EBay of course! It turns out that the Jivaro Indians in Ecuador have toned down their warlike nature for the sake of commerce, and they're cranking out tsantsa (their word for shrunken heads) by the carload. Thankfully, they make them from goat and alpaca skins now, instead of their neighbors. These specialized tribal craftsmen haven't quite mastered the delicate art of quality control, so the heads vary in quality from laughably fake to chillingly realistic. It takes some know-how to score a really good one.
There are two philosophies to shrunken head buying at eBay... If you like gambling, buy a lot of five or more at a time. The variability of the manufacturing process guarantees that each head is totally unique and has its own personality. You may have to sift through a bunch to find the one you like. You can always give away the rejects as hostess gifts at parties for the next few years. If you are a dedicated soul and desire a "de-luxe model", scour eBay until just the right head turns up. You might pay a bit more, but you'll have the perfect facial features and hair color to match your home's decor.

For those that haven't heard, LeafLabs' Maple board is an Arduino-compatible microcontroller platform based on an STM32 ARM Cortex-M3 chip. The full feature list includes -
- Microcontroller: STM32 F103RB
- Clock Speed: 72 MHz
- Operating Voltage: 3.3V
- Input Voltage (recommended): 3.0V-18V
- Digital I/O Pins: 39
- Analog Input Pins: 16
- Flash Memory: 128 KB
- SRAM: 20KB
- 64 Channel nested vector interrupt handler (including external interrupt on GPIO's)
- Integrated SPI/I2C and 7 Channels of Direct Memory Access (DMA)
- Supplies up to 800mA @ 3.3v
- Support for low power and sleep modes (<500uA)
- Dimensions: 2.05"x2.1"
I recently got my hands on one of these new boards, and although a fully-functioning version of the Maple IDE has yet to be released, I compiled available source files from the project's repository, allowing me to upload a sketch from Windows XP (via Parallels on OS X).
My example sketch uses the shiftOut function to create a sine waveform via an MCP4921 DAC chip. I also ran the same test setup on an Arduino Duemilanove (ATMega328p) and superimposed the two resulting signals for the sake of comparison -
Arduino Duemilanove (ATMega328p) in blue, LeafLabs Maple (STM32F103RB) in green
Note - differing voltage ranges due to difference in DAC VREF (5V, 3.3V)
As expected, Maple's STM32 (running @ 72MHz) updates the DAC a whole lot faster than Arduino's ATMega328p (@ 16MHz) - in fact about 9 times faster! This was a bit of a surprise to me as I'd only expected a 4.5x speed boost considering the difference in clock speeds. Definitely good news for Arduino users in need of extra clock cycles, but for most, the Duemilanove still offers big advantages - specifically:
Jim Kelly, who's doing a daily online lab journal, working his way through Make: Electronics, is now six experiments into the book. Looks like he's having a ball. He has people looking over his shoulder from all over the world, 25 registered followers, and is started to get decent numbers of comments and questions from readers. He's even decided to run a contest to give away one of the Maker's Notebooks we sent him.
BTW: One of the questions he was asked was whether he was hired by us to do this site. He was not. He's just a curious maker who thought, since he was going to be doing all of the projects in the book anyway, he might as well do them "out loud," in a weblog, so other makers learning electronics could benefit from his own process. He was kind enough to ask for our permission beforehand, which he didn't need to do, and we did sent him two Maker's Notebooks, in hopes that he'd use them to document his experiments. That's the closest thing to a shameless commercial move here. As you can imagine, we're thrilled he's doing this and think it'll be of huge benefit to current and future readers of the book.

Thanks to everyone who entered the Alex Rider Dream Gadget Contest! We had a great time checking out all of the entries with lasers, grappling hooks, and other spy-stealth goodies, all designed by Alex Rider fans ages 8-18. It was a hard decision, but the winners are in!
Grand Prize Winner:

The Listening Cup by "nic", who writes:
Many people have used cups to eavesdrop through walls and doors, but I don't think it works very well. This is the eavesdropping cup with a modern improvement: It has a built-in mic and small amplifier circuit built into the fake bottom. A small earbud speaker on the very bottom of the cup lets the user hear everything.
Project Materials:
- an opaque plastic cup
- a small circle of plastic to form the fake bottom
- circular PCB
- an amplifier IC (like the LM386)
- a small speaker, like an earbud speaker or similar (can be pretty much any size, just so long it fits in the cup!)
- a small microphone sensor
- a little trimpot to adjust volume
- a coin cell or an external (hopefully hidden) power source
Nic will receive the grand prize package which includes:
Runners Up:

