Why Choose Struct Over Class?
... threads racing to access/modify a single instance of a variable. (For the more technically minded, the exception to that is when capturing a struct inside a closure because then it is actually capturing a reference to the instance unless you explicitly mark it to be copied).
Classes can also becom...

So you can set cache to true in its options:
$http.get(url, { cache: true}).success(...);

Why do people say there is modulo bias when using a random number generator?
...e, and so you'll need to perform RAND_MAX/n calls to rand() on average.
A more efficient formula approach would be to take some large range with a length divisible by n, like RAND_MAX - RAND_MAX % n, keep generating random numbers until you get one that lies in the range, and then take the modulus:...
Returning multiple values from a C++ function
...u should look at boost::tuple (in C++11 and newer, there's std::tuple) for more than two return results.
With introduction of structured binding in C++ 17, returning std::tuple should probably become accepted standard.

Sometimes you have a member variable that should never be nil, but it cannot be set to the correc...
Should you always favor xrange() over range()?
...on or even just normal indexing, xrange() will work fine (and usually much more efficiently). There is a point where range() is a bit faster than xrange() for very small lists, but depending on your hardware and various other details, the break-even can be at a result of length 1 or 2; not something...
What are the rules for evaluation order in Java?
...e different. Coming up with an actual rule that covers all cases is rather more difficult. The designers of C# and Java chose a simple, easy-to-explain rule: "go left-to-right". What is your proposed replacement for it, and why do you believe your rule is better?
