mircea_popescu: i dunno why people are so butthurt over how stupid they are. of course they're stupid, nobody smart voted for the guy.
mircea_popescu: ;;later tell smickles any idea why mpexbot chokes on $vwap ^OIX ? everything else works
mircea_popescu: but i can envision when we finally get ai that'll be how s.ai will sell it :
mircea_popescu: even if they live in a sort of gay house, with a house mother, it still takes > 3
mircea_popescu: this, incidentally, is why i see no future for the family of two. by the time all is said and done, living in new york today requires the pooled resources, chiefly intellectual, of about six average kids
mircea_popescu: this is true. merely being retarded is a bar constantly moving up.
mircea_popescu: people certainly haven't well digested nuclear decay, yet
mircea_popescu: actually, perhaps marie curie's experience is a better example.
mircea_popescu: i guess we will likely live to see the best part of it anyway.
mircea_popescu: gravity, fire, these are things that beat so many cavemen across the skull it's ancestral memory
mircea_popescu: no see, because the mains have good precedent in the fire.
mircea_popescu: i doubt the girl's story will actually come i nthat form to the fore.
mircea_popescu: unlike electricity, bitcoin has deep philosophical implications. like say, gravity
mircea_popescu: i suppose going forward this universal subservience of all people, institutions, mechanisms and consjiderations to bitcoin will be the hardest thing for the population to digest.
mircea_popescu: yes asciilifeform , but bitcoin is here to tell academia how to do academia,
mircea_popescu: there must be urgently implemented a pillory system in academia. the top 10% get funding, AND the bottom 10% get tgo spend a day nude with their necks in the thing.
mircea_popescu: blablablaherpderp we know shit, "Until now it has not happened because apparently only very small percentage of active mining devices were switched off on 29 November 2012."
mircea_popescu: "your asics won't be useful anyway by the time anyone gets around to getting changes in that brick it"
mircea_popescu: anyway. this article should be condensed into a two page job application with an asic producer and ditch all the "research" presumptiousness and otherwise opining.
mircea_popescu: perhaps that call was based on the mistaken belief that asics are more durable goods than toilet paper, which has been proven not to hold.
mircea_popescu: this actually was rejected by everyone on the grounds that it makes the stuff so easily brickable by even the slightest cosmetic changes in the "spec" (ie, code) that it's not worth it.
mircea_popescu: Overall we see that we can save 18 additions: 16 additions have a constant equal equal to zero, and 2 more additions with 0x80000000 which can be replaced by flipping one bit, the cost of which is very small (in hardware) when compared to the cost of one addition.
mircea_popescu: anyway, the c oncept of amortised cost of hashes used in efficiency of computation calculations is a sound way to go about things.
mircea_popescu: still the improvements are slight. save 2.x rounds out of 64, that's a 3% gain
mircea_popescu: tho in fairness maybne they were braindamaged/didn't have the time to do it properly
mircea_popescu: because it came out that all the logic needed to do this would actually increased cost and lowered efficiency of the chips
mircea_popescu: this actually has been discussed but not included by at least two asic developers
mircea_popescu: and we can early reject most cases. Only in 1/232 of cases we need to compute 62 rounds in the third compression function. Then only in some 1/260 of cases where we have actually obtained at least 60 zeros, we would need compute the full 64 rounds.
mircea_popescu: We basically want to force values created at rounds t = 60 and 61 to two fixed constants which come from the SHA-256 IV constants, and which would produce zeros at the output. For this most of the time we just need to compute the first 61 rounds out of 64
mircea_popescu: We can reduce the cost factor from 3.0 to 2.0 almost instantly by making the following observation. In the process of bitcoin mining the first compression function does not depend on the random nonce on 32 bits. Therefore we can compute it once every 232 nonces. On average we need
mircea_popescu: statistically speaking it's likely to increase its meaningfullness
mircea_popescu: An interesting peculiarity in Bitcoin specification and source code is that hashing with full SHA-256 is applied twice. This may seem as excessive: one “secure” hash function should be sufficient. It also makes our job of optimizing bitcoin mining substantially more difficult.
mircea_popescu: "We recall from Section 6.2 that new bitcoins can be created when the miner succeeds to hash some data from the bitcoin network together with a 32-bit random nonce and"
mircea_popescu: dude who the fuck writes like this, this is not highschool yet.
mircea_popescu: Back then it was 256 million times easier than today to solve CISO puzzles. Many early adopters of bitcoin have made a lot of money. One of the well-known problems of bitcoin is the problem of hoarding: a substantial proportion of bitcoins in circulation is not used.
mircea_popescu: i'm sorry, this isn't a paper. i'm not sure theverge would publish this muck.
mircea_popescu: "The energy efficiency of bitcoin miners have already been improved by a factor of about 10,000 since bitcoin have been invented, and we claim that further improvements are inevitable. Better technology is bound to be invented, would it be quantum bitcoin miners."
mircea_popescu: "In this paper we point out that there are fundamental incertitudes which depend very strongly on the bitcoin specification and that this is specification is NOT written in stone, it is likely to change"
mircea_popescu: why show bias in the first para when you're trying to play the researcher ?
mircea_popescu: he wants me to boycott "us bitcoin companies" meanwhile his blog runs on google. just that...
mircea_popescu: how they manage to write five pages of nothing that keeps changing every three months but somehow manages to miss that basic point i will never know.
mircea_popescu: the delightful ignorance of these two week old bloggers.
mircea_popescu: nubbins` send Namworld a tshirt with "other people get hotwives and all i have is this lousy hotmail"
mircea_popescu: i wonder if in a coupla years wikileaks type sites will have degenerated to posting unflattering shower pics of elected officials
mircea_popescu: i don't see who can be bothered to read the 5000000 pages of crap governments write
mircea_popescu: kakobrekla ironically, i would guess by now nobody cares anymore
mircea_popescu: basically it's 10x a year, 2012 was an error, shoulda been 30
mircea_popescu: monk takes a sip... sloshes it around, takes another sip and goes
mircea_popescu: so in order to pull a prank on him, some doods get him a glass fulla piss
mircea_popescu: this monk is famous for being able to identify any wine, by the vineyard, even by the vintage in most cases.
mircea_popescu: ya well, then you get slightly better or equal to chance
mircea_popescu: you try and pass contraband by a customs agent with 30 years in the field and tell me.
mircea_popescu: ThickAsThieves it's also bs. humans get close to 100%, provided they're not idiots.
