>Not bad!

Its terrible. This is totally not how GPS works, I.E. the terminal never sends a message to the satellite. This is the danger of early LLMs, a large amount of their output is false and there is no way to tell unless you are already an expert.

This makes them basically useless except for a toy.

There is a big difference between infinite and very high gravity. Neutron stars have only about 50% time dilation on the surface, as the surface is at about 50% their Schwarzschild radius.

I read somewhere (if someone remember it, please tell) a short history about life in neutron stars. It would be incredible fast due to the abundance of energy, with the evolution from 'stone age' to computer age happening in milliseconds.

Due to being in a deep gravitational well, such life and life inside a star are forever isolated from us. Unless they discover a way to use solar flares, in fact, perhaps solar flares are their way to escape the surface of the sun.

While superficially similar, BitTorrent and a blockchain are inherently different designs that target different problems. Blockchain is massive data replication, BitTorrent is massive data distribution (with some replication too).

That's why you can actually attack and shut down a bittorrent network, by targeting the index servers, that are not massively replicated. I.E. The Piratebay is often down.

As a solution for this, I'll shamelessly plug my small project here, that combines bittorrents with the blockchain as a invulnerable piratebay-like bittorrent index server, called Blockchain Bay: https://github.com/ortegaalfredo/blockchainbay

It's command line, and don't use any tokenomic scams. You pay the blockchain only for the data you need to upload, that is fortunately, very little as bittorrent magnet links are very small.

Be careful with the redefinition of words, as it's a basic 101-mind-control-technique.

What's the difference between this and the Diffusion bee? The DB project has not been updated in a while.

I know that I never detected them. Also it never crashed nor malfunctioned in any way (thanks in part to Linux), so any undetected error didn't caused any problem.

I have a lenovo P52, it came with 16 GB ECC. The dimm is not super-expensive, but it's hard to find, and only comes in half the size of regular dimms.

I replaced it with non-ECC memory and never had an issue. In fact you can combine ECC and non-ECC memory without any problem.

I have 128 GB of non-ecc memory in my notebook, never detected a single error, and has been on 24/7 for more than 4 years.

Unless you live over 4000 meters over the sea level, like to compile while flying or live close to an unshielded nuclear reactor, you don't need ECC.

And most memory problems you can fix by better cooling, and better shielding.

With correct encoding you can detect signals way below the noise floor. Thats how GPS work, you detect a satellite signal orbiting at 400 km with an antenna the size of a chip.

The Curiosity rover communicates with Earth from Mars with an antenna the size of a soda can.

Your calculation is likely wrong. See, you can build a laser in a spectrum not generally emitted by stars, and point directly to another star system. You dont need much power, yes, perhaps some terawatts, but it can be pulsed, total energy would be low.

And getting a low power signal doesnt means its impossible to detect, but that the bandwidth is short. Instead of 200 bits per second, you would get 1 bit per hour. But that´s enough.

> isn’t 1 million a frighteningly small sample to draw conclusions from?

Sample size in a survey will just give you more or less error. You can calculate exactly the expected error of such sample size.

The article is brilliant until observed.

I saw that wormhole article and something in it triggered the bs detector. Those discoveries are often made by a big team in a big lab, the article only named one researcher.

IMHO Quanta is far from the most respectable source of science news, since their articles tend to be very sensationalist, but in this case Quanta is not to blame, as the article it was published in Nature, but publications in big magazines are becoming more and more political, and less about real science.

I believe he's mostly right except that he need a hardware breakthrough, the same way mobile phones had a hardware breakthrough in 2007 with the invention of good enough LCD touch screens and batteries. VR and AR is much harder but not impossible.

>By spreading, I think you're referring to interleaving https://en.wikipedia.org/wiki/Burst_error-correcting_code#In... , which doesn't need randomness.

I stand corrected!

Also, how RAID works, and how ECC memory works.

One important stage of error correction is spreading, that use a pseudo-random function to 'spread' the damaged data over several blocks that can be then completely recovered, instead of concentrating the damage in a single block (like often happen in erasures) that cannot be recovered.

There are many types of Reed-Solomon codes, each with different amount of redundancy, they are a special case of BCH codes, a kind of code that approach the Shannon limit (the maximum rate of error-free data that can be transferred over a noisy channel). The bandwidth of a channel (like radio, or optical fiber) is not really limited by the media, but only by the noise it has. Optical fiber have almost zero noise, that's why they are so fast.

There are much better codes nowadays that are closer to the Shannon limit, like LDPC, or convolutional codes. But they are usually much more computationally intensive. They are used in space probes where computation time don't matter, but you often have channels with much more noise than signal.

I keep a repo of C implementation of several error-correction codes including Reed-Solomon, that can be used as standard unix filters like gzip: https://github.com/ortegaalfredo/eccchain

Powerful people are pulling strings to control AI everywhere. OpenAI is exactly the opposite of open. Now someone is pushing on Stability AI to close it up, I believe those models are more powerful or dangerous than they seem, and it got some people scared in some way.

I read than when some guys from 4chan started running the leaked NovelAI model, they generated porn non-stop for 20 hs or more, no sleep, no eating.

>There are infinitely many truths

Obviously not.

EVs are just marketing, they not much more efficient than gas cars, it just moves the energy source from fossil fuels to...well, nuclear at best, or centralized fossil fuel generators at worst. You are not fixing global warming with EV cars.

A small, dirty, gas moped is way more efficient, cheaper and green than the greenest EV car.

The real revolution is electric bicycles, unsurprisingly one of the most popular means of transportation in China. I saw an excellent graph that I can't find at the moment, which shows that a human on a bicycle is 10 times more efficient than the most efficient biological locomotion known (that of fish).

There is always a cyberpunk feel of weird hardware and weird OSes clobbered together with wires and sticky notes.

Psychology is a pseudo science because it doesn't not make testable predictions.

>but the more important thing is not to go into such flamewar territories in the first place.

It may be more important to you, but I don't care. For me, truth is important, and I wrote the truth.

Tuition in many colleges is over 80k usd/year.

>It should be virtually free to go to college

If you are going to invest into something, it should be good investment that gives returns. An Useless degree clearly do not give enough returns not even to pay for itself.

> Many jobs that don't require a college degree hire college grads because they can get them

Exactly, that's the scam. Requiring a 'Tax' that you pay the college that is nothing but a useless piece of paper, that makes you lose years and enslave you in debt.

> followed by crypto (which is a glorified pyramid scheme - prove me wrong).

It is not wrong, but as long as it replaces the far, far worse pyramid scheme that is Fiat, I'm fine with it. But we digress :)

I can imagine many, which are not only useless, but also malicious and generally negative for society. I won't name them here so as not to 'offend' people, but it's easy to tell which ones I mean.
