Swift Testing was updated to support Embedded Swift on `main` so of course you know what that means

is anyone else kinda glad that claude speaks in such a distinct, dense, inhuman prose style? it’s probably better if robots sound like robots, and it means humans have less incentive to pass it around to other humans

To add: - This can make the XY problem worse, because people will dig deep on Y without asking the team that can recognize when they should be doing Z instead

Last year, my team shipped a Swift rewrite of Apple's TrueType hinting interpreter. The new code is strictly memory safe, relentlessly tested, and faster than the C code it replaced. This year, it is my pleasure to ship it for a second time—now as an open source package—and to share our experience!

One of the best things I did when working on a Mac app was use a 1x display. You'd be shocked how many apps have simple pixel rounding errors.

South Carolina learned 35 years ago that easy access to gambling is a deeply corrupting influence on society, and learned 25 years ago that ending it basically immediately improves lives without any downside. www.goupstate.com/story/news/2...

Did a 5 day glassblowing intensive course since I have a month between jobs. I cannot adequately express just how helpful it’s been to get incredible instruction + at least 20 more hours of studio time. Pictured is Day 1, then day 2, then day 4. Straighter, taller, thinner, and more consistent.

Three hand-blown glass cups. The first one is short, thick, and very askew. The second one is much straighter, taller, and slightly thinner. The third one is much straighter still, much thinner, totally straight, and has a handle.

I’m quite excited today. Why? Because I got to delete 3500 lines of custom navigation (like 5 different navigation bars) and replace them all with system navigation. Good riddance!

My friend and I used to make a YouTube video series that gained a cult following back in ~2008-2012 and has a TV Tropes page. I used the money from YouTube partner revenue to buy my first Mac, which started my career.

Swift footgun: Dictionary.updateValue(forKey:) and Dictionary.removeValue(forKey:) return the old value, which means if you have nested collections, this will frequently cause a COW. Use the subscripts accessors.
