The thin client solution we currently have running in Mekelle is based on using OpenSolaris and we have a variety of terminals – a mixture of SunRay 1′s, SunRay 2′s and Nortech clients. Using sun ray session server, the sunray terminals are performing well, but when we have the labs full of students, the Nortech terminals are significantly less responsive. There are a number of possible reasons for this, the protocols used, the network amongst others. There is a huge range of other configurations and technologies we could use to provide a robust and scalable thin client architecture.
I’ve spent a few days this week in Barcelona with Cast-Info investigating their Desktop4All solution, which we’re looking to trial as an alternative to the OpenSolaris setup we currently have. Goitom, one of the phds students from Mekelle will spend the next few weeks based in the Cast-Info offices, learning how to install and set up the server system used for Desktop4All, with a view to installing this when back in Mekelle in a couple of months.
Desktop4All, based on Linux, is a set of integrated open source applications. It’s likely to produce a similar end result to the solution that we already have running with OpenSolaris, but the main advantage for us will be in the support and documentation available as a reference. Testing out Desktop4All will give us the opportunity to collaborate in the development and to investigate whether we get similar types of issues arising as we have had with OpenSolaris.
When we started the Digital Campus project, I think there was some concern over whether the students would need much training in how to use a non-Windows operating system, given that much (all?) of their previous experience of using computers/pcs was with Windows (usually XP). This has turned out not to be the case, given that many students have had limited time to become locked in Windows, we’ve found few issues with students being unable to navigate the interface or use applications. I suspect we don’t always give the students credit for their ability to adapt to new interfaces and systems (especially judging by how quickly they find their way to webmail, youtube and facebook).
