Tomorrow on The Pragmatic Engineer Podcast: Designing Data Intensive Applications with @martin.kleppmann.com

Yes, it's true! @brittanyellich.com crushed it in shipping a v0.1 version of a new community hub at atmosphere.community Features: @standard.site aggregation powered by @opensocial.community, group calendar, regional communities etc etc etc

made a thing i've always wanted for nodejs: easy-to-use worker threads w/ shared memory. all respect to piscina but the dx never landed for me. also first experience using @tangled.org for oss work and it rules. ci was very easy to set up with spindles and runs faaast.

We just set up shop over on surf.social, a new platform that combines Bluesky posts with podcasts, YouTube, RSS, and more — rolling it all into custom feeds. You can find us here: verge.surf.social vergecast.surf.social decoder.surf.social versionhistory.surf.social

Pleased to announce that an Authenticated Transfer Protocol (ATP) working group has been created at the IETF! Grateful to everybody who participated in the BoF and chartering process. Details on next steps and how to get involved inside. atproto.com/blog/kicking...

still vibrating from #AtmosphereConf. everyone was so brilliant and coooool 😭 we have something special here yall

About the Atmosphere I’m writing this from the beautiful UBC campus in Vancouver where ATmosphereConf 2026 is taking place. It’s a gathering of developers, researchers, and entrepreneurs who are passionate about keeping the... https://toni.org/2026/03/27/about-the-atmosphere/

Okay, so a little while ago, I was asked to run an office hours event, where people could ask me their questions on AT Protocol, OAuth, etc Here's that event: atmo.rsvp/p/thisismiss...

I will not be at the #AtmosphereConf this year 😭😭 -- in fact, I'll be out of the office until April 5 (after this weekend!) But I REALLY WANT TO HEAR FROM YOU IF YOU'RE GOING AND ARE BUILDING NEW AND INTERESTING THINGS. Dm or Germ or Signal or email me with any news! (Links on profile.)

We've got an updated protocol roadmap out, covering the next few months. Look forward to seeing folks at AtmosphereConf later this week!

The Atmosphere is a new open network. The features: - Your account works on all atmosphere apps - You can switch to a new provider with no fuss - Easy to make your own apps on it - Works great with personal websites And, Bluesky is an atmosphere app.

here it is folks! lots of details to still nail down, but this is roughly where our heads are at for the design of a permissioned data protocol give it a read and let me know your thoughts!

Thrilled to be working with @bad-example.com, whom you know from the excellent @microcosm.blue tools, on making the atproto network ever more resilient atproto.com/blog/introdu...

Some very exciting news - it looks like the working group for AT Protocol at the IETF has been approved! (though not formalized in the datatracker just yet) This is a big milestone in the standards process. But is also just the start of the actual process - years of meetings & work ahead!

buckets are out, spaces are in

the at protocol is amazing. i've read a lot about it and haven't made anything with it yet. macwright.com/2026/03/16/a...

Week 1 observations: toni.org/2026/03/13/i...

continuing to build up our permissioned data protocol! this one asks what a bucket actually is and where the data that constitutes a bucket is stored. it argues for maintaining the atproto ethos in the permissioned data protocol as always, looking forward to hearing your thoughts!

I started a short blog series to share my experience creating a custom feed for Bluesky — a pet project that started as “let's build a triathlon feed” and (spoiler alert!) now can be used for any topic : ) https://cuducos.me/building-a-custom-bluesky-feed-part-1.html

@jimray.bsky.team: "We're proud to be supporting npmx with a $6K grant as a part of our ongoing ecosystem support. (...) The atmospheric web is bigger than any one application, and projects like npmx are exactly what it looks like in practice" 💙 Thanks a ton, Bluesky team! Cheers to the social web!

I'm thrilled to announce that I'll be joining Bluesky as interim CEO. I deeply believe in what this team has built and the open social web they're fighting for. More here: toni.org/2026/03/09/c...

