Probabilistic computers have data that can flip between two states with a tunable probability to help solve optimization problems that standard computers struggle with. Scientists have just built one with one million p-bits. https://spectrum.ieee.org/biggest-probabilistic-computer?utm_source=mastodon&utm_medium=social&utm_campaign=fedica-Mastodon-Daily-Pipeline

Videos intended to hold people in power accountable are being run through surveillance databases and may later be used to identify some of the same people who made the footage. This is the surveillance ouroboros. https://spectrum.ieee.org/unintended-consequences-video-surveillance?utm_source=mastodon&utm_medium=social&utm_campaign=fedica-Mastodon-Daily-Pipeline

The reasoning given by the Trump administration for shutting down wind farms was due to concerns about interrupting military radar and sonar. But now offshore wind farms can be integrated into national defense programs, boosting sensing technologies. https://spectrum.ieee.org/offshore-wind-military-radar?utm_source=mastodon&utm_medium=social&utm_campaign=fedica-Mastodon-Daily-Pipeline

While we don't have access to the astrophage from #ProjectHailMary in real life, scientists are designing space probes that rely on the same basic principle it uses to travel between the stars: very low mass objects accelerated to very high speeds using photons. It would take these probes about 60 years to reach Tau Ceti. https://spectrum.ieee.org/high-speed-interstellar-travel

The UK has a power transmission problem. Wind farms in Scotland are producing huge amounts of energy, but getting it flowing to London in the south is costly.
New grid-enhancing technologies allow more #power to be transferred across the grid, without building new power lines.

Computer #programming is, at its core, creative. If you’ve lost your spark, try checking out one of Daniel Temkin’s 44 esoteric coding languages. It’s not about making sense, it’s about stretching the limits of what a programming language can be, and what a community of programmers can do together.

A new solar panel is here that concentrates the sun’s light onto smaller areas. It extracted about 50 percent more power than previous designs. It’s also cheaper, using less than one-thousandth of the expensive semiconductor materials required by normal panels. https://spectrum.ieee.org/solar-panels-micro-cpv?utm_source=mastodon&utm_medium=social&utm_campaign=fedica-Mastodon-Daily-Pipeline

New grid-scale battery sites in Scotland are stabilizing the power supply with their ability to quickly inject power and current during emergencies, just like fossil fuel plants do. One site already proved its worth when it leapt into action after a wood-burning generator unexpectedly shut down.
