3D scanner made out of a webcam, Legos, and milk

Friedrich Kirschner has built a device to make 3D image scans of objects placed in a small plastic container, using a webcam and a platform built of Legos, and some milk.

September's Fall

Finally, we see a break in the past year's almost relentless upward trend in Maricopa County's Notices of Trustees Sales...

Click for Full Size
September's total was 2836 - well off from last month's high.

Something tells me, though, that this is not the start of a new trend downward, just yet.

Oh, I should note that I've changed the graph this month so that the vertical axis starts at zero instead of 400.

Liberty, security, and death

"Give me Liberty, or give me Death!"
--Patrick Henry, March 23, 1775

"Those who would give up essential liberty to purchase a little temporary safety, deserve neither liberty nor safety."
--Richard Jackson, motto on title page of An Historical Review of the Constitution and Government of Pennsylvania, 1759 (often attributed to its publisher, Benjamin Franklin)

"And I hear from time to time people say, hey, wait a second. We have civil liberties we have to worry about. But don't forget, the most important civil liberty I expect from my government is my right to be kept alive, and that's what we're going to have to do."
--Mitt Romney, Republican presidential candidate debate, September 5, 2007

Hacker finds vulnerability in Adobe Reader

A hacker has found a flaw in Adobe's PDF file format which can be used to exploit Adobe Reader 8.1 on Windows XP.

Dave G. at the Matasano Chargen blog predicts that such attacks--targeting popular applications--will become more common. PDF in particular is a likely target due to its ubiquity and its complexity.

Instructor fired for saying Adam and Eve story shouldn't be taken literally

In Red Oak, Iowa:
A community college instructor in Red Oak claims he was fired after he told his students that the biblical story of Adam and Eve should not be literally interpreted.

Steve Bitterman, 60, said officials at Southwestern Community College sided with a handful of students who threatened legal action over his remarks in a western civilization class Tuesday. He said he was fired Thursday.

"I'm just a little bit shocked myself that a college in good standing would back up students who insist that people who have been through college and have a master's degree, a couple actually, have to teach that there were such things as talking snakes or lose their job," Bitterman said.
...
Bitterman said he called the story of Adam and Eve a "fairy tale" in a conversation with a student after the class and was told the students had threatened to see an attorney. He declined to identify any of the students in the class.
Even most Christians on the planet don't think that the Adam and Eve story is literally true, so it's hard to see why this would even be a controversial statement in a western civilization class. The quotes in the article from the school suggest that Bitterman was fired for something else (a "personnel issue"), but the firing immediately following the class with the student threatening legal action seems to support his account.

Naomi Wolf on 10 steps to a fascist America

I just saw Naomi Wolf on The Colbert Report (Wednesday night's show), discussing her new book, The End of America: A Letter of Warning to a Young Patriot. She only had time to list a few of the ten steps on her list, but I found all ten in an article from the Guardian:

1. Invoke a terrifying internal and external enemy
2. Create a gulag
3. Develop a thug caste
4. Set up an internal surveillance system
5. Harass citizens' groups
6. Engage in arbitrary detention and release
7. Target key individuals
8. Control the press
9. Dissent equals treason
10. Suspend the rule of law

Boston police arrest MIT student for blinking nametag

Boston authorities have filed another set of bogus "hoax device" charges, against Star Simpson, a 19-year-old MIT student who was wearing a sweatshirt with a homemade electronic nametag stuck to the front of it. The device was made of a breadboard with LEDs and a 9V battery, and Simpson was also holding "a lump of putty" in her hands, as she was waiting at Logan airport for a friend's flight to arrive. She explained that she made the device for career day because she wanted to stand out. She was released on $750 bail and will have to appear in court on October 29 on charges of "possessing a hoax device."

The Boston Globe's article says:

Outside the terminal, Simpson was surrounded by police holding machine guns.

"She was immediately told to stop, to raise her hands, and not make any movement so we could observe all her movements to see if she was trying to trip any type of device," Pare said at a press conference at Logan. "There was obviously a concern that had she not followed the protocol ... we may have used deadly force."

Catch that last part--the police might have killed her for wearing an LED nametag.

AP and Information Week reported the device as a "fake bomb." It doesn't look at all like a fake bomb--if there was intent to do anything of the sort, I suspect it was to show how ridiculous the Boston authorities still are after the Mooninite scare. Would a jury decide that a reasonable person would think it was a bomb?

