The Horto Domi combines vermiculture, geodesic domes, moisture sensors, and Arduino open hardware controllers in an automated backyard food growing system for the everyperson. The project team is looking for supporters on Kickstarter so they can do more R&D and make the plans available to the public for free. Soon you could have a pod of robotic food growing domes in your backyard turning out bushels of fresh veg. Then again, maybe a food growing robot takes the joy out of growing your own?

Justin Nichol sez, "Black Flag Games is currently running a Kickstarter to produce a radical boardgame project called 'A Las Barricadas'. It is a boardgame about conflict between state police and anti-authoritarian demonstrators. It is a two-player game with each player representing one of these social forces. The theatre of the conflict is street demonstration. It has been designed to inspire tactical consideration and conversation and is being developed and designed by the Black Flag Games Collective, committed to the idea that games and interactive media can have an impact in the struggle for a free and cooperative world. We are also committed to the ideals of free culture and aim to deliver professional play experiences that enrich a participatory entertainment culture."

A lot of times I have people asking me about interfacing a fingerprint sensor to an arduino for their school projects.

Inside NYU art professor David Darts' black metal lunchbox, painted with a white skull and crossbones, is the PirateBox - a tiny Linux server, a wireless router, and a battery. Turn the PirateBox on and you have a self-contained mobile communications and file-sharing device, whereby those in the vicinity can upload and download files securely and anonymously. (See this 2011 Ars Technica story for photos and details.) Built with free and open source software and openly licensed itself, the PirateBox has inspired a number of other projects, including Alan Levine's Storybox and now Jason Griffey's LibraryBox.

AN FRANCISCO -- The first Project Glass products -- Google's network-enabled, computerized glasses -- are set to ship to a select group of enthusiasts early next year, co-founder Sergey Brin said today. "This is not a consumer device," Brin told thousands in an enthusiastically cheering audience at the company's Google I/O show today here. "You have to want to be on the bleeding edge. That's what this is designed for." The glasses will be available only to Google I/O attendees who are in the United States. The geographic restriction is for regulatory reasons, Brin said. (Different countries have different requirements for radio-frequency emissions.)

Reproducibility is a key part of science, even though almost nobody does the same experiment twice. A lab will generally repeat an experiment several times and look for results before they get published. But, once that paper is published, people tend to look for reproducibility in other ways, testing the consequences of a finding, extending it to new contexts or different populations. Almost nobody goes back and repeats something that's already been published, though. But maybe they should. At least that's the thinking behind a new effort called the Reproducibility Initiative, a project hosted by the Science Exchange and supported by Nature, PLoS, and the Rockefeller University Press.

So, after my post on ground-truth documents, one of my commenters argued eloquently that I ought to clean it up and submit it to a journal read by people who manage programming projects. He suggested Software Practice and Experience. This seemed like a pretty good idea, until I read SP&E's submission procedures and was reminded that (like most journals) they want me to assign the copyright of my submission to the publisher. My instant reaction was this: Fuck. That. Noise. I'm certainly willing to cede publication rights when I want to be published, but copyright assignment ain't going to happen. Ever. Nobody gets to own my work but me. (Yes, I insist on this with my book publishers too.) I have a message to all you technical journal publishers out there…

The last time we ran into Ben Heck, the tinkerer extraordinaire was waxing poetic at Maker Faire about the Raspberry Pi and cheese curds. One more thing he also talked about, however, was his latest 3D printer project, which he now explains in greater detail in the latest episode of the Ben Heck Show. Improvements made to the device include use of a Birdstruder for easier access to the filament and the ability to print off an SD card if you don't have a computer handy. The 3D printer also sports an expanded 200-square-millimeter print area with a solid copper cover for added sturdiness and accuracy. As usual, size matters for Mr. Heckendorn so the device got a boost in portability, now neatly folding James Bond-like into a briefcase that measures 18 x 14 x 4.2 inches. Interested in a briefcase printer of your own? Well, Heckendorn mentioned during the Maker Faire interview that he's already working on an improved version and thinking about putting it up on Kickstarter so hope springs eternal. In the meantime, you can glean more details about the device by checking out the video after the break.

On Project Gutenberg, the 1811 edition of Francis Grose's "Dictionary in the Vulgar Tongue," a compleat look at all the dirty cussin' of the early 1800s. It was produced by Juliet Sutherland, Charles Franks and the Online Distributed Proofreading Team, who clearly have admirably filthy minds. Some of my favorites:

People who constantly reach into a pocket to check a smartphone for bits of information will soon have another option: a pair of Google-made glasses that will be able to stream information to the wearer's eyeballs in real time. According to several Google employees familiar with the project who asked not to be named, the glasses will go on sale to the public by the end of the year. These people said they are expected "to cost around the price of current smartphones," or $250 to $600.

Joey Hudy, a young "maker" from Phoenix went to the White House this week to show off his project, the "Extreme Marshmallow Cannon." When President Obama saw it, he told Joey: "Let's try it." Joey set up the air cannon, which uses a bicycle pump to build up air pressure, and put a marshmallow down the barrel. When he pressed the trigger, a single marshmallow was shot out across the room to the delight of everyone, but especially the president.

Facebook and Google are two of technology's great data projects. Love them or hate them, they spend all day mining their users' activity. They harvest a few dozen bits of usable personal information per user per day. All in the interest of serving you ads.

Last week, the Iranian government apparently started a new censorship program that blocks encrypted Internet traffic. Even Iranians who had taken steps to evade government firewalls were being stymied-and the immediate impact can be seen in usage of the Tor network.

The Open Knowledge Foundation (OKF) announced the 1.0 release of the Open Data Handbook today. The 1.0 release is the culmination of a project that started in October 2010 at a book sprint in Berlin as the Open Data Manual.

"The Open Data Institute (ODI) officially opens this week and it is "a collaboration between businesses, entrepreneurs, researchers, government and society to unlock enterprise and social value from the vast amount of open government data now being made available". That's quite a mouthful - put plainly, there's a truck load of open data around, so let's have at it and see what we can do."

It's been the case for every SQL database in practical use since E. F. Codd first came up with the concept: Records either exist or they don't. When you run a SELECT statement, you're querying the current state of the data. A state is either true or false.

Developer kit for the Oculus Rift - the first truly immersive virtual reality headset for video games.

Seriously? You care enough about temporal accuracy buy an atomic clock but you don't know how to build one? We won't tell.Thankfully DIY Physics has a great tutorial on how to build your own with parts from eBay.

The Cryoscope shows the user exactly what to expect outside by haptically exhibiting exactly how cold or warm it is to be outside. The user simply touches an aluminum cube that has been heated or cooled to the appropriate temperature. The unit fetches weather data from the internet, and translates it to the cube physically, pumping heat in or out of the cube.
