01:06 e_house says no to MrCurious while slipping a siphon tube into his bac
01:17 MrCurious quite a slow boring night
02:17 MrCurious someone sy interesting things before everyone passes out
02:17 e4016 passes
02:18 Faek No
02:19 MrCurious Faek!
02:19 Faek MrCurious!
02:19 MrCurious is your name a corruption on a popular F-word?
02:19 Faek No
02:20 MrCurious Fake?
02:20 Faek It is a mispelling of Fake
02:20 Faek So not a corruption
02:20 Faek Also i can describe the question i'm working on for physics if you wish MrCurious
02:20 MrCurious Well faek me i was wrong
02:20 MrCurious yes please
02:22 Faek A 200N (approx 20kg) board is placed across a 3m stream with 1 bank at right angles and the other at 36.9 degrees to the horizontal. A 400N (approx 40kg) boy attempts to walk across it. If e coefficient of static friction at each side is 0.4 , determine if he can make the crossing and if not how far will he get before the board slips
02:23 MrCurious faek: what country are you in?
02:24 Faek Australia
02:24 MrCurious well that rules out land mines and snipers...
02:24 Faek Does a bit yes
02:24 MrCurious but i am sure a wild fire will likely kill him
02:26 Faek It is heading into summer
02:27 MrCurious hopefully our southern california fire season ends without incident
02:30 theBear i can get you a landmine or sniper rifle in .au if you need one
02:33 SleepersTide theBear: really?
02:37 theBear for legal reasons, i'm gonna say "of course not" :)
02:37 theBear <nudge nudge wink wink>
02:37 MrCurious is a tank within the realm of possibility?
02:37 theBear i dunno, noone ever offered, and i never asked
02:38 theBear someone stole one about 20 years ago, or maybe it was a tank minus big gun, i forget
02:38 theBear not that it disappeared onto the blackmarket, they went on a little rampage and eventually got stopped
02:52 SquirrelCZECH wow
02:59 SleepersTide theBear: I would so get a rifle if it didn't mean I'd get super arrested
02:59 theBear you only get arrested when you get caught with it
02:59 theBear but i don't recommend firearms, much more fun to hurt people with bare hands
02:59 SleepersTide mm
03:00 SleepersTide I do like knives, though
03:00 theBear knives are tricky... things escalate quickly
03:00 SleepersTide they're not good to have in a fight against someone stronger than you
03:01 theBear i was gonna say something along those lines, more like you wanna be GOOD with a knife if the person you trying to hurt has ANY 'fighting' skills
03:01 SleepersTide yeah
03:02 SleepersTide meh, I don't have any reason to kill people, my only motivation for owning a rifle would be for accelerating small hunks of metal very fast
03:02 SleepersTide I should build a rail gun
03:03 theBear why you need fast metal ?
03:03 theBear ooh, i could get you some quick silver if it helps :)
03:04 Faek Mercury?
03:04 theBear maybe :)
03:36 SleepersTide hahah
03:36 SleepersTide I don't need fast metal, it's just fun and interesting
08:20 TheFinal in your opinion, what is the most efficient locomotion system, in a supposed all terrain and office operation environment?
09:32 Skwint There are rumours that Amazon are going to give out free smart phones
09:32 Skwint I'm trying to figure out what stops me getting, say, 200 of them? :p
09:45 Tom_itx your conscience?
09:45 Tom_itx besides, you don't have that many friends to call
09:46 Faek No shame in that though
10:06 rue_bed most efficient locomotion would be to have an airhockey floor, robot would only need a few muffin fans to get around
10:07 rue_bed ooo heium blimp!
10:22 m_itx ties a helium balloon to rue_bed's
11:10 rue_house interesting
11:10 rue_house #define when break;case
11:10 rue_house #define otherwise break;default
11:10 rue_house I cant wait to see how this goes
11:11 DagoRed that is interesting
11:11 DagoRed what what are you working on rue_house?
11:11 rue_house so it making an array of external functions in a structure
11:11 rue_house I'm looking over the source code for dclock
11:12 rue_house while eating breakfast
11:14 rue_house static void
11:14 rue_house quit()
11:14 rue_house {
11:14 rue_house exit(0);
11:14 rue_house }
11:14 rue_house huh
11:15 rue_house I think someone is used to a different language
11:16 rue_house shower and robotics
11:21 DagoRed got it
11:22 DagoRed That looks more like.... someone likes using Java.
11:31 rue_house ah, thats java mechanisms eh?
11:32 rue_house that would expaoin why goes to all that work to create a quit function used only once
11:34 goRed
11:34 DagoRed they're thinking in terms of java methods.
