Ward Christensen, co-inventor of the first computer-based Bulletin Board System, and creator of XMODEM, the first file-transfer protocol designed to work over noisy phone lines (both in the late 1970s), has passed away at the age of 78. He never made a big deal out of his pioneering achievements, and always kept a modest profile in his personal life. <https://arstechnica.com/gadgets/2024/10/ward-christensen-bbs-inventor-and-architect-of-our-online-age-dies-at-age-78/>
