Creating a file is a pretty basic and conceptually simple task, that many applications do (whether they realise it or not – library code often does this too, at least for temporary files such as caches or for communicating between programs). So you’d think it’d be trivial to do correctly. Alas, it is not. ☝️… Read more
I sometimes forget that this is possible (and even more often exactly what the damn syntax is – kudos to vacawama in today’s case of this for reminding me with their StackOverflow answer). There are numerous other ways to write the above, but I think it is the most elegant. Inferior Alternatives More indentation, and… Read more
This is an elaboration of a post I made in a Swift Forums thread, SE-0419: Swift Backtracing API. The question was raised whether an official Swift backtracer should try to support code that doesn’t use frame pointers. Which immediately raised the question – in my mind – of if anyone is still using the “optimisation”… Read more

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. At [re]boot time (best I can tell), it resets /etc/hosts based on some random template it has (/etc/cloud/templates/hosts.debian.tmpl in my case, even though that… Read more
