Mixed Markdown and Shell Scripting

: By the power of this magic string: ex: set ft=markdown ;:<<'```shell' #, this file is now both a markdown document and an executable shell script. chmod +x it and try running it!

The above line does just what it says. More specifically, when placed within in the first 5 lines and preceded only by blank lines or #-prefixed markdown headers:

1. The first part of the magic string makes github and various editors (e.g. atom with the vim-modeline packge) treat the file as having markdown syntax (even if the file doesn't have an extension)
2. The second part (if run in a shell), makes the shell skip execution until it encounters the next ```shell block.

(The line also has to start with a : so that it's valid shell code.)

Serverless plugin author's cheat sheet

This cheat sheet provides a detailed overview of the exposed lifecycle events and available commands (and entrypoints) of the Serverless framework, that can be hooked by plugins (internal and external ones). The document is structured by the commands invoked by the user.

Lifecycle events are shown as the globally available outer events (all providers) and sub lifecycle events that are provider specific in the called order. Currently only the AWS provider is shown. If you have information about the other provider,

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:
