Today I learned that if you run
```
docker compose restart
```
after you changed your docker-compose.yml file, it won't use your new configuration, instead you need to
```
docker compose down
docker compose up -d
```
caused me a bit of a headache this morning.

I have been running a project recently on Hetzner, just Linux servers, no Kubernetes, no AWS manged servers. Created the servers via Terraform and then used Ansible for configuration management, basically rediscovering how people where doing stuff before k8s.

So I was gonna start working on a Kubernetes operator and did the scaffolding with kubebuilder. After 4 commands, 1 Kubebuilder init and 3 kubebuilder create api, I now have 70 files containing 4200 lines of code - damn that's a lot of boilerplate.

kubernetes memory requests and limits are actually quite confusing with a lot of contradictory advice floating around - also the whole cgroups v1 vs v2 thing - I've gotta set up my own experiments to get to the bottom of this I guess

I have been a bit silent on Bluesky, it didn't feel like I was finding the kind of conversations that I was looking for but now I started taking some time to setup proper feeds instead of just looking at "Following" and it does wonders - I guess as a result I will also start posting more often again

Just done watching @t3.gg bashing on Firefox and personally, most of his points don't matter all that much too me but what keeps me on Firefox are
* proper ad-block with ublock
* multi-account containers (managing multipe AWS accounts on chrome is actually unbearable)

Excellent news! If you do nothing different, your AWS bill will be 10% lower for February than January.
No need to thank me, it’s what I do.

It's the holidays, but I still carve out a little time of Kafka transactions. Diary entry 5 - adding AddPartitionsToTxn request/response, TC elections and producer fencing (TLA+).

Verifying Kafka transactions - Diary entry 5 - AddPartitionsToTxn in TLA+ — Jack Vanlightly
I have written the second iteration of the TLA+ specification which now
includes:
* The AddPartitionsToTxn request/response.
* Transaction coordinator (TC) elections so that leadership of a
transaction log partition can now move between brokers.
* Producer fencing and some of the abort transaction logic.

Main goal for 2025 is to launch the best language learning app on the planet @kosakata.bsky.social
Web version is slowly taking shape, the backend is mostly ready, still need to work on mobile
Going to have the first early alpha users soon and squash out bugs

So far ghostty is living up to expectations for me, no configuration needed, just set a theme (catppuccin, which it shipped with, no need to install) nothing else - and everything just works so far

Does YouTube allow to blacklist words? "Reacting to" and "reacts to" would be great to get rid of for good - I hit not interested everytime but once in a while they pop up again - also maybe "react" while we are it :P
