Shell Revolution

Using the command line is becoming a lost art, but should be one of the most powerful skills in your development arsenal. It is your friend, embrace it. Don't get me wrong, a GUI is great, but it has it's limitations and might not be as robust. You can't automate clicks as easily as you can commands and more times than not, you can just get things done quicker and more efficient. PHP has a great CLI. Use it! This talk will cover common command line tools (screen, grep, awk, cut, mysql, mosh, etc), shortcuts you can take advantage of now, and what you can do to step up your development game.

    THE HARD WAY
    1. Someone new joins your company or team
    
    2. They need to get their development environment setup
    
    3. It takes two days to one week to get up and running
    
    4. Install an IDE
    
    5. Install MAMP or XAMP or something else that can serve pages
    
    6. Make sure the PHP version is the same
    
    7. Make sure the PHP config is the same

    THE HARD WAY
    1. Install additional extensions
    
    2. Configure MAMP
    
    3. Always tackle “it works for me” problems in the environment
    
    4. Environment relies on the local machine. Screwed it up? Do it again.
    
    5. Production environment got updated? Let’s make sure everyone
    updates to the right version, do it again. Sounds fun....

    MY PROCESS
    1. New person shows
    
    2. Install VirtualBox
    
    3. Install Vagrant
    
    4. Clone git repository
    
    5. Run ‘vagrant up’
    
    6. Vagrant uses puppet to boostrap the system using a very similar
    config to production systems
    
    7. Use IDE of choice

    MY PROCESS
    Zero Config for User
    
    1. Apache is using dynamic virtual hosting
    
    2. Local ~/development folder is mapped to /var/www in VM
    
    3. *.dev.emoxie.com points to 192.168.1.50
    
    4. Apache maps the * to /var/www/<*>
