Fix Ubuntu and other Linux slow/hanging file copying via USB.

If your running a x64 bit Ubuntu or other Linux and find USB transfers hang at the end apply this fix:

echo $((16*1024*1024)) > /proc/sys/vm/dirty_background_bytes
echo $((48*1024*1024)) > /proc/sys/vm/dirty_bytes

I suggest you edit your /etc/rc.local file to make this change persistant across reboots.

sudo nano /etc/rc.local

Ruby/Clojure analogs
For each Ruby module/class, we have Ruby methods on the left and the equivalent
Clojure functions and/or relevant notes are on the right.
For clojure functions, symbols indicate existing method definitions, in the
clojure namespace if none is explicitly given. clojure.contrib.*/* functions can
be obtained from,
ruby-to-clojure.*/* functions can be obtained from the source files in this
If no method symbol is given, we use the following notation:
#!/usr/local/bin/sbcl --script
(load (merge-pathnames ".sbclrc" (user-homedir-pathname)))
(ql:quickload "cl-json" :silent t)
(require "inferior-shell")
(defparameter *ssh-user* "ec2-user")
(defparameter *ssh-key-path* "~/.ssh/us-east-1-platform-key.pem")
defmodule BinarySearch do
def find(item, _left, [i | _right]) when i == item, do: true
def find(item, _left, [i | right]) when i < item, do: find(item, right)
def find(item, left, [i | _right]) when i > item, do: find(item, left)
def find(_item, _left, []), do: false
def find(item, list) do
{left, right} = split(list)
find(item, left, right)
