This excerpt from neurologist-philosopher Daniel Dennett's new book Intuition Pumps And Other Tools for Thinking lays out a set of rhetorical habits that I immediately aspired to attain:
How to compose a successful critical commentary:
1. Attempt to re-express your target's position so clearly, vividly and fairly that your target says: "Thanks, I wish I'd thought of putting it that way."
2. List any points of agreement (especially if they are not matters of general or widespread agreement).
3. Mention anything you have learned from your target.
4. Only then are you permitted to say so much as a word of rebuttal or criticism.
And if that wasn't enough: "whenever you see a rhetorical question, try – silently, to yourself – to give it an unobvious answer. If you find a good one, surprise your interlocutor by answering the question." And then, "A good moral to draw from this observation is that when you want to criticise a field, a genre, a discipline, an art form …don't waste your time and ours hooting at the crap! Go after the good stuff or leave it alone."
A mechanical engineer (awesomely) named Anjan Contractor has won a NASA grant to prototype a 3D printer for food -- specifically pizza. It will lay down layers of food and flavor powder and melt them together; the powders are room-temperature stable for long periods and can be made from relatively abundant, sustainable foodstocks like insects and soylent green. He prototyped the concept with the 3D chocolate printer in the video above, and he holds out hope that food-printing could solve world hunger by allowing billions to feast on low-wastage, low-energy-input, low-carbon-footprint foods that are printed to order.
Contractor's printer is RepRap based, and is open source hardware; he promises to keep the plans open and free.
I suspect that there's a lot of nutritional subtleties lost when you turn food into processed elements that are recombined (in the same way that beta-carotene in carrots is reliably shown to have health benefits, while beta-carotene supplements are far more questionable). But as a form of food processing, it certainly is exciting!
Pizza is an obvious candidate for 3D printing because it can be printed in distinct layers, so it only requires the print head to extrude one substance at a time. Contractor’s “pizza printer” is still at the conceptual stage, and he will begin building it within two weeks. It works by first “printing” a layer of dough, which is baked at the same time it’s printed, by a heated plate at the bottom of the printer. Then it lays down a tomato base, “which is also stored in a powdered form, and then mixed with water and oil,” says Contractor.
Finally, the pizza is topped with the delicious-sounding “protein layer,” which could come from any source, including animals, milk or plants.
Danah boyd has a great summary of the new Pew report on Teens, Social Media, and Privacy. The whole thing is worth a read -- especially her thoughts on race and social media use -- but the most interesting stuff was about "social steganography" -- smuggling meaning past grown-ups through the clever use of in-jokes and obscure references (this is also something that Chinese net-users do to get past their national censors):
My favorite finding of Pew’s is that 58% of teens cloak their messages either through inside jokes or other obscure references, with more older teens (62%) engaging in this practice than younger teens (46%). This is the practice that I’ve seen significantly rise since I first started doing work on teens’ engagement with social media. It’s the source of what Alice Marwick and I describe as “social steganography” in our paper on teen privacy practices.
While adults are often anxious about shared data that might be used by government agencies, advertisers, or evil older men, teens are much more attentive to those who hold immediate power over them – parents, teachers, college admissions officers, army recruiters, etc. To adults, services like Facebook that may seem “private” because you can use privacy tools, but they don’t feel that way to youth who feel like their privacy is invaded on a daily basis. (This, btw, is part of why teens feel like Twitter is more intimate than Facebook. And why you see data like Pew’s that show that teens on Facebook have, on average 300 friends while, on Twitter, they have 79 friends.) Most teens aren’t worried about strangers; their worried about getting into trouble.
Over the last few years, I’ve watched as teens have given up on controlling access to content. It’s too hard, too frustrating, and technology simply can’t fix the power issues. Instead, what they’ve been doing is focusing on controlling access to meaning. A comment might look like it means one thing, when in fact it means something quite different. By cloaking their accessible content, teens reclaim power over those who they know who are surveilling them. This practice is still only really emerging en masse, so I was delighted that Pew could put numbers to it. I should note that, as Instagram grows, I’m seeing more and more of this. A picture of a donut may not be about a donut. While adults worry about how teens’ demographic data might be used, teens are becoming much more savvy at finding ways to encode their content and achieve privacy in public.
Zack sez, "Jack 'King of Comics' Kirby's grandson is looking to raise funds for a coffee-table-sized book that will look at Kirby's life and times...along with a never-before-seen play by the master of comics. The book will include a wide variety of unpublished personal photographs and artwork from Kirby dating through the 1980s."
You have to pledge at least $50 to get a copy of the book, which is a lot, though the book sounds rather spectacular. Kirby's grandson doesn't list any publishing experience in his bio and doesn't list any helpers experienced in printing, layout, QA, or fulfillment, so caveat emptor.
