If you add 5.1kΩ pulldown resistors on the CC lines for USB-C, you can get the standard 5V without a handshake although current may be limited by some chargers without negotiation.

I don't know if you have already played it, but https://contexto.me/ is probably the best UI I've seen for semantic word guessing games. It is simple enough that it can fit on a phone screen and only displays the rank of previous guesses in a bar that fills up more on guesses that are closer

homogeneity is only optimized for a small volume within the bore. Regardless, the superconducting coils will still experience a change in Lorentz forces as sequences are run, and noise from other components will still be "heard" by the main magnet

high pixel count != good quality. With all of the smartphone cameras, the sharpness in the details is poor that the image quality is comparable to a mirrorless with half the resolution or less. And then there's low light performance and artifacts which the computational photography introduces

It does, and it's a very good game, but this feels like plagiarism with how similar it is -- artwork style, mechanics, even UI is essentially identical to the GBA games

this sounds like progress, but it is still very bad except for highly repetitive music like the EDM examples they give, and even then, it still can't get tempo right

this can produce some pretty disturbing, but interesting music using the prompt "energetic music, violin, voice, orchestra, piano, minimalism, john adams, nixon in china": https://www.stableaudio.com/1/share/953f079e-d704-4138-904c-...

Even though this is tangential, I think it's important to note that this experiment should be called as the Millikan-Fletcher oil drop experiment to acknowledge Harvey Fletcher's contribution to this experiment as a grad student which he was coerced into relinquishing to receive his PhD

I read it as: for the same calculation, what would have previously taken 5,000 CPU cores * hours ran on a supercomputer can now be run in 2 milliseconds on a desktop. Or about roughly 10 orders of magnitude faster

And if it is ever needed, let's hope the stockpiles and logistics are in place to allow for quick distribution of the drug to broad portions of populations which are affected. We saw with COVID-19 that the U.S. let the Strategic National Stockpile become depleted. In the worst case, let's hope the drug has been maintained to be immediately available.

This is factually incorrect. This HOPO 14-1 chelates f-block elements, many of which are radioactive, without depleting other metal ions from the body which are essential for metabolism and other functions. Also, there are a large number of agents which can mitigate the damage done by radiation exposure when administered prophylactically
