peter303··on Could you train a ChatGPT-beating model for $85k and run it in a browser?
Every parameter needs to reach every other parameter. Ideally enough core memory for that. But their tiling algorithms.
peter303··on The False Promise of ChatGPT
I wonder if proper curation of training input, generative AIs could fix the deficiencies (creativity, morality) Dr. Chomsky points out. Right now the training model is put-everything-in data training. That may cause the uneven results we see in early chatbots.
peter303··on There’s no such thing as a tree phylogenetically (2021)
Poet Joyce Kilmer would be disappointed.
peter303··on Taiwan is a vital island that is under serious threat
I can see much of the paywalled article. But I hope it mentions the recent book Chip Wars about how TMSC became the worlds leading high end chip manufacturer. However even they are dependent on international expertise like Extreme Ultraviolet lasers. A Taiwan war could bring international semiconductor manufacturing to a full halt. We have seen previews in covid slowdowns and large 1990s earthquake,
peter303··on Taiwan is a vital island that is under serious threat
The Independent-Taiwan political party has been growing as most mainland refugees have died by now. Peking is unhappy with this trend.
peter303··on Academic urban legends (2014)
When I wrote class term papers in the 1970s I spent days in the massive book stacks of Harvard libraries. I suspect many urban legends about love-making, deceased souls, and crimes in the stacks may true. Like in the movie The Paper Chase.

I dont know if Harvard Libraries has warehoused most their physical books like many other college libraries. One has to order up old books then.

peter303··on Academic urban legends (2014)
Papers now have Data Objects of Interest reference links which are a smarter URL. When Ireview modern papers I am supposed to check all doi's work.
peter303··on The mission to discover if Jupiter’s moons support life
Apollo and Artemis dose the expensive, fast trajectories due to protecting human life. There is a mission currently enroute to the Moon that will take months due to a frugal propulsion system.
peter303··on The mission to discover if Jupiter’s moons support life
The current Juno probe flies in 53 day orbits where only a few hours are in heavy radiation. It has made 48 orbits. The mission has been extended 7 years to 2025. If Juno runs low on fuel or the hardware breaks down, it will be crashed into Jupiter to avoid hitting and contaminating a moon.
peter303··on The mission to discover if Jupiter’s moons support life
Its a good hypothesis that life start at deep volcanic vents. Geologist Robert Hazen conducted lab experiments showing that all steps of the metabolic citric cycle occur in this environment without needing catalytic enzymes. Chemical reduction of magma provides the energy. As life developed enzymes to improve metabolism, it could migrate to colder, lower pressure environments.
peter303··on The Hollywood sign debuted 100 years ago
I remember hiking up to the base of letters in the early 1990s. I think there is a substantial fence now.
peter303··on Gattaca is still pertinent 25 years later
You mean they dont still use 1980s computer screens in 22nd century Star Trek?
peter303··on New AI classifier for indicating AI-written text
OpenAI archives every request and output text. Why not compare suspected A.I. text against this?
peter303··on Has Earth’s inner core stopped its strange spin?
2022 or 2023 might need to SUBTRACT a leap second because the whole Earth's rotation has mysteriously sped up about a millisecond. Since the definition of the year switched to atomic seconds some years ago, they previously had needed to ADD leap seconds to sync to the astronomical year. Earthquakes, weather, ocean circulation can change length of day. Perhaps the core rotation changes may be affecting the whole Earth too.
peter303··on Has Earth’s inner core stopped its strange spin?
Russian seismologists made artificial earthquakes up to M6 with nukes in the 1950s and 1960s under its peaceful nukes program. These data remain some of highest quality seismic data ever recorded.
peter303··on Has Earth’s inner core stopped its strange spin?
Seismic waves and ultra high pressure mineral lab experiments.

Seismic waves suffers from antenna limitation artifacts with the 70% ocean barely instrumented. A French group launches torpedo seismometers for months at a time to fill in gaps.

peter303··on Has Earth’s inner core stopped its strange spin?
In 2 billion years, the 2200 km outer core will completely solidify, with the magnetic dynamo halting sometime before then. The solid core is growing/solidifying a millimeter a year.

With no magnetic field there will be more harsh radiation at the surface. Plus the solar wind may erode away the atmosphere as has on field-less Mars.

peter303··on CNET's AI journalist appears to have committed extensive plagiarism
Managers are figuring out how much money they can save replacing human journalists with AI.

Computer generated articles are routine for boilerplate like financial summaries, sports results and police reports. But now creeping into more substantive articles.

peter303··on Ask HN: What is the weirdest or most surreal recent technology you have seen?
Some of the VR movies are getting quite good. First the newer generation headsets- 2K, 90+ fps, cableless- no longer induce nausea. Second, movie makers are becoming versant with the strengths and limits of this media.

One I saw in December called Container, I felt I was in the room with various scenes of realistic 3D people.

peter303··on GPT is all you need for the back end
The 5% to 10% of the output that is factually wrong or socially inappropriate could be a legal nightmare.
peter303··on Learn Lisp the Hard Way
LISP was the introductory computer class language at MIT for nearly 40 years. The faculty felt it exhibited the important elements of programming and algorithms. Some students complained they wanted something more practical for getting a job. It appears the newer faculty replaced it with Python.
peter303··on U.S. moves to seize $460M Robinhood stake linked to Sam Bankman-Fried
70% of Madoff victims contributions recovered by 2022. In 14 rounds.

https://abcnews.go.com/Business/funds-recovered-victims-bern...

They only get contributions back with no earnings.

peter303··on Casio-F-91W die-shot
I have probably ten- not precisely the same model- in the past thirty years. Most common failure is strap breaks after taking the watch off for swimming every other day. Second most failure is to shatter a corner due sports- hit my wrist on something. Third is a humidity leak when I visit the US South in the summer.
peter303··on My experience with check fraud
The only physical check I have written in the past four years was to the US Passport Office. They refuse any electronic payment method.

The next most recent paper check was a wedding gift. But modern wedding registries accept digital payments now.

peter303··on Grad student unions strike deal with University of California
My department at Stanford has a diversity administrator, a fund raising admin, a sustainability admin, and some more I am probably not aware of. Only senior admins get six figures.
peter303··on AI's Jurassic Park Moment
Its not that A.I. software is smart, but that for the most humans are mediocre and uncreative. Humans are stuck in their mental ruts. Given a large enough A.I. and large enough sampling of total human knowledge, an A.I. can predict much human activity.
peter303··on How hospice became a for profit hustle
Several of my acquaintances and relatives benefited from hospice. There was less red tape in obtaining financial approval than curative medical care. Less wrangling with insurance company gatekeepers.
peter303··on How thick is a three-sided coin?
Take sphere. Divide the surface into N equal parts. Roughen the surface so it stops quickly after rolling.
peter303··on Beyond Meat is struggling, and the plant-based meat industry worries
Trying to imitate meat van only go so far. Ordinary plant products have their own flavors and textures that dont need to copy meat.
peter303··on Oldest software system in continuous use
Or ribosomes in every living thing translates mRNA into protein. Over three billion years of generic evolution the ribosome amino acids differ considerably between far apart species, yet retain their function.

Before DNA sequencing became efficient, a particular protein inside the ribosome was used to study genetic divergence.
