<p>Just to make sure I understand: Is the resizable BAR/MMIO a RAM buffer for PCie packets? Or does it have some deeper integration with DMA or something? I assume it's not like memory mapped peripherals on an AXI bus which is why you need the buffer?</p>

<p><i>> They use a high mghz signal to measure the tip temperature using impedance measurements IIRC. Then they control the tip temperature using a feedback control loop.</i><p>That's not how Metcal fixed temp induction soldering irons work. They don't have a control loop, which is what makes them so much better than other soldering irons.<p>They exploit the Curie temperature [1] of some alloys, in which the metal loses its inductive properties when it hits a certain temperature. A Metcal power supply pumps a simple 13.56 Mhz signal into the tip which heats it up and when it reaches its Curie temperature, it just stops heating. Since the signal is constant, whenever the temperature of the tip drops it just heats back up without any PID loop. The downside is that you have to switch tips (alloys) with a pair of pliers to change temperatures, but the upside is that there is no control loop delay.<p>It's also why their station are so reliable. There's basically no "modern" electronics in them and the worst you have to do to fix them is replace an electrolytic capacitor. I've got a power supply manufactured in the late 90s that's still as good as new and like you said, going back to a Hakko or any other soldering iron is downright painful.<p>(Side note to anyone who cares: when the patents expired, a couple of Metcal engineers left to form Thermaltronics, which sells cheaper stations and Metcal-compatible tips)<p>[1] <a href="https://en.wikipedia.org/wiki/Curie_temperature" rel="nofollow">https://en.wikipedia.org/wiki/Curie_temperature</a></p>

<p><i>> Yet, it's all the most likely token and my brain hurts trying to understand how that can be.</i><p>You and everyone else. That's the great mystery of transformer architectures as applied to language.<p>To be clear though, they're only good at <i>schematic capture</i>, which is very much a textual representation. Most of the data basically boils down to netlists, which are a text based format mapping connections between abstract pins that only later map to physical copper. The actual schematic portion is for human consumption and LLMs don't need to produce those to be useful.<p>Where LLMs completely break down is the next step, PCB routing. That's an NP-complete research problem that's been ongoing for decades without much progress. I've had some fun playing with using LLMs to better specify DRC rules in Altium so that the "classical" algorithms are more usable, but at the end of the day their geometric intuition is nonexistent.</p>

<p>I think we're underestimating just how much low hanging fruit there is.

<p>The important part of the professional certification like PE or MD is the liability that comes with it, which means that the professional has a lot more agency. A construction firm or hospital can't really force their professionals to do anything because the consequence is criminal prosecution (and a lot of legal liability for the employer).<p>Bring a software engineer into a courtroom as an expert witness, and the jury's eyes will glaze over. Bring in the PE who told their firm not to cut that corner, and the hammer comes down hard.<p>Even if the certification for software engineers starts as barebones as knowing what WASP is, it still provides an avenue for the feedback mechanism to work (the rules "written in blood"), so that the entire industry can study and learn from what happened, instead of this mess we have now, the peak of which is postmortem blog posts. Even now we have plenty of examples of regulatory frameworks where the regulations adapt to the field like the FDA where you've got a huge spectrum ranging from diagnostics to medical devices of which where are many classes, and drugs where every clinical trial can be tailored to the exact nature of the disease.</p>

<p><i>> They think they can just unload to some sucker for a big payday. See also the entirety of cryptocurrency.</i><p>That's also the entirety of the biotech VC industry, except even more so.<p>Biotech startups require far more capital to make it to market than tech startups, so biotech VCs take the role of early stage funding for R&D. Then the startup IPOs (with zero revenue and unlimited scientific risk) and uses that to fund its clinical trials, while the investors dump their stock. Then, because ramping up manufacturing and quality control takes even <i>more</i> money, the biotech startup sells out to a pharmaceutical company once its passed its trials or the results are promising enough to take the risk, closing the financing loop. Most of these startups stop existing before they even earn a single dollar in revenue, either because they fail or they're acquired by someone who can actually manufacture and distribute their product at scale. This has been the way of the industry for at least the last 20-30 years ever since the small molecule cliff hit like a brick wall.<p>So, the VC industry whose standard operating procedure is to unload companies onto public investors long before anyone even knows whether the drug or device would work, wouldn't touch Theranos with a thirty foot pole.</p>

<p>This is really cool!<p>I'm wondering what data you're using and if you can impose a more precise coordinate system into the visualizations with ways to track a specific point (perhaps starting from polygons or GPS coordinates). It seems the visualization includes sea level rise but it's hard to figure out if its getting other details right like the California’s Transverse Ranges uplift (~20 mYa to present)  which moved the Los Angeles basin several hundred kilometers northwest all while San Diego and Baja California were also rearranged.</p>

<p>It wouldn't have worked, period. You can't use capillary blood for the kind of blood tests they were claiming to. It's statistically impossible because the sample isn't big enough and drawing <i>more</i> capillary blood doesn't improve the SNR. Two samples taken at the same time from different spots on the same finger can yield wildly different results.<p>Everyone in diagnostic medicine knows this (they've been dealing with this problem since the glucose finger prick test). That's why no biotech VC ever invested in Theranos and they had to get tech VCs and fancy board members like Henry Kissinger. A cursory glance at the proposal by someone qualified would have shut that down immediately, but tech VCs don't do due diligence anymore.</p>

<p>That's a well studied topic in military history/science called unit cohesion. The saying goes that morale gets the soldiers to the battlefield, cohesion is what keeps them there. In order to withstand the psychological horrors of combat, soldiers need that comradery otherwise they'll run off at the first chance they get. There needs to be <i>some</i> anchor keeping the soldier in the way of danger, whether that's social pressure or years of intense training together.<p>Brett Devereaux has talked about it multiple times on his blog in various different contexts (most recently two weeks ago)[1][2][3]:<p>[1] <a href="https://acoup.blog/2026/07/24/collections-pre-modern-armies-for-worldbuilders-part-ivb-cohesion/" rel="nofollow">https://acoup.blog/2026/07/24/collections-pre-modern-armies-...</a><p>[2] <a href="https://acoup.blog/2022/07/01/collections-total-generalship-commanding-pre-modern-armies-part-iiic-morale-and-cohesion/" rel="nofollow">https://acoup.blog/2022/07/01/collections-total-generalship-...</a><p>[3] <a href="https://acoup.blog/tag/cohesion/" rel="nofollow">https://acoup.blog/tag/cohesion/</a></p>
