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.

Also, I always figure Bluesky is a good place to go for random transit questions: surprised that the skytrain is driverless without planform screen doors—I always thought the two were necessarily linked. What’s the story there?

In Vancouver for #AtmosphereConf! So excited to chat with some fantastic developers (@pfrazee.com, @iame.li, @reedharmeyer.bsky.social) about building with @expo.dev on the AtProto. Saturday, 2:30PM, Great Hall South — be there!

Hey @fly.io! Would love if customers could manually increase their own machine limits ("i.e. I know what I'm doing"). Requiring an email to support is preventing us from taking advantage of fly's fantastic scaling :)

Support got back within 5 minutes on a Sunday afternoon. Pretty impressive stuff.

I’ve long said that a major factor in my choice of airline is WiFi. The fact that Air France now offers fast (and free!) Starlink means it’s now my usual go-to for flights to Europe. Fantastic work!

⚡ We teamed up with Meta to deliver precompiled iOS builds in 0.81/SDK 54. You get: ◆ Faster builds: Compile RN once per release ◆ Smoother integrations: Easier to add RN into brownfield apps ◆ Future-proof: Prepares RN for migration from CocoaPods to Swift Package Manager expo.dev/blog/precomp...

expo.devPrecompiled React Native for iOS: Faster builds are coming in 0.81React Native 0.81 introduces precompiled iOS builds, cutting compile times by up to 10x in projects where React Native is the primary dependency.

In the US, the gold standard is probably Amtraker, or asm.transitdocs.com. But Amtrak's terrible (undocumented) API means often a bad experience is passed on to the user. While Carto doesn't actually have location information on the trains, it manages to deliver a fantastic experience.

There are so many reasons to love the Paris metro, but one of them is how quick stops are. The doors are open for less than 10 seconds at some stations. This is what platform doors and high frequency enables! If trains are arriving every 4 minutes, missing a train isn’t a big deal.

Update: it's just okay. Not worth it for $90 IMO and the battery life isn't great. It's also much larger than I expected. But, I'm going to keep giving it a go and see what the one-week update is!

Ordered a tinypod (thetinypod.com) and will report back how it feels. I'm excited – I have basically stopped wearing my apple watch thanks to my Oura ring, but wish I could stop carrying my phone around. It *should* be able to do everything I want (Music, iMessage, etc.) but no YouTube or Twitter.

Currently transported back to the 90s on my United flight — there’s a credit card reader built into the seat back and they’re showing the trailer for “Clueless (1995)” which is wonderfully dated.

The court ruling in Epic v. Apple now allows iOS apps to include in-app links to external payment pages—with just your payment processor’s fee and no modal—if your app is distributed in the U.S. This blog post is about what this means for Expo developers: expo.dev/blog/mobile-...

For this build, I’m running Shimano Ultegra Di2 (R8170). Ultegra is in the upper-middle tier of Shimano’s offerings, with 105 being the lowest and Dura-Ace being the highest. Di2 means the shifting is electronic — rather than running a cable, the shifters communicate wirelessly with the derailleur.

Building a new bike and figured I'd document the progress here! Something I love about cycling is the standardization across the industry – with some caveats, most components are compatible with most frames. This build begins with a Pinarello frame, the K10s.

The groupset consists of most things mounted on the frame — the crank, derailleurs, brakes, shifters, chain, etc. There are basically three companies who build these parts: Shimano, SRAM, and Campagnolo.

The K10s Disc is the successor to the K8-S, my current frame. Designed for cobble, the K8-S features 9mm of rear travel, which makes it super comfortable. Even so, I've found it to be a great descender (it's very smooth) and also climb really well. It's surprisingly stiff, even with rear suspension!

I primarily ride in the South Bay Area, mostly in the hills east of the Stanford campus. Disc breaks will be a huge upgrade on the descents – more stopping power translates to more control and better cornering. They also mean I can run wider tires, which translates to an even more comfortable ride.

You are up to date.
