To highlight a body of text, select the text and click Diigo on the toolbar or in the right-click menu. If this page has not been previously bookmarked yet, the system will ask you to bookmark first, so that both the highlight and this page will be bookmarked simultaneously. For any page already bookmarked, highlight will show up instantaneously when you click Diigo. A highlight is only viewable to its owner on the original page, and is NOT viewable to the public on the original page unless there are public Sticky Notes associated with it. (This is designed to reduce graffiti on the original webpage) On the Diigo website, all highlights will be shown as clippings along with the bookmarks.  If a bookmark is public, so will be its associated clippings. (This is designed to maximize information sharing) Use the floating menu over highlight to delete it or to add sticky notes. If the floating menu is disabled (in Options), simply left-click it to add sticky, and right-click to delete it.

The e-commerce leader, with its swooning stock price and recent management shakeup, said last week that it is shifting its focus away from its historic auction model to the sale of fixed price goods. But as the economy craters, consumers will certainly go looking for deep discounts and good values.

The semantic web is an evolving extension of the World Wide Web in which web content can be expressed not only in natural language, but also in a format that can be read and used by software agents, thus permitting them to find, share and integrate information more easily.[1] It derives from W3C director Sir Tim Berners-Lee's vision of the Web as a universal medium for data, information, and knowledge exchange.

The Three Projections of Futamura are a sequence of applications of a programming technique called 'partial evaluation' or 'specialisation', each one more mind-bending than the previous one. But it shouldn't be programmers who have all the fun. So I'm going to try to explain the three projections in a way that non-programmers can maybe understand too.

Programming DNA A 2-bit language for engineering biology Biological engineering does not have to be confined to the laboratories of high-end industry laboratories. Rather, it is desirable to foster a more open culture of biological technology. This talk is an effort to do so; it aims to equip you with basic practical knowledge of biological engineering.

Productivity Keep track of your time with the Emergent Task Tracker, online edition Designer David Seah's previously mentioned Emergent Task Planner, which we featured as a downloadable PDF, is now available (with a few small tweaks) in a web-based Flash application called the Emergent Task Timer. The idea: type in your pressing to-dos for the day, then fill in a circle for every 15 minutes you spend on each task. At the end of the day, you can print it out to keep an eye on what you've been doing. The Emergent Task Timer will chime every 15 minutes to remind you to fill in a circle, so you've got no excuse not to keep it updated. Not only is this a terrific tool for tracking your time, but it's also a smart way to keep focused on productive endeavors. Thanks Tim!

UbuWeb is pleased to present dozens of avant-garde films & videos for your viewing pleasure. However, it is important to us that you realize that what you will see is in no way comparable to the experience of seeing these gems as they were intended to be seen: in a dark room, on a large screen, with a good sound system and, most importantly, with a roomful of warm, like-minded bodies.

Nine super powers made real by modern technology. Advances in bionics, transportation, and other technologies have put comic book superheroes a little closer to reality. This collection of videos looks at a few ways we can achieve “super powers”. Link -via Reddit

The Web Ontology Language (OWL) is a language for defining and instantiating Web ontologies.[1] An OWL ontology may include descriptions of classes, along with their related properties and instances. OWL is designed for use by applications that need to process the content of information instead of just presenting information to humans. It facilitates greater machine interpretability of Web content than that supported by XML, RDF, and RDF Schema (RDF-S) by providing additional vocabulary along with a formal semantics. OWL is based on earlier languages OIL and DAML+OIL, and is now a W3C recommendation.

As Lifehacker describes it, ReadBurner, "turn[s] Google Reader sharing into an action similar to bookmarking a page on Del.icio.us or voting for an article on Digg."

Spontaneous human combustion (SHC) refers to the belief that the human body sometimes burns without an external source of ignition. There is much speculation and controversy regarding SHC, for it is not a proven natural phenomenon. Many theories and hypotheses have attempted to explain how SHC might occur, but those which rely on current scientific understanding say that instances mistaken for spontaneous combustion actually required a source of ignition. One such hypothesis is the "wick effect", in which the clothing of the victim soaks up melted human fat and acts like the wick of a candle. Another possibility is that the clothing is caused to burn by a discharge of static electricity. The likelihood that truly spontaneous human combustion actually takes place is remote, due to the presence of water and the lack of highly flammable compounds and oxygen in the human body.[1]
