I’m thinking about “upgrading” my server from Ubuntu to Fedora and thereby also making Uncloud a part of my routine, but…… This can be done, but doing a container style setup, does mean I need some extra infra, like a container registry, also my DNS server

Unpush is an experimental attempt to write automatic CI/CD in Uncloud, it either works via web hooks or polls a repository for changes.

This is the final report from DENIC on the outage they experienced on the 5th of May 2026.

Uncloud’s docs are great, but a few things are buried a bit.

Had some fun playing with my fork of Uncloud.

Caddy in a distributed setup (i.e. running on more than one machine) is a nightmare together with Let’s Encrypt ACME challenges… What happens is that Caddy A starts a challenge, which ends up at Caddy B and this can ping-pong for days before any certifica…

Currently uc doesn’t have a prune subcommand to prune images, and even if it had it would still be a manual operation.

Prometheus metrics are being worked on by me, and will hopefully soon be merged in Uncloud.

Natively Uncloud doesn’t do L4 forwarding.

While pushing this PR, the answer was that this was already working!

This is a good article on how to use testscript in Go(lang).

I’m playing with Uncloud to see if it is something we can use at $WORK.

For the longest time I wanted to see the performance impact of my changes.

Recently I’ve started to move all my project to Codeberg.

Ever felt the need to do something with PAM, like implementing 2FA in SSH?

Because I was fed up with the lack of options (none), I write a tool that can format Go HTML templates: you can find it here.

After dealing with Go templates (also HTML templates) for more than a year and keep loosing track of where each block {{end}}s I finally did something about it.

I’m using Kong the CLI argument parser to create manual pages from the arguments and help described in the Kong structure that tells your CLI how to parse its command line.

I’m a fan of Kong the CLI argument parser, I use it to automatically create manual pages, (bash) completion and do a lot of validation inside it.

Played more with TinyGo, but it always generates code for (minimal) reflection - i.e. the reflect package, because it requires that for its map implementation.

Again some progress.

Following up from the previous blog post… I’ve got a JSON file with the string ‘bpf’ in the correct place.

So I had this itch that I wanted to make a Go program compile to eBPF and be able to load that program in the Linux kernel by use of bpftool.

What if I could program eBPF in pure Go?

In the olden days with X11, you could just do x11-forwarding in SSH and remote cut and paste would work.
