...:file$ ]] && sourced=1 || sourced=0
$ZSH_EVAL_CONTEXT contains information about the evaluation context - call this outside of a function. Inside a sourced script['s top-level scope], $ZSH_EVAL_CONTEXT ends with :file.
Caveat: Inside a command substitution, zsh appends :cmdsubst, so test ...
Determining complexity for recursive functions (Big O notation)
... to find T(n-1) as follow: T(n-1) = T(n-1-1) + 1. It looks like we can now form a function that can give us some sort of repetition so we can fully understand. We will place the right side of T(n-1) = ... instead of T(n-1) inside the method T(n) = ... which will give us: T(n) = T(n-1-1) + 1 + 1 whic...
What's the $unwind operator in MongoDB?
...ts, joins, etc. from your mind. The way that it stores your data is in the form of documents and collections, which allows for a dynamic means of adding and obtaining the data from your storage locations.

How come a non-const reference cannot bind to a temporary object?
...signment to 'x'.
Note that getx() does not return a reference but a fully formed object into the local context. The object is temporary but it is not const, thus allowing you to call other methods to compute a value or have other side effects happen.
// It would allow things like this.

Could someone explain the pros of deleting (or keeping) unused code?
... is a very specific case: when the code is written in a weird/un-intuitive form and the clean way of re-writing it doesn't work for a really subtle reason. This should also be applied only after a repeated attempt has been made to correct the issue and every time the attempt has re-introduced the sa...
What does `someObject.new` do in Java?
...Java in version 1.1 of the language they were originally defined as a transformation to 1.0 compatible code. If you look at an example of this transformation, I think it will make it a lot clearer how an inner class actually works.
Consider the code from Ian Roberts' answer:

What is The Rule of Three?
...hows two distinct copying scenarios.
The initialization person b(a); is performed by the copy constructor.
Its job is to construct a fresh object based on the state of an existing object.
The assignment b = a is performed by the copy assignment operator.
Its job is generally a little more complicate...
