March of the Penguins-David Thornburg

Thornburg starts the session by giving a point for his new book. Might have to pick that up after the session. A book on open-source and open-source programs.

Linux started from a high school student in Helsinki, Finland

“I want students to use the programs they will use when they leave school.” and argument that has fueled the Mac vs PC debate for decades.

Sprint runs there how system on Linux.

Gartner Group study of 2000:

90% of the worlds 2000 largest companies will use open source software by 2010

70% will have migrated to Linux

Which OS should we be using and looking at for schools if 70% of the worlds largest companies will be using Linux.

State of affairs (estimated)

Windows 92%

Linux 5%

Mac 3%

Linux installations come at expense of Windows

edubuntu is an OS designed specifically for education

New Hampshire spending:

Win XP $72/year

Office $52/year

Inspiration $24

Photoshop $279

Sound Forge $45

Dreamweaver $189

LCSI Microworlds $89

That’s about $500 per desktop plus $140/year.

Benefits of free open source software

No license issues for multiple system installation

Developers are usually responsive

Can fix bugs yourself if you want

Limitations of free open source software

Titles are based on programmers interest

Forks can emerge (StarOffice vs. OpenOffice)

Commercial titles are coming!

When you don’t have to buy the basic programs it leaves more money for special programs need in the classroom.
