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.

pyscript
An open source platform for Python in the browser. https://pyscript.net Docs: https://docs.pyscript.net/ Try it: https://pyscript.com/ Community: https://discord.gg/HxvBtukrg2
Can someone please ELI5 what this means for Deno and Python? TFA: "deno is being distributed on pypi for use in python projects" makes it sound like you can now `import deno` and have a JS engine/subsystem in Python, like we finally came full circle from [PyScript](https://pyscript.net/).
However, other comments make it sound like a bunch of other projects have discovered that PyPI is a good distribution channel. Which, to me, sounds like using the Internet Archive as your CDN. Is PyPI the next apt/yum/brew or what?

Monorepo gave you atomic cross-service changes, a single dependency graph, unified CI/CD, and zero version skew between internal libraries. The cost was large clone sizes, slower CI without build caching, complex permission models, and the need for specialized tooling like Bazel, Pants, Nx, or Buck2 to keep builds fast.
