'size_t' vs 'container::size_type'
...ct type, so for example one knows where the type wraps around to (like, to UINT_MAX) so that one can make use of that. Or for templates, where you really need to pass two identical types to function/class templates.
Often i find i use size_t for brevity or iterators anyway. In generic code, since y...

Python List vs. Array - when to use?
...even for data that could be represented with simple C types (e.g. float or uint64_t).
The array.array type, on the other hand, is just a thin wrapper on C arrays. It can hold only homogeneous data (that is to say, all of the same type) and so it uses only sizeof(one object) * length bytes of memory...
Equivalent of typedef in C#
...
I couldn't convert typedef uint8 myuuid[16]; through "using" directive. using myuuid = Byte[16]; doesn't compile. using can be used just for creating type aliases. typedef seems to be much more flexible, since it can create an alias for a whole declara...

As it turns out, Buffer instances represent/interpret strings encoded in UTF-8 by default. By contrast, in desktop Chrome, you can't even input a string that contains characters outsi...
