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.

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.

At its core, the semantic web is comprised of a philosophy,[2] a set of design principles,[3] collaborative working groups, and a variety of enabling technologies.

"Form follows computation" captures a present phenomenon: Methodical overspill of programming is giving rise to a distinct aesthetic sensibility.

Meaning shifts as connotations change over time and reading becomes an act of writing if the connotations are purposefully reformulated. Accordingly, deducing meaning from the author's intention is an intentional fallacy [Wimsatt, Beardsley]. Followed to the extreme, context is everything.

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.
