00:00 < fenn> i dont see how a cylinder is optimal for anything
00:00 < genehacker> I've lived on a boat before, it's hard to sleep when the boat is rocking
00:01 < fenn> boats rock because the ocean moves
00:01 < fenn> therefore, anchoring your boat to the water doesn't sound like a good idea to reduce rocking
00:03 < genehacker> the idea behind the barbell design is that your bouyancy is floating on top of the water where the waves are
00:03 < fenn> i think you mean  is not
00:25 < genehacker> yeah
00:26 < fenn> huh. "Polypropylene pellets can easily be obtained at craft supply stores in 2 lb. or 25 lb. bags ($50). (They are intended for use in creating weighted beanbag dolls.)"
00:26 < fenn> better for tupperware than ldpe

20:08 < fenn> so, looks like there's going to be an igem team at iu this summer
20:08 < kanzure> do the participants seem competent? a good advisor ?
20:09 < fenn> the advisor is really clueful
20:10 < kanzure> I'm considering banning marc.
20:10 < fenn> his name is "ryan lee" and i think he's the head of the new iu "biotech" masters program
20:21 < kanzure> argh, another "one line response" from Marc
20:21 < kanzure> what the hell is up with this guy anyway?

21:19 < fenn> units!
21:19 < fenn> amazing isn't it
21:25 < kanzure3> hey for my spiral generator I should have used the tangent at that point on the spiral to determine the direction of the cross section
21:25 < kanzure3> fenn: who did this and how can I stalk them
21:26 < ybit> yeah, what's w/ the resume posting
21:26 < ybit> must be desperate for ajob
21:26 < kanzure3> ybit: his resume sucked anyway
21:26 < kanzure3> level 3 technical support? what the fuck, I mean, seriously..
21:26 < ybit> :P
21:26 < kanzure3> "information technology specialist"
21:26 < kanzure3> bwahah
21:27 < ybit> he probably wasn't trying to show off, he's probably desperately in need of a job
21:27 < kanzure3> behold! as I answer your technical questions!
21:27 < ybit> hehe, that was me way back when i had the ref librarian job
21:27 < kanzure3> I'm so sorry.
21:28 < kanzure3> my first job was saving the world from evil, kicking ass and taking names never.
21:28 < fenn> agh these stupid email addresses always get me mixed up
21:28 < kanzure3> wha?
21:28 < fenn> openmanufacturing@groups.google.com doesn't work
21:28 < fenn> I demand a reason!
21:28 < kanzure3> @googlegroups.com
21:29 < kanzure3> because Google's a giant vagina.
21:29 < kanzure3> that's why.
21:30 < fenn> a vagina?
21:30 < kanzure3> metaphorically?
21:30 < kanzure3> ok, maybe not.

21:54 < fenn> why would an evil mastermind be seeking employment
22:10 -!- emlyno [n=emlyn@eth13582.sa.adsl.internode.on.net] has joined #hplusroadmap
22:19 < kanzure> fenn: presumably because his evil plan hasn't enough funding yet?
22:19 < kanzure> Hi emlyno.
22:32 < kanzure> fenn, how do you think a domino spiral algorithm would work?
22:33 < genehacker> what do you mean?
22:33 < kanzure> well remember the only thing wrong with my previous spiral generator was that the "dominoes" would be pointed in the wrong way at different parts of the spiral
22:33 < kanzure> of course they weren't dominoes, but it's equivalent.
22:34 < genehacker> oh
22:35 < genehacker> yeah I remember
22:35 < genehacker> did I tell you? I have reprap parts in the print queue
22:35 < kanzure> neat, make me some copies :)
22:36 < genehacker> well I can't really use a reprap in my dorm room because of the fire code...
22:37 < kanzure> my lab will probably store it if you want
22:37 < kanzure> if you want me to check, I mean.
22:37 < fenn> der... domino spiral algorithm?
22:37 < kanzure> or actlab will store it, that too
22:37 < genehacker> I am not talking about storing it, I'm talking about using it
22:37 < kanzure> fenn: to place dominoes in a spiral.
22:38 < fenn> well, presumably you have some domino placing machine
22:38 < kanzure> genehacker: well, IIRC it was the size of a desk, right?
22:38 < genehacker> well I asked actlab about the reprap they had and I got no response
22:38 < genehacker> yeah I think so
22:38 < kanzure> fenn: right right, but I mean, my algorithm originally had them all facing the same direction
22:38 < fenn> so tell that machine to move in a spiral, and poop out dominoes at regular intervals
22:38 < kanzure> so at the edges they'd be all wrong
22:38 < kanzure> blah
22:38 < fenn> you have to rotate them
22:38 < kanzure> I'm making an analogy, screw the domino placement machine (as much as I'd like them)
22:38 < kanzure> rotate it to what though?
22:38 < fenn> the angle around the spiral
22:38 < kanzure> I think it's rotation to the value of the tangent at that point
22:39 < genehacker> yeah
22:39 < fenn> that's one way to calculate it, sure
22:39 < kanzure> I should go try that
22:42 < fenn> genehacker: can you dangle the reprap outside your window?
22:43 < genehacker> no, I can't open the window
22:43 < genehacker> I also can't use it in my dorm because I don't like the smell of molten plastic
22:43 < fenn> boo hoo
22:44 < fenn> i love the smell of styrene in the morning
22:44 < fenn> i used to cast figurines in my dorm room with polystyrene fiberglass resin
22:44 < fenn> everyone thought i was making drugs :\
22:45 < genehacker> cast figurines of what?
22:46 < genehacker> kanzure, solidworks has a .csv format
22:46 < genehacker> http://www.triaxialdesign.com/Tips_tricks/newsletter_3.pdf
22:46 < emlyno> is it possible to buy the parts for a reprap at the moment?
22:47 < genehacker> yeah
22:47 < emlyno> where?
22:47 < genehacker> ponoko
22:47 < kanzure> emlyno: not all of them- you used to be able to do it from rrrf
22:47 < kanzure> but now from ponoko, emachineshops, shapeways, etc.
22:47 < kanzure> ponoko has the files already uploaded, fwiw
22:51 < fenn> warhammer 40k figures, mostly eldar and space marines
22:51 < kanzure> hah.
22:51 < fenn> i always wanted one of these http://www.t-licht.de/tt/falcon.jpg
22:52 < fenn> but i settled for a fleet of these instead http://www.t-licht.de/tt/viper.jpg

