I love Tom Scott's computerphile videos. His frustration grows over a few videos; his videos about the difficulties of internationalization[1] and the problems of electronic voting[2] are even crazier. [1] [LINK] [2] [VIDEO]

I love [this video]( [VIDEO] ) from Tom Scott in which he explains quite well why e-voting is inherently bad. I am very happy that here in Switzerland, even if we have to vote several times every year, we still do it the old fashion way :).

Having open source voting systems is a great thing, but electronic voting is inherehently flawed and is a terrible idea. There's no way to prove the checksum of your software is real unless you have root access to the voting machine and are assuming the OS is not compromised. Decentralized electronic machines that print paper ballots for you (which you can physically verify), and submitting to a tabulator seem to be the safest option. But your paper ballot can be compromised in transit by a worker. I have also heard talks about using a blockchain-esque system for voting and verifying it online with a hash code. Here's a great video by Tom Scott: [VIDEO]

Perhaps the most important political message I have seen on XKCD. Related Computerphile episode: [VIDEO] I guess that some computer-powered elections are coming in the US, EU ?

I thought it was nonsense when I first heard it, but the traditional paper system is actually more secure than a completely digital system. Here is a really good video explaining it: [VIDEO]

In europe, voting typically happens in one day, where everyone physically goes to their designated voting place and puts papers in a transparent box. You can stay there and wait for the count at the end of the day if you want to. Tom Scott has a very good video about why we don't want electronic/mail voting: [VIDEO]

I can't see how that in any way can be anywhere near secure enough. Online voting for anything important, is a bad idea. [VIDEO]