Copter Cam Aerial Recon/Surveillance unit by "The Bear Builder," who writes:
This looks like a fountain pen. Inside is a disposable flying camera and transmitter based on the design of an ash tree seed pod, and vertically launched with a simple rubber band catapult up to about 200 feet up. As it slowly spirals down, it feeds a 360-degree scan of the area via wi-fi to Alex's PDA or cell phone. Software in the PDA decodes the spiral scan into a scrollable 360-degree still image in 2-D or 3-D.
Project Materials: Advanced lithium watch battery is tiny, holds a charge a long time but has high output for the short run time of the camera and transmitter. The copter part is made of molded plastic, so as not to show up on radar, and the single airfoil blade contains the transmitter wire embedded in its leading edge. The really complicated part is the software in the PDA that senses repeating bright and dark points in the spinning video feed and lines them up to progressively build a scanned image much like an early mechanical TV camera. By layering identical angles from two offset heights, you can create stereoscopic 3-D stills as well.
Inspiration for creating this gadget: We play with rubber-band-launched whirligig toys in the summer time, and it is fun in fall to watch ash and maple seeds fly down. This unit is based mostly on an ash tree seed which fits the secret fountain pen better than the fatter maple leaf pod shape. Right now university researchers are working on radio-controlled versions of this idea, called "monocopters", but my version is non-motorized, slim and small; a light-weight, one-time-use spy tool version that's very stealthy. The rubber band launcher is low-tech, efficient, common and innocuous, a good thing for spy tools.
Scenario in which you would use this gadget: Anywhere you need a quick bird's-eye view, you would shoot this silently up overhead, and grab a 360-degree scrollable aerial view, in 2-D at night, optional 3-D in daylight. Good for getting a current sense of the "Big Picture" where you don't have Google Maps, or seeing the bad guys you are chasing from a safe distance, revealing any ambush they may have planned. What's on the roof of that building? How do I get out of this maze? The copter cam can show you.
Altoids Tin Rangefinder by "electronicsguru," who writes:
This is a fully operational "time-of-flight" style laser rangefinder that fits perfectly inside of an Altoids tin. Enclosed in the tin are 4 things : #1: x7 viewfinder #2: Nd:YAG transmitting laser with appropriate circuitry #3: Receiver with appropriate circuitry and LCD screen #4: 6 VDC Li-PO battery pack To use the rangefinder, the lid is first opened. Since the viewfinder is on the same hinge, when the lid opens, it pops up as well. Then the battery pack is connected to the circuits, powering them up. Then the receiver is pulled up, then the laser it pulled up. The receiver and laser are already perfectly calibrated to align.The laser transmits continually and the receiver picks it up. The range, azimuth, and elevation is then shown on the LCD connected the receiver circuit board in whatever units Alex chooses. To stabilize the rangefinder, three stick pens with holes drilled in then 3/4 of the way up are held together with a steel pin. The writing end sticks into whatever strata Alex happens to be on, while the opposite end has adhesive dots to stick to the bottom of the tin.
Scenario in which you would use this gadget: Alex Rider is behind enemy lines in a foreign country and in a jam. There is an enemy fortification in the distance preventing him from continuing his mission and he needs to hit it with some artillery fire from support behind him. He uses the rangefinder to calculate the azimuth and elevation of the target as well as the distance away from him so the artillery will not hit him. He calls in the information to the support and they hit it dead on. Alex is victorious and can continue with his mission.
The Bear Builder and electronicsguru will each receive:
Congrats to the three winners and thanks to everybody who participated!

Noah Shactman just brought Israeli defense contractor Urban Aeronautics' AirMule VTOL UAV project to my attention. The photo released by Urban Aeronautics, shown above, purports to show the first successful hovering flight of an AirMule prototype, secured against wandering off by guy-wires. Video would've been more persuasive. The design goal of the AirMule project is to produce an unmanned vehicle that can be used to ferry supplies into, or wounder soldiers out of, a hostile, closely-packed urban combat environment.

"Phineas Gage: Neuroscience's Most Famous Patient"The railroad-construction company that employed (Gage), which had thought him a model foreman, refused to take him back. So Gage went to work at a stable in New Hampshire, drove coaches in Chile and eventually joined relatives in San Francisco, where he died in May 1860, at age 36, after a series of seizures.
In time, Gage became the most famous patient in the annals of neuroscience, because his case was the first to suggest a link between brain trauma and personality change. In his book An Odd Kind of Fame: Stories of Phineas Gage, the University of Melbourne's Malcolm Macmillan writes that two-thirds of introductory psychology textbooks mention Gage. Even today, his skull, the tamping iron and a mask of his face made while he was alive are the most sought-out items at the Warren Anatomical Museum on the Harvard Medical School campus.

Announced at this year's CES, Flir's Scout gives consumers true thermographic vision -- imaging based not on light but on heat. Flir is marketing the Scout to consumers but it's hard to see Joe Sixpack wanting to drop $3K (MSRP) on one. Which is not to say it doesn't have its obvious uses -- for instance, a hunter could use it to follow a blood trail at dusk, or a homeowner could pinpoint heat leaks.