(Via Bruce Schneier's blog.)

UPDATE (September 21, 2007): I think this case is less absurd than the Mooninite one, where the devices were clearly professionally made to look like light-up cartoon characters. Questioning her was appropriate, but I don't think charging her was unless there is some evidence of intent to commit a hoax that hasn't yet been reported.

Bruce Schneier has previously reported a list of "terrorist dry run" items that TSA issued warnings about, in which each case actually had a valid explanation (though we still haven't seen what the explanation was for the "wire coil wrapped around a possible initiator, an electrical switch, batteries, three tubes and two blocks of cheese").

Odd, unexplained items are deserving of questioning and scrutiny, I think we can all agree.

UPDATE: Boing Boing has more details.

Who called the housing bubble and who didn't

It's interesting to look back at old blog posts and comments to see who correctly identified that we were in a housing bubble and who inaccurately denied it.

Jane Galt (Megan McArdle) at Asymmetrical Information called it correctly, way back in January 2004.

I called it in September 2004, suggesting a drop in "the next year or two." The peak for Phoenix was in the fourth quarter of 2006, so I was pretty close, but I expected the drop to come a bit earlier than it actually did.

Economist Tyler Cowan was still in denial in April 2005.

In the June 2005 issue of Business Week, Frank Nothaft of Freddie Mac and James F. Smith of the Society of Industrial and Office Realtors said that the housing bubble was bunk and they saw no possibility of national price declines in the future. Dean Baker of the Center for Economic and Policy Research called it a bubble. Mike Englund of Action Economics fell somewhere in between, saying that "It's bubble behavior" but "not clear that the recent price gains in the housing market are a bubble."

Economist Edward Stringham told me he didn't think there was a housing bubble in November 2005.

Economist Greg Mankiw hinted that he thought there was a bubble in June 2006.

In the Fall 2007 issue of USAA Magazine, just delivered to my home yesterday, an article titled "Real (Estate) page turners" quotes "The Apprentice: Season 3" winner Kendra Todd, author of Risk and Grow Rich: How to Make Millions in Real Estate:
Ms. Todd disagrees with those who say there has been a bust for real estate. "What's dropped in some areas is market expectations more than market values," she argues.
I think Ms. Todd should start working on her manuscript for Risk and Grow Poor: How to Lose Millions in Real Estate. Of course, I doubt she makes most of her income from real estate investing, rather than book sales and her hosting of HGTV's "My House Is Worth What?"

Republican San Diego mayor signs resolution for gay marriage

The Republican mayor of San Diego, Jerry Sanders, has signed a resolution supporting gay marriage, stating that:
"In order to be consistent with the position I took during the mayoral election, I intended to veto the council resolution. As late as yesterday afternoon, that was my position.

"The arrival of the resolution -- to sign or veto -- in my office late last night forced me to reflect and search my soul for the right thing to do.

"I have decided to lead with my heart, which is probably obvious at the moment -- to do what I think is right, and to take a stand on behalf of equality and social justice. The right thing for me to do is sign this resolution.

"For three decades, I have worked to bring enlightenment, justice and equality to all parts of our community.

"As I reflected on the choices I had before me last night, I just could not bring myself to tell an entire group of people in our community they were less important, less worthy or less deserving of the rights and responsibilities of marriage -- than anyone else -- simply because of their sexual orientation.

"A decision to veto this resolution would have been inconsistent with the values I have embraced over the past 30 years.

"I do believe that times have changed. And with changing time, and new life experiences, come different opinions. I think that's natural, and it's certainly true in my case.

"Two years ago, I believed that civil unions were a fair alternative. Those beliefs, in my case, have changed.

"The concept of a 'separate but equal' institution is not something I can support.

"I acknowledge that not all members of our community will agree or perhaps even understand my decision today.

"All I can offer them is that I am trying to do what I believe is right.

"I have close family members and friends who are a member of the gay and lesbian community. Those folks include my daughter Lisa, as well as members of my personal staff.

"I want for them the same thing that we all want for our loved ones -- for each of them to find a mate whom they love deeply and who loves them back; someone with whom they can grow old together and share life's experiences.

"And I want their relationships to be protected equally under the law. In the end, I couldn't look any of them in the face and tell them that their relationship -- their very lives -- were any less meaningful than the marriage I share with my wife Rana. Thank you."
