I hate PowerPoint, so I really wanted to link this essay. Unforunately, it's half a rant about how kids these days are stupid and should get off my lawn and half a description of how deep, inspiring humanities are better than soulless sciences.

You're better off reading this old but still relevant article, titled "PowerPoint is Evil":

Presentations largely stand or fall on the quality, relevance, and integrity of the content. If your numbers are boring, then you've got the wrong numbers. If your words or images are not on point, making them dance in color won't make them relevant. Audience boredom is usually a content failure, not a decoration failure.

Jeffrey Greenberg loads his carry-on bag with some liquids, boxcutters, a Hezbollah flag, and terrorist propaganda. Then he meets a collaborator who provides him with a forged boarding pass at the airport Starbucks:

He had taken the liberty of upgrading us to first class, and had even granted me “Platinum/Elite Plus” status, which was gracious of him. This status would allow us to skip the ranks of hoi-polloi flyers and join the expedited line, which is my preference, because those knotty, teeming security lines are the most dangerous places in airports: terrorists could paralyze U.S. aviation merely by detonating a bomb at any security checkpoint, all of which are, of course, entirely unsecured.

The collaborator, predictably, is Bruce Schneier. Even more predictably, he gets through security with no problem, despite declining to show ID.

It's local, it's about beer, it's about religion. What's not to like in this article?

Clay Risen, in an interesting article about the most important person in American education:

Behind the fighting lie basic questions: What makes a good teacher? And how do you recognize one? For Rhee and her fellow reformers, the answer is data. Lots of data. There may be many unquantifiables in teacher quality, but most of the traits that matter to reformers can be put into numbers.

I think she's right, but even if Michelle Rhee is on the wrong track, we still need lots of people like her. One of them will stumble on something that works.

Alan Jacobs writes about Mountains Beyond Mountains (which is a great book), and the idea of the "long defeat".

The expectation of victory can be a terrible thing — it can raise hopes in (relatively) good times only to shatter them when the inevitable downturn comes. Conversely, the one who fights the long defeat can be all the more thankful for victories, even small ones.

Voter registration drives are a fraud:

Having students learn more is a legitimate interest of schools, and if students learn more they should get better grades. But it is a fraud for schools to raise student grades when they have not actually learned more. Similarly, it might be good things if citizens were better informed and considered their political process legitimate, and these good things might show themselves via more votes. But just pushing more people to vote, without their actually becoming more informed or considering the process more legitimate, is also a fraud.

I react pretty strongly to this kind of thinking, where the underlying reasoning seems to be "everybody but me and my friends is stupid."

The future of NASCAR:

As the fans join in a full-throated cheer, 43 of the world's best drivers reach down and press a button. What follows is unprecedented: pin-dropping silence, save for 43 small clicks.

With any luck, the electricity will come from clean, safe, efficient nuclear power.

Survive the meltdown by living in a smaller house:

Homes 1200 square feet or smaller lost just one percent of their value over the previous year, compared to 3.1 percent losses for midsized houses and 2.8 percent losses for large homes.

A clever thief hires accomplices on Craigslist. The beautiful thing is, he doesn't even need to pay them. The really beautiful thing is, his getaway vehicle was an inner tube.

Sometimes I crack open the Wall Street Journal and am amused to find that some copy editor has decided to insert the word "mackerel" at random points in the story:

There's been a mackerel economy in federal prisons since about 2004, former inmates and some prison consultants say...

Current inmates can't discuss mackerel transactions without risking discipline, say several lawyers and consultants who represent incarcerated clients...

Ethan Roberts knows about mackerel discipline first hand...

At Lompoc, says spokeswoman Katie Shinn, guards "are not aware of such a problem with mackerel."

Then I find out it's not a mistake. This is actually an interesting article.

DARPA has a list of twenty-three mathematical challenges that they want solve. Some of them are interesting, some of them are vague:

Mathematical Challenge Six: Computational Duality
Duality in mathematics has been a profound tool for theoretical understanding. Can it be extended to develop principled computational techniques where duality and geometry are the basis for novel algorithms?

Overall, reading the document I'm not entirely convinced that the people putting it together know what they're talking about. Not that I would do much better with many of the topics, but still.

I think I'm going to tackle Challenge Ten, just so I can tell people I'm working on "algorithmic origami."

Environmentally aware people don't make real sacrifices:

The longest and the most frequent flights were taken by those who were most aware of environmental issues, including the threat posed by climate change.

I'm certainly a hypocrite in this regard; I fly more than average, and therefore pollute more than average, regardless of whatever other environmentally friendly measures I take.

Bruce Schneier thinks you should be arrested for trying to bring toothpaste on a plane:

If some copycat terrorists try to bring their liquid bomb through airport security and the screeners catch them -- like they caught me with my bottle of pasta sauce -- the terrorists can simply try again. They can try again and again. They can keep trying until they succeed. Because there are no consequences to trying and failing, the screeners have to be 100 percent effective. Even if they slip up one in a hundred times, the plot can succeed.

Too many people go to college:

We should look at the kind of work that goes into acquiring a liberal education at the college level in the same way that we look at the grueling apprenticeship that goes into becoming a master chef: something that understandably attracts only a few people. Most students at today’s colleges choose not to take the courses that go into a liberal education because the capabilities they want to develop lie elsewhere. These students are not lazy, any more than students who don’t want to spend hours learning how to chop carrots into a perfect eighth-inch dice are lazy. A liberal education just doesn’t make sense for them.

Paul Tough likes Obama's education plan. Megan McArdle doesn't. The funny thing is, they both offer their own idea of what we should do about education, and they both say the same thing. Here's Tough:

Help persuade teachers to give up some job security in exchange for more pay. Help the school systems get rid of poor-performing teachers—not just a few of them, but a big swath, the whole bottom tier.

And here's McArdle:

Scarsdale knows that if it doesn't keep the schools successful, middle class parents will leave, taking their lavish tax dollars with them. Riverdale, too, knows that it needs to keep parents happy and test scores high. The New York City public school system, on the other hand, mostly has to get butts in seats, because that's how they get their money. It's not that the teachers don't want to teach kids; it's that they don't have to.

I agree with both of them.

Walmart is making you thinner:

We estimate the impacts of Wal-Mart and warehouse club retailers on height-adjusted body weight and overweight and obesity status, finding robust evidence that non-grocery selling Wal-Marts reduce weight while grocery-selling Wal-Marts and warehouse clubs either reduce weight or have no effect. The effects appear strongest for women, minorities, urban residents, and the poor.

Upset that kids in his inner-city district go to underfunded schools, James Meeks buses a thousand black students to the suburbs:

He bused them all to Northfield, a wealthy, mostly white Chicago suburb, to the lavish campus of New Trier Township High School, a public school with four orchestras, a rowing club, a course in "kinetic wellness," and AP classes in French, Spanish, German, Japanese, Latin, and Chinese. You know, your basic American public school. The Chicago kids lined up and tried to enroll for classes.