Built around Flir's leading edge thermal night vision technology, Scout gives outdoor enthusiasts the power to see people, animals, and their surroundings clearly in total darkness, as well as through smoke, dust, and light fog. Scout uses a thermal camera to make video images from heat, not light, and displays this video on its built?in LCD eyepiece.Read more | Permalink | Comments | Read more articles in Imaging | Digg this!
In addition to providing improved visibility in almost every conceivable environmental condition, Scout enables hikers, campers, and hunters to keep track of other people in their party, find and track animals, and navigate safely and accurately even in total darkness.

Each year, John Brockman of Edge.org asks a question of a number of science, tech, and media personalities, and compiles the answers. This year's question: "How is the internet changing the way you think?" Lots of good, meaty responses that make for great reading, from interesting people whose work ideas have been blogged here on Boing Boing before: Kevin Kelly, Jaron Lanier, Linda Stone, George Dyson, Danny Hillis, Esther Dyson, Tim O'Reilly, Doug Rushkoff, Jesse Dylan, Richard Dawkins, Alan Alda, Brian Eno, and many more.
I'm far out-classed by the aforementioned thinkers. But here's a snip from my more modest contribution, "I DON'T TRUST ALGORITHM LIKE I TRUST INTUITION":
I travel regularly to places with bad connectivity. Small villages, marginalized communities, indigenous land in remote spots around the globe. Even when it costs me dearly, on a spendy satphone or in gold-plated roaming charges, my search-itch, my tweet twitch, my email toggle, those acquired instincts now persist.Read the rest.The impulse to grab my iPhone or pivot to the laptop, is now automatic when I'm in a corner my own wetware can't get me out of. The instinct to reach online is so familiar now, I can't remember the daily routine of creative churn without it. The constant connectivity I enjoy back home means never reaching a dead end. There are no unknowable answers, no stupid questions. The most intimate or not-quite-formed thought is always seconds away from acknowledgement by the great "out there."
The shared mind that is the Internet is a comfort to me. I feel it most strongly when I'm in those far-away places, tweeting about tortillas or volcanoes or voudun kings, but only because in those places, so little else is familiar. But the comfort of connectivity is an important part of my life when I'm back on more familiar ground, and take it for granted.
And here's the complete index of responses. (Image: Katinka Matson)
Almost a third of our portfolio is under attack by patent trolls. Is it possible that one third of the engineering teams in our portfolio unethically misappropriated technology from someone else and then made that the basis of their web services? No! That's not what is happening. Our companies are driven by imaginative and innovative engineering teams that are focused on creating social value by bringing innovative new services to market.It's really difficult to see how anyone can be intellectually honest with themselves and not be in favor of an independent invention defense. It's difficult to see how anyone could justify the idea that even if someone comes up with something totally independently, they can't use their own inventions.
Our companies are being attacked by companies that were not even in the same market, very often by companies they did not even know existed....
I know of no case where the engineers in one of our companies were aware of the patents that are now being used to attack them. The moral rightness of this screams at me. If, as an engineer focused on solving a problem, I happened to come up with an idea that is in some way similar to yours, then that in itself should suggest that it was obvious and not patentable. Unfortunately, that does not really help. There, the burden of proof is still on the startup and it is still smarter to settle than to burn precious capital on a defense.
If, on the other hand, the troll was required to show the startup had some prior knowledge of their technology, the burden would be shifted to the attacker, and this blatant abuse would come to a grinding halt. If you believe as I do that innovation is key to social progress, please support patent reform. It is a complicated issue, but an independent invention defense is an obvious place to start.
This is my new favorite picture of Mars.
From Phil Plait:
The eternal Martian wind blows the heavy sand into dunes, and you can see the hummocks and ripples from this across the image. The sand on Mars is from basalt, which is a darkish gray color. The red comes from much smaller dust particles which settle everywhere.This High Resolution Imaging Science Experiment site has more photos so can zoom in and look for Dejah Thoris.But what are those weird tendril thingies?
In the Martian winter, carbon dioxide freezes out of the air (and you thought it was cold where you are). In the summer, that CO2 sublimates; that is, turns directly from a solid to a gas. When that happens the sand gets disturbed, and falls down the slopes in little channels, which spreads out when it hits the bottom.

While at MIT last week, I met Jonathan Ward, who's working in the Machines That Make (MTM) group on an open source, low-cost CNC mill made from 26 parts on a ShopBot, called the MTM A-Z. You can download the necessary files (including bill of materials) to make your own! Check out the video above for an overview of the machine. The MTM group has this awesome idea of a fablab 2.0, where all of the big machines will have been made by other machines, reducing commercial overhead and increasing overall awesomeness.

