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 :)

Apps List

There's more detail on a few of these apps but here is a quick overview of the tools I've installed and found helpful

Discard Ego, Acquire Self Improvement

Be: self aware, disciplined, and humble
Don't: be afraid to ask for help, fear mistakes (learn from them), or get attached to your ideas
Focus on: learning, improving & practicing good habits
Do: well today (and ship) rather than wait for perfection, set high expectations for yourself, step out of your comfort zone, understand and accept you can be wrong, test your code/process/assumptions and ask for feedback

Be Lazy (Practical)

Identify root causes, not what's on the surface
Be clear about your approach and what you're doing/not doing
Differentiate between what needs to be done vs what can be improved later

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

Observable React elements with RxJS

Note: if you want to skip history behind this, and just looking for final result see: rx-react-container

When I just started using RxJS with React, I was subscribing to observables in componentDidMount and disposing subscriptions at componentWillUnmount.

But, soon I realised that it is not fun to do all that subscriptions(that are just updating property in component state) manually, and written mixin for this...

Later I have rewritten it as "high order component" and added possibility to pass also obsarvers that will receive events from component.
