Marvel teased us with the release of this film near the end of various previously released super hero flicks like Captain America and Iron Man 2. This would be the movie that unites all the super heroes from the Marvel universe. Well actually, only those that had not been previously licensed to other studios. Hence, you will not find characters from X-Men, Spiderman, or the Fantastic Four in this movie. Director Joss Whedon brings back fond memories of creative television series like Firefly and Dollhouse, but what does he make of a 220 million blockbuster production?

Hugo

Almer S. Tigelaar 06 / 03 / 2012

Hugo is based on a relatively recently released (2007) award winning book by Brian Selznick. It is not surprising that the film rights to the books were quickly sold, and certainly not by the least of directors either: Martin Scorsese. He has a career spanning decades and has directed a string of movies in recent years which I liked, among which are Shutter Island, The Departed and Gangs of New York. However, those were admittedly all in different, less family friendly, genres. So, I went to Hugo hoping to be pleasantly surprised.

How long would it take to read Wikipedia?

Wikipedia has become the de facto encyclopedia on the Internet. A traditional encyclopedia spans many textbook volumes which would take any normal person ages to read. Few people would likely engage in such an endeavor. However, since Wikipedia is readily accessible: should you take up the challenge?

Abstract
Many servers on the web offer content that is only accessible via a search interface. These are part of the deep web. Using conventional crawling to index the content of these remote servers is impossible without some form of cooperation. Query-based sampling provides an alternative to crawling requiring no cooperation beyond a basic search interface. In this approach, conventionally, random queries are sent to a server to obtain a sample of documents of the underlying collection. The sample represents the entire server content. This representation is called a resource description. In this research we explore if better resource descriptions can be obtained by using alternative query construction strategies. The results indicate that randomly choosing queries from the vocabulary of sampled documents is indeed a good strategy. However, we show that, when sampling a large collection, using the least frequent terms in the sample yields a better resource description than using randomly chosen terms.
