The state that she governs has no income or sales tax. Instead, it imposes huge levies on the oil companies that lease its oil fields. The proceeds finance the government’s activities and enable it to issue a four-figure annual check to every man, woman, and child in the state. One of the reasons Palin has been a popular governor is that she added an extra twelve hundred dollars to this year’s check, bringing the per-person total to $3,269. A few weeks before she was nominated for Vice-President, she told a visiting journalist—Philip Gourevitch, of this magazine—that “we’re set up, unlike other states in the union, where it’s collectively Alaskans own the resources. So we share in the wealth when the development of these resources occurs.” Perhaps there is some meaningful distinction between spreading the wealth and sharing it (“collectively,” no less), but finding it would require the analytic skills of Karl the Marxist.Like, Socialism

Today at Boing Boing Gadgets, we worshipped the Pantone Rubik's cube and welcomed guest reviewer Alan Graham of Treehugger, who took a look at a new home music system from Sonos.
John found a rainbow keyboard, a review of Guitar Hero: World Tour, and the rumored motherboard for the rumored Mac Mini II. He thought the Gameboy theme for iPhone was fantastic, and 3-inch figurine speakers, too.
He liked liquid bookmarks, saw an icky transparent mouse with an insect in it, depressurized his head with the Ear Pressure Equalizer, and pronounced the final death for VCR.
Rob offered more on Lutec's inelegant perpetual motion machine, listened to unpleasant feedback music, and liked the look of UltraPin virtual pinball. He didn't think much of Blu-ray firmware upgrade nonsense or the stylings of Dell's new Optiplexes. Nor did he drop his cellphone down the toilet and get his arm stuck trying to fish it out.
Joel had an exclusive on Windows 7 screenshots that lasted about 40 seconds. Finally, there was a sinister science poster and the footage rotoscoped for Jordan Mechner's original Prince of Persia.
Modd3d has created a MIDI driven Halloween centerpiece of awesomeness -
I ripped the brains out of one of those cheap Gemmy skulls with the moving mouth and glowy eyes and installed a Midify board. It was a fairly easy project and I now have full control over the mouth and eyes. Now I just have to work on its musical taste.Personally, I think the skull's musical selection is spot-on.

One of my favorite things about Maker Faire is watching people make things. There are so many things to see and so many distractions - it's really cool to slow down and watch folks really focusing on the thing they're doing. Here's a little round-up of makers, both kids and grownups, making masks, metal-working, playing with LEGO, running virtual mazes, playing pong - lots more!


Over at the MightyOhm, Jeff has been working on building a streaming WiFi radio system (built around a Asus WL-520GU router):
I have been wanting to build a streaming radio for some time. I frequently work in my garage, where I occasionally use my Macbook to play music through a small amplifier and bookshelf speakers. The problem is that my laptop is not always set up in the garage, and greasy fingers are not a good thing to have around a white laptop, period. I could simply buy an internet radio, but I couldn't stomach the $150-$300 price tag on most players for such a luxury.So I decided to build one instead.
I started the design process by drafting an outline of desired features, and then breaking them down into wants and needs, while trying to keep the project scope under control.
Here's Part 1 of the project.
And Part 2.

For this weekend's Steam Powered: The California Steampunk Convention, the band Abney Park and Airship Ventures have teamed up to offer dirigible rides to conference-goers (for $785 a ticket). Airship Ventures just brought one of their Zeppelin NTs over from Germany and it will be moored at Moffett Field. MAKE contributor Todd Lappin was lucky enough to get a ride on the ship and posted a flight report on Telstar Logistics:
Operated by a startup called Airship Ventures, the Zeppelin NT will be based out of Moffett Field, Calfornia -- a fitting home, as Moffett was built by the US Navy during the 1920s to serve as a base for military dirigibles.The new Zeppelins are filled with the inert helium instead of highly flammable hydrogen, they're only about one-quarter the size of the old giants, and they're equipped with modern technology and avionics. Power is delivered by three Lycoming engines that put out around 200 horsepower each, and the airship frame is constructed from a combination of of aluminum and carbon fiber.

