Damn, Muse is really quite good. #impressed

Checked in to Farringdon (Elizabeth Line), 4 Lindsey St, United Kingdom Yeah, fair enough. See on Swarm

Also, I'm not buying a #Deutschlandticket to save money (I'm 99% it'll cost more) but to avoid the completely inscrutable and most ridiculous apps ever that they force you to use to buy regular tickets. It's just insane, they want your name, address and an account to buy a single tram ticket there.

Buying a #Deutschlandticket is the most German thing ever. You need a passport + selfie style ID verification to buy a _train ticket_. In Britain, I could get a mortgage with less scrutiny and hassle...

The winning design. 🇪🇺💶

Solar's sharp rise continues. As of April 2026, global solar capacity now exceeds 3 terawatt. 1 gigawatt → 1 terawatt: 20+ years 1 terawatt → 2 terawatt: 33 months 2 terawatt → 3 terawatt: 19 months

What a night for England. You could hear London roar in the dark. Quarter-finals, here we come. ⚽

NEW BLOG FOR YOU Google's energy consumption numbers in their new climate report are mind-blowing. 2 years ago they flipped from linear to exponential growth, and their climate impact is blowing out, too. A WILD testament to the obscene bloat and waste of GenAI: ketanjoshi.co/2026/07/01/g...

HUGE launch! AWS Lambda MicroVMs - Isolated virtual machines which can run tasks or sessions up to 8 hours. It’s like Lambda and Fargate had a baby, and it inherited the best genes of both. aws-news.com/article/2026...

Whoa 😨

Vapor 5, alpha - release cut live by @0xtim.bsky.social! 🎉 #swift #vapor

Talk about few lines and big impact: This fix should finally the dreaded "error: '<dep>': Couldn't check out revision '<sha>'" failures seemingly at random when using SwiftPM. github.com/swiftlang/sw...

When you draw a stroke in Goodnotes on the web, you get the exact same curves and ink flow as on iPad, because it’s literally the same Swift code running on both. ✍️ Goodnotes engineer Yuta Saito shares how they built it with Swift and WebAssembly: www.swift.org/blog/bringin...

Ehhm, this cupboard _hinge_ has a website like some cutting-edge tech product. It's quite hilarious actually: www.grass.eu/en/products/...

It really looks like Anthropic can become profitable this quarter. I did not expect that last year. I think @simonwillison.net got it right: Claude Code & Codex have found product market fit. Enterprises are paying real money now! bsky.app/profile/jwei... simonwillison.net/2026/May/27/...

New blog post: NHS Goes To War Against Open Source https://shkspr.mobi/blog/2026/05/nhs-goes-to-war-against-open-source/ The NHS is preparing to close nearly all of its Open Source repositories. Throughout my time working for the UK Government - in GDS, NHSX, i.AI, and others - I championed …

Swift 6.3 has landed! 🚀 This release brings community-driven Android support into the official toolchain, along with major improvements to C interoperability, the build system, and embedded Swift. Read more: www.swift.org/blog/swift-6... #AndroidDev #iOSDev

Western carmakers are retreating from EVs just as oil hits $100 a barrel. The parallels with Detroit in the 1980s are striking. They ignored fuel-efficient Japanese cars. Now they’re ignoring Chinese EVs. BYD just unveiled 600-mile range and 250 miles of charge in 5 minutes.

The Swift Performance team isn’t *my* team, but they’re in my hallway. Or in London if you’d prefer. They’re looking for an engineer who’s not afraid of optimizers. jobs.apple.com/en-us/detail...

This is one of the strangest and most screwed-up stories I’ve worked on. www.londoncentric.media/p/tiktok-lon...

Good day! Inspired by thehftguy.com/2026/01/22/d... I took off my phone sockets to check what's behind. Turns out: CAT 5e! Found three separate cables, previously daisy chained. Ordered RJ45 sockets to replace phone sockets and undid daisy chains. Soon Ethernet in the flat, psyched!

Quite a few groups seem to be rather successful making many of us believe the opposite. So please note! Some things are getting meaningfully better.

FOSDEM, the legendary open source gathering in Brussels, is coming soon, and we'd love to see you there! We've got multiple talks on Swift plus a pre-FOSDEM community meetup. Whether you're a longtime attendee or new to the event, come say hi! 👋 swiftlang.github.io/event-fosdem/ #FOSDEM

Happy New Year, @swift.org crew! So happy to be back, I hope everyone enjoyed some time off.
 If you're looking to catch up on Swift news, check out the December digest: www.swift.org/blog/whats-n... and let me know what you think!

What should we call wholewheat (partially rye?) bread? I guess only Germans like that, so let's go with 'German bread' 😅. It's really yummy btw!

👏 Super cool to get Swift on the server showcased at reInvent

🎉 10 years of open source Swift! A decade ago today, we opened Swift to the world with a simple blog post: swift.org/blog/welcome What's grown since—thanks to an incredible community of contributors—has been extraordinary. Here's to the next ten years. 🧡

We'd be happy to see you at the inaugural Swift for Wasm Community Hour on 3rd of December! More details in this post on Swift Forums: forums.swift.org/t/swift-for-...

⚙️ Swift progress on embedded Swift, for memory-safe, fast code in resource-constrained environments. The latest updates are coming to Swift 6.3, and you can read more here: www.swift.org/blog/embedde... #IoT

Ever since the parliamentary wars of Brexit, the UK media and Westminster bubble craving for drama seems to have increased exponentially. What is technically still a relatively 'new' Labour government with a huge absolute majority is already (portrayed?) as fighting with its lasts gasps.

Very cool to see AWS and the Swift community work on this together aws.amazon.com/blogs/openso...

Observability is the key to understanding how your system performs and where problems are occurring. Moritz Lang and Si Beaumont gives us the run down on how it works in Swift! www.youtube.com/watch?v=HSxI...

Isn't that too beautiful? PM2.5 of an overnight pyrolytic oven clean starting at 1am. Still woke up at 3am on account of bad air, despite closed doors and open windows in kitchen...

It's been an incredible year for the conference. We had attendees from 6(!) continents come together for an amazing 3 days of workshops, talks and meeting each other face to face. Thank you to all the volunteers and speakers, it's been truly special

The new Swift configuration API makes the most of Swift's type checking and expressivity to make it eady to solve common config tasks. @czechboy0.dev walks us through its features @serversideswift.info forums.swift.org/t/introducin...

2025 - that's a wrap #swiftlang #serversideswift2025

#ServerSideSwift was so great. Fantastic to (re)connect with people from literally all over the world. Loved the very positive energy and the buzz around all the new stuff & maturity refinements around the existing tech. Most importantly thank you @0xtim for putting up this amazing show again!

Dropped my last coffee beans on the floor this morning. Was desperate enough that I picked them all up and made a coffee. Guess it's 99% arabica & 1% random dirt 🙈

Ever wonder how to write safe and fast code to run on your server ? Ever considered the open source Swift programming language ? Maybe it's time
