decimation: http://www.insidegnss.com/node/3054 "“We'll be ready to launch the first GPS III in 2015, but it now appears the next generation GPS Operational Control System, or OCX, won't be ready for about a year or two after that,” General William L. Shelton, commander of Air Force Space Command told attendees at the 28th Annual National Space Symposium. "
asciilifeform: i suspect the equipment, protocol, the inescapable 3-ring binders, are all in place.
decimation: http://gpsworld.com/next-gen-gps-ground-control-system-in-question/ "A March 2013 report from the Government Accountability Office (GAO) seems to claim that the projected cost of the next-generation GPS ground-control system, known as OCX, increased by 43 percent, or $1 billion over the past year, to a total cost estimate of $3.7 billion."
decimation: usg can no longer employ/manage to keep the thing running
asciilifeform: sorta one of the places i was going with ntp.
decimation: ^ yeah that's honestly a bigger threat
asciilifeform: anybody's guess whether gps will decay from sat attrition (as glonas did in the 'roarin' 90s' ru) before usa implodes, civilian aviation on its territory Officially ends, and public freebie is turned off
decimation: to the point where it's probably almost unthinkable unless under threat of immediate attack
decimation: hitler would only do this (in a civilized place) at the cost of massive disruption to many things
decimation: yeah I think there are still two encrypted signals
asciilifeform: idea being that hitler can order the public band jammed, when he wants.
asciilifeform: other thing re: gps is that there is ~still~ an encrypted band (as of a few yrs ago, ~two~ separate ones)
decimation: yet along paying $10k for something that can be had for $200 or less
decimation: I wish; I view blowing a few $k on computers and electronics to be a big expense
decimation: admit to owning one?
decimation: "Aircraft conducting WAAS approaches must possess certified GPS receivers, which are much more expensive than non-certified units. In 2006, Garmin's least expensive certified receiver, the GNS 430W, had a suggested retail price of US$10,750.[27]"
decimation: so that gps users can approach 1m accuracy with simple equipment
decimation: ^ attempts to correct for the ionoshere messing with the gps frequency band as it goes through
assbot: Wide Area Augmentation System - Wikipedia, the free encyclopedia ... ( http://bit.ly/1JY9pyq )
decimation: also, that kind of 'correction' is now broadcast from satellite today: https://en.wikipedia.org/wiki/Wide_Area_Augmentation_System
asciilifeform: decimation: there was no money
decimation: surely the ru generals saw the writing on the wall
assbot: Gmane -- Mail To News And Back Again ... ( http://bit.ly/1JY9l1G )
decimation: that tom von baak character is a regular on time-nuts http://dir.gmane.org/gmane.comp.time.nuts
asciilifeform: galileo was also in planning at the time (ru 'glonas' was in a serious state of decay and not relevant) and one legend goes that clinton's order was a failed gambit to sink it ☟︎
asciilifeform: there was a whole industry, almost, devoted to this.
asciilifeform: neatly cancelling out the fuzz
asciilifeform: one interesting aspect of the 'selective availability' era was that folks would actually collect the crud and broadcast... corrections! from an accurately-surveyed point
decimation: and then there's glosnas
asciilifeform: 'give us root or we'll shoot' was the actual statement
asciilifeform: (if anyone remembers the old eu/galileo thread, where usg pissed and moaned about not being given root on galileo)
asciilifeform: clinton's announcement was a little disingenuous - the random noise is gone, yes, and the recent sats don't have it - however they do have option of beam-forming and denying gps to geography of hitler's choice
Vexual: shit bb finds c++, suddenly both wrists show the same time, so is alfs predator time
decimation: interesting selective availability messed with time stability by a factor of 3
assbot: Effect of no SA on HP 58503A GPS Time & Frequency Receiver ... ( http://bit.ly/1L0FeYI )
asciilifeform: http://www.leapsecond.com/pages/saoff << when clinton ordered gps to be made useful to public
asciilifeform: ... or retired and he cut a zero or three of the price tags by repairing with own hands
decimation: he must have a 'golden toilet' job
decimation: wow that's probably at least $500k in equipment
Vexual: BingoBoingo, hows that red/green watch running?
decimation: " A 5071A uses about 50 W at 24 VDC (~2 A)." damn that's alot of battery power
decimation: that's alot of cash to invest in 'diy'
asciilifeform: the traveling clocks against several atomic clocks left at home. Measurements confirmed that the clocks returned 22 nanoseconds ahead in time. ' << try sr at home!
