HOWTO: Create Your Own Self-Signed Certificate with Subject Alternative Names Using OpenSSL in Ubuntu Bash for Window

Overview

My main development workstation is a Windows 10 machine, so we'll approach this from that viewpoint.

Recently, Google Chrome started giving me a warning when I open a site that uses https and self-signed certificate on my local development machine due to some SSL certificate issues like the one below:

Code is clean if it can be understood easily – by everyone on the team. Clean code can be read and enhanced by a developer other than its original author. With understandability comes readability, changeability, extensibility and maintainability.

General rules

Follow standard conventions.
Keep it simple stupid. Simpler is always better. Reduce complexity as much as possible.
Boy scout rule. Leave the campground cleaner than you found it.
Always find root cause. Always look for the root cause of a problem.

How to change your commit messages in Git?

At some point you’ll find yourself in a situation where you need edit a commit message. That commit might already be pushed or not, be the most recent or burried below 10 other commits, but fear not, git has your back 🙂.

Not pushed + most recent commit:

git commit --amend

This will open your $EDITOR and let you change the message. Continue with your usual git push origin master.

SPARQL Queries (with cURL command) on Wikidata

This gist resulted to be just the spark for a proper article, and won't be maintained here anymore.

The SPARQL endpoint is http://wdqs-beta.wmflabs.org/bigdata/namespace/wdq/sparql and it has a Web form to fire queries. However http://www.wikidata.org/prop/direct/P31 ("instance of") tells you what the entity is.

The repository doesn't have named graphs, or at least the SPARQL endpoint rejects graph queries. The classes of entities (rdf:type) are not described in the repository.

To find the HTML page of an entity (such as https://www.wikidata.org/entity/Q866405), simply replace /entity/ with /wiki/.

Installing

Install FFmpeg with homebrew. You'll need to install it with a couple flags for webm and the AAC audio codec.

brew install ffmpeg --with-libvpx --with-libvorbis --with-fdk-aac --with-opus

Application Session Management With OAuth

Fun with AngularJS & Ionic

I don't know about other developers -- but one of the most frustrating things in my mind to get going when starting a new hybrid application is session/authorization management. Do you use OAuth 1, OAuth 2, generic email login, facebook...even thinking about it stresses me out. Unfortunately, no good hybrid (or mobile for that matter) application can escape the need for good authorization (unless it is a stateless app, like a calculator, or something easy).

Personally -- I have come to love the OAuth 2 standard for its simplicity, and standards of operation. It takes some of the stress out of the decision making process when coming up with how to manage application state flow -- something which is especially necessary in [most] mobile (or native) applications. This article is going to focus on one of those pain points -- hybrid mobile app state management, and how to solve it with regards to the marriage of AngularJS & Ion

	Below is a full tutorial on how to setup and use Googles Firebase push notification API for both Android and iOS. It is based on this
	earlier implementation of Googles GCM method: https://gist.github.com/prime31/5675017 - FCM is the new method and GCM will eventually be
	retired.

	## THE BELOW METHOD IS THE NEWER FCM METHOD:

	Register your app in the FCM Console: https://console.firebase.google.com (add project)
	1. Click on the newly added project, in the upper left menu is the "Overview" and Gear Settings.
	2. Click on the GEAR settings icon, and then on "Project Settings"
	3. In the main screen, click on "Cloud Messaging"

	<?php

	class RetryTest extends TestCase
	{
	public function setUp()
	{
	parent::setUp();
	// abuse superglobal to keep track of state
	$_GET['a'] = 0;
	}
