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.

Agriculture is also frequently exempted from overtime pay.

You might end up in a sticky situation.

You’re only making money if you downsize, move somewhere cheaper, or switch back to renting. If you move and all the other houses have gone up, then you just end up having to sink any gained equity into affording your new place. Rising prices really only help developers, realtors, and REIT’s.

I’ve received more healthcare provider PII leak letters in the last couple years than the number of appointments I’ve had. Everyone is so eager to come up with some shiny new software to sell in the healthcare goldrush, but so many of them are absolutely terrible at security.

nhc.noaa.gov is the best for quick, up to date official info about expected impacts. Also local county and municipality pages are important to check for evacuation orders and routes.

For anyone who wants technical deep dives into the meteorology of tropical storms, I can’t recommend www.tropicaltidbits.com enough.

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…

Likely unrelated, but after I’ve cut raw garlic cloves everything feels weird, almost sticky, no matter how much I wash my hands.

That’s $700 for a digital only edition without a disk drive or vertical stand. It’s $810 to match the features of the PS5.0

The headline says worlds first all-electric train rather than worlds first all-battery-powered train. There have been many all-electric trains before. So the headline as written is incorrect.

I’ve had that happen with what i assume was a hand lotion because there was a particular part of the lid that smelled.

I don’t know why other people are treating you with so much disbelief. This absolutely can happen with people not thinking about how their habits impact what customers are consuming. With how many millions of coffee beverages that are served every day, it shouldn’t surprise anyone that some small portion are handled improperly with poor hygiene. It also shouldn’t be overly surprising if you’ve had it happen multiple times because you likely visit the shops near you. Such an event isn’t random and is the result of someone’s bad habits.

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.

Because the way you probably raise your foot toward you when putting on your socks ends up with that spot pointing toward your eyes.

As to how that helps before you’ve actually got the sock on, you’ll have to ask the designer.

Remapping gpio pins doesn’t require changing wiring, but it might require tracking a unique firmware revision.
