BMW I-Bus monitor and decoder
/**
* BMW IBus Daemon reads BMW IBus data through serial port. It detects
* BMW board monitor(at least BM53) unit and steering wheel button presses
* from IBus data, maps them to key events and injects them to system event
* queue via uinput.
*
* It also can be configured to inject key events only in certain state like
* TAPE or AUX which can be useful if you want to hijack for example TAPE
* mode for other use.

Last active October 31, 2023 08:50
Generate a monochrome bitmap image in JavaScript using a byte-array. The image is generated such that every bit in the array is shown as either a black (1) or white (0) pixel.
/**
* depth: 1 - monochrome
* 4 - 4-bit grayscale
* 8 - 8-bit grayscale
* 16 - 16-bit colour
* 32 - 32-bit colour
**/
function drawArray(arr, depth) {
var offset, height, data, image;

A Sinus Activated Multi-Stochastic-Descending/Ascending (MSD/A) Feed Forward Artificial Neural Network (ANN) Computed by GPU via JavaScript and WebGL GLSL (GATO 2014) :: Fiddle: http://jsfiddle.net/Hnv8H/

<h3>A Sinus Activated Multi-Stochastic-Descending/Ascending (MSD/A) Feed Forward Artificial Neural Network (ANN) Computed by GPU via JavaScript and WebGL GLSL (GATO 2014)</h3>This web page attempts to outline an implementation for solving non-linearly-separable (NLS) classification and function approximation problems using a sinus activated feed forward neural network, trained via multi-stochastic-descension/ascension (MSD/A), and evaluated using the GPU via JavaScript and WebGL GLSL source code.
In order to overcome NLS using MSD/A, a sinus activation function: <b>sin(x)</b>, has been used in place of sigmoid: <b>1 / (1 + exp(-x))</b>, hyper-tangent: <b>htan(x)</b>, and/or averaging: <b>sum / count</b>, activation functions.
Although ANNs capable of overcoming NLS problems are said to be capable of entering any computationally complete state, actually finding and entering a specific state required to solve a real
