• draw on PARC resources/tools;
• share results through publications, patents, meetings, and
poster sessions; and
• help create potential business opportunities.
Fellowships are paid, and last about 3 months, typically during the
summer. Graduate-level students—including international students—may

ABOUT THE SUSTAINABILITY FELLOWSHIP
People at PARC are passionate about engaging in sustainable practices
and applying technology toward positive environmental and social
change. The Sustainability Fellowship intersects these two passions.
The Sustainability Fellowship began as a grassroots initiative by
dedicated employees. PARC reduces its own carbon footprint where
possible, and then offsets the remainder, by funding this unique
fellowship program. The goal is to support education—by devoting those
same offset funds to help invent a sustainable future.
Guerrilla's Guide to Optimizing Rails Applications by Alexander Dymo

I was playing around with some unit tests to explore Ruby singleton classes on a recent flight when I decided they could be fleshed out into a pretty nice introduction to some basics of Ruby metaprogramming for those who haven't done much with Ruby (which probably includes most people who've only written Rails applications).
Rails: How we test by Jay Fields
Unit tests are where we test classes in isolation.

Functional Tests
Functional tests are where we verify that all the pieces of the application interact seamlessly.

External Tests
…interact with the external services. Since these tests are slower to run, they are generally only run on the continuous integration server or while debugging a contract change.
