NSImage is formally documented as largely not thread-safe: The following classes and functions are generally not thread-safe. In most cases, you can use these classes from any thread as long as you use them from only one thread at a time. Check the class documentation for additional details.

Every now and again I’ll go to do something really innocuous with an Apple framework, like disassemble it in Hopper or check the link headers. And every. single. time. I forget that Apple did some really weird shit in Big Sur, and removed the binaries. $ ls -lh /System/Library/Frameworks/AppKit.framework/Versions/Current/AppKit ls: /System/Library/Frameworks/AppKit.framework/Versions/Current/AppKit: No such file or… Read more
I don’t know how or why it is even installed – perhaps part of the provided Ubuntu image from my VPS host – but cloud-init (a.k.a “cloud-config”) is a bit obnoxious.

It prefers ImageMagick, as ImageMagick supports a much wider range of files, tends to be faster, and some assert that it produces higher quality files. ImageMagick 6 was superseded by ImageMagick 7 nearly a decade… Read more
This is just a little snippet that is quite useful for reporting when your GUI thread (the main thread / actor) hangs for a significant amount of time. There are numerous heavier-weight tools for analysing this sort of thing, but I’ve found that this simple monitor does what I need most of the time. You… Read more
Tonight I decided to give Kagi a try, after hearing John Gruber mention it a few times on Daring Fireball. I’ve used a mix of DuckDuckGo and Bing for over a decade now, and occasionally will still try Google in desperation. What I’ve noticed is a decade-long trend – accelerating in the last year or… Read more
I just read up a bit on io_uring, prompted by a Swift Forums thread relating to it, and it made me laugh. To a lot of people it’s an amazing new[ish] high-performance I/O system for Linux. Which it is (albeit with some serious security concerns, apparently). A lot of people are very excited by it.… Read more
