If you have a heavily utilized Python application, you should look into updating it to Python 3.11. Check out this graph that shows the CPU usage of the servers running PyPy (which is itself written in Python).
You can clearly see when they upgraded from 3.10 to 3.11!

Alright, building the container image looks pretty straightforward. But I couldn't find any docs on how to apply that overlay to the node. Do I need to set an osImageUrl in the MachineConfig?

Fair point, but I have no idea (yet!) about CoreOS layering - something to look into in the future. :-)
Also, in the end it's just one MachineConfig that needs to be applied, so I'm not sure how much easier it can get with layering. 🤔

Experimenting with eStargz image pulling on OpenShift
eStargz is a new, OCI-compatible image format for containers. It has the advantage that the only the files necessary for starting a container need to be downloaded (at least initially), instead of downloading everything upfront (even though it might not be needed).
In this post I’m showing how the Stargz Store plugin for CRI-O can be installed on OpenShift (OKD): https://blog.cubieserver.de/2022/experimenting-with-estargz-image-pulling-on-openshift/
I wanted to set up an external hard drive as a secondary backup mechanism for various computers. exFAT seems like the most widely supported filesystem across OSes. But then I had to find out that exFAT supports neither hardlinks nor symlinks :-(
This post by Jessie Frazelle from 2015 (!) has aged extremely well (apart from the fact that it's using OpenVPN, whereas today we'd like to use Wireguard/Tailscale/ZeroTier/...):
How to run a VPN in a container and attach other containers to that VPN subnet.
