For the winners / losers computation, one thing that's clear is that land value taxes are highly progressive. Rich people own most of the land. There are no tax loopholes to evade land taxes.

Nah, it's really easy to calculate the value of the land. Once you calculate the value of the land, then it's pretty much applicable to the whole neighborhood too. It's a one-and-done analysis. This isn't my opinion.

I'm not a huge fan of how deadweight loss is defined in the article: > virtually all economists agree that land value tax has zero "deadweight loss"–a fancy word for a drag on the economy that makes certain activities no l

It's difficult reading articles without any Headings! Data mining is common in finance. Finance PhDs are constantly identifying new "factors" (e.g. value, momentum, price/book) based on historical data that don't p

Scala is a good example of a weird programming language with smart users. The book Hands on Scala Programming is a great way to learn how to express code and think in new ways. Paul Graham also talks about the power of different programmin

I agree that most of the ML ecosystem libs are in Python, but don't think they're easily accessible via PySpark. PySpark is a thin wrapper on Scala Spark (via py4j). PySpark has better interop with Scala/Java libs. Here&#x
