Comment Not vulnerable in the same ways? (Score 0) 100

'Keccak has the added advantage of not being vulnerable in the same ways SHA-2 might be,'

Out of all the ways a hash function could be vulnerable, not being vulnerable to a few of them hardly looks impressive without more context... But what do I know, I'm not a crytographer.

Indeed. And it's definitely not true that compilers always do a better job of optimizing than humans. Compilers are much better than they used to be, but for certain specific routines they still can't beat an expert Assembly programmer who can try out several strategies in a flexible optimize-benchmark-optimize feedback loop that compilers aren't able to do.

Comment Re:Volume =/= liquidity (Score 1) 325

The end game is probably to trick other traders to think there's a real reason the price is going up, as with all bubbles they have ways to profit from it. But that's just my quick guess.

But I cannot give you definite answers, those algorithms are not public. What is public is the knowledge that they have tricks to find out bid information (via flash orders) which is supposed to be secret. All the side talk about volume, liquidity and price manipulation won't change that...
