I do like the evolution of black hole illustrations. They change every few years, mostly based on depictions by hollywood, the latest being Interstellar. The current trend, the symetrical ufo-shape, is scientifically more accurate than the previous whirlpool but isnt perfect. It doesnt show the red/blue shifting. If you were actually looking at one with human eyes, you would probably see a rainbow effect. One side would be blue/white other red/black, with variations inbetween. But every attempt at such rendering just doesnt look as intimidating or magnificent.

It is like dinosaurs on TV. Over the years they have gone from naked lizards, to having feathers, to being almost furry, and now back to naked again as hollywood balances science with audience expectations.

This sort of thing.

I am sorry, what? 40 tonnes of basalt dust per hectar?? What's hilarious is that when you look up basalt dust on internet, merchants sell it in bags of 2kg, "to be applied 20 grammes/sq meter", while 40t/ha is 4kg per sq meter!

UBI is the "forever ticket" that insures the status quo when UBI is institutued will be the people in power forevermore. UBI is the means in which the 1% seal their and our fates forever, because there is zero incentive to change or improve a system where all power and decisions are performed by ignored automation for a powerless, uneducated and education-incapable 99%, while the 1% in power wallow in excess.

> Christopher Howe at the University of Cambridge and his colleagues built a small enclosure about the size of an AA battery out of aluminium and clear plastic.

That's REALLY not a lot of power, which of course is reasonable, but I do wonder how far can it scale, can it reach any generally usable.

Let's take a very conservative estimate of watt-hours of an AA battery of 2 Wh.
The computer used in the paper could run for 2,000,000 µWh / 0.3 µW = ~6,666,666h.

Let's convert to a more human friendly numbers:
6,666,666h / 24h = ~277,777 days.
277,777 days / 365 days = ~761 years.

I probably calculated all of this incorrectly, but I still have a feeling that blue-green algae might not be very scalable... :/
Well, website is a wrong name, the correct would be RSSSite, something easy to follow from a personal aggregator, witch happen to be a classic feed reader.

Doing so means:

- you can select a moderately large set of sources (depending on how much posts are published and how much you read) and see the aggregated by YOURS criteria on YOURS own local machine, no propaganda from some giant can tweak your sources hiding something or pushing something in your "view";

- you can keep anything you feel relevant locally, depending on your reader with a single click and full contents, fully searchable/tagable/sharable etc no dependence on "web archive services" that might disappear or even get silently tweaked to change the history;

- you can organize your view of human information depending on your tastes, run your own statistics, analysis etc to form your own personal knowledge out of someone else published ones.

The above is the key toward a free information for a free society, depending on third parties doing something equivalent, like Google News, means being at the third party mercy since such hoster can push you toward certain contents hiding certain others with criteria you do not control. At a scale means classic full-fledged dictatorship propaganda because while freedom of publishing is still there nearly no one can reach "unwanted by big&powerful contents" since access is via aggregators and search engines.

That's why we need classic mail, usenet and RSS: because no one can control them at a whole level. They are decentralized services anyone can control just a personal slice.

I worked in three different healthcare technology companies (for doctors, pharma, and insurance).

1. In not a single case was compliance with HIPAA rules ever a cost center beyond the initial project to implement controls, and that itself wasn’t a huge project. For most organizations, compliance with the guidelines is simply good data security. It’s like calling any internet security expensive and unnecessary.

2. Doctors can share data. They have tools to share it in their EMRs, and there are no restrictions to sharing it with other healthcare providers during the course of care.

3. The security and privacy rules are almost entirely about the preventive of public, accidental, or unauthorized disclosure, and also about giving patients access whatever data you hold on them.

4. Why would newspapers want to publish random people’s healthcare information? Unless it was part of a piece targeting a famous/influential person or medical practice, in which case yes, if they access and publish individuals’ healthcare information without consent, that’s a breach of privacy that can be challenged in court. The law isn’t about the damages per se, it’s about the breach of privacy and confidentially.

The React Named Children Pattern
Adding an additional comment here, as I'm thinking to myself about how I'd clarify the issue further.

Suppose we write a program in `C` which requires 32 bit array, sets an input state, operates on the array, and produces an output state. This program is the logical model, here requiring say 32bits and 10 operations/bit average. So we have 320 logical changes to the array (which btw, wont be purely parallel or serial).

