| 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. |
import x from "lodash/fp/x" versus import x from "lodash/x")_set, are wrapped to make a copy first.

| # 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. |

| 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. |
