The Apple iTunes Music Store is now the #2 music retailer in the world, behind WalMart. This figure is for all music including CD's, not just digital music. According to the article:
It was only eight months ago that iTunes passed Amazon to become the number three music retailer. Wal-Mart is still holding its own with a massive brick-and-mortar retail business in addition to its online music store, but must be getting nervous as iTunes continues to close in.

Strategic Conquest on the Mac: I used to be a big fan of the Delta Tao game "Strategic Conquest" back when I owned a Mac SE in the 1990's. I stopped playing when I had to switch to a Windows system for work reasons, but now that I have a MacBook Pro, I wanted to find a way to play it again. Unfortunately, it doesn't run on Intel Macs. But after doing a little searching I found this page, "How to run Classic (pre OS X) apps on Intel Macs" which discusses how to use the Basilisk and SheepShaver emulators of classic Mac, as well as the following very useful comment from Mac user John Rethorst:
I've built a complete SheepShaver install, including _everything_ needed to run, as well as the last version of WordPerfect and several utilities. To download this 243mb image, go to http://groups.yahoo.com/group/wordperfectmac, to the Links section, to the "SheepShaver and Basilisk" folder, and click "SheepShaver-WordPerfect Install". It's about 20 minutes on a fast connection.
I downloaded his install as well as a copy of "Strategic Conquest" from Delta Tao (purchased for $24.95), and it works like a charm! The SheepShaver software nicely emulates a Macintosh PPC running OS 7.5 with 256 colors.

Now I just have to figure out if I have enough air cover to plan a successful amphibious invasion of the enemy continent...

Update on the American Dream: In response to my earlier post, "Testing the American Dream", a lengthy comment thread has erupted here on QandO.net, some supporting the overall conclusion and others attacking it for a variety of reasons.

Of the supportive comments, this one by "Minh-Duc" struck me the most:
Why bother with the experiment. Just go talk to immigrants. I arrived to the U.S. with a shirt on my back and spoke no English. I consider myself in the upper middle class now. This is the story that repeated itself a million time in the history of this great nation.

Speaking of family obligations; both of my parents were janitors, my uncle and aunts were (and still are) janitors. My uncle and aunt is even more successful. They put three kids through medical school.

"The Hunting Strategies of Carnivorous Plants".
Another proposed solution to the airplane boarding problem:
[Physicist Jason] Steffen found that the worst method for boarding a plane is boarding from the front to the back, since passengers have to wait and step over each other to get to their seats. ...Quite unexpectedly, then, Steffen found that the common back-to-front boarding method is actually the second worst method possible, only slightly better than boarding front to back.

...Using a combination of a Monte Carlo optimization algorithm and intuition, Steffen determined an optimal boarding method, which could make boarding go 4 to 10 times faster than the worst method, depending on the size of the plane. In the optimal method, passengers would board 10 at a time in every other row (since loading luggage requires about two aisles of space). This way, passengers could always be boarding luggage or sitting in their seats, rather than waiting in the aisle, as in the two previous methods.

However, Steffen also acknowledged that the optimal method might not be practical, since passengers who sit next to each other often travel together, and prefer to board together. He proposed a modified version, where passengers board in blocks of three consecutive seats on one side of the plane in every other row. In this strategy, there would be four boarding groups, with passengers in the same row on the same side boarding together. This method provided a decent middle ground, as it was twice as slow as the optimal method, but twice as fast as the conventional method. Although getting passengers to line up in their correct groups might sound challenging, Steffen noted that Southwest Airlines has been experimenting with having its passengers line up in numerical order -- so the logistics wouldn't be inconceivable.

Steffen also identified several other boarding strategies with results superior to the conventional method. Contrary to our tendency for order, even completely random boarding proved to be a good alternative. In fact, random boarding was nearly as fast as the modified optimal method. Plus, by its very nature, it has the advantage of not requiring airline attendants to organize boarding passengers in any way. And the random result also shows that, when passengers board out of order in the other strategies, the results will still be better than the conventional boarding method.

