Basically, the Book cipher algorithm uses letters of subsequent words in some text or book as a key to encode a message. Figure 1 is the simplest form, usually called the "running key cipher." In this case, text (usually from a book) is used to provide a very long key stream. The book used is agreed upon in advance, while the passage used is ...

A low-footprint compression technique for when efficiency really matters. When I needed to implement a lossless data compressor for 16-bit ECGs (electrocardiograms), EEGs (electroencephalograms), and other medical signals in C on a 16-bit integer processor, I discovered how little value the majority of compression techniques were for my problem.
Adding a static member function to a class when its functionality could be implemented as a non-friend non-member decreases encapsulation by exactly the same amount as does adding a non-static member function. One implication of this is that it's generally a bad idea to move a free function into a class as a static member just to show that it's ...
