Notes

you should first add your user to the following Unix groups: video, render, docker, ollama
- sudo usermod -a -G render,video $LOGNAME
make sure user ollama is added to groups video and `render
install Docker (ideally in a dedicated VM; see https://gist.github.com/peterwwillis/e2b37e5dd502fd7ffc3833f56feade1e)
this guide installs the latest AMD drivers, but that might be too new of a version of ROCm for ollama (their guide says to use the AMD ROCm v6 tools). the latest AMD ROCm tools actually don't completely install on my Ubuntu 24.04 system due to package conflicts, but some of them install.

Installing and running Docker-in-Docker in a dedicated Colima VM, for AI agent work

You may want to run an AI agent in a "safe" environment, but with ease of use. The closest thing is a VM running Docker. You get the tooling and ecosystem of Docker, with the safety of a VM that you can delete (when the agent goes crazy, breaks out of the VM, steals your wallet and runs off with your wife (I miss you, Elaine...))

Colima is perfect for this, as it creates the VM and sets up Docker. It even keeps persistent files in a different volume than the VM's root disk, so you can just delete and recreate the root disk and your files are still there.

You can have multiple Docker contexts, one for "safe" work (in one VM), and one for "dangerous" AI work (different VM).

The only real downside to Docker is a VM volume filling up with container images.

Setting up ThinkPad T14s Gen4 in Ubuntu Linux

About

I finally settled on a new personal Linux laptop, and it's the Lenovo ThinkPad T14s Gen 4 w/AMD processor, 32GB RAM, and Low-power 500 nits display.

I had mine shipped with Ubuntu, it comes with (I think) Ubuntu 22.04.01 LTS. It's nice because they set up the BIOS to come with Secure Boot enabled for Ubuntu. Everything works out of the box.

Log Files

Nodes

Control Plane log files

/var/log/kube-apiserver.log - API Server, responsible for serving the API
/var/log/kube-scheduler.log - Scheduler, responsible for making scheduling decisions
/var/log/kube-controller-manager.log - a component that runs most Kubernetes built-in controllers, with the notable exception of scheduling (the kube-scheduler handles scheduling).

Worker Node log files

GitHub's highlights of new Git releases

The difference between configuration formats, configuration languages, data formats, and programming languages

There is a lot of confusion out there about what different file formats are and how they are intended to be used. Having used a lot of them over the years, I think I can explain their differences, and when and how to use them.

Data formats

A data format is a file format for encoding data. Typically the format is structured to make it easier for machine interpreting & processing.
