokrazy/rsync module can be used as a library — both its client and its server accept the io.ReadWriter interface type :) To show that this works and to show the flexibility this enables, I put together an rsync-over-gRPC demo: github.com/stapelberg/r... #golang

My website/blog michael.stapelberg.ch is now self-hosted from Zürich! 🇨🇭 I’m now using the Caddy web server on a machine running my router7.org (which in turn is built on my gokrazy.org) to serve the static files (previously: GitHub pages + CloudFlare) More services to follow! #golang #selfhosting

New blog post! 🎉 Tips to debug hanging Go programs michael.stapelberg.ch/posts/2025-0... #golang

Last November, I blogged about using ephemeral PostgreSQL DBs for Go testing. It was worth digging deep into the topic, because the insights transfers well. For example, I recently optimized the gokrazy/rsync tests like so: (1/n) #golang

Shoutout to @zekjur.bsky.social for showing me the way. Magit really is great.

I just watched this video of Byran building a laptop from scratch and it’s truly an internet moment of the best kind 🤯 www.youtube.com/watch?v=fks3...

PSA: With macOS 15 Sequoia (released in September 2024), Apple has started shipping openrsync (created by Kristaps Dzonsons, from OpenBSD) as an alternative to the original rsync (“tridge”, from the Samba project). 🧵

Any last tips or recommendations before I click order on this PC build? This will be the replacement for michael.stapelberg.ch/posts/2022-0..., i.e. mostly doing compilation, browsing and similar. Goals are: silent, low idle power, fast. (I’ll keep using my current nVidia GPU for now.) #linux #pc

I often see developers make mistakes in their tutorials that trip up readers, so I thought a lot about what makes some tutorials effective and what makes others frustrating.

With commit github.com/gokrazy/brea..., you can use #emacs TRAMP with gokrazy.org devices 🎉 Maybe this makes other remote access solutions work, too, but I haven’t tried. Reports welcome!

Did an analysis of the various go-mail packages in the #golang ecosystem. Instead of finding “the best fork”, it seems like I’ll need to switch to wneessen’s alternative (not a fork). Did I miss any significant development here?

New blog post! 🎉 Testing with Go and PostgreSQL: ephemeral DBs Let’s say you created a #golang program that needs a DB — you installed PostgreSQL, wrote the Go code, and everything works; great! But how do you best provide PostgreSQL to your automated tests? michael.stapelberg.ch/posts/2024-1...

Here’s a great demo about a (game) dev env: www.youtube.com/watch?v=72y2... It starts with updating assets with live reload and it only gets better from here. I strongly recommend you watch this, and then compare your dev env! Maybe it will give you some inspiration/motivation!
