Mac OS X 10.11 El Capitan Setup

Mac OS X 10.11 El Capitan

Custom recipe to get OS X 10.11 El Capitan running from scratch, setup applications and developer environment. This is very similar (and currently mostly the same) as my 10.10 Yosemite setup recipe (as found on this gist https://gist.github.com/kevinelliott/0726211d17020a6abc1f). Note that I expect this to change significantly as I install El Capitan several times.

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. On average, I reinstall each computer from scratch every 6 months, and I do not perform upgrades between distros.

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 own needs.

What forces layout/reflow. The comprehensive list.

What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

Element APIs

  • elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent

Descartes, Berkeley and Functional Reactive Programming

Descartes, Berkeley and Functional Reactive Programming

By @dmvaldman

Functional Reactive Programming (FRP) is generating buzz as an alternative to Object Oriented Programming (OOP) for certain use cases. However, an internet search quickly leads a curious and optimistic reader into the rabbit-hole of monads, functors, and other technical jargon. I’ve since emerged from this dark and lonely place with the realization that these words are mere implementation details, and that the core concepts are far more universal. In fact, the groundwork was laid down many centuries before the first computer, and has more to do with interpretations of reality, than structuring programs. Allow me to explain.

There’s an old thought experiment that goes like this:

Using RxJS instead of Flux with React to organize data flow

Reposted from Qiita

For almost a year now, I've been using this "flux" architecture to organize my React applications and to work on other people's projects, and its popularity has grown quite a lot, to the point where it shows up on job listings for React and a lot of people get confused about what it is.

Why I'm tired of using and teaching flux

There are a billion explainations on the internet, so I'll skip explaining the parts. Instead, let's cut to the chase -- the main parts I hate about flux are the Dispatcher and the Store's own updating mechanism.

If you use a setup similar to the examples in facebook/flux, and you use flux.Dispatcher, you probably have this kind of flow:

// Promise.resolve is good for wrapping synchronous code
