Steve Hargadon–Introduction to Open Source

July 1, 2008

This was a session on July 1.  

Came in late to this class–Steve’s talking about Wikipedia.  I came here to this session to see if I can enhance my understanding enough to go back to my district and solidly share about what OpenSource is.  After this session, I definately was better versed in my understandings of the whole thing.  I appreciate Steve’s clear descriptions and easily understood explainations of the beginnings of the movement.  I have a clear vision of what we are doing here, and what’s happening. 

Below are my notes from the session:

 

CreativeCommons:  Sharing and how to share with permission–how to understand the liscensing behind creative commons.  I like that because it seems to allow open communication.

Web 2.0–Wiipedia–Open source helps us create the products we end up buying.  That is the heart of open source.  

Foss or Floss

Free Open Source Software or Free (Libre) Open Source Software

Free means no cost, or free means free to use and change. Free in open source software use – it is meant to be free to use.  “free” means initial cost.  But there is of course there is a cost–training, implementation.  

Richard Stallman:  scary picture:  🙂  at MIT there was a free exchange of programs.  Code was exchanged. Since then it was not alowd to share programs.  Richard was an instigator of sharing software.  To be able to look at the code and share it.  He started the free software movement.  This was a fringe movement.  This was relabled as “open Source”  –softeware you can look at the “source” code.  

He had a great vision because as we all have no money in education, we now have lots of opportunities to use and obtain programs at no cost.  he had 4 freedoms:

0:  freedom to run the program

1: freedom for redistribution for any purpose

2: freedom to study how it worked

3:  freedom to  improve it

 

BECTA:  this is a study in Britain touting the benefits of using open source tools.

If we want our workforce competitive, we need to be teaching them open source softwares

 

GPL:  Key GNU Pubic License Terms

  • lisensee may run the program
  • licsencee may copy and distribute verbatim copies of the program source code
  • may create deritive works of the program
  • may distribute deritive works.
Three primary categories of open source software:
  • Operating systems:  linux
  • Applications
  • Content
We could use open source software instead of paying for it.
Why use it:
Cost savings, stability, no forced upgrades, access, access to a skilled community of developers, new developments, and just the global collaboration is a benefit.
Reasons for sing FLOSS:  
  • functionality
  • similar functionality
  • customize solutions
  • uses older computer hardware – 
  • WE should be using old PCs — it is good for the world.
Why not use open source
  • it can be free like a puppy-this means that even though it is free, there is work involved in migrating and maintaining as well as training for it.
  • can cost you money to migrate
  • migration is hard
  • uncertainty to the development model:  All of the issues
  • Lack of intellectual warrantees and indemnities
  • lack of performance warrantees
  • must follow the licensing if you change the code
ubuntu:  opensource operating system-Steve uses this alot.  He says it is a great program.  And 
Installing programs:
  • distributions of linux
  • .iso is the file format to create an image of a whole CD. So you want to crate an image and a whole CD.
  • You burn it and create the CD image.
  • Restart your computer with the CD in it and it will give you an option to try the ubuntu.   You can run the operating system from the CD.  So you can test the program out.  You can then install it and do a dual boot, or just totally install it.  (He is talking about the PC, not the MCA).  
  • With ubuntu you get lots of programs:  open office, etc.
