Atom Clojure Setup

This describes how I setup Atom for an ideal Clojure development workflow. This fixes indentation on newlines, handles parentheses, etc. The keybinding settings for enter (in keymap.cson) are important to get proper newlines with indentation at the right level. There are other helpers in init.coffee and keymap.cson that are useful for cutting, copying, pasting, deleting, and indenting Lisp expressions.

The Atom documentation is excellent. It's highly worth reading the flight manual.

Prerequisites : the letsencrypt CLI tool

This method allows your to generate and renew your Lets Encrypt certificates with 1 command. This is easily automatable to renew each 60 days, as advised.

You need nginx to answer on port 80 on all the domains you want a certificate for. Then you need to serve the challenge used by letsencrypt on /.well-known/acme-challenge. Then we invoke the letsencrypt command, telling the tool to write the challenge files in the directory we used as a root in the nginx configuration.

I redirect all HTTP requests on HTTPS, so my nginx config looks like :

server {

You may want to set up /etc/host such that foo.bar resolves to localhost:5000.

sudo ifconfig lo0 10.0.0.1 alias
echo "rdr pass on lo0 inet proto tcp from any to 10.0.0.1 port 80 -> 127.0.0.1 port 5000" | sudo pfctl -ef -

Then, add this to /etc/hosts:

(def open-for-business? (atom true))
(def haircut-count (agent 0))
(def waiting-room (ref []))
(def waiting-room-size 3)

(defn open-shop [duration]
  (do (Thread/sleep duration) (swap! open-for-business? not)))
 
(defn add-customers []
  (future

   { :f   6 }
   { :c   3 }
   { :d   4 }
   { :g   7 }
   { :h   8 }

My efforts to port http://www.youtube.com/watch?v=f6kdp27TYZs to Clojure.

A boring function (6:22)

func boring(msg string) {
  for i := 0; ; i++ {
    fmt.Println(msg, i)
    time.Sleep(time.Second)
 }
