Extreme Email Management via GMail Filters

To follow up on my old blogpost http://cosmicrays.wordpress.com/2010/02/25/gmail-workflow/ I now have a refined method-much the same as in the original blog post only more of it: more filters, labels, and inboxes.

The lectures are easy listening (I usually put on my wireless headphones while doing a household chore, and set my iPad somewhere convenient if I need to glance at the slide), although clocking in at about 2 hours a week, are certainly a bit of a commitment.

As such I was nominated to discuss it at our weekly journal club. Here I give a brief review of concepts needed to follow the paper, and then go in depth into how we can use the opinions of multiple lay people as to whether an object is a supernova or not to achieve a highly accurate classification at the expert level.

We had over 30 people at the event, and 3 distinguished guest speakers and judges (including Dr. Prasenjit Saha from my institute, on crowd sourcing gravitational lensing measurements), and an action packed weekend.
