It is sensitive - most modern authoritative DNS servers will do fully automated DNSSEC signing and key rolling at quite short intervals (like 1h) so if time is off at the validating nameserver it will think the signature is expired/not yet valid.
The same applies to apt package signatures (~1 day) and TLS certificate validation (~3 months)
@copyme And, as some have already pointed out, they are actually suppressing freedom of speech while at the same time speaking of introducing laws to guarantee* freedom of speech in social networks!

A popular #bitcoin #ethereum narrative:
> it's all powered by surplus electricity from renewables
I'd love to be proven wrong, but:
1) It's true that surplus energy from variable renewables *can* be burned by BTC mining
2) There's no evidence it's actually is being done
3) 70% mining is done in China, where variable renewables were 3% in 2018
When supply is limited the scale does matter.
The per-capita #CovidVaccine progress in UK (population 80m) can be also described as a "fiasco" when compared to that in Israel (population 9m).
And EU population is 450m.
I have mixed feelings about this publication - on one hand, illustrating an article about economics of nuclear power by a picture of an exploding liquid gas (!) tank is kind of out of the blue, on the other hand it kind of highlights that fossil gas is actually much more dangerous than nuclear power.
I guess I'll just settle on an opinion that a scientific article illustrated by tabloid-style photos isn't really too scientific.
@kravietz @cjd Great point about the missing education for adults.
Scientific and technical progress creates a growing need for life-long education: the world and our understanding of it is changing too fast for knowledge and skills to remain relevant for decades.
At the same time social progress should (but because of growing inequality often doesn't) create enough prosperity for adults to have enough leisure time to spend on life-long education.
We need to fight for the 8 hour work week.
