ITR 3 Introduction Thomas Krichel 2002-09-03 About me • Born 1965, in Völklingen (Germany) • Studied economics and social sciences at the Universities of Toulouse, Paris, Exeter and Leiceister. • PhD in theoretical macroeconomics • Lecturer in Economics at the University of Surrey 1993 and 2001 • Since 2001 assistant professor at the Palmer School Why • During research assistantship period, (1990 to 1993) I was constantly frustrated with difficult access to scientific literature. • At the same time, I discovered easy access to freely downloadable software over the Internet. • I decided to work towards downloadable scientific documents. This lead to my library career (eventually). Steps taken I • 1993 founded the NetEc project at http://netec.mcc.ac.uk, later available at http://netec.ier.hit-u.ac.jp as well as at http://netec.wustl.edu. • These are networking projects targetted to the economics community. The bulk is – Information about working papers – Downloadable working papers – Journal articles were added later Steps taken II • Set up RePEc, a digital library for economics research. Catalogs – Research documents – Collections of research documents – Researchers themselves – Organizations that are important to the research process • Decentralized collection, model for the open archives initiative Steps taken III • Co-founder of Open Archives Initiative • Work on the Academic Metadata Format • Current interests – Collaborative gathering of academic databases – Incentive mechanisms to provide free bibliographic data – Social issues surrounding free online scholarship ITR3 • Homepage to be built at http://wotan.liu.edu/home/krichel/itr3p01a • work plan to be decided upon today. I will first set out what has traditionally been covered. • And of course I have some innovative ideas. Why study IT? • Make better use of the tools • Self-help when there a problems • Reduce dependency on computer professionals • Conceptual challenge • Point and click is not sufficient • Stepping stone to more advanced stages of information processing, e.g. programming Maurer (undated) • Introduction • Logic and numbering system • Software • Architecture (3) • Video, Peripherals • Dismantle PC • Communication • LAN, WAN, Internet • Multimedia & graphics • Site visit, survey glossary • Project presentations • Final exam Hunter (1999) • • • • • • • • • • Introduction to class Overview of computers Bits and bytes Components Architecture (2) Data storage Storage media Memory Input devices Displays • • • • • • • • • • Printers Input/output Operating systems Multimedia Simulation and VR Laptops Communications Networks Internet (2) Issues: ethics, privacy Thomas thinks • • • • Hardware vs software Emerging technologies such as XML Isolated PC vs networked PC Using PC as an individual tool vs provision of public services • Learning from books vs learning by doing and/or from Internet sources. • Closed source vs open source software Software teaching • Teaching of proprietary software is bad. • Teaching of free user-level software is bad. • But that leaves the whole are of system administration in non-proprietary software environments. • Installing free software is not trivial. • Example: how to run a web server The networked PC • Teaching networks in this course is bad. • But the computer really becomes interesting as an information rather than a data processing tool once it is networked. • It is interesting to look at PCs in the way they handle networks. Unfortunately this is operating system dependent. Debian to the rescue • Debian is a free operating system. • It contains over 9000 packages. Each package is a software tool. Impossible to learn completely. • Information about it is mainly on the Internet. • It can use the linux kernel. • It is difficult to install. • It is easy to update. Debian installation to supplement traditional course • Students will learn more about system administration. This is more important than hardware. On a free operating system, we can justify covering it. • Learning by doing gets across some important concepts used in the software. • Linux and X11 can have a bad time working with hardware. Hardware knowledge can be applied there. Practical problems • Computers are available. • Network cards on these computers may be problematic. • Debian initial installation is best done in a big chunk of time. Once the computers are up, they can be used over the network. – If they are at school, we have a firewall and address problem. – If they are at home, we have a address problem and need to know about home networking. • Assignment could cover exploring the capabilities of particular software pieces.
