Za sprawą zlecenia z #ExMakhina, Inc. (@cJ), sporo paczek Pythona w #Gentoo dorobiła się wsparcia #PyPy, m.in.: #IPython, #Jupyter Notebook, #MatPlotLib, #ScIPy, #SymPy.

Chciałbym także podziękować autorom PyPy za ich wsparcie, zarówno w kwestii poprawiania błędów w PyPy, jak również udzielaniu pomocy innym projektom, by poprawić ich zgodność z PyPy. Praca z wami jest przyjemnością!

Na koniec, poznałem ważny argument za pracą nad wsparciem PyPy w projektach: nawet jeśli dana paczka nie działa szybciej na PyPy, to może być zależnością w większym projekcie, w którym PyPy ogółem przynosi lepszą wydajność.

I found some interesting trends today while working with the simplify function from #Sympy as part of an experimental project for @formak. A large portion of the time is spent in list comprehensions and calling simplify recursively, which seems to “confuse” the flame graph representation.

Also, I think flame graphs are pretty to look at

Rebuilding #SymPy ‘s internals from the ground up, towards a faster and more flexible implementation https://oscarbenjamin.github.io/blog/czi/post1.html

😂 Here I am, entering an equation for the Monin-Obukov length (a turbulence parameter) into #SymPy, and SymPy is like: No! 😂

WTF is happening here? Vars are just symbols with positive=True and real=True, except for L_MO and F_H which have positive=False.

Interestingly, if I constrain F_H to positive, the equation stays an equation and is not just False. 🤔

EDIT: Aaah, positive=False means negative 🤦 SymPy did its job! 👍 Describing problems helps! 😃

🤯 Holy sh*t, #sympy is such a crazy powerful :python: #Python package, look how much you can get out of a single one-line expression and some fancy decorators and wrappers.

This is from the development version of PARMESAN¹, a Python package for #meteorology #turbulence #timeseries #analysis I'm working on @umphy and that I plan to submit to @joss in near future.

It seems I'm having ALOT of fun writing financial contract rules into #sympy 😊

Even just being able to render reasonable versions of these financial clauses is already a great help - I don't know why I didn't do this years ago.

Learn how to symbolically #solve #math equations using computer #algebra in #Python: With the release of #SymPy 1.12, the symbolic #equation #solving guide pages I wrote are all live in the latest version of the documentation. I wrote ten pages on topics such as systems of #equations, ordinary #differential equations, #polynomials, #inequalities, #matrix equations, and Diophantine equations, and #numerical solving. https://docs.sympy.org/latest/guides/solving/index.html
