trueno¶

A small uploader that runs just by dropping it onto a shared rental server. It takes the form of an old-school CGI uploader, with no extra software to install.

Design notes: a design where the URL tells you its lifetime, no DB thanks to sidecars, two-tier authorization

The articles are a record of how it came about as the uploader platform for 6umi, up through adding the classic uploader UI.

Released trueno, an uploader you just drop onto a shared server

I built trueno as the storage backend for 6umi.net's uploader (a.6umi.net). If you put it as a CGI on a shared rental server you already have a contract for, you don't need to rent separate object storage. Since I switched 6umi's storage to Cloudflare R2, trueno, which had been behind a.6umi.net, no longer had a place. To keep it alive on the shared server whose contract is still running, I moved it to a2.6umi.net, and at the same time gave trueno, which had only been an API, an uploader page you use from the browser, and released it. The code is at https://github.com/kimari-s/trueno (MIT).
