Sublime Text 2 – Useful Shortcuts (Mac OS X)

Install ImageMagick for image conversion:

brew install imagemagick

Install tesseract for OCR:

brew install tesseract --all-languages

Or install without --all-languages and install them manually as needed.

First create a Ubuntu 13.04 x64 droplet on DigitalOcean Control Panel

Then ssh with root account, run this in termianl:

$ wget -qO- https://raw.github.com/progrium/dokku/master/bootstrap.sh | sudo bash

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"

	I am the owner of lvh.me. And I'm glad to hear it's helpful. In truth, it's just a fancy DNS trick. lhv.me and all of it's sub-domains just point back to your computer (127.0.0.1). That means running ssl is as simple (or difficult) as running ssl on your computer.

	I'm not sure how comfortable you are with the command line, but here's my how I setup my development environment. (rvm, passenger, nginx w/ SSL, etc).


	# Install rvm (no sudo!)
	# ------------------------------------------------------
	bash < <( curl http://rvm.beginrescueend.com/releases/rvm-install-head )
	source ~/.rvm/scripts/rvm
	rvm install ree-1.8.7-2010.02
