Drzach & Suchy: shadow cloud A shadow cloud is a three-dimensional object, consisting of multiple shadow-casting elements semi-randomly arranged in three dimensions in such a way, that depending on the direction of illumination the overall shadow of the cloud displays various images encoded in it. A shadow cloud can be viewed as a generalization of shadow casting panels, but of course the basic idea of multiple shadows from one three-dimensional structure is already present in well-known GEB-triples. However, in contrast to GEB-triplets, a shadow cloud can encode up to four arbitrary images and display them under appropriate illumination without any distortions. The idea of shadow clouds can be summarized as follows: the shadow cast by flat, thin elements depends on their relation to the direction of illumination: elements perpendicular to illumination cast clear shadows, while the shadows of elements parallel to illumination are practically invisible.

Mark Zuckerberg is TIME Magazine's Person of the Year? Where's the "dislike" button? As for Person of the Year, we couldn't find the dislike button on Facebook for TIME's choice, so we made our own. Here's our version of the magazine: Unfortunately, the terms under which he claims to have done this set a terrible precedent for our future — for our control over the software we use to interact with each other, for control over our data, and for our privacy. The damage is not limited to Facebook users. This much is evident from Facebook's outward behavior — but things could actually be much worse than we know. Fortunately, there are many efforts underway to provide distributed, user-controlled services to facilitate connection between people, including GNU social, status.net, Crabgrass, Appleseed and Diaspora. These efforts will eventually succeed. Copy and paste this code for your own website! Our button, of course, is not linked to any surveillance database or tracking system.

The Right to Read by Richard Stallman Join our mailing list about the dangers of eBooks. This article appeared in the February 1997 issue of Communications of the ACM (Volume 40, Number 2). From The Road To Tycho, a collection of articles about the antecedents of the Lunarian Revolution, published in Luna City in 2096. For Dan Halbert, the road to Tycho began in college—when Lissa Lenz asked to borrow his computer. This put Dan in a dilemma. And there wasn't much chance that the SPA—the Software Protection Authority—would fail to catch him. Of course, Lissa did not necessarily intend to read his books. Later on, Dan would learn there was a time when anyone could go to the library and read journal articles, and even books, without having to pay. There were ways, of course, to get around the SPA and Central Licensing. Dan would later learn that there was a time when anyone could have debugging tools. It was also possible to bypass the copyright monitors by installing a modified system kernel. Author's Note