11:35 DagoRed Silly OOP people.
11:35 goRed once upon a time would have done the same th
12:05 DagoRed well... starting a new job on monday
12:05 DagoRed I'll be building robots professionally.
12:21 DagoRed rue_house: question for you. when you make your own shared library (.so), is there a place where one can put their .so so it's in the path at all times without having to edit the LD_LIBRARY_PATH everytime?
12:21 DagoRed For example, shouldn't it be possible to drop a .so into the /usr/lib folder?
13:06 MrCurious new rule. no videos of sarin victims before morning coffee
13:41 DagoRed nevermind, I think I figured it out with rpath at least for right now.
14:23 rue_shop2 DagoRed, I dont make so's I dont do enough programs with cause to utilize that
14:30 DagoRed rue_shop2: Well... these little libraries are handy. I am liking that, but overall I don't see a purpose for them unless this project I am working on increases exponentially in scope.
14:45 rue_house the libraries I have I code right in
14:45 rue_house copile
14:48 MrCurious i need inspiration to get me out of couch potato emulation mode.
14:49 Lola8088
14:50 GuShH MrCurious: you are a couch potato... not much we can do
14:50 GuShH after all this time it turns out you were the poser!
14:51 sw0rdfish lool
14:52 MrCurious the real reason americans are fat http://i.imgur.com/w2aCSGH.png
14:52 MrCurious its also 34C here and the AAC cant keep up
14:53 MrCurious yes the audio codec annot keep up with the heat
14:53 MrCurious AC
14:53 sw0rdfish damnnnn
14:53 sw0rdfish whata hell is that
14:53 rue_house MrCurious, australia?
14:53 sw0rdfish pizza TACO!
14:53 GuShH what the fuck is that thing
14:53 sw0rdfish MrCurious, sir?
14:53 MrCurious san diego
14:53 sw0rdfish lmfao GuShH :D
14:53 GuShH I only have insults toward this type of eating behavior.
14:53 sw0rdfish haha
14:54 GuShH you know what's the worst part? they don't even have real cheese in that piece of rolled up shit.
14:54 MrCurious you know you entertained a simulation of its tste...
14:54 MrCurious taste
14:54 GuShH all processed plastic.
14:54 MrCurious emmm sanitary plastic cheese
14:54 GuShH for instance, margarine is pretty much plastic.
14:55 MrCurious margerine was a bad idea
14:55 GuShH cheddar is mostly flavouring and colouring plus salt, on top of bland cheese
14:55 MrCurious crisco was a good idea. i should note risco vegtable oil solid has on the side, "do not use as a sandwich spread"
14:55 GuShH the actual use was to feed stock
14:56 MrCurious cut out the middle man!
14:56 GuShH not even the animals wanted it, so let's sell it to americans instead. worked out great
14:56 MrCurious i think it was in the eaarly 80's when companies realized they could pay to dispose of food production waste, or they could package it as a "treat" and have people pay them for it
14:57 GuShH but the idea behind it wasn't too bad, to fatten up turkeys and such real fast and cheapily.
14:57 MrCurious we use antibiotics for that
14:57 GuShH it's just that they wouldn't eat it.
14:57 MrCurious and groth hormones
14:57 MrCurious which is why american tits have become HUGE in t\ past 20 years
14:57 GuShH yeah now you do
14:58 GuShH women tits?
14:58 GuShH that's mostly plastic you see.
14:58 MrCurious sadly, it is not a gender specific modification
14:58 GuShH Mom I'm turning 15 soon, can I has tits?
14:58 MrCurious no. tits across the board.
14:58 GuShH That's pot.
14:58 GuShH You guys take everything to the extreme.
14:58 GuShH That's why your grubmint has to tell you what to do.
14:58 MrCurious EXTREME!
14:59 GuShH OVERSIZED JUMBOSIZED BLACKPENISSIZED
14:59 MrCurious are you calling us sheeple, thats baaaaaaad
14:59 GuShH you have less freedom than my balls in winter.
14:59 robotustra http://www.youtube.com/watch?v=C8DmlxM8fQk&feature=endscreen
14:59 MrCurious its not so bad if you dont dwell on it
14:59 MrCurious like food in argentina
15:00 GuShH all you fight for is to parade freely with AR15s on the street for no fucking reason other than you think you look cool doing it
15:00 MrCurious lets have a picture of your next meal gush....
15:00 GuShH you are shielded from reality in fact.
