Is AngularJS just for single-page applications (SPAs)?
...s really, really easy to create a RESTful API with Express you can consume from your Angular application(s). Google NodeJS Express RESTful API and Angular's $resource and $http services. After that, just start prototyping and playing with it. I think you might find you're overthinking/worrying too m...
What exactly do “IB” and “UB” mean?
...r, implementations are required to specify a consistent behavior resulting from that action. Unfortunately, there is no category of behavior for which an implementation would be required to specify possible consequences, but would not be required to have any particular consequence occur consistentl...
Shell equality operators (=, ==, -eq)
...the right-hand-side must be quoted. If not quoted, it is a pattern match! (From bash man page: "Any part of the pattern may be quoted to force it to be matched as a string.").

$ rht="A*"
$ lft="A...

arrayfun can be significantly slower than an explicit loop in matlab. Why?
...which you can directly express as loop nests. Where does the overhead come from we can not know. Could the overhead be avoided by a better implementation? Maybe not. But unfortunately the only thing we can do is study the performance to identify the cases, in which it works well, and those, where it...
foldl versus foldr behavior with infinite lists
...rk backwards computing each application of f.
This is obviously a far cry from the efficient tail-recursion most functional programmers know and love!
In fact, even though foldl is technically tail-recursive, because the entire result expression is built before evaluating anything, foldl can cause...
How does std::move() transfer values into RValues?
...mple; named rvalue reference is treated as lvalue (and implicit conversion from lvalue to rvalue reference is forbidden by standard).
Here's what happens when we call move with lvalue:
Object a; // a is lvalue
Object b = std::move(a);
and corresponding move instantiation:
// move with [T = Ob...
