14 tools and gems every Ruby developer would love

This is a very good list. A few things I hadn't seen before but will instantly add to my project.

Hirb is great when inspecting elements in the console. It's a mini view framework for IRB/Console. It can handle displaying information in tables and pages. It's not quite powerful enough to build a full fledge TUI application, but it's really useful for quickly inspecting data in the console. Say you want to print the attributes of the last 10 signed in users. Hirb would let you display them as a table instead of a bunch of long lines, It makes it a lot easier to visually parse information. It's not Rails-specific but comes with Active Record support out of the box.

Looks like a worthy successor to one of my favorite gems, table_print.
