Now that I have started my Python project devto-followers2md, I have recently started checking my code with Ruff, a fast Rust-based Python linter and code formatter. I also started using pyright, (yes, I know it is very ironic, it is made by Microsoft), and will be working on making sure the project aligns with its standards too.

Zulip
Zulip server and web application. Open-source team chat that helps teams stay productive and focused.
Zulip is building the world’s best collaboration platform, and we’re committed to keeping it 100% open source. Zulip is the only modern team chat app designed for both live and asynchronous conversations. Our product serves as the communication hub for businesses, open-source projects, educators and communities around the world.
We’re looking for a senior backend/infrastructure engineer to join our small core team and build, operate, and scale Zulip — both as we run it on Zulip Cloud, and as thousands of self-hosters run it themselves. The Senior Backend/Infrastructure Engineer will work across backend features, performance, and infrastructure; review code from both staff and open-source contributors; and share responsibility for keeping Zulip Cloud production healthy. You will also have the opportunity to provide technical direction and mentorship to the team.
Check out https://zulip.com/jobs/ to learn more about this and other opportunities at Zulip, and apply at jobs@zulip.com.

Interesting proposal, but with severe risks: becoming dependent on a single specific compiler and rustc could include malicious code that isn’t obvious to an outside auditor. See https://aeb.win.tue.nl/linux/hh/thompson/trust.html Ken Thompson demonstrated this.
But what will the future of RustPython be? https://github.com/RustPython/RustPython/
Major shifts like this are complex, not so only from a technical perspective but even more because a lot of humans with different opinions are involved. But radical changes are sometimes needed to be innovative again.

undetected-chromedriver
Custom Selenium Chromedriver | Zero-Config | Passes ALL bot mitigation systems (like Distil / Imperva/ Datadadome / CloudFlare IUAM)
More importantly, blocking doesn't actually work. There is no identity system baked into HTTP, so circumventing these blocks is very easy. It's so mundane that it’s offered as a professional service, and popular modules exist to make your bot look like a default browser. There simply is no reliable way to block automated scraping while allowing normal use without massively impacting the openness of the web.
