Diane and I completely unplugged this weekend so I'm spending the evening catching up. I'll have photos probably Tuesday, depending how crazy tomorrow goes for me. Meanwhile, a joke from one of my clients:

A noob used the following password: "MickeyMinniePlutoHueyLouieDeweyDonaldGoofySacramento" When asked why he had such a long password, he said he was told that it had to be at least 8 characters long and include at least one capital.

Core inflation defined

Paul Krugman has a review posting explaining the concept:

Core inflation isn’t supposed to measure the cost of living, it’s supposed to measure something else: inflation inertia.

Think about it this way. Some prices in the economy fluctuate all the time in the face of supply and demand; food and fuel are the obvious examples. Many prices, however, don’t fluctuate this way — they’re set by oligopolistic firms, or negotiated in long-term contracts, so they’re only revised at intervals ranging from months to years. Many wages are set the same way.

Why the review? Because we're becoming like more Japan in the 1990s:

[I]nflation tends to be self-perpetuating, unless there’s a big excess of either supply or demand. In particular, once expectations of, say, persistent 10 percent inflation have become “embedded” in the economy, it will take a major period of slack — years of high unemployment — to get that rate down. Case in point: the extremely expensive disinflation of the early 1980s.

...And what these measures show is an ongoing process of disinflation that could, in not too long, turn into outright deflation.

It's not quite end-of-the-world stuff, but it does make one nervous.

Where can I get some?

Chicago Public Radio's David Hammond investigated raw-milk cheese, which is illegal to sell in Illinois:

HAMMOND: ...[W]e got together with a group of chefs and other food enthusiasts in Itasca at a wine bar called Wine with Me to sample both raw and pasteurized milk versions of camembert. No money changes hands, and we’re all consenting adults, so technically there’s no illegal activity taking place. Sitting around a big wooden table, we’re confronted by two very different looking cheeses. As part of this taste test, neither cheese was labeled, but the differences were very apparent. One cheese was rigid and uniform; the other was collapsing in on itself. We started by putting our noses into the stuff. Gary Wiviott is a Chicago food writer and author.

WIVIOTT: Of the two cheeses, one has a distinct ammonia smell and the other smells funky, earthy, almost a little mushroom-y, like a damp forest on a fall day, when the leaves are just starting to break down, very appealing, a very appealing aroma. And the other has a less appealing aroma…I just want to dive into the softer, slightly gooey looking one. I just want to take a big bite out of the darn thing.

Is there a black market for raw-milk cheese in Illinois? Or do I have to go to France to get some?

What is the capital of Estonia?

The Tribune today has a guide to pub trivia in Chicago.

With my nights free and my dog in another time zone (i.e., no need to rush home and walk him after work), I will try some of them. Any other recommendations?

Answer: Tallinn.

Sad to see it go

The epitome of overcompensating excess and planetary rape will soon fade away into memory:

The sale of the [Hummer] SUV brand with military roots to a Chinese heavy equipment maker has collapsed. GM said it would still hear offers for the company, but potential investors would have to move fast.

GM said Wednesday that its bid to sell Hummer to Sichuan Tengzhong Heavy Industrial Machines Co. fell through. The Chinese manufacturer said it failed to get clearance from regulators in Beijing within the proposed timeframe for the sale.

GM will continue to honor warranties for current Hummer owners.

One wonders what short, angry men will drive instead? I guess there's always the Escalade, or possibly the good ol' John Deere 9030.

There's one other consequence of this...

El Niño hace la nieva

A winter storm off the coast of North Carolina has brought snow to both Chicago and Raleigh:

25 mm of snow had fallen at O'Hare by 8:30 p.m. Wednesday, with snow still coming down hard. That was enough to push the city's official seasonal snow tally above 127 cm for the third consecutive year. There's been only one other string of three consecutive 50+ inch seasons in 125 years of snow measurements here and it occurred between 1976 to 1979.

In North Carolina the snow is causing the same kinds of disruptions as in Chicago—slow traffic, nervous parents, confused dogs—but...well, it's not quite as much snow:

Stupefying

If this story is true, someone needs time in jail to think about civic responsibility:

In a lawsuit filed Tuesday in federal court, [a Pennsylvania] family said the school's assistant principal had confronted their son, told him he had "engaged in improper behavior in [his] home, and cited as evidence a photograph from the webcam embedded in [his] personal laptop issued by the school district."

The suit contends the Lower Merion School District, one of the most prosperous and highest-achieving in the state, had the ability to turn on students' webcams and illegally invade their privacy.

The suit says that in November, assistant principal Lynn Matsko called in sophomore Blake Robbins and told him that he had "engaged in improper behavior in his home," and cited as evidence a photograph from the webcam in his school-issued laptop.

Matsko later told Robbins' father, Michael, that the district "could remotely activate the webcam contained in a student's personal laptop . . . at any time it chose and to view and capture whatever images were in front of the webcam" without the knowledge or approval of the laptop's users, the suit says.

