As a self learner which courses, books, etc have rewired your mental model?

After talking about the biggest failures I have seen through my career in learning JavaScript I watched a YouTube video about an interview with a divorce attorney. It was interesting because the behaviors I heard expressed in that video exactly aligned with behaviors I see expressed in failures to learn after large commitments of time investment in programming. It inspired me to write this: https://github.com/prettydiff/wisdom/blob/master/JavaScript_...

The most important learning for me out of this is that people are predictable and how we commit is modeled by how perceptions of rewards are attained. It also inspired me to dive deeper into self learning about behavior and economics, because people do exceptionally irrational things to avoid perceived discomfort.

I didn't really grok cryptography until I used this:

Part of it was bad teaching -- same lessons over and over til you're exhausted doing ROT13, it's better to do one exercise on paper and have it be the Vigenère cipher or by the time you're covering something beyond the Ovaltine cipher the campers will be too tired to learn.

People focus too much on busywork in these classes, when modern analysis will be done using a computer. Maybe in a SCIF, but... there will be a computer involved.

A few scripts to easily brute force weird shit you find on other people's machines can be useful, or so I've heard -- also who calls it a "kaiser cipher"? Tell me that and I can tell you the answer to Life, The Universe, and Everything.

- Functional Core, Imperative Shell[1] helped me truly grok the paradigm of functional programming.

- Grokking Simplicity[2] then shifted my thoughts on functional programming: it's not about avoiding mutation because mutation is bad. In fact mutation is usually the desired result, but care must be taken because mutation depends on when and how many times it's called.

Mutation is flipping bits in storage, setting pixels on a screen, sending emails: these effects are desired, but it is crucial to only have these effects happen when we want them to, in the order desired, and exactly the number of times we expect.

Compare to pure functions, which simply calculate a value: these can be called whenever, however many times we wish without any major negative consequences. They are much easier to reason about.

However, the two books that rewired my mental model the most were not technical. These books totally altered my overall mindset:

1. Conversations with God[3]. Best answers for biggest questions in life; answered better than any religion; actually resolves all the conflicts between different religions:

- What is the meaning of life?

- How did the universe begin?

- Why do bad things happen to good people?

- What happens after we die?

2. Direct response marketing. (I coined the term "precision marketing" to differentiate from the "brute force marketing" usually conjured when people hear the word "marketing.") Lots of different resources; Start from Zero[4] is a good one. Expert Secrets[5] is a well-written collection of direct response marketing's greatest hits.

Wow! I didn't know that Shriram's introductory course had lecture videos available. I will take a look at them.

Btw, I also liked Hubbard and Hubbard.

Another book I liked was Computer Systems: A Programmer's Perspective at https://csapp.cs.cmu.edu/
