There are 300K+ views on Youtube of my talk! I've never had a talk get this amount of traction. It's confusing as I've been speaking/writing about this for years. Somehow the stars aligned this time. Upside is that I've had lots of interesting conversations with folks because of this.

Our MCP is now in beta! If you try it out and have feedback let us know.

Announcing atproto.science! #ATproto has huge potential for supporting new ways of doing research, so we started @atproto.science to help bring together researchers, build community, and explore what's possible when science meets cutting-edge open social network protocols! 🧪 >

fun lil project for the last day before christmas this one goes out to everyone that put up with our shitty dx for the last couple years 💙 github.com/bluesky-soci...

ahhhh spent a few days doing super complicated prototypes that didn't feel right and then a throwaway two sentence "how about we try this thing" prompt gave me the first good one

someone should write about this

Oh hey, come work with me! We're seeking an earlier-career front-end dev who is able to work in-office (multiple US locations). Check it out if you have interest and experience in: #designsystems #CSS #a11y #webcomponents adobe.design/jobs/job-pos...

yea honestly i tried reading about publishing lexicons in the official docs and i felt like the docs just want me to reverse engineer whatever they're saying back into human language. hard pass. same feeling about permission sets docs.

Two weeks off work means I'm bound to be tinkering. Thinking of building a little PDS that runs on a Cloudflare Worker. Anyone tried this? It should be a good platform for atproto stuff.

I think this is far enough along to post about now pegasus, a pds implementation in ocaml, ~feature parity with the bluesky pds (minus app passwords because those are gross) repo includes various other atproto-relevant libraries in ocaml for interested sickos tangled.org/futur.blue/p...

thanks to claude code i might actually ship the thing i wanted to make back in 2021 but didn't have the patience for. incredible time for people with vision and skill but low execution velocity

If you’ve attended JS/CSSConf EU, it wouldn’t have been the same without @lukaszklis and now he needs your help: his family home was devastated in a fire. I know times are tough for all, but if you can, please help turn this nightmare into a community miracle. 🙏 front-end.social/@fox/1157439...

what an embarrassing self-own by Chrome for Developers team

A personal recap of 2025. It was a year of a new style of engineering. Left some ideas for what might come next. lucumr.pocoo.org/2025/12/22/a...

I made something new: an eslint plugin to validate your npm ecosystem lockfiles! It supports npm, pnpm, yarn, bun, and vlt, and it's already helped find a supply chain security attack vector inside a fortune 500 tech company. www.npmjs.com/package/esli...

starting work on something exciting (maybe)

A new promising experiment with the way For You works has started: leaflet.pub/9a8bef7f-c39...

Yeah thats where we’re going The 2026 goal is to make The Atmosphere an idea that lives outside of Bluesky, as its own larger movement

it's funny to read claude thinking mode output. when it works well, it's always - starts with a few paragraphs that directly make sense - starts writing down some concrete ideas and directions - ... - "the emerging framework centers on actionable insights..." - ... but somehow comes out good

It's really sad that Chrome laid off one of the world's best CSS developer-designers, and now they have to fake demos of web features. youtu.be/d8J0vs-bEPE?...

Thinking about a flashcard based language learning app on the at-protocol

!!!

yea. i wish bluesky branding could somehow climb out of that hole but i don’t see how at this point

fwiw everyone should read en.wikipedia.org/wiki/At_sign.... includes “monkey tail”, “snail”, “dog”, and “crazy A” something to keep in mind

thinking of adding server code highlight per chunk to rscexplorer.dev

my claude code often gets stuck when it runs dev server or similar and then for some reason just waits forever on it. is there a way to teach it to never get stuck

Per my cofounder the naming goal should be something like email It’s simple and neutral: mail, but e-lectronic So staying close to the @ feels smart - it’s the universal form of identity on this thing we call social media

i should say “sing in with your AT handle” is easily my second favorite. sounds exactly like @ handle, but clear tie to AT and visually different doesn’t require so much arguing, capitalizes on AT wordplay but it needs to link to normie explainer etc

Okay we added this! Thread viewer now has a way to collapse / expand nested threads ✨↕️

really enjoying tools.slices.network experiments. write directly to an html file, no build tools, deploy to CDN. it's great for lexicon exploration because you don't have to commit to a domain, just use your subdomain. in a few hours i made a fully functional AT bug app! tangled.org/slices.netwo...

In which i offer to facilitate a research project to explore atproto ecosystem brand and user experience needs discourse.atprotocol.community/t/research-p...

I think that both Ghost & Wordpress have made a pretty grave product error integration AP over ATProto, but I understand how they got there, especially if the integration was lead by technical teams and not product teams. Does make me wish for a special projects person like @emilyliu.me used to do

I'm leaving @tldraw.com to enter the world of contracting. From January, I'll be prototyping contributor tools at @wikipedia.org My next availability is June!

Last week we released Tap, a tool to help you sync the Atmosphere, and it got me thinking about how revolutionary backfillability really is.

Threads is effectively shelving their fediverse integration, after it saw marginally little use Zuck has played the game well, harming both open protocol movements while growing his platform, getting good PR and distracting regulators connectedplaces.online/reports/fedi...

fucken lifesaver

Guilt trips and moral high grounds are the two worst sales strategies imaginable. Understanding "how people stay on ___" requires both sociology and empathy! Perhaps changing behavior _at scale_ is more of an organizing problem than a sales problem anyways.

in case you missed it: yesterday i wrote about a new open source tool i made, called RSC Explorer. it lets you interactively step through how the React Server Components protocol works directly in the browser — no server needed.

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 :)

what could help a lot with improving understanding of the ATmosphere/ATProto is if the largest atproto app (@bsky.app) would start referencing the ecosystem, protocol, or framework in-app so normies can start to understand better currently that context/educational cue is basically nonexistent?

fantastic article “two kinds of vibe coding” the part on testing is particularly insightful davidbau.com/archives/202...

also it is so much EASIER to make comprehensive tests now if you know what you’re doing. in my three vibecoded projects i made the kind of tests i’d never bother to do before. and they saved my ass many times you do need to steer it to test the right things which requires some experience and taste

ooooh, new @revolution.social pod with @jay.bsky.team!!! www.youtube.com/watch?v=p0O4...

i wrote about my new hobby project overreacted.io/introducing-...

yea the beauty of the web is everyone can literally do their own thing and see what sticks

plenty of fixes deployed to rscexplorer.dev, but mostly i just feel a lot better about the code itself

i like this one as long as it links somewhere

the funniest thing about "this is not AI, this is machine learning and it's good!!!" replies is that ML is a subfield of the broader AI field, and the disliked "AI" is a product of that exact subfield