Up Ship! (Airship Ventures' blog, with a travelogue of their transatlantic and cross-country trip)
I just bought a new MacBook Pro. I like it. I was stunned at how bright the LED screen is. Then I realized it was only at half brightness. I don't mind the lack of a button under the trackpad. I pretend there's still a button under the trackpad. I rest my thumb where the button used to be. I'm OK with that, and it works for me.
I'm impressed with the precision of the casing. I picture dudes in white lab coats with metal instruments in their hands when I look at the tiny micro speaker holes. I don't remember picturing dudes in white lab coats before (OK maybe with the 1st gen iPhone). I'm surprised that it's not all that much thinner or lighter than the previous model though.
I like that, when lifting up the lid, the entire machine doesn't lift off the desk or try and skate away. I like that there's no latch, but miss an audible click that confirms it's fully closed. I like that all the inputs are on one side now. I don't like that it's the opposite side that I've configured my desk for.
I love the glass screen. I'll still need to plug into a non-glossy screen for any real color work. I've been OK with that. I think the speakers are louder than the previous model. I doubt my hearing has improved over the last few days, but if it has, then the speaker volume remains the same as the previous model. I'd be OK with that.
I was shocked how small the box it comes in is. I'm happy that Apple is considering packaging waste now. This reduced packaging lowers the "unboxing excitement" by approximately 4%. I'm OK with that.
I like this new MacBook Pro.

Elfdoll: Don't Call It A Toy Company“We think that we are not a doll company, we are artists,” says Elfdoll Foreign Trade Manager Yeounjoo Lim, best known to her customers and friends as Ms. Cholong...
Ms. Cholong’s job is part curator, part community organizer and part salesperson, bringing together BJD enthusiasts for events where purchasing the handmade objects is only part of the fun. At the showroom’s October 25 party, hobbyists arrived with arms filled with pieces from their own collections reconfigured to fit Halloween images of comic book heroes, steampunks, fairies, Japanese-styled Lolitas and goth boys in drag...
“Other companies, when they market the dolls, they actually create characters for them,” says Chris Holz of Melbourne, Australia, a collector who happened to arrive in Los Angeles just in time for this event. “The Elfdolls don’t have a background. They’ve got a name, but that’s tantamount to just identifying the doll. When people buy them, it’s whatever they want.”

Boing Boing pal Todd Lappin took a preview ride in the Airship Ventures craft that will be debuting on Halloween in the Bay Area (see previous BB post about that). Here's a snip from Todd's account:
Operated by a startup called Airship Ventures, the Zeppelin NT will be based out of Moffett Field, Calfornia -- a fitting home, as Moffett was built by the US Navy during the 1920s to serve as a base for military dirigibles.Flight Report: Aloft in a Zeppelin Airship (Telstar Logistics)The new Zeppelins are filled with the inert helium instead of highly flammable hydrogen, they're only about one-quarter the size of than the old giants, and they're equipped with modern technology and avionics.

Boarding an airship is not at all like boarding a conventional aircraft, because an airship doesn't sit still; it tends to bob and sway as the wind blows the big balloon around. As a result, climbing on board the Zeppelin is a bit like stepping from a stable dock onto a boat that's rocking on a gentle sea.

