The biggest factor influencing long term stock returns in real growth in earnings. Companies don't pay out all profits to shareholders as dividends. They can also reinvest in their own business (e.g. build a new factory) or buy back s

Yes, stock market growth is largely driven by the real growth in earnings and dividends. Nominal figures are not adjusted for inflation. "Real" numbers are adjusted for inflation (in economics-speak). The stock market (e.g. S&amp

Yea, agreed, Spark definitely isn't a database, it's a query engine. I agree that the traditional Spark notebook query interface was a lot easier for people with pandas (or DataFrame experience) to understand. But their new SQL q

The new data tools I've seen are complex under the hood, but offer elegant user experiences, giving the best of both worlds. You referenced a 500 line Python script being refactored with Rust and make me think of the Polars project: h

HDF5 has some limitations that make it suboptimal for cloud based storage systems. Zarr overcomes these limitations for array data and Parquet overcomes these limitations for tabular data.

Parquet is a wonderful file format and is a dream to work with compared to CSV. Parquet embeds the schema in the footer metadata, so the query engines don't need to guess what the column names / data types are. Parquet used to be

I like Black for normal Python code, but it seems to mangle Pandas / Dask code at times. I still use it extensively cause it doesn't seem like there are other good alternatives. I wrote a blog post on how to use Black in Jupyter

Kinesis Advantage 2 is great, but it's massive and hard to travel with. Looks like the 360 might be a bit easier to travel with. The Kinesis Advantage 2 fits a Magic Trackpad perfectly right in the middle of the keyboard. This lets y

The Fed was initially saying the inflation was transitory, but have recently dropped the "transitory" label. Back in July, Siegel pointed out that the M2 money supply is 30% over pre-pandemic levels and predicted that would transl

Yea, there was a JSON parser in the Scala standard lib at one point and it was then deprecated & removed. Guess it's easy to make a "hello world" JSON lib, but maybe not the best addition to the standard lib, haha.

> Scala offers you many design choices that work well in skilled hands I agree that Scala works well in some skilled hands (see Li's libs), but the people that write the most terrible Scala programs actually know a lot about Scala.

Navigating well designed, huge monorepo Scala codebases is surprisingly easy. Spark is a great example of a huge monolith that's relatively easy to work with considering the complexity of the app. If you follow the design principles o

I agree that different factors cause some land to be more valuable than others. I'd argue that the factors you've listed are relatively easy to factor into an appraisal. Property taxes, in comparison, are really hard to compute.

This is a great question. Land taxes are great because there is less of a deadweight loss. Governments need money to operate. All else equal, we should get governments the money they need without wasting people's time to comply with

All the land value taxes would be public record. Think it'd be hard to have your land valued differently than your neighbor.
