Thoughts, ideas and lessons learned while creating a new massively scalable authoritative DNS server in C++
Hi!
Hi, my name is Jarle. I am a Freelance C++ developer. I have spent quality time with code for 35+ years, and I still love it!
This is my professional blog, where I write about stuff I research or discover during my daily work on various projects.

The great mystery on how to make durable, asynchronous functions for asio.

Taming port-forwarding to k8s pods with SOCKS
Some times, especially during development, I need to connect to lot's of k8s pods using command-line curl (or other tools I have on my PC). The traditional solutions is to install a "jump-pod", and execute the commands there. Today I had enough and installed a socks proxy pod in the k8s cluster.
Deploying a docker-registry in your private kubernetes cluster
It is surprisingly hard to deploy a private docker registry anywhere, and kubernetes is no exception.
Deploying distcc in a kubernetes cluster to transform it into a big, fast build-machine.
For C++ developers, more cores to build on means faster builds. If your project is big, more cores can make a significant boost. If you have a local k8 cluster with spare CPU, it's amazingly simple to turn it into a build-machine.
