Wow, this is more like a master class on GUI application design than the usual guidelines you see. I don't see a byline but someone poured a lot of love and wisdom into this.

What you are saying is reasonable but it is not what the author proposed. This is your rephrasing: > The point being made isn't that large effects are impossible, or that high-d results should be dismissed outright. But what the aut

"The effect size is too large" seems like a weak heuristic too me. Feynmann talks about the kind of problems such a heuristic can cause: > It's interesting to look at the history of measurements of the charge of an electr

That's interesting. We used Horowitz and Hill as an undergrad and although I didn't continue on the EE track I was under the impression it was the "standard" textbook for introductory electronics. It may be more elementa

These are very beautiful. Very organic, yet strictly mathematical. Many of these techniques have practical applications in computer graphics; see for example https://www.youtube.com/user/keeroyz/videos

Putting a function in front of a backtick string replaces normal string introplation: instead of the default behavior, the function before the backtick string gets passed the literal pieces of the template string and ${} values explicitly

LLVM is quite impressive in terms of software architecture. The use of IR decouples everything and allows optimization passes and backend (machine code generation) to be shared across languages. This also hugely lowers the barrier to entry

It's interesting to draw a parallel between the author's argument that Semmelweis could have achieved more if he had been more respectful and "never antagonized so much of the medical establishment" to similar arguments

My go-to example for high vs. low compositionality is JSON vs. HTTP. JSON has high compositionality - if you want to replace an atomic value with a more complex value, you can use JSON itself to structure the new complex value. Whereas HTTP