Suppose the most efficient CPU we have requires E_thermo energy for this whole process (setting the 32bit input, operating, reading the output).

Now, using somewhat disputed ideas about physical limits, E_thermo say implies we've used 320,000 'bits' thermodynamically, ie., somehow the CPU has produced an equivalent of 320,000 "energetic changes".

So the CPU has an efficiency, in some suspicious sense, of 100,000 thermo-bits / logical-bit. For each single on-average change to the array we see in the `C program`, we theoretically measure an equivalent heat of 100,000 changes.

Now, how efficient is the brain at computation? Well since we have no logical model of the computation its performing, there's absolutely no way of answering that question.

So why do people say it's efficient? Well because any apparently equivalent algorithm we come up with (in, eg., `C`) to do even basic things that the brain does, requires vast amounts more energy. Eg., processing images on a GPU requires, say 300 W, and our whole brain uses (a claimed) 20 W.

I think the resolution to this problem is that the brain(-environment-body) system implements computation in a radically different manner than anything like a CPU, GPU, etc. I suspect that computation happens at every scale: molecular, sub-cellular, cellular, neuronal, inter-neuronal, nervous-system, body, body-environment, etc. And across the whole body, and using energy in the environment to maintain state.

However, I find the use of the term "computer" and "computational" mostly just productive of pseudoscience. It is a basically meaningless term that only produces confusion. The only useful area where it helps is when handling logical models of algorithms -- models largely absent from the whole of empirical and theoretical science.
I also use Nextcloud for this. Works pretty good. The only problem I have with it is that there is no automated way to backup your calendar/contacts.
author claims simultaneous neuron activation is limited by the 20W power.

Begging the question isn't usually used like this these days, even if it did originate thus. The English language is used the way English speakers use it; yes, even that is quite circular, because there is no formal academy setting down rules that everyone agrees on. Institutions only teach stylistic choices. We use beg the question in exactly the way you say we shouldn't far more often than not to the point that its history is merely a bit of trivia, at least to most American English speakers; Oxford has yet to catch up, but I can't imagine the English situation is that much different than the American one.

Your metaphor is equally bad.

By that logic business class should be banned because business class customers get preferential access compared to economy customers and they use more energy.

According to The Fine Manual: watch --color (-c for short) , should render color correctly,
eg.

watch --color ls --color

but

watch --color curl -s v2.wttr.in

doesn't quite play ball.

In the end I went with something like your solution. I didn't need to put the sleep 60 as the first operation though.

#!/bin/bash
while true; do
clear
curl -s v2.wttr.in
sleep 100

> Before 0.25 the engine was mainly used as framework backed by the scene editor. Now the situation has changed, now it is possible to run your game in the editor, like in many other mainstream engine such as Unreal Engine, Unity, Godot, etc.

"That at the very least adds depth" would suggest otherwise.

And if it's not what I managed to communicate effectively, I can assure you it is not at all my intended meaning.

Which would then falisify your own premise.
I think a single E core can handle all the background processes when they're not doing any real work. I currently have around 250 processes and 3500 threads running on my computer, and the CPU utilization is 1%. It would probably make sense to use an extremely power efficient core that's only used for background services, one core that could be clocked much higher than all the rest for the foreground thread(s), and maybe some combination of E and P cores for the rest of the threads doing actual calculations. But adding lots of simple E cores for parallel work feels a bit like Larrabee.

It's clear that we need something in between regular quad core CPUs, and GPUs connected through PCIe. Some kind of parallel compute unit should be standard in pretty much all CPUs (or SoCs) eventually.
> Never happened. What happened is that the US voluntarily shutdown their oil production out of concerns for the environment.

Personally, I'd prefer to just pay tiny constant monthly fees for things, than to have the mental overhead of knowing there is a nonzero cost for every search I do.

I am prone to microoptimizing things, and I would absolutely spend an objectively excessive amount of time and mental energy trying to avoid doing another search to save three cents.
Why would you cut yourself off? What difference does if make if a human made something or a synthetic? It's not even as if they would be aliens with strange motivations, synthetic would be born/created on earth an instilled with the same values as anyone else.
>Machine AI wouldn't be bound by Theory-Of-Evolution-By-Natural-Selection-In-A-Million-Year.

