Encrypting your usb

Many students, teachers and parents make use of usbs. They are more handy and practical than the burning of CDs or DVDs. Well that was the positive point. What about many usbs getting lost or simply stolen? What about the files? What if a teacher has exam papers and it is lost? Parents and students too may have some sensitive material. Everybody has some private information that is intended for personal use. One would not wish that it will be freely circulated with other people, friends or not.

Hence the word encryption is appearing more frequently. Encryption involves a process where if the usb falls into the wrong hands, one cannot access any of the files encrypted. They are practically safe. One looks for a simple system and that is compatible with more than one operating system (ie mac, windows, linux and android). Today we are suggesting: AEScrypt.

GNU Backgammon

GNU Backgammon

Some of our readers want some open source program for fun. Yes we always present material for schools and it seems that we’re always presenting scholastic material! Ok. Let’s present something completely different. But it’s still open source and could be used on Linux, windows and Mac.

It is the famous game of backgammon. It is educational after all because students need to use their minds along the game!! Yet it is fun to play. There could be teams where students learn to collaborate in order to win a game.

Argunet - visualisation of an argument!

When it comes to writing, many students feel at a loss especially about argumentative writing. How can we help them? Well there is no easy solution but again, Open Source comes to our rescue. Today we are presenting Argunet which offers both an argument editor (similar to Argumentative) and a library of arguments that students can browse and analyze.

You can use it on a standalone system or in a client-server setup to encourage collaboration among students or debate teams. Operating System: Windows, Linux, OS X.

For some students, dividing their ideas in paragraphs or chapters is not enough. In this case, argunet, in a graphical way, helps students to organise and present their ideas in an easier way.

OpenStack: cloud solution for schools

Schools rely more on data and information nowadays. Teachers and students are on the move, they need to access some data not only when at school, but as well after school hours or during holidays. Where can one store all that information? What about security?

Today we are presenting a cloud solution: OpenStack. OpenStack is a cloud operating system that controls large pools of compute, storage, and networking resources throughout a datacenter, all managed through a dashboard that gives administrators control while empowering their users to provision resources through a web interface.  One can use OpenStack for networking and content delivery; management tools; deployment tools; application services and monitoring and metering.

Learn more about OpenStack's compute, storage, networking, take a tour of the dashboard, or dive in and learn how to get started with OpenStack today.

GNU Health

How secure are our computer systems in our hospitals? What if they are hacked? What about our personal data? Well open source is open source. If some one tries to install a code to extract information, because it is open source one can deduct it immediately because nothing is hidden. When one is using propriety programs one has to rely on a small number of people to solve problems. It might take ages and it’s rather costly. In the open source world, anyone can build or adapt (change) the program!

An official GNU project, this award-winning application combines EMR functionality with a hospital information system and a health information system. It was designed to comply with industry standards, and it's been adopted by the United Nations University. Operating System: Windows, Linux, OS X!

Some of our art students have asked for open source programs. Today we are presenting Alchemy. It could be installed on Windows, Mac and Linux computers!
Alchemy consists of a growing number of ‘modules’ that can be added or removed at will. Using a given module you can do things like:
  • Shout at the computer. Use your voice to control the width of a line or the form of a shape.
  • Draw ‘blind’. Turn off the canvas display and explore what shapes emerge from the ‘darkness’.
  • Create random shapes. Generate shapes that can be used as a starting point for characters, spaceships, or whatever shape you see in the ‘clouds’.
  • Mirror draw. Draw mirrored symmetrical forms in realtime.
  • Randomise. Mess up and distort shapes.

Global Features

Other global features place focus on the ‘process’ of drawing, letting you do things like:
  • Record a drawing ’session’. Automatically save the contents of the canvas to a page in a PDF file at set intervals.
  • Auto-clear the canvas. Start drawing on a clean slate at set intervals. Force yourself to start over fresh.
  • Switch the canvas. Automatically open your sketch in a more ‘conventional’ drawing application, either as a bitmap or vector file.
  • Avoid distraction. Alchemy has a very minimal interface, just a simple toolbar that dissapears magically, and a fullscreen mode to block everything else out.
Whatever you need to know before installing (or any help after installing), could be found on this webpage

3 D Slicer

Students studying medicine are really bombarded with propriety software! That means that it will only be allowed to be used against payment. This might be a hindrance to some students in some countries. But the news is not all black. Today we are presenting slicer.

3D Slicer is an open source software platform for medical image informatics, image processing, and three-dimensional visualization. Built over two decades through support from the National Institutes of Health and a worldwide developer community, Slicer brings free, powerful cross-platform processing tools to physicians, researchers, and the general public.

The same website from where one can download it, has practically everything: tutorials, notes, examples etc….But if you still prefer videos, then go for this link.
