I feel like I can hear improvement over the last three months or so of regular practice. My lines sound more musical and less mechanical to me. Of course, I hear a million mistakes too.

I'm working on it! :P

This is a perfect example of a pretty important paper I read on problem solving skills. It details the difference between well-defined and ill-defined problems, the one you set out to "solve" being the latter.

What makes yours an ill-defined problem is that there's no single, definitive "right" answer, no single or defined set of obvious solution paths, nor are the constraints really defined at all. Problems we encounter in our every day life are typically ill-defined. As opposed to well-defined problems, which are your typical back-of-the-textbook problems which can, essentially, be stripped down to a linear algebra problem regardless of what words are wrapped around it. There's typically a single right answer that you can verify, one solution path... sometimes more, but all fairly rigidly defined.

The thinking has been that learning to solve well-defined problems leads to sills in solving ill-defined problems. As it turns out, that's not the case. There are a lot of secondary skills in solving ill-defined problems that are actually rather difficult to acquire. The thing where you assumed the wings were rectangles, or that you looked up some values for wing flapping rates. Identifying and making assumptions, and recognizing the consequences thereof, is critical to solving these kinds of problems. We do it all the time, and it's something I'm going to work in instilling in my kids this year. This is just the tip of the iceberg, but I'm sure you get the gist.

Whenever I read about using Arduino to interface with a RC receiver, people talk about using pulsein(). If I had analog inputs to spare, couldn't I just use analogread()? It's just a PWM signal, right?

I also played with an RC calculator, and the problem is that an RC filter, at best, only averages the PWM signal. The PWM signal has a duty cycle of only about 5-10%, so the output of the RC filter will only be about 0.25-0.5 volts, regardless. It seems like the pulsein() approach really is the best one, or if one wanted to build an analog circuit, one would need op-amps.

This is what I think of Netflix right now.

Ouch. What a nail-biter of a hand. And insult to injury on the river.

+Eric Wilson The hand started with Ferguson all-in, and a 3:1 dog to Hellmuth. After the flop, Hellmuth had a set of tens, and Ferguson's odds of winning were only 5%. He needed either two aces to come, giving him a higher set, or he needed two clubs to come and make a flush. When the four of clubs came, his odds improved to 18%. One more club would make a flush, but it could not be the ten of clubs, because that card would give Hellmuth four of a kind. And that's exactly the card that came out. So Ferguson made his flush, but still lost to the only card that would give Hellmuth the win over that flush. And since he was all-in, he was eliminated from the tournament as a result.

I will probably not do this, but I think it would be hilarious to have a multirotor with blinky lights or whatever, and fly it around at night at Alchemy, playing "Never Gonna Give You Up" through a sound system.

They say, "If you don't want to crash it, don't fly it," but losing a model this size must still be heartbreaking.

EDIT: This was most likely a mechanical failure related to the left side engine(s) not working properly.

I think in that one, he mentions the 4 motors working to fly..

Posts from /r/WTF really need to be flagged on Reddit's front page. Many a time, I blithely click through to some horrible photo, only to shout, "WHAT THE FUCK?!?!" and then realize the post was to /r/WTF, so I should have known better.
