FOSS Resources: “the big stuff”
(servers, operating systems, database management)


In addition to the large number of FOSS applications such as word processing, internet browsers, multi-media and design programs, etc. which are available to educators, there are also FOSS resources available for educators who do not have access to the necessary technology for creating networks, connecting students to the web, or running the aforementioned applications.
Operating Systems and Workstation Software

Every computer needs an operating system to run. Microsoft Windows and MAC OS operating systems can be very costly. LINUX is a free operating system that educators can use instead.


  • Comments about Linux from the General Information section of the Linux website.

- “Apart from the fact that it's freely distributed, Linux's functionality, adaptability and robustness, has made it the main alternative for proprietary Unix and Microsoft operating systems.”

- “…there are now a wide range of applications that run on Linux and it can be used by anyone regardless of his/her knowledge of computers.” Most of the FOSS software that I came across while browsing the web, such as the word processing applications, web browsers like Mozilla, and multi-media applications were all compatible with Linux.

  • In the Linux Website’s Applications page we find what I would call a fairly comprehensive list of FOSS applications, tools, and utilities, divided into categories such as “Administration” or “Networking.” There is also a link to find distributors for the various applications listed.

  • For those who struggle with computer technology, there are free online Linux courses, accessed from the Linux website, which are available to help familiarize users with the OS and its applications.

Servers/Setting Up Networks

In media labs or classrooms with a number of computers, instead of installing applications on every workstation, which is both time-consuming and expensive, it often easier and much less expensive to set up a network and use “thin clients,” which are, according to the FOSS Education Primer “computers with a network card, graphics card, monitor, keyboard and mouse,

but without hard disk, CD-ROM drive and operating system” that are run by a server (FOSS Education Primer, p. 6). There are FOSS resources available to educators who wish to set up such a network system.

  • Linux Terminal Server Project (LTSP)

- LTSP provides the free necessary software for setting up a network and in turn saving time and money.

- This is the website: ltsp.org

- The website’s description of LTSP: “LTSP is an add-on package for Linux that allows you to connect lots of low-powered thin client terminals to a Linux server. Applications typically run on the server, and accept input and display their output on the thin client display.”

  • A real life example of how this technology can be used: Linux in Kanuur, India Schools. (this example is also referred to in the FOSS Education Primer, p. 6)

  • In general, we would also like individuals on a network to be able to print from their own workstations. There are also FOSS resources available to make this possible.

- Samba (www.samba.org)

- Samba helps with interoperability, that is, if a network is using a Linux server and individual clients that are running Windows operating systems, samba allows users who are working at Windows workstations to print or send files over the network even though they are not running Linux at their workstations.

Database Management Systems

A database management system is: a collection of programs that enables you to store, modify, and extract information from a database. There are many different types of DBMSs, ranging from small systems that run on personal computers to huge systems that run on mainframes.
(definition from webopedia.com)

Examples of DBMSs: school/university library systems, databases of research/information sources such as ERIC, JSTOR, etc.

v MySQL (www.mysql.com)

-websites such as Craigslist, Wikipedia, Ticketmaster, Yahoo (article on Yahoo's use of MySQL) and even NASA (NASA switches from commercial to free source management system) use MySQL



v PostgreSQL (www.postgresql.org)

Gestalter

(January 20, 2003)

Gestalter is a free vector drawing program. The user interface is loosly modelled after the famous Illustrator (tm) by Adobe. The central element is the Bezier curve used as a base part for almost every other object. Complex paths are possible, compound paths can be constructed, grouping of elements is enabled and everything can be screened by a mask. The object model is multi-layered (though the user interface for editing layers is not implemented yet). (GNU Public License)

Gimp

(May 20, 2002)

Gimp is an image manipulation tool for X Windows. ( GPL)

ImageJ

(August 05, 2002)

ImageJ is a public domain Java image processing program inspired by NIH Image for the Macintosh. It runs, either as an online applet or as a downloadable application, on any computer with a Java 1.1 or later virtual machine. It can calculate area and pixel value statistics of user-defined selections. For instance, it can measure the number of stars, or galaxies in a photo, or measure the area in a picture of a cell or a forest. It can measure distances and angles. It can create density histograms and line profile plots. It supports standard image processing functions such as contrast manipulation, sharpening, smoothing, edge detection and median filtering. (Public Domain)

Kavlon Coloring Book

(January 11, 2004)

A coloring book program. Allows the user to pick from a collection of pictures and to color the selected picture in. (GNU Public License)

It requires SDL, SDL_image, SDL_ttf and, optionally, SDL_mixer. It runs on various platforms including Linux, Windows, MacOSX, and BeOS, and has been translated into over 45 languages.

Superficie (surface) is a small program that allows to visualize 3D surfaces, and to have certain interaction with them. It allows to rotate, to move away, to show illumination, etc. on the surface at issue.

LiveSupport Radio

LiveSupport Radio is the first free and open source radio management software that provides colleges live radio capabilities as well as remote automation in one integrated web based system

What is a FOSS? FOSS is a Free Open Source Software.

Our goal with this blog is to make FOSS Resources available to you, the educator. These Resources can be used to help alleviate cost for online technology based education. These resources can be used for in school or online sessions. All of the Resources are free!

Educators everywhere who are entering the virtual world are faced with one tough dilemma...cost. FOSS is one way to cut down on the software technology costs because these software programs are free to download and can be shared. Sometimes maintenance can be a small fee but nominal compared to proprietary software (i.e. Microsoft Office). FOSS is also available globally so teachers can be connected internationally.

To learn more about FOSS please got to: www.ison.net and read the FOSS Education Primer.

Hi guys, I just wanted to let you know I got on here. It was a little tricky but obviously I made it. MEL
