Understanding typedefs for function pointers in C
...d making typedefs of small chunks and using those small pieces as building blocks for larger and more complicated expressions. For example:
typedef int (*FUNC_TYPE_1)(void);
typedef double (*FUNC_TYPE_2)(void);
typedef FUNC_TYPE_1 (*FUNC_TYPE_3)(FUNC_TYPE_2);
rather than:
typedef int (*(*FUNC_T...
Using std Namespace
...t's completely under your control (and it can even be scoped to particular blocks if desired). I see no particlar reason to clutter up the code with a slew of std:: qualifiers - it just becomes a bunch of visual noise. However, if you're not using a whole bunch of names from the std namespace in y...
Comparison between Mockito vs JMockit - why is Mockito voted better than JMockit? [closed]
...nus, by calling
unverifiedInvocations() inside an
ordered verification block, you can
perform order-related verifications
that are simply impossible in Mockito.
Finally, the JMockit Testing Toolkit
has a wider scope and more ambitious
goals than other mocking toolkits, in

What are type lambdas in Scala and what are their benefits?
...call point or bind.
The type lambda trick exploits the fact that an empty block in a type position creates an anonymous structural type. We then use the # syntax to get a type member.
In some cases, you may need more sophisticated type lambdas that are a pain to write out inline. Here's an example...

What are copy elision and return value optimization?
...hose scope does not extend beyond the end of the innermost
enclosing try-block (if there is one), the copy/move operation from the operand to the exception
object (15.1) can be omitted by constructing the automatic object directly into the exception object

Shouldn't the conditional in the "actually" block read "if(pa is string && pb is string)"? I.e "&&" instead of "||" ?

What is the most robust way to force a UIView to redraw?
...on I've found is calling it manually after some time, to let anything that blocks the draw pass away, like this:
dispatch_time_t popTime = dispatch_time(DISPATCH_TIME_NOW,

dispatch_after(popTime, dispatch_get_main_queue(), ^...
commandButton/commandLink/ajax action/listener method not invoked or input value not set/updated
...Make sure that no Filter or Servlet in the same request-response chain has blocked the request fo the FacesServlet somehow. For example, login/security filters such as Spring Security. Particularly in ajax requests that would by default end up with no UI feedback at all. See also Spring Security 4 a...
