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.

Summary

Set up Jekyll environment on macOS

Set p Ruby, Bundler and a project-level Jekyll on macOS Catalina and up

This guide is for macOS Catalina and is based on the Jekyll on macOS doc and my experience.

1. Install dev tools

Use the XCode CLI to install dev tools. Recommended so that you can install native extensions when installing gems.

	def chk(data):
	x = sum(a + b * 256 for a, b in zip(data[::2], data[1::2] + b'\x00')) & 0xFFFFFFFF
	x = (x >> 16) + (x & 0xFFFF)
	x = (x >> 16) + (x & 0xFFFF)

	View change: Esc + t (each time you do this shortcut a new directory view will appear)
	Print current working directory in command line: Esc + a
	Switch between background command line and MC: Ctrl + o
	Search/Go to directory in active panel: Esc + s / Ctrl + s then start typing directory name
