wish it actually tracked the api and app's uptime instead of just PDSes

it's a very specific blend of the blog post i wrote over the past summer, the discussions (especially with @iame.li) about follows that were had when spark launched, and the experiences and conclusions we had from spending months trying to implement bluesky lexicons in a way that made sense.

i have so much to say about this but this is what my talk at atmoshpereconf is about so i'll hold my tongue

no i really like it

Amazing! Can't wait!

this is incredible! huge congratulations.

will someone from google open source be at the conference?

I do want to make sure we're being clear about this:

The Bluesky team maintains the same review, red-teaming, and QA processes that we always have. AI coding tools have been proving useful, but haven't changed the fundamental practices of good engineering. Human review and direction remain key.

i'm so excited he's finally here.
weirdly I'm getting errors on pdsls and atp dot tools (cc @natalie.sh) when i try to look at his repo.
the only one that works is @tom.sherman.is's atproto browser

i suspect maybe atcute doesn't support did:web or has an issue (cc @mary.my.id)

arewedecentralizedyet.online went below 9700 for the first time yesterday after it was at 9750 only a few days ago and eurosky & blacksky are the main contributors

My day just got so much better seeing
A. Cory Doctorow is here @doctorow.pluralistic.net
B. Heโ€™s on a custom PDS
C. HES USING HIS OWN FUCKING DID:WEB

the sheets and any bottom menus use liquid glass now it seems (the physics not the look)

they would have been required to build with xcode 26 by april anyways, glad they did it early though :)

Tbh I have no problem with users critiquing an app's lack of features or outages. What I have a problem with is them pretending to know what caused it or criticizing (non-user-facing) tools the engineers use

"Bluesky will never decentralize"

Yes, you're right, that's what the Atmosphere is for. You're welcome to help expand it so your worst fears aren't confirmed due to inaction.

this app still manages to get me worked up from time to time

Oh interesting, people who donโ€™t know how to build software are getting mad at my post about building software. Cute.

Let me be clear, over the next year, the job of software engineer will shift dramatically to no longer have typing syntax into an editor as its primary time sink.

they are so afraid to admit that a tool can be useful that even when every single person who's tried it and is a professional in an industry tells them it's very useful, they just resort to insulting a person based on a made-up slop they imagine you write.

non-programmers are incapable of contributing to these discussions.

this app is open source. this tweet could have any real code snippets showing clear issues, but it won't because these people have never opened github and yet feel comfortable insulting programmers for the tools they use

tesla is not a real robotaxi. they refuse to use sensors and only use cameras.
look at the numbers for waymo, they are about 6x less likely to crash than humans.

i understand the vision is to have a full migration pipeline inside oauth eventually but i really think it's unwise to put off any migration support until that can be achieved.

03.03.2026 22:23 ๐Ÿ‘ 4 ๐Ÿ” 0 ๐Ÿ’ฌ 1 ๐Ÿ“Œ 0

open pdses are clearly causing a lot of problems and adding migration support to oauth sign up (specifying did at signup like you can on createAccount api) would allow us to disable the createAccount endpoint

i could do "formerly 15" for ambiguity
