The Pagerank Algorithm

EyesRay render a 3D scene with the raytracing algorithm. Some specifics points are: a scene loader, the support of transparency, avaibility to generate images (ppm format)...

Jarsync is a Java implementation of the rsync algorithm, a deltacompression algorithm for fast network file transfers.

This library is a basic implementation from the GeoHash algorithm written in the java can be used to generate from the latitude and longitude a geohash code and reverse. For more information go to (http://en.wikipedia.org/wiki/Geohash)

The proposed algorithm is based on nonlinear derivatives to automatically select the best edge information. This algorithm can replace the classical derivative with the following benefits:- univocal edge localization for synthetic and real images- noise reduction with no regularization: the noise...

Hashr is a simple web utility that tranforms any given string into an cryptographic hash of the chosen algorithm. You can choose between 40 or more different algorithms. It was written in PHP and some javascript effects. What is it for? Well, mainly it was developed by me, for me. It's a tool I...
