DNALinux VD Python for bioinformatics

DNALinux Virtual Desktop Py4Bio is ready!. This edition is called Py4Bio because is the Linux distribution is included in the book Python for Bioinformatics. Including a Virtual Machine in a book allows the reader to have the same environment used by the author so he could focus on following the examples with confidence.

This release is based on the last Xubuntu "stable" or "LTS" version (8.04). It has all the programs in Xubuntu plus both desktop and server bioinformatics applications. As a server DNALinux includes BLAST, Primer3Plus and MySQL. Full list of pre-installed bioinformatics software is available here: [link].

Since this distribution is a 12Gb VMWare Virtual Machine, it is compressed with 7z (to 2.3Gb) and uploaded using bittorrent protocol. Torrent file is available from the download page: http://www.dnalinux.com/download.php. Please seed the image if you can.

Java Program Uses Neural Networks To Monitor Games

Java developers have used the open source Neuroph neural network framework to monitor video game players while they play and then provide helpful situational awareness, such as audio queues when a power-up is ready or on-the-fly macros for combo attacks. The developers have published an article describing many of the technical details of their implementation. 'There are two different types of neural networks used by DotA AutoScript. The first type is a simple binary image classifier. It uses Neuroph's "Multi-Layer Perceptron" class to model a neural network with an input neurons layer, one hidden neurons layer, and an output neurons layer. Exposing an image to the input layer neurons causes the output layer neurons to produce the probability of a match for each of the images it has been trained to identify; one trained image per output neuron.
