<DocScrutinizer05> seems my cat been one of the 25% that are immune against catnip. It also wasn't useable as tobacco, so eventually I stopped watering it
<DocScrutinizer05> ;-P
<DocScrutinizer05> (the catnip, not the cat)
<DocScrutinizer05> then OTOH my cat been crazy without catnip, every now and then
<DocScrutinizer05> she loved potato peel for example
<whitequark> you tried to smoke catnip?
<DocScrutinizer05> really went crazy for it, digging it out from bottom of filled kitchen wastebin
<DocScrutinizer05> sure
<DocScrutinizer05> :-)
<whitequark> ...
<whitequark> okay
<whitequark> well
<DocScrutinizer05> tastes not really delicious and has no psychoactive properties whatsoever
<whitequark> that explains
<whitequark> everything, I guess
<DocScrutinizer05> lol
<DocScrutinizer05> I heard in WW-II they smoked seagrass form mattresses
<DocScrutinizer05> can't figure it tastes better or works better than catnip
<whitequark> I humbly suggest you have a vacation in Colorado
<DocScrutinizer05> tumble weed?
<DocScrutinizer05> nah, I'll stay with tobacco for rest of my life
<whitequark> (... which if you do, won't be that long)
<DocScrutinizer05> sometimes I think it's been long enough
<whitequark> :/
<DocScrutinizer05> anyway I'm not one of those longevity fanatics
<DocScrutinizer05> "live fast, die young" been the motto of our generation
<DocScrutinizer05> I'm allready much older than I planned to get
<whitequark> I don't know, I'd surely rather die than spend last 20 years of my life in some nursery being demented
<whitequark> but for all I know, modern medicine makes it possible to be of sound mind in 70s
<DocScrutinizer05> right
<whitequark> look at Vint Cerf
<whitequark> the guy's still very much kicking it
<whitequark> and probably will for at least a decade, maybe more
<DocScrutinizer05> look at Mick Jagger ;-P
<whitequark> or Knuth. I wonder if he ever finishes his massive manuscript
<whitequark> well, that's not too bad either!
<whitequark> damn, now I wonder how exactly catnip would taste if smoked
<DocScrutinizer05> anyway, when I send s mail to some folks saying "you wanna administrate your infra yourself? Good luck! prepare for that infra to go down!" and then one idiot comes and accuses me I had threatened them with me "formatting the servers", then I really wonder if life isn't too long maybe
<DocScrutinizer05> whitequark: smoke peppermint tea and you know it
<DocScrutinizer05> (too long) generally or either for me or those guys
<DocScrutinizer05> ;-)
<DocScrutinizer05> generally, since it obviously leaves time for dealing with such BS, or for either them or me since otheriwse we hadn't run into this situation
<whitequark> yeah, figured it'd do something with maemo
<whitequark> I certainly hope you have backups and a proven method for restoring them
<whitequark> dunno how it was done, but we youngsters have a newfangled method for managing infra, called "chef". basically you describe your infra in a domain-specific language, then you give it a blank server and within 10min you have exactly what you described
<whitequark> or you modify your chef config and rerun it, and get your actual config updated
<whitequark> especially useful if you have 1000s of servers
<wpwrak> DocScrutinizer05: well, your statement could be interpreted as vote of extreme lack of confidence or as a threat. since they seem to be quite confident of themselves, they jumped to the latter ...
<wpwrak> DocScrutinizer05: but it seems to be a task you want to get out of. let them fight. you have much more important things to do.
<wpwrak> whitequark: now i'm wondering if "chef" is a tool, a person, or some metaphysical form of existence :)
<whitequark> chef is a program
<wpwrak> there go my dreams of jeannie ...
<whitequark> it's written in ruby, and there's a penchant for certain kind of naming in the ruby community
<whitequark> e.g. chef operates on recipes, and the command-line tool for creating recipes is called knife
<wpwrak> of course, she wouldn't need 10 minutes. it would fail spectacularly, but at least it would be done in the blink of an eye
<whitequark> a collection of recipes is a cookbook, which is stored in a bookshelf... and so on
<wpwrak> ah, speaking of failure. here's a picture of a launch the argentina space program calls "successful": http://www.lanacion.com.ar/1669921-un-despegue-fallido
<whitequark> lol
<whitequark> what
<whitequark> it's a very liberal definition of "successful"
<wpwrak> at least it didn't explode, which is something
<pcercuei> lol
<wpwrak> but the "snout in the dirt" posture gives it a rather comical appearance
<wpwrak> DocScrutinizer05, larsc: i can say it better in german "die Rakete fiel auf die Fresse" ;-)
<DocScrutinizer05> The requested operation could not be completed
<DocScrutinizer05> Cyclic Link Detected
<wpwrak> works here. maybe try again ?
<DocScrutinizer05> I however have a pretty clear idea how it looked like, seen same pictures from V2 development and I think also from early USA space program
<DocScrutinizer05> wpwrak: you're using FF I guess. It's more forgiving for such BS
<wpwrak> (works here) even with konqueror :)
<DocScrutinizer05> o.O
<wpwrak> naw, i use chromium
<whitequark> wpwrak: did it even ignite?
