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...

Why doesn't Java support unsigned ints?
...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...
Performance of Java matrix math libraries? [closed]
...with itself. The results are as follows.
Using multithreaded ATLAS with C/C++, Octave, Python and R, the time taken was around 4 seconds.
Using Jama with Java, the time taken was 50 seconds.
Using Colt and Parallel Colt with Java, the time taken was 150 seconds!
Using JBLAS with Java, the time t...
Const before or const after?
...hink putting it on the right makes more sense. You generally read types in C++ from right-to-left, for example Object const * is a pointer to a const Object. If you put the const on the left, it would read as a pointer to an Object that is const, which doesn't really flow very well.
