Chromacoding – hiding secret files in images

Here is a technical report I have written in 2006, which follows an interesting route to increase the steganographic capacity of lossless compressed images such as PNG files. This is done by using a color space which is perceptually more linear than the technical RGB cube: CIELab (or CIELuv).

Why’s Poignant Guide to Ruby (LaTeX PDF)

If you are interested in Ruby, or already a Ruby programmer, you might be interested in a wee little precious gem called Why’s Poignant Guide to Ruby, written by why the lucky stiff.

Sketchy rendering of vector fields

When fluids, gases or electrostatic fields are simulated, the result is a vector field, which consists of an array of vectors, which point in some direction and have a certain length. The longer the vector, the higher the pressure, velocity or electrostatic charge.

When fluids, gases or electrostatic fields are simulated, the result is a vector field, which consists of an array of vectors, which point in some direction and have a certain length. The longer the vector, the higher the pressure, velocity or electrostatic charge. Visualization is usually done using arrows in a regular grid, as depicted ...