Sarah Palin has been unsurprising in her criticisms of Barack Obama's credentials and policies, fulfilling the traditional role of the vice presidential candidate being the most aggressive and pointed rhetorical attacker in a campaign. But a closer look at her deliberate use of vernacular and language reveals that she has gone far beyond any other candidate in vice presidential history in the dangerous and irresponsible implications of her attacks. She has phrased her attacks on Obama in a way that avoids accountability to the press while specifically addressing the subset of her audience who are most likely to advocate extreme actions against Obama.What Sarah Palin is Saying (dashes.com)I don't usually write about politics here; I leave the ugliness to those who seem to revel in it. But I think a lot about language, usually in a more lighthearted context like talking about yo mama jokes or lolcats. What's striking to me this election season, though, is that Sarah Palin has chosen to abuse her command of language so obviously without suffering any serious criticism for it thus far.
The crux of the issue is simple:
(1) Sarah Palin has unequivocally associated Barack Obama with the idea of terrorism and specifically with "terrorists".(2) Republican President George Bush has defined in our National Security Strategy, and the Republican Party's platform affirms, that we may identify and strike at terrorists before they have committed any defined acts of aggression against American citizens.
(3) George Bush has made clear, by stating before a joint session of Congress that "Either you are with us, or you are with the terrorists."
(4) Palin has used deliberate choice of language to avoid these connections being highlighted by the media, while increasing the likelihood that the target audience for her message will be incited by her statements.
Through these arguments, it becomes clear that Sarah Palin's assertions are designed not to prove that Obama is unqualified for the office of the Presidency of the United States. Rather, she appears to be attempting to convince a substantial portion of her supporters that Obama supports terrorism against the United States and thus should be, at the very least, incarcerated as an enemy combatant (which we are doing to American citizens already) or at worst, assassinated for supporting terror. She has done this knowing full well that she can retain plausible deniability thanks to the ambiguity of her statements as they'll be interpreted by the media, by her detractors, and by her more reasonable supporters.

The great writers' guide to DIY - Features, Books - The Independent via RW.
In his book Kafka's Soup, Mark Crick parodied literary giants by imagining how their their best-known characters would cook. Now, in Sartre's Sink, he's got them tackling home improvements...Hanging wallpaper with Ernest Hemingway
Tools: Pasting brush, Wallpaper brush, Decorator's scissors, Pasting table, Plumb line
Materials: Wallpaper, Wallpaper paste
The old man had worked for two days and two nights to strip away the old wallpaper and now on the morning of the third day the time to hang the new paper had come and he was tired. His palms were blistered from long hours scraping away the old paper and the blisters had begun to weep. The old man felt the pain in his hands as he looked again at the bare walls of the room. "Room, thou art big. But I will finish this trabajo that I have begun," he said. "Or I will die trying."
For too long DIY books have suffered the neglect of the literary Establishment. Finally, here in one volume, are the essential DIY tips of the world's greatest writers. Dostoyevsky tells of a young man employed by an elderly lady to retile her bathroom; Caesar puts up a shelf for his rebellious tribe of adolescenti; the existentialist hero of the Sartre pastiche is both disgusted and nauseated to discover in a blocked sink the revelation of his own condition. We also learn how to repair a dripping tap under Conrad's eyes, replace a window pane with a voyeuristic Milan Kundera, and hang wallpaper under the watchful eye of Mark Twain. Other handy hints include how to: replace a roof tile; remedy a squeaking floor board; remove a carpet stain and bleed a radiator, by writers, including Bronte, Shakespeare, Duras, Salinger and Paul Auster. As in "Kafka's Soup", each piece is illustrated by a famous artist, including da Vinci, Hokusai and Rembrandt.

"These individuals probably ingested harmine in therapeutic or medicinal practices, some maybe related to pregnancy and childbirth," said study co-author Juan Pablo Ogalde, a chemical archaeologist at the University of Tarapacá in Arica, Chile.Drugs Found In Hair of Ancient Andean Mummies
"However, it is possible also that consumption of harmine was involved in religious rituals, said Ogalde, whose research appeared online October 14 in the Journal of Archaeological Science.
X-rays showed that the adult male—who was buried with items of social prestige such as panpipes, a four-pointed hat, and a snuffing tray—had damage near the nose, perhaps from sniffing.
As for the baby, Ogalde speculated that the mother had consumed the drug and passed it on to her offspring during pregnancy or breast-feeding.
"The fact this mind-altering substance was found even with a one-year-old shows how much a part of their life it was," said archaeologist Alexei Vranich of the University of California, Los Angeles, who did not participate in the study.
That's the corporate code of conduct on free speech and privacy I've been talking about in generalities for quite some time. By midnight Tuesday U.S. East Coast time, the full set of documents and list of initial signatories will be made publicly available at globalnetworkinitiative.org.Link to her piece on rconversation.blogs.com.
On that website you'll be able to read the full text of the Principles on free expression and privacy. A group of companies, human rights organizations, socially responsible investment funds, academics, and free speech groups spent the last two-plus years reaching agreement on what should go into that document. There will also be a Governance Charter and a set of Implementation Guidelines giving more detail on how companies should adhere to the core principles. There will be an FAQ, list of participants, and contact people for the organizations that have joined the Global Network Initiative so far. The hope is that many more companies, NGOs, investment funds, and academic institutions around the world will join in the coming months.
The initial plan was to release the news so that the first news reports about the initiative would come out closer to the website's unveiling at 12:01am Wednesday EDT or 12:01pm HKT. But the story leaked early and the San Francisco Chronicle reported it on Monday without any comment from the participants who had all agreed not to talk until the official launch. Since then, the New York Times, Wall Street Journal, WSJ China Blog, the AP, AFP and others have reported the story with remarks from some of the participants. We can expect more coverage in the next 24 hours.
A few people have called me asking "does this thing have any teeth" or "is this thing more than just a figleaf for companies to get congress off their backs?"
Organizations like Human Rights Watch, Human Rights in China, Human Rights First, and the Committee to Protect Journalists would not be putting their reputations behind this thing if they didn't think it was meaningful.

