12. machine:
    php:
    version: 5.5.11
    Most let you just include a .yml file or similar and
    define your PHP version etc. This is obviously easier
    than setting up Jenkins. Unless you really hate YAML.

14. • Easy to set up, don’t need to deal with that high-maintenance
    butler
    • Don’t need to pay for hosting Jenkins or have it running on a
    box under someone’s desk
    • Can probably run smaller and open source projects for free
    • Automated deployments to many popular tools like Heroku,
    AWS Elastic Beanstalk & Code Deploy, Capistrano, custom
    scripts etc

15. Simple to set up Jenkins alternatives
    • Can be inflexible
    • Need things like Docker support to be added rather than just
    installing it yourself and running a command as part of the or a
    post-build action
    • Limited SCM support for anything but Github (sometimes
    Bitbucket)
    • You may struggle to find one that combines supports for the
    various technologies that you use
    Cons

23. Nodes filtering links
    1. Clicking the single node view icon filters the list down to just that node.
    2. Find nodes with this Tag (e,g just nodes with tagged "www").
    3. Find nodes with this Attribute name (e.g., any node with the "web:pid" attribute).
    4. Find nodes with this Attribute value (e.g., any node with attribute "web:state=RUNNING" ).
