I don’t think gdpr is required when it’s not a company running the instances?
Depends on whether your thing is intended for public or private use. If it’s just a static website to share files with friends and family or a chat service for a similarly limited group, then no, the GDPR does not apply.
Most popular Fediverse instances are clearly made for public use however.
if an instance is hosted in America, does it still apply
As long as it processes data of EU citizens, the GDPR applies. Whether the EU is able to enforce it is a different question.

I should have been more clear: The negative effects of quantisation. Obviously sampling into discrete values is shown but not the negative consequences that can have.
A DAC interpreting the blue trace will output something extremely close to the red one. There might be a slight bit of error in it due to the quantisation before but the graph does not show that and it probably couldn’t since it’d be so tiny. A good way to show quantisation noise would be a histogram with a signal in the middle and some quantisation noise around it.
The DAC would not output the jaggy line. It couldn’t, that’s not a valid analog signal. Painting the steps between the points can be done if your audience knows what that means but can be extremely misleading if it doesn’t. Those lines between the points with 90 degree angles don’t exist in the real world, they’re just interpolated between the points in the visualisation.
A much better way to represent digital samples in such a chart is the way it’s done in the wikipedia article on the topic: https://en.wikipedia.org/wiki/Sampling_(signal_processing). They’re just discrete points. If you did the same interpolation between the points as a DAC would do (which is not nearest-neighbour interpolation), you’d get the analog trace shown.
I missed that you said in private tabs. I can reproduce it there but BW also says that private tabs support is still experimental when you try to do it.
Quantisation is a potential factor but the graph does not show its effects and their comment describes the supposed effects sampling, not quantisation.
Also, when we come to discussing SNR, you’ll have to consider the SNR of analog systems too.
Sorry, I kinda missed your reply as it quoted the same source as the other one. Here’s what I said to that: https://lemmy.ml/comment/1611213
it seems pretty likely that EV batteries will see a second life after their first life in the EV
Why do you think that? In order for that to happen, this form of recycling must be significantly more economical than a new battery (which I doubt it currently is) because auto makers won’t recycle out of the goodness of their hearts, that’s for certain.
I haven’t seen any data pointing to BEV batteries being actually recycled to a significant degree any time soon. I’d love to be proven wrong on that but I have my doubts.
I have seen some pretty bad numbers usually from fossil fuel powered publications against EVs. Usually they’ll take the absolute worst case scenarios for an EV “Imagine all your power is coming from coal that’s being transmitted 6000 miles and from 1000 year old plants with 5% efficiency. See, EVs are just as dirty as ICE!”
See the paper linked in my other reply. It assumes the 2020 power mix in Germany which is quite terrible (only 55% low-emission) but not nearly as terrible as the US (40% low-emission according to your link). I could see the US getting closer to the 2020 DE power mix within the next decade or so though, so those numbers should be pretty representative of the future US. As mentioned in the other reply, the paper also contains an estimation for 2030 DE power mix.
Note that the article concludes that BEVs are not the future of transport but not that we should therefore use ICEs. In its conclusion it basically says that BEVs offer a good improvement over the status quo but we should really really have fewer cars instead. The focus of future transport should therefore lie on viable alternatives to cars such as walkable cities, cycling and public transport.
