Your system has run out of application memory HUR HUR HUR

Screenshot of the macOS dialog saying "Your system has run out of application memory"

I hate this dialog with the fire of a thousand suns. When this appears, it basically means one (or both) of two things: Quitting any of the listed applications is rarely the correct move.  It’s often enough the case that none of them are the root cause, and you can kill all of them if you… Read more

iOS Family Sharing users cannot mix authentication schemes

Apple supports two styles of two-factor authentication, that they call (and distinguish as) “two-step” vs “two-factor”.  “Two-step” is their older method, though functionally they’re basically equivalent. If you have multiple accounts on a Family Sharing arrangement, and some use “two-factor” while others use “two-step”, you’re in for a bag of hurt. For example, any time you change… Read more

#if DEBUG in Swift

Sigh. The Swift team give an impeccable impression of a group of people who’ve never actually tried to use Swift. An incredibly basic compiler task is to provide code a way to distinguish between debug & release builds, in order that it can behave accordingly (e.g. change the default logging verbosity, change asserts from fatal to… Read more

EXIF metadata stores random gibberish for dates & times

Warped clock face spiralling ever inwards

I hadn’t ’til yesterday realised that EXIF metadata doesn’t actually store dates & times correctly.  Whoever came up with the spec all those decades ago clearly didn’t know how to work with dates & times correctly.  This is immensely frustrating since now we have countless images taken with timestamps that are collectively gibberish. The problem is… Read more

Swift’s String.write(toFile:…) can’t handle tildes

Result?  Explode: Error Domain=NSCocoaErrorDomain Code=4 “The folder “sigh.txt” doesn’t exist.” UserInfo={NSFilePath=~/Desktop/sigh.txt, NSUserStringVariant=Folder, NSUnderlyingError=0x1018110b0 {Error Domain=NSPOSIXErrorDomain Code=2 “No such file or directory”}} And since there’s no documentation on that write() method, and this is obviously a perfectly reasonable request that can’t sanely yield that bizarre error message, you could be forgiven for having no idea how… Read more

Nikon SnapBridge

Finally. Nikon have released the SnapBridge app so that the much-touted Bluetooth+Wifi capability of the D500 can actually be used.  A mere eight months after it was announced.  Fuck you too Nikon. However, as I’d clearly forgotten, it’s not very useful anyway.  It doesn’t work with raws, you see.  Doesn’t even acknowledge that they’re in the… Read more
