Python naming conventions for modules
...
Windows versions, or DOS.
When an extension module written in C or C++ has an accompanying Python
module that provides a higher level (e.g. more object oriented)
interface, the C/C++ module has a leading underscore (e.g. _socket).

Override compile flags for single files
...when this source file builds.
You should be able to countermand the -Weffc++ flag for foo.cpp by doing
set_source_files_properties(foo.cpp PROPERTIES COMPILE_FLAGS -Wno-effc++)
This should have the effect of adding -Wno-effc++ after -Weffc++ in the compiler command, and the latter setting wins....
Are Java static calls more or less expensive than non-static calls?
... near the optimization that Hotspot does), or some remembered trivia about C++ (in which a dynamic call uses one more memory access than a static call).

Mutable vs immutable objects
... course that you're using a language which makes this a tenable opinion (C/C++ makes this very difficult, as does Java). In short: the advantages depend somewhat on your problem, but I would tend to prefer immutability.

Technically, why are processes in Erlang more efficient than OS threads?
...ystem. That's really what's wrong with programming languages like Java and C++. It's threads aren't in the programming language, threads are something in the operating system – and they inherit all the problems that they have in the operating system. One of the problems is granularity of the memor...
C/C++ macro string concatenation
...
Just for the record, "s""1" is valid in C (and C++). They are two tokens (string literals) that the compiler would concat itself and threat as one token.

Wrapping a C library in Python: C, Cython or ctypes?
...marks on the various options.
I might be more hesitant if I had to wrap a C++ library with lots of classes/templates/etc. But ctypes works well with structs and can even callback into Python.

Accessing private member variables from prototype-defined functions
...
"scoping in reverse" is a C++ feature with the "friend" keyword. Esentially any function should define it's prototype as it's friend. Sadly this concept is C++ and not JS :(

Efficiency of premature return in a function
... of mine I'm trying to optimize. For the major C-like languages (C, objC, C++, Java, C#, etc) and their usual compilers, will these two functions run just as efficiently? Is there any difference in the compiled code?

How the single threaded non blocking IO model works in Node.js
...lar fashion. The internal thread architecture is something like this:
The C++ threads are the libuv ones which do the asynchronous I/O (disk or network). The main event loop continues to execute after the dispatching the request to thread pool. It can accept more requests as it does not wait or sle...
