Very much looking forward to talking about the conceptual origins of SwiftUI and how that makes it an effective and versatile UI framework!

Act different. What kind of community do we have if we do nothing?

This is not normal. Business as usual cannot continue. But what that means, exactly, is up to us.

Since Last May, ICE Officers Have Been Told They Don’t Need Warrants To Enter Homes The thing afforded the highest protections of the Fourth Amendment is a person's home. This isn't even a controversial statement. It has been that way ever since this amendment was ratified. But, under Trump, we're constantly seeing that the administration considers all rights to be privileges -- something only granted to people this administration likes. The Associated Press has obtained a blockbuster leak…

The US land lost in Canada The Northwest Angle is the northernmost point of the continental United States, and one of the last American frontiers.

They tried that for just one piece. But it stayed under US control.

I’m Probably About to Be Banned From CNN — But Someone Has to Say This About Scott Jennings There are times when you need to tell your friends that they are committing a grave mistake, even if they resent you for telling the truth.

Abolish ICE Before They Kill Again, Impeach Trump & Noem Before They Incite More Murder Renee Nicole Good was a 37-year-old award-winning poet, a mother of a six-year-old, and a wife who had recently moved to Minneapolis. That all ended yesterday when a masked ICE agent murdered her in broad daylight, shooting her multiple times at close range in the head. She had stuffed animal toys in the glove box of her SUV that rammed into another car after she’d been killed for no reason at all.

Using imagery online of the shooting by an ICE agent in Minneapolis, we’ve created an animated sequence which highlights the approximate positioning of officers and vehicles at the scene. The red dot represents the agent who fired the shots. Yellow dots are other agents who arrived at the scene.

I think the timing for this will not work for me to attend in Berlin on that day. But let me know if there is anything I can do to help with any citations or references.

I'm actually thinking about conferences that might be good fit to present the Immutable Data architecture. Would BOB be a good fit? We see the architecture as inspired by JS and functional programming but for now we are just focusing on deploying to SwiftUI. Would that talk make sense for BOB?

You could also reference the first chapter of our Immutable Data Programming Guide that talks about the origins of Flux and Redux and how this evolution is different than the evolution of UIKit and SwiftUI.

I would definitely reference the talk from Jing Chen that talks about the origins of Flux and how this evolved as an alternative to MVC.

And if you are discussing Flux then I also think it is fair to go back and discuss CQRS which built first many of the ideas that Flux shares.

So just now reading the paper… I see some interesting ideas but also some missing pieces. The paper discusses ReactJS but fails to discuss the Flux pattern. I would really want to include Flux in any discussion of declarative UI state management.

Manuel Chakravarty In this episode, we talk to Manuel Chakravarty - specifically, his work on the ghc backend such as data-parallel Haskell and the FFI and how that work segued into type system design. We also discussed Manuel's perspective on Haskell from the language design of Swift.

I’m on the latest episode of the @haskellinterlude.bsky.social talking about GHC, the FFI, type families, parallel programming in Haskell and also about the relationship of Haskell and Swift: https://haskell.foundation/podcast/72/

But it's a Canadian Entity running an ad in the US with content from the US public domain… so it's different than a Canadian Entity running an ad *in Canada* with content from the US public domain.

Copyright status of works by the federal government of the United States - Wikipedia

It's possible that the US Government can claim that the Radio Address is *not* in Canadian public domain… but I'm not clear if that means the Reagan Foundation can sue Canada *on behalf* of the US Government.

GitHub - mattmassicotte/Empire: A local persistence system for Swift A local persistence system for Swift. Contribute to mattmassicotte/Empire development by creating an account on GitHub.

It started as a toy, but Empire has turned into the most complex package I've worked on. Macros, parameter packs, very tricky concurrency and generics. And now I'm looking at lifetimes and Span. Don't fully understand them yet, but I now get why it exists.

Appeals Court Subtly Lets The Trump Administration Know It’s Just Being Racist By Demanding An End To Birthright Citizenship It's not enough to go after the "worst of the worst." It was never a sustainable effort, what with migrants committing fewer crimes than natural citizens. The attempt to rid the country of as many non-white people as possible under Trump always had to go bigger. It has become ICE raiding swap meets and Home Depot parking lots because that's where the non-whites are at.

Omg. My app is #3 in the paid AppStore charts in Germany today. #1 in payed education charts. 🤩🤯😱

(It’s a timetable app for vocational students in Lower Saxony, and it’s payed so a bit easier, schools currently start here so that’s why, ranked before but never that high.)
