Why is auto_ptr being deprecated?
...ion of move semantics and the magic of rvalue references, it can do so considerably more naturally. It also "fits" with the rest of the standard library considerably better (though, in fairness, some of that is thanks to the rest of the library changing to accommodate move semantics instead of alway...
What are the best practices for catching and re-throwing exceptions?
... cleanup

What is the explanation for these bizarre JavaScript behaviours mentioned in the 'Wat' talk for Code
...ray) to a primitive returns its default value, which for objects with a valid toString() method is the result of calling object.toString() (§8.12.8). For arrays this is the same as calling array.join() (§15.4.4.2). Joining an empty array results in an empty string, so step #7 of the addition opera...

Benefits of header-only libraries
...might be used. When you separate the implementation, you usually do so to hide implementation details, and distribute the library as a combination of headers and libraries (lib, dll's or .so files). These of course have to be compiled for all different operating systems/versions you offer support.

Java's Virtual Machine and CLR
...then popping those operands off the stack whenever an instruction (add, divide, etc) needs to consume those operands. Each instruction pushes its results back onto the stack.
It's a convenient way to implement a virtual machine, because pretty much every CPU in the world has a stack, but the number...