15:00 MrCurious yeah, we love guns designed specifically for killing people, then we get sad when they get used. it is conflicted and confusing
15:00 GuShH constantly being fed with bullshit propaganda that makes you think you're the best of the best
15:00 MrCurious we are somewhat retarded in fact
15:00 GuShH pretty much like nazi germany, but on a way sad scale.
15:01 GuShH I had tenderloin yesterday...
15:01 MrCurious processed freezer food?
15:01 GuShH real meat.
15:01 GuShH we don't buy frozen shit.
15:01 GuShH beef tenderloin in fact costs less than other cuts if you take into account the amount of waste everything else produces and the weight of the bones
15:02 GuShH and it's the best meat.
15:02 GuShH of course if you want to get fat and don't mind the grease dripping off your mouth, try ground beef.
15:02 MrCurious now i want a cheeseburger
15:02 MrCurious tyvm
15:03 GuShH unlike what they show you on TV, the stuff they use on processed ground beef is all the offcuts nobody else wants.
15:03 MrCurious we call it mechanically reclaimed meat MRM
15:03 GuShH and if you're going through the DIY route, why even bother grinding it yourself, do you NEED a patty?
15:04 GuShH why not just head to McD then
15:04 GuShH have a dose of meat you don't even know where it comes from.
15:04 GuShH or if it's even meat at all.
15:04 MrCurious i like food that has been prepared by food-robots
15:04 GuShH MrCurious: you should move to Japan then.
15:05 MrCurious you shitting me... you seen the fucked up crap they eat
15:05 GuShH have some used panties for dessert while you're at it.
15:05 GuShH They eat most of what they steal from our ocean
15:05 MrCurious hey! i found a freaky sea monster.... lets see what it taastes like!
15:05 GuShH I would line up every japanese fisherman in my territory and shoot them in the head without second thought. They're worse than weasels.
15:06 MrCurious endangered whale and dolphin are tasty
15:06 GuShH They steal everything, they steal for food. How fucking sad is that? They're tiny men in a tiny island masturbating to the thought of radioactive godzillas
15:06 GuShH KILL THEM ALL.
15:07 GuShH Remember when Japan used to be China?
15:07 GuShH Making crappy shit so they could eat.
15:07 MrCurious how is your pain level gushh
15:07 MrCurious you may want to discuss anger with your doctor and get on a mood moderator :)
15:07 GuShH And what happened to your industries anyway MrCurious, how come Indians pick up your phones, Mexicans put together your vehicles and Chinese manufacture everything you buy?
15:08 MrCurious i havent got a good answer for that
15:08 GuShH Even stuff that says "made in usa" was made in China now adays
15:08 GuShH But you claim it's better than stuff made in China
15:08 MrCurious i think its because we wanted to focus on making software, but NSA has rendered our software un-purchasable
15:09 GuShH The indians are "making" your software too.
15:09 MrCurious indians? dot or feather?
15:09 GuShH You just pretend you coded it yourself after sending them $10 through paypal
15:11 GuShH MrCurious: depends, could be both if they're homosexual.
15:11 GuShH right?
15:11 GuShH dot and cow fetish type.
15:11 GuShH I'm on a mission to offend the entire world today, how am I doing?
15:12 MrCurious you go back to your room, and you dont come out until you are no longer of the gay...
15:12 GuShH Man if only I knew more about native Australians....
15:12 MrCurious and that thing you do with your hands....very bad.
15:12 GuShH That's why rue has hair problems?
15:13 GuShH https://www.youtube.com/watch?v=HGSVYgcy24Q
15:13 GuShH oh shit the other results are... crap, they really exist, people are insane.
15:14 GuShH damn you all weirdos
15:14 MrCurious rule 34
15:15 MrCurious be REALLY careful what you wish for
15:15 GuShH 34�C you said?
15:15 GuShH 16�C but we're going through a major storm...
15:15 MrCurious cnn REALLY wants this war
15:15 GuShH she's... Saint Rose!
15:15 GuShH not really a Saint, more of a biatch.
15:15 GuShH Bitch Rose.
15:16 GuShH CNN is bad for you.
15:16 GuShH do what robotustra does, go build an alien sex robot.
15:16 MrCurious ok, i will switch to watching faux news
15:16 GuShH NO NO NO
15:17 GuShH why do people buy "Chery" vehicles? the fuck?
15:17 GuShH they're not even cheap (cost wise)
15:17 GuShH you have to have a major build up of farts in your brain to want one.
15:17 GuShH we're talking critical fart mass at 200BAR
15:17 GuShH have you seen the mechanics of those things?
15:18 GuShH think Ford KA meets abandoned bicycle in India.
15:18 GuShH Their offspring, a Chery.
