asciilifeform: in other news, http://www.washingtonpost.com/world/china-successfully-completes-first-soft-landing-on-moon-in-37-years/2013/12/14/fad6ffb4-64c6-11e3-af0d-4bb80d704888_story.html?tid=pm_world_pop
asciilifeform: got old mr. schwartz complete on 4 floppies.
asciilifeform: mp is the marketing sorcerer, send all related questions/ideas his way.
asciilifeform: why so impatient.
asciilifeform: i did it with pencil, but wrote a compiler of the language to test: http://www.loper-os.org/?p=103
asciilifeform: as far as i'm concerned, they blew it when they went with 'userspace process on top of unix' when designing 'ab initio computer'.
asciilifeform: or, if you deliver prior to payment, simply abscond.
asciilifeform: as if imperial rome hadn't debased coins
asciilifeform: (i see no pads for ROMs, jumpers, or other protection mechanisms in that photo.)
asciilifeform: looks like there are exactly three active components in there
asciilifeform: 'never sends private keys to the computer'
asciilifeform: or simply build separate stations where jumping is officially permitted. hose them down daily.
asciilifeform: why no one simply puts fire alarm-style switches on the track bed wall, is beyond me.
asciilifeform: thestringpuller: holograms? i thought most 'paper wallets' are simply strips of paper crammed into 'arse safes'
asciilifeform: compare with gold standard: geiger counter. http://www.fourmilab.ch/hotbits/statistical_testing/stattest.html
asciilifeform: many consumer widgets do indeed come with silicon that computes sha hash
asciilifeform: 'This week a cluster of VPS that i have been using... ...has been compromised.'
asciilifeform: when the mechanisms used to keep the tens of 1000s of empty foreclosed boxes empty collapse.
asciilifeform: know what'll put a real damper on 'housing bubble' ?
asciilifeform: well yeah, 'TPTB know something we don't' implication
asciilifeform: (and will start emptying coldwallets 'any day now' naturally)
asciilifeform: mp can drop hints if he feels like it.
asciilifeform: they use those for 'through-hole' components.
asciilifeform: phun phact: finally got in the mail: set of vacuum lifter tips. made of high-temp rubber by: Buna! (only ever heard that name in the context of Auschwitz III. had no idea the brand still existed!)
asciilifeform: "an officer without a sword is improperly dressed"
asciilifeform: he had a computer model which explained why certain - helmeted - men ended up with brain damage, while grunts in the same vehicle, sans helmet, didn't.
asciilifeform: or simple good aim (hit same spot twice.0
asciilifeform: 1kJ applied to a head with impenetrable armor -> neck trauma
asciilifeform: let's say 1kJ on impact, for the sake of argument.
asciilifeform: not that such a thing is impossible: medieval Korea had: leather cannon!
asciilifeform: speaking of bizarre: from the text of a spam sample: 'purchase extreme intestinal activity station'.
asciilifeform: a 'strong human' in this context is simply one who knows how to use his machine correctly.
asciilifeform: someone could probably squeeze out a meager living from cracking these chumpatrons.
asciilifeform: basic 'chumpatron.'
asciilifeform: and why only augmentations. let the chumps buy ratpoison for a selected enemy rat.
asciilifeform: what you're probably thinking of (or what you will think of, if you think long enough) is: secure terminal. complete with keyboard and display.
asciilifeform: http://www.nytimes.com/1992/10/21/business/company-news-mattel-says-it-erred-teen-talk-barbie-turns-silent-on-math.html
asciilifeform: perhaps this wasn't mp's motivation in making the choice, but it is a fact nonetheless
asciilifeform: you'll be thankful for the absent css, when you're driving your mpex via telex, from submarine.
asciilifeform: refer to the (admittedly slightly obsolete) spec on mp's site.
asciilifeform: usable, but empty.
asciilifeform: 2023: 'RCMP head Paul Bobson supports organ collection on arrest - Politics - CBC News.'
asciilifeform: buy a simple micro board, make a light blink.
asciilifeform: there is really very little more fun you could have as a programmer, than on a machine that you can completely understand.
asciilifeform: BingoBoingo: complete instruction set: http://ece.wpi.edu/~wrm/Courses/EE2801/Notes/ee2801c00lec20.pdf
asciilifeform: and cancerous complexity in general.
