DURHAM, N.C. Seth Kelby Vidal, a ruggedly handsome cyclist and open source software guru was killed Monday, July 8, 2013. He was 36 years old.Seth described himself as a misanthropic humanist. To those who love him, he was a brother, partner, son, mentor, indefatigable curmudgeon, loyal friend and champion for good who believed deeply in community, and worked to improve every one that he was a part of. A constant contrarian and invaluable resource, Seth could build a bike, recommend a restaurant, and upgrade your technology. Seth knew the names of every canine in the neighborhood, and most of their people. He was a brilliant, kind, compassionate, generous, and caring young man whose abilities and knowledge in his field were beyond comprehension. He was known worldwide, and often spoke at conferences in the US and abroad. A wicked storyteller and the consummate travelling companion, he would unabashedly regale road trip cohorts with song. The world will be considerably quieter in his absence.He is survived by his beloved partner, Eunice; his parents, Alicia and Wade; his brother Wade; and sister-in-law Misty; niece-phews, Kelsey and Will; his brother, Logan and his partner, Kate; his grandfather, William Clayton; his grumpy dog, Cori; and countless friends. He lives on in our hearts and the friendships he forged.Services in celebration of his life will be held at Clements Funeral Chapel at 11 a.m. on Saturday, July 13, 2013.The family is being assisted by Clements Funeral Service, Inc. in Durham.