We're so excited to support @thisismissem.social's work bringing FedCM to the open social web! atproto.com/blog/working...

there aren't many folks who can bring such a full picture to the W3C on decentralized login the way @thisismissem.social will be able to. this is great news for atproto re: steps towards a browser-native login experience, and other ecosystems will benefit too. i will be following along closely!

one account wherever you go ☺️ your handle isn’t just for one app anymore ! we took @hello.pckt.cafe for a walk across the atmosphere

Almost 5k 🚀 let’s get there today - tell your friends! 🇫🇷 On passe les 5,000 aujourd’hui? Parlez d’Eurosky à vos amis! 🇪🇸 ¿Llegamos a 5,000 hoy? ¡Cuéntaselo a tus amigos! 🇩🇪 Schaffen wir heute 5,000? Erzählt euren Freunden von Eurosky! 🇳🇱 Halen we vandaag de 5,000? Vertel je vrienden over Eurosky!

We're rolling out a change in image format. If you see some images taking a second to load today, that's expected.

The blacksky.community web application now uses our own API servers to load posts, timelines and profiles. When data is missing (accounts on the edges of the network, outside of our primary community, etc) we leverage @microcosm.blue

Congrats to the team @tangled.org!

huge! congrats @tangled.org :)

I'm building on atproto because building infrastructure like "Drafts and Scheduled Posts for every atproto app" is easy as 1-2-3 and as cool as alf. Announcing alf, the atproto Latency Fabric: leaflet.pub/p/did:plc:3v...

🔴 LIVE https://stream.place/pfrazee.com And we are live with office hours!

new blog post on permissioned data in atproto! this one introduces "buckets", the protocol-level primitive for shared access control. I walk through two approaches that don't quite work and land on something that I think does let me know your thoughts!

It's been almost one full fortnight since our last one, we're doing office hours again this Friday. And we're bringing special guests to talk all about building on atproto. smokesignal.events/did:plc:lysq...

New blogpost about atproto It's not federation, it's not a p2p mesh. It's a secret third thing: practical. www.pfrazee.com/blog/practic...

Did you miss @zeu.dev teaching us about ATProto No worries! Check out our conversation on the Web Dev Podcast, then code along with us on Learn with Jason. WDP: codetv.dev/series/web-d... LWJ: codetv.dev/series/learn...

What even is the AT Protocol? @jason.energy and I talked about @atproto.com and what the future of social media can look like, where users are in control and developers are given more interoperability opportunities

yes! sync 1.1 leans into the end-to-end principle: end consumers (e.g. apps) perform their own verification. technically relays don't have to! but what makes a *great* atproto relay? a great relay protects consumers from garbage and network abuse, which is why indigo/relay verifies the events.

sync 1.1 made atproto relays dirt cheap. also... computers are fast.

the full PLC story relies on: - independent governance - public, formal auditability to stake its reputation - in case of emergency, credible exit even in the case described below, there is a story for auditability (see thread). plc read replicas shipped, governance and transparency logs ahead!

just added @standard.site support to my blog when I deploy a new version of my site, blog articles are automatically synced to my pds (npmx.social) ... and therefore immediately discoverable on any standard.site reader, e.g. @greengale.app ...

We've released a self-hostable reference implementation of a PLC read-replica service to make the Atmosphere ever more decentralized. @retr0.id has details on what this all means. atproto.com/blog/plc-rep...

We've been hard at work on a new website with new guides, better docs, more translations, even our very own blog. We think it looks pretty sharp, too. It's now easier than ever to just build things with AT Protocol. atproto.com

in atproto office hours folks asked about two-week session lifetimes for oauth public clients, such as SPAs. i spoke about a surgical little proposal to have our cake and eat it too: SPAs untouched but with client authentication! for those interested, here it is: github.com/bluesky-soci...

I can save bookmarks with @margin.at, file them in collections created with @semble.so, and both bookmarks and collections are visible in Margin and in Semble Oh, and if either Margin or Semble shut down, this wouldn't impact my data All of this dark magic is only possible thanks to AT Proto

hey we're really working on permissioned data! read the first in a series of posts i'll be doing about our design decisions along the way. this one is about our decision to not do an e2ee system

Hot off the internets — there's a brand new kid on the DASL block: Web Tiles! It's still early days, some key features are missing, and there are some rough edges, but you can publish tiles to AT and play with the idea! webtil.es

so, if you're on @tangled.org, we're there too! 🕸️ 👉 I just set up a read-only mirror of @npmx.dev for our friends there 🩵
