Why does Unicorn need to be deployed together with Nginx?
...ing Unicorn without a reverse proxy. However, that wouldn't be a very good idea; let's see why.
Unicorn follows the Unix philosophy which is to do one thing and do it well, and that is to serve fast, low-latency clients (we'll see what this means later on). The fact that Unicorn is designed for fas...
What is difference between Collection.stream().forEach() and Collection.forEach()?
...ration order of the Iterable, if one is specified.
Another issue is with side effects. The action specified in Stream.forEach is required to be non-interfering. (See the java.util.stream package doc.) Iterable.forEach potentially has fewer restrictions. For the collections in java.util, Iterable.fo...

What is the difference between LR, SLR, and LALR parsers?
...rrent state S (and associated lookahead, GOTO, and reduction tables) to decide what to do:
SHIFT: If the current table says to SHIFT on the token T, the pair (S,T) is pushed onto the parse stack, the state is changed according to what the GOTO table says for the current token (e.g, GOTO(T)), anoth...

Is gcc std::unordered_map implementation slow? If so - why?
...correctly, unordered_map defaults to (smallest prime larger than) 100.
I didn't have chrono on my system, so I timed with times().
template <typename TEST>
void time_test (TEST t, const char *m) {
struct tms start;
struct tms finish;
long ticks_per_second;
times(&start);...
What are copy elision and return value optimization?
...n practice (restrictions apply).
It's the only form of optimization that elides (ha!) the as-if rule - copy elision can be applied even if copying/moving the object has side-effects.
The following example taken from Wikipedia:
struct C {
C() {}
C(const C&) { std::cout << "A copy was ma...
Why can't I initialize non-const static member or static array in class?
...ws only static constant integral or enumeration types to be initialized inside the class. This is the reason a is allowed to be initialized while others are not.

If a static data member is of const integral or const enumeration type, its declaratio...

There are numerous questions here. Considering them one at a time:

Reference assignment is atomic. Interlocked.Exchange does not do only reference assignment. It does a...
