#Bootstrapping An iOS App

Note: If you're bootstrapping a static lib project, read this gist instead.

##Project Setup

Set devices and iOS target
decide if you're going to use Autolayout (set in the Storyboard > File inspector > Interface Builder Document section)

Secure private web server with NodeJS

This article will explain how to set up a secure web server with NodeJS which only accepts connection from users with SSL certificates that you have signed. This is an efficient way to ensure that no other people are able to access the web server, without building a login system which will be significantly weaker.

I will not explain how to create a certificate authority (CA), create certificates or sign them. If you need to read up on this, have a look at this excelent article on how to do it with OpenSSL (Mac and Linux): https://help.ubuntu.com/community/OpenSSL#Practical_OpenSSL_Usage It is also possible to do this on a Mac with the keychain application, and I assume it is possible on a Windows machine aswell.

This architecture will allow you to have one web server communicating with an array of trusted clients, the web server itself can be on the public internet, that will not decrease the level of security, but it will only ser

Hack on github.com with Kyle Neath

At GitHub, they've set out to GitHub be the best place to share code with friends, co-workers, classmates, and complete strangers.

Already, over three million people use GitHub to build amazing things together.

But that isn't enough. Everyone should enjoy the benefits of Git and everyone should Fork everything.

It turns out GitHub needs your help. You can be GitHub's partner in crime to help Kneath out.

Setting up a SSL Cert from Comodo

I use Namecheap.com as a registrar, and they resale SSL Certs from a number of other companies, including Comodo.

These are the steps I went through to set up an SSL cert.

a simple git branching model (written in 2013)

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.

Update: Woah, thanks for all the attention. Didn't expect this simple rant to get popular.

	BOOL isDark = FALSE;

	CFDataRef imageData = CGDataProviderCopyData(CGImageGetDataProvider(inputImage.CGImage));
	const UInt8 *pixels = CFDataGetBytePtr(imageData);

	int darkPixels = 0;

	int length = CFDataGetLength(imageData);
