Many languages, one notebook: Python (NumPy, SymPy, plots), R with ggplot2 and tidyverse, SWI-Prolog, Bash, JavaScript, Lua, TypR and ClojureScript.
Pick a language per cell; runtimes load when first used. Cells share files, so R can read what Python wrote. #rstats #python

Das mit den Primzahlen gibt's ja alles schon. 😢 Hab mir durchgelesen, wie die Profis das machen. Das ist methodisch sehr interessant, aber da kann ich nichts dran verbessern.

what's a Sympy villain?
when having the model render stuff i basically just let it see all my work & then also give it a python venv that has torch, npy, scipy, sympy, pillow, matplotlib &c &c & let it do whatever w/ that

Sympy villains don't do much for me. It's about how much they entertain me, which is why I love me some campers. Miguel I assume is the former category and, no, didn't work on me.

Using SymPy to validate homework feels equally weird and rewarding.

Even with SymPy, Python evaluates literals like 0.1 + 0.2 or 1/3 to binary floats before SymPy sees them. For exact equality, pass strings or ints to SymPy Rational('0.1') + Rational('0.2') == Rational(3, 10) (or fractions.Fraction); for floats, use math.isclose.

I graded partial gold patches on 25 SWE-bench Verified sympy tasks. In 4, a half-fix passes every graded test yet behaves unlike gold: one keeps the exp_polar bug in polylog(1,z), one raises on infinite bounds. "Resolved" means the named tests pass, not that the issue is fixed.

I've internalised that test for == with floating point numbers is a bad idea.
Not sure if there's a better way though, short of using like sympy or something for the algebra

As Scott Steiner would put it: "No sympy."
ok so actually if you do the math you get a^3b - 4a^2b + 8a = 0 and the llm that did it in sympy for me went and factored out a factor of "a" without fucking telling me about it and that means that the *actual* curve is also zeroed out along the line a=0 in addition to the quoted curve
a²b - 4ab + 8 = 0
what is this curve. do you know a function that happens to look like this, probably related in some way to quadratics