I'm having trouble believing that RCA's Airnergy, a "WiFi hotspot power harvester" unveiled at CES, can actually charge its internal battery from WiFi radio signals.
From OhGizmo!:
The Airnergy has a battery inside it, so you can just carry it around and as long as you're near some WiFi, it charges itself. Unlike a solar charger, it works at night and you can keep it in your pocket. Of course, proximity to the WiFi source and the number of WiFi sources is important, but at the rate it charges, if you have a home wireless network you could probably just leave anywhere in your house overnight and it would be pretty close to full in the morning.A commenter on OhGizmo! offers the following:
Here's some math. Long story short, by my calculations, 100% efficiency and absorption at 5 feet away from a 100mW home router, (reasonable figures), it would take 34.5 years to charge that blackberry battery.(BTW, What is that dent in the gadget about? Looks like someone poked it with an awl.)It's not a Dyson Sphere, so you only get the power that hits the antenna.
Surface of a sphere = 4pir^2, r = 60" (5 feet).
Surface area of a 5' sphere = 45,216 square inches.
The device appears about 2" x 3" = 6 square inches.
The device then picks up, best case, 0.000133 of the power out from the router, which is 100mW, so.. 0.0133mW
If you leave it there for 24 hours, 0.0318 mWh are stored.
According to Will's battery, it has ~4,000 mWh capacity.
So, it would take 12,579 days, or 34.5 years, to charge your blackberry battery once, presuming 100% absorption, no losses.

BoingBoing readers who follow the work of British funnyperson Peter Serafinowicz (he of the soon-to-be-released DVD!) know the guy plays a mean Paul McCartney. Remember "I'll Kill"? Apparently, Robert Zemeckis agrees: the director cast Serafinowicz as McCartney in his 3D Disney remake of the animated Beatles classic Yellow Submarine.
John Lennon will be played by Dean Lennox Kelly (Shameless, Frequently Asked Questions About Time Travel), George Harrison by Cary Elwes (Christmas Carol, Princess Bride), and Adam Campbell (Epic Movie) is Ringo Starr. Although, as you can see from the "Peter Serafinowicz Show" clip above, Serafinowicz could have easily taken on all four roles. Physical performance of musical numbers will be mo-capped from Beatles tribute band Fab 4, but you'll be hearing the original songs recorded by the Beatles.
Serafinowicz is in Los Angeles this week, doing motion-capture for the 3D feature. This blogger spoke with him yesterday about the production. Without giving away too much of the still-under-wraps goods, I cautiously predict the project will hit vital nerd chakras for Boing Boing readers: edgy alt-comic talent, 3D animation and cool on-screen tech effects, and the cosmic Disney-Beatles vortex.
Related reports: Empire Online, Hollywood Reporter, Rolling Stone, AICN, New York Times, MTV. (Thanks, Peter Serafinowicz!)

When Amazon "sells" you a Kindle ebook, they don't really sell it to you. If you read the fine-print, you'll see that they're waving their hands furiously and declaring that you aren't "buying" the book, but rather "taking a license to a limited set of uses" for the book. Whereas a book that you buy comes with all kinds of rights, such as the right to sell or give the book away (Jeff Bezos: "[W]hen someone buys a book, they are also buying the right to resell that book, to loan it out, or to even give it away if they want. Everyone understands this.") a book that you license from Amazon comes with a very small subset of those rights, as defined by a lengthy and difficult-to-grasp "license agreement."
Despite all the fine print, most of us know that this is a scam. Declaring a sale to be a license is ridiculous on its face (imagine this: you finish a bowl of soup at the deli and when you get to the bottom of it, you find a EULA that says, "By eating this soup, you agree not to attempt to season your own soups in a similar fashion, nor to share this soup with any other person").
It's such a silly notion that even Amazon can't keep its story straight. Take this press-release in which Amazon trumpets that its "customers purchased more Kindle books than physical books." Purchased, not "licensed."
Or consider this ad (courtesy of Elix): "Kindle publications are sold by Amazon Digital Services, Inc." Again, sold, not "licensed."
(Yes, you can purchase a license. But that's not what the copy says. It doesn't say, "Amazon customers purchased limited licenses to more Kindle books...")
It's a rip-off, pure and simple. And Amazon's digital divisions won't let copyright owners get out from under it. When I tried to negotiate the distribution of the Random House Audio edition of my novel Makers through Amazon's Audible store, they refused to allow me to add legal text to the recording telling users that they could make any use of the audiobook that was permissible under copyright, negating their EULA. In other words, Amazon isn't doing this because the publishers insist on it: even when my publisher, Random House, the largest publisher in the world, told them that they didn't want the crazy EULA, Amazon insisted.
Don't get me wrong. Amazon's "hard goods" business is the best ecommerce system in the world. I did half my Christmas shopping there. I buy everything from books to box-files from them. They are customer-focused, efficient, and smart. But I won't buy any of Amazon's digital offerings until they clean up their act and deliver the same customer rights to e-goods buyers as they do to hard-goods buyers.

