Fixers' Collective: people learning to make broken stuff work again

Posted: 22 Mar 2011 12:44 AM PDT


Here's an inspiring story about the Fixers' Collective in Brooklyn, a co-op that holds free open surgeries where people can bring their broken stuff for repair. The Fixers make no guarantees (they learned to fix stuff by taking it apart and trying to get it back together again), but they also don't charge anything; what's more, they'll teach you what they know so you can fix your stuff yourself.
"It makes people feel proud of themselves - a little less helpless," Ms. Pittman says. "Everything breaks. Everything. These days, and especially with all this electronic equipment, we have no clue - no idea at all - how to fix stuff. We are pretty much at the mercy of our computers, our cellphones. The Fixers' Collective helped us become a little more self-sufficient. It is an attitude as much as anything."

Pittman draws a direct line from the financial crash of 2008 - "which made a lot of people, and certainly us, less inclined to trust the experts" - to the creation of the collective. But it is also true, as Pittman hints, that many Americans worry that they have become more reliant on their belongings and more disconnected about how they work.

Scholars to stop pretending they don't use Wikipedia; will work out best practices instead

Posted: 21 Mar 2011 11:49 PM PDT

Some students and profs London's Imperial College have decided to stop using scary anaecdotes to frighten students away from Wikipedia; instead, the scholars will acknowledge that kids use Wikipedia, that there's lots of good there, and will work out evidence-based best practices for learning with Wikipedia.
"Students know there is an inherent unreliablity, as it's open edited. We're not trying to hide that.

"But it's a place where you can orientate yourself when you start a topic.

"The quality has improved and the readability is often second to none," he says.

But Mr Patel says there is a real gap in knowledge about how this free resource is being used.

Rather than swapping anecdotes about the use of Wikipedia, he says his group wants to move to a more evidence-based discussion about the place of Wikipedia in universities.

It's that eggs-boiled-in-urine time of year!

Posted: 21 Mar 2011 05:15 PM PDT

Translation from China Daily article courtesy Google Translate:
China-urine-eggs.jpgIn Dongyang, has already formed such an old custom: the street vendors who sell eggs boy or lad boiled eggs to their own people, would mention a plastic bucket to a school boy to collect the urine.

Students long ago got used to this, one to three grade boys to urinate, they will align the plastic bucket outside the classroom. School teachers, but also acquiesced in such conduct, they will always remind the children during illness in the cold to the plastic bucket can not pee. The children all came to listen.

People who are not familiar with the situation should surprise: the boy with the boy in urine egg is boiled eggs, eggs in the spring of stalls selling all over the boy Dongyang streets. The boy a fifty-one eggs more expensive than ordinary eggs, can always sell out of stock.

Google's cute Street View cars were caught snorking private data from WiFi hotspots as they putt-putted their way through France. Now they must pay a US$142,000 fine. Sergei et Larry, vous mauvais garçons!

For example, at 12:45 p.m. on June 2, 2008, at an address in Marseille, France, precisely located by its GPS coordinates, Google recorded the username and password of someone logging into a pornographic website. On March 26, 2009, at 3:03 p.m., Google recorded the username and password of someone logging into a site used to arrange sexual encounters with strangers, along with the person's location along a sparsely populated rural road north of the town of Carcasonne, France.

Other examples cited included details of a patient's care from a medical information system, and an exchange of e-mail messages between two people apparently organizing an adulterous affair.

My essential Mac research applications

Posted: 21 Mar 2011 04:35 PM PDT

A few weeks ago Mark Frauenfelder posted a list of essential mac applications. He had a bunch of great suggestions that reflected his graphics and writing needs. As a long-time Mac consultant and a grad student, I thought a similar listed aimed at the research community might be a good idea. The following applications are the go-tos for my research and content creation needs -- I hope you find them useful. My apologies to Linux and Windows users -- many of these don't exist for other platforms. I'm hoping that you can suggest alternatives and software that I've missed in the comments.

