Next permutation: When C++ gets it right. An investigation into a classic algorithm for generating the distinct permutations of a sequence in lexicographical order.
Sums and sums of squares in C++. Reduce is a higher order function which applies a another function repeatedly to a collection of values, accumulating the result. Well known to functional programmers, reduce is also a standard C++ algorithm.
Stop the clock, squash the bug. Which is better, a clock which loses a minute a day or one which is stopped? An investigation into how we find and fix software defects.
Animated pair streams. Another look at the functional programming problem of generating an infinite sequence of pairs. An example of using the Python Imaging Library to generate an animated GIF.
The Lazy Builder’s Complexity Lesson. A discussion of algorithmic complexity, and a demonstration of how the C++ standard library allows programmers to write code which is both concise and efficient.
String literals and regular expressions. An article about string literals, escape sequences, regular expressions, and the problems encountered when mixing these together.