The suit alleges that West Sixth's own logo, which is a "6" within a circle, infringes upon its trademarked "#9" mark and is "directing Defendant West Sixth to account for and to pay over to Magic Hat all profits realized by West Sixth as a result of its use of the 6 Marks, its infringement of MagicHat's trademarks and trade dress, and its acts of unfair competition" as part of the awards it seeks from this suit.
Magic Hat is owned by North American Breweries, a large, multinational corporation that produces and imports several different brands of beer. West Sixth, on the other hand, is a local startup started about a year ago that strives to give back to its own community through financial donations, environmental stewardship, and community activities, many of which are free for attendees.
Margaret Killjoy sez, "Steampunk Magazine #9 is out and available for order. The pdf is up as well. New orders and pre-orders will be going out this weekend! 118 ad-free, Creative-Commons pages of steampunk mad science, lifestyle, fiction, and history. Including an interview with Cory Doctorow and how to make hydrogen airships out of condoms."
3D printing is being condemned in the media because of the potential for printing guns. Engineers at Michigan Tech believe there is far more potential for 3D printers to make our lives better rather than killing one another. To encourage thinking about constructive uses of 3D printing technology Michigan Tech Open Sustainability Technology (MOST) Lab and Type A Machines is proud to sponsor the first 3-D Printers for Peace Contest.
A fully assembled Type A Machines Series 1 3D Printer goes to first place and a MOST RepRap 3D printer kit will go to the second prize winner who create designs that enable 3D printers to encourage peace. Winning open-source designs will discourage conflict (e.g. designs for appropriate technology in the developing world to reduce scarcity or designs that improve economic development -- see examples and pictures). Designers are encouraged to consider: If Mother Theresa of Ghandi had access to 3D printing what would they print? What kind of designs could help reduce military spending and conflict while making us all safer and more secure?
Michigan Tech has already saved tens of thousands of dollars using 3D printable scientific and engineering equipment and our labs have developed 3D printable tools to test water quality, recycle waste plastic and found that 3D printing consumer goods is better for the environment than shipping conventional goods from China.

My new Guardian column, "Privacy, public health and the moral hazard of surveillance," discusses the way that the governments' reliance on social networks for intelligence purposes means that they can't intervene to help their populations get better at trading their privacy for services.
That's a crisis. If online oversharing is a public health problem, then the state's decision to harness it for its own purposes means that huge, powerful forces within government will come to depend on oversharing. It will be vital to their jobs – their pay-packets will literally depend on your inability to gauge the appropriateness of your online disclosure.
They will be on the same side as the companies that profit from oversharing, because they will, effectively, be just another firm that benefits from oversharing.
It's as though Scotland Yard decreed that obesity was critical to its ability to catch slow-moving, easily winded suspects. It's as though the NHS announced it would cope with the expense of an aging population by encouraging chain-smoking. The dangers of oversharing are hard enough to manage when it's just the private sector that benefits from them.
DeviantArt's TommyFilth modded a KitchenAid mixer and gave it a perfect Boba Fett makeover: "I asked for a Kitchenaid mixer for Christmas, I pointed my wife toward a broken one on eBay so that I could refurbish it, as I was taking it apart I got some inspiration for the paint job and this is what came out of it, still needs a phase board for speed control and two decals to be applied to the sides but I couldn't wait to share."
Here'a an excellent piece on the promise and peril of "smart cities," which could be part of a system to make cities fairer and more transparent, or could form the basis for an authoritarian lockdown. As Adam Greenfield says, "[the centralized model of the smart city is] disturbingly consonant with the exercise of authoritarianism." The author mentions Greenfield's upcoming book "The City is Here for You to Use" (a very promising-looking read) as well as Smart Cities: Big Data, Civic Hackers, and the Quest for a New Utopia, which is out in the fall.
These critics are advocating not that cities shun technology, but that they foster a more open debate about how best to adopt it—and a public airing of the questions cities need to ask. One question is how deeply cities rely on private companies to set up and maintain the systems they run on. Smart-city projects rely on sophisticated infrastructure that municipal governments aren’t capable of creating themselves, Townsend points out, arguing that the more they rely on software, the more cities are increasingly shunting important civic functions and information into private hands. In recent talks and in his upcoming book, “Smart Cities: Big Data, Civic Hackers, and the Quest for a New Utopia,” Townsend portrays companies as rushing to become the indispensable middlemen without which the city cannot function.
