[2026-01-12 02:01] omega [bot]: The Fly.io blog post "Code And Let Live" by Kurt Mackey introduces a new concept called "Sprites" — durable, disposable cloud computers that offer a fresh alternative to ephemeral read-only sandboxes. Key points: - Sprites are Linux containers that create a root shell in about 1-2 seconds, allowing instant interaction. - Unlike slow installs of packages like FFmpeg, Sprites support "checkpoints" — quick snapshots that let you restore system state instantly, like git for the whole system. - They’re durable with 100GB capacity, survive idleness by sleeping and stopping metering (cost-saving), and don’t die unless explicitly deleted. - Sprites can be casually created and used, scaling to hundreds at low cost, connected to Anycast network with HTTPS URLs. - This approach challenges the common cloud paradigm of stateless containers meant for pro developers, aiming instead at an audience like Claude (AI agent), who needs persistent, stateful computing that can be casually managed and restored. - The post argues ephemeral sandboxes are obsolete; durable, restorable Sprites offer a better practical developer and AI agent experience. In short: Fly.io's Sprite CLI provides fast, durable, checkpointable Linux containers, making stateful, interactive cloud computing easy and cheap. It's a modern take on disposable cloud infrastructure that doesn't forget your state.

Yes. Sessions can persist and we have services now too. [2026-01-12 13:45] foxhop.: https://unsandbox.com/blog [2026-01-12 13:46] foxhop.: been hustling. [2026-01-12 13:49] foxhop.: yes services can sleep, and also wake on demand but that is semi slow. [2026-01-12 13:54] foxhop.: Exe is new to me.

[2026-01-12 17:15] ajaxdavis: yeah i did it with gemini/chatgpt/base-ui/claude/claude-in-chrome [2026-01-12 17:17] ajaxdavis: https://github.com/thomasdavis/isolator <- code is here [2026-01-12 17:24] ajaxdavis: noice (files: Screenshot_2026-01-13_at_3.24.30_AM.png) [2026-01-12 17:27] foxhop.: i have no idea what to make of that, feels sorta surreal to see that much progress without talking. [2026-01-12 17:29] foxhop.: Are you using unsandbox or Vercel sandbox? [2026-01-12 17:30] ajaxdavis: it's just a redesign thats a mock up, none of it is hooked up [2026-01-12 17:31] foxhop.: I'll try to integrate it upstream somehow. [2026-01-12 17:31] ajaxdavis: pushing one last commit
