Data Wrangler
UPDATE: The Stanford/Berkeley Wrangler research project is complete, and the software is no longer actively supported. Instead, we have started a commercial venture, Trifacta. For the most recent version of the tool, see the free Trifacta Wrangler. Why wrangle?

Half a Million DVDs of Data Stored in Gram of DNA | Wired Science By Robert F. Service, ScienceNOW Paleontologists routinely resurrect and sequence DNA from woolly mammoths and other long-extinct species. Future paleontologists, or librarians, may do much the same to pull up Shakespeare’s sonnets, listen to Martin Luther King Jr.’s “I have a dream” speech, or view photos. Researchers in the United Kingdom report today that they’ve encoded these works and others in DNA and later sequenced the genetic material to reconstruct the written, audio, and visual information. The new work isn’t the first example of large-scale storage of digital information in DNA. To do so, the team first translated written words or other data into a standard binary code of 0s and 1s, and then converted this to a trinary code of 0s, 1s, and 2s—a step needed to help prevent the introduction of errors. Beyond demonstrating DNA’s superlative information storage abilities, Goldman, Birney, and their colleagues also asked when such a technology might be worth implementing.

"TPB : AFK", The Pirate Bay sous les projecteurs Le Monde.fr | • Mis à jour le | Par Damien Leloup Six lettres et 80 minutes pour décrire le plus grand procès de téléchargement illégal des dix dernières années : TPB : AFK (The Pirate Bay : Away from Keyboard) est un documentaire ambitieux - et parfois déroutant. Ambitieux, parce qu'il suit, sur plusieurs années, les différentes étapes du processus judiciaire qui a abouti à la condamnation de plusieurs fondateurs de The Pirate Bay, le plus grand annuaire de liens de téléchargement BitTorrent au monde. Déroutant, parce que la succession de scènes souvent surréalistes saisies par les caméras du réalisateur Simon Klose jette un éclairage cru sur les créateurs du site. Depuis le 10 février, le documentaire, cofinancé par des dons et par plusieurs chaînes de télévision dont Arte, est diffusé gratuitement sur Internet. Sur The Pirate Bay, bien sûr, où il peut être téléchargé légalement, mais aussi sur YouTube, où il a déjà été visionné plus d'1,3 millions de fois.

Is Your Website Ready For the Coming Tablet Explosion? If the vast majority of analysts and pundits are to be believed, 2011 will be the year of the tablet, and the popular adoption of the devices won't stop there. In a recent report, Forrester predicted that tablet sales could quadruple from 2010 to 2015, leading to a surge in tablet-based e-commerce and chipping away at the amount of Web traffic coming from PC's. Many site owners are already seeing a huge uptick in users browsing from tablets, and that upward trend will continue. Is your company's Website ready for these visitors? Test Your Site on a Tablet Using your own site on a tablet computer is the only way to get an accurate idea of what other users experience when they browse your site from such a device. Don't own an iPad or another tablet computer yet? If you're desperate, you could even download Apple's iOS SDK, which comes with a desktop iPad simulator. Simplify the Layout Even if your desktop site's design renders properly on tablets, that doesn't mean the battle is won.

Ronald Dworkin obituary | Law Ronald Dworkin, who has died aged 81, was widely respected as the most original and powerful philosopher of law in the English-speaking world. In his books, his articles and his teaching, in London and New York, he developed a powerful, scholarly exegesis of the law, and expounded issues of burning topicality and public concern – including how the law should deal with race, abortion, euthanasia and equality – in ways that were accessible to lay readers. His legal arguments were subtly presented applications to specific problems of a classic liberal philosophy which, in turn, was grounded in his belief that law must take its authority from what ordinary people would recognise as moral virtue. Dworkin studied philosophy (under Willard Van Orman Quine at Harvard University and, informally, with JL Austin at Oxford University) and law at both Oxford and the Harvard Law School. Dworkin was born in Worcester, Massachusetts. His books were immensely influential, especially in US law schools.
