Cheuk Ting Ho<p>As a final preparation for the <a href="https://fosstodon.org/tags/PyO3" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>PyO3</span></a> workshop tomorrow at <a href="https://fosstodon.org/tags/EuroPython" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>EuroPython</span></a>, I have updated some exercises to ensure thread-safety. We are ready for <a href="https://fosstodon.org/tags/FreeThreaded" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>FreeThreaded</span></a> <a href="https://fosstodon.org/tags/Python" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Python</span></a>! Make sure you have the setup ready: <a href="https://github.com/Cheukting/py03_101" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://</span><span class="">github.com/Cheukting/py03_101</span><span class="invisible"></span></a></p>
Cheuk Ting Ho<p>Are you interested in how <a href="https://fosstodon.org/tags/Rust" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Rust</span></a> changes the ecosystem in <a href="https://fosstodon.org/tags/Python" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Python</span></a>? Are you creating Python libraries using Rust code via <a href="https://fosstodon.org/tags/PyO3" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>PyO3</span></a>? Show your interest in participating in Rust <a href="https://fosstodon.org/tags/Summit" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Summit</span></a> in <a href="https://fosstodon.org/tags/EuroPython" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>EuroPython</span></a> 2025 now!

Wolf<p>I did, during my previously mentioned workshop, do one thing to offend <a href="https://hachyderm.io/tags/Rust" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Rust</span></a>’s <a href="https://hachyderm.io/tags/borrowchecker" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>borrowchecker</span></a>. I was implementing an Account struct that had a current balance and a Vec containing a history of balances. This was using <a href="https://hachyderm.io/tags/PyO3" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>PyO3</span></a> so there are some special types. Because of inheritance, I have self_ instead of self. Here’s the bad thing I said:</p><p>self_.history.push(self_.as_super().balance);</p><p><span class="h-card" translate="no"><a href="https://hachyderm.io/@algo_luca" class="u-url mention" rel="nofollow noopener" target="_blank">@<span>algo_luca</span></a></span> had to explain it to me. He didn’t even need to think about it. He instantly knew what was wrong. Now I am enlightened. I won’t make this particular kind of mistake again. </p><p>Of course the mistake is that I was trying to use a mutable reference (so I could push to history) and anything else at the same time.</p>
Nigel Small<p>After lunch, it looks like I'll be heading to "Writing Python modules in Rust - PyO3 101" because it would be rude not to.</p><p><a href="https://fosstodon.org/tags/pycon" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>pycon</span></a> <a href="https://fosstodon.org/tags/pyconie" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>pyconie</span></a> <a href="https://fosstodon.org/tags/python" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>python</span></a> <a href="https://fosstodon.org/tags/rust" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>rust</span></a> <a href="https://fosstodon.org/tags/pyo3" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>pyo3</span></a></p>
mgorny-nyan (on) :autism:🙀🚂🐧<p>Wiecie, że przepisywanie fragmentów paczek Pythona w Ruście idzie super, nie?</p><p>Dlatego już prawie rok użytkownicy <a href="https://pol.social/tags/CEPH" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>CEPH</span></a> mają problem, bo rustowe Cryptography kłóci się z nowszymi wersjami rustowego BCrypt.
