Hi there!

The docker cheat sheet has moved to a Github project under https://github.com/wsargent/docker-cheat-sheet.

Please click on the link above to go to the cheat sheet.

This re-styles your sublime text sidebar to be dark, it fits default Monokai theme.

Save the Default.sublime-theme file into packages/Theme - Default, make a backup of your original if you want to be able to go back easily.

Based on:

	That’s one of the real strengths of Docker: the ability to go back to a previous commit. The secret is simply to docker tag the image you want.

	Here’s an example. In this example, I first installed ping, then committed, then installed curl, and committed that. Then I rolled back the image to contain only ping:

	$ docker history imagename
	IMAGE CREATED CREATED BY SIZE
	f770fc671f11 12 seconds ago apt-get install -y curl 21.3 MB
	28445c70c2b3 39 seconds ago apt-get install ping 11.57 MB
	8dbd9e392a96 7 months ago 131.5 MB

	'use strict';

	// simple express server
	var express = require('express');
	var app = express();
	var router = express.Router();

	app.use(express.static('public'));
	app.get('/', function(req, res) {
	res.sendfile('./public/index.html');

	@media (min-width:320px) { /* smartphones, portrait iPhone, portrait 480x320 phones (Android) */ }
	@media (min-width:480px) { /* smartphones, Android phones, landscape iPhone */ }
	@media (min-width:600px) { /* portrait tablets, portrait iPad, e-readers (Nook/Kindle), landscape 800x480 phones (Android) */ }
	@media (min-width:801px) { /* tablet, landscape iPad, lo-res laptops ands desktops */ }
	@media (min-width:1025px) { /* big landscape tablets, laptops, and desktops */ }
	@media (min-width:1281px) { /* hi-res laptops and desktops */ }

	import cv2.cv as cv
	import tesseract
	gray = cv.LoadImage('captcha.jpeg', cv.CV_LOAD_IMAGE_GRAYSCALE)
	cv.Threshold(gray, gray, 231, 255, cv.CV_THRESH_BINARY)
	api = tesseract.TessBaseAPI()
	api.Init(".","eng",tesseract.OEM_DEFAULT)
	api.SetVariable("tessedit_char_whitelist", "0123456789abcdefghijklmnopqrstuvwxyz")
	api.SetPageSegMode(tesseract.PSM_SINGLE_WORD)
	tesseract.SetCvImage(gray,api)
	print api.GetUTF8Text()

	# Assuming an Ubuntu Docker image
	$ docker run -it <image> /bin/bash
