This simple script will take a picture of a whiteboard and use parts of the ImageMagick library with sane defaults to clean it up tremendously.

The script is here:

#!/bin/bash
convert "$1" -morphology Convolve DoG:15,100,0 -negate -normalize -blur 0x1 -channel RBG -level 60%,91%,0.1 "$2"

#Creating your own Gem

Run this command in your Terminal. This creates and names all the files you need for your gem. We are going to create a Lorem Ipsum Generator; you can call it whatever you want but seeing as we are creating a Lorem Ipsum generator we'll call it lorem. Read about gem naming conventions.

	Split an array into chunks and return an array

	With kudos to github.com/JudeQuintana

	This is an update example for code I originally wrote 5+ years ago before
	JavaScript took over the world.

	Extending native objects like this is now considered a bad practice, so use

	# adding and committing
	git add -A # stages All
	git add . # stages new and modified, without deleted
	git add -u # stages modified and deleted, without new
	git commit --amend # Add staged changes to previous commit. Do not use if commit has been pushed.
	git commit --amend --no-edit # Do so without having to edit the commit message.

	# remotes - pushing, pulling, and tracking
	git fetch # gets remote objects and refs. Needed if new branches were added on the remote.
	git remote -v # Lists all remotes (verbose)

	require 'sinatra'

	get "/" do
	erb :form
	end

	post '/save_image' do

	@filename = params[:file][:filename]
	file = params[:file][:tempfile]

	require 'sequel'
	DB = Sequel.connect('postgres://user:pass@localhost/db')
	DB.listen(:my_channel, loop: true) {\|channel, pid, payload\| puts "Got payload '#{payload}' on channel '#{channel}'" }

	git branch -m old_branch new_branch # Rename branch locally
	git push origin :old_branch # Delete the old branch
	git push --set-upstream origin new_branch # Push the new branch, set local branch to track the new remote
