What is 'Currying'?
I've seen references to curried functions in several articles and blogs but I can't find a good explanation (or at least one that makes sense!)

Static/Dynamic vs Strong/Weak
...implemented in the high-level language. For example, Objective Caml has a function called Obj.magic which has the run-time effect of simply returning its argument, but at compile time it converts a value of any type to one of any other type. My favorite example is Modula-3, whose designers called ...
What are the rules for the “…” token in the context of variadic templates?
...comma ,.
It can be best understood by some examples. Suppose you have this function template:
template<typename ...T> //pack
void f(T ... args) //pack
{
// here are unpack patterns
g( args... ); //pattern = args
h( x(args)... ); //pattern = x(args)
m( y(args...) );...
How to test that no exception is thrown?
...
You're approaching this the wrong way. Just test your functionality: if an exception is thrown the test will automatically fail. If no exception is thrown, your tests will all turn up green.
I have noticed this question garners interest from time to time so I'll expand a little...
What are JavaScript's builtin strings?
...I would like to thank Jason and all the contributors for playing with that funny snippet. I have written that piece of code just for fun in order to send it to my wife on February 14 :) Having only Chrome installed on the laptop I had no options to check how it works in Firefox and IE. Moreover, I h...

# First argument is a function name that takes two arguments and compares them

surface plots in matplotlib
...n in 2d arrays.
If all you have is a list of 3d points, rather than some function f(x, y) -> z, then you will have a problem because there are multiple ways to triangulate that 3d point cloud into a surface.
Here's a smooth surface example:
import numpy as np

Why not use java.util.logging?

If for whatever reason you hate the SLF4J API and using it will snuff the fun out of your work, then by all means go for j.u.l. After all, there are means to redirect j.u.l to SLF4J.
By the way, j.u.l parametrization is at least 10 times slower than SLF4J's which ends up making a noticeable differ...
