Val (and an AUV) on TV in New Zealand!

Here’s a link to Channel 3 News in New Zealand where Val was working last month: Underwater Robot Explores Marine Mystery

Exciting stuff! Val was on the project, working with Dora the AUV (from Art Trembanis’ group at the University of Delaware). They were in New Zealand helping local scientists to collect data to understand the ecology of the Tasman Bay, and why the shellfish populations have diminished so rapidly in recent years.

Val is in the video – you can see him throwing the AUV overboard for a mission – he’s famous!!

OOoLatex for OpenOffice Draw

When I used to make diagrams for papers and assignments in school, I liked using Omnigraffle (back in the good old days when my Powerbook was in operation). It was really simple, and had a lot of “stencils” with useful symbols for things like circuit diagrams. I was hoping to find something similar for Linux, and started looking around.  The simplest thing I’ve found so far is OpenOffice Draw.  I started putting together a little ray-tracing sketch to put into my LaTeX document.  I was able to add the basic shapes, give it some color, I could even add symbols.  But I couldn’t make a subscript.  This is probably a small detail to most people, but it’s a show-stopper for me.  So I googled around a bit, and came upon OOoLatex.  I think it might help me do what I need to do – and more… I’ll have to give it a try. Part of the appeal of Omnigraffle was its ease of use, and having to add a set of macros from a independent source, just to add subscripts, seems like overkill.

I found this description of installing OOoLatex on an Ubuntu forum – it’s from 2007, but I think it will be alright.

Install dependencies:
mkdir ooolatex
cd ooolatex

Install mathematical fonts:
mkdir OOoLatexFonts
cd OOoLatexFonts
wget http://mesh.dl.sourceforge.net/sourceforge/ooolatex/OOoLatexFonts.zip
unzip OOoLatexFonts.zip
cd ..
sudo mv OOoLatexFonts /usr/share/fonts/truetype/.
sudo fc-cache -f /usr/share/fonts/truetype

Install binaries for EMF – first download the emf binary from http://sourceforge.net/projects/ooolatex/files/, then
tar -xzvf latex2emf_Linux_i386_binary.tar.gz
cd latex2emf_Linux_i386_binary/
sudo ./install.sh

Install OOoLatex – download the ooolatex .oxt file for linux, then go to the directory where it was downloaded.
/usr/lib/openoffice/program/unopkg.bin add OOoLatex-4.0.0-beta-2-linux.oxt

*wow – huge GNU license agreement comes up in terminal.

Usage:
Go to View –> toolbars –> ooolatex

*sigh.

It doesn’t work in draw (but does in OpenOffice Word). That was a bit of a waste of time for me since I’d rather just go completely to Latex for my documents. I guess I still haven’t found the right diagramming software. The search continues.

Ah-ha! I just found something that I think will work! http://www.skencil.org/
