First(?) SS body; beat Elon.
Ford has played with the idea as far back as 1936:

This series of three stainless steel cars was built by Ford and stainless steel producer Allegheny Ludlum Inc. starting in 1936, in order to showcase the benefits of stainless steel.

[...]

The first stainless steel Ford was the 1936 Ford Tudor Deluxe Touring Sedan, just six of them were made and the first was used by the New York Allegheny Ludlum sales office as a technology demonstrator of stainless steel’s durability.

[..,]

The second stainless steel model was the 1960 Ford Thunderbird, just two of these were built, the body, bumpers, and grille are all made from type 302 stainless steel.

[...]

The final cars built as part of this series were three stainless steel 1967 Lincoln Continentals.

If Doc Brown hadn't built a time machine out of one, would anyone today know what a DeLorean was?
Probably not. I bumped into the real thing in Inverness of all places last year at a music festival. The owner dressed up as Doc, the kids loved it, I managed to get an image too.

Not much, so far

I've encountered something I've decided to call 'The Legend of Superman'.

Recruiters these days are apparently looking for professionals who can do the whole thing: system design, circuits (analog and digital, high speed and RF, with simulation), FPGA design, layout, manufacturing, testing, programming (C and Python both), embedded OS, system level integration.

Wherever I've worked so far most of these were handled by specialists since these neighboring domains all requiring wide scope of knowledge in themselves - I'm yet to see somebody being professional in all of them in the same time... Must be some legendary guy...

I don't think there would be one person who would be worth their salt in all of those domains; that is why we want AGI.

Well, it seems now MacroHard has disabled the use of passwords, and will only allow passkeys. I was trying to change the one I had due to another blackmail attempt of releasing confidential files of mine they held, into the Dark Web, just to be cautious. Obviously, if they actually had something, they would have given me a sample.

Edit: Whatever happened to Freshmeister? I haven't seen him around for a while.
 

Someone Asked Physicists What They Really Believe About the Universe and…​

https://www.yahoo.com/news/articles/someone-asked-physicists-really-believe-140319144.html
Published by the American Physical Society, the survey queried over 1,600 experts from disciplines ranging from astrophysics to particle physics, along with a chunk of respondents who identified as “science enthusiasts.” The results showed that there’re still quite a few strikingly differing opinions on the standard model of cosmology, the scientific culmination of our understanding of our physical world which describes the origins of our universe and how it functions on a grand scale today.

“I think the most surprising finding was the gap between the public perception of scientific consensus and what scientists actually said when asked,” coauthor of the survey Niayesh Afshordi at the University of Waterloo in Canada and the Perimeter Institute told Gizmodo. “Ideas often presented as the standard view, such as inflation, string theory, particle dark matter, or a constant dark energy, did not command overwhelming support.”

The closest thing to a consensus came from the question “What is the Big Bang?” to which 68 percent said it was a “hot dense state — which may or may not correspond to a beginning of time.” But the flip side of that was revealing: just 20 percent answered that it was the “absolute beginning of time with a singularity at its start.”
There's more . . . :rolleyes:

Claude is telling users to go to sleep mid-session and nobody, including Anthropic, seems to fully understand why it keeps doing it​

https://www.yahoo.com/tech/ai/claude/articles/claude-telling-users-sleep-mid-211145615.html

Anthropic’s Claude is telling people to go to sleep and users can’t figure out why.

A quick scan of Reddit reveals that hundreds of people have had the same issue dating back months—and as recently as Wednesday. Claude’s sleep demands are varied and, often, quirky variations of the same message.

To one user it may write a simple “get some rest,” yet for others its messages are more personalized and empathetic. Oftentimes, Claude will repeat the message multiple times.

“Now go to sleep again. Again. For the THIRD time tonight…” it replied to a person with the Reddit username, angie_akhila. . . .
It might make sense if the interaction occurs between 0000 and 0600.

I could not find the thread on this so.

https://academic.oup.com/mnras/article/549/3/stag797/8703725?login=false

"Still accelerating: type Ia supernova cosmology is robust to host galaxy age evolution"​


Monthly Notices of the Royal Astronomical Society, Volume 549, Issue 3, July 2026,

Paper last year challenging the accelerating Universe, this paper says it is accelerating.

Perhaps one of the cosmo guys can paste it into the discussion

@Ibix @Orodruin @Drakkith and @PeterDonis I think were in that thread @PeroK will be interested I think also

I think you are referring to this thread, discussing the Son et al paper referred to as S25 in the paper you cite. @PeterDonis noted in that thread that the history of dark energy density implied by their model didn't seem terribly plausible. I'll have a look at the new paper.

Short version: according to the Wiseman et al paper, Son et al didn't account for known statistical biases and known galaxy age relationships in the data. They also conflated SN1a progenitor star ages with galaxy age, where Wiseman et al say it depends on how much star formation the galaxy has (lots of star formation means lots of young stars and lots of young star SN1as, whether the galaxy is old or young). When you apply existing models of SN1a brightness correctly the anomalous galaxy age dependence Son et al see goes away. Wiseman et al also tried applying Son et al's model to other data sets and found it doesn't match well (see fig. 3).

So Wiseman et al basically say Son et al messed up the analysis and their resulting predictions don't work. It'll be interesting to see if there's any come back.

Here’s something to think about: How come you never see a headline like ‘Psychic Wins Lottery’?
From memory "psychic" Sally shows 2020 UK had to be canceled due to Covid. The same happened at the end of last year when she was sick. So she can tell a perfect stranger how the year will end, but but cannot foresee
cancellation of her own shows? Or a global pandemic that will kill 7 million?

Perhaps she is not really psychic?

I thought this was funny: I was interviewing for a position, and the HR was paying attention, staring directly at me, to a degree that his level of focus was almost scary. Then,a few minutes latter, he stops suddenly, and utters "Hypocondriac. Hypochondriac, that's the word! "
