Ideals
5
God practices, wrong context ● Vern Ceder, CTO at Cantebury School, Fort Wayne ● He had worked for over a year convincing teachers to use a Linux desktop at their school ● He invited at LUG enthusiast to show how Linux may work in practice
6
The LUG enthusiast: ● Apache as the biggest success in FOSS, showing it ● Command line as a great tool, showing it ● Thick clients are great, installing and tailor each pc bottom up ● Free Flash player (Gnash) and no proprietary movies ● doc and docx are really bad
7
A LUG enthusiast may recommend a 1996 Linux desktop
8
It's 15 years with development since 1996 The 2009 version > 7000 end user applications
9
Teachers presented the 1996 desktop? Worst system ever! Vern had to restart the session showing GCompris and KDE Edu The project was delayed with half a year...
10
Teachers expects: ● A Learning Management System – They could not care less about Apache ● A graphical desktop with GUI apps – Command line, newer! ● As little installing and configuration as possible. USB support is mandatory ● Flash, Java and video must work out of the box ● No problems with doc and docx

Just give teachers what they want

Perception and realities ● To few apps, nobody supports Linux? – No, to many applications. It's difficult to choose ● To many desktop alternatives? – Wrong, it's two alternatives in practice. – Applications blends in nicely. E.g KDE 4 apps got GNOME look and vice versa ● Must learn what's used in businesses – Yes, and free software will be included in 80% of the software products in 2012 according to Gartner – Who know that a web browser would be the most important tool 15 years ago?
26
Client types ● Thick clients – known as stationary PC's. SW runs locally ● Thin clients – SW runs on servers. X11 clients ● Graphical clients – SW runs on servers. Citrix or FreeNX clients. Local OS. Network saturation stops graphics... ● Low Fat (Diskless) clients – SW comes from servers. SW runs locally ● Laptops/Netbooks/MiD – SW runs locally. Wireless network challenges
