  • You write one kind sentence. I donate a dime. A blockchain makes sure I do.
    Go 1.26 standard library, modernc.org/sqlite for a pure Go SQLite, and solana-go for the RPC client, transaction building and the SPL Memo instruction. React 19, Vite 8, TypeScript 7 and Tailwind CSS 4 on the page. Alegreya and IBM Plex, self-hosted through Fontsource. Fly.io for one machine and one volume.

  • Best alternatives to Heroku in 2026
    Fly.io opens up two things Heroku keeps at arm's length: real multi-region deployment and full control over the runtime. Heroku's Common Runtime offers two regions (US and EU), and Private Spaces gets you one region at a time from a wider list. Fly runs Firecracker microVMs across eighteen regions on six continents, and replicas can be pinned to specific cities. If your Heroku app has global users and you've been... - Source: dev.to / about 2 months ago

  • It Worked on My Machine (Literally)
    The tunnel was never meant to be permanent (it runs off my laptop, and the URL changes every time it restarts), so the next step was deploying somewhere real. I built the Docker image for Fly.io, set my username, and shipped it. - Source: dev.to / 3 months ago
