/*
createReducer() builds a reducer function using an initial state and a map of reducer functions.
Any action whose type matches a key in the reducer map will cause createReducer()'s return value to invoke a method in the reducer map.
If you annotate your dispatch() function as DispatchFor<yourReducerHere>, it will prevent you from passing an event that it's incapable of handling.

Solution to Adam Babcock's brain-teaser

Here's the basic gist of the problem: A principal places one hundred students'
names into one hundred identical boxes, which are sitting in a row in the principal's
office. Each box contains exactly one name, but the names are not guaranteed to
be arranged in any particular order within those boxes.
Students are called in one at a time and are permitted to open up to fifty of
those boxes. If one of the boxes they open contains their name, they get a reward.

# Lockfiles are a feature in Linux which allows multiple processes to use a file as a mutex.

# This script contains example code based on this blog post, but with a bugfix: https://dmorgan.info/posts/linux-lock-files/

# Wrapper function for easy reuse.
# I've heavily annotated it, but without the comments or arguments it's only 13 lines long.
# Parameters (you can hard-code them instead if you want)
# - LOCK_FILE: Which file to use for the lock.

Lodash FP Proposal

• "FP" stands for Functional Programming
• Submodule of Lodash's library (import x from "lodash/fp/x" versus import x from "lodash/x")
• Has a writeup on Lodash's Github page: https://github.com/lodash/lodash/wiki/FP-Guide

Premises

• Immutable: All functions return a copy of the data instead of modifying it. Even functions which normally mutate data, like _set, are wrapped to make a copy first.

Minimal demo of OpenGL >= 3.0, Qt >= 5.0 in Python 3.6

Uses a programmable shader pipeline to draw a pair of triangles.

Eschews PyQt's wrapper functions in favor of PyOpenGL's because I couldn't get it to draw
anything other than a black screen (which means any one of a hundred details were incorrect).
Besides, you'd have to fall back on PyOpenGL to get glDrawArrays anyway, so we may as well
use it for everything.
