Why does git perform fast-forward merges by default?
...
Fast-forward merging makes sense for short-lived branches, but in a more complex history, non-fast-forward merging may make the history easier to understand, and make it easier to revert a group of commits.
Warning: Non-fast-forwarding has potential side effects as well. Please review https:...
Print a list in reverse order with range()?
...
use reversed() function:
reversed(range(10))
It's much more meaningful.
Update:
If you want it to be a list (as btk pointed out):

How best to determine if an argument is not sent to the JavaScript function
...bits the 'most correct' behaviour, but it might not be feasible if there's more than one optional argument.
The test for undefined is next 'best' - it only 'fails' if the function is explicitly called with an undefined value, which in all likelyhood should be treated the same way as omitting the ar...
Detecting superfluous #includes in C/C++?

AngularJS Folder Structure [closed]
.... Not too bad for smaller apps, but even here you can start to see it gets more difficult to find what you are looking for. When I want to find a specific view and its controller, they are in different folders. It can be good to start here if you are not sure how else to organize the code as it is q...
