Introduction to AT Protocol
Walkthrough of the various parts and concepts in Bluesky's AT Protocol (ATProto), the types of servers involved and how it all fits together
mackuba.eu
My "Introduction to #ATProto" blog post that I've been working on for some time is ready π It goes through things like records, lexicons, DIDs, then PDS/AppView etc. and how it all works together. Let me know if anything is wrong!
More parts later, with the Fedi comparisons & misconceptions etc.

's' or 'k' which have multi-byte case fold variants), we should

optimization at all, causing severe performance regression

Yay, looks like the regexp performance regression in Ruby 4.0 is fixed! π #ruby #rubylang

If the token is not JWT, is there any way to tell if it's expired or not before just trying to use it?

So here the access tokens are for 2h and refresh tokens for 3 months, and when you refresh (likely after those 2 hours) you get both replaced and the refresh token is again for 3 months from now, moved ahead. (IIRC in OAuth the refresh token has a permanent expiry time that isn't pushed ahead)

Also, it's possible to decode the tokens from base64 and then from JSON, and look at the expiry timestamps there: (this is issue time + expiry time for AT & RT before and after refresh, notice that everything is offset by 40s in the second section)

For app password, IIRC access token is 2h and refresh token is "very very long"

I *think* this should be more or less that, unless it was updated again later: docs.bsky.app/blog/oauth-i...
OAuth Improvements | Bluesky
We've been making improvements to the end-user and developer experiences with atproto OAuth, and wanted to share some updates.

And it's the other way around, access token is short, refresh token is longer lived

I think the answer is very different for OAuth vs. app passwords, might be why you're seeing different answers

I can't tell if this is a bot, or an actual FreeBSD nerd somewhere in Switzerland who stubbornly refuses to update to a Firefox newer than 3.6.8 because it breaks their setup and they would need to recompile the kernel or something

New: page width β set maximum page width in Leaflet!
Great for published blog layouts *and* even just for docs & drafts, e.g. to have multi-column view when editing subpages!
Set max width in your theme, from 320β1200px, with a couple presets *or* exact value e.g. to match an existing site β¨
