"Practical Design Patterns in C" is a hands-on book about a way of putting (commercial) software together
Basic approaches are small, simple and generic descriptions of how a potential solution to a problem can be found. Find in this section a sampling of such approaches cast in a concrete problem-solution context that demonstrates the mechanics of the process
Software Construction section is a two-part tutorial exploring the incremental approach. The first part is an Arithmetic Expressions Calculator implementation based on the Shunting Yard algorithm with an interactive visualization applet. The second part is an adaptation of the same algorithm for Boolean Expressions Evaluator For Strings
g is a small and simple language that I use to record the solutions to straight edge and compass construction problems
Experiments section deals with my experiments with problem solving where I put my solution paths to various problems on public display
In Triangle section I record the many ways in which this ubiquitous geometric object can be constructed
Inversion is a section dedicated to inversion of a real plane with respect to a circle. Inversion in a complex plane with respect to a circle and inversion with respect to a sphere are in the works
Gear Clocks is a three-chapter book on the fundamentals of the inner workings of these beautiful objects. Find here a mix of a large amount of mathematics and physics along with practical instructions
Tutorials:
Kombinatorix Primordial is an introductory tutorial that gathers all the basic combinatorial counting principles in one place painting one, hopefully, coherent picture of the subject
GCD, the Euclidean Algorithm is a small tutorial that explains the inner workings of a classical way of computing a greatest common divisor of two integers
This site was created on OpenSuse with vi and tested with Firefox. The geometric drawings were done with GeoGebra, OpenSCAD and GIMP, the tables - with LibreOffice. The math is rendered by MathJax via a secure server
