Boring Todo.
Toodoom began as a weekend idea after noticing that every simple tasks app had turned into a dashboard for teams. We just wanted a gentle place where my wife and I could share an @shopping list, keep track of @household fixes, and scribble personal notes. The result is a shareable, offline-first desk that feels like a calm gradient garden. My wife and I use it every day now. Switch between notes and tasks, drop in #tags, assign @categories, and keep life admin tidy without corporate bloat. Try the hosted demo at toodoom.vercel.app.

A fast compressor/decompressor.
Snappy is a compression/decompression library. It does not aim for maximum compression, or compatibility with any other compression library; instead, it aims for very high speeds and reasonable compression. For instance, compared to the fastest mode of zlib, Snappy is an order of magnitude faster for most inputs, but the resulting compressed files are anywhere from 20% to 100% bigger. On a single core of a Core i7 processor in 64-bit mode, Snappy compresses at about 250 MB/sec or more and decompresses at about 500 MB/sec or more.
