Bitcoin Full Node on AWS Free Tier

Provisioning

Launch one T2 micro instance, using Ubuntu 14.04 LTS AMI.
Open SSH and Bitcoin Protocol TCP ports: 22, 8333.
Attach 40GB EBS (General-Purpose SSD) volume for blockchain storage to /dev/sdf.

The pricing should be ~3$ for the first year (assuming 30GB upload per month). See here for more details.

How to configure multiple deploy keys for different private github repositories on the same computer without using ssh-agent

Let's say alice is a github.com user, with 2 or more private repositories repoN. For this example we'll work with just two repositories named repo1 and repo2

https://github.com/alice/repo1

https://github.com/alice/repo2

You need to be to pull from these repositories without entering a passwords probably on a server, or on multiple servers.

Install Apache with Homebrew

Installing Apache

# Start by stopping the built-in Apache, if it's running, and prevent it from starting on boot.
# This is one of very few times you'll need to use sudo:
sudo launchctl unload /System/Library/LaunchDaemons/org.apache.httpd.plist 2>/dev/null

# We need to tap homebrew-dupes because "homebrew-apache/httpd22" relies on "homebrew-dupes/zlib"

and install Apache 2.2 with the event MPM, and we'll use Homebrew's OpenSSL library

C++ Pointer Tutorial

Because pointers can be ugh

"Regular" variables (not pointers)

To understand a pointer, let's review "regular" variables first. If you're familiar with a programming language without pointers like JavaScript, this is what you think when you hear "variable".

When declaring a variable by identifier (or name), the variable is synonymous with its value.

##VGG16 model for Keras

This is the Keras model of the 16-layer network used by the VGG team in the ILSVRC-2014 competition.

It has been obtained by directly converting the Caffe model provived by the authors.

Details about the network architecture can be found in the following arXiv paper:
