What does $NON-NLS-1$ mean?
...e hard-coded strings not part of the internationalization:
public String foo(String key) {
return "!" + key + "!"; //$NON-NLS-1$ //$NON-NLS-2$

Passing a std::array of unknown size to a function

I've looked into this and it appears that auto foo(auto bar) { return bar * 2; } is not currently valid C++ even though it compiles in GCC7 with the C++17 flag set. From reading here, function parameters declared as auto are part of the Concepts TS which should eventually...

When to use references vs. pointers
...ou only have access to (poorly documentated) headers, and signatures like
foo(int* const a, int b);
are not easy to interpret at first sight.
Imho, references are as good as pointers when no (re)allocation nor rebinding (in the sense explained before) is needed. Moreover, if a developer only use...
Injecting $state (ui-router) into $http interceptor causes circular dependency
..., do
this.$rootScope.$emit("unauthorized");
plus
angular
.module('foo')
.run(function($rootScope, $state) {
$rootScope.$on('unauthorized', () => {
$state.transitionTo('login');
});
});
That way you have separated the concerns:
