The new recommendations tab on @ivory is pretty good! Really supports the point that some form of algorithmic discovery can be extremely useful for Mastodon.
Here’s to hoping that we’ll get a plugin system for algorithms. Free personalized algorithm choice for everyone.
We found that the PLC code actually contained logic that would lock up the train with bogus error codes after some date, or if the train wasn't running for a given time. One version of the controller actually contained GPS coordinates to contain the behaviour to third party workshops.
It was also possible to unlock the trains by pressing a key combination in the cabin controls. None of this was documented.

Yeah, I know, everyone else is sharing the article, but we need this message in the public consciousness: Working from home may reduce a person's carbon footprint by 50%.
A new #study published a few days ago is evaluating the #sustainability of Low-#Earth orbit #satellite broadband #megaconstellations.
The authors find that over 5 years, the #StarLink project would emit between ~0.5 and 1 tonne CO2eq per subscriber, and up to ~3 t CO2eq / subscriber for #Amazon's #Kuiper project. Those values are 31-91 times HIGHER than eq. terrestrial #mobile #broadband.

The growth of megaconstellations is rapidly increasing the number of rocket launches. While Low Earth Orbit (LEO) broadband satellites help to connect unconnected communities and achieve the Sustainable Development Goals (SDGs), there are also significant environmental emissions impacts from burning rocket fuels. We present sustainability analytics for phase 1 of the three main LEO constellations including Amazon Kuiper (3,236 satellites), Eutelsat Group`s OneWeb (648 satellites), and SpaceX Starlink (4,425 satellites). We find that LEO megaconstellations provide substantially improved broadband speeds for rural and remote communities, but are roughly 6-8 times more emissions intensive (250 kg CO2eq/subscriber/year) than comparative terrestrial mobile broadband. In the worst-case emissions scenario, this rises to 12-14 times more (469 kg CO2eq/subscriber/year). Policy makers must carefully consider the trade-off between connecting unconnected communities to further the SDGs and mitigating the growing space sector environmental footprint, particularly regarding phase 2 plans to launch an order-of-magnitude more satellites.
“'Children in the US can be legally married in 41 states, physically punished by school administrators in 47 states, sentenced to life without parole in 22 states, and work in hazardous agriculture conditions in all 50 states.' Over and over again, the worst states for children are clustered around the 'pro-life' Bible Belt, and the map of the states that are the worst for children looks a lot like a map of red-state America."