asciilifeform: 'The talk concludes with a first-hand description of Project GREAT, perhaps the ultimate DIY clock experiment. Van Baak methodically selected three of his best portable cesium clocks, outfitted the family minivan (with his wife's permission) as a traveling time laboratory, and drove with his three children up the highest mountain in Washington State. After staying on Mt. Rainier for a long weekend they returned home to compare
decimation: http://rondomvoetbal.nl/jonathan-steelt-punt-van-valleivogels/ apparently there's a paul okkerse who plays soccer
asciilifeform: that list oughta contain ~all~ the 4294967297 folk (see old log as to why)
decimation: Are these more pirate partai types
asciilifeform: used to set the date and time. Not waterproof nor even water resistant. '
asciilifeform: 'The watch keeps time to a few nanoseconds per day. The attractive display is based on 7-segment red LED technology. Batteries are included (they last about 45 minutes but are rechargeable). AC adapter included. There are no adjustments for daylight saving time; however the clock does handle leap seconds and keeps track of the [Modified Julian] date. This HP wristwatch includes 5/10 MHz and 1 PPS outputs. An internal keypad is
decimation: because people use for actual hard timing specs
decimation: yeah that's typical for fpgas
asciilifeform: no less than 4 of'em
decimation: I think I linked an sbc that folks modded for this
decimation: surely the market is nonzero ☟︎
decimation: asciilifeform: the thing that's odd is that this kind of feature isn't 'avaiable for any price'
decimation: also the timing hardware available on typical x86 is usually shitty
decimation: it's rediculous that doesn't exist actually
asciilifeform: superceding the usual clock
asciilifeform always thought that a 'proper' computer oughta include a bnc jack for rb or cesiumfountain on front panel
decimation: note, these are well beyon pedestrian clocks, only for folks who 'need' less than miliseconds per year
asciilifeform: what's the point of rb then
decimation: and quartz typically has better phase noise than rb
assbot: MTI-Milliren Technologies, Inc. ... ( http://bit.ly/1L0yni0 )
decimation: http://www.mti-milliren.com/ocxo_260_ocxo.html < this ocxo is as good as rubidium in terms of thermal stability
assbot: EEVblog #236 - FE-5680A Rubidium Standard Teardown | EEVblog - The Electronics Engineering Video Blog ... ( http://bit.ly/1L0yiLs )
decimation: but admittedly I can't say for sure, and they do have versions of the card with tcxo
williamdunne: ..... this is a thing:
asciilifeform: decimation: that can looks like a normal quartz resonator
asciilifeform: decimation: tube's good for ~decade
decimation: and yeah that cesium standard is cheap - suspiciously so. cesium only lasts so long.
decimation: re: pci ocxo < yeah the ocxo is the metal case in the lower left
mod6: anyway, another thing for the list :]
mod6: well, i guess i kinda got my toe wet with Nock.
mod6: i'll have to give this a try sometime.
BingoBoingo: It's only been a decade since I touched C++ source with anything other than delete key
assbot: Logged on 03-07-2015 17:50:03; phf: i was exploring block storage format, so i wrote some lisp code to read blocks out of .dat in sequence or directly from dumpblock'ed file http://paste.lisp.org/+38JG. i'm not sure where i'm going with it, so i'm leaving it here for interested parties.
asciilifeform: mod6: phf wrote a tx dumper
mod6: fair enough. i guess if it were me, it'd be great start to just dump the block txs to a file or STDOUT or something.
asciilifeform: and not sure if there is a simple way to weasel out of using the rodent here
BingoBoingo ptolly needs to practice C
asciilifeform: mod6: could try
mod6: <+asciilifeform> see forks with own eyes, pop open a block and scroll the tx, etc. << ncurses instead of x11?
asciilifeform: BingoBoingo: the return never happens
asciilifeform: how often is bad tx resulting from the use of some peculiar 'hearnia' ? (on my node - apparently, quite often)
asciilifeform: and how often is the latter a plausible result of bitrot
asciilifeform: who is sending what kind of retarded tx, and why?
asciilifeform: ~another~ interesting scientific instrument would be a fly trap for invalid tx ☟︎
asciilifeform listens to the sound of silence
asciilifeform: see forks with own eyes, pop open a block and scroll the tx, etc.
asciilifeform: oughta be able to watch the 'vital signs' of a node, if one wishes
asciilifeform: ('incoming' in the network may-or-may-not-relay sense, rather than coins sense)
asciilifeform: (tx incoming, tx relayed, blocks...)
asciilifeform: this patch is gonna be a first-class bitch to actually test though..
asciilifeform: this is not seriously important in this case, but it follows 'unix philosophy' in the sense that a proggy returning false lets you use its failure as part of a shell script
asciilifeform: so you'd want to printf and then return false
asciilifeform: BingoBoingo: printf happens to return 1 (true) if it succeeded in printf-ing
asciilifeform: a few other nitpicks. the all-caps convention in bitcoind refers to constants
BingoBoingo: I know nothing better to do
BingoBoingo: Surprised how little change this seems to take vs. 0.9 Bitcoin CORE implementation of flag
BingoBoingo: Actual changes http://dpaste.com/1Y0MG37 will look at actually submitting after more reading and testing and learning process