<DocScrutinizer05> prolly you got cookies enabled then
<wpwrak> whitequark: i thing there is something that looks like minor scorch marks. but yes, i asked myself that question, too. it may well have just fallen off the ramp ;-)
<wpwrak> ah yes, cookies i have
<DocScrutinizer05> whitequark: yeah that happens when it ignites but stops or significantly reduces thrust after a very short time
<DocScrutinizer05> or even just one of several engines lifts the whole rocket on one side
<DocScrutinizer05> while other ones don't work
<DocScrutinizer05> there are several funny movies of V2 and other rockets lifting from start table ~50cm, then sinking down again, falling to the side and exploding in a giant fireball
<whitequark> yeah, giant fireballs are invariably a side effect of immature rocketry
<whitequark> no wonder you're so attracted to it :p
<wpwrak> DocScrutinizer05: you want to watch this: http://www.youtube.com/watch?v=McbCwSW2moo
<wpwrak> i especially likes the one towards the end that lifted off just enough to smash down with good enough force to blow of massively
<DocScrutinizer05> yeah the first one already of your link, typical
<wpwrak> it gets better :)
<larsc> It is amazing that they managed to get rockets of the ground at all without modern computing power
<DocScrutinizer05> 2:50 - rocket folds itself
<DocScrutinizer05> LOL
<DocScrutinizer05> there's a reason you call it "rocket science"
<wpwrak> larsc: but then, some of the finest disasters were actually possible only thanks to computers :)
<wpwrak> looks more like "rocket empiricism", though :)
<nicksydney> wpwrak: STM32 Cortex-M0 now selling for 32cents https://www.youtube.com/watch?v=FQMPa0kr-RA :)
<larsc> this is so much better than the exploding rockets http://www.youtube.com/watch?v=HXdjxPY2j_0
<DocScrutinizer05> 11:50 classical
<DocScrutinizer05> 11:58 rather
<DocScrutinizer05> 50cm jump and BOOOM
<wpwrak> larsc: yeah, that one was impressive
<DocScrutinizer05> real video art
<DocScrutinizer05> only thing missing: a real grasshopper crwling across the camera lens, sometime after the cows moved by
<DocScrutinizer05> anyway the test itself is based on utterly useless a concept
<DocScrutinizer05> you can't use this concept for anything meaningful
<DocScrutinizer05> http://www.youtube.com/watch?v=McbCwSW2moo 13:37 is extremely funny
<DocScrutinizer05> dang, 13:57
<DocScrutinizer05> nope
<DocScrutinizer05> 13:30 it starts
atommann_ has joined #qi-hardware
<wpwrak> yeah, looks for a moment as if it would go after the sub ;-)
<wpwrak> and 27:40 illustrates what a darwin award candidate would do :)
<wpwrak> me, i'd rather politely excuse myself at the first sign of trouble and cowardly retire behind the next blast wall
xiangfu has joined #qi-hardware
<DocScrutinizer05> yeah, darwin award warranted
<wpwrak> even the last one is kind dramatic, even though they seem to have maintained a much safer distance
<DocScrutinizer05> well, safe distance is always relative, see castle bravo
<DocScrutinizer05> "duh, those are 30% Li6 and 70% supposedly inactive Li7 in there, a 40km distance should suffice by far"
<whitequark> well, one can also overdo safety
<DocScrutinizer05> then find yourself confronted with the largest explosion (western) humans ever managed to set off
<whitequark> and get todays nuclear industry, stuck with 60-year-old designs where new could be more efficient, less wasteful *and* eventually safer
<whitequark> DocScrutinizer05: eh? no, largest would be Tsar Bomba, 100Mt reduced to 50Mt
<whitequark> Castle Bravo is mere 15Mt
<DocScrutinizer05> "we could see the bones through our hands' flesh"
<whitequark> oh, western. yes
<wpwrak> western like in wimps :)
* whitequark thinks "western" as in "not china or japan"
atommann_ has quit [Quit: Leaving]
atommann has joined #qi-hardware
<DocScrutinizer05> wpwrak: well, anything significantly larger than the castle bravo or Tsar is simply useles, it just blasts away the vacuum in empty space
<DocScrutinizer05> though I admit the term "useful" is strangely odd for such experiments
<larsc> if you don't succeed at making a dent in the universe you can still try to make a dent in the planet
<wpwrak> btw, the best "short liftoff" is at 11:13. just the right height :)
<DocScrutinizer05> I guess 11:30 is the panorama view of [2014-03-08 14:42:52] <DocScrutinizer05> 11:58 rather
<DocScrutinizer05> roh: thanks a lot for pointer to ina219, we decided for ina231 now
<wpwrak> yeah, they have three different views
<DocScrutinizer05> roh: high-end shunt, nice small package, 0.3mA supply current when active, and hooray, even a ALARM IRQ line with programmable trigger. Range 0.15mA .. 4000mA with a pretty low shunt of 20mR
<DocScrutinizer05> s/trigger/threshold
<qi-bot> DocScrutinizer05 meant: "roh: high-end shunt, nice small package, 0.3mA supply current when active, and hooray, even a ALARM IRQ line with programmable threshold. Range 0.15mA .. 4000mA with a pretty low shunt of 20mR"
