Is it better to call ToList() or ToArray() in LINQ queries?
... (definitely in the minority).
EDIT
A couple of people have asked me about the consequence of having the extra unused memory in the List<T> value.
This is a valid concern. If the created collection is long lived, is never modified after being created and has a high chance of landing in...
Why are side-effects modeled as monads in Haskell?
... has side effects. If we take all the effects it produces as the input and output parameters, then the function is pure to the outside world.
So, for an impure function
f' :: Int -> Int
we add the RealWorld to the consideration
f :: Int -> RealWorld -> (Int, RealWorld)
-- input some states...
Differences between hard real-time, soft real-time, and firm real-time?
...e line is fuzzy, because even a pacemaker can be off by a small amount without killing the patient, but that's the general gist.
It's sort of like the difference between hot and warm. There's not a real divide, but you know it when you feel it.

You can print out all the created steps within the stack like this:
require('utils').dump(casper.steps.map(function(step) {
return step.toString();
}));
That gives:
$ casperjs test-steps.js
[
"function step1() { this.echo('this...
What are the rules for evaluation order in Java?
...termine in what order the subexpressions are evaluated. Your question is about the order in which subexpressions are evaluated.
Consider A() + B() + C() * D(). Multiplication is higher precedence than addition, and addition is left-associative, so this is equivalent to (A() + B()) + (C() * D()) B...
What's the difference between returning void and returning a Task?
...ght I'd just add a bit more context.
Your first question is essentially about what methods can be marked async.
A method marked as async can return void, Task or Task<T>. What are the differences between them?
A Task<T> returning async method can be awaited, and when the task comp...
How can I get a view's current width and height when using autolayout constraints?
I'm not talking about the frame property, because from that you can only get the view's size in the xib. I'm talking about when the view is resized because of its constraints (maybe after a rotation, or in response to an event). Is there a way to get its current width and height?

There's a super-handy visual semver calculator you can play with, making all of this much easier to grok and test.
