One-line Tree in Python

Using Python's built-in defaultdict we can easily define a tree data structure:

def tree(): return defaultdict(tree)

That's it!

SVG Linear Gradient with D3

This example demonstrates how to use gradients in SVG, defining the stop colors completely via CSS. The advantage of this approach is that we can use gradients in shapes without having to hardcode the stop-color attributes when defining the gradients in the SVG element.

FFmpeg Cheat Sheet for 360º video

Brought to you by Headjack

 
FFmpeg is one of the most powerful tools for video transcoding and manipulation, but it's fairly complex and confusing to use. That's why I decided to create this cheat sheet which shows some of the most often used commands.

 
Let's start with some basics:

• ffmpeg calls the FFmpeg application in the command line window, could also be the full path to the FFmpeg binary or .exe file

Plex Media Permissions for Linux Noobies

There is no problem with being a noobie and I do not use the term to sligtht or disparage anyone.

This is a way to setup your permissions for running Plex in Linux. Different folks may use different methods.

The permissions concepts provided here apply to OSX, but the users and groups are controlled and modified differently, so much of this will not work properly. I think the command is dscl, but that could be out of date.

There are many ways to setup your permissions scheme in Linux, this methodology describes a way to do it, not everyone will like it, but it works for me, so whatever.

If you're using a high-end bluetooth headset on your Macbook Pro it's likely your mac is using an audio codec which favors battery efficiency over high quality. This results in a drastic degradation of sound, the SBC codec is the likely culprit, read more about it here.

Find out what codec you're using

1. Play a song on your headphones
2. Option (⌥) click the Bluetooth button at the top of your screen
3. If you're using AAC or aptX, you can stop here—those are the highest quality codecs.

Change your codec to AAC or aptX
