I worked nearly 20 years as -certified engineer in the department for plant design and layout of an -international company for machinery and equipment. Since 2011 I'm a -certified technical writer (tekom e.V.) and doing technical -documentations for a steam turbine manufacturer. From April this year -I will manage the department of technical documentation at a -manufacturer of automation and assembly line engineering.</p> - -<p>My first contact with linux was around 1993. Since that time I used -it at work and at home repeatedly but not exclusively as I do now at -home since 2006.</p> - -<p><strong>How did you get in contact with the Skolelinux/Debian Edu -project?</strong></p> - -<p>Once a day in the early year of 2001 when I wanted to fetch my -daughter from primary school, there was a teacher sitting in the -middle of 20 old computers trying to boot them and he failed. I helped -him to get them booting. That was seen by the school director and she -asked me if I would like to manage that the school gets all that old -computers in use. I answered: "Yes".</p> - -<p>Some weeks later every of the 10 classrooms had one computer -running Windows98. I began to collect old computers and equipment as -gifts and installed the first computer room with a peer-to-peer -network. I did my work at school without being payed in my spare time -and with a lot of fun. About one year later the school was connected -to Internet and a local area network was installed in the school -building. That was the time to have a server and I knew it must be a -Linux server to be able to fulfil all the wishes of the teachers and -being able to do this in a transparent and economic way, without extra -costs for things like licence and software. So I searched for a -school server system running under Linux and I found a couple of -people nearby who founded 'skolelinux.de'. It was the Skolelinux -prerelease 32 I first tried out for being used at the school. I -managed the IT of that school until the municipal authority took over -the IT management and centralised the services for all schools in -Bielefeld in December of 2006.</p> - -<p><strong>What do you see as the advantages of Skolelinux/Debian -Edu?</strong></p> - -<p>When I'm looking back to the beginning, there were other advantages -for me as today.</p> - -<p>In the past there were advantages like:</p> - -<p><ul> - -<li>I don't need to buy it so it generates no costs to the school as -they had little money to spent for computers and software.</li> - -<li>It has a licence which grands all rights to use it without -cost.</li> - -<li>It was more able to fit all requirements of a server system for -schools than a Microsoft server system, even if there are only Windows -clients because of it's preconfigured overall concept of being a -infrastructure solution and community for schools, not only a -server</li> - -<li>I was able to configure the server to the needs of the -school.</li> - -</ul></p> - -<p>Today some of the advantages has been lost, changed or new ones -came up in this way:</p> - -<p><ul> - -<li>Most schools here do have money to buy hardware and software -now.</li> - -<li>They are today mostly managed from central IT departments which -have own concepts which often do not fit to Debian Edu concepts -because they are to close to Microsoft ideology.</li> - -<li>With the Squeeze version of Debian Edu which now uses GOsa² for -management I feel more able to manage the daily tasks than with the -interfaces used in the past.</li> - -<li>It is more modular than in the past and fits even better to the -different needs.</li> - -<li>The documentation is usable and gets better every day.</li> - -<li>More people than ever before are using Debian Edu all over the -world and so the community, which is an very important part I think, -is sharing knowledge and minds.</li> - -<li>Most, maybe all, of the technical requirements for schools are -solved today by Debian Edu. </li> - -</ul></p> - -<p><strong>What do you see as the disadvantages of Skolelinux/Debian -Edu?</strong></p> - -<p><ul> - -<li>There are too few IT companies able to integrate Debian Edu into -their product portfolio for serving schools with concepts or even -whole municipality areas.</li> - -<li>Debian Edu has beside other free and open software projects not -enough lobbyists which promote free and open software to -politicians.</li> - -<li>Technically there are no disadvantages I'm aware of.</li> - -</ul></p> - -<p><strong>Which free software do you use daily?</strong></p> - -<p>I use Debian stable on my home server and on my little desktop -computer. On my laptop I use Debian testing/sid. The applications I -use on my laptop and my desktop are Open/Libre-office, Iceweasel, -KMail, DigiKam, Amarok, Dolphin, okular and all the other programs I -need from the KDE environment. On console I use newsbeuter, mutt, -screen, irssi and all the other famous and useful tools.</p> - -<p>My home server provides mail services with exim, dovecot, roundcube -and mutt over ssh on the console, file services with samba, NFS, -rsync, web services with apache, moinmoin-wiki, multimedia services -with gallery2 and mediatomb and database services with MySQL for me -and the whole family. I probably forgot something.</p> - -<p><strong>Which strategy do you believe is the right one to use to -get schools to use free software?</strong></p> - -<p>I believe, we should provide concepts for IT companies to integrate -Debian Edu into their product portfolio with use cases for different -countries and areas all over the world.</p> - - -