A thousand years ago, there wouldn't have been much jungle here, just terraced plots of maize and clear view off the mountain slopes to the valley far below. Visitors got a dizzying look at the drop from either side of a cobblestone road that lurched upward along the back of a steep ridge. At the edge of town, they'd find themselves funneled into a stairway shadowed on either side by stone walls and tall guard houses. Up the steps, a cobble-paved causeway stretched ahead, rising gradually, its edges lined with sculptures and the piked heads of conquered enemies. At the end, the chiefs' house stood on a tall stone foundation, its conical roof mirrored by the peak of the volcano in the distance.
The modern entrance to the ancient city of Guayabo is not nearly so dramatic. There's a pockmarked gravel road up a mountain, with chasms that threaten to swallow the front wheel of our boxy, little Honda. A wooden ticket booth, like a lemonade stand, marks the spot were you park the car on the roadside. Carefully maintained nature trails wind through rainforest less than a century old—this land was a dairy farm not so very long ago—and spit you out in the center of what was once a city of several thousand inhabitants.
Guayabo—pronounce it "Why-ahbo"—is one of many ancient cities in eastern and central Costa Rica that get overlooked by the general public, largely because their builders worked mostly with materials—wood, thatch, cane—that disintegrated in the tropical climate. The massive communal houses rotted away long ago. But the stone foundations, roads, tombs and aqueduct systems that remain are, in themselves, impressive enough to be named an International Historic Civil Engineering Landmark by the American Society of Civil Engineers.

I travelled to Guayabo—about two-and-a-half hours east of the Costa Rican capital of San Jose—with Michael Snarskis, Ph.D., an archaeologist who has spent his career living and working in Costa Rica.

Although Guayabo had been known (and looted) since the 1800s, true archaeology didn't begin there until the late 1960s. When Snarskis first visited the site in the 1970s, it was still mostly cow pasture. Today, though, the central part of the city has been cleared and a stretch of the main entry road painstakingly restored. At the city's heart is a piece of urban design that Snarskis said was as common to ancient Costa Rica as the grid-with-a-park-in-the-center is to small-town America.
Diorama showing what the center of Guayabo probably looked like during its heyday.
"You had the main road that led into the city and ended at the stairway of the chiefs' house, after passing through a sunken plaza. The plaza is quite a bit lower actually, because it's the pit left behind by digging earth fill for the principal mounds. The caciques, Spanish for chiefs, would all have lived in the house on the tallest mound. And the adjacent secondary mound would have been for the wives and female slaves who took care of their domestic maintenance. The Spanish, when they first arrived, actually described this same basic design and the division of residence by sex at other places in Costa Rica, though they never made it to Guayabo," Snarskis said.
Standing there today, the city seems too small to have packed in a peak population of several thousand, but, Snarskis points out, you have to remember that only 1/4 to a 1/3 of Guayabo is visible. The jungle on all sides is littered with house foundations and tombs, which have never been fully excavated. In a way, most of Guayabo is still a lost city, waiting to be discovered.
Open tomb in the jungle surrounding Guayabo. The walls, floor and lids of these tombs were made from lajas—slabs of volcanic flagstone.
This still-buried ring of stones marks the foundation of a small house. 
All the remains are stone: Either car tire-sized river cobbles hauled up from far-flung valleys or massive lajas—slabs of volcanic flagstone, some as long as a human body. Simply getting these rocks to the city is a big deal. Snarskis said the river cobbles were probably hauled up the mountain one-by-one in slings thrown over the backs of workers and slaves. The flagstones would have been even more difficult to pry out of the ground and move—remember, there weren't any pack animals around to help out.
Some of the principal mounds.
The chiefs' house. Multiple male elites would have lived here. Snarskis thinks the grassy plaza at the base of the steps may have once been a reflecting pool that's now filled with silt.
The work that went into building Guayabo isn't just impressive, it's also important, because it proves the existence of a fairly complex political system. Leaders need a sophisticated power structure backing them up to get monuments like this built. Without it, orders like, "Hey, I really think you should carry that 200-pound rock uphill for several miles," tend to get ignored. No ancient Chibchan calendars or writing systems have been preserved, but Guayabo and its sister cities weren't the work of cultural pushovers.
A carved stone, about the size of a large coffee table, found near Guayabo's center. Snarskis said that this side depicts a very stylized version of an alligator.
The other side, he said, shows a picture of an upside-down jaguar.
Nor were the Chibchan people technologically deficient—in fact, they were excellent engineers. Guayabo sits between two streams, which the ancient inhabitants tapped to bring fresh water into the city center. Aqueducts criss-cross the city, both in exposed stone-lined trenches and under the cobblestone-paved streets, carrying water to collecting pools. Some of these have been running continuously since they were built a millennium ago.
"In fact, the entire site is tilted slightly, and that's on purpose," Snarskis said. "It ensured the constant flow and circulation of water from the stream at higher elevation, through the city, and out the stream at lower elevation."
An aqueduct brings water from a nearby stream to fill this pool.
An aqueduct flows below this street, taking water from the pool in the previous shot, to another one at slightly lower elevation.
So far, Guayabo is the only ancient city in Costa Rica open to tourists. But there are others out there. At one time, they were probably connected by networks of roads. Less than 50 miles north of Guayabo, archaeologist John Hoopes, Ph.D., is currently digging at a similar city. He compares the ancient Caribbean to the ancient Mediterranean—two similarly sized seas, ringed by a host of cultures that were all individually unique, but constantly in contact, each trading ideas and incorporating foreign elements into their own, distinct style. The Maya may have been Central America's answer to the ancient Greeks, but that doesn't mean Chibchan culture wasn't also important. The more we learn about sites like Guayabo, the more we'll understand about the ancient Costa Ricans and how they contributed to the overall Caribbean cultural network.
Michael Snarskis offers guided tours of Costa Rica's National Museum, Jade Museum, Gold Museum and the ancient city of Guayabo. If you'll be visiting Costa Rica and you're interested in archaeology, you can contact him by email or by phone at 011-506-2235-8824.

