-
struct Q demands its payload outlive the program. Assigning a field after construction (q.0 = Some(&l), where l is stack-local) unifies the types covariantly β and that unification does not re-check the 'static bound. A Drop impl that pushes the value into a static list assumes the bound held; it leaks the reference out; a downcast_ref::<&'static String>() reads freed stack memory. With AddressSanitizer, per the issue, the same program crashes with stack-use-after-scope.

ripgrep
ripgrep recursively searches directories for a regex pattern while respecting your gitignore
Project mention: ripgrep Missed the CSV Files. I Almost Designed a Collector We Already Had. | dev.to | 2026-10-14The research built its file inventory with a plain rg --files. ripgrep's defaults are designed for searching code, and the ripgrep user guide is explicit about what they filter out: paths matched by .gitignore and ripgrep's own ignore files, plus hidden files and directories. Those are the relevant filters for this file listing; binary detection concerns searching file contents, not rg --files inventory. The Search Console exports were CSV files in a gitignored location. A default listing was never going to include them.

Project mention: Disney+: New user agreement allows ads before movies in all subscriptions | news.ycombinator.com | 2026-09-21
Bitwarden, while not quite as polished, works well. If you have your own server at home you can even self-host, which I do. It's an open source server side app called Vaultwarden [https://github.com/dani-garcia/vaultwarden] which connects to the Bitwarden app.
I think the iCloud password manager also works pretty well, provided you're using Apple products.

This was Fig's smartest move. Every other approach at the time either forced you onto a brand-new terminal emulator (Warp, Tabby) or left you stuck with the weak completion of the day. Fig chose to piggyback instead β it supported macOS Terminal, iTerm2, Tabby, Hyper, Kitty, WezTerm, Alacritty, and even the embedded terminals in VS Code, the JetBrains IDEs, and Android Studio. You changed nothing. You installed an app.

Warp engineer here - Warp is open source as well if there's anything we can do to improve the default experience. Otherwise, it's available to fork and customize: https://github.com/warpdotdev/warp

But for reading code, scripts, configs, Markdown, YAML, JSON, or anything where your eyes are expected to survive the experience, bat is much nicer.

starship is the prompt. That's it, that's the whole job, but it does that job well: git branch and status, language versions, command duration, all rendered fast and only when relevant, so it doesn't clutter the prompt with things that don't apply to the directory you're in. The reason it matters more than "cosmetic" makes it sound is that a good prompt answers questions before you have to ask them. Am I in a dirty git tree? Which Node version is active here? Starship tells me before I type anything.
