Correlation does not imply causation - sports department

Why Do Former High-School Athletes Make More Money? - The Atlantic:

I don't have a kid in high school, but I know extracurricular requires commitment from parents, at least for elementary school years, which I know first hand. By accident, committed parents matters in education ...

We parents joke about that too, no matter it is baseball, basketball, swimming or scouts, we almost always meet the same bunch of parents, from one activities to another. So my hunch is that the extracurriculars at elementary school years is good indicator of commitment of the parents. At the same time, early start in sports would lead to higher participation in later years.

To measure how much kids "acquired" from sports, we need to control for other factors.

R vs. Python, round #???

An R Enthusiast Goes Pythonic! | Data Until I Die!:

I found myself stumbling a lot trying to figure out which Python packages to use for each particular purpose and I tended to get easily frustrated. I had to keep reminding myself that it’s a learning curve to a similar extent as it was for me while I was learning R. This frustration should not be a deterrent from picking it up and learning how to do machine learning in Python.

Game of Thrones - What's the worst thing that could happen?

The quote from Vox is right on:

"This, honestly, is a problem endemic to the show, and one that may eventually tear it down. On Game of Thrones, suffering isn't something characters go through; it's something the writers visit on the characters. It often seems as if the show starts from the premise of, What's the worst thing that could happen to this person? and then presses that button over and over again."
The show has not gone deep into the character as it could have. It makes me feel that the writers care more about the response from the viewers than the characters or the story. It is a tool the awe the viewers. It is a way to make money, not exactly a piece of art.