A security professional in New York has investigated the technical claims and found them convincing. He also expanded on the original news story with some circumstantial evidence:

The truly amazing part of this story is what's coming out from comments from the students themselves. Some of the interesting points:

  • Possession of a monitored Macbook was required for classes
  • Possession of an unmonitored personal computer was forbidden and would be confiscated
  • Disabling the camera was impossible
  • Jailbreaking a school laptop in order to secure it or monitor it against intrusion was an offense which merited expulsion

When I spoke at MIT about the wealth of electronic evidence I came across regarding Chinese gymnasts, I used the phrase "compulsory transparency". I never thought I would be using the phrase to describe America, especially so soon, but that appears to be exactly the case.

I can't wait to see how this turns out.

Paper or plastic?

Via Going Green @ Your Library, an elucidation of everything you need to know about grocery bags. But:

Ultimately, neither paper nor plastic bags are the best choice; we think choosing reusable canvas bags instead is the way to go. From an energy standpoint, according to this Australian study, canvas bags are 14 times better than plastic bags and 39 times better than paper bags, assuming that canvas bags get a good workout and are used 500 times during their life cycle. Happy shopping!

Ouch

Top Palin aide Meghan Stapleton quit today, with this statement:

"While I had hoped to work together on so many more projects, time with my precious 2-year-old has been further minimized with the whirlwind commitments of all things Palin,” she told the SarahPAC staff. “I have done my best to scale back, but [my two-year-old daughter] Isabella is now resorting to hiding my BlackBerry, and she shouldn't grow up begging for a mother to start acting like a mother.”

With friends like these...who needs to carry her kid around like a prop?

Commuting home to work

I'm splitting my time between Chicago and Raleigh lately, and it looks like I'll continue to do so for quite a while. This causes one minor inconvenience: my car doesn't fit in the overhead compartment on a CRJ. (For that matter, an anorexic gerbil won't fit in the overhead compartment on one of those things, but that's another issue.)

Chicago, however, is a major city with an extensive public transportation system (no snickering from natives, please). Chicago also has Zipcars, a by-the-hour car-rental cooperative, with six cars stationed less than four blocks from my house. Four blocks—800 m—seems to suburbanites like a very long walk to get a car, but actually, I'm lucky if I get to park my own car that close most days. So this is an improvement.

iGo, which costs a little less and works in partnership with the CTA, is another option. Unfortunately they don't have any cars within 1500 m of my house. Walking around the block to get the Zipcar suddenly seems more attractive. Walking eight blocks to get a car is less so.

Zipcars also has the advantage of national reach. Given how often I travel (especially to San Francisco), this has tremendous appeal.

Now if only Chicago had a puppy-rental service for those times when I miss Parker...

World's strangest airports

These are kind of cool:

Winston Churchill Avenue, Gibraltar's busiest road, cuts directly across the runway. Railroad-style crossing gates hold cars back every time a plane lands or departs. "There's essentially a mountain on one side of the island and a town on the other," Schreckengast says. "The runway goes from side to side on the island because it's the only flat space there, so it's the best they can do. It's a fairly safe operation as far as keeping people away," he says, "It just happens to be the best place to land, so sometimes it's a road and sometimes it's a runway."

Number 8, St. Maarten's Princess Juliana, is one of my favorites.

Gut feelings

You really have them:

Technically known as the enteric nervous system, the second brain consists of sheaths of neurons embedded in the walls of the long tube of our gut, or alimentary canal, which measures about nine meters end to end from the esophagus to the anus. The second brain contains some 100 million neurons, more than in either the spinal cord or the peripheral nervous system, [says Michael Gershon, chairman of the Department of Anatomy and Cell Biology at New York–Presbyterian Hospital/Columbia University Medical Center].

... "The system is way too complicated to have evolved only to make sure things move out of your colon," says Emeran Mayer, professor of physiology, psychiatry and biobehavioral sciences at the David Geffen School of Medicine at the University of California, Los Angeles (U.C.L.A.). For example, scientists were shocked to learn that about 90 percent of the fibers in the primary visceral nerve, the vagus, carry information from the gut to the brain and not the other way around. "Some of that info is decidedly unpleasant," Gershon says.

There are some intriguing corollaries to this:

Scientists are learning that the serotonin made by the enteric nervous system might also play a role in more surprising diseases: In a new Nature Medicine study published online February 7, a drug that inhibited the release of serotonin from the gut counteracted the bone-deteriorating disease osteoporosis in postmenopausal rodents. (Scientific American is part of Nature Publishing Group.) "It was totally unexpected that the gut would regulate bone mass to the extent that one could use this regulation to cure—at least in rodents—osteoporosis," says Gerard Karsenty, lead author of the study and chair of the Department of Genetics and Development at Columbia University Medical Center.

... Serotonin seeping from the second brain might even play some part in autism, the developmental disorder often first noticed in early childhood. Gershon has discovered that the same genes involved in synapse formation between neurons in the brain are involved in the alimentary synapse formation. "If these genes are affected in autism," he says, "it could explain why so many kids with autism have GI motor abnormalities" in addition to elevated levels of gut-produced serotonin in their blood.

Scientific American also investigates whether untreated vision problems lead to age-related dementia. Very interesting.
