Wiki Module for Drupal

Submitted by chris on Sat, 03/20/2010 - 16:11

As explained in Drupal Wiki I wrote my own drupal module to wrap PMWiki to give me a fairly rich wiki in my Drupal site.

Download the Wiki module HERE

To install the module

  • Unpack the module file in the modules folder of your Drupal installation.

Poor Man's Digital Survey Device

Submitted by chris on Wed, 10/17/2012 - 07:12

This is a low cost device for Cave Surveying, it uses an Android Phone and should work with any Backlit Laser Distance Measure. It needs a custom enclosure (case, box, whatever) that allows buttons to be pressed on both devices. For the proto type I used:

A £50 Laser Distance Measure off ebay

Low cost Laser Distance Measure

 

A Samsung Galaxy Y Phone

3D, three ways

As a result of some people wanting to display cave surveys on the web, I started looking at options for displaying 3D graphics in a web browser. I ended up implementing more or less the same thing in SVG, Flash and as a Java Applet. What we wanted was real time three dimentional rotation and translation of a set of points, surfaces and bitmaps and all these technologies seemed, at least on paper, capable of displaying this kind of data.

This project kicked off with the desire to have an easy way to measure distance travelled in a cave.

Here are some free/open source projects that I have developed.

Digital-Survey-Device- A low cost Digital Survey Device for surveying caves

Optical-Flow-Odometer - Measure distance travelled from a video stream by adding a cheap laser pointer into the mix

Wiki Module for Drupal is a PMWiki modukle for Drupal

Survey Digitiser is an application to allow on-screen digitisation of scanned maps and plans

Musings

Here are some things that make me think, and some ill-informed musings.

I have a passing interest in art and philosophy and at the moment where I've got to is "Art is the mathematics of emotion"

Maths is an abstract way of representing a concept. By understanding the mathematical abstractions it is possible to exchange ideas about the world around us. There are many forms of mathematics, it covers a broad range of concepts. Similarly art is a way of conveying a feeling, emotion or range of feelings and emotions to another person.

Using Drupal as a Wiki

I decided to move my presonal site over to Drupal. The old site was partly manually created HTML and partly PMWiki. I liked PMWiki because it was fairly simple and worked well. One of the add-ons I used was syntax highlighting for code that I post. Having looked around at a few CMS's I decided Drupal was probably a good fit for my requirements, well coded, well supported and with more modules that I could shake a stick at.

So how to do a wiki with syntax highlighting in Drupal?

Read an XML document

below is the basic Java DOM approach to reading an xml document (file) into memory 

DocumentBuilderFactory docBuilderFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder docBuilder;
Document doc;
try {
	docBuilder = docBuilderFactory.newDocumentBuilder();
	doc = docBuilder.parse (new File("FileName"));
}
catch (ParserConfigurationException e) {
	e.printStackTrace();
}
catch (SAXException e) {
	e.printStackTrace();
}
catch (IOException e) {
	e.printStackTrace();
}
