GitHub OAuth Busy Developer's Guide

This is a quick guide to OAuth2 support in GitHub for developers. This is still experimental and could change at any moment. This Gist will serve as a living document until it becomes finalized at Develop.GitHub.com.

OAuth2 is a protocol that lets external apps request authorization to private details in your GitHub account without getting your password. All developers need to register their application before getting started.

SchemaSpy is a neat tool to produce visual diagrams for most relational databases.

Here's how to use it to generate schema relationship diagrams for PostgreSQL databases:

1. Download the jar file from here (the current version is v6.1.0)

2. Get the PostgreSQL JDBC driver (unless your installed version of java is really old, use the latest JDBC4 jar file)

3. Run the command against an existing database. For most databases, the schema (-s option) we are interested in is the public one:

# PostgreSQL can be on a remote server but you'll need root privileges in Linux and superuser in PostgreSQL.

# First install build tools

sudo su
aptitude install build-essential
aptitude install postgresql-server-dev-9.4

# Clone and build the PL/pgSQL server-side debugger

Not all random values are created equal - for security-related code, you need a specific kind of random value.

A summary of this article, if you don't want to read the entire thing:

• Don't use Math.random(). There are extremely few cases where Math.random() is the right answer. Don't use it, unless you've read this entire article, and determined that it's necessary for your case.
• Don't use crypto.getRandomBytes directly. While it's a CSPRNG, it's easy to bias the result when 'transforming' it, such that the output becomes more predictable.
• If you want to generate random tokens or API keys: Use uuid, specifically the uuid.v4() method. Avoid node-uuid - it's not the same package, and doesn't produce reliably secure random values.
• If you want to generate random numbers in a range: Use random-number-csprng.

You should seriously consider reading the entire article, though - it's
