Mac OS X 10.9 Mavericks

Custom recipe to get OS X 10.9 Mavericks running from scratch, setup applications and developer environment. 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.

Install Software

The software selected is software that is "tried and true" --- software I need after any fresh install. I often install other software not listed here, but is handled in a case-by-case basis.

Install from App Store

The introduction to Reactive Programming you've been missing

If you prefer to watch video tutorials with live-coding, then check out this series I recorded with the same contents as in this article: Egghead.io - Introduction to Reactive Programming.

Useful Pandas Snippets

A personal diary of DataFrame munging over the years.

Data Types and Conversion

Convert Series datatype to numeric (will error if column has non-numeric values)

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

Getting box metrics

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

Epictetus

Philosophy is a way of life and not just a theoretical discipline.

Epictetus (55 — 135 AD) was a Greek slave of Rome. He became a great Stoic philosopher and teacher, and was eventually freed.

Although he was a fatalist, he believed that individuals are responsible for their own actions, which they can examine and control through rigorous self-discipline.