15:18 MrCurious that blue robot is the bomb http://www.expo21xx.com/automation21xx/15433_st3_industrial_research/default.htm
15:29 MrCurious talking about robots really shuts that poser GuShH up...
15:32 GuShH ha
15:32 ShH kicks MrCurious' c
15:32 GuShH watching fools fooling around with injectors on youtube
15:32 GuShH so called trained mechanics...
15:42 MrCurious i think desk cleaning will lead to better productivity
16:18 MrCurious thats a negative. entropy was totally increased
16:20 rue_house well lets take a closer look at your desk
16:20 rue_house I see microholes here you aren't storing data bits in
16:20 MrCurious it exposed my monitor hanging system needs a re-work
16:20 MrCurious but being 35C, its too hot to enter te garage
16:20 rue_house well, better now than after it falls off
16:21 rue_house aaah
16:21 rue_house sleep
16:23 MrCurious summer heat sucks for making stuff
16:24 rue_house I have to go to the landfill and get firewood, but I have to change the oil in my truck
16:24 rue_house maybe if I put a drop out the bottom and a drip of new in the top I can achive both at the same time
16:25 MrCurious or delay the ol change up to 1k miles
16:25 rue_house its ticking, it needs the new oil
16:25 rue_house it has enough oil, dont get me wrong
16:25 rue_house its having plugged hydraulic lifter porblems
16:25 MrCurious never heard ticking as a sound a oil change needed made
16:26 MrCurious that sounds llike more of a problem than an oil change
16:26 rue_house I'm kinda flushing the engine
16:26 rue_house tight oil changes
16:26 MrCurious ah, so drain, refiil, run, drain, refil, done
16:26 rue_house last time I flushed it with about 8L of diesel a few times
16:27 rue_house ticking stopped after a while after that
16:27 MrCurious sounds like your oil is gumming up
16:27 MrCurious like your car has bood clots
16:28 rue_house yup
16:28 rue_house I'v got it down to remove and clean out the lifter rods and hydraulic lifters
16:28 rue_house getting at the hydraulic lifters is an issue tho
16:49 MrCurious monitors sorted
21:19 klander Hi. I'm trying to think up a a mechanism for the 'scales' on a snake-like robot. I'd like for these scales to be electrically controlled, but small. what are my options for converting electric energy into mechanical energy for this?
21:22 Tom_itx bi metal
21:22 Tom_itx look at how a blinker relay or christmas tree blinker is made
21:23 MrCurious pizo?
21:24 Tom_itx shape memory wire
21:25 Tom_itx nitinol
21:25 klander yeah looked into that
21:25 klander but the shape shifting would be too slow
21:26 Tom_itx not very efficient either
21:26 klander yeah
21:26 MrCurious pizzo elements, and use vibrations and constructive interference, or a custom surface that has a 1 way friction property
21:28 klander MrCurious, thanks. looking it up
21:28 MrCurious then agin... i might be a poser who knows nothing
21:29 klander are they only pressure -> electricity or do they run both ways?
21:29 MrCurious both
21:30 MrCurious pizzo speaker element
21:30 MrCurious vibrates a diaphram
21:42 klander interesting
21:48 MrCurious probably some kind of bristle material + pizzo
21:49 robotustra pizza-element
21:56 klander piezo
21:58 MrCurious Pie Zoo
21:59 robotustra pipikaka-element
22:23 ace4016 do scales on a snake move the snake? i didn't think it didi
22:23 ace4016 did*
22:24 MrCurious no. active sites on snales move the snale, but snakes are the wave motion
22:25 ace4016 so why make a fancy solution for snake scales? :P
22:25 MrCurious so i suppose a snake replica is composed of something to send waves down body, and something to change the coefficient of resistance or that segment
22:39 klander because id like the snake to be able to stand up
22:39 klander like a cobra
22:39 klander needs to support its own weight
22:40 ace4016 what do the scales have to do with that?
22:40 klander they need not be scales, just segments
22:40 ace4016 ah
22:40 klander but in a real snake the scales overlap each other
22:40 klander so it can flex
22:40 klander and they also provide friction to move forward
22:41 ace4016 well, what would give you more of a snake like movement, look more snake like, and might be pretty cool is to use pnuematic muscles
22:41 ace4016 :D
22:43 klander very cool :D
22:43 MrCurious i think in a snake, it can extend its scales to make them dig in vis lie flat?
22:47 klander yeah probably
23:10 klander okay this would be super ideal for me: http://biorobotics.ri.cmu.edu/robots/medSnake.html
23:11 klander but im not sure how it works
23:11 klander magnets?
