How do a video card and a display device work together to create an image? These days, all displays are raster displays, and there is only one way.

Pipable functions allow us to write extension methods in C++. This overloads the pipe | operator to allow chaining several functions together, like the example below:

In cryptographic applications, it is often useful to wipe data from memory once it is no longer needed. In a perfect world, this is unnecessary since nobody would gain unauthorized access to that data; but if someone is able to exploit an unrelated problem — a vulnerability which yields remote code execution, or a feature which allows uninitialized memory to be read remotely, for example — then ensuring that sensitive data (e.g., cryptographic keys) is no longer accessible will reduce the impact of the attack. In short, zeroing buffers which contained sensitive information is an exploit mitigation technique.

Starting a thread in C++11 is as simple as declaring and instantiating a new object. We will analyze a simple multithreaded application to demonstrate how we can use the threads from the C++ standard library.

A good looking terminal emulator which mimics the old cathode display...

bin2c - A simple utility for converting a binary file to a c application which
can then be included within an application.

Memoization is a pretty well-known optimization technique which consists in “remembering” (i.e.: caching) the results of previous calls to a function, so that repeated calls with the same parameters are resolved without repeating the original computation.

This article examines various aspects of type declaration and deduction in both current standard
C++ as well as the forthcoming revised standard (C++0x), with an eye towards helping developers
understand how and why the effective type of a variable can be different from what's “obvious.”
Readers will find the article most useful if they are familiar with the basic rules for template argu

ment deduction, are aware of the difference between lvalues and rvalues, and have had some
exposure to the new C++0x features lvalue and rvalue references,
auto
variables, and lambda
expressions

Full devirtualization replaces given polymorphic by a direct call (that can get inlined later). Speculative devirtualization is a weaker form turning polymorphic call to a conditional testing whether the target is the predicted one and going by direct call path if it happens to be so and doing the indirect call otherwise.
