In Humboldt County, California, a group of volunteers scanned all 65,000 paper ballots using Debian Linux and SANE and counted them independently using Ballot Browser, a free and open source Python program. The group found 200 ballots had been dropped as a result of a four year old bug in the commercial tabulator software.

After the Secretary of State investigated, they also found errors in the commercial software's audit logs, including a user interface button to "Clear" the supposedly unalterable log. Mitch Trachtenberg, the HCETP volunteer who wrote Ballot Browser, will describe the process used in Humboldt, give an overview of Ballot Browser's code, and discuss what other options are available.
