Bugs from 1843 to the present day
summary
A concise history of notable software failures from 1843 to today, covering Ada Lovelace’s Note G variable-swap bug, Therac-25’s timing and filter-logic errors that caused fatal radiation overdoses, Ariane 5’s signed 64-bit overflow from reused Ariane 4 code, and modern machine-learning mislabeling and exclusion (Google Photos, facial-recognition). The talk links these cases to root causes—wrong assumptions, timing issues, type-conversion errors, and biased data—and shows their consequences: surprising numeric results, financial loss, injury, and social exclusion.
