asciilifeform: then again, traditional hash algos 'solve' (i.e. pretend to solve) this by 'every sub-op of hashing affects all output bits' which is largely promisetronic.
asciilifeform: !~later tell mircea_popescu while sleeping i had a thought re http://trilema.com/2017/towards-a-better-hash-function and my earlier attempt thereof likewise : that the thing may not in fact be ~collision-resistant~ (it may not be so difficult to take an arbitrary desired output and find a tape that hashes to it.)
asciilifeform: but only the familiar blackhole-catchup-blackhole-catchup cycle.
asciilifeform: ben_vulpes: aaaah, so there were not necessarily any blox mined in 3sec.
asciilifeform: !~later tell ben_vulpes how does mimisbrunnr compute the tslb ? (is it the time block was received on your box ? or some other..?)
asciilifeform: in late 19th c. usa, the land of p.t. barnum & co, there was a (one of many) mass-hysteria crackpotteries, an obsession with 'properly chewing your food before you swallow it.' complete with maxims such as the unforgettable 'nature shall castigate those who don't masticate!' the hayek, rand, etc. folx reminds me of nothing more than of this.

asciilifeform: in other languages, e.g., python, ruby, there is a lesser sin, you end up stuffing multitude of O(n) ops in places where you oughta have O(1), O(n^2) ops where with some thought you could've had O(n), etc. and the braindamage adds up
asciilifeform: davout: in some programming systems, it is very easy to inadvertently ask the machine to solve an np-hard problem. and for 0 good reason, other than that making such a language stroked academitard cocks
asciilifeform: mircea_popescu: it is in fact useful to remember that the 'convenience' of cstring is == to the 'convenience' of shitting on the floor where you stand
asciilifeform: davout: nor null-termed, nor contiguous in memory
asciilifeform: hey if boeing can count an instance of asciilifeform-shown-737-ad as $737price*$p-of-him-buying, and they also get to imagine that the latter is a positive number, >0, then gdp can be trillion!!!1
asciilifeform: it is a lol, picture if you searched 'boeing 737' one time, and then every ad you see after that is for buying one

asciilifeform: incidentally if this were me, i'd make a voyage-only wot key, rate it +1, then at the end, when getting back to home, sign statement 'my voyage key was uneventfully used N times and then incinerated' or 'pygmies stole my voyage key K and signed audacious forgeries F1, F2...' depending on how it went.☟︎☟︎
