What is the JSF resource library for and how should it be used?
...module/theme name where all of those resources commonly belong to.
Easier identifying
This way it's so much easier to specify and distinguish where those resources belong to and/or are coming from. Imagine that you happen to have a primefaces.css resource in your own webapp wherein you're overridi...
Websocket API to replace REST API?
...r more than just realtime features is very appealing.
I am seriously considering moving my app from a RESTful architecture to more of an RPC style via websockets. This is not a "toy app", and I'm not talking about only realtime features, so I do have reservations. But I see many benefits in going ...

@Ashwin: "You said runOnUiThread() executes the Runnable immediately" -- no, I did not. Please re-read the comment. I said "runOnUiThread() checks the current thread and executes the Runnable immediately if we happen to be on the main applic...
Difference between a “coroutine” and a “thread”?
...cedures AKA functions -- they just pass the baton among each other more fluidly).
Threads are (at least conceptually) a form of concurrent processing: multiple threads may be executing at any given time. (Traditionally, on single-CPU, single-core machines, that concurrency was simulated with som...
Blocks on Swift (animateWithDuration:animations:completion:)
...lf.blurBg.alpha = 1
}, completion: {
(value: Bool) in
self.blurBg.hidden = true
})
The important part here is the (value: Bool) in. That tells the compiler that this closure takes a Bool labeled 'value' and returns void.
For reference, if you wanted to write a closure that returned a bool...
How is Perl's @INC constructed? (aka What are all the ways of affecting where Perl modules are searc
...ote: Since @INC is used during the compilation phase, this must be done inside of a BEGIN {} block, which precedes the use MyModule statement.
Add directories to the beginning via unshift @INC, $dir.
Add directories to the end via push @INC, $dir.

C++ auto keyword. Why is it magic?
...learn C++, auto has always been a weird storage duration specifier that didn't serve any purpose. But just recently, I encountered code that used it as a type name in and of itself. Out of curiosity I tried it, and it assumes the type of whatever I happen to assign to it!

Why would iterating over a List be faster than indexing through it?
...complexity is effectively O(N^2) just to traverse the list!
If instead I did this:
for(String s: list) {
System.out.println(s);
}
then what happens is this:
head -> print head -> item1 -> print item1 -> item2 -> print item2 etc.
all in a single traversal, which is O(N).
No...
