| kanzure | geodesic distance from curvature extrema based on growing regions associated to local Gaussian curvatures on seed vertices | 00:09 |
|---|---|---|
| kanzure | http://en.wikipedia.org/wiki/Gaussian_curvature | 00:09 |
| kanzure | an integral is the limit of the sum, is it really valid for them to call an integral a sum? | 00:14 |
| kanzure | it's something like: find the curvature extrema of a shape; then for each of those points, take the sum of the geodesic distances to those points. Regular intervals made up of those sums (for each of the points) are then defined as a 'region' and any touching 'region' becomes a node in the Reeb graph. | 00:19 |
| kanzure | I guess there's some threshold value that they're using for considering the mu function to be similar or something | 00:24 |
| kanzure | and then those are the 'region intervals' | 00:24 |
| kanzure | (the mu function is the sum of the geodesic distances at each of the selected points (local extrema)) | 00:24 |
| ybit | for the record: "being back" for me is following along with the community, i'm going to have time to contribute eventually, but when and how much i don't know. i can give you a better estimation of what and how much when this this calendar is created. | 01:00 |
| kanzure | this calendar thingy, is it real? | 01:19 |
| ybit | yup | 01:37 |

| fenn | i think i want to make one of these http://www.lockheedmartin.com/news/press_releases/2009/MFC_022609_LockheedMartinUnveilsExoskeleton.html | 10:23 |
| fenn | with spring stilts though, so i can run 30 mph | 10:24 |
| -!- cis-action is now known as has100ideas | 10:25 | |
| fenn | anyone have numbers on power usage for various exoskeleton usage scenarios? | 10:28 |
| kanzure | no :( | 10:29 |
| kanzure | wasn't there a book that analyzed how much energy Superman and Goku would have to have in order to do the various things that they do? | 10:29 |
| kanzure | such as blowing up planets and crashing through mountains? | 10:29 |
| fenn | eh.. | 10:30 |
| fenn | i just want to throw some cop cars around.. not blow up mountains | 10:31 |
| -!- has100ideas is now known as cowell | 10:33 | |
| kanzure | http://ask.slashdot.org/article.pl?sid=09/04/04/1338228 <- I think this is a bad sign | 10:34 |
| kanzure | there's so many people posting saying "You have no choice" | 10:34 |
| fenn | To help its engineers better understand the challenges that the elderly have behind the wheel (and feed the fears of Japan's midlife crisis population), Nissan has developed an "old suit" simulating stiff movements, blurred vision, bad balance and extra weight (probably to simulate weaker strength). | 10:34 |
| kanzure | opposite direction | 10:35 |
| fenn | "JUST publish it" | 10:35 |
| cowell | I think you really just want a couple of these (http://digg.com/d1m5SJ) instead of a suit | 10:36 |
| fenn | huh. http://en.wikipedia.org/wiki/Statutory_invention_registration | 10:37 |
| kanzure | is that like statutory rape? | 10:37 |
| fenn | basically | 10:37 |
| fenn | all the pain of applying for a patent without actually getting a patent | 10:37 |
| kanzure | "dear mr. president, .." | 10:38 |
| kanzure | basically the only way for this to get done is for something to get passed in the government I think | 10:38 |
| fenn | grrr flash video | 10:38 |
| kanzure | fight it with fire. | 10:38 |
| fenn | i wish i had a command line flash extractor | 10:38 |
| kanzure | (the flash video, I mean) | 10:38 |
| fenn | right now i have to use firefox to do it | 10:38 |
| kanzure | oh, there was something I saw on slashdot the other day | 10:39 |
| kanzure | it was a full javascript+HTML unit testing engine thingy for web scraping | 10:39 |
| kanzure | if you combine that with wireshark and a flash plugin, then you should be good to go | 10:39 |
| kanzure | why are we talking about DNA extraction on diybio again? What's wrong with the protocols that we talked about before? | 10:39 |
| cowell | probably because it is the first thing everyone always things about and we got new members? | 10:43 |
| fenn | time to write a faq | 10:43 |
| kanzure | why haven't you assembled a FAQ yet? | 10:43 |
| kanzure | seriously though | 10:43 |
| kanzure | please don't make me do it. | 10:43 |
