No such thing. Ask away!

!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.

The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:

Rules (interactive)


Rule 1- All posts must be legitimate questions. All post titles must include a question.

All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.



Rule 2- Your question subject cannot be illegal or NSFW material.

Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.



Rule 3- Do not seek mental, medical and professional help here.

Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.



Rule 4- No self promotion or upvote-farming of any kind.

That's it.



Rule 5- No baiting or sealioning or promoting an agenda.

Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.



Rule 6- Regarding META posts and joke questions.

Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.

On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.

If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.



Rule 7- You can't intentionally annoy, mock, or harass other members.

If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.

Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.



Rule 8- All comments should try to stay relevant to their parent content.



Rule 9- Reposts from other platforms are not allowed.

Let everyone have their own content.



Rule 10- Majority of bots aren't allowed to participate here.

Because that's the cooling system required to run the thing. It requires more toxic coolant, that will eventually end up in the ocean, than several hundred supercomputer megaclusters and sucks more power than a thousand suburbs.

[–] [email protected] 2 points 4 months ago (1 children)

I believe you may have misread your own source.

For example, the world’s fastest supercomputer, Frontier, draws 8 megawatts when it idles — a quantity that could simultaneously power thousands of homes

If this was the basis for your saying this…

several hundred supercomputer megaclusters and sucks more power than a thousand suburbs.

… then you misread AND misstated.

Misread: this “thousands of homes” energy use was in reference to Frontier, which is not a quantum computer but based on more conventional architecture, the kind the article goes on to say might eventually be improved upon by quantum computing. Eg:

Consequently, experts are looking to new strategies that can rein in energy use while continuing to improve computing performance. One proposed solution: quantum computing.

Misstated: “thousands of homes” != “thousands of suburbs.”

A suburb is not a home but a a collection of homes, a region of a city even. See definition:

an outlying part of a city or town. b. : a smaller community adjacent to or within commuting distance of a city. c. suburbs plural : the residential area on the outskirts of a city or large town.

So in your zeal to make your point you demonized quantum computers, which could be a solution to the problem you’re ostensibly so concerned about, and in the process you misstated a metric by at least one order of magnitude.

So yeah… I don’t know what to tell you. You really messed up here. Your problem is with LLMs and big compute, not necessarily quantum computers.

[–] [email protected] 2 points 4 months ago

Good stuff! I rescind my comment and defer to all your corrections.

[–] [email protected] 1 points 4 months ago (1 children)

I'm prepared to be proven wrong on this, as my exposure to quantum computer cooling systems has been super brief, but as far as I know there are no toxic coolants.

The pre cooler is a Pulse Tube Refrigerator, and the main cooler is a Dilution Refrigerator. Those both use helium, and that stuff floats out into space. I doubt it's going into the ocean. Here's another article that talks about the operation.

Like I said though, my exposure was brief. Unfortunately we didn't land any projects with the supercomputer people 😞. I'm always down to learn more about niche topics though. Makes me super fun at parties. If you have good sources shoot them my way. I couldn't find anything in my 5 ish minutes of web searching.

[–] [email protected] 1 points 4 months ago (1 children)

Wrong. I breathed in some helium once and it made my voice all high pitched which threatened my fragile masculinity. Very toxic.

(/s...)

Never worked much with cryogenics, but the one thing I learned was to never get in an elevator with (large quantities of) liquid nitrogen


if the elevator stops it can displace the oxygen and that's...kinda bad.

[–] [email protected] 1 points 4 months ago (1 children)

Yeah, totes. Scentless non-toxic gases can still be deadly by merit of not being oxygen.

The only recreational octave-shifting gas I indulge in is Sulfur Hexafluoride. Bolsters the ol' baritone.

That's no bueno for the environment.

I just looked it up and...

SF6 has 23,500 times greater global warming potential (GWP) than CO2 as a greenhouse gas (over a 100-year time-frame) but exists in relatively minor concentrations in the atmosphere. Its concentration in Earth's troposphere reached 11.50 parts per trillion (ppt) in October 2023, rising at 0.37 ppt/year.[8] The increase since 1980 is driven in large part by the expanding electric power sector, including fugitive emissions from banks of SF6 gas contained in its medium- and high-voltage switchgear. Uses in magnesium, aluminium, and electronics manufacturing also hastened atmospheric growth.[9] The 1997 Kyoto Protocol, which came into force in 2005, is supposed to limit emissions of this gas. In a somewhat nebulous way it has been included as part of the carbon emission trading scheme. In some countries this has led to the defunction of entire industries.[10]

Umm wtf? Why are we selling this stuff in compressed air cans ? Even methane is "only" 30x more potent than CO2 .

[–] [email protected] 1 points 4 months ago

3M made a great alternative I actually tried to get my company into, Novec 4710... But turns out they've stopped making it.

The bitch about SF6 is that it's so stable (as required, to resist high voltage electric breakdown) that it also lasts way, way long in the atmosphere.

Yeah man, I don't know. I think we need to just use less energy, as a species.

[–] [email protected] 1 points 4 months ago (1 children)

Helium is not toxic and it sure as fuck isn't going in the ocean after it escapes a quantum computer.

[–] [email protected] 1 points 4 months ago (1 children)

It's also one of the most abundant elements in the universe

[–] [email protected] 1 points 4 months ago

But it is difficult to acquire here on earth.

As uranium and thorium naturally decay underground, they produce some helium as well. That’s why you can literally make a helium mine. On earth it’s also a finite resource, because once released into the atmosphere, it will eventually escape the atmosphere and end up in space.

Congrats on getting upvotes for this utter bullshit, none of which is substantiated in the article you linked.

Edit- this was at +15 when I first saw it.

[–] [email protected] 0 points 4 months ago

A quantum computer using current technologies can't scale to that size. Enormous advances over what is now currently possible would be required to get it to that number of qubits, and then the whole issue of cooling can be revisited.

[–] [email protected] 0 points 4 months ago (1 children)

Wow, that is insane! But it's also amazing that it has been able to solve problems that humans haven't been able to solve in over 50 years.

[–] [email protected] -1 points 4 months ago* (last edited 4 months ago) (1 children)

What are you talking about? Most of these things are experimental and none of them have solved a single fucking thing.

[–] [email protected] -1 points 4 months ago (1 children)

From the linked article

In 2020, the artificial intelligence (AI) software AlphaFold demonstrated that it could predict the three-dimensional structure of proteins from their amino acid sequence2, a 50-year old grand challenge in biology.

[–] [email protected] 1 points 4 months ago* (last edited 4 months ago)

They did not say that was achieved with quantum computing

Eta - here is a more suitable quote from the article:

For instance, a 2020 demonstration showed that a quantum computer could perform a math puzzle using 50,000 times less energy than the world’s most powerful supercomputer at the time.
