How to use Git?
... your questions directly rather than pointing you at documentation:
1) In order to keep it up to date, do a git pull and that will pull down the latest changes in the repository, on the branch that you're currently using (which is generally master)
2) I don't think there's something (widely availa...

Eclipse menus don't show up after upgrading to Ubuntu 13.10
... that the fact that it is installed there forces me to run sudo eclipse in order to get the menus, or else it doesn't work. However, when I just copy-pasted your file content without modifying it, the menus work without sudo priviliges, even though I of course have no directory name /home/USERNAME.....
How do API Keys and Secret Keys work? Would it be secure if I have to pass my API and secret keys to
..., if 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 f...
How is the fork/join framework better than a thread pool?
...ypical FJ usage cuts the problem into tiny pieces. Doing these in a random order requires much co-ordination at a hardware level. The overheads would be a killer. In FJ, tasks are put onto a queue that the thread reads off in Last In First Out order (LIFO/stack), and work stealing (in core work, gen...

...POST /comments
post :create, :comment => {:article_id=>42, ...}
In order to test the route that they may prefer, they need to do it this way:

Floating point vs integer calculations on modern hardware
...
This "benchmark" has no data parallelism for out-of-order execution, because every operation is done with the same accumulator (v). On recent Intel designs, divide isn't pipelined at all (divss/divps has 10-14 cycle latency, and the same reciprocal throughput). mulss however...
Convert Array to Object
...completeness, reduceRight allows you to iterate over your array in reverse order:
[{ a: 1},{ b: 2},{ c: 3}].reduceRight(/* same implementation as above */)
will produce: {c:3, b:2, a:1}
Your accumulator can be of any type for you specific purpose. For example in order to swap the key and value o...
Move assignment operator and `if (this != &rhs)`
... function, and utilize a mix of rvalue references and lvalue references in order to "prevent" extra temporaries from being created during some stacked addition operation on the object-type:
struct A; //defines operator=(A&& rhs) where it will "steal" the pointers
