Pornoscanners trivially defeated by pancake-shaped explosives Posted: 11 Dec 2010 11:43 PM PST In case you were wondering whether pornoscanners are harder on the vast majority of innocent, non-terrorist fliers, or the minuscule minority of terrorists, wonder no more. From Leon Kaufman and Joseph W. Carlson's "An evaluation of airport x-ray backscatter units based on image characteristics," published in the Journal of Transportation Security: The penetration not only distributes exposure throughout the body (this affecting the calculation of effective dose, which comprises a sum over all organs), but tends to diffuse the effects caused by contraband materials. Images can be made at low entrance exposures, but of very poor spatial resolution and S/N. The calculated signal excursions at high kilovoltage are so small as to make it doubtful that at any reasonable exposure levels density differences will be noticeable unless the contraband is packed thickly and with hard edges. Although the excursions are larger at low kilovoltage, they are still small and in the noise of the device's operational limits. The eye is a good signal averager at certain spatial frequencies, but it is doubtful that an operator can be trained to detect these differences unless the material is hard-edged, not too large and regular- shaped. Anatomic features and benign objects add structured noise that interferes with signal averaging. Figure 18 shows a widely-distributed backscatter image. On the left is a complete view of her torso, on the right, a section has been blacked out. While the breasts are easily recognized at right, without some prior knowledge of the subject, it would be hard to distinguish the increase of intensity in the superior part of her breasts from the natural gradients of the image.An evaluation of airport x-ray backscatter units based on image characteristics (PDF) (via /.)

Kids' book/science fiction mashups Posted: 11 Dec 2010 11:34 PM PST From College Humor, a small but well-made collection of science fiction kids' classic mashup covers. Five Sci-Fi Children's Books (Thanks, Hughelectronic, via Submitterator) |
Posted: 11 Dec 2010 08:32 PM PST The long-awaited Collateral Murder (2010) was released soon after and benefited from authentic, muscular riffs and a tortured atonality which highlighted its more aggressive sound. And yet the production's energy, while benefiting from Sugarcubes-esque rhythm work, offers a starkness often at odds with haunting melodies that remain fastidiously progressive in their length and (some contend) lack of clarity. The most exciting moments are, indeed, easy to miss, though the dark melancholy of the album as a whole is unavoidable. A tour de force, it vanquished memories of earnest but anemic efforts such as 2009's Trafigura and 2008's The Secret Bibles, which recalls Sting at his most superfluous. Nevertheless, few predicted Assange's stunning follow-up later in 2010, which would unite him with legendary proto-punk axeman Ellsberg and return him to the heights of 2006's seminal Julius Baer's Cayman Islands Banking Adventure. His status as this generation's Astley would be secured; but at what cost? Astley-Assange illo by @exiledsurfer via Artificial Eyes. Original Bonus Track by Ding.net. |
It's a blizzard. Grab your bike. Posted: 11 Dec 2010 03:31 PM PST It's now mostly stopped snowing, at least in my corner of Minneapolis. Depending on where you measure, somewhere between 14 and 20 inches of snow fell here today. And it's still blowing around. So, naturally, this was a perfect day to travel by bicycle. After all, our estimated 4,000 winter bike commuters are the reason Bicycle magazine named Minneapolis the #1 bike city in America. Cheers to you, winter cyclists. That said, I hope most of you weren't out in this mess today. Photo taken by Christopher Baker. |
Obituary for John Dawkins, father of Richard Dawkins Posted: 11 Dec 2010 03:35 PM PST We were saddened to learn this week that Richard Dawkins' father passed away. All of us at Boing Boing extend our condolences to the Dawkins family. From a remembrance by Richard Dawkins: My father, (Clinton) John Dawkins, who has died peacefully of old age, packed an enormous amount into his 95 years.