Amazing Giant Squid by ~lanabosak
Nick Rodwell, the plaintiff, was accused by Garcia of "a ruthless drive to kill off their harmless and not-for-profit passion in his bid to keep exclusive control of the Tintin brand."
Britain's "fair dealing" offers less protection to fans and scholars than does the US's "fair use" (itself a complicated doctrine). Combined with a litigious copyright owner, it's a recipe for disaster when it comes to free speech, scholarship, and fan activity.
Tintin film boycott threat over row with Hergé widow's British husband (Thanks, Will!)Hundreds of Tintin fans have already backed Mr Garcia, who on Thursday called for a boycott of the film and claimed that many supporters were heeding his demand. More than 500 people have joined his page on the Facebook website which expresses "anger and disgust" over the issue. More supporters have also backed his cause on other websites.
Mr Garcia said: "We have nothing against Mr Spielberg even if there is a boycott threat against his film ... but are asking him to intervene in favour of not just me but all people who are being prevented from sharing their passion for Tintin..."
Stéphane Steeman, who ran the Hergé Friendship Club for 25 years, has just released a book in which he castigates Mr Rodwell for trying to kill off his organisation, called The Escalation.
He recounts how Mr Rodwell in his blog implies that two Belgian journalists criticised him because they could not pass on their passion for Tintin to their children as they were autistic.
Pierre Assouline, Hergé's French biographer, wrote that he "knows only too well" the "methods" of Mr Rodwell with his "victims".

I've written before about Steven Brust's delightful, epic Vlad Taltos novels, a long-running series of sword-and-sorcery novels about a wisecracking human assassin in a land where the ruling class is composed of ancient, long-lived elves from a variety of noble houses named for animals. Brust has turned out a dozen of these novels to date (plus five more books in the style of Dumas, set centuries before the Vlad books), and they are, to a one, absolutely cracking yarns, Fritz Leiberesque novels where the steel flashes, the spells swirl, death is dealt, heroism is on display, and cunning saves the day.
But Brust's novels are also, to a one more than just fantasy novels. Each one is also a meditation on power, on freedom, on fairness, on economics -- even on cooking. And Brust doesn't use the action to sugar-coat the "message" -- no, the message, such as it is, is integral to the action revealed through it, naturally and engrossingly, so that each book is an education unto itself.
Take Iorich, the latest book, published last week. Iorich has the exiled Vlad Taltos returning to the capital city -- where he is a hunted man -- to rescue a friend from prison. And while Vlad has to do plenty of fighting and sneaking and skulking to get her out, the main method he employs is to use the law. And so Brust is able to skilfully blend a remarkable treatise on politics, law, justice, due process and even military ethics into a novel in which there is enough sword and sorcery to fill a dozen Vallejo paintings.
There are 17 noble houses in Dragaera, and so far, we've had books name for the first 12. I'm hoping that that means that there's at least five more to come. I've been reading these since I was a kid, and they've been fine companions all my life.

