EDIT: i gotta admit, you sound like you've got more experience with teaching R than me. so perhaps my opinions here are a bit strong for what they're based on, i.e. tutoring a couple of non-programmer friends and my own learning p

i would recommend getting comfortable with doing stuff with base R, then trying tidyverse. Starting with dplyr might get you results quick, but its "special evaluation" actively confuses your understanding of how the base language

pedantic addendum: looks like i messed up my PEPs -- i linked to PEP622, which was superseded by PEP635 [1]. the gist of it hasn't changed though. --- [1] https://www.python.org/dev/peps/pep-0635/#the-mat

iirc for some reason the amount of antibodies you have falls sharply after 1-3 months and you're vulnerable again. anecdotally, a friend of a friend (EMT) had covid like 4 times before vaccines were available.

a detail that doesn't contradict anything you said but may be useful for someone unfamiliar with it: "avoid success at all costs" is usually meant to be parsed as "avoid [success at all costs]" i.e. don't compr

from a look at the readme, you combine those `$.TYPE` things to build a validation function that checks if its argument matches some pattern (and throws an exception if it doesn't). import * as $ from '@appliedblockchain/

probably because that's a very niche usecase and most people just want some video captions :) (don't get me wrong, what you describe would be cool and useful! but i can't imagine a lot of people would use it)

following the same logic (AFAICT): People self-replicate. People are alive. Societies are composed of people. Therefore, societies are alive. (may or may not be a hole in your argument depending on whether you think a society is "alive

sorry but i feel like this is backwards. the error - incorrectly assuming an `any` will be a `Thing` - is in `getThing`, and that's where the error message should be. getting an error in code that calls `getThing` instead would just ob

i like a nice combinator as much as the next person! but consider this: if python already had multiline lambdas, would you be arguing for using a narrow-purpose combinator instead of `lambda x: foo(x); bar(x)`? [this kind of reminds me of
