On July 6, 2010, PyCon lost a friend when Tim Costello died suddenly. Tim was the uber-technician for CTE , the company that helps the PSF put on PyCon . Tim's first PyCon was Dallas 2007, where he helped run the A/V systems as a favor to Carl Karsten. He has worked at subsequent PyCons, primarily in the background, making the conference infrastructure run smoothly. If you helped set up the networking, volunteered for the A/V crew, or were involved in expo hall setup at a PyCon, you probably worked with him. We offer our deepest condolences to Tim's family, friends, and colleagues. He will be missed. If you would like to show your appreciation for his contributions to the Python Community, Tim's family has asked for donations to the American Heart Association . Tim's obituary appeared in the Chicago Tribune on July 11, 2010.
