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.
A new record prime number has been found! The 52nd Mersenne prime was found this week: 2136,279,841-1 is a prime, more 41 million digits long. I played a very small part in finding the 39th Mersenne back in the early 2000s, so this is exciting news. Also an interview with Luke Durant, the man who found it.
For more than 70 years computer scientists have studied sorting algorithms. Amazingly, we're still finding ways to make them faster and more memory efficient. Python recently replaced its legendary TimSort, and today Rust 1.81 released with two new adaptive sorting algorithms featuring serious performance improvements.
The well known saying about eating and having cake makes a lot more sense if you reverse the subjects, ie. "You can't eat your cake and have it too". Did you know that until recently you could be sued for singing the Happy Birthday song?
The command-line tool of the day is hyperfine. It's a very nice replacement for good-ole time for measuring (and even comparing) program execution time.
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!
