David BremnerIt's been a long time since I tried <a href="https://mathstodon.xyz/tags/SymPy" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#SymPy</a>, but yesterday I went back to it to do some simple symbolic linear algebra, and I have to say it is pretty good these days.The same project was also the first time I used <a href="https://mathstodon.xyz/tags/orgmode" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#orgmode</a> source blocks to insert generated output (from SymPy i this case) into a document. It took me a few times returning to the docs, but it is pretty nice for sharing calculations with fellow researchers.

nenI like to do math, small prototypes and other experimenting with Python in Jupyter notebooks. NumPy, SciPy, SymPy and Matplotlib have been very handy.But recently Python was too slow for what I was doing and I had trouble juggling Numpy arrays as usual (which is required for speed). I know some <a href="https://mementomori.social/tags/Rust" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Rust</a> so I decided to give <a href="https://mementomori.social/tags/evcxr" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#evcxr</a> a go because it has a Jupyter kernel. And omg, I wasn't disappointed! It was mindbogglingly fast compared to what I'm used to and it also made the hard part of my code way easier to get right.However, I only needed math functions provided by std this time. Now I'm trying to figure out if there are science Rust libs that are convenient enough to replace most Python in my notebooks. I know it's a fragmented space, but maybe one could already gather a comprehensive collection of crates manually.Any recommendations?<a href="https://mementomori.social/tags/RustLang" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#RustLang</a> <a href="https://mementomori.social/tags/SciPy" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#SciPy</a> <a href="https://mementomori.social/tags/NumPy" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#NumPy</a> <a href="https://mementomori.social/tags/SymPy" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#SymPy</a> <a href="https://mementomori.social/tags/SciComp" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#SciComp</a> <a href="https://mementomori.social/tags/Math" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Math</a>

Albert CardonaA math problem:Variables: a, b, c, d, e. Values: 2, 5, 13, 14, 15. Constraints: 1. a is a multiple of b. 2. d is a factor of a. 3. e - b = c. Which variable holds which value? I can't find the solution.Today's math problem courtesy of a 12 year old upset with his "unsolvable" homework. I'm stumbled too.Can <a href="https://mathstodon.xyz/tags/sympy" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#sympy</a> be wrangled to solve this sort of problems? Can't see where to limit the values each variable can take.

(<a href="https://mastodon.zougloub.eu/@cJ" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@cJ</a>), a bunch of <a href="https://social.treehouse.systems/tags/Python" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Python</a> packages in <a href="https://social.treehouse.systems/tags/Gentoo" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Gentoo</a> has gained <a href="https://social.treehouse.systems/tags/PyPy" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#PyPy</a> support, notably: <a href="https://social.treehouse.systems/tags/IPython" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#IPython</a>, <a href="https://social.treehouse.systems/tags/Jupyter" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Jupyter</a> Notebook, <a href="https://social.treehouse.systems/tags/MatPlotLib" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#MatPlotLib</a>, <a href="https://social.treehouse.systems/tags/ScIPy" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#ScIPy</a>, <a href="https://social.treehouse.systems/tags/SymPy" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#SymPy</a>.I'd like also to thank the PyPy upstream for their support, both in fixing bugs in PyPy and in helping other projects improve their compatibility with PyPy. It's really a pleasure working with you!Last but not least, an important point has been made for projects to work on PyPy support: even if your package doesn't work faster on PyPy, it could be used as a dependency of a bigger project where PyPy brings overall performance gain.