| kanzure | I'll be all cranky for the rest of the day | 10:43 |
| cowell | why haven't *you* assembled a faq? ha ha | 10:43 |
| fenn | and it'll just be a huge pile of irrelevant links | 10:43 |
| cowell | ok | 10:43 |
| cowell | ha ha ha | 10:43 |
| kanzure | aw | 10:43 |
| kanzure | come on | 10:43 |
| cowell | ok I'll start a faq. Jason Morrison and I actually started rebuilding the website and we've got FAQ on our list | 10:44 |
| kanzure | http://htmlunit.sourceforge.net/ | 10:45 |
| kanzure | also, can I say 'I told you so' about the multiple mailing lists deal? | 10:45 |
| kanzure | diybio-nyc, diybio-sf, diybio-chicago, diybio-london, and nobody knows to post to the other lists or what's going on at the other places, when it's better if they did | 10:45 |
| fenn | ah the old "to crosspost or not to crosspost" argument | 10:46 |
| kanzure | cowell: I think a good start to the FAQ would just be to go through the archives and categorize posts into different threads | 10:47 |
| kanzure | http://heybryan.org/om.html | 10:47 |
| kanzure | that's what I did for the openmanufacturing list | 10:47 |
| kanzure | it's not quite a FAQ | 10:47 |
| cowell | no, I'm not sure an I-told-you-so is a good idea | 10:47 |
| cowell | I agree with you | 10:47 |
| cowell | Bobe does not - he actually wanted to scold you for cross posting | 10:48 |
| cowell | so I don't know what is better | 10:48 |
| cowell | let's not have a holy war about it | 10:48 |
| kanzure | you're about to get yourself a holy war with the forum idea too :p | 10:48 |
| kanzure | but one step at a time I guess | 10:48 |
| cowell | so do you have a similar list of links at heybryan.org/diybio.html? | 10:49 |
| fenn | forums are evil | 10:49 |
| cowell | ok | 10:49 |
| kanzure | cowell: no :( | 10:49 |
| cowell | well, here's the goal | 10:49 |
| cowell | with the forum | 10:49 |
| fenn | allow people to use animated avatars and smiley icons? | 10:49 |
| kanzure | cowell: IT'S ON MY TODO LIST | 10:49 |
| cowell | basically, there are about 1000 undergraduate igem students actually building biological systems for iGEM right now | 10:49 |
| kanzure | oh, sorry, caps | 10:49 |
| kanzure | didn't mean to yell that | 10:49 |
| fenn | wtf does iGEM have to do with diybio | 10:49 |
| fenn | srsly | 10:50 |
| fenn | they have an entire lab just offered to them | 10:50 |
| fenn | with access to professional staff | 10:50 |
| fenn | that's not DIY | 10:50 |
| cowell | lots of things. but in particular, they practically have a lot of the same technical problems anyone starting with bio101 and trying to do bioengineering has. So they get help from their local experts, and that's it. | 10:51 |
| cowell | The idea is that we also have the same problems, and we could tap into their expertise by helping bridging the two communities to share technical help and tips | 10:51 |
| cowell | and iGEM HQ isn't going to start them a mailing list or forum. | 10:51 |
| kanzure | but there already is an igem mailing list | 10:52 |
| kanzure | what are you talking about? | 10:52 |
| cowell | oh really | 10:52 |
| kanzure | igem-interest is a completely legit list | 10:52 |
| cowell | does anyone ever ask questions on it? | 10:52 |
| kanzure | no, nobody uses email | 10:52 |
| fenn | so let's make a forum for them! :( | 10:52 |
| kanzure | gah | 10:52 |
| kanzure | fenn: so basically the way that I've approached this | 10:52 |
| cowell | stop being so negative | 10:52 |
| kanzure | is that I've scolded them for wanting to use forums | 10:52 |
| kanzure | but | 10:52 |
| kanzure | if they implement a mail2forum gateway, I will not be as negative | 10:53 |
| fenn | cowell: i can't help it, i'm trapped on this planet | 10:53 |
| cowell | ok | 10:53 |
| kanzure | if they won't use a mailing list, why would they use a forum? | 10:53 |
| kanzure | http://heybryan.org/forums.html | 10:53 |
| kanzure | http://heybryan.org/mailing_lists.html | 10:53 |
| cowell | I'm leaving and going to the diybio room. thanks for the talk. bryan, if you want to constructively help me figure out how to engage the large igem biohacking community to help us do diybio sb work, come on over | 10:53 |
| -!- cowell [n=cis-acti@dhcp-0000018522-23-6e.client.student.harvard.edu] has left #hplusroadmap [] | 10:54 | |
