I’ve been exploring SwiftData lately, and I’ve been unpleasantly surprised by how many sharp edges it has. I’m going to try to describe some of them here, so that hopefully others can avoid them (or perhaps be dissuaded from using SwiftData to begin with). I’m using Xcode 15.0.1 (Swift 5.9) on macOS 14.1 (Sonoma). Background… Read more
Hardly news at this point, I guess, but just in case you’ve missed it: you cannot use the iPhone 14 Pro’s satellite communication functionality outside a very limited number of geographical regions (mainly the U.S. mainland). e.g. I thought I’d give it a whirl as I was flying out of Houston, out over the Gulf… Read more
After the horrible experience just acquiring, installing, & configuring a basic Raspberry Pi, I was anticipating much effort – likely ending in failure – to get Swift working. I was pleasantly surprised. There are multiple ways to do it, apparently. One would think that there’d be the correct & working packages already available through apt,… Read more
For a couple of little home projects I need an always-on computer. In an ideal world, perhaps, this would be something like a Mac Mini. Powerful [enough], easy to install & maintain, runs anything & everything (including anything Linux through Docker or at worst a straight VM). Unfortunately, Mac Minis are surprisingly expensive – even… Read more
Yet another example of a really bizarre macOS bug that’s pretty inexcusable as a test escape, given it occurs with the default installation settings on a completely clean OS install. In short, the Mojave update installer does not work (on High Sierra at least) if you have ‘Optimize Mac Storage’ enabled for iCloud Drive (System… Read more
I’ve been struggling since Mojave came out to deal with it’s over-bearing expansion of SIP (“System Integrity Protection”), which is basically a super-root notion that blocks access – even to root – to lots of basic parts of the system, including obvious & mostly sensible ones like /System and /Library, but also less usefully things… Read more
I’ve been using ffmpeg to trim clips from a trail camera, as most of the time there’s only a few seconds of anything interesting in frame out of the 30+ seconds of video it records each time, but I don’t want to re-encode them and lose video quality as a result (or balloon file sizes… Read more
