Using wget + grep to explore inconveniently organized federal data (FAA Section 333 Exemptions)

if !database: wget + grep

The Federal Aviation Administration is posting PDFs of the Section 333 exemptions that it grants, i.e. the exemptions for operators who want to fly drones commercially before the FAA finishes its rulemaking. A journalist wanted to look for exemptions granted to operators in a given U.S. state. But the FAA doesn't appear to have an easy-to-read data file to use and doesn't otherwise list exemptions by location of operator.

However, since their exemptions page is just one giant HTML table for listing the PDFs, we can just use wget to fetch all the PDFs, run pdftotext on each file, and then [grep](https://medium.com/@rualthanzauva/grep-was-a-private-command-of-m

requestAnimationFrame helper

raf.js

A simple script with a few niceties that allows for multiple requestAnimationFrame calls, and FPS pinning.

How it works

The script polyfills rAF if required, then overloads requestAnimationFrame and cancelAnimationFrame with a process that allows multiple frames to be queued up for rAF to run.

This is useful if there are multiple animations running on the page, you want all the callbacks to happen at once, and not on multiple rAF calls. This script is meant as a drop-in solution to that problem.

Advanced SCSS, or, 16 cool things you may not have known your stylesheets could do

Advanced SCSS

Or, 16 cool things you may not have known your stylesheets could do. I'd rather have kept it to a nice round number like 10, but they just kept coming. Sorry.

I've been using SCSS/SASS for most of my styling work since 2009, and I'm a huge fan of Compass (by the great @chriseppstein). It really helped many of us through the darkest cross-browser crap. Even though browsers are increasingly playing nice with CSS, another problem has become very topical: managing the complexity in stylesheets as our in-browser apps get larger and larger. SCSS is an indispensable tool for dealing with this.

This isn't an introduction to the language by a long shot; many things probably won't make sense unless you have some SCSS under your belt already. That said, if you're not yet comfy with the basics, check out the aweso