| kanzure | wow | 10:54 |
| * fenn shrugs | 10:54 | |
| kanzure | I don't think engaging the igem people is the way to go though | 10:54 |
| kanzure | I mean, there are alternatives that are more related to diybio | 10:54 |
| fenn | i think these boston people dont understand what the rest of the country is like | 10:56 |
| kanzure | time warp bubble manifold around boston dealy? | 10:56 |
| fenn | there's just so much wealth spilling out the seams there it's a different world | 10:56 |
| kanzure | heh | 10:57 |
| kanzure | "wealth" | 10:57 |
| fenn | technical know-how and access to tools and materials | 10:57 |
| fenn | and money | 10:57 |
| kanzure | right | 10:57 |
| fenn | but there's money lots of places | 10:57 |
| kanzure | I'm still trying to transition to university life | 10:57 |
| kanzure | "oh, we just spent a thousand dollars on a bullshit filter design? no big deal, btw do you want a job? ok, great!" | 10:58 |
| fenn | dont get too comfy :) | 10:58 |
| kanzure | actually I'm getting to stay another year | 10:58 |
| kanzure | these two semesters "never happened" | 10:58 |
| fenn | what does that mean exactly? | 10:58 |
| kanzure | my record is reset to zero | 10:58 |
| fenn | how did you manage that? | 10:59 |
| kanzure | dad died | 10:59 |
| fenn | ooo sneaky | 10:59 |
| kanzure | mischevious of me, eh? | 10:59 |
| kanzure | also, the psychiatrist (pre-scheduled visit yesterday) was able to convince mom not to put me into the home | 10:59 |
| fenn | dont waste another $1e4 +- 50% | 11:00 |
| kanzure | he has patients that go to that program and he thinks I'm too functional to get anything of value out of it | 11:00 |
| kanzure | right | 11:00 |
| kanzure | I'm pretty sure I'm going to be able to take a ridiculously small course load | 11:00 |
| kanzure | maybe something like 2 classes? | 11:00 |
| kanzure | and with the income from the two labs, things might be good | 11:00 |
| * kanzure goes down to eat | 11:01 | |
| fenn | netlist import for stripboard cad http://jukumagic.googlecode.com/svn/wiki/screenshot-r36.png | 11:02 |
| fenn | stick that in your graph minimization algorithm | 11:03 |
| kanzure | my what minimization? | 11:04 |
| kanzure | doesn't geda do netlists? | 11:04 |
| fenn | geda doesn't do stripboard | 11:05 |
| fenn | all electronics cad software does netlists (unless it really really sucks) | 11:05 |
| fenn | not sure what sort of netlist this is importing | 11:05 |
| fenn | probably gEDA though, knowing the dev | 11:05 |

| fenn | looks like berkeley exoskeleton averages 250W | 11:16 |
| kanzure | cowell: what were you laughing about? just wondering | 11:16 |
| fenn | that's only ... 70 lithium batteries :\ | 11:16 |
| cowell | that I left in a huff and then came back. I am kind of grouchy today | 11:17 |
| kanzure | fenn: did you see the virus-assembly-electrodes papers I added? | 11:17 |
| fenn | $300 bucks worth.. not as bad as i thought | 11:17 |
| kanzure | cowell: happens to the rest of us. | 11:17 |
| fenn | no, i've read about that before though. angela belcher right? | 11:17 |

| kanzure | yes | 11:18 |
| fenn | cowell: my 10-minute impression of igem is that they almost never finish anything | 11:19 |
| fenn | so good luck getting them to actually document anything, if they can't even finish the project in time | 11:20 |
| kanzure | that's what jonathan cline argues, fenn | 11:20 |
| kanzure | he's here in austin, we should meet up with him sometime | 11:20 |
| fenn | what's he doing in austin? | 11:20 |
| kanzure | he moved here | 11:20 |
| fenn | oh. why? | 11:20 |
| cowell | fenn: ok. it sounds like you're trying to convince me not to deal with igem. | 11:20 |
| kanzure | I think it might be okay to deal with igem, I don't see too much harm coming from being friendly | 11:21 |
| kanzure | however | 11:21 |
| fenn | cowell: i just think they're the wrong place to invest a lot of effort, when you should be focusing on the needs of "real" diy-bio people | 11:21 |
| kanzure | isn't there other things to be doing? | 11:21 |
| fenn | where you = diybio people | 11:22 |
| cowell | fenn: how many "real" diy people are there? 10? 700? | 11:22 |
| fenn | i have no idea | 11:22 |
| fenn | at least 20 looking at the mailing list | 11:22 |
