Warren Buffett: If you could invest in one classmate ...

I found this Warren Buffett quote in this Inc. Magazine article back in 2018:

“If you could invest in only one of your fellow classmates, who would you choose? If you could buy, say, 10% of the future earnings of just one classmate, who would you choose? What would you look for?”

The idea is that you won’t just necessarily look at raw IQ, you’ll look at other personality attributes, such as drive, ambition, and hopefully other attributes like honesty and integrity.

Scala version of Collective Intelligence Euclidean distance algorithm

While reading the excellent book, Programming Collective Intelligence recently, I decided to code up the first algorithm in the book using Scala instead of Python (which the book uses). This is a Euclidean distance algorithm, and it provides one way to compare two sets of data to each other, and attempts to score the similarity between the data sets.

Without any further introduction (and assuming you have the Collective Intelligence book), here's the Scala source code for the Euclidean distance algorithm as described in the book:

IQ is not EQ

One of the things you have to remember when working with human beings is that IQ is not the same as EQ, and they’re rarely equal. Some people have a horrible temper. One guy I know is smart, but he remains the biggest jerk I’ve ever met.

I remember hearing one time that when people are hurt in their childhood or teen years they stop developing emotionally at that point. So if they are somehow hurt when they are twelve years old, they can be thirty years old physically but only twelve emotionally. I don’t know if that’s 100% true, but it seems like it in some cases I know. (And the hard thing is that these people don’t know that they have these problems.)
