Ben's VirtualEnv Cheatsheet

This cheat sheet describes my usage/implementation of virtualenv with virtualenv wrapper and the bash foo that I added with the help of many blogs to make it all tick together in fun land.

Quick Reference

$ echo $WORKON_HOME
/Users/benjamin/.virtualenvs

$ echo $PROJECT_HOME

Here is a high level overview for what you need to do to get most of an Android environment setup and maintained.

Prerequisites (for Homebrew at a minimum, lots of other tools need these too):

XCode is installed (via the App Store)
XCode command line tools are installed (xcode-select --install will prompt up a dialog)
Java

Install Homebrew:

ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"

DDD, CQRS and Event Sourcing

In preparation for a new gig I'm reading up on the terms Domain-Driven Design, Command-Query Responsibility Segregation, and Event Sourcing. Here are a list of useful texts and talks that I've discovered so far. If anything is missing please leave a comment.

DDD

Eric Evans: What is a model? - "A model is not a UML diagram nor a certain layer of the software. [...]. It is a system of abstractions, it describes selected aspects of a domain, and can be used to solve problems related to that domain."
Eric Evans: What I've learned since the book - slightly longer talk on Eric's findings since he co-authored the book on DDD.
Eric Evans: Domain-Driven Design - As far as I can tell, the book on DDD. Haven't read it though.

Migrating to OS X Mavericks breaks the ngrep utility. Doing:

sudo ngrep -d lo0 -q -W byline port 8080

stopped working where the process exits immediately. I didn't dig into the ngrep code, but was able to find a simple workaround by doing

sudo ngrep -q -W byline -d lo0 '' 'port 8080'

You can call that a lazy hack, but it work!
