Generate ssl certificates with Subject Alt Names on OSX

Open ssl.conf in a text editor.

Edit the domain(s) listed under the [alt_names] section so that they match the local domain name you want to use for your project, e.g.

DNS.1   = my-project.dev

Additional FQDNs can be added if required:

Generate private key

$ openssl genrsa -out private.key 4096

openssl req -new -sha256 \

Laravel's Dependency Injection Container in Depth

Laravel has a powerful Inversion of Control (IoC) / Dependency Injection (DI) Container. Unfortunately the official documentation doesn't cover all of the available functionality, so I decided to experiment with it and document it for myself. The following is based on Laravel 5.4.26 - other versions may vary.

Introduction to Dependency Injection

I won't attempt to explain the principles behind DI / IoC here - if you're not familiar with them you might want to read What is Dependency Injection? by Fabien Potencier (creator of the Symfony framework).

Accessing the Container

tmux cheat sheet

(C-x means ctrl+x, M-x means alt+x)

Prefix key

The default prefix is C-b. If you (or your muscle memory) prefer C-a, you need to add this to ~/.tmux.conf:

remap prefix to Control + a

CSS Layout Debugger

A tweet-sized debugger for visualizing your CSS layouts. Outlines every DOM element on your page a random (valid) CSS hex color.

One-line version to paste in your DevTools

Use $$ if your browser aliases it:

~ 108 byte version

Virtual Hosts on nginx (CSC309)

When hosting our web applications, we often have one public IP address (i.e., an IP address visible to the outside world) using which we want to host multiple web apps. For example, one may wants to host three different web apps respectively for example1.com, example2.com, and example1.com/images on the same machine using a single IP address.

How can we do that? Well, the good news is Internet browsers

	server {
	listen 80;
	server_name localhost;
	root /Users/YOUR_USERNAME/Sites;

	access_log /Library/Logs/default.access.log main;

	location / {
	include /usr/local/etc/nginx/conf.d/php-fpm;
	}

	services:
	web:
	image: 'redmine:passenger'
	container_name: 'redmine_web'
	restart: always
	ports:
	- '3000:3000'
