<p>> When I joined Oxide last year, one of the first things I was introduced to was our racklettes; that is, smaller than average racks of four sleds and two switches each. These racklettes can be initialized and run just like a real rack, precisely because they are a real rack. Just not in any form factor it would be economical to sell.<p>Probably shouldn't have mentioned this publicly ;) Every time an Oxide post comes up, there's people in the comments expressing fervent wishes for just this sort of thing. Now that they know it exists, I imagine the the voices asking to make it available for developers and homelabs will grow even louder.</p>

<p>Anyone interested in this might also enjoy the book <i>The Perfectionists: How Precision Engineers Created The Modern World</i>, by Simon Winchester. I read it a few years ago, and thought it was a really interesting journey through bootstrapping precision and how that fundamentally changed our relationship to certain types of things, particularly related to mass production of "good enough".</p>

<p>I've played around with most of the solutions in this space (OnShape, Fusion360, FreeCAD, Solvespace), but honestly at this point would probably just end up paying for the Solidworks hobbyist license; it's like $4/month and I have a Windows desktop available. That said, there's been some consensus built over the past few years about what the next-gen CAD software should probably look like, ranging from modern scripting capabilities to version control and intermediate shape representations.<p>A big of the attraction of re-building this kind of foundational software isn't the base capability (commercial 3D CAD has barely even seen incremental improvements for more than a decade, in large part because it's just pretty well solved in the existing programs), but that a modern kernel would be a major step forward for unblocking implementation of some of those other capabilities.</p>

<p>I'd love to see something like this for Solidworks, but think you're in for a boatload of trouble there. OpenCASCADE is less capable than Parasolid, and a true Rust-based parametric geometry kernel capable of boolean joins, fillets, etc. needed for anything resembling a modern feature set is wickedly difficult (that's one of the reasons why everyone licenses existing ones and don't try to roll their own).<p>Don't let that discourage you, though! A fast, local, fully-featured 3D parametric CAD program that takes advantage of modern hardware parallelism that can be extended/scripted is just basically one of the holy grails of software and even exploratory efforts might uncover some great paths forward to making that a reality!</p>

<p>I don't disagree with your point, but I did read a post by Sean Goedecke[1] (whose opinions on the world of LLM-stuff I've generally come to respect) that I found relevant. It's not that the second-order effects don't matter to them, it's more that both the cat's probably out of the bag on those negative externalities regardless of the progress of frontier models, and that they are truly, sincerely, in-their-bones worried about the first thing and therefore focused on it since that's something that they might still have some agency over.<p>[1] <a href="https://www.seangoedecke.com/they-really-do-think-ai-might-kill-everyone/" rel="nofollow">https://www.seangoedecke.com/they-really-do-think-ai-might-k...</a></p>

<p>I'm going to be blunt; this is a wildly bad-faith argument. You started the quote right after the important word: illegal.<p>> the illegal, unpermitted gas turbines they've been running at their Memphis Colossus data center<p>Illegal. These turbines are illegal. What xAI under Musk's direction is doing is illegal. A business that must break the law to be practical isn't a business, it's a criminal organization operating by hurting people (which is WHY it's illegal to run gas turbines like this), and both it and those running it must be held accountable.<p>You're arguing that it's fine to break the law if it would otherwise cost a business money. I don't accept that, and nobody else in this community should either.</p>

<p>Years ago, I did some work on thermal management of small satellites, mostly for cooling higher-power onboard computers. The scale is different, but the physics are the same.<p>The story of SpaceX is often that Musk tried to buy a rocket, got a price estimate, and did some first-principles evaluation of the materials and engineering costs he believed was involved that came out to be much less than the going price. He ended up (through fast-forward view doing a lot of work) being largely correct.<p>The data-centers-in-space in space thing does not work out from a first principles approach. The waste heat generated by chips and the cooling method available (ultimately, radiative cooling), and the structures required create those surfaces, would be orders-of-magnitude beyond what could reasonably compete with a terrestrial version with the same capacity. There's no "but launch costs are dropping" adjustment that can possibly make up for that. The physics involved are the blocker.<p>Starlink is actually a good counter-example of where the execution--building and coordinating satellites in volume--was the bottleneck, not the underlying physics of the networking and SpaceX was in a great position to capitalize with their engineering expertise and reduced launch costs. It's a totally different situation for the data center thing, though.</p>

<p>I often like SemiAnalysis' work, but there's parts of this article that are shockingly under-researched and completely missing critical parts of the narrative.<p>> Eighteen months ago, Elon Musk shocked the datacenter industry by building a 100,000-GPU cluster in four months. Multiple innovations enabled this incredible achievement, but the energy strategy was the most impressive.<p>> Again, clever firms like xAI have found remedies. Elon's AI Lab even pioneered a new site selection process - building at the border of two states to maximize the odds of getting a permit early!<p>The energy strategy was to completely and almost certainly illegally bypass permitting and ignore the Clean Air Act, at a tangible cost to the surrounding community by measurably increasing respiratory irritants like NOx in the air around these communities. Characterizing this harm as "clever" is wildly irresponsible, and it's wild that the word "illegal" doesn't appear in the article once, while at the same time handwaving the fact that permitting for local combustion-based generation (for these reasons!) is one of the main factors to pushing out timelines and increasing cost.<p>[1] <a href="https://time.com/7308925/elon-musk-memphis-ai-data-center/" rel="nofollow">https://time.com/7308925/elon-musk-memphis-ai-data-center/</a><p>[2] <a href="https://www.selc.org/news/resistance-against-elon-musks-xai-facility-in-south-memphis-gets-stronger/" rel="nofollow">https://www.selc.org/news/resistance-against-elon-musks-xai-...</a><p>[3] <a href="https://naacp.org/articles/elon-musks-xai-threatened-lawsuit-over-air-pollution-memphis-data-center-filed-behalf" rel="nofollow">https://naacp.org/articles/elon-musks-xai-threatened-lawsuit...</a></p>

<p>I don't love this comparison, because I have to use Linux, not Mac.

<p>Not that it's super relevant to this discussion, but I think the largest individual machines operated would probably have to go to high energy particle accelerators like the LHC at CERN or those operated by Fermi Lab.<p>Billions of dollars in cost, run 24/7 with virtually no downtime during regular operations, in underground tunnels with circumferences in the tens of miles, and all throughout is actively-coordinated super conductors and beam collimation in a high-vacuum tube attached to absurdly complex, ultra-sensitive, massively-scaled instrumentation (not to mention the whole on-site data processing and storage facilities). Certainly open to bring convinced otherwise, but aside from ISS in pure cost, so far it's my understanding that those are the pinnacle of large-scale machines.</p>

<p>I haven't heard anyone mention this rule, which I think is useful:<p>Cars, dogs, and water.<p>These are the big three common things that children interact with regularly that can, and will, cause irreparable harm or death with  functionally no warning and virtually instantaneously. Kids also don't have the experience or the intuition to figure out if a situation is dangerous; cars move too fast, dogs are too hard to read, and water danger is hard to grasp even for adults (the number of  people, including grown adults, I've seen panic and had to get pulled out after gleefully jumping into water where it turns out they can't reliably touch the bottom is fairly high).<p>The first two require some strictness (i.e. being <i>very</i> clear about rules like never going near a road without an adult, and never hitting a dog or pulling it's ears), but water basically requires regular swimming lessons from qualified instructors. It's something I wish happened earlier, and that more families had easy access to.</p>
