Show HN: TIL – a timeline file format with a spiral viewer and editor

Sun, 05/31/2026 - 6:22pm

Hi HN. til is a timeline file format and CLI with a web viewer and editor.

A timeline stores 3 main things: events, ranged events, and tags.

Events can point to external refs (URIs, UUIDs, etc; a ref is an arbitrary string) and also contain arbitrary JSON attributes. The idea is that the .til file works as a temporal index, where payloads, notes etc live wherever you already keep them.

I've wanted to build this for a while, mostly for keeping track of and viewing timelines that I find interesting (music, roman empire stuff, etc). This project has 3 main elements, which are all independent: the file format itself (binary, built with postcard), a rust CLI, and a web viewer + editor (react, with the parser compiled to WASM so the FE shares the same implementation).

Tell HN: Meta's AI support feature allows Instagram accounts to be stolen

Sun, 05/31/2026 - 6:11pm

If the AI support option is enabled for your Instagram account (it appears to be A/B tested for only a percentage of accounts), anyone can hijack it with little effort. Simply get on a proxy or VPN close to the account's region, then ask the agent to send a code to an arbitrary email address. Once you receive the code, pass it forward to the agent, and it'll provide you with a password reset link which you can then use to sign into the account.

Posting here for any Meta employees who may be reading. This flaw has been around for at least a few days and has been used to hijack over 100 high-value Instagram accounts. The correct patch would be to disable the AI support feature entirely for the time being until this is sorted and revert accounts and usernames that have been hijacked over the last few days. This is a pretty important flaw and it's currently being exploited in blackhat circles. The steps above are public knowledge in these circles and can be found trivially on Telegram.

Ask HN: Do you use Cloudflare bot protection? If so, why do you use it?

Ask HN: Do you use Cloudflare bot protection? If so, why do you use it? Did you stress test your servers and determine that you need bot blocking? Have you considered alternatives like anubis?
