The Me ● 28 years old student ● Education as a primary school teacher ● Education, CS and CL at the University of Zurich (Switzerland) ● Doing Free Software work since 1998 ● Mostly in the context of education and teaching ● Grown up in Ried-Brig in the Middel of the Alpes KDE@School - akademy 2007 3
The School ● Primary school Ried-Brig in the South of Switzerland ● Population: approx. 1800 human beings ● School: 8 classes and some more teachers ● A rather conservative region of Switzerland ● But the school used PCs for quite some time KDE@School - akademy 2007 4
The Problem ● At the beginning of 2005 ● Old computers (3-5 years old) with MS Windows 98 ● The kids liked it to reconfigure the system ● They don't have to much money ● Finally the teachers PCs crashed for a last time in his life KDE@School - akademy 2007 5
The Proposal (1 of 2) ● An application server thin-client solution with FreeNX on GNU/Linux ● The Server: a 1000 € PC with 2 GB RAM ● The Clients: old computers of the school ● The Software: – Debian GNU/Linux Sarge – KDE 3.3.2 or something – FreeNX and NXClient from nomachine.com KDE@School - akademy 2007 6
The Conditions (2 of 2) ● Their conditions: – The (proprietary) windows education software has to work on the new system – Internet, text processing, printing, etc. ● My conditions: – First: All the teachers must agree with the change to a new system (and feedback) – A possible participation in a research project or evaluation of me KDE@School - akademy 2007 7
The Present ● The system is in use since 2 years... ● Last year they bought 2 new servers because they wanted more clients ● There is a computer room and 2 or 3 clients in every classroom ● The pupils power the clients just off (no shutdown) ● The original school administrator changed KDE@School - akademy 2007 8
The Future ● NX session from at home ● An update to Debian GNU/Linux 4.0 Etch and therewith KDE 3.5.5 ● A Windows terminal server as an addition (see what I can do with WINE nowadays) ● Remote future: – Change to KDE 4.x – Exchange some proprietary education software with free alternatives KDE@School - akademy 2007 9
