b4 0.16.0 released

Konstantin Ryabitsev has announced the release of version 0.16.0 of the b4 software-development tool. The biggest change is the addition of bug-tracking support: The new "b4 bugs" command integrates with git-bug to let you track bug reports alongside your git repository. Bugs are stored as git objects inside the repo, so they travel with the code and can be shared via git push/pull without any external service. There are also a lot of improvements to b4 review (which was covered here in March), better conflict resolution in b4 shazam, improved history rewriting, and more.

Nelson: rust-lang/rust is adopting an LLM policy

Jynn Nelson describes the Rust language team's new LLM policy on the Inside Rust blog. No one except the author is required to read LLM output unless they choose to: LLM output isn't allowed in public docs, PR descriptions, or Github comments unless it's clearly marked; reviewers aren't required to look at LLM PRs if they don't want to. No one is required to use LLMs to contribute to rust-lang/rust: policies must be written first for humans, and only summarized for machines; LLM reviews cannot substitute for human review or self-review. You are allowed to generate LLM content that only you see, without disclosure, as long as you do not post it anywhere that you expect us to read or review.

There are many gaming emulators for Linux. But a specific Linux Operating System for a handheld system is something that makes for a great way to play older games in a handheld form.
