Maybe you've ever seen the cool proof that "Tetris is NP-complete". I loved the paper and it was very entertaining. But it involved a much broader and general Tetris problem than the one found in Nintendo Gameboys, because the width and t

You are correct, but the author's big leap of faith is that our particular one case of the problem is intractable. I'm claiming the reduction from 3-SAT to his market problem is likely broken because the general market problem is subject t

Very interesting, if you are familiar with the "Gold Pass" vs "Silver Pass" movie gift cards, there is a tiny subset of your idea built in there. The idea is Silver passes are cheaper than Gold passes, but you can only watch movies that a

"Terrorism" became an overloaded term once we coined the term "War on Terror". While this is an act of terrorism for sure, this is not the Terrorism that originates from those we are supposedly fighting in the War on Terror, therefore we sh

I love the "Boys and Girls" question, because most people get it wrong first pass, most computer science folks would get it after a few minutes of work, and a Bayesian would immediately nail it. Plus, it's seems so simple we could pose it t

The only "answer" that is hard to match to a standard brainteaser question was "they are seven and a half degrees apart." I believe the question is, "what's the angle formed by the hour-hand and the minute-hand of a clock when it is 3:15?"

I guess the lesson is, anything truly game-changing needs to first seem stupid to most people? Sadly, that's not so actionable since you get the same reaction when your idea is actually stupid.

I'm fine with legit collections calls as long as a human collector has to waste equal or more time trying to reach me. This recent invention of automated collections calls seems to shift an enormous amount of abusive power to the collector.

This reminded me of the Don Dodge GOOG/MSFT transition post. Maybe it was the displays of platform loyalties, or their perceived backwardness of the technology habits? http://dondodge.typepad.com/the_next_big_thing/2009/11/thank...

It sounds like you want to invest the money in yourself, which is understandable and entrepreneurial. As life continues, you'll find yourself with increasingly more disposable money (hopefully), and directly investing in yourself doesn't sc
