Category theory jargon cheat sheet

A primer/refresher on the category theory concepts that most commonly crop up in conversations about Scala or FP. (Because it's embarassing when I forget this stuff!)

I'll be assuming Scalaz imports in code samples, and some of the code may be pseudo-Scala.

Functor

A functor is something that supports map.

import { emptyObject } from 'fbjs/lib/emptyObject';
import { connect } from 'react-redux';
import { pushState } from 'redux-router';
import pure from 'recompose/pure';
import defaultProps from 'recompose/defaultProps';
import doOnReceiveProps from 'recompose/doOnReceiveProps';
import renderNothing from 'recompose/renderNothing';
import renderComponent from 'recompose/renderComponent';
import branch from 'recompose/branch';
import compose from 'recompose/compose';

How I would do it (not in React):

# Make sure you grab the latest version
curl -OL https://github.com/google/protobuf/releases/download/v3.2.0/protoc-3.2.0-linux-x86_64.zip

# Unzip
unzip protoc-3.2.0-linux-x86_64.zip -d protoc3

# Move protoc to /usr/local/bin/
sudo mv protoc3/bin/* /usr/local/bin/

# Move protoc3/include to /usr/local/include/

Tests

✔ Platform [pass: 1, fail: 0, duration: 1ms]
✔ init [pass: 22, fail: 0, duration: 1ms]
✔ emit [pass: 27, fail: 0, duration: 12ms]
✔ emit with context [pass: 42, fail: 0, duration: 5ms]
✔ emit one value - two listeners [pass: 57, fail: 0, duration: 2ms]
✔ emit one value - one listener [pass: 40, fail: 0, duration: 1ms]
✔ emit many listeners [pass: 30, fail: 0, duration: 1ms]

'''This script goes along the blog post
"Building powerful image classification models using very little data"
from blog.keras.io.
It uses data that can be downloaded at:
https://www.kaggle.com/c/dogs-vs-cats/data
In our setup, we:
- created a data/ folder
- created train/ and validation/ subfolders inside data/
- created cats/ and dogs/ subfolders inside train/ and validation/
- put the cat pictures index 0-999 in data/train/cats
