Best way to represent a fraction in Java?
..., use 18 digits so that the number
//will be at least as accurate as a cast to a double. For example, with
//the fraction 1/3, precision will be 1, giving a result of 0.3. This is
//quite a bit different from what a user would expect.
if(precision < 18)
precision = 18;

How to determine CPU and memory consumption from inside a process?
...
@CinCout you need a casting.. replace GetProcessMemoryInfo(GetCurrentProcess(), &pmc, sizeof(pmc)); with GetProcessMemoryInfo(GetCurrentProcess(), (PROCESS_MEMORY_COUNTERS*)&pmc, sizeof(pmc));

C++ performance vs. Java/C#
...se method (from string to T), or an efficient equivalent of boost::lexical_cast in C# to understand the problem)
RAII remains unmatched (GC still can leak (yes, I had to handle that problem) and will only handle memory. Even C#'s using is not as easy and powerful because writing a correct Dispose im...
Where and why do I have to put the “template” and “typename” keywords?
... (e.g: a non-type template parameter N)
Type-dependent expressions (e.g: a cast to a type template parameter (T)0)
Most of the rules are intuitive and are built up recursively: For example, a type constructed as T[N] is a dependent type if N is a value-dependent expression or T is a dependent type...

What are Aggregates and PODs and how/why are they special?
..., if a POD-class A's first member is of type T, you can safely reinterpret_cast from A* to T* and get the pointer to the first member and vice versa.
The list goes on and on…
Conclusion
It is important to understand what exactly a POD is because many language features, as you see, behave diffe...
