macOS 10.12 Sierra Setup

Custom recipe to get macOS 10.12 Sierra running from scratch, setup applications and developer environment. This is very similar (and currently mostly the same) as my 10.11 El Capitan setup recipe and 10.10 Yosemite setup recipe. I am currently tweaking this for 10.12 Sierra and expect to refine this gist over the next few weeks.

I use this gist to keep track of the important software and steps required to have a functioning system after a semi-annual fresh install. I generally reinstall each computer from scratch every 6 months, and I do not perform upgrades between releases.

This keeps the system performing at top speeds, clean of trojans, spyware, and ensures that I maintain good organizational practices for my content and backups. I highly recommend this.

You are encouraged to fork this and modify it to your heart's content to match your o

This is a proposal for a lightning talk at the Reactive 2015 conference.

The Joy of Composition

Why stateless rendering is pure bliss

React just got stateless components, meaning that they are in essence pure functions for rendering. Pure functions make it dead simple - even fun - to refactor your views

Rich Hickey on becoming a better developer

Sorry, I have to disagree with the entire premise here.

A wide variety of experiences might lead to well-roundedness, but not to greatness, nor even goodness. By constantly switching from one thing to another you are always reaching above your comfort zone, yes, but doing so by resetting your skill and knowledge level to zero.

Mastery comes from a combination of at least several of the following:

Simple, semi-anonymous backups with S3 and curl

Backing stuff up is a bit of a hassle, to set up and to maintain. While full-blown backup suites such as duplicity or CrashPlan will do all kinds of clever things for you (and I'd recommend either for more complex setups), sometimes you just want to put that daily database dump somewhere off-site and be done with it. This is what I've done, with an Amazon S3 bucket and curl. Hold onto your hats, there's some Bucket Policy acrobatics ahead.

There's also a tl;dr at the very end if you just want the delicious copy-pasta.
