Port Forwarding in Mavericks

Since Mavericks stopped using the deprecated ipfw (as of Mountain Lion), we'll be using pf to allow port forwarding.

####1. anchor file Create an anchor file under /etc/pf.anchors/<anchor file> with your redirection rule like:

OpenVPN on Ubuntu 12.10 at DigitalOcean

Install OpenVPN

sudo apt-get install openvpn

Generate Server Certificates

sudo cp -r /usr/share/doc/openvpn/examples/easy-rsa/2.0 /etc/openvpn/easy-rsa2

cd /etc/openvpn/easy-rsa2

Angular module structure (proposal)

Everyone who's reading this, please leave your opinion/ideas/proposals as a comment for a better world!

Background

Most of you guys read Josh' proposals to make components more reusable, I think. Now, reading through this proposals definitely gives a feeling that this is the right way. Anyways, If you haven't read it yet, you should.

So Josh shows us, how angular apps can be structured in a better and more reusable way. Reusability is a very important thing when it comes to software development. Actually the whole angularjs library follows a philosophy of reusability. Which is why you able to make things like:

This article has been given a more permanent home on my blog. Also, since it was first written, the development of the Promises/A+ specification has made the original emphasis on Promises/A seem somewhat outdated.

You're Missing the Point of Promises

Promises are a software abstraction that makes working with asynchronous operations much more pleasant. In the most basic definition, your code will move from continuation-passing style:

	git clone git://server.com/my-repo1.git

	# After that you need to do some preparations on the source repository, nuking all the entries except the folder you need to move. Use the following command

	git filter-branch --subdirectory-filter your_dir -- -- all

	# This will nuke all the other entries and their history, creating a clean git repository that contains only data and history from the directory you need. If you need to move several folders, you have to collect them in a single directory using the git mv command.