asciilifeform: or simply if you'd prefer a cryptocoin that doesn't degenerate into semiconductor plants as central banks
asciilifeform: self-emptying coldwallets, should they appear, would almost certainly be explained by compromised electronics (airgap that isn't) rather than QM sorcery.
asciilifeform: not to mention that you can craft periodic signals that the canceller will actually amplify.
asciilifeform: why do you suppose the 'legit' exchanges want your government id? precisely to simplify confiscation.
asciilifeform: simple test of your security arrangements. if your PC were to fall into enemy hands, would he know how much BTC you have? (or where.)
asciilifeform: suddenly 'p' (or 'q') is composite.
asciilifeform: man jumps in front of moving bus. considers legal action against bus.
asciilifeform: the fellows who stuffed their gloves with detcord and blew, well, you don't need hands to tramp the dirt
asciilifeform: well in 'democracy' a polizei will bite you on the arse if you employ the unskilled fellow for the wage he's worth.
asciilifeform: flight plan, from the moment of limpeting, should be 'vertical.'
asciilifeform: dub: the hypothetical was: a toystore chopper limpets on to the larger one. what ought to be in the former.
asciilifeform: Vexual: that's nearly an adult chopper, not comparable to the miniatures at all.
asciilifeform: mircea_popescu: same thing that will happen if kermit the frog clamps his teeth around the hand inside his arse and drags it out.
asciilifeform: countdown to when they start fitting employees with Columbian collars...?
asciilifeform: Au would be the champ though
asciilifeform: afaik, his attempt (recently concluded) was to preach to the livestock
asciilifeform: lampshades are conspicuously missing from the catalogue.
asciilifeform: it has to be made of discrete components, that one can reach with a commonplace probe.
asciilifeform: 'nanotech' is a mostly empty 'marketing word.'
asciilifeform: here's an even better idea: vote on chess moves! who needs champions when you've got reddit. no need for the voters to know how to play! 'wisdom of crowds!'
asciilifeform: the people who made off with what remained of the ussr are quite happy campers in london, paris, etc. last i checked.
asciilifeform: i think he was referring to 'QUANTUM' rather than feynman's 'quantum computer.'
asciilifeform: incidentally 'they broke rsa ages ago' makes for a good crackpot theory regarding the wasteful incompetence of, well, everything else. smoke screen.
asciilifeform: jurov: unlike, say, the 'IBM 4764' mysterymeatbag, physical tamper resistance is explicitly not a goal.
asciilifeform: the same people who routinely step into an empty elevator shaft during real quakes.
asciilifeform: fourth piggy lives in a bunker with EMP shield.
asciilifeform: 4. (crackpot) could be wangled into carrying out useful computation (e.g. cryptoanalysis)
asciilifeform: download a fresh copy, right. patched on the fly. ken thompson.
asciilifeform: once the chump is rooted, you can do a million different things.
asciilifeform: over here we have weapons-grade chumpatron fuel.
asciilifeform: mebbe just dumpers doing a splendid job.
asciilifeform: 'лох' - chump, mark, patsy, fool
asciilifeform: (using a Chumpatron reactor.)
asciilifeform: (yield - pumping cost) has to be positive.
asciilifeform: given that: it isn't simply a mass of wire, but step-down stations as well.
asciilifeform: there are even special phone companies for people judged unfit for credit
asciilifeform: people notice the jumps.
asciilifeform: see, when you boil frogs, trick is to use a nice temperature-controlled hob, and not a chinese unit with 'low/high/incinerate' settings on the dial.
asciilifeform: funny thing is, with basic rom-diddling equipment being a dime a dozen now, classic consoles are a great place to learn to program a 'real computer'
asciilifeform: the interesting bit can be reduced to one sentence: "u.s. officials suddenly care about TEMPEST shielding."
asciilifeform: (where people load up cards and sell the complete stripe data on a 'silk road' of sorts)
asciilifeform: specifically: 1) impose ham-handed censorship 2) herd lusers into 'l33t h4ck3r privacy' honeypots 3) '???, profit.'
asciilifeform: ultrasonic is the gold standard test if you don't want to drill/melt the sample.
asciilifeform: example: http://picture.yatego.com/images/47b45967967651.8/big_gcb0-kqh/goldmnzen-tester---gold-coin-balance.jpg
asciilifeform: we had candidate compounds (pharma dev) dissolved in, guess what.