Cities can easily lose leverage to private companies their citizens rely on, as the persistent battles of political leaders against telecom companies over price increases show. And private-sector software can operate behind a veil: Townsend says that while cities have made lots of data freely available online, there’s less concern about opening up the proprietary tools used to analyze that data—software that might help a city official decide who is eligible for services, or which neighborhoods are crime hotspots. “It’s the algorithms in government that need to be brought out to the light of day, not the data,” he says. “What I worry about are the de facto laws that are being coded in software without public scrutiny.”
Another concern is what will be done to protect the huge amount of data cities can gather about their citizens. The wealth of video at the Boston Marathon bombings, though it came from private cameras, showed how useful surveillance footage can be—and also how pervasive. Cameras, sensors, and tracking technologies like the Mass Pike’s EZPass can reveal a great deal about your life: where you live and travel, what you buy, even what time you take a shower. Smart grid utility-metering systems, for instance, collect and transmit detailed energy consumption information, which help consumers understand and curb their energy use but can also reveal their habits. As such, they have come under fire for threatening privacy and civil liberties, and several states have adopted legislation governing what kind of data can be shared with third parties and how customers can opt out. In Massachusetts, automated license plate recognition technology used by police cruisers has raised concerns about authorities tracking the whereabouts of citizens. The American Civil Liberties Union of Massachusetts has been pushing for a License Plate Privacy Act that would limit law enforcement’s ability to retain and use the information.
No government in Canadian history has been as hostile to science as Stephen Harper's Conservatives. John Dupuis has assembled a brief, brutal chronology of the ways that the Tories have attacked Canadian science. It's no coincidence that this government is so hostile to science, seeing as how its funding and grassroots support come from the tar sands and related Big Oil interests, who want as little known as possible about the impact of their dirty industry on the planet we all share.
This is a brief chronology of the current Conservative Canadian government’s long campaign to undermine evidence-based scientific, environmental and technical decision-making. It is a government that is beholden to big business, particularly big oil, and that makes every attempt to shape public policy to that end. It is a government that fundamentally doesn’t believe in science. It is a government that is more interested in keeping its corporate masters happy than in protecting the environment.
As is occasionally my habit, I have pulled together a chronology of sorts. It is a chronology of all the various cuts, insults, muzzlings and cancellations that I’ve been able to dig up. Each of them represents a single shot in the Canadian Conservative war on science. It should be noted that not every item in this chronology, if taken in isolation, is necessarily the end of the world. It’s the accumulated evidence that is so damning.
Here's a mesmerizing gallery of "Fabrege Fractals" created by Tom Beddard, whose site also features a 2011 video of Fabrege-inspired fractal landscapes that must be seen to be believed. They're all made with Fractal Lab, a WebGL-based renderer Beddard created.
Troy Maye was wanted for a string of identity thefts, but the IRS couldn't positively identify him. But after he passed a thumb-drive of stolen data to an IRS informant, investigators were able to pull his name off the drive's metadata. They used that to find his Instagram profile, and found a food-porn photo he'd taken at the Morton's steakhouse where he'd dined with the informant. Busted.
"IRS Agent Louis Babino then headed to Google and located Maye’s Instagram page, which contained a profile photo of Maye. When shown the profile photo, the CW confirmed that Maye (seen at right) was the man with whom he dined at Morton’s."
Well, sure, Agent Babino, but how can you be really sure this was your guy?
"A further review of Maye’s Instagram page, Babino noted, revealed “a photo of a steak and macaroni and cheese meal containing the caption ‘Morton’s.’” The image--uploaded on January 7 at 11:24 PM--“appears to coincide” with the CW’s meeting at Morton’s, added Babino."
Yup, this guy food-porned his way into being arrested. The Instagram photo is reportedly being entered into evidence in the case, so one hopes the juicy steak and the creamy mac and cheese was really, really worth all the trouble Maye is now in. Once again, if you're a criminal, online narcicism is probably something you'd be best to avoid.
Remember the gigantic data-center that the NSA is building in Utah in order to (illegally) process the electronic communications of the whole world? Turns out that the state of Utah plans on taxing the titanic amounts of electricity it will consume at 6%. The NSA is pissed.
"We are quite concerned [about] this," Harvey Davis, NSA director of installations and logistics, wrote in the April 26 email, obtained through a Utah open records law request.
In a follow-up email Davis sent 31 minutes later, he explained: "The long and short of it is: Long-term stability in the utility rates was a major factor in Utah being selected as our site for our $1.5 billion construction at Camp Williams. HB325 runs counter to what we expected."
HB325, which Herbert signed into law April 1, benefits the Utah Military Installation Development Authority (MIDA). It allows the entity, which was set up to put select military properties on the public tax rolls, to collect a tax of up to 6 percent on Rocky Mountain Power electricity used by the Utah Data Center.
