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.
My little bulk file renaming script. Inspired by the venerable rename Perl script, my version uses Python regular expressions and focuses on safety. That's not just important, it's super-duper important! Bulk renaming is dangerous enough, but add regular expressions into the mix and It's all too easy to shoot yourself in the foot!
I've been using my own private git server for years and years, but have decided to be a little more public. I've settled on Codeberg.org, a donation-supported service.
Reading the news can erode your faith in humanity. Learning about the work being done on Africa's Great Green Wall reawakens mine. What an incredible project!
My 3D modeling skills are still pretty basic, but I did manage to scratch a personal itch and made an anti-vibration stand for external hard-drives. The size is customisable, and when 3D printed in TPU does a good job of keeping the drive upright — and quiet.
Python 3.13 is already shaping up to be the fastest release yet. While not due for release until October of 2024, its third alpha release came out yesterday. Even this early in development it's already running more than 10% faster than Python 3.12 (and 11% faster than 3.11, and a whopping 54% faster than 3.10).
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.
