How to Improve the Web Information 
          Space? 
         Miroslav Milinović, University Computing Centre, Croatia
        Abstract
          The Internet information space is extremely broad, complex and rich 
          in diverse contents, but, at the same time, inadequately organised. 
          Web information sources are characterised by contents distribution and 
          dynamics, therefore managing the Internet information space is not easy. 
          Since the Internet information space is based on the Web, this presentation 
          will deal exactly with web technologies and their practical implementation. 
          It will look into the extent to which the development of the omnipresent 
          Web and its accompanying technologies has contributed to the quality 
          of the information space, and the ways to use new technologies in day-to-day 
          work.

         IT Armageddon: Seconds from Disaster
        Ivica Ostojić, CISCO, Croatia
        Abstract
          The evolution of the world wide communications and the Internet began 
          in the 1960's, but their real expansion took place as late as the early 
          90's. The Internet became an indispensable tool, both in private and 
          in business life. We are not aware of the fact that all of our activities 
          are based upon specific data and information. Data in correlation with 
          other data constitute a piece of information. The Internet is an infinite 
          source of data and information. Therefore, whether we are ready or not, 
          the Internet is becoming a part of our lives.
          However, nothing in the world is black or white. The Internet has two 
          sides. Today, security and privacy on the Internet represent a serious 
          problem, one which people do not take seriously enough. The fact that 
          computers are increasingly taking over more and more control over the 
          life processes of people does not make things any better. Network security 
          today is one of the biggest problems of the Internet, perhaps even the 
          greatest one. Every day we witness the newspaper articles and television 
          reports on security problems in the world of computers that have led 
          to financial losses, disclosure of classified information, etc.
          Therefore, this presentation will show methods of computer systems attacks 
          and defence, with special emphasis on e-commerce, illustration of the 
          classic attacker profile, the condition in the Republic of Croatia, 
          and the methods of defence from such attacks.

        GÉANT2: Latest developments and its importance for the 
Croatian research and education community
        Dai Davies, DANTE, United Kingdom
        Abstract
          The world of research networking has developed dramatically in the last 
          20 years. Initially it was a field exclusively for network technician 
          specialists. In those days you had to have a sound knowledge of operating 
          systems and packet switching to get in the act.
          Internet technology changed this picture significantly. For the first 
          time connectivity became available to ordinary users. In the absence 
          of any service a networking service that provides connectivity is bound 
          to be seen as innovative. The reality was, however, that performance 
          was always, and to some extent remains, a weakness.
        The liberalisation of telecommunications markets in Europe, including 
          Croatia, has enabled very large amounts of network capacity to be provided. 
          This, to some extent, helps deal with performance issues. The reality 
          however is that performance has today most users of research networks 
          at the level where research networking was twenty years ago. Unless 
          you are a network engineer or an operating systems specialist it is 
          inaccessible.
        GÉANT2 is part of an attempt to change this situation. It places much 
          more emphasis on delivering end-to-end services to users and on providing 
          users with tools to monitor what is provided on their behalf. The same 
          challenges apply to all European countries and undoubtedly users of 
          CARNET and the management of CARNET find themselves confronted with 
          the same issues.
        The main issue facing research networking in the next two years is 
          to focus on service rather than technology. The presentation will consider 
          the progress made in the context of GÉANT2 in terms of introducing services 
          and the obstacles research networking needs to overcome in order to 
          cater for an increasingly diverse and demanding user population. 
        Biography
          Dai Davies is one of the founder General Managers of DANTE, the pan-European 
          research and education (R&E) network organisation that was set up 
          in July 1993. DANTE’s primary mission is to plan, build and manage pan-European 
          research and education networks on behalf of Europe’s National research 
          and Education Networks (NRENs). Over the last decade DANTE has implemented 
          various pioneering generations of such network, always focussing on 
          advanced communications services. As a result Dai has considerable experience 
          of the translation between technology and service in a broad range of 
          communications activities. GÉANT2 represents the latest generation of 
          pan-European R&E network. Building on the achievements of its predecessor 
          networks, GÉANT2 once again breaks new ground for global research networking 
          with its innovative hybrid network solution. GÉANT2 sets new standards 
          in terms of technology, network capacity, service portfolio and international 
          connectivity.
          As research networking becomes a global activity, so DANTE becomes increasingly 
          involved in initiatives worldwide to build regional backbones and to 
          interconnect them to GÉANT2. DANTE is currently managing initiatives 
          focussed on the Mediterranean, Latin America and Asia-Pacifc regions 
          through the EUMEDCONNECT, ALICE and TEIN2 projects respectively. 
          Prior to DANTE, Dai was Director of the COSINE Project Management Unit 
          in Amsterdam. COSINE was a European project aimed at providing the academic 
          research community with telecommunications networking capabilities to 
          facilitate co-operative research. 
          In his earlier career Dai had worked for various European telecoms operators, 
          both in senior technical and commercial positions.
          Dai holds degrees in Engineering and Computer Science from Cambridge 
          University. 
        ICT in education – lessons from 
          the past, challanges for the future
        Hamish Macleod, University of Edinburgh, United Kingdom
        Abstract
          Technologies not only provide us with new ways of doing things, but 
          also give us new things to do, and reasons to do things differently. 
          McLuhan observed that first we shape our technologies, and then our 
          technologies shape us. When applied in the field of education, technologies 
          may be used to support traditional practices, or to transform our practices 
          and provide us with new and engaging opportunities for exploratory and 
          experiential learning. Even the most radical and transformative applications 
          of educational technology however, need to be developed in continuity 
          with our long established, and continually emerging, understandings 
          of the nature of human learning and knowledge construction. There is 
          a danger that preoccupation with the potential of the new can seduce 
          us into educational practices simply because the technology makes them 
          possible, rather than because they are grounded in a good understanding 
          of human psychology. Powerful motivators for learning come from curiosity, 
          and from human relationship and social communication. Through the power 
          of large databases, high speed networks, and sophisticated simulations 
          of real and virtual worlds, technology can provide us with rich and 
          engaging environments for exploratory and collaborative learning. And 
          such systems are not exclusively the province of large educational institutions 
          or government departments, but are part of the everyday experience of 
          even the youngest schoolchildren. This paper will review some of the 
          ways in which these technologies can provide powerful and motivating 
          environments for learning.
