Hot Deploy Java code/ ATG components on JBoss

Pretty simple, on a production environment you start JBoss with its run file and a series of commands, which then picks up your EAR file from...

Setting Database Connections in JBoss/ ATG

ATG communicates to a database via JBoss via a dynamo server setup or in your home/localconfig directory if you’re not using specific dynamo servers. In this...

Arduino + Processing – Make a Radar Screen – Part 3: Visualising the Data from Sharp Infrared Range Finder

So I had some luck with getting the Sharp Infrared range finder working and I’ve now plugged this on to my servo rig to see if...

Arduino – Using a Sharp IR Sensor for Distance Calculation

Well, looks like my sonar sensor (SRF05) is a just a tad inaccurate for precise measurement as I found from my radar screen I made (Arduino...

Arduino + Processing: Make a Radar Screen to Visualise Sensor Data from SRF-05 – Part 2: Visualising the Data

This is where all the work is done to read an interpret the values from the servo and the sensor. If the readings are to erratic...

Arduino + Processing – Make a Radar Screen to Visualise Sensor Data from SRF-05 – Part 1: Setting up the Circuit and Outputting Values

First things first, we need to build our circuit. This is the easy bit! We’ll be using the Arduino to control a servo that will rotate...

Arduino – Basic Theremin meets Processing!

My last theremin involved a small speaker. Now I’ve replaced the speaker with my PC, using processing to pick up the values from the SRF05 ultrasound...

Theremins are cool. Fact. You may also have heard of them as either aetherphone/ etherophone or termenvox/ thereminvox. Essentially its an electronic music instrument that plays...

Pretty similar to setting up SSL on unix/linux and actually not that hard to do. Just a few things to remember as a checklist. If your...

When calculating data transfer rates we have to understand a few things. Firstly for this example we are ignoring network latency and additional packet data that...
