Did you manage to heal the IT band tendinitis and if so, what did you do?

Author here. I often find when working on rich editors that I want to see a graphical representation of the editor dom with the current selection and any hidden or hard-to-see characters. That's what ViewDom does. Unfortunately it still needs some work on mobile devices but I already find it useful.

Ok, I re-enabled the back button.

it should work on desktop, does anything render or do you get a blank screen?

sorry about that, I disabled it since I was accidentally hitting it on my phone but I agree it is annoying.

I often tell people that I love my dog more than any human has ever loved a child, but I don't love this study.

The result is fairly obvious to any dog owner, but the study is representative of the type of "pop" science that appears so often in the news but carries little actual significance. 34 dogs total, 17 in each group (humming vs crying), 9 of which respond to humming and 7 of which respond to crying, albeit the latter much faster than the former. Of those 34 dogs, 16 were therapy dogs. While the time difference is large, more dogs respond to humming than crying.

So we have a very small sample size which is biased towards therapy dogs. It is also very susceptible to p-hacking. Why "Twinkle Twinkle Little Star"? Was this the song that produced the largest effect out of 20 different songs? Why do more dogs respond to the humming than crying but the dogs that do respond to crying act so quickly? Were the crying sounds much louder than the humming? Why not crying vs yelling, both of which are likely of similar volume? And so on.

As an American living in Europe I would call pastries for breakfast a western breakfast. The idea that the US eats nothing but sugar for breakfast and this is unique in the world is way off base. Among my friends and colleagues, mostly Europeans from many different corners of Europe, it is exceedingly common to eat some form of croissants or pastries for breakfast. I think the difference lies in the portion sizes and density of these pastries.

I'll have pastries once a week when I have breakfast with my wife, but otherwise I tend towards yogurt, bananas, and a handful of cereal. I'm not on the "sugar is evil" bandwagon. I definitely do manage my weight but it is more about calorie control than sugar intake. A serving of yogurt will have between 100 and 220 calories depending on if it is plain or has a bunch of good stuff added (I like both), a banana around 100 calories, and a handful of cereal about the same. I love sugary cereal and don't want to eliminate it from my diet. The difference between how I consume it now and when I was a kid is that I really eat one handful at breakfast time whereas in my childhood would eat one to two large bowls.

Granola is the killer. The crunchy kind of granola has more calories per gram than sugary cereal and unfortunately is more dense. I see many people trying to eat a healthy, low calorie yogurt and granola breakfast only to fill the bowl with granola. Game over.

"Having performed thousands of similar hair examinations over the previous 10 years, the FBI agent told the court, there had been only eight or 10 times when hairs from two different people were so similar that he could not tell them apart"

At worst this is a 1% error rate, at best 0.1%. Scientific validity aside, I find it unbelievable this was not considered reasonable doubt.

What caught my eye was the oscillation in the abundancy graph, there is a tendency for even atomic number elements to be more abundant than odd atomic number elements. Looking at the original Wikipedia article leads to the Oddo-Harkins rule http://en.wikipedia.org/wiki/Oddo%E2%80%93Harkins_rule. There is more discussion on the stability of even vs odd atomic number elements here: http://en.wikipedia.org/wiki/Even_and_odd_atomic_nuclei. From the latter link, roughly 60% of stable nuclei have an even number of protons and an even number of neutrons. Only 2% have an odd number of protons and an odd number of neutrons.

It would be nice if someone could explain any of the exceptions to the Oddo-Harkins rule, such as the dip at atomic number 44, Ruthenium.

Hi, author here, my statistics abilities are far from perfect so I'd welcome any feedback. I have a feeling there is a much easier way to get to the full answer than the statistical hoops I jumped through.
