Is it intended by the C++ standards committee that in C++11 unordered_map destroys what it inserts?
...ehaviour, you observe, which always moves, is a bug in libstdc++, which is now fixed according to a comment on the question. For those curious, I took a look at the g++-4.8 headers.

Javascript when to use prototypes
...ultiple Car() instances.
var volvo = new Car(),
saab = new Car();
Now, you know each car will need to drive, turn on, etc. Instead of attaching a method directly to the Car() class (which takes up memory per each instance created), you can attach the methods to the prototype instead (creat...
What is the meaning of single and double underscore before an object name?
...but rather the ("organizing") public methods such as put and get (this is known as the Template Method design pattern -- see e.g. here for an interesting presentation based on a video of a talk of mine on the subject, with the addition of synopses of the transcript).
Edit: The video links in the de...
How to fix: “UnicodeDecodeError: 'ascii' codec can't decode byte”
...ython 2.x - The Long Version
Without seeing the source it's difficult to know the root cause, so I'll have to speak generally.
UnicodeDecodeError: 'ascii' codec can't decode byte generally happens when you try to convert a Python 2.x str that contains non-ASCII to a Unicode string without specifyi...
Python extending with - using super() Python 3 vs Python 2
...o by doing nothing in C, you end up calling both, which is what you want.
Now if you were not using super, you would end up inheriting A.__init__ (as before) but this time there's nothing that would call B.__init__ for you.
class A:
def __init__(self):
print('A')
class B:

Does const mean thread-safe in C++11?
...ration --at least not in respect to data races--.
Does that mean const is now the equivalent of Java's synchronized?
No. Not at all...
Consider the following overly simplified class representing a rectangle:

Why declare unicode by string in python?
...nsparently by the interpreter; the most obvious difference is that you can now embed unicode characters in the string (that is, u'\u2665' is now legal). You can use from __future__ import unicode_literals to make it the default.
This only applies to Python 2; in Python 3 the default is Unicode, an...
How to securely store access token and secret in Android?
...instead of the actual username password:
Third party apps don't need to know the password and the user can be sure that they only send it to the original site (Facebook, Twitter, Gmail, etc.)
Even if someone steals a token, they don't get to see the password (which the user might be using on other...
Is there a way to cause git-reflog to show a date alongside each entry?
... The problem with this is that %gd doesn't show the same date as @{now} does. When searching the reflog, knowing the exact time can be really important ("I know it was in the right state at 8:57" for example).
