How Space Weather Can Influence Elections on Earth - Motherboard
oh, god -- I'm not keen on this take: how's about designing systems that recognise the risks?
"Everything was going fine, but then suddenly, there were an additional 4,000 votes cast. Because it was a local election, which are normally very small, people were surprised and asked, 'how did this happen?'"

The culprit was not voter fraud or hacked machines. It was a single event upset (SEU), a term describing the fallout of an ionizing particle bouncing off a vulnerable node in the machine's register, causing it to flip a bit, and log the additional votes. The Sun may not have been the direct source of the particle—cosmic rays from outside the solar system are also in the mix—but solar-influenced space weather certainly contributes to these SEUs.
