#Setting up Docker Machine on Raspberry PI

SSH into the pi and install docker with curl -sSL https://get.docker.com | sh (If we let Machine try to install the Docker daemon it will fail.)
Change the OS's ID so Docker Machine won't throw errors. sudo nano /etc/os-release and change the line that says ID=raspbian to ID=debian
From a new terminal window run docker-machine create --driver generic --generic-ip-address YOUR-PIS-IP --generic-ssh-key ~/.ssh/id_rsa --generic-ssh-user pi --engine-storage-driver overlay2 MACHINE-NAME

Interestingly Apple doesn't even use Storyboards in their recently open-sourced ResearchKit as [Peter Steinberger has noticed][1] (under the subheading "Interface Builder").

As expected, Apple keeps improving Storyboards and Xcode. Some of the points that applied to iOS 7 and below don't apply to iOS 8 anymore (and are now marked as such). So while Storyboards inherently still have flaws, I revise my advice from don't use to selectively use where it makes sense.

Even now that iOS 7 is out, I would advise ~~against~~ to use caution when deciding whether to use Storyboards. Here are my reasons:

Storyboards fail at runtime, not at compile time: You have a typo in a segue name or connected it wrong in your storyboard? It will blow up at runtime. You use a custom UIViewController subclass that doesn't exist anymore in your storyboard? It will blow up at runtime. If you do such things in code, you will catch them early on, during compile time. Update: My new tool **[StoryboardLin

There are certain files created by particular editors, IDEs, operating systems, etc., that do not belong in a repository. But adding system-specific files to the repo's .gitignore is considered a poor practice. This file should only exclude files and directories that are a part of the package that should not be versioned (such as the node_modules directory) as well as files that are generated (and regenerated) as artifacts of a build process.

All other files should be in your own global gitignore file:

Create a file called .gitignore in your home directory and add any filepath patterns you want to ignore.
Tell git where your global gitignore file is.

Note: The specific name and path you choose aren't important as long as you configure git to find it, as shown below. You could substitute .config/git/ignore for .gitignore in your home directory, if you prefer.

Launch Sublime Text from the command line on OSX

Sublime Text includes a command line tool, subl, to work with files on the command line. This can be used to open files and projects in Sublime Text, as well working as an EDITOR for unix tools, such as git and subversion.

Requirements

Sublime text 2 or 3 installed in your system within Applications folder
