A Ruby script for collecting phone record statistics from a Facebook user data dump
#! /usr/bin/env ruby
# NOTE: Requires Ruby 2.1 or greater.
# This script can be used to parse and dump the information from
# the 'html/contact_info.htm' file in a Facebook user data ZIP download.
#
# It prints all cell phone call + SMS message + MMS records, plus a summary of each.
#
# It also dumps all of the records into CSV files inside a 'CSV' folder, that is created

Learn how to build a multi-class image classification system using bottleneck features from a pre-trained model in Keras to achieve transfer learning. Tutorial: https://www.codesofinterest.com/2017/08/bottleneck-features-multi-class-classification-keras.html
'''
Using Bottleneck Features for Multi-Class Classification in Keras
We use this technique to build powerful (high accuracy without overfitting) Image Classification systems with small
amount of training data.
The full tutorial to get this code working can be found at the "Codes of Interest" Blog at the following link,
https://www.codesofinterest.com/2017/08/bottleneck-features-multi-class-classification-keras.html
Please go through the tutorial before attempting to run this code, as it explains how to setup your training data.

Fundamentals

Store any kind of data using the following graph concepts:

  • Node: Graph data records
  • Relationship: Connect nodes (has direction and a type)
  • Property: Stores data in key-value pair in nodes and relationships
  • Label: Groups nodes and relationships (optional)

Animated Stroke. The google I/O website this year (https://google.com/io) has some funky animated lettering. I especially liked the animated stroke around the letters and wondered how you might implement that on Android. Turns out that AnimatedVectorDrawable makes this very easy! Here's how it looks: https://twitter.com/crafty/status/71077957997…

Workaround: Connect your Chromecast to a Hotel Wireless Network

About

I recently relocated for new employment. I've been staying in an extended stay hotel for about 3 weeks now. The hotel I'm staying in gives its guests free Wifi access. However, it requires users to accept terms and conditions on a splash page via browser interface before they can use the network. This makes it difficult to use my Chromecast with the network, as it doesn't have a means of accessing that splash page. While I could call the IT help line, I decided to explore a work-around.

Like many networks, my hotel's network attempts to improve security by using MAC address filtering. Luckily, Mac OS X (10.4 - 10.10) makes it very easy to spoof your network card's MAC address.

Here's how to add a devices like Chromecast, AppleTV, Roku to a wireless network that requires a browser to authenticate and accept terms and conditions.

Neo4j directed path through multiple relationships with property filter

Being new to Cypher and Neo4j, I am having trouble constructing my query for my use-case. I am building a simple ACL (access control list) and am looking for a path through permission relationships an up a hierarchy as well. A picture may better explain it:
