MBCook recommends Kacie Kinzer's tweenbots page, which documents some of her experiments with small, anthropomorphized robots that need help. Kinzer is writing a thesis (at the Center for the Recently Possible) centered around investigating whether people in New York City will help a cute little robot to get where it's going. "Tweenbots are human-dependent robots that navigate the city with the help of pedestrians they encounter. Rolling at a constant speed, in a straight line, Tweenbots have a destination displayed on a flag, and rely on people they meet to read this flag and to aim them in the right direction to reach their goal."

wizzor writes in with a follow-up on the Finnish municipal election in which 2% of the votes were lost by a defective e-voting system, and which the Helsinki Administrative Court had found acceptable. Now the Supreme Administrative Court of Finland has rejected the election results (original in Finnish; bad Google translation here) and ordered the election to be re-run. The submitter adds, "Apparently 98% of the votes isn't enough to determine how the remaining 2% voted, after all."

GAMA-GO's Greg Long snapped this photo of a flyer for a dog walking service in San Francisco. I agree that the artwork is rather odd. Click the image for the full flyer.

Apparently an increasing number of young people enjoy "smoking" crushed Smarties candy. They inhale the candy dust into the mouth and then exhale, producing what looks like thick smoke. (Above is just one of many video demos on YouTube.) Guess what? It's generally a bad idea. From WCBS:

Mark Shikowitz, a Long Island ear nose and throat specialist, treated a 9-year-old who had pieces of candy lodged in his nose.

"He told his parents that he felt his nose was burning," Dr. Shikowitz said.

The candy eventually dissolved, but Shikowitz said kids could also accidentally inhale the fine powder down the wrong pipe.

"That irritation can cause you to cough, can cause you to laryngospasm, which is your voice box spasming and closing," Shikowitz said.

If the sugar sits in the lungs or in the nasal cavity for a prolonged period of time it could cause an infection.

"Any time you have a substance such as sugar in these areas, which are moist, it creates a terrific growth medium for bacteria," Shikowitz said.

In this intermediate soft circuit tutorial, I show you how to make a light-up patch that can be used on your backpack for fun and bike safety. If you missed my LilyPad Arduino 101, you may want to watch that first. The theme of this year's Maker Faire is "Re-Make America" so I thought I'd add some red, white, and blue LEDs to my messenger bag. I added them to a removable patch (from the fatlab, an artist collective I'm part of) so I can easily remove it at the airport, in the rain, etc. I used a rechargeable lithium polymer batter to power the whole thing because it's flatter, lasts longer, and can be recharged instead of thrown away. I also made an Instructable where you can find links to all the supplies I used. You can download the source code and schematic for this project to get started on your own!

An anonymous reader alerts us that an outfit called Magpie is paying Twitter users to tout advertisers' products. Marshall Kirkpatrick of ReadWriteWeb has identified a number of household-name companies — among them Apple, Skype, Kodak, Cisco, Adobe, Roxio, PC Tools, and Box.net — whose products are hyped by identically worded, paid Magpie tweets. But comments to Kirkpatrick's post, including one from a Box.net spokesman, make it sound likely that these shills were paid for not by the companies themselves, but by affiliate marketers. That may not matter. In the same way that Belkin recently got burned paying consumers to write complimentary online reviews about the company's products, the makers of products and services touted through Magpie may find themselves tainted in the backlash from this new form of astroturfing. Kirkpatrick concludes his post: "So there's the Twitter-sphere for you! Bring on 'real time search,' bring on a globally connected community, bring on vapid, vile, stupid shilling. It all seems pretty sad to me."

Last week I wrote a piece that was only superficially about the finale of Battlestar Galactica, it was also about Twitter -- as almost everything seems to be these days.

There's been an interesting discussion that started on Twitter but developed in FriendFeed, about historic parallels, wondering if Netscape was to Microsoft as Twitter will be to Google.

