Abstract for Atlanta Docker Meetup

Panamax - Docker Management for Humans

An open-source project that makes deploying complex containerized apps as easy as drag-and-drop.

Join me in discovering Panamax, and find out how its functionality will enhance your use of Docker and simplify common pain points. Docker is good, but Panamax makes it awesome. I will introduce Panamax, and take you on a journey where we will create containerized applications, and then share the applications with our friends. I will also touch upon the basic architecture and underpinnings of Panamax. Panamax is open-source, so you can also learn how to contribute and stay involved as new features are added.

Strings
 
- Parse lines in a String object with #each_line or #lines, instead of #each
- String#ord returns the UTF-8 index
- "x".ord is the new way of doing ?x
- ?a == "a" (and no more "97")
- "A".ord == 65, "ABC".ord == 65
Something went wrong with that request. Please try again.
