Is “argv[0] = name-of-executable” an accepted standard or just a common convention?
...e_t getExecutablePathName(char* pathName, size_t pathNameCapacity)
{
uint32_t pathNameSize = 0;
_NSGetExecutablePath(NULL, &pathNameSize);
if (pathNameSize > pathNameCapacity)
pathNameSize = pathNameCapacity;
if (!_NSGetExecutablePath(pathName, &pathNameSize))

Reading 64bit Registry from a 32bit application
...t.Unicode, SetLastError = true)]
public static extern int RegGetValue(
UIntPtr hkey, string lpSubKey, string lpValue, RegistryFlags dwFlags,
out RegistryType pdwType, IntPtr pvData, ref uint pcbData);
Use it like:
IntPtr data = IntPtr.Zero;
RegistryType type;
uint len = 0;

How do I check if a type is a subtype OR the type of an object?
...gnableFrom(typeof(Base)).Dump();
typeof(int[]).IsAssignableFrom(typeof(uint[])).Dump();
}
public class Base { }
public class Derived : Base { }
Here you get the following output:
True
True
True
The last True there would indicate, if the method only answered the question asked, that uint[] ...
(How) can I count the items in an enum?

Determining 32 vs 64 bit in C++
... This led me to the correct answer, but I think you should compare to UINT64_MAX not INT64_MAX. I used SIZE_MAX == UINT64_MAX -- prob the same

What are the rules about using an underscore in a C++ identifier?
...the "_t" issue: n1256 (C99 TC3) says: "Typedef names beginning with int or uint and ending with _t" are reserved. I think that still allows using names like "foo_t" - but i think these are then reserved by POSIX.

What platforms have something other than 8-bit char?

TI C62xx and C64xx DSPs also have 16-bit chars. (uint8_t isn't defined on that platform.)

What's the meaning of interface{}?
... b makes a copy of b rather than point at b for the same reason that var c uint64 = b makes a copy: if b later changes, s and c are supposed to have the original value, not the new one.
Values stored in interfaces might be arbitrarily large, but only one word is dedicated to holding the value in t...
