Michael #1: <a href="https://astral.sh/blog/introducing-pyx?featured_on=pythonbytes">pyx - optimized backend for uv</a>

<ul>
<li>via John Hagen (thanks again)</li>
<li>I’ll be interviewing Charlie in 9 days on Talk Python → Sign up (get notified) of the <a href="https://www.youtube.com/watch?v=YKBcgBgK7gc">livestream here</a>.</li>
<li>Not a PyPI replacement, more of a middleware layer to make it better, faster, stronger.</li>
<li>pyx is a paid service, with maybe a free option eventually.</li>
</ul>

Brian #2: <a href="https://www.b-list.org/weblog/2025/aug/06/litestar/?featured_on=pythonbytes">Litestar is worth a look</a>

<ul>
<li>James Bennett</li>
<li>Michael brought up <a href="https://litestar.dev?featured_on=pythonbytes">Litestar</a> in <a href="https://pythonbytes.fm/episodes/show/411/tls-client-hello-guitar-solo">episode 444</a> when talking about rewriting TalkPython in Quart</li>
<li>James brings up
<ul>
<li>scaling - Litestar is easy to split an app into multiple files</li>
<li>Not using pydantic - You can use pydantic with Litestar, but you don’t have to. Maybe attrs is right for you instead.</li>
</ul></li>
<li>Michael brought up
<ul>
<li>Litestar seems like a “more batteries included” option.</li>
<li>Somewhere between FastAPI and Django.</li>
</ul></li>
</ul>

Brian #3: <a href="https://django-remake-migrations.readthedocs.io/en/latest/index.html?featured_on=pythonbytes">Django remake migrations</a>

<ul>
<li>Suggested by <a href="https://bsky.app/profile/browniebroke.com/post/3lw7cfc3p662p?featured_on=pythonbytes">Bruno Alla on BlueSky</a></li>
<li>In response to a <a href="https://pythonbytes.fm/episodes/show/444/begone-python-of-yore">migrations topic last week</a></li>
<li>django-remake-migrations is a tool to help you with migrations and the docs do a great job of describing the problem way better than I did last week</li>
<li>“The built-in <code>squashmigrations</code> command is great, but it only work on a single app at a time, which means that you need to run it for each app in your project. On a project with enough cross-apps dependencies, it can be tricky to run.”</li>
<li>“This command aims at solving this problem, by recreating all the migration files in the whole project, from scratch, and mark them as applied by using the <code>replaces</code> attribute.”</li>
<li>Also of note
<ul>
<li>The package was created with <a href="https://copier.readthedocs.io/en/stable/?featured_on=pythonbytes">Copier</a></li>
<li>Michael brought up Copier in 2021 in <a href="https://pythonbytes.fm/episodes/show/219/htmx-dynamic-and-live-html-without-javascript">episode 219</a></li>
<li>It has a nice <a href="https://copier.readthedocs.io/en/stable/comparisons/?featured_on=pythonbytes">comparison table with CookieCutter and Yoeman</a></li>
<li>One difference from CookieCutter is yml vs json.</li>
<li>I’m actually not a huge fan of handwriting either. But I guess I’d rather hand write yml.</li>
<li>So I’m thinking of trying Copier with my future project template needs.</li>
</ul></li>
</ul>

Michael #4: <a href="https://github.com/djpeacher/django-chronos?featured_on=pythonbytes">django-chronos</a>

<ul>
<li>Django middleware that shows you how fast your pages load, right in your browser.</li>
<li>Displays request timing and query counts for your views and middleware.</li>
<li>Times middleware, view, and total per request (CPU and DB).</li>
</ul>
