The UNIX shell is a useful environment to get work done. There're a number
of standard, simple tools that talk to each other via a universal
interface: the pipeline. This talk focuses on methods to manipulate and
visualize data directly in the shell, without moving to specialized
environments (numpy, matlab, etc). Specifically I will demonstrate and
describe

feedgnuplot - a tool plot data coming in on STDIN
vnlog - a toolkit to read, write and manipulate columnar ASCII data

These are independent tools that are useful standalone, but with shell
piping are EXTRA useful together and in conjunction with other standard
UNIX tools. This unification of data processing and normal shell usage
enable powerful workflows that are otherwise unavailable.

SPEAKER:

Dima Kogan - Robotics Engineer, Jet Propulsion Laboratory

Dima is a long-time user and contributor to various Free Software projects.
He lives in the shell inside Emacs on his Debian box, and is constantly
looking for ways to save keystrokes. He plays with robotics tools during
the day, and tries to give away as much of his work as possible.
