The California Secretary of State's office has just released a report about the situation (PDF) in the November 2008 election in Humboldt County, California (which we discussed at the time). Here's the California Secretary of State's links page on Diebold. The conclusion of the 13-page report reads: 'GEMS version 1.18.19 contains a serious software error that caused the omission of 197 ballots from the official results (which was subsequently corrected) in the November 4, 2008, General Election in Humboldt County. The potential for this error to corrupt election results is confined to jurisdictions that tally ballots using the GEMS Central Count Server. Key audit trail logs in GEMS version 1.18.19 do not record important operator interventions such as deletion of decks of ballots, assign inaccurate date and time stamps to events that are recorded, and can be deleted by the operator. The number of votes erroneously deleted from the election results reported by GEMS in this case greatly exceeds the maximum allowable error rate established by HAVA. In addition, each of the foregoing defects appears to violate the 1990 Voting System Standards to an extent that would have warranted failure of the GEMS version 1.18.19 system had they been detected and reported by the Independent Testing Authority that tested the system.'"
"The algorithm to do that is extremely nasty. You might want to mug
someone with it."
