I do use Ninja when I use CMake, but honestly that mostly comes down to the fact that the Makefiles generated by CMake are horrifically slow. I don't particularly love CMake, I only use it because the C++ ecosystem really has nothing b

There does not need to be an additional cost for this. Most users will do this: 1. Check if there is a value 2. Get the value There is nothing theoretically preventing the compiler from enforcing that step 1 happens before step 2, especiall

This is a bad answer too, IMO. I think there is a solid case for the existence of undefined behavior; even Rust has it, it's nothing absurd in concept, and you do describe some reasoning for why it should probably exist. However, and h

Assertions are debug-only. Exceptions are usually not guaranteed to be available and much of the standard library doesn't require them. You could std::abort, and that's about it. I think the issue is that this just isn't part

The reason it works this way is there's legitimately no easy way around it. You're not guaranteed a reasonable zero value for any type, so you can't do the slightly better Go thing (defined behavior but still wrong... Not gre

I believe the latest versions of GCC, Clang, MSVC and XCode/AppleClang all support std::expected, in C++23 mode.

Google has been doing a very similar, but definitely somewhat uglier, thing with StatusOr<...> and Status (as seen in absl and protobuf) for quite some time. A long time ago, there was talk about a similar concept for C++ based on exc

You know, I thought UEFI actually was doing the same thing, but I am mistaken, at least for anything resembling modern UEFI. Apparently, modern UEFI just doesn't bother supporting classic Video BIOS option ROMs at all, only supporting

You can always ignore the BIOS routines and directly touch hardware registers/etc. so as long as you know precisely what hardware you are dealing with. Of course, this is what modern OSes do for most hardware after bootstrapping since

Sorry for your situation, or I suppose, glad to hear it's better. My understanding as a layperson is that antibiotics can be a nightmare for the gut: I don't think it's particularly likely, but you are a lot more likely to

For Norm, just the crude nature of a lot of his jokes felt like something that was very "American", at least certainly in the 90s and 2000s. His delivery, on the other hand, always felt fairly unique to me. It's also possible

Even as a U.S. citizen this hits me frequently. A lot of amazing comedians I didn't realize were Canadian for a long time, as a U.S. citizen. Norm Macdonald comes to mind, but he's far from alone.

As far as I know virtually all of the EFI vars will be stored on battery-backed NVRAM, so the usual solution is to just clear that, by removing the CMOS battery. I am pretty sure the only solution are things you definitely can not read or w

I'm more curious what your definition of harm is. (To be clear, this is a completely pointless tangent, "harm" has nothing to do with whether or not you should condone plagiarism. But you seem rather interested in discussing

Also worth noting: the version of GPL used by RTEMS seems to be one with a compiler exception, so it probably wouldn't have been an issue for HBC.

They just "froze" upstream development, but it was purely performative; there isn't actually active upstream development. If you wanted to fork it and continue development you certainly could.
