ascii_field: (one of the most accurate timebases found in nature)
ascii_field: decimation measures the time, by observing a pulsar
decimation: a political fiction that for the time being is tied to observable astronomic phenomenon
ascii_field: think of it this way
ascii_field: realize that earth time is a political fiction
decimation: well, yes, but the math is not very difficult to verify
mircea_popescu: i do not dispute they exist. what i said, again, was that if you use a nist table you're basically querying ntp.
decimation: there exist astronomy libraries like http://www.hs.uni-hamburg.de/DE/Ins/Per/Czesla/PyA/PyA/pyaslDoc/pyasl.html that could be used to make such tables
mircea_popescu: how do you get the calibration data ?
ascii_field: mitm can make the answer 1) verify sig correctly 2) be arbitrarily wrong
decimation: as in, a printed table?
ascii_field: realize that we are talking about ~time~
ascii_field: and if it did, hitler could simply delay the packet
ascii_field: but this does not exist today.
mircea_popescu: decimation what i said was that if you use usg-supplied cutouts for that reduction, you're just doing a roundabout ntp call. might as well ask directly
ascii_field: decimation: you can do this, and sign the result with your gossipd key, etc. sure
decimation: nobody has told me why I can't observe the position of the sun in the sky, use today's date, and reduce the time
ascii_field: someone, iirc, discovered that you could move the clock on most 'atm' machines this way
decimation: I'm telling you things I"ve been told
ascii_field: the banks thing really happens
ascii_field: don't even need hitler there. just a kid with an sdr card
decimation: mircea_popescu: all of those could be forged by hitler
ascii_field: anyone recall old thread about banks getting time from gps antennae ?
mircea_popescu: (also telco and radio provider etc)
mircea_popescu: off of their own atomic clock no less
ascii_field: ntp is low-enough traffic that most of the planet asks usg more or less directly
mircea_popescu: last i looked into it my isp actually fed you time, on special port.
ascii_field: conceivably, ~somewhere~ they do
mircea_popescu: they run dns but not time ?
ascii_field: certainly not on this side of the ocean
ascii_field: there is no widespread custom of isp running a time server
decimation: hitler controls time and your isp
mircea_popescu: listen, can't the thing ask the local isp for time ?
mircea_popescu: in other news i am pleased to inform the general public that my pyromania is progressing nicely.
decimation: doesn't need to, treats as man on the street
ascii_field: he can if it treats his signet as ultimate authority
decimation: pogo can record times he observes new blocks since boot
decimation: hitler cannot change the clock on the pogo
mircea_popescu: hardcode http://whattimeitis.com in the cpp
ascii_field: by asking winblows for the time.
decimation: don't need to only rely on the ntp reply
mircea_popescu: you know how satoshi would have solved this problem, rigth ?
decimation: I'm not sure how simple it would be to implement
decimation: well, there is such a thing as signed ntp
ascii_field: and how do you know the answer did not come from satanic isp ?
ascii_field: can ask for time once, yes
ascii_field: decimation: it is well known that you don't
mircea_popescu: to TRUST ntp
decimation: ascii_field: you seem to imply that you need to run ntp daemon to use ntp
ascii_field: rather than the essential
ascii_field: the 1969 thing is an arbitrary aspect of the mechanism
ascii_field: evidently i failed to make the minor point here
mircea_popescu: like the housewives, you know, "oph, i don;t care about the crisis, my husband does all that money stuff" "orly ? shut up and sit down, goose."
ascii_field: just that 'oiled enough'
mircea_popescu: once it comes to it, they care or they go away.
mircea_popescu: ascii_field they don't care now in the manner they don't care about how well oiled their rifle is.
ascii_field: not that virtually no one ~actually cares how many seconds it's been since midnight jan 1 1969~
mircea_popescu: sure. but this does not reflect on timekeeping
ascii_field: lamport's achievement was to abstract out some of the attributes of timekeeping we actually ~need~
ascii_field: sorta the whole point
mircea_popescu: jurov the way you use the cow's teat is not the alpha and omega of what the cow teat is.
assbot: Logged on 07-07-2015 19:14:54; punkman: blockchain doesn't order events based on time
ascii_field: http://log.bitcoin-assets.com/?date=07-07-2015#1191733 << the machine tried to keep folks from 'rewriting history' ☝︎
mircea_popescu: hence rejected blocks from the future.
mircea_popescu: punkman it actually DOES order events to some degree based on time.
ascii_field: mircea_popescu: almost all timekeeping is really for ordering!
punkman: blockchain doesn't order events based on time ☟︎
mircea_popescu: i dunno why people keep mushin them together
mircea_popescu: ordering has jack shit to do with timekeeping
ascii_field: ^ state of the art for p2p ~ordering of events~ - rather than absolute time
mircea_popescu: it is not coincidental that "finance" reduced to hft.
decimation: well, if you only used the sun and the rotation of the earth, you would be ~60 seconds of utc (starting around 1960)
mircea_popescu: unless you discover a more precise clock, and keep it from the enemy, such that you can exploit his misclicks and take his women
mircea_popescu: precision is the problem
jurov: gotta revert to julian calendar?
jurov: "imperial time"
mircea_popescu: and think "hey, my clock can keep time within two hours, how would those newfangled financial traders and hedge funds render me destitute on the cointinent my fathers conquered ?!?!?!"
mircea_popescu: think of time as capital, and think you're that anon president that opposed hamilton
mircea_popescu: you don't appreciate the depth of this problem
decimation: don't need cesium to keep time to 2hr window
ascii_field: but the mystery of building a non-usg and non-usg-pushable political clock remains, afaik, a mystery
mircea_popescu: decimation the human idea of time, yes.
decimation: can't someone in china look at the sky?
ascii_field: jurov: it is at least theoretically possible to build a non-usg network
decimation: I didn't realize that usg owns time now too
mircea_popescu: is what comes tomorrow.
mircea_popescu: the only new thing in the world is the history you didn't know, and the only thing that's worse than what we have today
jurov: actually, we have an usg internet, too
ascii_field: and they aren't sweeping the house, but shitting on the carpet
ascii_field feels like he took that potion from lem's 'futurological congress', which makes one realize that he had no robot servants, just leprous wretches dressed in gabage cans clanking around as 'robots'
punkman: ascii_field: well yeah that was my objection, need to be able to adjust downward
mircea_popescu: and he's picked the dumbest link to do it to
mircea_popescu: basically he could be in government : he's decided to externalise the cost he can't bore
punkman: you could very easily have monotonically increasing target
ascii_field: but not too slowly, and not too quickly
ascii_field: where miners slowly make life harder for themselves
mircea_popescu: punkman he wants to infer the target from the hash.
punkman: mircea_popescu: this dies, because you will find a random block which is 00000000000000000000000000000f and game over. << this is incorrect. you don't infer the target from the hash. 256bit target is included in all block headers.
mircea_popescu: no, we're friends with hilbert, and i don't think it's a bad idea, either.
ascii_field: yes, possibly i triggered somebody's allergy by mentioning a maths dude
