This has always been a Bluesky-first campaign. But as of today, we will no longer be using Twitter. At all.

And I'm calling on other candidates to follow suit.

the government website to view the epstein files is awful (i assume on purpose) but @rhys.dev made a super fast & searchable viewer

Bluesky gained that for me without any mind games and without forcing itself on me at every chance through all the other apps that company has.

Ah that's crazy, it's almost like Threads picked up the decentralization messaging when they launched so they could neutralize the Atmosphere

Leaflet's Atmospheric Advent Almanac, Day 18

LAUNCH [3] — Bluesky thread viewer

You can now browse Bluesky threads right in Leaflet, both post embeds and quotes/mentions!

Nice for more seamlessly bringing in social context…try it with some examples in this very post! cc/ @erlend.sh :)

check out osaurus.ai if you're on mac. it's leagues better than ollama because it's actually made for apple silicon and runs on mlx

accidentally hit the "im feeling lucky" button in chatgpt atlas and it decided to do a "roast of my tech stack"

surprisingly it was actually pretty good, especially this part.
"every outage is philosophical" hits so close to home it hurts

This is incredibly nice and really great for new projects but I would love if some attention was paid to making consuming the pure relay more ergonomic. Namely, server-side collection filtering. It sucks if you want to consume the firehose you have to consume every single event.
finally landed it!

Tap is your all-in-one sync tool for the Atmosphere: webhooks, backfill, filtering, signaling collections, no cbor/msts/signatures/cursors. this thing's got it all!

give it a go and let me know what you think & if you run into any issues
