Rich Already Answered That!

A list of commonly asked questions, design decisions, reasons why Clojure is the way it is as they were answered directly by Rich (even when from many years ago, those answers are pretty much valid today!). Feel free to point friends and colleagues here next time they ask (again). Answers are pasted verbatim (I've made small adjustments for readibility, but never changed a sentence) from mailing lists, articles, chats.

How to use:

The link below in the summary jumps at the answer on this page.
The link on the question itself points back at the original post.

Summary

Lessons learned; The nice and accurate counsel of Alex Miller, programmer

TL:DR

Be intentional
Stay connected to the problem
Use tables to explore alternatives
Make a picture

1. Read the docs!

	Are We There Yet (video)

	Браузерное приложение - расписание встреч. Возможности: добавление встреч, удаление, редактирование.
	На главном экране отображаются все встречи на выбранный день (соответственно есть контрол в выбором даты).
	У встречи есть три состояния: запланирована, в процессе, завершена. Создавать встречи на прошлое запрещено,
	они не должны пересекаться, отображение даты и времени должно быть в часовом поясе браузера.

	Экран добавления встречи: дата и время начала, дата и время окончания, часовой пояс
	(доступны три часовых пояса: Москва, Хабаровск, Гринвич), краткое описание.
	При вводе времени валидировать формат: dd.MM.yyyy hh:mm A, где dd - день, MM - месяц, yyyy - год,
	hh - часы от 1 до 12, mm - минуты, A - AM/PM.

	const selectRandom = numbers => {
	return numbers[Math.floor(Math.random() * numbers.length)];
	}

	const strategy1 = numbers => {
	return numbers[0];
	}

	const strategy2 = numbers => {
	return selectRandom(numbers);

	(defn solve1-1 [x]
	(int (- (Math/floor (/ x 3)) 2)))

	(->> input
	(map solve1-1)
	(apply +))

	(defn solve1-2 [s x]
	(if (<= (solve1-1 x) 0) s
	(recur (+ s (solve1-1 x)) (solve1-1 x))))
