BingoBoingo: Blackbag operation against the groundhog stealling all of the soon to be tomatoes last week was satisfying
decimation: wonder how many backyard warriors are planning on killing the neighbor's kids while "defending" their home with an ak?
BingoBoingo: asciilifeform: Now we're talking
BingoBoingo: Plastic ratshot still messes drywall. Also... I want it for the challenge. Not smashing spiders with a weapon capable of felling a snake
decimation: it's actually quite elegant, rids you of the need to come up with some silly signed integer representation
assbot: Balanced ternary - Wikipedia, the free encyclopedia
decimation: http://en.wikipedia.org/wiki/Balanced_ternary "Donald Knuth has pointed out that truncation and rounding are the same operation in balanced ternary ? they produce exactly the same result (a property shared with other balanced numeral systems). "
BingoBoingo: mircea_popescu: There are still WWI era Springfields that are in nice shape, but with the Enfields... "British Industry" producers of fine cars that have a commonality with puppies in their leaving of puddles
assbot: Ternary computer - Wikipedia, the free encyclopedia
asciilifeform: ternary cpu was not only space-efficient (closer to 'e', more compact arithmetic representation) but considerably simplified arithm. circuits.
decimation: and the american machines were already "new jersey" style
asciilifeform: mircea_popescu: i might have mentioned this once, long ago. what killed? the decision to copy american machines to run warez.
assbot: Online Emulation of Soviet Ternary Computer Setun / rinary
decimation: I find that amusing, perhaps when the 'end of moore' comes, ternary computers will reappear
decimation: I was reading about the history of computers the other day ascii - early soviet machines were balance ternary!
assbot: Baggage X-ray machine part 6 - inside the black box. - YouTube
decimation: Yeah I bet you need a good vaccuum too
asciilifeform: love how they eventually admitted that it was a '50s russian discovery
assbot: Sticky tape generates X-rays : Nature News
asciilifeform: hard to get detector that is sensitive enough
asciilifeform tried to build the famous scotch tape xray
decimation: nah, use scotch tape
asciilifeform: aye, whack a tungsten target with electron. bremsstrahlung!
decimation: now imagine what kind of chance the average airport mouthbreather has to figure things out
decimation: most good engineers would have alot of trouble figuring out circuitry from an xray (in a short timeframe)
asciilifeform: xray tube hasn't really changed since it was discovered.
mircea_popescu: what do trhese things use, high voltage diode ?
mircea_popescu: dignork o wow he did that ?
dignork: the guy made a long film out of it, but he managed to turn it on, and then was brave/stupid enough to disassemble particle emitter
cazalla: mircea_popescu: there is a new exchange here in au, cointree.com.au, i emailed and invited them here, they were happy to meet for coffee or do a google hangout but no show here :\
asciilifeform: lol re: baggage machine. used to push my knapsack through this exact type of box every morning.
mircea_popescu: and gotta keep pumping them "news"
mircea_popescu: cazalla the disadvantage of running a neobee is that you get the "no news" people on your case
decimation: this guy on the UK side was having a field day http://en.wikipedia.org/wiki/Craig_Harrison_%28sniper%29
cazalla: zhoutong is getting into the atm card business https://www.coinjar.com/dna
asciilifeform: naturally, 'massaged' mosins, not the usual surplus market
decimation: well sure, but they have $100 to spend on pashtoon ak or enfield :)
mircea_popescu: in that sense they need sniper rifles not frigging enfields.
decimation: afghanistan is the ideal long-distance shooting country
mircea_popescu: decimation "the half dozen or so men moved several hundred meters away and drew lots to see who would fire in what order."
asciilifeform: russia produced millions of them, and they can be had in original crate (!) for about 100 usd.
mircea_popescu: What was not noticed much outside of Afghanistan, was that this shift in weaponry brought to an end a long Afghan tradition of precision, long range shooting.
mircea_popescu: diametric not bad. i like your guy better than the agilent guy
asciilifeform: decimation: looked solid in the film.
decimation: I think the mu-metal is used to line the outer plastic chassis
BingoBoingo: Futbol would be a lot more interesting if the World Cup's championship game was just Klose and Messi taking shots from the goal line for 90 minutes
decimation: I suspect the gaskets are something like this http://www.chomerics.com/products/emi/gaskets/wovenwires/index.html
[]bot: Bet placed: 4.79 BTC for No on "World Cup top scorer to net > 7" http://bitbet.us/bet/905/ Odds: 9(Y):91(N) by coin, 29(Y):71(N) by weight. Total bet: 33.06780078 BTC. Current weight: 6,488.