Vladimir Putin sings Blueberry Hill Posted: 11 Dec 2010 03:23 PM PST |
Posted: 11 Dec 2010 01:47 PM PST If politics in America means nasty, lurid analysis of a cancer victim's "evasion" of mentioning God in her public farewell, politics in America deserves a thousand Julian Assanges. |
Posted: 11 Dec 2010 11:52 AM PST Did anybody catch Mercury for the first time last night? I had just enough hazy cloud on my western horizon last night that Mercury was lost in the much. If you missed it, keep trying. And if you still can't find it, don't fret: your assignment for tonight is much, much easier. The planets all travel around the sun in flat disk. Since we sit inside this disk too, when we go outside and look for planets they will all lie along one giant circle around us. Planets move slowly, so waiting for one of them to trace out the giant circle can take a while, but the Moon takes only a month to circle around us, so we can use it to trace the paths of the planets in the sky. If you've been watching the moon the last few days, you have seen it climbing in the evening sky still growing towards its first quarter (which comes up on Monday - so quickly! Wasn't it a tiny sliver just days ago?). The earthshine is fading away, as the view of the Earth from the Moon is also moving from full to third quarter.
As the moon has moved eastward, it might have been hard for you not to notice the incredibly bright star that the moon has been getting closer and closer to. It will be at its very closest on Monday night. That star is a great marker for helping you really visualize how fast the moon is moving across the sky. On Monday night, if you look right and sunset and then again a few hours later, you will even be able to notice the different positions in a single night.
On the left, close together are the oddly magnetic Ganymede and the icy ocean filled Europa, close on the right is Io, the most volcanically active place in the solar system, and furthest of all on the right is Callisto, which is, well, just Callisto.

Posted: 11 Dec 2010 09:51 AM PST It's snowing in Minnesota, today. A lot. About an hour ago, I took the trash out, and came back to the house with a snow line around my knees. And it's still coming down. That's all fine, though. What I'm really dreading is tomorrow, when I have to shovel it all up. Increasingly, I find my fancy turned toward the wovel—a ridiculous-looking piece of hand-powered machinery, that's supposed to help you clear a sidewalk easily, without the lower back pain*. I'm intrigued, and may have to end up buying and reviewing one of these things later this winter. In the meantime, do any of you own one? Is it as fabulous as they say? It came out in 2005 and has since inspired a ton of YouTube fan videos. I chose this one because the guy is woveling in shorts, for some reason. *I've already decided that a gas-powered snow blower isn't an option. A) I just don't feel like owning yet another fossil-fuel burning contraption. B) I live on a hill in the middle of a block and am equally uninterested in hauling a snow blower up and down the slope. |
Anonymous isn't: LOIC leaks internet address of user Posted: 11 Dec 2010 07:40 AM PST Researchers at the University of Twente in the Netherlands report that the LOIC (Low Orbit Ion Cannon) software used in pro-Wikileaks Anonymous attacks discloses the identity of the user. If hacktivists use this tool directly from their own machines, instead of via anonymization networks such as Tor, the Internet address of the attacker is included in every Internet message being transmitted. In the tools no sophisticated techniques are used, such as IP-spoofing, in which the source address of others is used, or reflected attacks, in which attacks go via third party systems. The current attack technique can therefore be compared to overwhelming someone with letters, but putting your address at the back of the envelop. In addition, hacktivists may not be aware that international data retention laws require that commercial Internet providers store data regarding Internet usage for at least 6 months. This means that hacktivists can still be traced easily after the attacks are over.Here's a PDF with details on the report.

The CIA honeypot Wikileaks mirror that wasn't Posted: 11 Dec 2010 07:47 AM PST Yesterday, I posted an item referencing a reddit thread and a widely-retweeted Google search string referencing a purported "CIA wikileaks mirror honeypot" that revealed itself as likely having been set up by the CIA. It wasn't. It was some guy's joke or something. I'm traveling with wonky mobile internet, and in the process of attempting to update the post with a clarification late last night in a sleep-depped state, I screwed up. The post was deleted. There is no conspiracy here, and no reason to believe the CIA is setting up fake Wikileaks mirrors (though, not a bad idea, amirite?). However, I can tell you this, no joke: I'm traveling in Texas, in an area with a high Muslim population. Last night, I saw ads on the hotel TV for the CIA. Clandestine services recruitment ads. I googled around, and apparently these are part of a broad campaign that began in 2009, to recruit more Arab-Americans. I can't find the actual ad I saw last night, but here are earlier examples from the same campaign. You may also want to fire up Tor, disable cookies, and take their personality quiz. No, neither of those have anything to do with a misleading Reddit thread, or me screwing up a blog post. But! The TV ads were so bad (even the aspect ratio was messed up), I thought, yeah, I could believe. |
