I would also add that usually i will be used inside the code block to index locations within whatever data structures need to be accessed. Keeping track of how many times the loop has run has more utility than just making sure something is repeated 10 times.

I only used it for desktop applications. That’s good to know.

Screen sharing in signal seems to work reasonably well.

Helion is a completely different technology vs tokamaks which is what you’re thinking of. They pulse the plasma to create brief bursts of pressure/heating/fusion. They do already have their seventh prototype machine operational so while we can’t independently verify their claims, it’s probably not all bluster.

I have mixed feelings about their approach. They plan to use a deuterium and helium-3 fuel blend. That has a couple major advantages. Most of the reactions will be aneutronic and the energy is released in the form of highly energetic alpha particles and protons. The lack of a high energy neutron is a huge advantage for safety and longevity of a reactor. High energy neutrons are hard to shield from and they cause most materials to get brittle and weaken. Netrons are not good for personnel to be around and they can leave some materials radiactive making reactor maintenance/disposal costly. The other advantage is that since all the energy is released as kinetic energy in charged particles, they don’t have to try to absorb high energy photons or neutrons into a water blanket to drive a steam turbine. Instead, the kinetic energy results in an electromagnetic pulse that can be harvested by the same magnets that constrict the plasma to begin with.

Sounds amazaing, right? So why doesn’t everyone use this approach? Helium is rare, but Helium-3 is especially rare, making up only about 20 parts per million of helium found in geologic deposits. So simply put, it is currently infeasible to use Helium-3 at scale. Helium-3 can be collected as a byproduct of breeding tritium for use in nuclear warheads. Enough helium-3 is produced for some demonstration reactors, but any real amount of demand will quickly outpace what the DOE produces.

Helion plans on breeding their own Helium-3 in Deuterium-Deuterium reactors they will operate. However D-D reactions are not aneutronic. So all the materials lifespan/shielding/ maintenance nightmares that come with operating a nuclear reactor will still apply. That means operators will have to buy very expensive fuel from Helion indefinitely. Helion doesn’t exactly deny this drawback, but I really dislike how much they gloss over it in their public communications.

Here’s a video tour of their test facilities that explains the basics of their approach. https://youtu.be/_bDXXWQxK38

I’m inclined to think they’ve demonstrated enough results that they are likely to be able to build a working unit quickly, however, that would still be a long way off from creating any sort of sustainable supply chain that would be a viable option for anyone beside datacenters.

Additionally, generate a downloadable pdf or similar with qr code containing whatever info needed to verify the ticket.

Natural Intelligence has already proposed solutions. The real lie is in expecting us to believe that decision makers would be any more likely to act on the solutions that AI comes up with.

The shape they chose for the frame is a Möbius strip, which has the primary defining characteristic of having only one side and one edge. If you pick a row of keys to follow, after one loop around, you’ll be on the underside of the frame. Continue to go around another full turn and you’ll be right where you started. So both sides are actually just 1 side that loops around with a half turn of twist. A similar math curiosity would be the klein bottle, which has a single surface.

It’s one-sided…

Well the context was a concern about a defamation suit resulting from this post. If the company never found this post then the anonymity of the poster is irrelevant anyway. The company could easily tell who made this post based on the timing of their already existing email correspondance seeing as this is clearly not a request they receive often.

That’s flawed logic. The company would pretty easily know who has been emailing to request the source code for that specific tool in the timeline just before this post. The lemmy profile may be anonymous, but I doubt OP’s emails were.

No, never. Current charging rates already get close to thermal constraints. Hitting those charging rates either requires accepting much lower power density or using way more metal per cell. This research might inform design changes to improve charging rates, but we’ll never see high capacity batteries charging in a minute.

The researchers know this and only mention wearables and iot devices applications. The article author erroneously makes the leap to high energy density devices.

If you don’t care about energy density at all, ceramic capacitors can already charge and discharge in microseconds.

A bear has time and motivation to keep trying over and over again to get into the garbage. People are generally much less determined to figure it out.

Then you find out that while the new place doesn’t have the problems the old place had, it has a whole new set of problems.

Sometimes the devil you know is better than the devil you don’t.

Recent anecdotal evidence shows that elections are not particularly effective at selecting against incompetence.

Error correction relies on the majority of values to remain unchanged. I don’t think that assumption holds for qubits at room temperature. I’ll admit that I’m not well read enough to be certain.

Room temperature superconductors would be great for a lot of applications, but I don’t think they do that much to enable quantum computing.

Afaik superconducting quantum computers are operated well below the critical temperature for copper. They wouldn’t go through that extra effort if it wasn’t necessary.

At the temps needed, regular copper is superconducting.

It could be helpful in some of the intermediary stages to reduce heat production, but it’s not going to be a major linchpin for quantum computing. They’ll still need cryostats and liquid helium cooling.

Quantum computing needs to be cold to avoid thermal noise from destroying coherence. A room temperature superconductor probably doesn’t enable room temperature quantum computing.
