What is a semaphore?
...xes and semaphores is historical, as it dates all the way back to the 1974 invention of the Semaphore (capital "S", in this article) by Djikstra. Prior to that date, none of the interrupt-safe task synchronization and signaling mechanisms known to computer scientists was efficiently scalable for use...
Why do C++ libraries and frameworks never use smart pointers?
...ith smart pointers (pre C++11):
non-standards, so each library tend to reinvent its own (NIH syndrom & dependencies issues)
potential cost
The default smart pointer, in that it is cost-free, is unique_ptr. Unfortunately it requires C++11 move semantics, which only appeared recently. All othe...
Golang production web application configuration
...gh you can serve directly from Go thanks to net/http, there's a lot of "re-inventing the wheel" and stuff like global HTTP headers involves some boilerplate you can probably avoid.
supervisord for managing my Go binary. Ubuntu's Upstart (as mentioned by Mostafa) is also good, but I like supervisord...

Are Java static calls more or less expensive than non-static calls?

If you take just a tiny look under the hood, you will immediately see that this is so: docs.oracle.com/javase/specs/jvms/se7/html/…

What is object slicing?
...ever, the object derived cannot be copied completely, as the class B could invent additional member variables which are not in its base class A.
Therefore, to call wantAnA, the compiler will "slice off" all additional members of the derived class. The result might be an object you did not want to c...

Custom mock implementations are much cleaner in the long run, and have the benefit of being able to be documented - unlike dynamically generated proxies. Furthermore, unless you...