I reserved judgement on BSG, I think I have to watch the whole series again to figure out what it was about. There's some stuff I don't understand, for example, at the beginning they make it plain that humans created the Cylons, in relatively recent history, but as the series progresses they go back further in time, and it seems there were Cylons long before humans had the technology to invent them? Weird. But I'm sure there's an explanation. Maybe you can offer a clue in a comment?

Anyway, I'm halfway through the first part of the opening miniseries, and as the bombs were going off, as Caprica is being destroyed, Balthar says: "There must be some way out of here."

Holy Hannah!

I stifled a shriek when I heard this (it would be unbecoming for a person of my stature and girth to shriek). What craftwork. Even if they went back and watched it and decided to make Watchtower the theme song, or if they planned the last episodes as they were writing the very first one -- it's amazing continuity and attention to detail. Now I really want to watch the whole series again..

Anyhow, I'm totally loving the 40-twits project. I'm looking for two or three other prolific Twitter linkers who cover tech and politics to join our little club of curators. Be sure to say what your Twitter account is. I have lots of ideas for continuing the development. It feels like a project with legs.

Photo from Third World Tech

Third World Tech is a neat site with loads of technologies that are used and created in the developing world.

One feature on their site is this great idea of making bamboo bikes. The bicycle is such an incredibly important tool for people living on very little in low tech countries. Unfortunately, steel and aluminum bikes have to come from someplace else. By using bamboo for parts of the frame, local people can grow their own bikes.

Despite the critical need for bicycle transportation in Africa, there are no bike-building businesses. All bicycles are instead imported, and these relatively few imported bicycles are designed for well-paved roads, inappropriate for rural transportation in these regions. The Bamboo Bike Project is filling that gap. Who would've thought, a bicycle made mostly out of bamboo?! But this plant's stalk is surprisingly very strong and shock-absorbent. Bicycles built with bamboo frames will allow Africans to use only a few pieces of imported parts, building the rest out of local and native bamboo.

Here is a pointer to more info on the Bamboo Bike project, and a pdf about the idea.

Death Metal writes with this excerpt from a story about COBOL's influence as it approaches 50 years in existence: "According to David Stephenson, the UK manager for the software provider Micro Focus, 'some 70% to 80% of UK plc business transactions are still based on COBOL.' ... Mike Gilpin, from the market research company Forrester, says that the company's most recent related survey found that 32% of enterprises say they still use COBOL for development or maintenance. ... A lot of this maintenance and development takes place on IBM products. The company's software group director of product delivery and strategy, Charles Chu, says that he doesn't think 'legacy' is pejorative. 'Business constantly evolves,' he adds, 'but there are 250bn lines of COBOL code working well worldwide. Why would companies replace systems that are working well?'"

AndreV writes "We've entered into an extraterrestrial quid pro quo with our Northern neighbors: After celebrating 25 years of the Canadarm's first venture into space, NASA has reached out (so to speak) to the Canadian Space Agency and begun research and development on a new generation of robotic arms, which would ultimately be used for the US agency's Orion Crew Exploration Vehicle that will provide transportation for Moon missions and jaunts to the international space station. In exchange, Canada will trade the robotic-limb technology's use on Orion and other future US-manned spacecraft for flight time for Canadian astronauts. And seeing solid results shouldn't be far off — the engineering company designing the bionic branch, responsible for the previous Canadarms, has already begun investigating the effects of zero gravity on their components. (Another forward-looking project being bartered for astronaut time is a rover for the Moon and Mars.) Fair trade?"

Over on Boing Boing Gadgets, our Lisa's written a fabulous tutorial on building your own dogshit composter -- something that'll bring up the Easter daisies a treat.

This is Ruby's butt, a great source for fresh, fertile minpin poop. She eats pretty healthy food--broccoli, carrots, lean ground turkey, some California Naturals kibble, so I'm assuming her poop's made up of a lot of the same stuff too.

