The difference between 2nd and 3rd candidates is 2000 votes. There were 9 million votes in total. That’s insanely close. There is widespread fear that during the recount some votes will be nullified, and some will be changed in some god forsaken villages, resulting in an overturn (which will result in a re-election according to the constitution).
Candidate #1 is a pro russian fascist. #2 is progressive pro-european. #3 is just very corrupt and made a lot of people angry. If #1 goes against #2 in the second round, #2 has a decent chance of winning. #1 against #3 would be really bad, like having to choose between hitler and trump.
I own a Yamaha PSR E403. This series is a lower end class of synthetizer/arranger keyboards targeted towards novice players. Mine also has an identical UI to the one presented here. I wonder if the hack would work on it as well, being a similar model.
My better keyboard is a Yamaha CP88 which is a lot more modern and has updatable firmware. I poked a bit with the update package using binwalk and as far as I could tell it’s not encrypted, and runs some version of QNX. My hacking skills aren’t as good, but I wonder if that one has similar exploits.
