$ git checkout --orphan NEWBRANCH
$ git rm -rf .

--orphan creates a new branch, but it starts without any commit. After running the above command you are on a new branch "NEWBRANCH", and the first commit you create from this state will start a new history without any ancestry.

You can then start adding files and commit them and they will live in their own branch. If you take a look at the log, you will see that it is isolated from the original log.

Deploying a subfolder to GitHub Pages

Sometimes you want to have a subdirectory on the master branch be the root directory of a repository’s gh-pages branch. This is useful for things like sites developed with Yeoman, or if you have a Jekyll site contained in the master branch alongside the rest of your code.

For the sake of this example, let’s pretend the subfolder containing your site is named dist.

Step 1

Remove the dist directory from the project’s .gitignore file (it’s ignored by default by Yeoman).

// An `Object.observe()` "polyfill" using ES6 Proxies.
//
// Current `Object.observe()` polyfills [1] rely on polling
// to watch for property changes. Proxies can do one better by
// observing property changes to an object without the need for
// polling.
//
// Known limitations of this technique:
// 1. the call signature of `Object.observe()` will return the proxy
//    object. The original object needs to be overwritten with this return value.

Installing gcc 4.8 and Linuxbrew on CentOS 6

The GCC distributed with CentOS 6 is 4.4.7, which is pretty outdated. I'd like to use gcc 4.8+. Also, when trying to install Linuxbrew you run into a dependency loop where Homebrew's gcc depends on zlib, which depends on gcc. Here's how I solved the problem.

Note: Requires sudo privileges.
