For casastristes.org we are making different visualizations of the housing situation in Spain. Also Java is a pain in the ass on the web, in two of them we are using Processing comparing new inhabitants with newly constructed houses and free real estates per provinces. In the following article I show the advantages of using SVG graphics when mapping information.

Googe Maps loads about 400 kByte for each visit to casastristes.org. Sometimes I prefer to implement a static map instead but still using latitude and longitude values for mapping the places. In the following example I show how to convert lat/lon values to x/y coordinates for the use on a static map.
Some weeks ago I did a fresh setup of Ubuntu 6.10 i386 on my laptop. Since my last install from zero – it was Ubuntu 5.10 AMD64 – it got much more easy to configure wireless network on my Acer Aspire 5021 WMLi. But still there are a few steps which are quite particular to resolve (there are a lot of forum threads discussing the issue) so I gonna describe step by step how todo it:
This week I’m doing a Arduino prototyping workshop at ESDI as part of Summer-School at Ramon Llul University. Two of the creators of Arduino, Massimo Banzi and David Cuartielles, are giving an introduction to electronic prototyping tecnics using this nice free hardware called Arduino. After giving an introduction on Arduino basics and setting up an example of interacting with the Arduino board troughout Processing we saw some examples of Arduino prototypes and installations (Virtual Fishtank, Virtual Sumo, Punching Bag) implemented with Ardunio.
Thanx to the people from Arduino to offer a Linux version. As there is no binary packet for any distro till now you have to compile the software by yourself. This forum thread and this article discribe the steps to get Arduino up and running on Linux but actually I noticed some differences on my machine. I’m running the AMD 64bit edition of Ubuntu 5.10 “Breezy Badger”.