asciilifeform: normally when you get millions of idiots happily jumping, rather than the odd one or two, somebody's built a convenient ramp.
asciilifeform: carried on a correspondence of sort with mp since writing a piece on his creation (http://www.loper-os.org/?p=1108)
asciilifeform: i must remind you, i am not an expert on the mechanics of mpex/mpoe. by all means, ask the author.
asciilifeform: you should probably ask mp to be sure.
asciilifeform: benkay: read the listing (written by mp, not me); there is a promise not to dilute
asciilifeform: pankkake: no idea. ask mp when he wakes up.
asciilifeform: ('available from the Colt Health-Life Insurance and Retirement Savings Company!')
asciilifeform: fiddybucks buys you a 'raspberry' or whatever the pocket computer of the day
asciilifeform: the reason why modern attempts at this are laughable is the state of the credentialling system.
asciilifeform: will be interesting to see 'company towns' where you can get food, housing, etc. for btc.
asciilifeform: i predict: the 'obamacare' software fukkupy will turn into a full-blown 'de-automation' campaign. 'create jobs!' you heard it here phirst.
asciilifeform: it is said that he never spat out his enormous cigar, and once appeared with such near a bomber at a fueling pump
asciilifeform: the cookie jar is far too full for somebody not to try an interesting an unorthodox approach to empty it.
asciilifeform: opc0d3: there are no people here. just a script, running on a PDP-8 drywalled into a closet, door painted over, at NSA campus.
asciilifeform: mod6: once you understand how much of what you presently know will be irrelevant (actually, harmful) after a serious rethinking of computing, you'll shit yourself.
asciilifeform: but never as a foundation for anything claiming to be a 'redesign of computing'
asciilifeform: there is such a thing as an 'impedance mismatch.'
asciilifeform: the idea of implementing something on urbit would be more interesting if the thing actually worked.
asciilifeform: simplest way i can think of is rsa with >2 private primes (lamport, or see MP's writeup)
asciilifeform: mod6: trying to implement provable-share secret-splitting?
asciilifeform: MP, that you?
asciilifeform: point is, some things you don't prevent, you just live with them - and try to set up a world where they aren't especially tempting.
asciilifeform: mircea_popescu: my problem is less with the (truly) extraordinary claims, but the complete lack of any sign of a desire to share the extraordinary evidence.
asciilifeform: btw, some joker wrote a paper (maybe competing for the igNobel?) replicating this on cow carcasses
asciilifeform: VanCleef: say you're trying to catch a bus, and run late. you run after it, and jump, don't quite make it, fall into traffic. the end. buses are a scam?
asciilifeform: lurker: L. Lamport. "The Byzantine Generals Problem."
asciilifeform: there's an undeniable sportsmanship appeal to programming a computer that might kill you, however.
asciilifeform: the newer ones have compartmentalized air supplies for individual lots - a bit like dirigible ballonettes.
asciilifeform: (little buggers all catch something at once. esp. if they're immunocompromised for whatever reason.)
asciilifeform: it's also a game of 'e. coli simply can't be persuaded to piss out X.' or 'croaks trying.'
asciilifeform: computer says '0' or '1'
asciilifeform: that's not even counting non-audio signals that the amp picks up (mains hum, for one)
asciilifeform: for the impatient: it wasn't about crypto per se, but still mandatory.
asciilifeform: so, not poodles? maybe occasionally ill-tempered ones, but where's the bite.
asciilifeform: everybody loves nphard, but the rest of the complexityzoo needs love too
asciilifeform: laughing? it would instantly let you convert, say, btc, into arbitrary parallel computations
asciilifeform: here's an idea: generalize the altcoin concept and bake a turing-complete workfunction spec right into the protocol.
asciilifeform: BingoBoingo: suggest this to MP, that's his department.
asciilifeform: a good HRNG is, probably unavoidably, one of two kinds: that you built yourself, or is simple enough to examine with basic bench instruments to see that it has 'nothing up the sleeve.'
asciilifeform: BingoBoingo: the TI-8x series had serial inputs (3.5mm jack), perhaps you can improvise something.
asciilifeform: the point isn't to build an effective horseless carriage, but to extract money from chumps (including bureaucrats.)
asciilifeform: the aircar pushers aren't idiots, they simply aren't solving the problem you think they're solving.
