Sir Francis Chichester, Robin Knox-Johnston, Dame Ellen McArthur and other great names from the history of sailing could be joined this year by Pinta the robot.

The unmanned boat is undergoing final preparations before setting sail in the hope of becoming the first robot to cross an ocean using the power of wind. By sailing non-stop and unassisted for an estimated three months it will prove the potential for robotic craft to undertake vital research in roles in dangerous and far-off waters.

Pinta has been designed by scientists at Aberystwyth University and will join seven other robotic craft in October in a race across the Atlantic. The race is intended to test the endurance and reliability of robots away from battery chargers and the predictable environment of a laboratory.

Pinta the robot sailing boat takes on Atlantic challenge

Millions of people around the world today spend portions of their lives in online virtual worlds. Second Life is one of the largest of these virtual worlds. The residents of Second Life create communities, buy property and build homes, go to concerts, meet in bars, attend weddings and religious services, buy and sell virtual goods and services, find friendship, fall in love--the possibilities are endless, and all encountered through a computer screen. Coming of Age in Second Life is the first book of anthropology to examine this thriving alternate universe.

Tom Boellstorff conducted more than two years of fieldwork in Second Life, living among and observing its residents in exactly the same way anthropologists traditionally have done to learn about cultures and social groups in the so-called real world. He conducted his research as the avatar "Tom Bukowski," and applied the rigorous methods of anthropology to study many facets of this new frontier of human life, including issues of gender, race, sex, money, conflict and antisocial behavior, the construction of place and time, and the interplay of self and group.

Coming of Age in Second Life shows how virtual worlds can change ideas about identity and society. Bringing anthropology into territory never before studied, this book demonstrates that in some ways humans have always been virtual, and that virtual worlds in all their rich complexity build upon a human capacity for culture that is as old as humanity itself.

Núcleo is a toolkit for exploring new uses of video and new human-computer interaction techniques.

People don’t like being told what to do. We like to explore, change things around, and make a place our own. Hefty design challenges await the makers of websites where people feel free to engage; both with the system itself and with each other. Embrace the idea that people will warp and stretch your site in ways you can’t predict—they’ll surprise you with their creativity and make something wonderful with what you provide.

At Flickr, we’ve worked very hard to remain neutral while our members jostle and collide and talk and whisper to each other. Sharing photos is practically a side-effect. Our members have thrilled and challenged us—not just with their beautiful photography, but by showing us how to use our infrastructure in ways we could have never imagined.

It’s only in hindsight and with analysis that the strategies I share in this article have emerged.

Community: From Little Things, Big Things Grow

Technology can be sublime, but machines aren’t something that happens to us; they’re something we make. That is, they’re less like meteors that come crashing into our planet (actually, “billiard balls” appears to be the preferred metaphor) than like toddlers (O.K., that one’s mine): sure, they crash into you a lot, and change your life, but they didn’t come out of nowhere and, if you set your mind to it, you can teach them manners before they get to be bigger than you. “The story of the power revolution offers more than an interpretation of the origins of industrial America,” Klein writes. “It suggests another insight into the most elusive riddle of all: What is an American?” Klein’s answer to the question Crèvecoeur famously asked in 1782—“What then is this American, this new man?—is disheartening, to say the least. He is a man whose machines run roughshod. I don’t know about you, but I’d take the toddler over the meteor every time. Setting limits. They say it’s all about setting limits.

With input from people around the world -- much of it on this website -- an international group of leading technological thinkers were asked to identify the Grand Challenges for Engineering in the 21st Century. Now their conclusions are revealed on this website.

Grand Challenges for Engineering

Creating a viable free open source alternative to
Magma, Maple, Mathematica, and Matlab

Jacob Seidelin went on a ( crazy :) ) mission to create a pure JavaScript video player that didn't use Flash:

My first thought was to read binary video files using a technique like the Andy Na posted about here, figuring that there must be some really simple to parse video formats around, but I soon changed directions and decided to make up a whole new video format. Enter.. JSONVid. Using a player like mplayer, it is easy to export all frames in a movie clip to individual jpeg files, and using whichever language you prefer it is also fairly trivial to collect these files, base64 encode the bunch of them and throw them all together in a nice JSON file (I used this PHP script).

Zorba is a general purpose XQuery processor implementing in C the W3C family of specifications. It is not an XML database. The query processor has been designed to be embeddable in a variety of environments such as other programming languages extended with XML processing capabilities, browsers, database servers, XML message dispatchers, or smartphones. Its architecture employes a modular design, which allows customizing the Zorba query processor to the environment’s needs. In particular the architecture of the query processor allows a pluggable XML store (e.g. main memory, DOM stores, persistent disk-based large stores, S3 stores). Zorba runs on most platforms and is available under the Apache license v2.
