Dr Sam MorrellMy first experience with <a href="https://mastodon.social/tags/chatgpt5" class="mention hashtag" rel="nofollow noopener" target="_blank">#chatgpt5</a>. I queried how to write some <a href="https://mastodon.social/tags/python" class="mention hashtag" rel="nofollow noopener" target="_blank">#python</a> code to write out unformatted, binary files so my <a href="https://mastodon.social/tags/fortran" class="mention hashtag" rel="nofollow noopener" target="_blank">#fortran</a> code could read it. Proceeds to give me a load of <a href="https://mastodon.social/tags/NumPy" class="mention hashtag" rel="nofollow noopener" target="_blank">#NumPy</a> code. Completely neglects to mention the <a href="https://mastodon.social/tags/SciPy" class="mention hashtag" rel="nofollow noopener" target="_blank">#SciPy</a> FortranFile class that can trivially read and write, and appears on the first page of a search. This is going to be a bumpy ride!

John-Mark GurneyIf you're writing python libraries, DON'T REQUIRE fileno ON FILE OBJECTS!Dealing w/ the bullshit that numpy.fromfile wants the fileno attribute on a file object. Yes, it's slightly faster, but it also makes it harder to mock when doing testing.Now I'm going to have to deal w/ creating a temporary directory, writing the file, and cleaning up afterward. Things that unittest.TestCase should have an option to do, but doesn't. Luckily I've dealt w/ this BS before, so I'll just copy the code from another project.<a href="https://flyovercountry.social/tags/numpy" class="mention hashtag" rel="nofollow noopener" target="_blank">#numpy</a> <a href="https://flyovercountry.social/tags/Python" class="mention hashtag" rel="nofollow noopener" target="_blank">#Python</a> <a href="https://flyovercountry.social/tags/Testing" class="mention hashtag" rel="nofollow noopener" target="_blank">#Testing</a>

John-Mark GurneySince I couldn't figure out how to use numpy.take, and LLMs couldn't figure out how to do what I needed to do, I read the numpy slicing chapter, and I came up with the following: indexes = np.arange(W * H) rgb[0, i].flat = c[0].flat[np.array(reps[i].flat) * (W * H) + indexes]EDIT: it was broken, needed to add in the position index and simplification.<a href="https://flyovercountry.social/tags/numpy" class="mention hashtag" rel="nofollow noopener" target="_blank">#numpy</a> <a href="https://flyovercountry.social/tags/Python" class="mention hashtag" rel="nofollow noopener" target="_blank">#Python</a>
