# Recently I had to send a password to someone over Skype. Since that's obviously not a good idea, I asked for 
# the person's public SSH RSA key, and used it to encrypt the password itself.


# Convert the public key into PEM format
ssh-keygen -f path/to/id_rsa.pub -e -m pem > ~/id_rsa.pub.pem

# Using the public pem file to encrypt a string
echo "sometext" | openssl rsautl -encrypt -pubin -inkey ~/id_rsa.pub.pem > ~/encrypted.txt

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).

Auto-Deploying via Travis CI

Because Travis CI can automatically execute scripts after successfully (or unsuccessfully!) executing tests, it is an obvious choice for a deployment tool. In order to deploy to a Git repository on a remote server, the process generally is as follows:

• Set up SSH keys
• Add the server's copy of the repository as a Git remote
• Push to the remote
• SSH into the server and execute any installation/compilation/miscellaneous commands

Before even touching .travis.yml...

browserify for webpack users

There's been a strange explosion in misinformation about browserify recently, particularly in comparisons to webpack.

Generally speaking, most of this confusion stems from how webpack is more willing to pull features into its core to ease discoverability while browserify is more likely to push features out to userland instead.

I think that longer-term, separability has more benefits from a maintenance and
