Serpent Cipher Explained: How It Works, With Code in C, C++, Java, Python and C#
The AES finalist with a 32-round safety margin: how Serpent works, why two correct versions disagree, and four mistakes that a round-trip test misses.

Abstraction in Object-Oriented Programming: Abstract Classes and Interfaces in C++, Java and Python
How abstract classes, interfaces and Python protocols separate what code does from how, with a testable clock example in C++, Java and Python.
Encapsulation in Object-Oriented Programming: Private State and Invariants in C++, Java and Python
How private state and checking methods keep an object valid, why a getter can leak it, and how Python gets encapsulation from properties and convention.
Inheritance in Object-Oriented Programming: Types, Examples in C++, Java and Python, and When Not to Use It
One base class and two subclasses written in C++, Java and Python, the five types of inheritance, and why a subclass counted six tags when three were added.
Multiple Inheritance in C++: Interfaces, Name Clashes, the Diamond Problem and Virtual Bases
What changes when a C++ class has two bases: offsets, ambiguous names, a duplicated base in the diamond, and who constructs a virtual base class.
Inheritance in C++: Access, Constructors, Overriding and the Pitfalls That Compile
How C++ inheritance works and where it fails quietly: default private bases, hidden overloads, a missing virtual destructor, and arrays of derived types.
DirectX Components Explained: From DirectDraw to Direct3D 12
A history of DirectX from Windows 95 to DirectX 12 Ultimate, with pixel formats, palettes, pitch and double buffering explained in tested C code.
Heap Sort in C, C++, Java, Python and C#: Heaps, Sift-Down and Real Costs
Heap sort is O(n log n) in place on every input. How the heap lives in an array, code in five languages, and what the guarantee costs against quicksort.
Merge Sort in C, C++, Java, Python and C#: Top-Down, Bottom-Up and Linked Lists
Merge sort is stable and O(n log n) on every input. Code in five languages, measured comparisons and allocations, and four mistakes that compile.
Selection Sort in C, C++, Java, Python and C#: Swaps, Stability and Speed
Selection sort always makes n(n − 1)/2 comparisons and at most n − 1 swaps. Code in five languages, measured counts, and three mistakes that sort.
Insertion Sort in C, C++, Java, Python and C#: How It Works and What It Costs
Insertion sort moves one element per out-of-order pair. A traced example, code in five languages, and measurements that show what that costs.
