Virtual member call in a constructor
...
The rules of C# are very different from that of Java and C++.
When you are in the constructor for some object in C#, that object exists in a fully initialized (just not "constructed") form, as its fully derived type.

namespaces for enum types - best practices
...
Original C++03 answer:
The benefit from a namespace (over a class) is that you can use using declarations when you want.
The problem with using a namespace is that namespaces can be expanded elsewhere in the code. In a large projec...
count vs length vs size in a collection
...to the number of elements in the vector, not its capacity()… at least in C++, which I think is the originator of vectors with sizes.

Is Python interpreted, or compiled, or both?
...terpreters and projects that attempt to compile a subset of Python to C or C++ code (and subsequently to machine code).
Second, compilation is not restricted to ahead-of-time compilation to native machine code. A compiler is, more generally, a program that converts a program in one programming lang...
Using GCC to produce readable assembly?
...nking relocations / symbol names (useful on shared libraries)
-C demangles C++ symbol names
-w is "wide" mode: it doesn't line-wrap the machine-code bytes
-Mintel: use GAS/binutils MASM-like .intel_syntax noprefix syntax instead of AT&T
-S: interleave source lines with disassembly.
You could p...

...ses, they felt that the most common need was for signed data types". In my C++ code, I more than often find myself thinking "Why on earth am I using a signed integer here instead of an unsigned one?!". I have the feeling that "signed" is the exception rather than the rule (of course, it depends on t...
What is the python “with” statement designed for?
...The with statement can thus be used in ways similar to the RAII pattern in C++: some resource is acquired by the with statement and released when you leave the with context.
Some examples are: opening files using with open(filename) as fp:, acquiring locks using with lock: (where lock is an instance...

Has anyone actually implemented a Fibonacci-Heap efficiently?

The Boost C++ libraries include an implementation of Fibonacci heaps in boost/pending/fibonacci_heap.hpp. This file has apparently been in pending/ for years and by my projections will never be accepted. Also, there have been bugs in...
