File.expand_path('relative/path/to/dir_or_file', '/start/path') # "/start/path/relative/path/to/dir_or_file"

# join seems to be STUPID. It just joins strings (and adds file separator if needed)
File.join('some/path/', '/other/path.rb') # "some/path/other/path.rb"

Product management process with Trello

A Trello board is a software equivalent of a physical wall with columns of sticky notes. In Trello terminology, the wall is called a "board." The columns are called "lists." The sticky notes in columns are called "cards."

No two products are the same, so flexibility in the product management process is important. Trello responds well to changing the structure of the process "on the fly."
