What does this square bracket and parenthesis bracket notation mean [first1,last1)?
...hics (color conversion, computational geometry, animation easing/blending, etc.) often times normalized numbers are used. That is, numbers between 0.0 and 1.0.
It is important to know the edge cases if the endpoints are inclusive or exclusive:
(0,1) = 1e-M .. 0.999...
(0,1] = 1e-M .. 1.0
[0,1) = ...
C++11 rvalues and move semantics confusion (return statement)
...move overloads for nearly anything (hash key and values, vector insertion, etc), and is where you will see them the most.
You can also use them to normal functions, and if you only provide an rvalue reference argument you can force the caller to create the object and let the function do the move. ...
Is JavaScript guaranteed to be single-threaded?
...etInterval, HTTP-request onload events (XHR), and UI events (click, focus, etc.) provide a crude impression of multi-threadedness - they are still all executed along a single timeline - one at a time - so even if we don't know their execution order beforehand, there's no need to worry about external...

Understanding checked vs unchecked exceptions in Java
... I dont have any code for that stuff, I just cooked up the names etc. If you see java.lang.Exception, it has 4 constructors two of them accept java.lang.Throwable. In snippets above I assumed LoginFailureException extends Exception and declares a constructor public LoginFailureException(Th...
Why should I prefer single 'await Task.WhenAll' over multiple awaits?
...will be lost. I.e. if t2 and t3 throws exception, only t2 will be catched; etc. The subsequent tasks exceptions will go unobserved.
Where as in the WhenAll - if any or all of the tasks fault, the resulting task will contain all of the exceptions. The await keyword still always re-throws the first ...
