Built an app to keep track of food in the fridge :D (and prevent it from rotting)

I am sure many of you have had perfectly good food rot in the fridge and/or have had to clean up afterwards (on top of throwing this away)...

This was a massive problem for me for a long time. So...I decided to build an app that keeps track of groceries. After a few attempts, added a scanner to get the list directly from receipts and recipe suggestions.

I put it on the App Store (it's called SmartFridge, free to use) and figured I'd share it here in case it's useful to anyone else. Link below:

Happy to chat about this and curious to hear your thoughts!

uvr: fast R package and version manager — big 0.4.x update

Quick update on uvr — a fast R package manager written in Rust (uv-style: manifest + lockfile + managed R versions + isolated project libraries). Last time I posted was around 0.2.9; a lot has landed since.

Updates

- R installs got rebuilt from scratch. uvr now installs R from Posit's portable, relocatable r-builds (https://github.com/rstudio/r-builds) instead of custom-patching official installers. This fixed a whole class of macOS breakage, added musl/Alpine support, and made Windows installs work without admin rights. Partial versions work everywhere too: uvr r install 4.5 just grabs the newest 4.5.x, and a 4.5 pin matches it.

- Switching R versions no longer nukes your library on every sync. The old behavior re-wiped the project library each time it saw a version mismatch (painful, as B-Nilson rightly pointed out). Now uvr sync re-resolves the lockfile for the new R once, wipes once, and moves on.

- uvr cache clean got filters. --package sf or --r-version 4.4 (repeatable/comma-separated) lets you troubleshoot one package or retire one R series without losing the whole cache. Another B-Nilson request!

- Bioconductor just works in uvr add. Adding a package that lives on Bioconductor instead of CRAN no longer errors with "retry with --bioc" — uvr detects it, tells you, and adds it from the right channel (version constraints preserved).

- OpenMP-linked binaries fixed on macOS. Packages built with -fopenmp (Rtsne, mgcv, dotCall64, …) used to fail with "symbol not found in flat namespace" on uvr-managed R. The bundled OpenMP runtime is now loaded properly, and uvr sync self-heals older installs.

- A community code audit made everything more solid. gdevenyi filed a systematic 46-issue audit of the codebase (with file:line references — heroic work). Nearly all confirmed issues are now fixed across 0.4.1/0.4.2: cache integrity checks (sha256 on every hit), lockfile consistency for selective updates, honest error reporting where failures used to be silently swallowed, and a long tail of correctness fixes.

and much more...

This would have not been possible without the great help of many, special shoutout to https://github.com/B-Nilson for the endless testing and support and the entire group of users who have written code, filed issues, tested this, and loved it. One of the most rewarding aspects of this process has been building a community around this project ❤️ it's early days but so exciting!
