Why is the use of alloca() not considered good practice?
...
@ninjalj: Not by highly experienced C/C++ programmers, but I do think many people who fear alloca() do not have the same fear of local arrays or recursion (in fact many people who will shout down alloca() will praise recursion because it "looks elegant"). I agre...
Which would be better for concurrent tasks on node.js? Fibers? Web-workers? or Threads?
...perior.

...e Enumerable.Repeat() in the following way (implemented Pair just like the C++ equivalent): Enumerable.Repeat( new Pair<int,int>(int.MaxValue,-1), costs.Count) noticing the side effect, that the List was full of referenced copies to a single object. Changing an element like myList[i].First = 1...

An unsigned integer is either ...
How do you implement a Stack and a Queue in JavaScript?
...
@cneuro Unlike C++, JavaScript is a garbage collected language. It has a delete keyword, but that is only useful to mark a property of an object as being non-present—which is different from just assigning undefined to the property. JavaSc...
What is code coverage and how do YOU measure it?
...an also roll some custom tools, like this article describes.
If you are a C++ shop, Intel has some tools that run for Windows and Linux, though I haven't used them. I've also heard there's the gcov tool for GCC, but I don't know anything about it and can't give you a link.
As to how we use it - co...
Real differences between “java -server” and “java -client”?
...t supports many of the same types of optimizations performed by optimizing C++ compilers, as well as some optimizations that cannot be done by traditional compilers, such as aggressive inlining across virtual method invocations. This is a competitive and performance advantage over static compilers. ...
