sina: ben_vulpes: M = [0] * 32

sina: lol...the 2048 bit hash for GPLv2 was taking a really long time so I killed it to add some print statements. Checked "wc -c LICENSE", it reports ~18,000 chars. I re-ran mpfhf with 32 bits, thinking it'd finish at M_pos ~18,000

sina: ben_vulpes: if you count from 0 do we get same hashy hash?

sina: so the step == M_pos

sina: + flip(b, ((i+1 * M_pos) % len(b)))

sina: - flip(b, ((i * M_pos) % len(b)))

sina: ben_vulpes: if I

sina: mircea_popescu: can you confirm/clarify same statement above, start at 0 or 1?

sina: ben_vulpes: also per above my halfscrew won't take any action if the len(a) is 1, can you confirm cl behaviour?

sina: ben_vulpes: as you can see my implementation for screw is only 3 lines long, can you see any faults in it?

sina: ben_vulpes: in your halfscrew I notice (underlying-screw b m-position (floor (/ (length a) 2)))

sina: changing it to the value of the iterator per ben_vulpes cl code fixed it

sina: mircea_popescu: can you confirm/clarify "his operation consists of taking the bit count of either S or R, iterating over that value, at each step multiplying the iterator with the current position in M" ...

sina: mircea_popescu: there was a bug in my screw method which caused the cycle, once I identified it, it stopped cycling

sina: mircea_popescu: nope

sina: mircea_popescu: http://wotpaste.cascadianhacker.com/pastes/U5KgJ/?raw=true 32 1s with 64 bit R_len

sina: mircea_popescu: http://wotpaste.cascadianhacker.com/pastes/kFx6V/?raw=true that is for 64 1s with 64 bit R_len

sina: I feel like my code is now correct, and it no longer loops. However I'm getting different results to ben_vulpes

sina: mircea_popescu: ok thanks

sina: mircea_popescu: earlier you said half screw should round down. In that case, if len is 1 the halfscrew will be 0. so should no iterations be peformed on halfscrew where the len is 1?

sina: thanks ben_vulpes

sina: ben_vulpes: any chance you'd be willing to take a peek at my code>?

sina: mircea_popescu: seems you're correct, "MP kicks3453453453 ass!" still loops

sina: mircea_popescu ben_vulpes http://wotpaste.cascadianhacker.com/pastes/gyrhO/?raw=true assistance appreciated