My friend Christian, who famously composts his own (bigger) dogs' poop, clued me into the importance of red wiggler worms, so I decided to go to nearby Buena Vista Park to dig for some. People use them to compost human waste, too. If you're not into digging for worms, hardware stores sell things like septic starter or commercial fertilizer that can also do the trick.

An anonymous reader writes "Tuesday saw elections for school boards and city officials throughout Kansas. In Saline, ES&S voting machines in several locations were 'mis-calibrated,' and when the voter touched next to one candidate's name, the 'x' appeared next to another one. One person I talked to said he tried to vote three times before going to the 80-something-year-old election worker, who told him 'It was doing that earlier, but I thought I fixed it.' From the story in today's Salina Journal: 'The iVotronic machines used in Saline County are sold by Elections Systems and Software. In October, the Brennan Center for Justice at New York University School of Law notified 16 secretaries of state, including Kansas Secretary of State Ron Thornburgh, that the machines are known to record votes to the wrong candidate.' The county does calibrate the machines the day before each election, but, '... in conversations with ES&S on Thursday, [the county clerk] was told that the calibration might change during the day. "What they've seen is calibration drift on a unit," Merriman said. "They're fine in the morning, but by afternoon they're starting to lose their calibration."' There was also coverage of the problems when they occurred two days ago."

Anyone seen driving while distracted - eating at the wheel, playing with the radio or applying make-up for instance - is filmed by the cameras.

Later, a letter is sent to the owner of the car, in many cases along with a fine.

Anyone caught using their mobile will be asked to pay £60 and have three points added to their licence. Fines could also be handed out to anyone who is thought to be driving without due care and attention, or similar offences.

Pamela Samuelson, one of America's leading copyright scholars, has published a working paper arguing that the DoJ's and RIAA's theory for calculating damages in downloader lawsuits is flawed:

A working paper coauthored by noted copyright law scholar Prof. Pamela Samuelson of the University of California Law School discusses, in depth, various issues regarding statutory damages under the Copyright Act.

Among other things, the paper concludes that the State Farm/Gore due process test is applicable to statutory damage awards under the Copyright Act, a position which is consistent with the position taken in the amicus curiae brief filed by the Free Software Foundation in SONY BMG Music Entertainment v. Tenenbaum, and inconsistent with the positions taken by the Department of Justice in Tenenbaum and in SONY BMG Music Entertainment v. Cloud

Working paper by Prof. Samuelson on Copyright Act statutory damages argues Gore due process test applicable to statutory damages (via /.)

An anonymous reader writes "It's been a long-talked-about but never fully realized aim of developers, publishers and format holders to create a game that runs on multiple platforms, but connects and exchanges assets between them — e.g. you play a game as an FPS on a console/PC but control it as an RTS on mobile devices. Now, Rockstar Games seems to have cracked it, on a small scale, with news that a new Flash game will allow PC gamers to generate in-game cash — true to form for GTA-creator Rockstar, it's through 'money laundering' — that is then transferred to its new Nintendo DS title, Chinatown Wars. GameSpy's online technology seems to be responsible for this latest gimmick, but most interesting is the idea that this could allow an interface between platforms like the iPhone and consoles as well. How long until an indie developer creates an MMO that has different interfaces for PC and mobile?"

Among the interesting effects he discusses in this interview for O'Reilly Radar is that users of their product, Whrrl, have talked about changing their lives to make more interesting stories. Holden also talks about some of the work he did at Amazon, privacy issues that arise when social networking starts to become ubiquitous, and why he thinks the Apple App Store review system is seriously broken. 'One of the things that happens with an iPhone is when you uninstall an app, it asks you to rate it. And it defaults to one-star. ... The problem is ... there's no kind of qualification. Anybody just downloads it and checks it out or doesn't check it out, right? And I think a number of people run it and they see that you have to sign in and they just delete it.

