TODO

• psalm
• log viewer

To synchronize local development folder and virtual one, you can use mutagen

• create mutagen.yml

sync:
  defaults:
    flushOnCreate: true
    watch:
      mode: "force-poll"
      pollingInterval: 2
    ignore:
      paths:
        - var/cache
        - node_modules
        - .DS_Store
        - .git
        - .idea
    permissions:
      defaultFileMode: 0666
      defaultDirectoryMode: 0777
  sylar-session:
    alpha: .
    beta: sylar@sylar-dev:/opt/sylar

• add in ~/.ssh/config
