How does JavaScript .prototype work?
...
In a language implementing classical inheritance like Java, C# or C++ you start by creating a class--a blueprint for your objects--and then you can create new objects from that class or you can extend the class, defining a new class that augments the original class.
In JavaScript you first...
Dynamic type languages versus static type languages

Why does Windows64 use a different calling convention from all other OSes on x86-64?
... in low-level and compiler-generated "glue" code (think, for example, some C++ heap allocators zero-filling objects on construction, or the kernel zero-filling heap pages on sbrk(), or copy-on-write pagefaults) an enormous amount of block copy/fill, hence it'll be useful for code so frequently used ...
What is the optimal algorithm for the game 2048?
...ed @nneonneo highly optimized infrastructure and implemented my version in C++. This version allows for up to 100000 runs per move and even 1000000 if you have the patience. Building instructions provided. It runs in the console and also has a remote-control to play the web version.

Is MATLAB OOP slow or am I doing something wrong?
I'm experimenting with MATLAB OOP , as a start I mimicked my C++'s Logger classes and I'm putting all my string helper functions in a String class, thinking it would be great to be able to do things like a + b , a == b , a.find( b ) instead
of strcat( a b ) , strcmp( a, b ) , retrieve first...
Fastest way to determine if an integer's square root is an integer
...+Carmack+sqrt code, at least with my CPU (x86) and programming language (C/C++). Your results may vary, especially because I don't know how the Java factor will play out.
My approach is threefold:
First, filter out obvious answers. This includes negative numbers and looking at the last 4 bits. ...
How to get started with developing Internet Explorer extensions?
...ies (kind of like an STL for Microsoft's COM) and well as such is only for C++.
You could do COM Interop with C# and get away with doing it in C# but its probably going to be too hard for what it is worth.
Anyway, if you are interested in coding your own extension for IE (which is plausible if you ...
Benefits of prototypal inheritance over classical?
...ttle brother to Java, as a complementary language like Visual Basic was to C++ in Microsoft’s language families at the time.
This is bad because when people use constructors in JavaScript they think of constructors inheriting from other constructors. This is wrong. In prototypal inheritance obje...
Why would you use an ivar?
... memory usage (if done correctly).
Nontrivial Types
Example: If you have a C++ type, direct access is just the better approach sometimes. The type may not be copyable, or it may not be trivial to copy.
Multithreading
Many of your ivars are codependent. You must ensure your data integrity in multithr...
