I build and benchmarked 17 versions of Python against each other so that you don't have to. Let's compare the performance of every Python version from 2.6 all the way to almost-released 3.13. Spoiler, it's great!
Running Klipper on your 3D printer requires a Linux server connected to your controller board. The Raspberry Pi Zero 2 is a great choice. It's tiny and uses hardly any power, which makes it easy to add to your build. If you don't mind the WiFi networking and have $15, pick one up and follow along to get it set up!
I've been programming in Python for more than a decade, but it's only now that I have had to bring out the big guns: writing a metaclass.
The Raspberry Pi Zero 2 is here! It took six years, but my favourite little computer has finally been upgraded. It's not as jaw-droppingly cheap as it used to be, but $15 for a quad core Linux server still catches my imagination. Mine is still in transit, more to come when it arrives.
Python 3.10 has been released. It's not a huge release, but solid, building on the new parser introduced last year in 3.9. From that has come my favourite change: the improved syntax error messages, brilliant for those of us teaching kids during a COVID lock-down. The banner feature is structural pattern matching - it's like a switch statement, but more. Much more. Performance has also had a nice bump! About 20% better than 3.9 for a simulation I like to test with.
Auckland is under COVID-19 lock-down, so my home office is infested with children. My nine-year-old just demanded that we edit a video and add a voice-over. We found OpenShot, a simple Open Source editor. She finished her project alone after only a little setup help, leaving me to get back to actual paid work. Well worth a crack.

An Australian gentleman re-creating an astronomical computer from 200 BC is unexpectedly fascinating.
