02:17 < muurkha> if you print on a cheap 3d fdm printer you are going to have a lot of creep
02:19 < muurkha> if you have 6DoF closed-loop feedback that doesn't matter but if you lack either one you will be a sad panda
02:20 < muurkha> you also have ugly TCE like 100 ppm/°.  thermosets are a lot better on creep but still have shitty TCE
02:23 < muurkha> again, not a big deal if you have 6DoF closed-loop feedback
02:23 < muurkha> (or however many degrees of freedom you care about; the rotations produced by creep or nonuniform warming can be pretty small)

03:50 < maaku> lsneff: I assume you have read Case for Mars and Case for Space. Have you read Mining the Sky and The High Frontier?
03:51 -!- otoburb_ is now known as otoburb
05:39 < srk> openflexure body is pretty cool
05:39 < srk> hehe 'Before FACT, generating flexure concepts was a matter of experience, creativity, and divine inspiration.' from http://web.mit.edu/mact/www/Blog/Flexures/FlexureIndex.html
05:52 < lsneff> maaku: I don’t think I have
05:59 < muurkha> the guy who came up with FACT has a pretty good series of videos explaining basic kinematics and also FACT
05:59 < muurkha> even if he does wear a suit he isn't clueless
06:12 < muurkha> this Marcel guy seems enthusiastic about his work
06:14 < srk> muurkha: yep, watched the first two introductory videos, looks good
06:14 < muurkha> there's one series that's aimed at the vulgar and another that's university-level
06:32 < muurkha> Marcel Thomas also mentions Howell's pseudo-rigid body model, but I think maybe superior is the approach taken by Megaro, Zehnder, Bächer, Coros, Gross, and Thomaszewski in 02017: https://www.baecher.info/publication/comp_mech_sig17/
06:40 < muurkha> I forget if we mentioned https://www.pnas.org/content/119/1/e2111505119 in here previously but it's a deep-learning based approach to flexure design
06:43 < muurkha> has anyone been able to find Thomas's master's thesis?  he mentions it a lot in this page but the link from his home page goes to http://web.mit.edu/mact/www/Projects/Research/SMThesis/SMThesisIndex.html which is 404 and not in the IA
07:08 < lsneff> If you can’t find it, might be worth finding the their email address and asking them for a copy.
07:17 < muurkha> I think it's https://dspace.mit.edu/handle/1721.1/92061

13:01 < adlai> how did /topic earn "banned by the MIT media lab" ?
13:03 < lsneff> I’ve always wondered that
13:27 < nmz787_> eh, just speculation I think
13:27 < nmz787_> given their general aire
14:26 < maaku> lsneff: add them to your list!
14:28 < maaku> adlai: MIT got pissed that kanzure s/venture capital/vampires/ in a transcript, or something like that
14:28 < maaku> or maybe it wasn't VC's? I forget who was the vampire
14:30 < maaku> getting pissed over a joke in a transcript provided and hosted at no cost at a speed you can't even buy off the shelf... that was pretty low form of them

17:21 < kanzure> "like genghis khan but with more pizzazz"
17:22 < kanzure> .tw https://twitter.com/json_dirs/status/1486120144141123584
17:22 < saxo> More fun publisher surveillance: / Elsevier embeds a hash in the PDF metadata that is *unique for each time a PDF is downloaded*, this is a diff between metadata from two of the same paper. Combined with access timestamps, they can uniquely identify the source of any shared PDFs. https://pbs.twimg.com/media/FJ-6qy4UYAIFbjw.jpg (@json_dirs)
17:30 < L29Ah> kanzure: seems like someone deliberately makes ineffective tracking solutions on behalf of Elsevier
17:31 < L29Ah> i can't explain this stupid stuff otherwise
17:32 < L29Ah> any half-assed infosec specialist or data scientist could think of a better fingerprinting scheme in half a minute

18:34 < lsneff> The talk today went really well
18:35 < lsneff> Got a couple people reaching out to me afterwords
18:35 < lsneff> An engineer at blue origin wants me to give the talk to a small group there
18:36 < kanzure> dew it.
18:39 < lsneff> I will, I did promise myself at one point that I wouldn’t work for blue origin, but we’ll see
18:41 < kanzure> https://vtdigger.org/2022/02/08/vermont-house-approves-prop-5-sending-reproductive-rights-question-to-voters/
18:41 < kanzure> i think this was the pro-embryo modification bill
18:41 < kanzure> https://legislature.vermont.gov/bill/status/2022/PR.5
18:42 < kanzure> "That an individual's right to personal reproductive autonomy is central to the liberty and dignity to determine one's own life course and shall not be denied or infringed unless justified by a compelling State interest achieved by the least restrictive means."
18:42 < lsneff> Also have a meeting on Sunday to talk about a fall internship at e11 bio
18:42 < lsneff> Gotta choose between brain and space at some point I guess
