C++ Object Instantiation
...
Raw pointers are useful when you want auto_ptr-like semantics (transferring ownership), but retain the non-throwing swap operation, and don't want the overhead of reference counting. Edge case maybe, but useful.

Difference between an API and SDK
...include these API's plus all the goodies that developers need other than a raw API, hence the "kit". So you're right about building something vs. using/consuming(+/controlling/interacting), but the distinction is otherwise muddled.

Check if database exists in PostgreSQL using shell
...-f1 | grep -qxF "$DB_NAME"
The -t and -A options make sure the output is raw and not "tabular" or whitespace-padded output. Columns are separated by the pipe character |, so either the cut or the grep has to recognize this. The first column contains the database name.
EDIT: grep with -x to preven...
What is the difference between Swing and AWT?
...
Because Swing tries to do everything possible in Java other than the very raw graphics routines provided by a native GUI window, it used to incur quite a performance penalty compared to AWT. This made Swing unfortunately slow to catch on. However, this has shrunk dramatically over the last several ...
Which regular expression operator means 'Don't' match this character?

The former: don't match a, b, c or 0: [^a-c0]

(?!foo|bar).{3}
or
.{3}(?<!foo|bar)
Also, a correction...

Creating a new DOM element from an HTML string using built-in DOM methods or Prototype
...
Newer DOM implementations have range.createContextualFragment, which does what you want in a framework-independent way.
It's widely supported. To be sure though, check its compatibility down in the same MDN link, as it will be changing. As of May 2017 thi...
LINQ where vs takewhile
...
Where can examine the whole sequence looking for matches.
Enumerable.Range(1, 10).Where(x => x % 2 == 1)
// 1, 3, 5, 7, 9
TakeWhile stops looking when it encounters the first non-match.
Enumerable.Range(1, 10).TakeWhile(x => x % 2 == 1)
// 1
