Lab 1 should now be in (although you have until Wednesday for
the written part).
Lab 2 Out. We will start promptly at 1:10 PM in TCL 312.
Please be on time. I will be helping you get things set up to use the
Palm Emulators at the start of lab, and it's best if I only have to go
through that once.
Look at shifty product example