Yes, but now compare how much time needs a person to leran to recognize a new object vs how much time you need to train a neural network for the same task. You see there is still a problem there, you can't just assume that an AI will be quicker at improving than a human

>, I've found myself paying for OpenAI's GPT-3 playground app in micropayments format.

Unless I'm misunderstanding OpenAI's pricing format for "bulk tokens" [1] prepaid for by credit-cards, this isn't web micropayments in the way many others think of that term. Likewise, buying audiobooks via Audible Credits by prepaying $229.50 to get 24 credits isn't really micropayments.

Some were hoping for internet micropayments at the granularity of transactions rather than pre-paying a large upfront amount to be parceled out in smaller amounts later. What prevents micropayments at the fine granularity is the high VISA/Mastercard credit-card transaction fees.

E.g. many want to micropay 2 cents for a news article without prepaying $10/month or $120/year to a "media aggregator" taking a percentage cut of that.

I have the same issue. If I'm paying 0.005$ for every search, I would stop searching because of the mental effort to optimize everything.

One alternative that could work, is to make a subscription service, and then reimburse the unused amount.

Like make people pay 20$/month, then do your micropayment system in the background, by the end of the month, refund them to difference if they didn't exceed that monthly value.

It creates a positive feeling instead of a constant background stress with every interaction.

When I forgot an iPhone charger plug (not in USA)
And I had that environment friendly “only cable - no plug” USB type C cable (most other phones have plugs with Type A receptacles on their chargers).

Not one charger plug among many other phones in my entire household (including so many relatives attending the two weddings) could accommodate that cable’s Type C plug connector. I somehow managed to keep my phone charged, through two marriage ceremonies in a still-very-rural village in India, by inserting the type C connector of Apple’s brave charging cable in those phones’ type C ports and slow-charging my iPhone which for some reason would always stop at 69% no matter which phone I’m drawing power from.
Being a public ledger doesn't mean your real world identity is automatically connected to a crypto address. In practice most people aren't diligent enough to separate the two, but it's possible.

And then you have private ledgers like Monero.
Yeah, have this in my backlog
It's a nice exercise but doesn't this ultimately proof that using these formalized proofs is flawed? That this system can be made to 'proof' anything, as long as the premises are logical by themself?

Or am I reading too much in the mathematical term 'proof'? Because it sounds more like 'verifiable reasoning' to me.
I'm well aware.

In this case, I tend to strongly prefer the prescriptivist view to the prescriptivist, and misuse generates confusion rather than clarity.

"Enormity", "disinterested", and "very unique" are others on my list.
Your very valid points are - in my reading - addressed in this paper, albeit in a milder and more forgiving form, in the Results section under A Baseline for Maximally Efficient Computation.
A simplistic model relates physics to neuroscience.

Especially:
That is, physics looks at each computational element only as a solitary individual, performing but a single operation. There is no consideration that each neuron participates in a large network or even that a logical gate must communicate its inference in a digital computer in a timely manner. Unlike idealized physics, Nature cannot afford to ignore the energy requirements arising from communication and time constraints that are fundamental network considerations (43) and fundamental to survival itself (especially time) (18, 19).

I wouldn't call it outright pseudo-science as the authors are trying to impose some limited working framework with very technical meanings of "communication" and "computation" in this context. I too, find this "physics"/"cs" excursion very basic and questionable which kind of points to the purpose of that paper: demonstrating an exercise. And as a general symptom the difficulty to overcome the shallow waters of interdisciplinary fields/approaches.

[From my own experience in talking with biologists only after awhile I begin to appreciate the deep complexities of biological/biochemical systems, only to - after some time has passed - forget those subtleties again.
I'm so used to simplify from my physics background that it is actually quite hard to recognize important distinctions in different (more complex) fields which can lead to vastly different mathematical models.]
This doesn't seem correct. What if, for example, the long-running tasks would like to allocate memory, and they cannot because the user has clicked the button a few billion times? In that case, it seems like perhaps we should have accepted fewer jobs, so that we would be able to perform the ones we accepted.
If we assume the horse is a perfect sphere...
If it is smarter than humans it will figure out things that humans can not in shorter amount of time including how to improve itself, no?