If you are against software patents you are not an innovator. Innovators want patents, those who do not innovate and copy others do not want patentsThis was in response to Ian Clarke, a well known software developer, entrepreneur and someone who has argued strongly and articulately against software patents, pointing out in great detail, the harm they have done to the software industry. Clarke does a good job explaining his position, but Quinn doesn't bother responding to Clarke directly, but makes up strawmen. For example, Clarke points out that he's raised plenty of money from investors, despite being against software patents, and Quinn mocks the idea that any VCs would fund businesses without patents:
I would love to know who the investors are that are willing to provide funding for a software business that relies on trade secrets and copyrights. Naive investors like that would certainly be interested in companies with real protections. Simply stated, software cannot be adequately protected with copyrights, which I am sure you know or you should know. Likewise, trade secrets do not offer much, if any, protection for software. If the software is released the trade secret would be lost because anyone can get to the code.Note that Quinn is both ignorant of the factual situation (many of the top venture capitalists around are against software patents -- and Clarke lists out his investors, which include top tier VC firms) and then twists the story to something that Clarke did not say. Quinn seems to be of a belief that the only way a software company can be in business is with some sort of gov't backed monopoly to "protect" them. It has apparently not occurred to him that businesses survive not based on protections, but on selling products and services, and you can do that without protectionism. In fact, here in the US, we tend to recognize that competition is a good thing. I'm not sure why Quinn is so against it. Oh yeah, as for VCs against software patents, we've discussed quite a few.
Everyone knows that those who don't want patents just want to copy the work of others. Copyists are not innovators, they are a drag on everyone. Free riders are not innovators. I know you understand that, and suspect that is why you are leaving, having been defeated by logic and rational arguments. Sorry if I hit too close to home. Sorry also that you couldn't stand up to the debate and chose to run and make false allegations in the process. Not surprising though.Funny thing? Those are the same arguments used for ages before Quinn came along. He's copying them. According to his own logic, he's a drag on the system. Also, he went to law school at some point, and was given a bunch of information that he has copied into his brain. Free rider!
Innovators by definition create things that are innovative, which means they are new, non-obvious and otherwise unique. Those who engage in endeavors that are unique do not begrudge others from obtaining protections themselves, because if what they are doing is really unique there is no skin off their nose for others to obtain protections. An innovator who concerns themselves with what others are doing and demands they stop obtaining patents are really only logically saying one thing. You shouldn't get a patent and patents shouldn't be issued because I want to copy you and I don't want you to be able to prevent me from doing that.This statement has so little connection to actual innovation (especially as done in the tech world) that it's difficult to think what Quinn is possibly referring to. As anyone who has been near real innovation knows, actual innovation isn't created in a vacuum. It involves building on the ideas of others and doing more with it -- the proverbial standing on the shoulders of giants. But, in Quinn's mind, apparently, standing on the backs of giants is free riding. He goes on in that same comment to accuse Ian of lying in claiming he has raised $15 million from some of the top VCs in the world. This is stunning. Ian is not lying. The facts are not hard to find. Ian is well-known and well-respected, as are many of his investors. Quinn did, of course, try to leave himself an "out" by saying that if Ian is not lying, then his investors are "the most naive investors in the world," yet fails to note that they are actually some of the most well respected and successful VCs in the world. But, apparently that's meaningless to Quinn.

Stop-and-search powers ruled illegal by European court (Thanks, Mike!)Section 44 of the Terrorism Act 2000 allows the home secretary to authorise police to make random searches in certain circumstances.
But the European Court of Human Rights said the protesters' rights under Article 8 of the European Convention on Human Rights had been violated.
The court said the stop and search powers were "not sufficiently circumscribed" and there were not "adequate legal safeguards against abuse".

Bruce Sterling: State of the World 2010
*Okay, you've treated your future as an "unpredictable lurching thing..." and now you're all morose about that... You and your generation CREATED that situation! Ever heard of "disruptive innovation," "disintermediation," "offshoring," "small pieces loosely joined," "de-monetization," "plug and play," "the network as a platform"? Of course you've heard of all that crap, because you've been tub-thumping it your entire adult life, but what the hell did you think that was all about? Did you think you were gonna bend every effort to virtualize reality, and then get a gold railway-retirement watch and a safe place to park the cradle? Guys with stacks of gold bars and working oil wells don't have any stability now! Much less guys like you, who move their fingers up and down on keyboards for a living.*You want some security? Demand government housing subsidies and a guaranteed minimum income! They bailed out every broke mogul on the planet, they might as well bail out the civil population...
*"A coherent picture of where your future is heading." Okay, fine. Let's imagine you're three years old again. You want to give your Dad, back in 1974, a coherent picture of what 2010 looks like. You know, something very actionable, lucid and practical, where he can just slap the cash on the counter and everything works out great for the family. Okay: given what you know now about the present, tell me what you oughta tell him about 2010, back in 1974. Use words of one syllable, so he doesn't have a stroke.

The MAKE Controller Kit v2.0 is an open source hardware platform for projects requiring high performance control and feedback, connectivity, and ease of use. It can be programmed and run autonomously, or it can be used as a peripheral for desktop applications. If you make a project based on the MAKE Controller, be sure to add it to the MAKE Flickr pool, or a link in the comments. I would really like to see some of the projects that use the full power of this kit. Thanks!

The project consists of a shield you can add to an Arduino equipped with another Altmega 168/328 chip and a whole 'nother set of digital and analog I/O pins.
Instructable user johndavid400 explains:
The shield design can use the base Arduino's power supply or it can supply power to the base Arduino via it's onboard power-terminals and 5v regulator. You can select which power mode you want to use via the on-board jumper selectors.
Using I2C, you can connect 1 Arduino (master) to a host of slave Arduino's through Analog ports 4 and 5.
Also, you can add the security of having a completely separate CPU to your project that is unaffected by any code running on the base Arduino. I use this shield as a failsafe on my R/C lawnmower. The base processor uses the 2 external interrupts to sample and decode 2 servo signals from an R/C transmitter/receiver, while a 3rd servo signal is sent to the Core2duino that controls a relay for the motor-controller power supply. This way, even if there is a problem with the main code and it stops responding, the Core2duino will still be able to carry out it's main function unaffected (which is to kill the power to the bot if anything unusual happens).

Protecting "Cloud" Secrets with Grendel (Thanks, Marc!)
Of course, data on web sites is usually shared with at least some other people in some way. Sometimes a user might want to share their information with the web site support staff, so the staff can help solve a problem or fix a bug. Or, the user might want to share their sensitive data with selected other users on the site, such as coworkers or family members. Grendel allows this, letting you encrypt data with multiple keys so that more than one user's password can gain access.It's very easy to screw up when building a cryptography system -- check out Nate Lawson's excellent Google Tech Talk on common crypto flaws, or Matasano's Socratic dialog on similar topics, for a map of the pitfalls available to you, and us. We've been fortunate at Wesabe to have a number of people who think very carefully about security, and they've put a lot of effort into designing and building Grendel. That said, we have two goals in open sourcing Grendel: first, to make a tool available to others that could help make "cloud" applications in general much safer for everyone, and second, to open up what we've built so others can review and help us improve it. We would love comments on any aspect of Grendel, security or otherwise.

Cory Doctorow: Close Enough for Rock 'n' RollIn other words, rock 'n' roll is cheap, experimental and fluid, and devotes most of its energy into the production of music. Orchestral music is expensive, formal and majestic, but tithes a large portion of its effort to coordination and overheads and maintenance.
If the Internet has a motif, it is rock 'n' roll's Protestant Reformation thrashing against the orchestral One Church. Rock 'n' roll gets lots of wee kirks built in every hill and dale in which parishioners can find religion in their own ways; choral music erects majestic cathedrals that humble and amaze, but take three generations of laborers to build.
The interesting bit isn't what it costs to replicate some big, pre-Internet business or project.

Boing Boing reader John says,
The folks at the Web 2.0 Suicide Machine are looking for feedback on how to respond to a recent cease & desist letter. While they reside in the Netherlands, and cease & desist letters are not equivalent to litigation and in fact do not always have a legal leg to stand on, it still seems important to consider the implications. This comes after suicidemachine.org's IP was blocked by Facebook. Similar service/software art Seppukoo, who were similarly issued a cease & desist and have issued this response.
From the nettime announcement by Florian Cramer:
"On behalf of Facebook, the law firm Perkins Coie has sent a Cease and Desist letter to Mike van Gaasbeek from WORM , the Rotterdam-based experimental arts center of which MODDR_labs , creators of the Web 2.0 Suicide Machine , are a part of.BB reader John asks, "Can either of these services be subjected to the contracts that bind users and developers who use the Connect API from scraping data?"Suggestions for competent legal defendants for WORM/MODDR would be welcome. As a non-profit organization with roots in improvised and electronic music and avant-garde filmmaking, WORM encounters this situation for the first time. (Other media arts institutions wouldn't have legal defense strategies ready in their desk drawers either.)"

This is really interesting, a new site coming in 2010 that helps folks collect data... For the web geeks, perhaps it's like a NING or Mechanical Turk for science?...
iDoScience.org is a revolutionary new Web technology that allows citizen scientists, teachers, and students of all ages to collaborate with professional scientists on science projects of all kinds. Now people can create their own research projects and share data all over the world. Through one interface. In real time. For the benefit of all. iDoScience.org is a multipurpose forum and database granting instant access to a whole community of people who want to get their hands on science, to participate in research or to exchange scientific insights, share discoveries, and invent new and exciting ways to solve the world's problems.Galaxy Zoo has worked out pretty well, perhaps this will encourage thousands of other projects like it. The decade of science could really have some great examples of regular folks contributing to large discoveries, a mix between SETI-type projects and perhaps more specific problems being "crowd-sourced" as they say..
