Open Source CMSes are the latest rage it seems, and we've tried out dozens. One that stands out above the rest for small businesses and personal networks is the Elgg open source "social engine," which can be used to create social applications. In this article we'll take you through the installation of Elgg, and show you how to get started with this social networking CMS.

In this short essay, written for a symposium in the San Diego Law Review, Professor Daniel Solove examines the nothing to hide argument. When asked about government surveillance and data mining, many people respond by declaring: "I've got nothing to hide." According to the nothing to hide argument, there is no threat to privacy unless the government uncovers unlawful activity, in which case a person has no legitimate justification to claim that it remain private. The nothing to hide argument and its variants are quite prevalent, and thus are worth addressing. In this essay, Solove critiques the nothing to hide argument and exposes its faulty underpinnings.

Even though it has been used pervasively in datacenters for the past few years, virtualization isn't standing still. Rather, the technology is still evolving, and with the launch of I/O virtualization support from Intel and AMD it's poised to reach new levels of performance and flexibility. Our past virtualization coverage looked at the basics of what virtualization is, and how processors are virtualized. The current installment will take a close look at how I/O virtualization is used to boost the performance of individual servers by better virtualizing parts of the machine besides the CPU.

With some islands just big enough to stand on and others nearly as large as the center of Stockholm, the archipelago was once a rough and remote home to farmers and fishermen. Long an inspiration to Swedish artists and writers, the area changed in the middle of the last century, when tens of thousands of ordinary Swedes began to summer here. Now, as expensive year-round homes replace seasonal shacks, Stockholmers are discovering the area's off-season pleasures and property values are skyrocketing.

We asked the experts when they estimated AI would reach each of four milestones:

* passing the Turing test by carrying on a conversation well enough to pass as a human * solving problems as well as a third grade elementary school student * performing Nobel-quality scientific work * going beyond the human level to superhuman intelligence

We also asked how the timing of achieving these milestones would be affected by massive funding of $100 billion/year going into AGI R&D.

We also probed opinions on what the really intelligent AIs will look like — will they have physical bodies or will they just live in the computer and communicate with voice or text? And how can we get from here to there?

Thus in every land where Christianity spread the slain and resurrected god, and the dramatic annual celebration of his death and resurrection, were quite familiar. It was Tammuz all over the plains of Mesopotamia, from Ur of the Chaldees to Jerusalem. It was Attis all over the region to the north and northwest of Palestine and through the old Phoenician civilization on the coast of Palestine and Asia Minor. It was Adonis in Greece, then in Rome, and gradually all over the Greco-Roman world.

"I am the Resurrection and the Life" is merely an epitome of what the Egyptians chanted for ages about their great god Osiris, the judge of the dead, one of the oldest and most revered gods of Egypt. He had been slain by "the powers of darkness" embodied in his wicked brother, Set. His sister and wife, Isis, had sought the fragments of his body and put them together again. And he had arisen from the dead, and was enthroned in the world of souls, to judge every man according to his works.

jQuery doesn't focus on things outside of the DOM. This is one of the reasons it is so easy to learn, but it also limits the ways it can help you write JavaScript. It's just not trying to be anything other than a solid programming system for the DOM. It doesn't address inheritance nor does it address the basic utilities of all the native types in the JavaScript language, but it doesn't need to. [...]

This is where MooTools is vastly different. Rather than focusing exclusively on the DOM (though, as I'll get into in a bit, it offers all the functionality that jQuery does but accomplishes this in a very different manner), MooTools takes into its scope the entire language. If jQuery makes the DOM your playground, MooTools aims to make JavaScript your playground, and this is one of the reasons why it's harder to learn.

The ubiquity of frustrating, unhelpful software interfaces has motivated decades of research into “Human-Computer Interaction.” In this paper, I suggest that the long-standing focus on “interaction” may be misguided. For a majority subset of software, called “information software,” I argue that interactivity is actually a curse for users and a crutch for designers, and users’ goals can be better satisfied through other means.

Using just open source tools and a few tweaks, it is possible to detect and block suspicious login attempts.

[W]e describe selected studies of experimental evolution with robots to illustrate how the process of natural selection can lead to the evolution of complex traits such as adaptive behaviours. Just a few hundred generations of selection are sufficient to allow robots to evolve collision-free movement, homing, sophisticated predator versus prey strategies, coadaptation of brains and bodies, cooperation, and even altruism. In all cases this occurred via selection in robots controlled by a simple neural network, which mutated randomly.