It's Tuesday again! This week I am making a scary pumpkin. Nothing gory or disgusting, just something that will scare the kiddies and hopefully score me some candy. How? Well, I am glad you asked. I rummaged through my parts bins and came up with an idea. What if I connected a horn to an Arduino and let out a nice blast when someone came around trick-or-treating. Hopefully they are so scared they drop their bag-o-candy and run away, leaving me with plenty of treats.
Note: It's a joke people! No, I am not taking candy from kids (other than my own). Have fun, and be nice!
What you need:
Tools you need:
Step 1: Cut up the pumpkin
You can use a real pumpkin, but I picked this one up for $5 at a local craft store. Using a real one is fine, but photographing it over a few days can get messy so I decided to use a foam version.
The foam pumpkins are really easy to carve. So far it looks like a classic, smiling, jack-o-lantern. The kids will never suspect anything.
Step 2: Add the nose button
I had an arcade game button, so I used it for the nose, and a old doorbell button I used to trigger the horn. You can use any button that you have in your scrap bin.
Solder some wires to the "nose button" so you can assemble the electronics outside the pumpkin. Attach one wire to the ground of the Arduino and the other wire to pin (7). Also, you need an additional wire with a 10K resistor to ground. (See step 3 for a simple diagram) Speaking of Halloween, that is some scary soldering! Yuck.

It's made of meat, all of it... @ The Daneyal Mahmood Gallery....
Meat After Meat Joy brings together the work of contemporary artists who use meat in their work (raw meat, the concept of meat, its symbolism and viscera) in order to investigate the paradoxical relationship meat has to the body. Meat combines flesh, skin, muscle, organs, blood — each with its own relationship to the body, yet meat’s only reference to the body is as a once-upon-a-time living biological thing. By putting these artists together, the exhibition seeks to investigate the uncanny effect meat as a medium is for artist and viewer. This is not a show about meat as spectacle but about meat as signification, precisely because meat does not signify (a body) but its very annihilationRead more | Permalink | Comments | Read more articles in Arts | Digg this!

"Resting inside the crystal ball is the ghoulish disembodied head of Madame Leota, the house's resident medium. Her hair is long and white, uncombed, her face a ghoulish yellow-green, and she looks around the room and moves her entire face in a rather animated way (for a ghost at least!) "

These in-guitar effects kits look interesting -
The MODboard concept is simple- Take the best vintage style analog guitar effects, miniaturize them, and mount them on a completely modular circuit board. Add the right output jack, knob setup and switching setup to accomodate your guitar, and you're ready to roll. A few simple solder connections for input and power, then everything plugs in with instantly removable modular connectors.Offered in tremolo, wah, compressor, delay, chorus, and tube distortion flavors. While the "best vintage style" description is of course very subjective, the concept seems sound[npi]. Glancing down toward ones feet during a dimly lit gig is never fun - moving at least your most important effect's controls onto the instrument body sounds like a smart idea. Any music-makers out there ever used these? Or have any good tips for mounting your own effects 'in-instrument'? - MODboards
Of course, one could always just duct tape a pedal to their axe a la DEVO -

Sidni writes -
Dr. Aaron Lanterman of Georgia Tech covers the analysis of several modules used in analog modular synthesis as well as digital synthesis techniques. All lectures posted online for free!Definitely a class that would've greatly increased my interest in math back in school - very cool!
Moog (east coast) and Buchla (west coat) developed their ideas about voltage controlled synthesizers independently. Moog used a pitch control standof of 1 volt/octave, which works out to 0.08333... volts/semitone (the pitch difference between to adjacent notes on the piano is a semitone; there are twelve semitones per octave). Buchla preferred to use 0.1 volts/semitone, which works out to 1.2 volts/octave.Hence, if to try to directly drive a Moog oscillator from a Buchla pitch control source, or vice-versa, everything will be horribly out of tune.
a) Design an circuit with a single op amp that will covert pitch control voltages from the Moog standard to the Buchla standard. You may assume that your conversion module is given an input from a voltage source with zero output impedance and is being fed to a module with an infinite input impedance; you also do not need worry about input and output protection (assume nobody will be abusing your module). For this part of the exercise, assume you have perfect "zero-tolerance" resistors.
b) Off-the-shelf resistors never exactly match their listed values. Let's do a "worst case" analysis for the case where your circuit is given a one volt input. If you use 5% resistors, assuming the true resistance is uniformly distributed, what is the highest voltage you might get out? What is the lowest voltage? How many semitones above and below the desired value are these voltages in the Buchla pitch standard?
c) Repeat the above analysis for 1% resistors.

The KNFB Reader lets users photograph printed material, then reads it back... The possibilities of a 'portable eye' - The Boston Globe.
When Peter Alan Smith pulls out his phone in a crowded Back Bay restaurant, there's no clue that his Nokia is by far the most expensive mobile phone in the entire place. He has about $2,400 in software loaded onto the $600 device.
But then it becomes apparent what's unique about Smith's phone: A flash goes off when he snaps a picture of the menu, and a few seconds later, his phone has translated the page of text into speech, and started reciting the options through his earpiece at a rapid clip.
Smith developed a degenerative eye disease when he was 18, and he is now legally blind. It has been about two decades since he could read a restaurant menu independently. He first heard about the phone on a podcast series called "Blind Cool Tech" and took out a low-interest loan to buy it.

Charlie Chaplin, you may have met your match. His name is Matt Mets, and he wears a noisy hat:
The inspiration for this project came while on the long road trip to Austin last weekend, and I finally had some time to make it. The prototype is a bit rough, but I think it gets the point across well enough. Walkthrough of the project and schematic after the break.
I started off with a 555 timer VCO circuit that I found at ecelab.com. Next, I hooked up a Sharp GP2D120 infrared distance sensor that I had laying around from another project, and added a cheap level shifter to allow the sensor to control the oscillation frequency of the 555 timer. Once that was basically working, I played around with the potentiometers until I had a range of sounds that seemed reasonable.
Finally, I put the module together with a battery, speaker and (momentary) on switch, and Velcroed each piece to the (except the switch) inside of my hat. I cut a small slit in the side of that, ran the wires for the switch through that, and then stuck the switch under one of the side curls on the outside. This way, you can start playing music by picking up the hat as you normally would, but also catching the switch in the same motion.
Insiders Tip: Don't take this to the airport.
Schematic included!

Arrests in Plan to Kill Obama and Black Schoolchildren (New York Times).The assassination was to be the culmination of a “killing spree” that would also single out children at an unnamed, predominately black school, federal officials said. The men talked of “killing 88 people and beheading 14 African-Americans,” according to the affidavit.
The two men each had “very strong views” about Aryan white power and “skinhead” ideology, the federal officials said, and the numbers 88 and 14 have special significance in the white power movement. The number 88 is shorthand for “Heil Hitler” — H is the eighth letter in the alphabet —and 14 signifies a 14-word mantra among white supremacists: “We must secure the existence of our people and a future for white children.”
Officials said the two men met via the Internet through a mutual friend.
Smoking Gun has a copy of the ATF affadavit, which reveals that the fashion-conscious FAIL duo planned to wear white tuxedoes and top hats to the massacre.
