This plugin protects your WPMU signup process against spambots with a simple math question. This plugin is based on the Block-Spam-By-Math plugin created by Alexander Grau. This only protects the new blog creation process and the new user creation process. If you wish to have individual blog protection use the regular Block-Spam-By-Math plugin on individual blogs.
This program interactively lets you encrypt and decrypt text as well as text files using a key system as well as a cipher.
Bifurcation diagram of the logistic map.
Random fractal curve (non-deterministic).
It creates fractal-like map plots from the simulation.
(See my other post titled "Dynamical Billiards Simulation" first!)
I had to keep image size and maxSteps small otherwise the calculation takes too long!
Levy Dragon Fractal Curve using Turtle graphics module of Python.
What is it about?
Learning to use the basic math operation (+, -, *)
Print out of statistics to show you where you are
Being able to define your own training sessions
What has changed?
IFS fractal dimension calculation using box-counting method.
Mandelbrot fractal using Python Image Library (PIL).
Archimedes method for calculating PI.
Combination of Sierpinski Square and 2 other square fractals!
It draws a random Diffusion Limited Aggregation fractal each time.
(Wait until the percentage reaches 100.)
5 Regular Polygon IFS Fractals.
This method uses inverse IFS transformations (assume new x, new y are known and x, y are unknown and solve the equation), and unlike IFS algorithm, it does not use a random number generator and neither the probability coefficients for each IFS...
C Fractal using recursion.
It draws a different spiral IFS fractal each time.
First and Second Order Ordinary Differential Equation (ODE) Solver using Euler Method.
This method uses inverse IFS transformations and it does not use a random number generator.
Polynomial Interpolation (curve-fitting) using Lagrange Polynomial.