22:56 < kanzure> does that newsletter describe anything?
22:56  * kanzure checks
22:56 < kanzure> oh yay
22:56 < kanzure> that's definitely csv
22:57 < kanzure> I'll try that out tomorrow when I get to a machine with solidworks
22:57 < kanzure> if you want to do it in the meantime,
22:57 < kanzure> http://heybryan.org/bioreactor/membraneless_filtration/my.txt
22:58 < kanzure> actually, use this one:
22:58 < kanzure> http://heybryan.org/bioreactor/membraneless_filtration/dataplot.cvs
22:58 < kanzure> except replace all ,, with ,
23:01 < genehacker> ummm, how?
23:01 < kanzure> :%s/\,\,/\,/g
23:02 < genehacker> well solidworks is weird, you see when I make a spiral it doesn't have points on the ends
23:02 < genehacker> but if I offset the spiral, the offset does
23:02 < kanzure> what does that mean?
23:02 < kanzure> the offset of what does what?
23:03 < kanzure> how can there both be an and end and there not be an end if there are no points?
23:05 < genehacker> don't you know about the offset command?
23:05 < kanzure> I might. it's been a while though.
23:05 < kanzure> so no, let's assume I don't and work from there
23:05 < kanzure> (why doesn't solidworks 2008 run on wine yet?)
23:05 < genehacker> haha
23:05 < genehacker> I figured it out
23:05 < genehacker> I just have to offset the offset
23:05 -!- wrldpc [n=ben@173.48.207.37] has joined #hplusroadmap
23:05 < kanzure> I'm still not convinced that one-off models are what we want
23:06 < genehacker> yeah
23:07 < genehacker> how do we make a non one off model?
23:07 < kanzure> generator rawr
23:07 < kanzure> fixing it at the moment.
23:08 < kanzure> this way, there's variable parameters, and it's not just restricted to radius or something, plus we can also eventually try different cross sections
23:09 < kanzure> oh, turns out I already accounted for an angle or rotation with the 'oed' command in brlcad
23:09 < kanzure> but I'll see what the #brlcad folks say about its usage. just a lil' debugging to do.
23:11 < fenn> i believe you want a 'toolchain'
23:11 < kanzure> yep
23:11 < kanzure> supposedly this is also supposed to connect to the CFD stuff
23:11 < kanzure> but one step at a time
23:12 < kanzure> genehacker: are you able to immediately use that cvs file that I gave you?
23:16 < genehacker> no
23:18 < kanzure> so I was sitting at the psychiatrist's office a few weeks ago, since the last one died and I needed a prescription for more medication (not really, I buy for impending nuclear winters, but still),
23:18 < kanzure> and on the form it asked "any medical concerns?"
23:18 < kanzure> "any medical concerns: MIGHT BE A ROBOT"
23:18 < kanzure> the doc said, "yeah, we get that a lot."
23:19 < genehacker> impending nuclear winters?
23:19 < kanzure> 3 month supplies.
23:19 < kanzure> Not quite enough :)
23:20 < genehacker> heh
23:20 < genehacker> they get that a lot?
23:20 < kanzure> only aspie psychiatrist practice in Austin apparently
