Find the min/max element of an Array in JavaScript
...big arrays (~10⁷ elements), Math.min and Math.max both produces the following error in Node.js.
RangeError: Maximum call stack size exceeded
A more robust solution is to not add every element to the call stack, but to instead pass an array:
function arrayMin(arr) {
return arr.reduce(func...
Get value from JToken that may not exist (best practices)
...e sake of moving my code to a platform that has a better JSON parser (say, Win8 for example). So, for what I asked, yes, your code would be perfect.

Multiprocessing: How to use Pool.map on a function defined in a class?
...rictions on what sort of functions pool.map could accept. I wrote the following to circumvent this. It appears to work, even for recursive use of parmap.
from multiprocessing import Process, Pipe

def spawn(f):
def fun(pipe, x):
pipe.send(f(x))

How do I “source” something in my .vimrc file?
...:set yy bbbb4dw
The only file sourced by default is the .vimrc(_vimrc on windows) so that's a place you can keep all the commands you use to set up Vim every time.
Where it gets interesting is the fact that since a sourced file is just a series of commands, and sourcing is a command, you can sour...

This immediate-constant bitmap is a big win, because there's no cache miss on the bitmap. It works if the "special" error codes are all in a range 64 or less. (or 32 for legacy 32bit code.) The compiler subtracts the smallest case value, if it's non-zero. The t...

Advantages of std::for_each over for loop
..., replace, etc and these won't look so strange anymore. This can be a huge win.
Update 1:
Most importantly, it helps you go beyond for_each vs. for-loops like that's all there is, and look at the other STL-alogs, like find / sort / partition / copy_replace_if, parallel execution .. or whatever.

Hashset vs Treeset

.NET - Dictionary locking vs. ConcurrentDictionary
... Or, what if two customers reaches for the same item at the same time, who wins? Will there be a fight? This is a non-threadsafe-collection. There's plenty of ways to avoid problems, but they all require some kind of locking, or rather explicit access in some way or another.
On the other hand, cons...
