One thing I'd like to see eradicated from math and engineering classes is the definition i=sqrt(-1). It gets you into trouble! . i^2 = sqrt(-1) * sqrt(-1) = sqrt((-1) * (-1)) = sqrt(1) = 1 ??. Better define as i^2 = -1; that's all you need. NO MORE sqrt(-1) PLEASE!

It's a shame that the symbol π is used to represent the ratio between a circle's circumference to its diameter when the capital letter Theta (Θ) literally IS a circle with its diameter. 🥲

When seeing a plot of a function R² → R, do you prefer small values dark and large values light, or the other way around. (See comments for examples.).

For millennia, the circle has been considered the most perfect of shapes, and the circle constant π captured the geometry of the circle in a single number. But π is wrong, and it’s time to set things...

Two years after @github introduced math in Markdown, support for it is still poor. @gitlab, since the merge of has made a big leap forward though! @giteaio is in okay shape, though little has changed recently.

TLDR: Markdown + math is hard. GitHub is bad, Gitea better, GitLab best. Backticked syntax trumps $-syntax.

RT @HenrySchreiner3: Python 3.13 beta 1 is out, which means it's time for my yearly post on what's new:

Python 3.13 betas are out (Edit: 3.13.0 is out!), which means the features are locked in. For the first time in thirty years, Python has a new, more colorful REPL! There’s also a no-GIL …

With @astral_sh's new Python installer `uv` + gh-actions cache, we were able to bring down our dependency install times from ~100 s to <10 s. Now we just need to bring down our actual test times! 😅.

Do you ever get a hunch that matplotlib's architecture is a little "weird"? One of my favorite under-the-radar projects in OSS is @tacaswell's prototype for a more sane matplotlib foundation. Stars on GH: 12.

Does anyone have a recommendation for a #Python Markdown parser and renderer? I need to parse, make some changes here and there, and then render back with only the changes I made. All options I've checked so far are buggy (e.g., .

6/28, happy tau day!. I've added some pictures to my write-up also showing off GitHub's math functionality. My experience with pi vs. tau: If you find a formula involving pi, its generalization shows that it really is tau/2. (See screenshot.). @TauDay

The number of questions asked on @StackOverflow has been declining for a number of years (despite a significant uptick when the Corona lockdowns hit us), but especially popular languages/frameworks took a nosedive recently. #ChatGPT?. All plots at.

Earlier this year there were rumors about #Android14 getting support for using your device as a #webcam. I'm super-hyped about this. Let's finally ditch those laptop cameras! They've never been any good and we all have something WAY better in our pockets.

Would you rather have a 3D spherical pizza with radius 1, a 9D spherical pizza with radius 1, or a 27D spherical pizza with radius 1? @martinmbauer.
