Ooh, that's a worthy challenge. Of course, I can imagine getting enough data on all of those cities and deciding to launch everywhere else but not Boston "because your roads are garbage and you all drive like you're impaired 24/7" :-)
Heh, in the early days of C++ (1990ish) I had a notable application of 3+4 involving a doubly linked list with cache pointers (time-sequence data browser so references were likely "nearby" as the user zoomed in; spec was to handle streaming data eventually.) Had problems with it crashing in pointer-related ways (in 1990, nobody had a lot of C++ experience) so I cooked up a really dumb "just realloc an array" version so I could figure out if the problem was above or below data structure... and not only didn't the "dumb" version crash, it was also much faster (and of faster order!) due to amortized realloc - doing a more expensive operation much less often turns out to be a really good trick :-)
Listing alumni degree year is generally an "insider" thing (noone who isn't also a Cornell alum really cares which year, especially for a bachelor's degree; likewise Cornell doesn't mention the Harvard '95 PhD in Applied Physics, even if it's probably more relevant to the work...)
"insider" thing, you can be certain that an exempliary mind such as his did not get fired up in a vacume, and that 90, was a year and place that likely produced an iteresting mixed bag of characters, or in other times would be refered to as "schools of thought", and then some went off to bell labs which still functions as an intelectual singuarity that leaks concepts through it's event horison ocasionaly, or in this case displays time dialation effects.
On my Polestar 2, I was surprised how in actual use, friction braking was basically zero - to the point where when you start a trip the brakes are used for a few seconds to make sure they're still working (and scrub them a bit.) In actual driving - without trying particularly on my part - it's just always regen.
Somebody recently used a variation of this to get good video of welding - basically a camera synced with a very bright (strobe-ish) light, brighter than the weld itself, so you adjust the camera to the ludicrous-but-consistent brightness level and get details of the weld and the surroundings. https://www.youtube.com/watch?v=wSUxK8q4D0Q (Chronos "Helios", from early 2025)
Same - but mine are also primarily so I can hand out links to specific articles - they're not hidden but they're not advertised either (and they're static sites with almost zero logging, so I wouldn't really notice either except that this site has a published list :-)
Interesting detail on the algorithm but seems to completely miss that if you care about non-streaming performance, there are parallel versions of xz and gzip (pxzip encodes compatible metadata about the breakup points so that while xz can still decompress it, pxzip can use as many cores as you let it have instead.) Great for disk-image OS installers (the reason I was benchmarking it in the first place - but this was about 5 years back, I don't know if those have gotten upstreamed...)
I'm surprised that this shows anything running usefully on my 2021-era thinkpad (with "Iris Xe"'TigerLake graphics) which inspires me to ask - are external GPUs useful for this sort of thing?
Particularly because, although there are smaller "study" versions as he worked up to it, the painting itself is 10 feet wide and most references don't include that context (at least not visually, they often list the numbers.)
Some of their earlier videos go into a lot of detail on the safety interlocks (including that the radiation near the device can be lower than ambient because it's basically a large chunk of shielding :-)
As for pricing, https://news.ycombinator.com/item?id=45392896 had some numbers from 5 months ago. It seems like the kind of thing that you'd want as a nearby service, unless you needed to do continuous inspection (they have some automated conveyor sampling products too, it looks like.) My last company had a few 3d-printed components that would have been interesting to spot check after wear testing, but for a lot of things, the competition for the scan is "open it up with a screwdriver" :-)
