spacetimeuser5··on Ask HN: Books etc. about Heisenberg uncertainty principle in CS, software?
I was listening to Science of Everything podcast by James Fodor (probably) on podbean.com for a 6 part "How computers work". He sort of is studying for a PhD or something, and he mentioned (in the 2nd part) that the uncertainty principle is actually applied in computer electronics for electron energies.
spacetimeuser5··on Ask HN: Whould you replicate a protocol of landing a coin on the edge?
I'd focus on coins only. There was a link on HN about some pilot study by some students, where they tried to emulate or used an actual mechanical hand or something similar flipping coins.

How? (though not in my protocol) For example, attaching a magnetic levitation system under the surface with the flipper unaware of it, and upon switching the current on through the system, the coin levitates probably on its edge. And it is a problem for the flippers and inference makers for not being able to arrange for such option.

spacetimeuser5··on Ask HN: Whould you replicate a protocol of landing a coin on the edge?
Consider the law of induction, according to which the fact that monkeys flipped coins for gozzilions of years with an average probability 0.5 doesn't mean they'd flip it with the same probability tomorrow.
spacetimeuser5··on Ask HN: Whould you replicate a protocol of landing a coin on the edge?
ok, won't read neither write it then.
spacetimeuser5··on Ask HN: Whould you replicate a protocol of landing a coin on the edge?
Suppose the protocol exists. It's not "gambling cheating" at all, it's not even "gambling", rather following some general methodological guidelines from quantum mechanics (least but not last). The question is to get enough subjects willing to replicate it.
spacetimeuser5··on Ask HN: Whould you replicate a protocol of landing a coin on the edge?
This has already been developed. The goal is to land a coin on the edge with more than 1/6000 probability.
spacetimeuser5··on To the brain, reading computer code is not the same as reading language (2020)
These MRI machines generate a rather strong magnetic field 3-5 T. Even if it is a minimal 0.5 T, natural Earth's magnetic field is much smaller ~5 × 10^(-5) T. Thus for ecological validity they should have checked that MRI MF really does not interfere with the measured brain function.

It can be somewhat ok to solve HackerRank type problems for 30 minutes in such MRI generated field. IRL programming sessions can take up to several hours. And let's see what quality of code would be produced or interpreted for hours in an MF 10000< times stronger than natural. Thus 80% of such neuroscience is non-scalable fragile bs.

spacetimeuser5··on To the brain, reading computer code is not the same as reading language (2020)
>>This network, whose activity is spread throughout the frontal and parietal lobes of the brain,

A (rare enough) person in chronic coma, regaining consciousness on a sedative-hypnotic drug zolpidem, which lasts for a couple of hours as long as the drug is active, can also show parietal lobes (and a bit of dorsal frontal lobes) activation (as showcased probably in Hamilton's Pharmacopoeia in a series on zolpidem).

Thus, according to modern neuroscience and brain imaging, reading code is basically the same as regaining consciousness on zolpidem while in coma.

spacetimeuser5··on New work extends the thermodynamic theory of computation
Sinclair is now using epigenetic regprogramming with OSK (developmental) genes to effectively regrow the severed optic nerve in primates and proceeding to humans. Levin has mouse paws cut off in a similar way and regrows them in a wearable bioreactor with a mix of drugs, which include not only "electroceuticals" (ion channel modulators), but probably also some (growth) hormones or hormone precursors (as he mentioned in a podcast they may use some estrogen precursor). Yea, they regenerate ~70% of the whole paw with multiple tissues, but the end result seems the same if it would be obtained by OSK reprogramming.

In a recent podcast #300 Attia was again mentioning the rather reliable benefits of caloric restriction. So thermodynamically it still seems ridiculous that by reducing the inflow of energy (at least the one of the most well-known type) the biological (and presumable computational) efficiency is increased at literally no cost.

Yes, biology is not as simple. With mTOR inhibition fasting is not a full story. mTOR is a sensor of food (amino acids) and a master regulator of growth signals. mTOR is inhibited naturally by fasting and artificially by drugs like rapamycin. And rapamycin is currently a winner in life/health extension across species (Matt Kaerbelin, Rich Miller from theDrive podcast). So with rapamycin inhibiting mTOR (or other fasting mimetic drugs) it's enough to only _send_a_signal_ of low energy/food to the biosystem to obtain gains in health and reverse biological time. So your analogy fits best here, as you are only using signals.

While with fasting it is a reduction of actual food/fuel. Garbage collection can be comparable to fasting-induced autophagy, but in fasting it is also an absence of growth signals like IGF-1 that provides gains in health function (though Greg Fahy research on thymus regeneration in humans with a mix including a growth hormone may contradict this).

