There is a certificate course at the UW starting this fall. It is 3 quarters long starting at rubynewb, then rails/web development, then rubyjedi. no, not the real titles. You are not required to take all three courses. do what feels right. To take just one:

There is space available. apparently, plenty of space... so take make this a success, if you are interested or suspect someone you know is interested, PLEASE, help make it happen.

Any chance of this being offered online (http://www.extension.washington.edu/ol/)?
I have the credit card in hand, but nothing in the description clearly states if the class can be taken online. Is it on-campus only? Seattle's a little far from DC...
Nope. Sorry. This class is in person only.
