Can you “ignore” a file in Perforce?
... with an explanation of how it works. Then I noticed this answer, which is now superfluous I guess.
Assuming you have a client named "CLIENT", a directory named "foo" (located at your project root), and you wish to ignore all .dll files in that directory tree, you can add the following lines to y...

Why do I need to explicitly push a new branch?
...same name, creating them if they don't exist),
the default push policy is now 'simple' (push only the current branch, and only if it has a similarly named remote tracking branch on upstream, since git 1.7.11)
In both cases, since the upstream empty repo has no branch:
there is no matching named...
What are the barriers to understanding pointers and what can be done to overcome them? [closed]
...implified. There's more overhead and a lot more details you would

If the grouped fields are valid then it does not enter the submithandler and if invalid it enters invalidHandler but submits anyway! I'd say this is a fairly serio...
Simple explanation of MapReduce?
...rite it like this
A = [7, 8, 9]
sum = A.reduce( 0, (x, y) => x + y )
Now it's a little confusing why there are 2 arguments (0 and the function with x and y) passed. For a reduce function to be useful, it must be able to take 2 items, compute something and "reduce" that 2 items to just one sing...
Why functional languages? [closed]
