Niklaus Wirth of the Swiss Federal Institute of Technology {ETH] waspresented the 1984 ACM A. M. Ihring Award at the Association’s Annual Conference in San Francisco in October in recognition of his outstanding work in developing a sequence of innovative computer languages: Euler’ ALGOL-W, Modula, and Pascal. Pascal, in particular, has become significant pedagogically and has established a foundation for future research in the areas of computer language, systems, and architecture. The hallmarks of a Wirth language are its simplicity, economy of design, and high-quality engineering, which result in a language whose notation appears to be a natural extension of algorithmic thinking rather than an extraneous formalism.

GNS3 is a Graphical Network Simulator that allows emulation of complex networks. You may be familiar with VMWare or Virtual PC that are used to emulate various operating systems in a virtual environment. These programs allow you to run operating systems such as Windows XP Professional or Ubuntu Linux in a virtual environment on your computer. GNS3 allows the same type of emulation using Cisco Internetwork Operating Systems. It allows you to run a Cisco IOS in a virtual environment on your computer. GNS3 is a graphical front end to a product called Dynagen. Dynamips is the core program that allows IOS emulation. Dynagen runs on top of Dynamips to create a more user friendly, text-based environment. A user may create network topologies using simple Windows ini-type files with Dynagen running on top of Dynamips. GNS3 takes this a step further by providing a graphical environment.

Tagging is an important way for users to succinctly describe the content they upload to the Internet. However, most tag-suggestion systems recommend words that are highly correlated with the existing tag set, and thus add little information to a user’s contribution. This paper describes a means to determine the ambiguity of a set of (user-contributed) tags and suggests new tags that disambiguate the original tags. We introduce a probabilistic framework that allows us to find two tags that appear in different contexts but are both likely to co-occur with the original tag set. If such tags can be found, the current description is considered “ambiguous” and the two tags are recommended to the user for further clarification. In contrast to previous work, we only query the user when information is most needed and good suggestions are available. We verify the efficacy of our approach using geographical, temporal and semantic metadata, and a user study. We built our system using statistics from a large (100M) database of images and their tags.

Today you can buy dozens and dozens of books about learning objects (LO). The subject seems to be mature enough to be used widely in learning and teaching practice. But after the initial hype less than ten years ago, things have not gone as smoothly as expected. Why? Predictions were promising: LO repositories will create a market for learning content, this will reduce costs for instructional design, shorten the development time for e-learning courses, different instructors will be able to use the same materials.
