These resources (articles, books, and videos) are useful when you're starting to learn the language, or when you're learning a specific part of the language. This an opinionated list, no doubt. I've compiled this list from writing and teaching Clojure over the last 10 years.

Yoneda (and its duel Coyoneda) is well known in the Category Theory field and has been ported over to functional languages such as Haskell. Each have their uses - sometimes in similar scenarios, also in very different ways.
This will be a newbie's explanation of the concept, using Haskell to illustrate, without any Category Theory.
From what I've read, the Yonedas are not 'daily-drivers' (not used everyday), but rather can be pulled out when the time is right.
Uses: Both Yoneda's can be used to help speed up a program where there are many fmap with long lists or big trees involved. Coyoneda can be used if you want to create an 'interface' and build up calculations, then pass those calculations to an 'executor' to run them.

This gist will show how to setup Raspbian Stretch as a headless Bluetooth A2DP audio sink. This will allow your phone, laptop or other Bluetooth device to play audio wirelessly through a Rasperry Pi.
A quick search will turn up a plethora of tutorials on setting up A2DP on the Raspberry Pi. However, I felt this gist was necessary because this solution is:
- Automatic & Headless - Once setup, the system is entirely automatic. No user iteration is required to pair, connect or start playback. Therefore the Raspberry Pi can be run headless.
- Simple - This solution has few dependencies, readily available packages and minimal configuration.
- Up to date - As of December 2017. Written for Raspbian Stretch & Bluez 5.43
