Definition of FOSS Free Software Movement
− The freedom to run a program, for any purpose;
− The freedom to study how a program works and adapt it to a person’s needs. Access to the source code is a precondition for this;
− The freedom to redistribute copies so that you can help your neighbour; and
− The freedom to improve a program and release your improvements to the public, so that the whole community benefits. Access to the source code is a precondition for this
− libre vs gratuit
Richard Stallman is the founder

Making money with FOSS
Develop solutions
− Applications, Customisations,
Develop a service
− technical support demand for Linux system Administration Money on services, not on licences
Innovation – creating solutions
− Applications eg GIS

Learning to use Linux
Try an installation Learn the command line Do a project – create FOSS/Linux based
solutions and cost them− Web server− Desktop− Linux Terminal Server Project pilot
Certification?
