<p>That's just how perception works. It's rarely fair. People who keep their car running perfectly fine for 20 years will appear like they don't care, people who return a young but worn out near-wreck every time the lease runs out will give the opposite impression. And don't get me started about fast fashion!<p>But it's more than that with residential solar: at least in places where with a heavy oversupply in real estate, "massive capital investment" is hardly a matching term. More like a drop in the ocean, given the amount of capital bound in the whole package.</p>

<p>Fukushima hit hard in (West) Germany: Chernobyl was mostly explained away with "because Soviet", it wasn't that hard to convince people that much safer nuclear was possible. But Japan, of all countries, not being able to safely run a reactor? The country of trains running on time and of Toyotas making domestic cars look laughably unreliable in ADAC statistics?</p>

<p>We don't know what to what fraction that peace movement ran on being propped up by KGB. Those things are not mutually exclusive, genuine protest and getting propped up by a foreign power just for destabilization and giggles.<p>Just like that Red Army Faction group whose name in hindsight was much closer to the truth than anyone really assumed at the time. At least at some point it clearly was a KGB operation (visits to a certain Dresden office are documented, and yes, guess who was also stationed in Dresden at the time), likely not from the start but quickly co-opted. KGB, as in the service that was built on the experience of how Germany solved their eastern front in WWI through organizing passage from Zurich for a certain dissident.<p>Yes, those movements were genuine. But they were also directed to some extent. The fictional Tischbier character in Deutschland 83 comes somewhat close to illustrating that ambiguity.</p>

<p>When the iron curtain fell, there were big plans and a formal contract about modernizing the rail link between Prague and Nuremberg (a hugely important connection on the days of Charles IV). The Czech side eventually stopped electrifying their parts when they realized nothing happened on the other side of the border. These days, Deutsche Bahn is operating a _bus connection_ between the cities. It seems like they are solely focused on beating imaginary Autobahn times between a selected set of major German cities, and consider everything else a nuisance...</p>

<p>Can anyone from the region comment on the status of plans for the landside linkup on the German side? Last time it made the press it was because the project was at risk of seeing the Danish tunnel finished before Germany could tell not even when but if a linkup would ever make it across bureaucratic hurdles. Almost like a Darien Gap made exclusively of red tape.</p>

<p>Sealing is really not that difficult if you have access to the high pressure side. The hard part is identifying the location of the leak. In sum, this means that they have to absolutely nail it, on the first attempt, for the bottom part that is resting on the sea floor. If they can to that, the rest of the circumference will also be so good they don't have to even think about fixability.</p>

<p>Some form of "increment authority" that simply appends to a list of hashes whenever it encounters a commit not yet on the list? Then you could use URI like $authorityhost/orderedcommits/$number as synonyms for the hashes. Multiple increment authorities would not necessarily have them in the exact same order (and "current latest" would likely differ by an order of magnitude or two after some time if you ever had multiple authorities), but it would still provide a lot of intuitive understanding.<p>I wonder how the tag mechanism would perform if you just burned it with this content. I suspect that it would not perform well...</p>

<p>Would the world be inherently different if hardware cost was 4x of what it is per unit of training done? The world would be inherently different if we did not burn through fossil stockpiles at the speed we do, or not at all. It's market mechanisms failing to lead to a desirable outcome. Nothing new about that, plenty of problems of that kind have been solved before, but yes, this one is more difficult.</p>

<p>And the sad part is that ai would be a perfect fit for intermittent energy sources: run inference 24/7 (on whatever you can muster, even if it's fossil it simply does not consume all that much compared to training) and over-build training to achieve whatever total throughout you need in time of energy abundance. How heavy would CO2 pricing have to be to make the market do this instead of the exact opposite?</p>

<p>The trade-off between having the field-swappability feature and going the lean way (it's not just cheaper, also smaller, lighter, less to go wrong) shifts though: when regulation forces companies to go 20% of the way towards field swappability, more will take the bet that there might be a niche worth serving at the 100% mark.<p>I still would not expect this to happen for mainstream phones, but other devices? There will more field swappability with the regulation that enforces layman replaceability then without.</p>

<p>Is it just quantization or is it also rearranging the weights to get clusters with (almost) the same factors? If it's the latter it would very much be training in full precision (but also hardly any precision lost by the compression).<p>Unfortunately my mental model doesn't contain anything to even guess if that's possible or not, my AI times were at the falling flank of symbolic. Funny how one bit models feel a bit like approaching an approximation of symbolic again (until you read about the grouped scale factors and then the illusion is gone)<p>One thought that suggests rearranging is not involved,a thought that does not require any knowledge at all: if it did involve rearranging, someone would certainly have added some order by scale factor tricks with linear interpolation by address offset to lose even less precision.</p>

<p>Status LED and button placement, those would be the the major benefits over conventional boards in non-exotic fields like putting circuits on plants. Would be fantastically valuable for the one-off tinkerer. But yeah, substituting home etching or milling and reflow would also be quite a dream come true.</p>

<p>I guess they consider that a solved problem: when you can drop arbitrary connections without meaningful heating of stuff outside of the connection, just glue your SMD parts wherever you consider convenient and fuse lines to its connection pads.<p>But practical application would likely stick to more or less conventional boards (tiny ones for sure) and use those ink lines only for where it's needed. Unless perhaps there's an application where crossing over with simple fused layer printing allows something revolutionary from going 3D? But 2D boards are really, really cheap and multiple layers are already giving ever conceivable advantage 3D could give, outside of stuff like antenna geometries.<p>For one-off and prototyping, an integrated fused layer + pick&place + circuit fuser machine could be super attractive of course: basically bridging the gap between breadboard and production quality. But I really doubt that this device would be anywhere near hobby workshop tinkering range...</p>
