Writing React.js is fun... But being able to draw React components, design responsive layouts and create entire app flows visually can be even more fun! (Especially for those non-coder members of your team who think ECMAScript 6 is a skin disease. They should see the light of React too.)
In this lightning talk, we'll give you a world premiere sneak peek at React Studio (www.reactstudio.com), a GUI tool built specifically for React. We'll explain how React's functional design makes it a great fit for visual tools. Also we will show how React Studio's plugin approach makes it a really powerful meta-programming system. Want to switch your app from Redux to Alt.js or vice versa? Just swap the state plugin and export again! That's just one of the joys of using a visual system for your Reactified visual design.

FFmpeg is one of the most powerful tools for video transcoding and manipulation, but it's fairly complex and confusing to use. That's why I decided to create this cheat sheet which shows some of the most often used commands.
Let's start with some basics:
ffmpeg
calls the FFmpeg application in the command line window, could also be the full path to the FFmpeg binary or .exe file
