Some nice shots of the beautiful Norbauer mechanical keyboards that were awarded as prizes for the 1st annual Expo App Awards.
I made a Chrome Extension that advises you if you play 82-0 . It works pretty well. chromewebstore.google.com/detail/82-0-...
We weren't planning for Healthcare to become a top Expo vertical. But here we are. 7,200+ health apps shipping on Expo & a big chunk of new signups now come from clinical teams. We're proud of this trend and we built a new page to help health eng teams evaluate Expo: try.expo.dev/healthcare-b...
Expo for Healthcare
Expo is an open-source platform for making universal native apps for Android, iOS, and the web with JavaScript and React.

This was ridiculous and makes me angry. This referee decision should definitely be reversed. The videos of the races Brown won are incredibly anticlimactic. "When is the unsportsmanlike behavior going to happen?" Just bizarre.
Mallard Creek runner Nyan Brown was disqualified for raising his hand in celebration after apparently winning a relay race Saturday.
I’m pro-freedom, pro-law and order, pro-limited government, and pro-the Declaration and the Constitution. And so today I’m a Democrat.
You need speed. Slow builds kill momentum. We're addressing this from every angle: ◆ Dozens of new M4 Pro/Max Mac Minis added ◆ Compiler caching, Gradle caching, prebuilt binaries ◆ Prebuilt XCFrameworks ◆ Fingerprint workflows so you only build when native code changes expo.dev/blog/build-f...
Build fast, no matter what: how Expo is optimizing for speed (and how you can, too)
New M4 Mac Minis, compiler caching, and prebuilt binaries are speeding up EAS builds. Learn how to build less often with fingerprints and OTA updates.

🔥 Chain React 2026 Speaker Lineup 🔥 Some of the biggest names. From some of the biggest companies in React Native. We’ll be announcing speakers right here 👇
Join me and hundreds of React Native developers at the 2026 Chain React conference in Portland, Oregon! chainreactconf.com
Working remote is great day-to-day, but over time you really do miss your coworkers and colleagues in the industry. Especially the React Native community. I hope y’all take advantage of the opportunity to come hang with us! Get your tix now: chainreactconf.com
🎤 Announcing: Charlie Cheever If you're in tech, you know @ccheever.com Charlie's the co-founder of @expo.dev and one of the biggest driving forces behind React Native!! Charlie's joining us live in Portland for Chain React. 🎟️ ti.to/chainreact/c...
Back when Bluesky first launched, there was a ton of momentum about leaving Twitter. But it was hard to migrate, hard to crosspost. Too many people didn't make the jump. Software needs a critical mass like social media, and now the wind is in @tangled.org's sails. I hope they get it right.
hey @tangled.org... this might be a great time to build some tools that make it easy to try hosting your repo on Tangled, or at least write a blog post about how to move over.
Seth is different. He can zoom out & see all the layers of a problem. He knows what to say. And what to build. And how to build it. What's possibly most impressive is that he delivers all this perspective with warmth and joy. It's infectious. We're lucky to have him! expo.dev/blog/seth-we...
I joined Expo.
After leading React at Meta and co-founding the React Foundation, here's why joining Expo felt like the natural next step for helping developers ship faster

🥳 We raised some money. Expo is the best it's ever been, and this round of funding will help us get a lot better. With this money we can go faster on the things that matter: faster builds, smoother native integrations, and better e-2-e DX. Charlie wrote about what's next: expo.dev/blog/what-ex...
It’s amazing to hear that Expo were successful with their Series B - congrats! 👏 There’s so many awesome things coming out of their stables at the minute, just look at the release notes on the past few SDK updates. Excited to see what’s ahead and can’t wait to play around with Expo Agent too 🤓

From my game’s biggest revenue day to patching production bugs and shipping EAS updates. Building your own product is a rollercoaster 🙃

When the Supreme Court allowed immigration agents to consider race during sweeps, Justice Brett Kavanaugh said that citizens shouldn’t be concerned because agents will “promptly let the individual go.” For these Americans, that wasn’t true. (Published Oct. 2025)
More Than 170 U.S. Citizens Have Been Held by Immigration Agents. They’ve Been Kicked, Dragged and Detained for Days.
The government does not track how often immigration agents grab citizens. So ProPublica did. Our tally — almost certainly incomplete — includes people who were held for days without a lawyer. And near...

It's sort of funny when codex/claude give you time estimates of how long something should take, like 2 weeks, and then does that thing in 25 minutes.

happening this morning in Minneapolis -- ICE agents drawing guns on observers. I reiterate again that it is only a matter of time before DHS kills more innocent people in Minnesota. Congress needs to shut this shit down right now.
This morning, I recorded a video on TikTok about why DHS’s arguments for the power to enter homes without judicial warrants in immigration cases are bunk. Nine hours later, TikTok still says my video is “under review,” and can’t be shared. Well, here’s a link: georgetown.box.com/v/Vladeck-IC...
ICE is straight up executing people for no reason other than to create fear. We have to get it disbanded and prosecute the leadership and its thugs.
