Slate Star Codex discusses postmodernism.
I think Scott actually does a good job explaining some of these concepts. The metaphor at the end is a bit iffy, but overall a nice example of the Principle of Charity.
At the end of the day, the best way to learn postmoderism is to read the postmodernists: Foucault, Deleuze, Derrida, even Merleau-Ponty and Nietzsche.
If you’ve ever designed a database from scratch, or worked with a database migrations, then you know how important it is to get the data schema right the first time. If you get them wrong, then when you (inevitably) have to fix it, you must do a major overhaul of your code just to fit the updated schema. In Rails, this means re-implementing potentially dozens of objects. In Haskell, it’s not as bad because the compiler handles most error checking (with Persistent, anyhow), but it’s still not a trivial exercise.
So how do you design a database with Persistent? You begin with database normalization (DN) in mind.
From The Austrians and the Swan: Birds of a Different Feather by Mark Spitznagel:
To the Austrians, the [economic] process is decidedly non-random, but operates (though in a non-deterministic way, of course) under the incentives of entrepreneurial “error-correction” in the economy. In a never ending series of steps, entrepreneurs homeostatically correct natural market “maladjustments” (as well as distinctly unnatural ones) back to what the Austrians call the evenly rotating economy.
Spitznagel is making the case that the Austrian economists treat the economy as a dynamical system. Rather than a wild beast to be mechanically broken and tamed, it is a quasicyclical system like an ecosystem. This system has attractor states, one of which is runaway inflation. Continue reading
