Which kind of pointer do I use when?
Ok, so the last time I wrote C++ for a living, std::auto_ptr was all the std lib had available, and boost::shared_ptr was all the rage. I never really looked into the other smart pointer types boost provided. I understand that C++11 now provides some of the types boost came up with, but not all ...
Best explanation for languages without null
...all people have one).
FWIW, without first invoking undefined behaviour, C++ references cannot "point to" null, and it's not possible to construct a class with uninitialized reference member variables (if an exception is thrown, construction fails).
Sidenote: Occasionally you might want mutually-...
Lock-free multi-threading is for real threading experts
...pattern (I'm not as familiar with what's available in native-compiled C or C++ and it's harder there due to no garbage collection). Perhaps you and I have a different definition of spinning: I don't consider the "CAS-retry" you find in lock-free stuff "spinning". IMO "spinning" implies hot-waiting.

When is assembly faster than C?
...n heavy fixed point code by writing a couple of asm-lines.
Using Visual C++ 2013 gives the same assembly code for both ways.
gcc4.1 from 2007 also optimizes the pure C version nicely. (The Godbolt compiler explorer doesn't have any earlier versions of gcc installed, but presumably even older GC...
Do zombies exist … in .NET?
...ie threads with .NET code. I probably could have figured out that calling C++ code that's known to cause that issue from .NET code would produce the desired effect. You obviously know a lot about this stuff. Do you know of any other cases (possibly weird, but not weird enough to never happen unin...