A bunch of folks have been asking for video from my keynote talk at the excellent Mesh Conference, and here it is (and if you really want to download it, there's an iTunes link as well). It's also embedded below if you click through. The whole thing is an hour, but split into four separate videos. The first two are my presentation and the second two are the Q&A that followed:





It was, as always, lots of fun to do. Also, I met tons of great, wonderful, interesting and fascinating people at the event. Interacting with people is always the best part of these things. Thanks to everyone who came out -- and a special thanks to the Mesh Crew: Mathew, Rob, Michael, Stuart and Mark who have created something really special with the Mesh event and who are each amazing individuals as well.

Also, since people were quizzing me about it later: I actually do "memorize" the presentations and what's coming next. I don't see what the next slide is before I bring it up and no (as two separate people asked me...) I did not have a little device in my ear telling me what was coming next....

Justin McKeating asks: “Now, I’ve never had any medical training so can someone more knowledgeable please tell me what the above procedure is called and what it’s used for in a medical capacity?” (via, Why That's Delightful!)

There is a growing number of scholars questioning how to align the First Amendment's rule that "Congress shall make no law... abridging the freedom of speech...." with intellectual property law that often does, in fact, abridge freedoms of speech. I'm in the middle of reading an entire book on the subject -- which I'll be reviewing here shortly. And, just recently, we saw a court (for the first time) note that parts of copyright law were unconstitutional due to the First Amendment. Law professor Peter Friedman points us to the latest of many recent treatises on the subject, by Christina Bohannan, entitled Copyright Harm and the First Amendment, which questions why copyright law does not require any showing of "harm" to get around the First Amendment issue.

Other laws -- such as defamation -- require that in order to adbridge the freedom of speech, harm needs to be shown. And that seems like a reasonable condition. Bohanan agrees and suggests, not just that copyright law should be changed to include a burden on those declaring infringement to show that actual harm has been done, but that the First Amendment requires this. In fact, she finds it troubling that rather than putting the burden on the accuser to show harm, it's often flipped around, and the burden is placed on the defendant to prove a lack of harm -- which creates the chilling effects so many people warn about. It is these "chilling effects" that seem to go entirely against the First Amendment.

This article argues that copyright law, at least as it is applied in many cases, is unconstitutional. When there is no harm to the copyright holder's incentives, copyright law burdens speech without serving any countervailing governmental interest. Thus, the First Amendment requires proof of harm in copyright infringement cases. Consistent with the government interest in encouraging innovation, the harm requirement would allow a finding of infringement only where the copyright holder can show that the defendant's use is likely to cause real harm to the copyright holder's incentives to create or distribute copyrighted works. As such, the harm requirement would allow restrictions on speech only when necessary to keep the "engine of free expression" running. Although the harm requirement is no panacea for all speech issues in copyright law, it would help courts to identify and eliminate cases involving false conflicts between the First Amendment and copyright -- that is, cases in which there is arguably a speech interest in allowing the defendant's use and no speech interest in prohibiting it.

It's definitely a worthwhile read. Combined with some other recent scholarship, it seems likely that these issues are likely to get tested in court in the relatively near future. It would be great to see the courts recognize that copyright law has expanded so far as to violate the First Amendment in more and more situations.

An anonymous reader writes "Keir Thomas has responded to the recent raft of news stories pointing out that Linux's share of the netbook market isn't as rosy as it used to be. Thomas thinks the problem boils down to a combination of unfamiliar software and unfamiliar hardware, which can 'push users over the edge.' This accounts for the allegedly high return rates of Linux netbooks. In contrast, although far from superior, Windows provides a more familiar environment, making the hardware issues (irritatingly small keyboard, screen etc.) seem less insurmountable; users are less likely to walk away. 'Once again Microsoft's monopoly means Windows is swallowing up another market.'"

Mexican drug-related violence has been in the news a lot in the last month, so perhaps it's no surprise that USA Today is running a big article about how Mexican gangs and drug cartels use YouTube to communicate and spread messages of intimidation. Of course, two years ago, a bunch of similar stories made the news. The good news, though, is that rather than freaking out about it and demanding YouTube remove the videos, both Mexican and American officials are monitoring the videos to try to pick up clues to gang activities.
