Notes

This code handles any JS runtime error during rendering React components. Without this handling, once an error occurs, whole component tree is damaged and can't be used at all. With this handling, nothing will be rendered in production environment (error span in dev env.) + in production the error is logged to Sentry (if you are not using it just delete related code)
This is basicaly a workaround for proposed feature in React core - described in Issue: facebook/react#2461
Works for all variants of Component creation - React.createClass, extending React.Component and also stateless functional components.
To get this work, just put this snippet into your entry js file. Then it will work in whole application.
Also supporting React Hot Reload!

Ideas

specify custom error renderer (global / per component, e.g. by implementing method renderOnError() in a comp

Keyboard-only Mac Cheatsheet

Hi, I'm Lorna and I don't use a mouse. I have had RSI issues since a bad workstation setup at work in 2006. I've tried a number of extra hardware modifications but what works best for me is to use the keyboard and only the keyboard, so I'm in a good position and never reaching for anything else (except my coffee cup!). I rather unwisely took a job which required me to use a mac (I've been a linux user until now and also had the ability to choose my tools carefully) so here is my cheatsheet of the apps, tricks and keyboard shortcuts I'm using, mostly for my own reference. Since keyboard-only use is also great for productivity, you may also find some of these ideas useful, in which case at least something good has come of this :)

Server scripts

This is the source for the scripts discussed in https://robots.thoughtbot.com/improving-user-experience-with-shell-scripts

Both scripts are in the bin/ directory of the repo that contains all the markdown documents for blog posts. Users run bin/server and everything is automatically set up for them to view a local preview of the blog. bin/server-setup is a dependency of bin/server and is never run directly by users.

Maitre-d is the name of the "blog engine" discussed in the article.