| cowell | I would estimate 20-ish as well | 11:22 |
| fenn | so by the 80/20 rule that means you have 100 "active" members :) | 11:23 |
| fenn | and that aint bad | 11:23 |
| fenn | kanzure: somehow i doubt gold nanowires are going to be cost effective | 11:24 |
| kanzure | how much gold is in the ambient environment? in such a way that cells could find it, and then offload it to viruses | 11:25 |
| cowell | fenn: cool igem projects from last year | 11:25 |
| cowell | 1. http://2008.igem.org/Team:BCCS-Bristol/Modeling | 11:26 |
| fenn | kanzure: ambient environment? there's a sizable concentration in seawater, it's not falling out of the sky though | 11:26 |

| fenn | pretty computer | 11:28 |
| fenn | too bad they are running matlab and java on it.. | 11:29 |
| fenn | this doesn't seems like a supercomputer-class problem to me | 11:30 |
| -!- davidnunez [n=davidnun@140.247.241.205] has joined #hplusroadmap | 11:31 | |
| cowell | well, you could have told them that using the igem-discuss list. Oh wait, it's moderated, so no you couldn't | 11:32 |
| fenn | moderated or closed to outsiders? | 11:33 |
| fenn | their simulations look more like gas dynamics than blobs of goo | 11:33 |
| fenn | was expecting something like myxobacteria | 11:33 |
| kanzure | cowell: it's simply that there are some people who do not know how to communicate using computers | 11:34 |
| kanzure | or don't understand the importance of it | 11:34 |
| fenn | ok, vaccines; can DIYers actually do this? won't we get arrested for "practicing medicine without a license"? | 11:34 |
| fenn | biofabricator subtilis makes what? or is it just a general platform for making other stuff? | 11:37 |
| fenn | seems kind of strange to build a factory without a general idea of what sort of product you'll be making | 11:38 |
| splicer_ | There is probably a division of labor... some build the organism and others test it in the target. | 11:39 |
| fenn | Chloramphenicol Acetyltransferase (antibiotic resistance enzyme) was their "biomaterial"? | 11:40 |
| kanzure | cowell: another idea for the FAQ would be to post and ask people for which threads they found the most helpful in the past | 11:41 |
| fenn | registration required to the-scientist.com | 11:41 |
| fenn | ah the lactobacillus thing is cool | 11:42 |
| fenn | i had the same idea like 10 years ago | 11:42 |
| fenn | then school beat the interest in genetic engineering out of me | 11:43 |
| fenn | another idea in similar vein is an anti-stinky-fart culture | 11:43 |
| fenn | selectively favor anaerobic bacteria that don't produce H2S | 11:44 |
| fenn | so, now i'm wondering why i read all that | 11:45 |
| kanzure | cowell was trying to convince you that igem was so cool that it made it diybio | 11:46 |
| fenn | igem is a great idea and i wish it were around when i was in school | 11:47 |
| fenn | but it's like comparing computer science projects to open source development | 11:47 |
| fenn | except.. less so | 11:48 |
| fenn | because even the poorest programmer has a (theoretically equivalent) computer | 11:48 |
| cowell | ok | 11:50 |
| fenn | anti-pimple culture (kill staph aureus) | 11:50 |
| fenn | well, not kill it, but out-compete it with non-pathogenic varieties | 11:50 |
| cowell | I hold a different perspective than you, fenn. I like igem. I think igem projects are an existence proof of the viability of small teams of relative newcomers with a "small" amount of capital and access to some kind of mentorship repeatably accomplishing interesting results with synthetic biology. | 11:52 |
| fenn | they still have the institutional public image though | 11:53 |
| cowell | who cares! | 11:54 |
| fenn | "students from <prestigious university> did such n such cool thing" is totally different from "students from <underfunded high school> did cool thing" | 11:54 |
| fenn | regardless how much money they actually have | 11:54 |
| cowell | public image is a means to an end | 11:54 |
| fenn | most of the stuff that comes out of MIT is totally doable by the amateur basement hacker | 11:55 |
| cowell | yay! we agree. | 11:55 |
| cowell | and by MIT, do you mean iGEM? or actually all of MIT? | 11:56 |
