Two Claude Code sessions in the same folder will sooner or later edit the same file and undo each other's work. A worktree fixes that by giving each session its own copy of the files on its own branch. Here is where Claude Code stores worktrees, how they work, what they share with your main folder, and the small routine that makes them worth using.
I opened Claude Code on a side project after a day away, and it greeted me with a careful reconstruction of what we had been doing, pieced together from the notes file and the working tree. It was right, but it was a guess. The whole conversation that produced that work was sitting on disk, one command away. Here is how sessions actually persist, what a resumed one gives you back, and what it never will.
Software teams generate an ocean of numbers — commits, tickets, story points, lines of code — yet the thing we actually care about, performance, stubbornly resists measurement. This post is about that gap: why individual output is so easy to misjudge, what signals are worth watching, and how to measure teams without corrupting the very behavior you want.
Every web developer knows the anxiety: a new framework trends on social media, a hot take declares your stack obsolete, and you wonder if you've fallen behind. The truth is that the web platform moves on a much slower, much more predictable clock than the discourse suggests — and the roadmap is public. You just have to know where it's published.
This post maps the sources that actually predict where the platform is going: standards bodies, browser vendor programs, runtime release schedules, ecosystem RFCs (request-for-comments proposals), surveys, and events. At the end there's a practical system for consuming all of it without burning out.
I've started using chezmoi to manage my dotfiles: shell config, Git config, editor settings, aliases, and all those small files that make a machine feel like mine.
The basic idea is simple:
chezmoi source repo ↔ my real $HOME files
But the direction matters.
Your .zshrc started as ten tidy lines and has quietly become a 400-line dumping ground of half-remembered aliases, dead exports, and copy-pasted snippets you're afraid to delete. Here's how to clean it up and keep it that way.
Caring isn't just a nicety, it's a productivity multiplier.
