An opinionated list of excellent Clojure learning materials

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.

Peter Thiel's CS183: Startup - Class 1 Notes Essay

Here is an essay version of my class notes from Class 1 of CS183: Startup. Errors and omissions are my own. Credit for good stuff is Peter’s entirely.

CS183: Startup—Notes Essay—The Challenge of the Future

Purpose and Preamble

Every so often I have to restore my gpg keys and I'm never sure how best to do it. So, I've spent some time playing around with the various ways to export/import (backup/restore) keys.

Method 1

Backup the public and secret keyrings and trust database

cp ~/.gnupg/pubring.gpg /path/to/backups/
cp ~/.gnupg/secring.gpg /path/to/backups/
cp ~/.gnupg/trustdb.gpg /path/to/backups/

or, instead of backing up trustdb...

2020/5/31追記: 自分用のメモに書いていたつもりだったのですが、たくさんのスターを頂けてとても嬉しいです。
と同時に、書きかけで中途半端な状態のドキュメントをご覧いただくことになっており、大変心苦しく思っています。

このドキュメントを完成させるために、今後以下のような更新を予定しています。

TODO部分を埋める
書籍を基にした理論・原則パートと、実装例パートを分割
- 現在は4層のレイヤそれぞれごとに原則の確認→実装時の課題リスト→実装例という構成ですが、同じリポジトリへの言及箇所がバラバラになってしまう問題がありました。更新後は、実装時の課題リストを全て洗い出した後にまとめて実装を確認する構成とする予定です。

	/**
	* Negate sideways velocity on an object being acted upon by a Phaser physics engine.
	* The primary use for this is to simulate vehicle movement by negating "drift" when the vehicle turns.
	* @param {Phaser.Sprite} sprite The sprite whose sideways velocity you want to negate
	*/
	function stopSidewaysVelocity(sprite) {
	// Recycle the same object to conserve memory
	if(!stopSidewaysVelocity.sideways) {
	stopSidewaysVelocity.sideways = {};
