Mahara | ePortfolios

Mahara is an open source ePortfolio and social networking web application originally created by the government of New Zealand. It provides users with tools to create and maintain a digital portfolio of their learning, and social networking features to allow users to interact with each other. Mahara content management system provides users with blogs, a resume builder, a file manager and a view creator - a tool to help users create arrangements of their content in a particular way for others to see.

The eportfolio site http://myportfolio.school.nz, provided by the New Zealand Ministry of Education, free-of-charge for all New Zealand schools, is powered by Mahara

Inkscape | Vector Graphic Editor

"An Open Source vector graphics editor, with capabilities similar to Illustrator, CorelDraw, or Xara X, using the W3C standard Scalable Vector Graphics (SVG) file format.

Inkscape supports many advanced SVG features (markers, clones, alpha blending, etc.) and great care is taken in designing a streamlined interface. It is very easy to edit nodes, perform complex path operations, trace bitmaps and much more. We also aim to maintain a thriving user and developer community by using open, community-oriented development." (Link)

How safe are your blueprints?

James Bond and Knight rider might have had to resort to using tiny cameras to take photos of secret blueprints, but it seems today's data thieves don't need to go to such lengths. There are reports of a virus spreading through installations of AutoCAD that is sending sensitive data to email addresses in China.

Free software has fewer viruses, partly because everyone can see the code (warts and all) so everyone can spot potential security breaches. Sadly if you keep your code hidden from your users, you're really just helping writers of viruses do their work.

If you're worried about the security of your CAD data, use something open source like Draftsight.

Draftsight: free CAD software

Good quality open source free CAD software has been difficult to find in the past, but earlier this year 3DS released Draftsight, a product that comes close to industry heavyweight AutoCAD.

"DraftSight is a professional-grade, open 2D CAD product for users who want a better way to create, edit and view DWG files. DraftSight is easy to use and is available for professional CAD users, students and educators to download and activate for free."

It supports DWG files so even if you just want to open AutoCAD files to view, Draftsight can do it.

Open Source Physics: Tracker

I discovered this neat tool when learning about the physics of Angry Birds. Not only does Tracker identify and track objects frame-by-frame through a video, it also records and graphs this data for you. It comes with quite a few experiments installed and, in the hands of a good Physics teacher, would form the centre of a very interactive unit on motion and movement. I can imagine students the world around grabbing their cellphones to record video of all manner of objects 'bouncing'. Hmmm. Does my glass of chocolate milk fall at the same rate as a bowl of noodles?
It's an easy-to-use tool that allows students to become better askers of questions and designers of experiments instead of becoming better memorisers of someone else's data.

World Wind: Open Source Google Earth?

World Wind is by no means as full-featured as Google Earth, but if you just want to play Atlas and spin the world around, it's a good option. To install under Linux, look for worldwind in the software channels, but the java version of the software runs on any platform. Best thing about it is that the software is open source and the imagery is not owned and copyrighted by [insert giant corporation here]. There are some nice Java webstart demos here too: http://worldwind.arc.nasa.gov/java/demos/ showing things like loading .kml files, mapping elevations, annotations, geo-mapped photos, earthquake information etc.

Yo Frankie!

One of the most high-powered, full-featured open source applications is Blender 3D. It's an incredibly powerful 3D modelling application that has been used to make short films like Big Buck Bunny and Elephant's Dream. So what do all those 3D characters do after their film careers end? They get jobs in computer gaming. Using all of the models and landscapes from Big Buck Bunny, the blender community has created Yo Frankie!, a 3D game with very impressive graphics, that is free for anyone to download and play.