The main advantage of the alternative boarding methods is that they allow several passengers to load their overhead luggage simultaneously, which Steffen identified as the largest factor in determining boarding time.
The merits of random boarding have been discussed here in this 2006 article.
The Onion asks the tough question, "Do We Really Want Another Black President After The Events Of Deep Impact?":
Have we learned nothing from the tragic events of 1998, when, under the watch of President Morgan Freeman, this nation was plunged into chaos, and hundreds of millions of people died at the hands of the deadly Wolf-Beiderman space rock?

..As if that is not enough, history shows us that, besides carrying the baggage of a guaranteed asteroid strike, black heads of state also give terrorists extra motivation to destroy the United States. During the presidency of 24's David Palmer, there were no fewer than four nuclear bombs smuggled into this country. That's four more than under any white president.

...Need I even mention that former President Chris Rock and his administration's slogan was "The only thing white is the house"? Though this attitude broke down the stuffiness typically associated with proper White House decorum, President Rock's laissez-faire approach not only made a mockery of the office at home, but made the United States look like a joke abroad.

Testing the American Dream: Having been told that it was extremely difficult for poor people to advance up the economic ladder in America, college graduate Adam Shepard conducted an interesting experiment.

He decided to start from the very bottom of the economic ladder, with "a gym bag, $25, and little else". He moved into a homeless shelter "on the wrong side of the tracks in Charleston, S.C." He set as his goal "to have a furnished apartment, a car, and $2,500 in savings within a year" without relying on his education or his former contacts.

He worked his way out of poverty, found work as a day laborer, made new friends, and landed a steady job at a moving company. He had to quit his experiment after 10 months because of learning of an illness in his family, "[b]ut by then he had moved into an apartment, bought a pickup truck, and had saved close to $5,000."

According to the article:
The effort, he says, was inspired after reading "Nickel and Dimed," in which author Barbara Ehrenreich takes on a series of low-paying jobs. Unlike Ms. Ehrenreich, who chronicled the difficulty of advancing beyond the ranks of the working poor, Shepard found he was able to successfully climb out of his self-imposed poverty.
Clearly, this shows the crucial role that a person's character, attitude, and work ethic play in whether he is successful or not, as opposed to the exact magnitude of material resources he starts with.

The full article tells more Adam Shepard's fascinating story: "Homeless: Can You Build a Life from $25?"

He has also written a book about his experience, entitled, Scratch Beginnings: Me, $25, and the Search for the American Dream. It looks like his book has gotten consistently high reviews on Amazon.

Update: In response to this post, a lengthy comment thread has erupted here on QandO.net, some supporting the overall conclusion and others attacking it for a variety of reasons.

Women and marriage: Many people have blogged about this article on whether women should "settle" when they choose which man to marry. One question which isn't quite answered in the article is whether "settling" means compromising on core values that are genuinely important to oneself, or whether it means giving up on old priorities that one now realizes aren't really important (but may have seemed important earlier in life).

"With Mini in vivo Robots, Anyone Can do Surgery":
The researchers tested the mini robots on three NASA astronauts and one surgeon who were undergoing long-term training in an underwater habitat called the NASA Extreme Environment Mission Operations (NEEMO), located 20 meters underwater off the coast of Key Largo, Florida. The four "Aquanauts" received brief training on how to perform two surgeries – bowel inspection and stretch-and-dissect – and were also evaluated on how well they could perform another surgery – an appendectomy – for which they received no training.

...Another notable result was that the crew members were able to successfully perform the appendectomy, even though they had not been trained on that procedure. This success demonstrates that telementoring can be used to enable individuals trained on basic skills to build upon their skills to complete more complex procedures.

"Better Than Free": Interesting article on economics in the internet era, when information dissemination is free or nearly so.
When copies are free, you need to sell things which can not be copied.

...From my study of the network economy I see roughly eight categories of intangible value that we buy when we pay for something that could be free.

In a real sense, these are eight things that are better than free. Eight uncopyable values. I call them "generatives." A generative value is a quality or attribute that must be generated, grown, cultivated, nurtured. A generative thing can not be copied, cloned, faked, replicated, counterfeited, or reproduced. It is generated uniquely, in place, over time. In the digital arena, generative qualities add value to free copies, and therefore are something that can be sold.
