Apple “Feedback” #12149675. Some netmasks returned by getifaddrs have family of AF_INET yet a length less than sizeof(sockaddr_in), e.g. 5, 6, 7, or 8. On macOS Ventura 13.3.1, at least. It looks like it’s actually allocating only eight bytes for the ifa_netmask (not the 16 that is the size of sockaddr_in per MacOSX13.3.sdk/usr/include/netinet/in.h), as it… Read more
This is in the context of coming from a D500 (and a number of DX DSLRs prior to that), and is based only on the first hour or so of using it.
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
I’d forgotten about this until I stumbled across a reference to it again recently. This was a little hack I worked on back in 2004, with Mac OS X Tiger (10.4). Yes, kids, macOS was called Mac OS X back in ye Olden Times. Wow, Slashdot looked even uglier than I remember, back then. Though… Read more
swift/lib/Basic/LangOptions.cpp has most of the conditional compilation macros (called “Language Options” in the compiler internally). Notably the swift() version macro is absent, and doesn’t seem to be defined anywhere… At time of writing the two undocumented additions, to the os(), arch(), and swift() set, are _endian() and _runtime(). I have no idea if they’re useful… Read more
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
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
