On the path to a new era in science.
In 14 days, we will be celebrating the opening of the Max-Planck-Zentrum für Physik und Medizin (MPZPM)!
The MPZPM is an interdisciplinary joint research center of Max Planck Institute for the Science of Light (MPL), the Friedrich-Alexander-Universität Elrangen-Nürnberg & the Uniklinikum Erlangen.

@mhkohne @sundogplanets That's true, but as referred to elsewhere in this thread, cooling would be the real killer. Cooling is very difficult without air or water with which to exchange heat, and it's always a significant design factor for spacecraft. An AI data center creates a LOT of heat.
A reporter just sent me a link to this: https://www.ycombinator.com/launches/LmD-lumen-orbit-data-centers-in-space
He wants to interview me about some fucking start-up company's planned 16 km^2 solar panels and fucking *AI data centers in orbit*
I think maybe I'll just walk into the middle of my hayfield and scream for a while instead. @Jason want to join? (Others are welcome too). Screaming begins in 5... 4... 3...
NASA is known for its cool tools, and the space agency has developed another: an autonomous underwater robot. A fleet of these robots will dive deep under Antarctica’s polar ice to help scientists better understand how rapidly the ice is melting due to climate change.

@j2kun Yeah, I was asking about FHE. The blockchain bit was just a joke. I can see why it's of interest for ethereum, but I'm pretty skeptical that the ethereum blockchain will ever be a useful computation environment (FHE or not) in the way web 3.0 boosters had hoped. Anyway, I'll take a look at the page you indicated.
Against my better judgment, I posted something similar on LinkedIn, and OMG the "stay in your lane" responses dominate. It's almost as if half the security professionals in this country see absolutely zero connection between national security and cybersecurity.
It's about f'in time the big publications pressed Mr. Trump on his statements this past week that supporters just needed to vote for him one more time, and then "you don't have to vote again." Trump's response -- which is that if he's elected "the country will be fixed" and their votes won't be needed -- seems pretty unambiguous. It is absolutely unreal that this is the GOP candidate for president, and that this blatantly antidemocratic statement alone does not somehow disqualify him from running.

@j2kun I guess I was assuming that FHE was still far from being practical (having not followed this topic much). Are you talking about something plausibly useful for some practical purpose or more of a proof of concept?
OTOH, I guess the real killer app for crypto would be if it could provide confidentiality and proof of work all at once. 😜
I'm not co-signing on this sentiment, but I admit it has some resonance. I don't feel so much that nothing worthwhile will happen online, I think there is interesting stuff happening right now, but I do feel that there was something special in that nascent, pre-commercial Internet that was amazing to experience and will never be recaptured.
I'm reading a lot about #ChatGPT4o and #htr, so I figured I'd spot-check it with this document: https://fromthepage.com/lva/va-revcon-74-76/work-7811594-024/display/33996304
The results were better than nothing, but still not great.
In particular, it was not able to read Lord Dunmore's name, nor read either of two references to "Emancipate our Slaves". If you've been following historical debates about the #1619project , you can imagine how problematic it would be to rely on this transcription for full-text search.
Can anyone point me to the source of this David Parnas quotation about certifying software engineers? "When someone builds a bridge, he uses engineers who have been certified as knowing what they are doing. Yet when someone builds you a software program, he has no similar certification, even though your safety may be just as dependent upon that software working as it is upon the bridge supporting your weight."
I’d hoped by now we’d see some substantial, effective legal challenges to existing LLMs’ reliance on stolen IP. In December we learned that Apple was seeking licensing deals with news publishers…and in June they announced their OpenAI partnership.
So long as vendors and end users have no serious legal exposure, there’s no market for ethical LLMs. That’s a real condemnation of the U.S. IP regime and legal system.
Theoretical physicist by training (PhD in quantum open systems/quantum information), University lecturer for a bit, and currently paying the bills as an engineer working in optical communication (implementation) and quantum communication (concepts), though still pursuing a little science on the side. I'm interested in physics and math, of course, but I enjoy learning about really any area of science, philosophy, and many other academic areas as well. My biggest other interest is hiking and generally being out in nature.