asciilifeform: the dissector fellow ought to have known this.
mircea_popescu: this is why if i managed him i'd only take final customer items.
gribble: Mu-metal - Wikipedia, the free encyclopedia: <http://en.wikipedia.org/wiki/Mu-metal>; MuShield Magnetic Shielding / MuMetal Home Page, the leader in ...: <http://www.mumetal.com/>; MuMETAL® Sheet and Foil On Magnetic Shield Corporation: <http://custommagneticshielding.magneticshield.com/category/mumetal-sheet-and-foil>
decimation: I can't find any comments about the gaskets, youtube sucks
decimation: this was probably a demo unit, if the agilent sales guys gave it to him
decimation: " It's not unusual for the first couple of units to have components changed by designers who are not expert solderers just to prove that the mod works as intended. Once everyone is happy then some of these units become demo models, "
assbot: EEVblog #470 - Agilent N9344C 20GHz Spectrum Analyser Teardown - Page 3
decimation: on the guy's forum someone talks about the bodge wires: http://www.eevblog.com/forum/blog/eevblog-470-agilent-n9344c-20ghz-spectrum-analyser-teardown/msg233302/#msg233302
mircea_popescu: ahaha solder reinforced dead trace ?
mircea_popescu: someone leave him the comment he asks for ?
decimation: heh thru-hole parts with hand-drawn pcbs
asciilifeform: for anyone overcome with urges, there's an emulator somewhere, if i recall.
decimation: heh yeah that's the autonetics deal
decimation: computers could be built this way, if people were willing to pay for it
asciilifeform: it is only a surprise to folks who were never left alone with them
asciilifeform: serious lab instruments usually look quite like this on inside.
decimation: yeah this video is unusally good for this guy, usually he just rambles at the camera for an hour rather than showing the goods
mircea_popescu has learned a lot this past half hour
decimation: plus it is simple to field upgrade
decimation: that way they don't have to slow down assembly line with firmware burner
decimation: yeah I just saw what you were talking about, the one in the middle of the board is to load new firmware
mircea_popescu: decimation since not populated nor intended to open i imagined it's factory diagnosis ?
asciilifeform: doubt the bodges are in the analogue nets
mircea_popescu: so "attention to detail" agilent is full of random wires lol
decimation: the sd slot is probably to store pretty pictures of the spectrum you capture
decimation: the max "resolution bandwidth" for the device is only 3 MHz, that's the width of its filter as it tracks over 20 GHz
decimation: I think agilent makes "genesis" which does exactly this
asciilifeform: decimation: not necessarily. usually these patterns are crapped out by software.
decimation: hehe yeah those "pcb waveguide" filters are awesome
assbot: EEVblog #470 - Agilent N9344C 20GHz Spectrum Analyser Teardown - YouTube
BingoBoingo: mike_c: Close to, but...
BingoBoingo: mike_c: You asymmetric seeding of the pot this round may have fucked you https://btc.waroflife.com/gow/16/
asciilifeform: note (e.g. at 47 minutes) the pcb-as-passive-component trick
decimation: yeah that's why all the shielding (preventing logic spurious signals)
mircea_popescu: asciilifeform amorpous metal will process similarly, just takes longer
mircea_popescu: decimation i thought the claim was 20ghz of bw
decimation: typically you sweep from low to high frequencies of interest
decimation: it makes an image of the spectrum, sampled over a period of time
decimation: it's not really an oscilloscope, doesn't need to have 20 ghz of bandwidth
mircea_popescu: look at some of the examples of ancient gemcutting, you'll be impressed.
mircea_popescu: <asciilifeform> but go make the die for shells with file. << women, diamond dust, fingers.
mircea_popescu: what, they use 500 of the things ?!
mircea_popescu: which'd be the scam.
mircea_popescu: but they claim to be differen
asciilifeform: take N independent adc, and stagger the sampling phases
mircea_popescu: <decimation> heh yeah the a/d converter next to the 'bodge wires' is only 40 MHz 12-bit << wtf. so 20ghz is a scam ?
asciilifeform: but go make the die for shells with file.
decimation: or titanium knives
mircea_popescu: <asciilifeform> i see nothing in there that couldn't be milled on an ordinary desktop cnc machine. << this.
decimation: it would be fairly straightforward to disassemble & repair, unlike macbook air for example
decimation: what's interesting is how modular and easy to take apart this agilent device is
asciilifeform: there are other ways to figure out that you're 'far from kansas.'
