ZeroBrew applies UV's model to Mac packages.

ZeroBrew takes some of the best ideas from UV and applies them to Homebrew.

Quote, packages live in a content-addressable store, so reinstalls are instant.

Downloads, extraction, and linking run in parallel with aggressive HTTP caching.

It pulls from Homebrew's CDN, so you can swap brew for ZB with your existing commands.

This leads to dramatic speedups, up to 5x cold and 20x warm.

This is all quite experimental at the moment, but it appears to be picking up steam.

I also appreciate the author's approach to LLMs.

Quote, I spent a lot of time thinking through this architecture, testing, and debugging.

I also use Claude Opus 4.5 to write much of the code here.

I'm a big believer in language models for coding, especially when they are given a precise spec and work with human input.

LLMs in your career.

Here's Phil Eaton, quote, "...the jobs that were dependent on fundamentals of software aren't going to stop being dependent on fundamentals of software.

And if more non-developers are using LLMs, it's going to mean all the more stress on tools and applications and systems that rely on fundamentals of software."

All of this is to say that if you like doing software development, I don't think interesting software development jobs are going to go away.

So keep learning and keep building compilers and databases and operating systems and keep looking for companies that have compiler and database and operating system products or companies with other sorts of interesting problems where fundamentals matter due to their scale.
