Sometimes you need a better GPU for testing - service offerings like runpod.io or salad cloud is cool, for setup a quick docker container for testing, however currently both runpod and salad are missing the ability to setup some kind of sidecar, which would allow user to setup for example a vpn connection to internal network, so you can access the external container from your secure network and not just directly throught the internet.

Recently, during migration from one host to another, we had a idea to run the docker in swarm mode, so i future, when we needed more capacity, we could just add more nodes “without the complexity of kubernetes”. However, after starting the working docker-compose in the docker swarm mode, i noticed that the traefik was not picking up the labels from the containers and i couldn’t really figure out why.

I’m still using my chromebook with coreboot as a portable thinclient. Due to small built-in storage (only 16GB), i’m also using microSD card as a secondary storage for larger files and project. However i was strugeling with microSD card not being mounted at boot (waiting for device), my solution was to just physically eject and insert the card at boot, but it is pretty inconvient and is probably destroying the card pins.

Recently, I was trying to upgrade my toy K3s cluster using System Upgrade Plans operator. Applied example manifest, control-plane upgraded without issues, but pod for upgrading worker node was constantly restarting with error in logs exec /bin/upgrade.sh: exec format error. I would kinda expect that issue on ARM system (although we come a long way in the last couple of years!), but my nodes are running on x86 CPU, so what is happening?

At the beginning of this article, i would like to mention that i’m a noob when it comes to android custom kernel or ROM development, so some of these information may be obvious to some of you, but it was relatively hard to find one place with up-to-date information on this topic.

Backstory - why i want to compile the kernel for my phone?

My current phone is the Xiaomi Mi 9 - i’m very happy with this phone, it is more than fast enough for my everyday needs, and the photo quality (especially on gcam) is also pretty good. My main issue with this phone was under MIUI 12 - it had a couple of annoying bugs that will probably never get fixed:
