..."RPC-by-concrete-type" while RequestFactory is "RPC-by-interface".
RPC is more convenient to get started with, because you write fewer lines of code and use the same class on both the client and the server. You might create a Person class with a bunch of getters and setters and maybe some simple b...
Synchronization vs Lock
...nchronized(myObject) {
doSomethingNifty();
}
That said, Locks may be more useful for more complicated things where you can't acquire and release in such a clean manner. I would honestly prefer to avoid using bare Locks in the first place, and just go with a more sophisticated concurrency cont...

However, this use case is very rare. You rarely need to pass around unnamed function objects.
The builtins map() a...
How are 3D games so efficient? [closed]
... since you can't see it, there's no need to try to show it to you.
Furthermore, optimized instructions and special techniques exist when you're developing against a particular set of hardware, to enable even better speedups.
The other part of your question is why a demo uses so much CPU:

Need for predictable random generator
...the time, 0 critical hits were scored in 10 tries. 3.3% of the time, 5 or more critical hits were landed out of 10. Naturally, using this algorithm (with a minimum roll count of 5), a much smaller amount (0.03%) of the "Fairish" runs were out of bounds. Even if the below implementation is unsuita...
Should I use JSLint or JSHint JavaScript validation? [closed]
...hile JSHint has changed a great deal - it has thrown away many of JSLint's more antagonistic rules, has added a whole load of new rules, and has generally become more flexible. Also, another tool ESLint is now available, which is even more flexible and has more rule options.

Like I said, you aren't going to create any more total throughput for said ride, but there may be rides being underutilized elsewhere. If you are now able to ride these rides as well as the rides you have to wait on, then you can increase the overall efficiency of the ...
Difference between scaling horizontally and vertically for databases [closed]
...
Horizontal scaling means that you scale by adding more machines into your pool of resources whereas Vertical scaling means that you scale by adding more power (CPU, RAM) to an existing machine.
An easy way to remember this is to think of a machine on a server rack, we add mo...
