The Goal

Set up Kubernetes on 3 Debian Jessie virtual machines: One master. Two nodes. Additionally do this without any "magic" so that what is required to be running to make everything work is plain and obvious.

We will be using flannel for the inter-machine networking layer. Mainly because it is useful and it seems to be pretty popular.

The Setup

Recently, I decided to migrate my music library from Google Play Music to a self-hosted server running Subsonic. Only problem is I have a bunch of playlists, and Google provides no way to export those into any format that Subsonic can consume (m3u, pls, xspf). I also couldn't find an unofficial tool to do this. The best I could find was a handy app in the Play store called Playlist Backup. It can't export playlists for music stored remotely at Google, but it can create lists of albums and tracks names. Good enough! Now all I needed was a utility that could employ some fuzzy logic to match these lists to my local music files, which follow a typical Artist / Albumn / Track hierarchy.

Turns out, Python 3 makes this really easy! Just copy the script below:

playlist-gen.py:

#!/usr/bin/env python3

# Converts a list of audio tracks

Fading Actionbar

This is a quick example of how to create a fading actionbar effect like this in Appcelerator Titanium

How this works

This is actually very simple. The trick is putting the Actionbar in overlay mode by configuring the theme with windowActionBarOverlay:true. Then all you need to do is updating the color of the Actionbar, in this case by scrolling a ScrollView.

	* Base contract that all upgradeable contracts should use.
	*
	* Contracts implementing this interface are all called using delegatecall from
	* a dispatcher. As a result, the _sizes and _dest variables are shared with the
	* dispatcher contract, which allows the called contract to update these at will.
	*
	* _sizes is a map of function signatures to return value sizes. Due to EVM
	* limitations, these need to be populated by the target contract, so the
	* dispatcher knows how many bytes of data to return from called functions.
