A few years ago I had an encounter with a guy on Quora who was claiming to have invented a way to reverse SHA-256 used in Bitcoin because you can use a SAT solver to do so.
He claimed to having done so.
I was not entirely sure if he had a condition or if he was just trolling. He was technical enough to put the arguments in a way that essentially looks absolutely plausible for someone who is not familiar with the problem.
He's still a puzzle to me.
- TomMarius 8y agoThere is a similarly crazy person who's moderately famous in my country - he claims he has "a much better instant search algorithm way faster than Google", but sadly because of the mafia and the Illuminati and probably also the Jew-freemasons no one wants to give him capital. He is also smart enough to seem to know what he's talking about, knows hard facts about common search algorithms and actually can code. I wonder how does that happen - he is not even trying to foul investors.
- DiabloD3 8y agoI think I've heard of this guy, but theres probably more than one. They describe how to search faster, not produce results faster. Whats really silly is, its already as fast as it needs to be: Google has long since admitted their bottleneck isn't reading all the websites and parsing them (they could point their entire Death Star-esque amount of raw network and disk bandwidth and DDoS the entire Internet at once, every single indexable webserver)... Its actually storing them coherently in their database(s). They have to store them before they can process them (thus reading them back while other storing is happening), and then reading their OTHER database of searchable metadata. Databases Are Hard(tm). Next gen databases like Spanner and BigTable didn't get invented because reading websites was hard (where "better search algos" fits in), but because coherently handling a large database of said fetched results was hard. Actually, it isn't even Databases Are Hard(tm), its the Laws Of Physics Are Hard(tm). 90% of whacko claims I can dismiss because either that, or I'm reasonably sure P != NP.
