Yes. And that would make sense. They might not insist on exactly this, but they already leave this sort of possibility open by suggesting that undefined behaviour could result in the program behaving "in a documented manner characteris

If ((uint32_t)x<<32)==x on one system, and ((uint32_t)x<<32)==0 on another, why is that a problem? The issue isn't that one system behaves differently from another. The issue is that compilers take it upon themselves to dec

The article suggests that new Macbook/OS X might be just as bad, but the linked twitter thread ( https://twitter.com/Catfish_Man/status/676851988596809728 ) makes the situation there sound rather less serious.

Yes, this has been my experience in the UK too (and probably everybody's). It may be a cultural difference but rows of local shops are not the preserve of gentrified areas. Anywhere people live, you will find these sorts of shops, beca

I restart every now and again just to make sure it still works, and that everything I expect to get loaded, gets loaded. Nothing worse than being obliged to do it for whatever reason and finding out the hard way (while you're in the mi

Another vote for ShiftIt here. I've been using it for a couple of years now, and I've found it fine for most purposes. Supports XQuartz+xquartzwm, supports multiple monitors, has configurable keyboard shortcuts. A few more options

I claim this is all highly unhelpful. Both the C and C++ standards explicitly permit an implementation to do something sensible in the face of undefined behaviour, the sort of thing that a regular user of the system in question might expect

Yes, good point. Sorry. This is not going to help the Z80 much in this particular comparison, is it :(

The basic operation for accessing a value from a structure is to take the address of the structure, add a compile-time constant offset to it, and use that address. There's an addressing mode specifically for this in the Z80: you put th

Hmm... in this case, you might be right. You'd then need to advance 2 registers by 8 each time, and you'd be paying an extra 3 T-states per compare for the fetch of the immediate operand, but you'd be saving 4+ cycles in vari

As a longtime 6502 programmer I was impressed by the Z80 after reading the data sheet - but actually trying to program it left me nonplussed. The main omissions as I recall were: lack of immediate addressing for the 16-bit arithmetic instru

cmake is pretty bad, too, though at least it runs on Windows. (And I don't think it's got quite the same goals as Autotools, though their scopes overlap in many respects.) I've never met anything build-related, scope large or

Preemption just means the task is stopped when its timeslice elapses, and a new task selected. You can do this on any CPU with a regular timer interrupt. On something like the ZX Spectrum you'll need to use the vblank interrupt; on som

I hope I get lucky with something like that one day! It's more usual that the front end thinks '+' is invalid too. The usual result is that my signup attempt is blocked. And when I send them feedback about it, I'm roundl

You'd have to be buying organic goat milk to pay that much. From the figures in the article: Buy it by the pint: 0.49 (British pounds per Imperial pint) = 4.90836249 U.S. dollars per US gallon Buy it by the 2 pints: (0.85 British pound

Perhaps somebody knows better than I do, but I'm pretty sure Unity only make the tools, which is a very different proposition! They will have the large files, but not the iteration. Storing large files somewhere outside the working cop