asciilifeform: speaking of Azerbaijan, has anyone here done the TOR exercise suggested in MP's comments?
asciilifeform: Vexual: if you were to introduce key importation, the zapper would have to come with cyanide.
asciilifeform: mircea_popescu: that was certainly my impression from the link.
asciilifeform: knocking the competing miner offline helps all of the survivors, not just you, though
asciilifeform: (impromptu hack of a translation from russian, originally of a persian rhyme, that i read as a kid.)
asciilifeform: let's say they burn DPR's computer on a pyre in the public square. This would in principle accomplish the same thing.
asciilifeform: "(U) 5. Oppressed Alice, who lives in a repressive country (no or limited free speech) and wants to talk about things contrary to her governments positions. The countries he used as examples were France, Germany (prohibitions on fascist writings?) and the US (not sure what he meant here?)."
asciilifeform: to be fair, there is a long tradition here in the usa of first arming some fellows and then sending armies to bump them off
asciilifeform: and this is completely aside from the 'toilet in the kitchen' problems you get.
asciilifeform: pankkake: js-anything as a security component damns your soul.
asciilifeform: inevitably some moron succumbs to the temptation of buying false papers, he buys from a stoolie; and game over.
asciilifeform: for example, it now is (or soon will be, depending on what document you believe) to sell a car in the u.s. without a remote-disable radio.
asciilifeform: I do wonder why anybody bothered with the 'lettre du cachet', the wiki crap was the equivalent of a winamp playlist
asciilifeform: mircea_popescu: you're probably right that this is a crackpot hypothesis, it presumes competence where, as far as we know, none is left
asciilifeform: makes you wonder what a sober man might've accomplished.
asciilifeform: wtf is the point of ddosing mpex?
asciilifeform: mircea_popescu: i'm just a bit befuddled at the success of the btc chumpatrons
asciilifeform: well, these folks want trust without the reputation of an affair like mpex. so, cryptocontracts (shitcoin, or something more state-of-the-art)
asciilifeform: Duffer1: i suppose the usual idiots bought in? not much of a chumpatron w/out the chumps
asciilifeform: its sort of like the steam-powered automatic doors in ancient egyptian temples
asciilifeform: the chumpatron will keep going without skipping a beat
asciilifeform: a great many interesting things could be done (bring back the turing-complete 'script' engine, for one)
asciilifeform: mircea_popescu: sure btc is ready to lose the chump money collector that is the 'dust' users?
asciilifeform: mircea_popescu: perhaps 'complimentary' means TOR
asciilifeform: you could spend a lifetime studying fun soviet recipes (trinary computer; or my personal favourite, the 'subterrine' - nuclear reactor melts a tunnel in front of you in real time...)
asciilifeform: is there something there other than the chumpatron (gullibility to dollars converter) obvious to a 1st year chemistry student?
asciilifeform: yeah the jumpers. can make it say 'FU', whatever.
asciilifeform: mircea_popescu: you could simply have a thermostat cycle power, a la traditional resistance heaters.
asciilifeform: or is this simply too obvious for an interesting conversation...
asciilifeform: also if your shop relies on 'human compilers,' your soul is damned no matter what.
asciilifeform: mircea_popescu: bad example, most of the boring, everyday Germans survived the war.
asciilifeform: mircea_popescu: quite true, the uniforms and pomp are decorative. think of the 'Zetas' instead. more bang, fewer bucks.
asciilifeform: ah, but at present the best infrastructure is the one built for 'persuasion' of the subjects. and liquidation, if required. the king can always import new ones.
asciilifeform: mircea_popescu: modern figureheads have impeccable manners, but none have taken an agrarian shithole from plow to nuke in a few decades.
asciilifeform: if the pwners of TOR were ready to ditch the deniability of their operation, they could have fed the same exploit to every chump connected to every exit node.
asciilifeform: Kleeck_: that was the payload. nothing to do with the actual compromise
asciilifeform: mircea_popescu: nothing happened that would have required pwning the network. What we got was a perfectly-ordinary server compromise.
asciilifeform: see the now-famous 'TOR incident' as an obvious example. what does one need to have in place of a brain to rely on a winblows box for 'anonymous' naughties?
