Ditto. Great talk.

Stanford is the most affordable school in the country. Pretty much bar none. If your family earns under $100k / year, you go for free. Many families with incomes in excess of $200k still get some form of financial aid.

They do have a business going, to be sure, but it's not built on gorging people on tuition. Many (most?) don't pay that number. And even it is extremely reasonable if you think about what the market clearing price would be.

Anyone interested in the early days of personal computers should check out Triumph of the Nerds. It's many of the same people but interviewed 16 years ago. Awesome stuff.

Both can still be true.

The majority of people do not die as children, but the effect of those who do is disproportionately large on "life expectancy" because it's an average.

Let's say that 23% of children die in their first year (true in Sweden in 1751). Let's say everyone else dies at 80. Life expectancy is 61.6 years.

Now let's say time passes and now 0.2% of children die in their first year (true in Sweden today) and everyone else dies at 80. Life expectancy is now 79.7 years. It jumped over 18 years (30%) with no one living any longer than before. Additionally, the percentage of children dying was never even 1/4 of the total, so the vast majority of people still died from other causes.

The point is that the linked chart represents numeric percentages of people dying, while life expectancy weights younger years much more heavily.

Most of the progress that has been made in life expectancy is from young children, but most of the progress in "what actually kills people" has been for older people.

This works, but setting the cornerRadius property kills performance. It's preferable to overlay an image with black corners or to bake the black corners into your art assets.

Doesn't this mean that others made a killing, taking advantage of all the mispriced orders?

I can't speak for the creators of R, but I have a strong suspicion that it wasn't intended for erehweb or MBAs. It's not Microsoft Excel, its R. It's used by PhD researchers in Mathematics, Statistics, Economics and Political Science.
