I've had fun doing the haskell challenges. I really like the peer review aspect of it and the git style terminal submissions. But these are just small practice problems and are not geared towards "Teaching you to code well enough to get a job". It's just one of many helpful ways to learn the ins and outs of a particular language.
It seems to me encouragement is the dominant response, both here and in the original post.
My criticism would be that in her post she highlights only the negative comments she got. When, on the whole, the community votes her posts up and the top comments are always positive.
1. Attenuating non relevant differences absolutely makes sense. Attenuating is used in the context of controls to eliminate confounding variables.
2. I'm unsure how this scientific research shows bias. Small sample size, perhaps, but not much in the way of bias. You on the other hand are taking a scientific study as a personal assault on your lifestyle. The article doesn't even claim that the changes in white matter have adverse health effects.
here is an excerpt: It's also not clear whether the structural changes have any implications for people's health.
You've missed the point. This is not about those that live healthy lives as nightowls, but those that do not. Can we attenuate the differences among the owls to figure out why some are unhealthy and others are not. Furthermore, can we figure out the attributes that larks have, that on the whole seem to make them healthier than owls. Then, maybe we can adjust the lifestyles of the unhealthy larks to have them lead a healthier life.
The DOE also studied what Robert Jackson 'plans' to do. That is using injections to trace leaks. This is not proof of leaks, it is proof that houses near methane deposits have more methane in their drinking water.

Obviously, this study needs to be repeated many more times and more regulations need to be put on fracking, but the technology is getting better already.
The Daikin in my building runs at 100% capacity down to -4F. The last time NYC recorded below -4 was 1943.