asciilifeform: if I were the author of the game, and struck with an inexplicable fit of compassion for noobs, I would pop up a dialog showing the user's BTC balance if the binary detects a running bitcoind on the box, saying "boo"
asciilifeform: mircea_popescu: better example: http://www.ticotimes.net/More-news/News-Briefs/Costa-Rica-U.S.-call-for-extradition-law-to-fight-organized-crime_Thursday-May-30-2013
asciilifeform: ever see those temples in India with a sea of live rats in a giant pit?
asciilifeform: the only reason I find this tidbit interesting is that it is yet another example of chumps who think that 'encryption' will save them - without having anything resembling a secure endpoint.
asciilifeform: it does one particular thing: bring in the idiot chumps
asciilifeform: gotta love the compromised 'PGP' (in-browser crap)
asciilifeform: new honeypot: http://www.forbes.com/sites/andygreenberg/2013/06/26/bitcoin-black-market-competition-heats-up-with-pro-marketing-and-millions-at-stake/
asciilifeform: those who refuse to understand bitcoin are doomed to re-implement it.
asciilifeform: mircea_popescu: then both (all) of his bitcoind-with-serial-filed-off will be chumped
asciilifeform: when you use currency minted by an empire, you are buying into its philosophy (if one dare call it that) - like it or not.
asciilifeform: re: the stolen ASIC: here's an idea for improved design: consider an ASIC that needs a "breath of life" packet to run. it would live on a physical key, that must be present on power-up. (can be removed afterwards, assuming battery-backed power.)
asciilifeform: for short-range EMP, the Serbian method ought to work: ordinary kitchen microwaves with a stick jamming the door sensor.
asciilifeform: EMP is a more likely countermeasure. It is quite impossible to adequately shield a small flyer against EM.
asciilifeform: re: compact drones: we are unlikely to see small arms on man-portable flying machines, because Newton's 3rd Law. Plastique is another matter.
asciilifeform: the most accomplished troublemakers should hope for, at most, cut brake cables. or a tragic bathtub slip.
asciilifeform: anybody try this yet? I bet it simply eats the value of the private key.
asciilifeform: 1.5 mil is chump change. That's the cost of ~4-5 ordinary public buses.
asciilifeform: DWave - fake quantum computer, ho hum.
asciilifeform: kakobrekla: I've been trying to reproduce the exact incompetence, for my simulated trader, with no success so far. tried every FP representation I could think of.
asciilifeform: by this logic, teeth are nothing compared to fresh, still-beating hearts.
asciilifeform: recall the fellow in MP's comments who implied that secure systems were used by banks to secure "trillion dollar transactions" ?
asciilifeform: banks, interestingly, don't terribly mind being hackable, because sovereigns can sort of reverse their fuckups for them. and at any rate, they pass the cost onto chumps.
asciilifeform: mircea_popescu: yes, but the false implication is that someone, somewhere on Planet 3 can actually buy a computer. in actual fact, they can only buy a "combuder."
asciilifeform: "The "you don't own your computer" paradigm is not merely wrong. It is violently, disastrously wrong, and the consequences of this error are likely to be felt for generations to come, unless steps are taken to prevent it."
asciilifeform: what most people don't get is that your computer is your priest, doctor, and shrink all in one box: http://glyf.livejournal.com/46589.html
asciilifeform: but when you routinely unearth the plaintext onto potentially-compromised hardware, you are shitting in your kitchen
asciilifeform: my point, though, is that even if you dispense with the convenience of sessions and go the full-bore "hair shirt" with a paper one-time-pad or whatnot, a compromised machine is still a compromised machine.
asciilifeform: but the chumps love it (except when they don't, yes)
asciilifeform: someone should sit with the chump, and patiently explain that mtgox doesn't talk to your yubikey. it talks to your idiot consumer pc that happens to have a yubikey plugged in, and a display that can output whatever your new owner wants it to.
asciilifeform: it not only lets you sell the same machine many times, but passes the security buck to the chump: "oh, you got rooted? your fault, should have patched yourself"
asciilifeform: but in the pc world it is used as an attempt to paper over the fact that the os sucks
asciilifeform: so you can rent a "server" to chumps without actually using one up
asciilifeform: example of the latter: many (most?) xen installs let you set the virtual nic card into promiscuous mode if you root one running os
asciilifeform: to sign mpex messages?
