Pet Door with RFID

Spiegel calls this Pet Door 2.0

Ghip happens to know such precise details about his cats’ behavior because he has figured out how to make the world’s first photo-tweeting cat door. Penny and Gus both wear collars outfitted with thumb-nail-sized radio-frequency identification (RFID) chips. The chips are passively sensed, which means they don’t require a battery and don’t weigh down the collar. Whenever a cat goes near the door, a small RFID reader scans the tag and determines whether the cat is authorized to go in or out.

If the chip tells the reader that the cat is authorized, it not only activates the door opener; it simultaneously also activates a camera and a program on an attached laptop that sends the captured image to a separate Twitter account, where it is automatically posted on the cats’ microblog with a simple, cute caption that is automatically generated, such as “Gus is out to get rid of a hairball” or “Penny is in to shred the chair.”

Very nice. I first wrote about this idea in October 2005 on Bruce’s blog

Organic White House angers MACA

La Vida Locavore points out a pointed letter from the Mid America CropLife Association (MACA) to the First Lady:

Did you hear the news? The White House is planning to have an “organic” garden on the grounds to provide fresh fruits and vegetables for the Obama’s and their guests. While a garden is a great idea, the thought of it being organic made Janet Braun, CropLife Ambassador Coordinator and I shudder. As a result, we sent a letter encouraging them to consider using crop protection products and to recognize the importance of agriculture to the entire U.S. economy. Read below for the entire letter.

MACA practically begs the First Lady to stop being organic, but their argument strays far away from organic issues and across a vast plain of technology. They mention everything from soil erosion and infrared weed detectors to four-wheel-drive tractors and GPS-enabled pesticide sprayers. Last time I checked, using a four-wheel drive tractor with high horsepower does not make a garden less organic. Likewise an infrared detector is surely acceptable. So what’s their beef? The “War of the Weeds” presentation on the maca.org site has fun facts like these:

Q: How many teens would it take to replace herbicides?
A: 220 million acres = 4 acres per teenager = 55 million!

So each teenager could kill 4 acres of weed (pun not intended). Apparently that’s based on data from the 1950s in Minnesota and North Dakota, when a program was started to keep kids from getting into trouble. I wonder if anyone considered this when they drafted the stimulus package.

MACA also takes a couple shots at California for requesting a hand weeding exemption. They argue hoes are less dangerous to your back than using your hand (er, pun not intended) and they say California organic growers claimed crop and profit loss if they were unable to use hand weeding. In fact, they say “hand weeding more dangerous to back than short handled hoe”. If I remember correctly, California actually banned the short-handled hoe in 1975 and then all short-handled tools in 1978 after employers tried to get around the original ban by using things other than hoes such as knives. Then in 2004 California banned hand-weeding after a long debate on how to close the loop-hole left by the 1978 rules. The state thus established protection for farm workers from back-breaking work, but also allowed options for organic growers to weed manually. A quick check of the California Code of Regulations, Title 8, Section 3456. Hand-Held Tools gives details:

(b) The use of a short-handled hoe or any other short-handled hand tool is prohibited in agricultural operations, as that term is defined in Section 3437, for weeding, thinning or hot-capping when such hoe or short-handled hand tool is used in a stooped, kneeling or squatting position. A long-handled hand tool used for these operations shall not be used as a short-handled hand tool in a stooped, kneeling or squatting position.

(c)(1) Hand weeding, hand thinning, and hand hot-capping in a stooped, kneeling or squatting position shall not be permitted in agricultural operations as defined in Section 3437, unless there is no readily available, reasonable alternative means of performing the work that is suitable and appropriate to the production of the agricultural or horticultural commodity.

(2) Upon inquiry made by the Division of Occupational Safety and Health personnel, the employer shall bear the burden of justifying that the use of hand weeding, hand thinning, or hand hot-capping was required due to the unsuitability of the use of a long-handled tool or other alternative means of performing the work.

This says to me that short-handled or long-handled tools can not be used when they are used in an unhealthy position, and hands also may not be used unless there is no alternative method found. Employers have to demonstrate their requirements, but most will fall out of regulation if they use nurseries or systems with plants less than 2-inches apart. Thus the MACA presentation seems to paint a somewhat deceptive anti-organic picture, which goes right back to their rambling letter to the White House. It seems to me they would rather express a passion against changes to their world rather than any coherent or logical argument with facts relevant to the issue at hand (pun not intended).

Social Media Breeding Extreme Right Wing in America

Crooks and Liars provides an emerging portrait of Richard Poplawski: a white-supremacist radical

Thanks to some sleuth work on the Internet, we’re starting to learn more about Richard Poplawski, the 23-year-old who killed three police officers yesterday in Pittsburgh, evidently out of fear that his guns were going to be taken away.

It appears that what police may be looking at is a budding white supremacist who frequented one of the most popular neo-Nazi websites and harbored an apocalyptic dread of the federal government.

The Anti-Defamation League provides an in-depth review:

Following the Super Bowl victory of the Pittsburgh Steelers in early February 2009, Poplawski used the celebrations that occurred in Pittsburgh as an opportunity to “survey police procedure in an unrestful environment,” and reported the results of his reconnaissance to fellow Stormfronters. “It was just creepy seeing busses [sic] put into action by authorities, as if they were ready to transport busloads of Steeler fans to 645 FEMA drive if necessary.”

This last comment was a reference to popular right-wing conspiracy theories about Federal Emergency Management Agency (FEMA)-constructed prisons and concentration camps for U.S. citizens. Such conspiracy theories had long been staples of the militia movement, but received a reinvigorating shot in the arm following the election of Barack Obama as president. Almost overnight, right-wing conspiracists across the country revived all of their 1990s militia conspiracy theories about the “New World Order,” planned gun confiscations, and government plots against the citizenry. Once more, wild speculations about SHTF (“s–t hits the fan”) and TEOTWAKI (“the end of the world as we know it”) scenarios became rampant.

Although it is easy to get distracted by political affiliations (some bristle at the Missouri warning, which included third party bumper stickers as a clue) there are probably more clear indicators of unlawful and dangerous intent.

As early as November 2008, he inquired on a Pennsylvania firearms discussion forum about the legality of sawed off shotguns and mentioned that he had purchased body armor from a friend. In February, he posted to the same forum that “a group of friends and I are considering purchasing a lot of military surplus rifles.”

It is hard to process the situation and imagine what the two officers were thinking when they were invited by a woman to enter her home and confront her son, a violent and extreme right-wing youth with a troubled past including failure in military training.

Four months of online activity after November of 2008 indicate he was sliding from violent tendencies to paranoia and hatred.

By March 2009, Poplawski apparently felt himself at a crossroads of sorts. In his longest and most revealing post on Stormfront, Poplawski confirmed his belief that Jews controlled the U.S. government and his conviction that some sort of collapse of the “economic and social order” of the United States was inevitable, “poisoned by design by the moral decadence that is a direct byproduct of [Jewish control].”

The challenge is to identify these misguided and delusional threats and isolate them as individuals who need help, without restricting or scaring the groups they join that are itching for a reason to fight. That seems to be what the US DHS intended with their April 7th report, available here. From a historical perspective unemployed young men have always been an issue for countries in economic slump. The current American climate has veterans returning to no jobs while huge spending bills float through to special interests. The susceptibility of these young trained men to extremist groups is the topic, and the question is how to predict when rational, slow anger might be provoked into violent action and against whom. A January report by the DHS profiled the threat from left-wing extremists. Apparently both reports were initiated under the Bush administration.