papers.jpg 1. Papers ($79, $49 student price, OS X). If you use journal articles in your research, you need this software. Think of it as iTunes for academic documents. It does several things for you. It organizes groups of documents, keeps a bibliographic database linked to the documents, lets you search for current articles by journal, author, or any other criteria you can think of, both in your document collection and online. And yes, it will import and export to your EndNote [bibliography management software] database. It also supports "cite anywhere" technology that lets you search for and insert styles citation in any program that supports text input. They have a 30 day trial period, so you can download and try before you buy.

pdfpen.jpg 2. PDFPen ($60, OS X). Of course having PDFs from a journal is great, but what if you need to hilite something, join together two PDF documents, or pull text out of a scanned PDF? That's where PDFPen comes in. It is similar to the free, open-source skim, but I prefer the interface. If you're working with PDFs, either of these is preferable to Acrobat. The free trial works with all features, but includes a watermark on PDFs.

PDFKey.jpg 3. PDFKey Pro ($25, OS X, Windows). Unfortunately some PDFs that you run into are locked, meaning you can't mark them up as you would a printed copy. You can print a copy and then re-scan, or you can spring for PDFKey Pro and unlock the PDF, allowing you to mark up articles as needed. Free demo available for download and evaluation.


calibre.jpg 4. Calibre (Free, OS X, Linux, Windows). When Amazon deleted copies of books people bought for their Kindle, I decided that ebooks just weren't worth the bother. That's changed recently. First I found out that Amazon has released software readers
, so you're not tied to their hardware. Then I found out that there were alternate open source ebook readers like Calibre available, which include plug-ins that let them import ebooks in formats such as Amazon's. There is also software that will let you take control of your ebook collection. Now I can use ebooks without worrying about a company pulling the plug on the content I've paid for.


graphicconverter.jpg 5. Graphic Converter ($40, OS X). This is software that's been around on the mac from back in the 90s, and it's still being maintained and updated. In terms of fuction it's similar to Photoshop, and allows you to do pretty much any kind of image manipulation you want. The big advantage for academics (aside from the price) is that it reads around 200 different graphic formats, and outputs around 80. If you've got a file that you can't open, this should solve the problem. Free download with unlimited evaluation time (shareware).


audacity.jpg 6. Audacity (Free, OS X, Linux, Windows). What Graphic Converter is for images, Audacity is for sound files. An open source sound editor that lets you record and modify sound files in non-proprietary formats such as Ogg Vorbis, MP3, WAV or AIFF and even raw. It has a generous set of features, including frequency analysis tools of interest to biologists and linguists.


eazydraw.jpg 7. EazyDraw ($95, OS X). Way back when the Mac was new, Apple included a program called MacDraw that let you put together vector graphics. This made creation of flow charts and technical diagrams a snap. These tools eventually made their way into word processors such as Word and Pages, but they never really felt right to me. EazyDraw is the closest I've found to getting back a copy of MacDraw, though the price is a bit steep. They offer an evaluation download that limits you to creation of 20 objects, and also offer a 9 month license for $20.


livecode.jpg 8. LiveCode ($99 and up, OS X, Linux, Windows). Back in the day Apple also introduced a software development kit called HyperCard. Unfortunately at the time John Sculley was in charge, and couldn't figure out how letting end users write their own applications could be a money-maker. So HyperCard died, but was followed by a series of programs that allowed users with little coding experience to create custom software. LiveCode is a descendant of the original HyperCard, and can even import HyperCard software. It is also cross-platform. Write once and compile for your platform of choice -- OS X, Linux, Windows, iOS, android, or your browser. The programming language is simple to learn, object oriented, and very flexible. There are also a large collection of code libraries that allow you to add in specific functionality such as SQL or PDF support. If you need custom software and don't have a programmer, this is a solution. Free 30 day evaluation, education packages and pricing available.

You may have noticed that I left EndNote off the list. This wasn't an oversight. While it remains a popular bibliographic engine and does a good job of integrating with Word, the lack of real integration into other word processors is a big negative. In addition I'm tired of buying a new version when Apple releases a new OS or Microsoft releases a new version of Office. The new "cite anywhere" technology built into Papers means I can free myself from continued reliance on EndNote, and I'm happy to leave it and $100 upgrades behind.



Japan: Boing Boing Live video discussion with Matt Alt in Tokyo, 7pm ET/4pm PT/8am Japan time

At 7pm ET/4pm PT/8am Japan time today (that's at the top of the coming hour), BoingBoing's tech guru Dean Putney and I will log into a live video discussion with Tokyo-based author and translator Matt Alt (Twitter: @matt_ALT) in Japan.

[ Video link for Boing Boing Live ]

We'll be talking with Matt about the March 11 earthquake, tsunami, and ongoing nuclear crisis in Japan--and more specifically, how things are going for folks in Tokyo, what perceptions of foreign media coverage are like, and how rescue and recovery efforts are going.

This won't just be a conversation we have with each other. We're doing this through Livestream, a system that allows people watching the video to comment along in a chat room, and on Twitter. Dean will be serving as our live, on-air proudcer, taking questions from those feeds and forwarding them on to us. If there's something you've been dying to know, this will be a good way to get it on our radar.

If you want to join the conversation, just click on our Livestream page. Again, we'll start talking at 7:00pm Eastern/ 4:00pm Pacific/8am Tuesday in Japan. And, if you can't make it in time for the live chat, we'll post the full video here later.

The Integratron is in Landers, CA, near Palm Springs. From The Integratron's website:

The Integratron is the creation of George Van Tassel, and is based on the design of Moses' Tabernacle, the writings of Nikola Tesla and telepathic directions from extraterrestrials. This one-of-a-kind building is a 38-foot high, 55-foot diameter, non-metallic structure originally designed by Van Tassel as a rejuvenation and time machine. Today, it is the only all-wood, acoustically perfect sound chamber in the U.S.

Brittany Norwood, 28, is said to have then attempted to conceal the killing by tying herself up, self-inflicting wounds, and blaming the attack on two masked men.

Will the Harper government receive a #MEGAFACEPALM for C-393?

Posted: 21 Mar 2011 02:49 PM PDT

A few weeks ago, I was lecturing during a global issues course (ASIC200), when it became immediately clear that on some occasions, a solitary single facepalm is simply not enough. In fact, there seemed to be many things and events in this world that would merit many many simultaneous facepalms, or as we've been calling it in class, a MEGAFACEPALM! Anyway, when I looked it up on the internet, there didn't seem to be any pictures of large groups of people doing the facepalm, and so I thought, why not make our own? And so after a few clicks on my camera, and a handy "Make your own motivational poster" website, here is how it turned out: megafacepalm.jpg Of course, then the big question was for what occasion should we bestow this honour - this first unaltered photographic MEGAFACEPALM image? Well, I had a chat with the class the other day, and it seemed that the issue of Bill C-393 seemed like a worthy cause.

Therefore: I would like to declare that this MEGAFACEPALM will be awarded to the Harper government should:

1. Their members of Senate kill Bill C-393 by voting not to pass it.

and/or

2. They indirectly kill the Bill C-393 by "ignoring" the Bill: especially if it has anything to do with some false nonsense about election calls. Yes, we know that maybe there will be an election call, but that is neither here nor there.

So, Prime Minister Harper: the outcome is in your hands...

p.s - I realize that technically, we shouldn't call it a MEGAFACEPALM, since the name would infer the presence of a million (=mega) people doing it - but oh well, I figured this was a still good start. Besides, you can also consider this a challenge for others to create even bigger MEGAFACEPALM pictures.

Amateur radio sleuths intercept US psyops messages to Libya (audio)

Posted: 21 Mar 2011 02:22 PM PDT

"If you attempt to leave port, you will be attacked and destroyed immediately." This was the message broadcast by a secret U.S. military propaganda plane in the skies around Libya on Saturday night, just as air strikes commenced.

The "Commando Solo" aircraft told Libyan ships to remain in port, or risk NATO retaliation—and a Dutch radio geek monitoring the airwaves for information about "Operation Odyssey Dawn" heard the transmission and tweeted it.

This from Wired Danger Room's Noah Shachtman, who reports:

On Sunday alone, "Huub" has identified the tail numbers, call signs, and movements of dozens of NATO aircraft: Italian fighter jets, American tankers, British aerial spies, U.S. bombers, and the Commando Solo psyops plane.

Killing Bill C-393 equals killing period. A visual aid for Canadian politicians.

Posted: 21 Mar 2011 08:04 AM PDT

donotkillbillc393.jpg For the interest of discussion, I've made the above visual aid for members of Canada's Senate, since this is the week that they have a chance to pass a Bill that "aims to make it easier for Canada to export affordable, life-saving, generic medicines to developing countries." I wrote about this Bill C-393 earlier, stating how the right choice (passing the bill and not killing the bill) is obvious. But then it occurred to me that if the decision was so obvious, then why is there so much "push back" from the pharmaceutical industry (as well as the Harper government). It turns out the reason appears to be about Bill C-393 representing a trend that "could potentially" lead to a loss of control over the status quo. This being the status quo that provides the pharmaceutical industry with an inordinate amount of lobbying power to set prices; a business model that values huge profits above innovation; and something that they are so focused on protecting that even the smallest of losses must be avoided no matter the consequences. Which is simply reprehensible - because with this Bill, the consequences are not just about patent control: it's about the livelihood of millions of people, where the decision to "kill" or "not kill" the Bill could literally be a matter of life or death.

Pakistani Actress Veena Malik schools a mullah about Islam

Posted: 21 Mar 2011 12:15 PM PDT

[Video Link] Veena Malik is a Pakistani actress who appeared on the very popular Indian TV show Bigg Boss (the Indian version of Big Brother). In the clip above, a mullah tells her she brought shame on Pakistan with her behavior on the show, and that 100% of Pakistanis agree with him. The mullah also admits he didn't watch the show himself, but knows all of this to be true.

Veena responds by pretty much mopping up the floor with him. She points out out how her religion backs up her actions, where he's in violation of the same rules he's taking her to task for. She also says if he wishes to defend Islam, there are countless targets more deserving of close inspection, but here he is instead wasting his time complaining about an actress.

It's fantastic. The world needs to see more of this. Go Veena!

Lunnaya Raduga: 1984 Russian science fiction film

Posted: 21 Mar 2011 10:45 AM PDT


Strange Attractor's Mark Pilkington pointed me toward this enticing taste of Lunnaya Raduga (Лунная радуга), a 1984 Russian science fiction that looks terrific! Here's a description from AllMovie:

In this watchable sci fi story based on a novel by Sergei Pavlov, the time is the 21st century, and the space security organization has a dangerous situation on its hands -- it seems four individuals from outer space have the ability to change form and to affect radio transmissions and magnetic fields. Their powers could threaten governments on earth and seem to derive from an unusual accident on one of the moons of Uranus shortly after four astronauts landed. Now the space police have to bring this potentially disastrous situation under control.


How to: Make a hamantaschen Sierpinski triangle

Posted: 21 Mar 2011 10:39 AM PDT

YUMcookie.jpg

Seattle local food blogger Deborah Gardner has made something truly amazing—combining the delicious Jewish traditional filled cookies called hamantaschen with wondrous math geekery.

It's Purim, so I'm making the hamantaschen recipe my grandmother z"l developed while she was alive, and passed down to me. It's my family obligation to make this recipe now every year and send hamantaschen out in boxes (gifts called mishloach manot) to my family and dear ones. I've done my best to preserve this recipe; I've written it up in the New York Times, I've taught workshops on how to make it for two Purims in a row, and I've committed to the family hamantaschen-baking role.

But this year, I did something else. You may be familiar with the Sierpinski triangle, a mathematically attractive, self-repeating fractal that starts with one equilateral triangle and breaks down into ever-smaller triangles.

Somehow this year it dawned on me that the world was incomplete without a Sierpinski hamantaschen, or sierpinskitaschen. I scoured the vast reaches of the Interwebs, to see if this had been done before. I may have missed something, but it seems this has not.