| fenn | but the way it's framed, and the lack of funding sources and infrastructure for amateur research make it much more difficult | 11:56 |
| fenn | well, mostly i was thinking of the media lab | 11:56 |
| fenn | i realize it's a huge place | 11:57 |
| fenn | i'd like to see some sort of community science labs, open to people without credentials for a small fee | 11:57 |
| cowell | [working on it] | 11:58 |
| kanzure | I thought we were already working on that? | 11:58 |
| * fenn grumbles | 11:58 | |
| kanzure | cowell: could you send me an email to bug me to write the diybio.html page or diybio FAQ? if you send me an email, I'll get around to it later today maybe, or something | 11:58 |
| cowell | seattle open labs, noisebridge/langton labs in SF, whatever we can build here in boston | 11:58 |
| kanzure | I'm about to go apartment hunting | 11:58 |
| cowell | ok | 11:58 |
| cowell | good luke, kanzure | 11:58 |
| cowell | err | 11:58 |
| kanzure | skywalker? | 11:58 |
| fenn | there's only so many different directions i can gallop at once; personally i won't be collecting any bio equipment any time soon | 11:58 |
| cowell | luck* | 11:58 |
| kanzure | fenn: cline wants to though, so I mentioned that I know of a good place to put the equipment if he wants. | 11:59 |
| fenn | ah, cline would be welcome | 11:59 |
| kanzure | you really need to meet up with him. | 11:59 |
| kanzure | just because. | 11:59 |
| fenn | i wasn't really impressed by his student projects :x | 11:59 |
| kanzure | hm? his what? where? | 11:59 |
| fenn | um, on the internet somewhere | 11:59 |
| cowell | 88proof? | 12:00 |
| kanzure | cowell: so anyway, did you recently see the physicaldesignco company? | 12:00 |
| fenn | anyway i doubt my student projects were very impressive either | 12:00 |
| kanzure | basically what they are is a group out of MIT from the Digital Design Lab (or something) in the architecture department | 12:00 |
| kanzure | Physical Design Co. allows users to upload drawings of buildings | 12:00 |

| cowell | cool | 12:01 |
| kanzure | ack | 12:01 |
| kanzure | need to go, but please do check out my post to OM about it | 12:01 |
| kanzure | automatic instruction generation and such, kind of important for diybio | 12:01 |
| fenn | physical design co is basically a shape grammar interfaced to a cnc plywood router | 12:01 |
| kanzure | right right | 12:01 |
| fenn | their grammar could be useful for a lot of other things besides houses | 12:01 |
| fenn | like, that lasercut acrylic stuff, for example | 12:01 |
| cowell | hey fenn, who are you anyway? | 12:02 |
| fenn | some mad scientist | 12:02 |
| fenn | ben lipkowitz | 12:02 |
| cowell | kiko gels? | 12:02 |
| kanzure | oh, I have two more minutes | 12:02 |
| fenn | yeah i posted in that thread | 12:02 |
| cowell | fablab austin? | 12:03 |
| fenn | i think everyone missed the point of what i was saying though | 12:03 |
| fenn | "fablab" or something like it | 12:03 |
| cowell | great | 12:03 |
| kanzure | it's not quite the same thing though. | 12:04 |
| cowell | I met one of the guys who flies around and helps boot-up fablabs recently, and he and I were thinking about approaching the fablab group formally about establishing some kind of basic biotech module for fablabs | 12:04 |
| fenn | last night we were discussing market segments for sex robots | 12:04 |
| kanzure | cowell: Todd? | 12:04 |
| fenn | the MIT fablab (i say MIT to distinguish it from a generic hacker space) approach is to throw a bunch of money at something and hope it works | 12:05 |
| * kanzure turns the key | 12:05 | |
| fenn | instead of letting things grow organically | 12:05 |
| kanzure | a good cite on that would be eric's post | 12:05 |
| fenn | now, i'm not sure which is better :\ | 12:05 |
| kanzure | http://groups.google.com/group/openmanufacturing/msg/2fccdde02f402a5b | 12:05 |
| kanzure | http://groups.google.com/group/openmanufacturing/msg/f456aebde5952d03? | 12:05 |
| kanzure | http://groups.google.com/group/openmanufacturing/msg/2279e9a23f644639 | 12:05 |
| kanzure | http://groups.google.com/group/openmanufacturing/msg/d488e3b75671da7f | 12:05 |
| fenn | but if you don't have people throwing money at you, there's not much choice | 12:05 |
| cowell | kanzure: no, it was an amateur biohacker working at microsoft redmond named mez. (twitter: @ramez) | 12:06 |