asciilifeform: now you go to a site with routinely botched ssl, like mtgox (at least in the recent past), and then click "what the hell" when your browser complains
asciilifeform: I'll mention one example from places far away. In certain countries, doctored root certs are routinely placed into default ms-windows installs wherever possible.
asciilifeform: my other point is that btc ups the ante for working on hard targets as well as soft ones. you can do some very nice MITM with a compromised router, for instance.
asciilifeform: truecrypt in particular is trivially broken on a compromised machine.
asciilifeform: my only argument, really, is that btc as we know it is a soft target, and that life will become considerably more interesting once the truly competent people take an interest in playing.
asciilifeform: all he has is hope, that some of the chumps will own high-end ATI cards, etc
asciilifeform: I study trojans for money. Most BTC botnets, for example, are quite pitiful (a handful of GH/sec.)
asciilifeform: one more observation: yubi works by emulating usb keyboard. which makes for a very simple man in the middle, esp. if you press the button an extra time.
asciilifeform: also remember that chumps have a tendency to lie to themselves
asciilifeform: mircea_popescu: you evil tempter, you just made me want to transfer btc to mtgox just to buy their yubikey.
asciilifeform: occam's razor suggests that our chump lied about using 2fa
asciilifeform: not into or from the aether, but into a more clever man's pocket, from a chump's.
asciilifeform: the idea is that temporary disruptions can have permanent effect
asciilifeform: a whimper, not a bang.
asciilifeform: jurov: ask MP about his gold bus.
asciilifeform: and not the wimpy FDR confiscation. the Soviet one. where possession of bullion carried the same penalty as murder.
asciilifeform: jurov: re: gold: eventually the physical metals market will decouple from the idiot paper-metal chump harvester. That's when the confiscation gasenwagen revvs up.
asciilifeform: the permanently-unemployed say hello to the kolkhoz, and so on
asciilifeform: what I suspect is that at some point there will be a shift to a rather different, more Latin American social order, where the nobles are simply given bank cards with $ PosInfinity balance
asciilifeform: mircea_popescu: re: 1820: agrarian America, most people did not depend on a working economy as such for physical survival. no comparison.
asciilifeform: I have an FPGA board right here on my desk, with a completely verifiable TCP/IP stack
asciilifeform: the idea would be to have an implementation of BTC which could be understood in its physical entirety.
asciilifeform: 1tb is chump change if you attach mechanical storage.
asciilifeform: the product I envision would be a single-purpose device which runs the block chain and only the block chain. the FPGA code implementing the instruction set, firmware, etc. would form a complete description of the system.
asciilifeform: a system which includes consumer PC components or traditional software is insecure from birth.
asciilifeform: that is to say, a box that implements a full node, from scratch, with no unix/c/c++/code written by anyone in the past on it. with complete docs under NDA.
asciilifeform: mircea_popescu: unrelated thought: do you suppose there could be a market for a hardware implementation of Bitcoin?
asciilifeform: pgp: "fundamental" problem implies that it could not be dealt with other than by breaking the protocol, no?
asciilifeform: btw, the extent to which btc users can be fucked with through ntp spoofing is non-zero and quite interesting to contemplate.
asciilifeform: mpex can afford it
asciilifeform: btw, industrial robots are an instructive example, because in some fields they are available, but it is very difficult to get people to trust them for all but the simplest operations
asciilifeform: example: my colleague prints an iphone cradle, brings in five attempts. the phone fits in the fifth, but only because he threw in the towel and took a hand file to it
asciilifeform: even speaking solely of plastic objects where materials strength is unimportant, the main issue appears to be warping/distortion
asciilifeform: re: 3d printers: I work with a guy who is a serious solid printing enthusiast (five figure investment in various attempts, and most of his spare time.) he prints objects like phone charging cradles and parts for model aircraft.
asciilifeform: "...a paper, JVST A Volume 20, Issue 4, pp. 1365-1368 describing transistors made with anodized aluminum gate insulator and a chemical bath deposited semiconductor (CdS/CdSe). Both are techniques that do not require complicated equipment (beaker, current source, heater) and should have been accessible in the 1920s."
asciilifeform: my point wasn't that it is physically impossible to make small arms out of garbage (it is possible) but that a 3d printer gains you nothing compared to using parts straight from the junkyard.
asciilifeform: mircea_popescu: look up the temperature of the inside of a barrel (of the smallest pistol) after one shot.
