I actually believe this is a distinction without a difference. If you look at Klein’s RPD model, the implicit memory operation is pattern matching against a prototype . The situation doesn’t have to be exactly the same as an old one, becau

In this instance, the metagame is the optimal strategy given your gaming group’s current strategic preferences. I’ve found that over time, the dominant tactics in Splendor for my group swing between build and buy. People do whatever is nece

I absolutely agree. However, in my experience, recognition of the metagame comes way before you actually require it.

As much as I personally like and respect Shane from Farnam Street, I don't like the current trend of mental model writing as much. I'm probably one of the more vocal critics, in fact (see: https://commoncog.com/blo

Thank you for saying this! I think your definition of OLAP is good, but the definition of OLAP cube could simply be 'a data structure that is basically a very sophisticated nested array'. I'm oversimplifying, of course — ther

Amazon also uses Redshift, which is a modern columnar database. An example does not an argument make.

I went back to read most of the academic literature on OLAP cubes while working on this piece (which, unlike vendor marketing, is used with consistency since the early 80s). OLAP cubes or data cubes refer specifically to a data structure. A

There are huge problems with that piece. For starters, OLAP != OLAP cube. Columnar databases and OLAP cubes are both designed for OLAP workloads. They are simply different architectures. Therefore, it is impossible to argue that 'OLAP

> And, comparing columnar stores to OLAP cubes is like comparing apples to oranges. The former is a storage format and the latter is an analytical pattern. Modern OLAP cube technology like Kylin/Kyligence stores cubes in columnar st

I know I’m late to the party, but I’ve recently come around to the idea of using apps that sit in front of Postgres to provide an API for free. This seems like an amazing project! I mean, I knew PostgREST existed, but I didn’t realise think

Ahh, my apologies then. Yes, that’s the summary. You’re not the first person to point this out to me, but it turned out that the other reader stopped at ‘A Personal Take’ — which was what I thought happened here! (I was going to look at the

I’m assuming that you didn’t read the section of the essay where I summarise Shanteau, Kahneman and Klein’s findings? Complexity of systems is one aspect, certainly, but valid and regular causal inferences are by far the dominating factor.

I think one of the most interesting things that have come from my study of the decision making literature is that there is a second field that Kahneman respects, that stands opposed to his heuristics and biases (H&B) tradition. The fi

Hey, thanks for the comment! You should probably read the full post, though, as it pre-emptively deals with all three observations you've raised.
