Add st, nd, rd and th (ordinal) suffix to a number
... 11, 12 or 13 use -th (e.g. 11th, pronounced eleventh, 112th,

The following JavaScript code (rewritten in Jun '14) accomplishes this:
function ordinal_suffix_of(i) {
var j = i % 10,

What's the difference between the 'ref' and 'out' keywords?
...ual reference to someobject gets sent to the method. So you now have only one reference to the data:
(outside method) reference1 => someobject;
(inside method) reference1 => someobject;
But what does this mean? It acts exactly the same as sending someobject not by ref except for two main...
Python loop that also accesses previous and next values
...
This should do the trick.
foo = somevalue
previous = next_ = None
l = len(objects)
for index, obj in enumerate(objects):
if obj == foo:
if index > 0:
previous = objects[index - 1]
if index < (l - 1):
next_ = objects[index + 1]
Here's t...

Java NIO FileChannel versus FileOutputstream performance / usefulness
...as been that this buffer size is ripe for tuning. I've settled on 4KB for one part of my application, 256KB for another. I suspect your code is suffering with such a large buffer. Run some benchmarks with buffers of 1KB, 2KB, 4KB, 8KB, 16KB, 32KB and 64KB to prove it to yourself.

@WarFox I don't think anyone has made an official recommendation. IME, the formats which come from w3c for interoperability tend to be in the hyphen style; formats which come from Microsoft and some others tend to be tightly coupled to an implementat...
LINQ Aggregate algorithm explained

Is there a bash command which counts files?
...
This simple one-liner should work in any shell, not just bash:
ls -1q log* | wc -l
ls -1q will give you one line per file, even if they contain whitespace or special characters such as newlines.
The output is piped to wc -l, which co...

This is how / why the algorithm works.
Suppose that the N numbers in the list are not distinct, or that one or more of them is greater than N. This means that there must be at least one number in the ra...

@JonathanMDavis: Arrays are not pointers. And for everyone: For the sake of ending this ever-prominent confusion, stop referring to (some) pointers as "decayed arrays". There's no such terminology in the language, and there really isn't a use for it. Pointers are pointers, arrays...
