... And here's the first three orders mentioned in a famously quoted press conference from 2002:

Are you anywhere near (the remains of?) a canal network? That was how bulk cargo was generally transported in the 18th century. First-mile + last-mile would be by wagon, of course, though usually pulled by oxen, not horses. Canals were economically revolutionary, for 100-150 years, until railroads largely supplanted them. They remained viable, in limited circumstances (ie, some routes for some cargos), until the mid-20th century.
Astute observation; no canal, but there is a river outflow to a bay, whereby a ship could have carried stones from the quarry, albeit a long way around a peninsula; it is possible that was a more effective way to get them close, and then use horse and cart to get them the last bit of distance.
Thinking about the logistics of such a feat at that time is wild to me for just the construction of a private residence.

I'm surprised the raw materials came together over such a distance. That transporting lumber was economical back then is remarkable.
I live in a late 18th-century rowhouse where there is large stonework for window sills/surrounds/doorways all done in a very specific pink granite that was carved from a shoreline quarry a significant distance away. Massive stones, 100kg+ each, had to be transported by horse-drawn cart, over not-easy-terrain, a distance that would have taken two horses probably 8-9 hours per trip, and enough stones that it was probably 15-20 trips. Let alone the effort that had to have been required to carve surprisingly square/cuboid shapes from solid granite without power tools. It's mindblowing to me that someone was able to afford such a home construction, let alone the time taken to do it, in ~ 1790. It isn't a particularly rare style in this neighborhood either.
Fast forward 200 years, and I was sweating at the cost just to hire someone to deliver new hardwood countertops from a place not much further away. By truck. By a single person. In a single afternoon. No horses required.

Whenever I see press on these new 'rack scale' systems, the first thing I think is something along the lines of: "man I hope the BIOS and OS's and whatnot supporting these racks are relatively robust and documented/open sourced enough so that 40 years from now when you can buy an entire rack system for $500, some kid in a garage will be able to boot and run code on these".
For Christmas I got an alarm clock that basically doesn’t function without a $50/year subscription. For an alarm clock (Hatch.co).
Consumers need to get better at understanding TCO when buying things. Or maybe the government should be slapping those “annual cost” stickers like they do on washing machines to understand how much electricity they use.
Paying a subscription for an alarm clock. I've heard this one before! [1][2]

The Guardian article glosses over a few things that are actually interesting about this ship:
- It's made out of aluminum instead of steel. The resulting weight savings make it a bit more efficient. That's something this shipping yard specializes in.
- Because it is going to run in shallow water on the river Plate, it doesn't actually have propellers but a water jet propulsion system.
Fully charged did a video on the construction of this ship early last year: https://fullycharged.show/episodes/electric-ferry-the-larges...
The project of getting this ship from Tasmania to South America is also going to be interesting as well. It can't do it under its own power; it's designed for a ~50km crossing, not a trans Pacific/Atlantic journey. At the time, they were thinking tug boats.
I'd wager they will use what is known as a 'Float-on/float-off' ship for transport... it's rather common actually-
It's a ship with a very low deck line that partially submerges itself, with the center of the deck underwater deep enough so the other vessel can 'float on' over the deck. They they pump the water back out, raising the deck above water and the boat on top it just rests flat.
They do this for some oil rigs as well.

Given the reputation for the cost and provenance of the cameras I'm surprised that Hasselblad passed through QC with that solder spooge at the edge that got into the frame of the film. I mean... it's visible on all the photos. I'm surprised that someone didn't notice that in testing before the camera left and send it back. Hell, even if I bought a cheap camera today and every photo has a little unexposed notch in the edge I'd be pissed. If you told me a camera was going to the moon I'd think I'd want the frame to be flawless....

The table lists F1 cars as having "Carbon fiber brake calipers".
This is glaringly incorrect. All current brake calipers are machined from aluminum, specifically Aluminum-Lithium or Aluminum-Copper alloys. There is a rule denoting bulk elasticity modulus limit on brake calipers of 80 GPa, which was set just at that to allow the more exotic Lithium Aluminum alloys but to dis-allow Titanium alloys or anything else stiffer (There was experimentation with Titanium calipers in the past.)
Absolutely no calipers are made from composites, CF, graphite, or otherwise. Discs are Carbon-carbon.
So what the hell part of the EU are you talking about where they don't ask for any ID at the point where you are boarding, whatsoever?
For reference, here is Iberia's page for required ID when flying, and I've seen that this is absolutely enforced every time when checking in and boarding.
