git discard all changes and pull from upstream
...you can reset --hard to the common ancestor and then do a pull, which will fast-forward to the latest commit on the remote master.
To be concrete, here's a simple extension of Nevik Rehnel's original answer:
git reset --hard origin/master
git pull origin master
NOTE: using git reset --hard will ...
Why are `private val` and `private final val` different?
... if they want an inlined constant, a value that should never change but is fast, they write "final val". if they want flexibility to change the value without breaking binary compatibility, just "val".

... never thought of. As others have mentioned, using tags is a fantastic and fast way to zoom around your source code and using M-/ (dabbrev-expand) often does exactly what you expect when completing a variable name.

Can Python test the membership of multiple values in a list?

True
Speed Tests
In many cases, the subset test will be faster than all, but the difference isn't shocking -- except when the question is irrelevant because sets aren't an option. Converting lists to sets just for the purpose of a test like this won't always be worth the trouble. ...

Collection versus List what should you use on your interfaces?
...t designed to be easily extensible by subclassing it; it is designed to be fast for internal implementations. You'll notice the methods on it are not virtual and so cannot be overridden, and there are no hooks into its Add/Insert/Remove operations.
This means that if you need to alter the behavior...
Is there a standard sign function (signum, sgn) in C/C++?

Fast! copysign is slow, especially if you need to promote and then narrow again. This is branchless and optimizes excellently
Standards-compliant! The bitshift hack is neat, but only works for some bit representations, and do...
