No-one has reported any 'brown paper bag bug' in 2.4.0 as was discovered in 2.2.0. I've been running 2.4.0 for a week now with no problems. The problem with the U.S. election was too much technology, not too little. The Canadian system of hand-counted paper ballots with spaces filled in by pen is scalable, reliable and robust. I shudder to think of the mischief that could be caused by an electronic voting system.
Computer systems are complex and vulnerable to attack.
Computer attacks are devastating in their efficiency. The perpetrators are usually not caught and, often, an attack takes place without anyone even knowing about it. Democracy is too important to be left to computer technology. In my opinion, any electronic voting system must be completely open. That means that anyone should be able to examine any part of the system, from the circuit diagrams all the way up to the source code.
