<p>Oh, that helps me.  I thought it had something to do with rotating the palm.  Why did they go into all the detail of the ulna & radius crossing?<p>The counter example they gave was the elephant - but this video [1] of elephants walking looks to me like "bunny hands", at least to a degree.<p>[1] <a href="https://www.youtube.com/watch?v=yf1K63tc1bY" rel="nofollow">https://www.youtube.com/watch?v=yf1K63tc1bY</a></p>

<p>This would make for a good topic on a short-form pop-science YouTube channel.  (take your pick)<p>The article is interesting but it's difficult for me to really picture the implications of the article.  Actually after reading it I get the feeling that what I was visualizing is entirely contrary to what they are trying to convey to me.</p>

<p>It sent me back in time, very nostalgic.  I even took a few minutes to sit and enjoy the moment and remember what it was like to explore the internet on a pixelated CRT in the 90s.<p>I suspect it's a generational gap.</p>

<p>What a fascinating project.  It looks a real labor of love, and I wish I understood it more deeply.  I've been making my own visualization sandboxes like this to explore configuration spaces and groups - but for much simpler, more intuitive physical systems.<p>I went down a few rabbit holes on the site - is this program also written in Basic?</p>

<p>I can't go into detail, but that's essentially my use case.  I have a geodesic dome with a cable running up externally, and would like to run it through a hollow shaft coming in through the top which rotates like a carousel.  I'm fairly certain this is precisely what I need.</p>

<p>What?!<p>Thank you!  I'm working on a robot with a very expensive slip ring, and need to send high fidelity data through it with shielding.  I had no idea this was possible this will make things so much easier!<p>I found a related video you might find interesting.<p><a href="https://www.youtube.com/watch?v=gZvimEf6DFw" rel="nofollow">https://www.youtube.com/watch?v=gZvimEf6DFw</a><p>I'm currently studying group theory and SO3 rotations (quaternions & matrix groups) and I'm also curious about the connection.  I still have a lot to learn but I wouldn't be surprised if the reset rotation is unique, if we abstract away variation.</p>

<p>That sounds frustrating!  It hasn't been my experience at all.<p>I'm an enthusiast when it comes to [Vanilla] Emacs.  I enjoy customizing my editor, jumping into the Lisp when I find an error, and contributing - though my own config is usually the problem.<p>This sounds like an opportunity to improve the day-to-day for developers!<p>Please report any verified bugs to Github.  There are only 12 open issues, most of them enhancement requests.  The maintainers are celebrated in the community for their diligence and attentive engagement, and I'm sure they'd love to help.</p>

<p>I've been using Magit for years, and have never noticed any bugs.<p>The interface is unique and takes a lot of getting used to.  I did need to leverage my extensive experience with Git and Emacs to understand unexpected behaviour but the fault always lay with me.<p>Given the implications of bugs in such a critical part of a developer's workflow, can you be more specific?</p>

<p>Loved the article, and also the shoutout to Strang's lectures.<p>I agree with the order, the Gaussian should come later I almost closed the article - glad I kept scrolling out of curiosity.<p>Also I felt like I had been primed to think about nickles and pennies as variables rather than coefficients due to the color scheme, so when I got to the food section I naturally expected to see the column picture first.<p>When I encountered the carb/protein matrix instead, I perceived it in the form:<p>[A][x], where the x is [milk bread].T<p>so I naturally perceived the matrix as a transformation and saw the food items as variables about to be "passed through" the matrix.<p>But another part of my brain immediately recognized the matrix as a dataset of feature vectors, [[milk].T [bread].T], yearning for y = f(W @ x).<p>I was never able to resolve this tension in my mind...</p>

<p>I love this idea.  I remember giving a live demonstration of a configuration management tool (SaltStack circa 2012) and some unknown networking conflict between my Virtual Machines and the local wifi subnet caused my commands to timeout.  I was too junior to resolve it live and was left with boring slides explaining what <i>ought</i> to be happening.<p>Luckily it was a small group of devs and not a large venue.  Still embarrassing...</p>

<p>I've been curious about knitting & crochet from a programming / robotics / simulation perspective for a while, but deferred it to cut my teeth on simpler problems.  Those industrial robots seems to be knitting, not crocheting.  They use the term "crochet knitting" as a sales tactic.<p>This short video is annoying but informative: [1]<p>The closest I've seen to <i>actual</i> robotic crochet is [2].<p>Which is exciting and close - but it's hard to overstate its limitations.  I took the challenge in that short video seriously and spent 10-20 hours learning basic crochet.  It became very clear that replicating my simple test patterns would require vision, planning and modeling capabilities beyond anything I've seen in SOTA surgical robots.<p>What I find interesting about the post (Knotty) is buried here [3] - apparently it's possible to ditch the grid and create an intuitive representation of the final knit pattern.  I suspect that may be doable using traditional algorithms.<p>[1] <a href="https://www.youtube.com/watch?v=EImnSsCadK8" rel="nofollow">https://www.youtube.com/watch?v=EImnSsCadK8</a><p>[2] <a href="https://www.youtube.com/watch?v=T1-pfeaVsOM" rel="nofollow">https://www.youtube.com/watch?v=T1-pfeaVsOM</a><p>[3] <a href="https://stitch-maps.com/about/overview/" rel="nofollow">https://stitch-maps.com/about/overview/</a></p>

<p>It's a lot to ask of two experts to also be excellent communicators for an audience that may struggle to follow along.<p>I wonder if a potential application of LLMS could be: have two experts have a really interesting but dense conversation with each other, and then translate the conversation into simpler language with interjections for explanations.<p>It may not be enjoyable for the most general audience, but it would scratch an itch for some of us.</p>
