Taking differences between degrees Celsius values is absolutely fine.

Ratios are undefined because the Celsius scale has no absolute zero while the Kelvin scale has.

We should have kept using nuclear? That nuclear of which refinement capacities are over 40% in Russians hands? For conversion it’s even a combined 63% for Russia+China.

The reliance on Russian nuclear fuel services is a consequence of decisions made decades earlier in U.S. made during Bush era and later Obama era.

"Following proposals from the International Atomic Energy Agency (IAEA) and Russia, and in connection with the US-led Global Nuclear Energy Partnership (GNEP), there have been moves to establish international uranium enrichment centres."

"The first of these international centres is the International Uranium Enrichment Centre (IUEC) established in 2007 by Rosatom at Angarsk in Siberia"

Reliance on Russian gas (which did increase after shutting down nuclear) is a bigger problem than relying on nuclear fuel: in nuclear energy fuel cost has much smaller impact on electricity cost than gas price for gas fired power stations.

In 2024, the EU imported a little over €700 million in Russian uranium products out of a total of €22 billion Russian energy imports.

Interesting article. According to it, the missing piece is scaling the conversion facilities from 8% to x%, and then scaling uranium enrichment process from 30% to x%. With that in place heavy dependency to Russia+China would have been solved, no?

By this measure, there is no "full spectrum" photography ever.

If you specify the source used for lighting, e.g. solar light, you can define precisely what "full spectrum" photography is, i.e. recording a bandwidth large enough so that any lighting energy that falls outside that range is negligible.

That's a website of Andrew Zonenberg if that name rings a bell.

It did not, thank you for the pointer, amazing stuff he's working on.

We also appear to be buying from the same supplier (Leo Bodnar).

Here‘s also an advice: if you want someone to listen, try not to come across like you just did.

Sure, I read that but your comment still sounds like it does. You're doing yourself no service.

We’re just BSing on the internet. No need to tone police.

That internet is elsewhere.

The dinosaur example lists an iPhone as source and none of their scanner models. It is also saying that it was recorded at a dinosaur theme park in Germany. This one might be meters long.

There is an extension called HN Friends that allows to add information to a tooltip for users and shows a hint that there exists such information.

Use this as you like.

Tracks 3, 4 and 7 at the station in question are not adjacent to a platform. It sort of makes sense to route a train over these if there is no stop planned there (intentional or not).

Here's the map of the station:

Of course it does. So it also makes sense that if you are operating that train, you make sure you don't end up on tracks 3, 4 or 7. You stop and verify that the signalling and routing is in place to let you stop at that station before it becomes too late and that option becomes impossible.

This is basic management, it's basic competence.

The train was misrouted because nobody cared about routing it properly: the driver, the conductor, the signallers, the routers, the management. Something weird happened and everyone shrugged and started to hum "Que sera, sera" to themselves, rather than committing to doing a job in the passengers' interests.
