What is the most effective way for float and double comparison?
...the order of operations can produce different results, it is important to know how "equal" you want the numbers to be.
Comparing floating point numbers by Bruce Dawson is a good place to start when looking at floating point comparison.
The following definitions are from The art of computer progr...
What's the difference between design patterns and architectural patterns?
...tailed explanation but I will try to sketch the differences to best of my knowledge.
Patterns are distilled commonality that you find in programs. It allows us to deconstruct a large complex structure and build using simple parts. It provides a general solution for a class of problems.
A large co...
Why isn't String.Empty a constant?
...tring.Empty read only instead of a constant? I'm just wondering if anyone knows what the reasoning was behind that decision.

Undefined, unspecified and implementation-defined behavior
...clude <iostream>
int main()
{
char* p = "hello!\n"; // yes I know, deprecated conversion
p[0] = 'y';
p[5] = 'w';
std::cout << p;

Flags to enable thorough and verbose g++ warnings
...re present:
I include -Wno-unused because I often have variables that I know I
will use later, but do not yet have the functionality written for.
Removing warnings about that allows me to write in my preferred style
of occasionally deferring the implementation of things. It is useful
to turn that ...
Compiled vs. Interpreted Languages
...ler (gcj) and an interpeter for a superset of Java (bsh). So what is Java now? Bytecode-compiled, native-compiled or interpreted?
Other languages, which are compiled as well as interpreted, are Scala, Haskell or Ocaml. Each of these languages has an interactive interpreter, as well as a compile...
Useless use of cat?
...single greps you learn the placement of the file argument and it is ready knowledge that the first is the pattern and the later ones are file names.
It was a conscious choice to use cat when I answered the question, partly because of a reason of "good taste" (in the words of Linus Torvalds) but chi...
How do I choose grid and block dimensions for CUDA kernels?
...rion to choose the block size, it would be worth mentioning that CUDA 6.5 (now in Release Candidate version) includes several new runtime functions to aid in occupancy calculations and launch configuration, see
CUDA Pro Tip: Occupancy API Simplifies Launch Configuration
One of the useful functions...
Are HLists nothing more than a convoluted way of writing tuples?
...tions for HLists is abstracting over arity. Arity is typically statically known at any given use site of an abstraction, but varies from site to site. Take this, from shapeless's examples,
def flatten[T <: Product, L <: HList](t : T)
(implicit hl : HListerAux[T, L], flatten : Flatten[L]) : ...
