Description

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"

Results

A future version of Ember will come with a new templating engine known as HTMLBars.

The original motivation for HTMLBars was to allow helpers and properties to have better contextual information about what they were bound to.

So for example, consider a template like this:

<a href="{{url}}">{{link}}</a>

Better local require() paths for Node.js

Problem

When the directory structure of your Node.js application (not library!) has some depth, you end up with a lot of annoying relative paths in your require calls like:

const Article = require('../../../../app/models/article');

Those suck for maintenance and they're ugly.

An Underscore.js Primer

Written by Darren Torpey and presented to Rue La La in May 2013.

This guide was written based upon Underscore.js version 1.4.4.

What is Underscore.js? How does it help us?

From the official website:

Install

Either copy the aliases from the .gitconfig or run the commands in add-pr-alias.sh

Usage

Easily checkout local copies of pull requests from remotes:

git pr 4 - creates local branch pr/4 from the github upstream(if it exists) or origin remote and checks it out
git pr 4 someremote - creates local branch pr/4 from someremote remote and checks it out

	"default": false

	2. SQL dump (if needed) in database/backups/database_name.sql
	3. CREATE DATABASE and GRANT PRIVILEGES statements for new DB name in database/init-custom.sql
	4. nginx config at /config/nginx-config/sites/my.site.name.conf
	5. nginx config should have a unique server name and point to the www/mynewsite directory
	6. vagrant reload
	7. edit hosts file to point 192.168.50.4 to my.site.name