The majority of Levin's work in developmental biology done in embryos, which are naturally a highly flexible tissue and naturally express high levels of Yamanaka genes, which are now used for epigenetic reprogramming (OSK). Growing eyes on the tadpole's tail is cool, but I want to grow a tooth for myself now.

If Levin wouldn't produce so much fluff on pseudoscientific concepts like "selves" and "computational psychiatry", he would have had the mice regenerate better and already proceed to humans, like Sinclair.

How would quantum theory explain the thermodynamics of increased mental clarity reported by humans on 3-5 day of fasting induced ketosis? Or multiple biocomputational benefits of mTOR inhibition (by e.g. rapamycin for longevity purposes), reduced rate of metabolism?

Extrapolating to modern mechanotech, this would be similar to an airplane flying faster and better upon regular reduction of fuel to it. Imagine a computer running more loads and faster upon regular reduction of AC power to it. Thus linear application of thermodynamics seems rather ridiculous and quantum theory may not save, because it disintegrates beyond the Plank's scale.

>>Every computing system, biological or synthetic, from cells to brains to laptops, has a cost.

Obviously so, fetching tiny potatoes from point A to point B by monkeys has a cost.

spacetimeuser5··on Cubic millimetre of brain mapped at nanoscale resolution
These data do not have a control group of healthy similar tissue samples, thus are not falsifiable, and are not 100% scientifically valid.
spacetimeuser5··on Cubic millimetre of brain mapped at nanoscale resolution
Try using the protocols and doses from the original article.

The cheap monkey headset works in a similar way: monkeys just essentially continue to analyze trajectories of medieval cannon balls in the LHC and to count potatoes in the form of bytes.

>> The sample was immersed in preservatives and stained with heavy metals to make the cells easier to see.

Try experimenting with immersing your brain in preservatives and staining with heavy metals to see how would you be able to write the comment similar to the above.

No wonder that monkey methods continue to unveil monkey cognition.

spacetimeuser5··on Cubic millimetre of brain mapped at nanoscale resolution
Yea, and at the Plank's scale resolution as a logical extension of the nanoscale with their "modern" measurement methodology this cheap monkey headset just disintegrates, haha.
spacetimeuser5··on 'So hot you can't breathe': Extreme heat hits the Philippines
Here you are, monkeys. Get now more of your cheap headset.
spacetimeuser5··on Daniel Dennett has died
Ok. And how many professors of medicine and doctors die under 120. Monkeys got really cheap headset.

>>realizing my brain no longer works.

So is it really you realizing your brain no longer works, or part of the brain with ownership of the rest realizing its brain no longer works?

P>S> To get still a full spectrum, let's not forget (rather rare) cases when people with 80%< of the brain filled with cerebrospinal fluid due to hydrocephaly were able to do uni math or work as accountants.

spacetimeuser5··on Ask HN: Why does Google Colab crash due to insufficient RAM?
I am testing this model https://huggingface.co/openai/whisper-large-v3, and I installed accelerate.
spacetimeuser5··on Ask HN: Which speech to text model would you recommend?
Is AWS speech-to-text (free tier) worth it?
spacetimeuser5··on Ask HN: Which speech to text model would you recommend?
This one https://huggingface.co/openai/whisper-large-v3 ? Do I need (and where from) to use CUDA from some google.colab or 4-core AMD Ryzen 3 4300U CPU on a laptop will handle it for an initial test program?

spacetimeuser5··on Ask HN: ChatGPT can't define parametric resonance. How can this be?
The first prompt was actually more specific, but it has provided the definition now. However it can't provide the specific numerical value for the specific type of parametric resonance. But whatever.
spacetimeuser5··on Ask HN: ChatGPT can't define parametric resonance. How can this be?
Yes, once. It was the first prompt like "What is ...?". The second prompt was like "Suppose you are a 20 Nobel prize winner in physics etc", and it failed after the second one also.
spacetimeuser5··on You do need a technical co-founder [video]
Can I offer intravenous DMT, ketamine or at least psilocybin (in various frameworks) for a technical co-founder, especially in such fields as bio/neurotech, AIxchemistryxhardware, as this may necessitate from the methodology of quantum mechanics?
spacetimeuser5··on Charlie Munger has died
There a tribe in Ecuador with reduced height studied by Walter Longo etc. They have a mutation in their growth hormone receptor, that means that they experience less effect of human growth hormone, hence reduced height. And their lifestyle is rather unhealthy: alcohol, smoking, sugars, junk food, obesity etc. Yet they rarely experience diabetes, cancer etc probably due to reduced mTOR pathway activation.

In the context of this specific post regarding Charlie Munger, you can't say that it's genetics unless you measure specific genes. He could be 100x Bryan Johnson, but Bryan Johnson at least makes his protocols open for use. And Munger didn't even bother to make a genetics test with his curiosity, thus providing no essential value to human civilization.
