It will probably help you to know the three more common flags in git reset:
git reset [--<mode>] [<commit>]
This form resets the current branch head to <commit> and possibly
updates the index (resetting it to the tree of <...
What is a monad?
...p(x => [x + 1])
Here we supply an operation which returns an Array, so now it conforms to the pattern. The flatMap method executes the provided function for every element in the array. It expects an array as result for each invocation (rather than single values), but merges the resulting set of...
Change the Right Margin of a View Programmatically?
...eft, top, right, bottom
tv.setLayoutParams(params);
I can't test it right now, so my casting may be off by a bit, but the LayoutParams are what need to be modified to change the margin.

Declaring and initializing variables within Java switches

If you comment out the value = 2; assignment, the compiler still knows which variable you're referring to, but you won't have gone through any execution path which assigns it a value, which is why you get an error as you would when you try to read any other not-definitely-assigned local var...

...the result is greater than ten, subtracts ten. So f(2) = 5, f(8) = 1, etc. Now, we can make another function, call it f', that goes backwards, by adding seven instead of three. f'(5) = 2, f'(1) = 8, etc.
That's an example of a two-way function and its inverse. Theoretically, any mathematical functi...