| fenn | so when i talk about a fablab on every block, i'm not considering the MIT approach as feasible | 12:06 |
| kanzure | ok, I think fenn can handle this for now | 12:06 |
| fenn | cowell: if you are at all interested in openmanufacturing, at least read all the posts by eric hunting | 12:07 |
| cowell | I think community is important. 1:1 person-fabricator is a fine long-term goal, but there are strong economical and pedagogical reasons for building semi-sentralized fablabs, right? | 12:07 |
| cowell | I read one by erc. | 12:07 |
| fenn | pedagogical, no | 12:07 |
| fenn | that's just academia not "getting it" | 12:08 |
| cowell | I disagree | 12:08 |
| cowell | there is an educational compenent - you have to teach users how to use the equipment | 12:08 |
| fenn | mass production is going to always benefit from centralization; simple geometry | 12:08 |
| fenn | of course you have to teach users to use it | 12:08 |
| cowell | small communities formed around common workshops seems like a great way to do that | 12:09 |
| fenn | but you might have missed the fact that we're living in the future.. we can stream video on demand, auto-generate 3d VR animations | 12:09 |
| cowell | instead of a basement lab for everyone | 12:09 |
| fenn | and we're talking in real time several thousand miles apart | 12:09 |
| fenn | well, 1.5k | 12:09 |
| cowell | it's not technological, it's societal | 12:09 |
| fenn | i didn't say basement, btw | 12:09 |
| fenn | fablab on every block was meant to imply a community space | 12:10 |
| cowell | oh | 12:10 |
| cowell | ok | 12:10 |
| cowell | I think that is a great plan | 12:10 |
| fenn | eric always talks about how you have to design for urban environments if you want something to be scalable | 12:11 |
| fenn | so expecting everyone to have a fully equipped machine shop in their apartment is not scalable | 12:11 |
| fenn | even though there are people with private machine shops | 12:11 |
| fenn | i'm dismayed by how few people are even thinking about automation | 12:12 |
| fenn | when you can buy an automated printing robot for $30, manual pipetting is a crime | 12:13 |
| fenn | benefits from automation extend to so many different areas it's impossible to even think of it all at once | 12:14 |
| cowell | I agree! | 12:15 |
| fenn | are there any standard formats for pipetting procedures? | 12:15 |
| fenn | i remember seeing some files on oww but couldnt download them or something | 12:15 |
| fenn | more important is that the format is open and extensible | 12:15 |
| fenn | kanzure: the amp*hour numbers on those nanowire papers are insane, if the electrode is a significant portion of battery mass | 12:21 |
| fenn | the gold/cobalt ones | 12:23 |

| cowell | hey, I'm giving a talk on diybio right now with kay aull and jason morrison for xorcon.org | 13:16 |

| fenn | huh. "Several chemical research companies are experimenting with diamond-coating fine wires. Tests have shown that the resulting diamond coating approaches the strength of perfect diamond whiskers. All we have to do is set up a process to make these diamond-coated wires in continuous lengths, with the metal substrate etched out, and we have Beanstalk material." | 13:55 |

| kanzure | so I was up until 3 am finishing some work for Campbell, it's not particularly interesting work, but if anyone is interested in glancing over it, check out this: http://sata.serveftp.org/~bryan/3000CFGs_complete.zip | 17:59 |
| kanzure | basically it's the thousand-by-thousand matrix of distances between different designs, where a distance is defined as the euclidean norm of a 'component matrix' (actually, what's called a 'dsm' where array[i][j] represents the number of connections between components of type [i] and of type [j]) | 18:00 |
| kanzure | and then some extra stuff like sorting for the top 50 "most different designs" | 18:00 |

| kanzure | hm, there seem to be a few trajectory planners in the literature | 21:24 |
| kanzure | not what I'm looking for. you need to answer "what to target" | 21:24 |
| kanzure | oh, one method might be to analyze interfences between two parts and find the least-volume combination of the two parts with zero interferences. | 21:27 |
