Google Chrome Developers says:

The new WOFF 2.0 Web Font compression format offers a 30% average gain over WOFF 1.0 (up to 50%+ in some cases). WOFF 2.0 is available since Chrome 36 and Opera 23.

Some examples of file size differences: WOFF vs. WOFF2

Learnings from working with Open Lighting Architecture for Mac OSX 10.9.5:

On compiling the OLA library from source

Getting the OLA c++ source, compiling it, and running the OLA daemon with Max/MSP to send pixel control data over E131.

I had a lot of initial trouble getting OLA to compile and run on my system. My goal was to eventually control LEDs with DMX/E131 protocol using Max or another client application (built in Openframeworks, Cinder, or Processing).
I found that my library compile problems were coming from Macports. The Official OLA documentation recommends installing with Macports but in practice Homebrew was a better option for me. Here is some info on Homebrew. http://brew.sh/ Once you have homebrew installed, you should be able to run the command brew install ola --universal in your terminal, which will install OLA to /usr/local/Cellar and symlink to /usr/local/lib directory. Sometimes homebrew installs the package but does not link it. You may have to run

Folder Structure

Please note

While this gist has been shared and followed for years, I regret not giving more background. It was originally a gist for the engineering org I was in, not a "general suggestion" for any React app.

Typically I avoid folders altogether. Heck, I even avoid new files. If I can build an app with one 2000 line file I will. New files and folders are a pain.

Hi Nicholas,

I saw you tweet about JSX yesterday. It seemed like the discussion devolved pretty quickly but I wanted to share our experience over the last year. I understand your concerns. I've made similar remarks about JSX. When we started using it Planning Center, I led the charge to write React without it. I don't imagine I'd have much to say that you haven't considered but, if it's helpful, here's a pattern that changed my opinion:

The idea that "React is the V in MVC" is disingenuous. It's a good pitch but, for many of us, it feels like in invitation to repeat our history of coupled views. In practice, React is the V and the C. Dan Abramov describes the division as Smart and Dumb Components. At our office, we call them stateless and container components (view-controllers if we're Flux). The idea is pretty simple: components can't

	$base-font-size: 16px;
	$base-line-height: 1.5;

	// this value may vary for each font
	// unitless value relative to 1em
	$cap-height: 0.68;


	@mixin baseline($font-size, $scale: 2) {

	# There was a day where I have too many color schemes in iTerm2 and I want to remove them all.
	# iTerm2 doesn't have "bulk remove" and it was literally painful to delete them one-by-one.

	# iTerm2 save it's preference in ~/Library/Preferences/com.googlecode.iterm2.plist in a binary format
	# What you need to do is basically copy that somewhere, convert to xml and remove color schemes in the xml files.

	$ cd /tmp/
	$ cp ~/Library/Preferences/com.googlecode.iterm2.plist .
	$ plutil -convert xml1 com.googlecode.iterm2.plist
	$ vi com.googlecode.iterm2.plist
