#The Problem We just described standard design issues you have when you start creating layers of services, DAOs and other components to implement an application. That blog/gist is here.

The goal is to think through some designs in order to develop something useful for an application.

#Working through Layers If you compose services and DAOs the normal way, you typically get imperative style objects. For example, imagine the following:

  object DomainObjects {

a simple git branching model

This is a very simple git workflow. It (and variants) is in use by many people. I settled on it after using it very effectively at Athena. GitHub does something similar; Zach Holman mentioned it in this talk.

The gist

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.

Python 2.x

$ python -m SimpleHTTPServer 8000

CasperJS Google Suggest

The script:

/*global casper:true*/
var casper = require('casper').create({
    pageSettings: {
        userAgent: "Mozilla/5.0 (Macintosh; Intel Mac OS X 10.9; rv:31.0) Gecko/20100101 Firefox/31.0"

Scala for comprehension translation helper

"For comprehension" is a another syntaxe to use map, flatMap and withFilter (or filter) methods.

yield keyword is used to aggregate values in the resulting structure.

This composition can be used on any type implementing this methods, like List, Option, Future...

	#!/bin/bash

	# Call with a percentage value from 0 to 100
	# 0 means only red, 50 means half of green and blue is shown through
	# if you don't give any arguments the calibration is cleared

	if [[ -z "$1" ]]; then
	echo Clearing all calibrations
	xcalib -clear
	else