Until today.

Instructions (and some neat Sierpinsky Triangle facts) can be found at the Seattle Local Food blog.

DIY video event in San Francisco: fair use, mashups, spoofs, Mozilla, and videoblogs

Posted: 21 Mar 2011 12:11 AM PDT

A free upcoming symposium in San Francisco in April, "24/7 2011: The State of the Art in DIY Video," looks like a hell of a good time. Jason "Lawgeek" Schultz mentions, "We have Mozilla doing a DIY Video Workshop to show off their new popcorn.js metadata interface and Jen Urban and I are running a DIY Fair Use workshop too, all before the main event."
The theme of the 2011 show is "collective action," as videomakers reach out to others, creating active communities in dialogue. The program includes examples from the most prominent forms of amateur video production:

* lip dubs, in which students craft single-shot music video portraits of their schools;
* brilliant auto-tune spoofs that transform quotidian and ridiculous moments captured on tape into sublime musical events;
* video remixes that are by turns overtly political and hilarious;
* videoblogs documenting everyday life and collective action around the world;
* fan vids, in which fans reimagine their icons through editing, sound design, and remix.

Curated collectively with input from Matteo Bittanti, Francesca Coppa, Sasha Costanza-Chock, Ryanne Hodson, Jonathan McIntosh, Tim Park, and Mike Wesch, who each made selections from different DIY genres, the final program includes dozens of examples in a fast-paced overview.

More mega-quakes: Coincidence, or cause-and-effect?

Posted: 21 Mar 2011 09:46 AM PDT

"What is clear is that for the 6.2 years since 2004, there have been more great earthquakes around the world than in any 6.2-year period throughout the 110-year history of seismic recordings," says Thorne Lay at the University of California, Santa Cruz. — from a New Scientist article about geologists attempting to find connections between the recent spate of mega-quakes. Important point: There simply may not be a connection. The number of mega-quakes is still so small that this really could just be a coincidence.

How earthquakes work—a nice video demonstration

Posted: 21 Mar 2011 09:38 AM PDT

In my chat with Jesse Bering for Bloggingheads, I tried to explain a little bit about why earthquakes happen at subduction zones, like the one near the coast of Japan. Lacking props, I used my hands to mock up the motion of one tectonic plate sliding beneath another. This video—made by science blogger Matt Kuchta—does a much better job of demonstrating the same thing. If you want to understand earthquakes a little better, I highly recommend reading the whole blog post that goes with this video.

What are the forces at work here? We have tectonic forces, pushing the pacific plate beneath the island arc of Japan. The weight of the island arc pushes against the subducting pacific plate and creates a resisting, friction force that opposes the tectonic force driving the plates. When all forces are equal, nothing moves. As long as the friction force opposes the tectonic force, the plates will not move. But eventually, the applied tectonic force exceeds the friction force, and the plates move. This movement shakes the crust and releases energy (seismic waves) that travels through the earth. The more sudden and longer the movement, the stronger the shaking/earthquake.

For our "Earthquake Machine," the friction is provided by the brick and the sandpaper. The tectonic force is applied by pulling on the string (which is attached to the spring). The spring transfers the tension to the brick. Once the "tectonic" force exceeds the friction force the brick will slip forward - but only a short distance. The friction causes the brick to slow down and the applied force drops. The spring accumulates some of the tension by deforming (strain), then the accumulated strain can be released. When the spring's force diminishes to that less than the friction force, the brick stops moving; it sticks. The strain on the spring increases again until another slip. This is often referred to stick-slip behavior and is why many active faults don't shake all the time.

This looks like a fun project to do with your kids! Kevin Kelly says:

My son Tywen and I made a toy wreath. First we cut a torus from a piece of scrap plywood. Then we hot glued on to it several bags of plastic toys from the dollar store. It was fun building up patterns. Time flowed quickly. It made us giggle at times. The thing is completely useless. But it evoked something vague when we hung it outside my studio door. It's pleasing in a strange way. Looks like art to me.
