> allthough one would think they'd get 0% alcohol related cancers

I assume "alcohol related" in this context means that alcohol consumption increases the risk for those types of cancers, but you might still get those types of cancers even if you have never consumed any alcohol. And "less than once drink per week" is assumed to be almost the same as never consuming any alcohol at all, so 17% is the risk for women who never consume any alcohol.

Perhaps a reference to Pangea Proxima?

Life might very well exist on earth even through those conditions, but not to the extent we have today.

Unreliable as in noisy in a way that I could not fix with temporal averaging. I tried to guide a robot arm to pick up the top object in a bag of evenly colored objects, but RealSense gave me randomly fluctuating values and rather large undefined areas (areas that were blocked from the view of one of the two sensors). The ToF sensor gave solid values even outside when it was snowing. Of course the ToF sensor had other problems, high requirements for power and cooling, and perhaps worse performance in very strong sunlight.

I've tried to use Intel RealSense in the past but found the output to be unreliable. I had much better results with Chronoptics KEA:

Is "ateljé" (meaning art studio) really the correct Swedish translation here? I suspect "etta" (meaning one-room apartment) would be more suitable.

Unfortunately sometimes even experienced people make mistakes that a recent graduate should not do (but in practice sometimes does). AI models can help avoid mistakes that in hindsight were obvious and should never have happened.

Domesticated cats survive so well in the wild that they have eradicated several other animal species:

Privacy is a safety concern. If some government agency can control your car remotely, chances are that others also will find a way to do that.

Integers are simple to parse, but from_chars is a great improvement when parsing floats. It's more standardized on different platforms than the old solutions (no need to worry about the locale, for example whether to use comma or dot as decimals separator) but also has more reliable performance in different compilers. The most advanced approaches to parsing floats can be surprisingly much faster than intermediately advanced approaches. The library used by GCC since version 12 (and also used by Chrome) claims to be 4 - 10 times faster than old strtod implementations:

Rust was created at Mozilla and currently 11.7% of the Firefox source code is in Rust:

That's down from 12.49% at the peak in July 2020 so I assume the conversion work was halted after the layoffs in 2020:

Roughly the same as the difference between a country and a business.

Stora Enso has 20000 employees and roots in the 13th century. In the 17th centry Stora produced two thirds of all copper in the world.

"The oldest preserved share in the Swedish copper mining company Stora Kopparberg (Falun Mine) in Falun was issued in 1288. It granted the Bishop of Västerås 1/8th (12.5%) ownership, and it is also the oldest known preserved share in any company in the world."

In my experience a few email services refuse to accept emails from AWS SES, probably because a lot of automated emails are sent from AWS SES.
