Also why the seemingly arbitrary graduations, 24 hours, 60 minutes, 60 seconds. If it was say 10 hours in a day, 100 minutes in an hour, 100 seconds in a minute, seconds would be close to the same amount of time. Same with latitude and longitude, why 360 degrees in a circle with 60 minutes in a degree and 60 seconds in a minute.

CO meter for sure, but a CO2 meter? It’s actually a good idea to have CO alarms in your house if using natural gas powered appliances. However CO2 is only a concern if you’re in a hermetically sealed environment like a submarine or space ship. I suppose it could be useful to check proper ventilation in the home, but normally you can just open a window.

Anyway the Earth has a carbon cycle, in other words it filters natural CO2 emissions through environmental processes. The problem is the amount added by industry is more than the natural carbon cycle can process. So levels are steadily increasing.

When we talk about zero carbon footprint we mean sources from industry like driving gasoline powered cars, generation of electricity, and production of consumer goods. A good amount already comes from natural processes like volcanos and erosion so we don’t actually need a zero carbon footprint, just need it low enough to avoid overwhelming the natural cycle.

At a personal level it would be just about impossible to have a zero carbon footprint. If you had a solar and wind powered home off-grid and used it to charge an electric car you could be well below average. However any consumer goods you use put carbon in the air to produce them. Even if you went full native you’d still be putting carbon in the air burning wood and candles.

Lemm.ee best instance, lemmy.world worst instance.

It doesn’t matter how many communities an instance hosts since you can interact with any community on any instance (barring any defederation). Lemm.ee’s strength is in being a fast, reliable instance with the best admin.

It’s pretty ironic how companies will spend so much money on advertising to gain brand recognition, but then throw it away on a whim.

Do each app need to manually integrate with another app to be considered federated or is any app using ActivityPub automatically integrated to your app?

ActivityPub provides the framework, but a platform also has to be designed to support another platform. It’s not automatic.

Good to see the FCC going after this kind of thing. Put them in jail even better.

I have my phone set up so the only numbers that chime the phone are those in my contact list. The abuse of voice and text on the cell network is rampant and it’s equivalent to trespassing.

I have on old car. I should replace it, but it doesn’t have a lot of mileage. I’m honestly dreading the purchase of new car because of this practice, not just the subscription features, but the control the maker has by being networked to it. I love my old dumb car.

Can always tell when a show is 4:3 aspect. Recently I’ve noticed some modern TV shows adopting the theater aspects of flat (1.85:1) or scope (2.4:1) which I think is pretty cool. The last episode of Strange New Worlds I watched was in scope, that’s some high end filming.

I’ve been using LED bulbs for a good number of years, I’ve only had one or two die on me. The longevity alone makes them much better than incandescent, but then they use a tenth the power.

My favorite is the A15 Edison style. That’s the appliance size, smaller than the standard A19. The A15 fits in everything so I only need to stock one size.

I would say this is likely not a practical super conductor… But it may well be the first ever room temperature super conductor.

Yes of course it would be a big deal if they create one to begin with. However if it’s difficult and expensive to produce, that’s not much help. It has to be mass producible and inexpensive to have industrial significance. I mean we already have expensive solutions. Don’t need any more of those.

The first semi-conductors were not practical either, but we can all see where that led!

I don’t know that semiconductors are a good parallel. Growing the crystals dates back to the early 1900s and was never an expensive or technologically difficult process. Doping silicon to create devices like diodes and transistors was something new, but was not exceedingly expensive or a great technological challenge. The migration to chips which require lithographic doping was more of a challenge.

In any case semiconductor devices were practical shortly after development. One of the first consumer products that used them was the “transistor radio” which was inexpensive and came out shortly after invention of the technology.

A practical superconductor is a huge deal, it would drastically change the way we deal with electrical power distribution and electromechanical applications. So any development is going to be big news. Though we’re not talking about an actual working conductor, it’s just excitement over research advancement, yeah? I’ve seen this kind of “big news” before in other tech sectors and time often proves it unworthy. If it does present a big step toward a practical superconductor that’s great, but I wouldn’t count any eggs yet.

Dogs were instrumental in early human survival and they’ve benefited for it. There’s almost a billion dogs in the world, but only a quarter million wolves. So in a natural selective sense that was a good move wolves made by becoming companions with humans.

Behavior has been bred into dogs going way back to the beginning. Fetch is one of those behaviors. I recently watched a documentary that showed the unique interaction of dogs with humans. Dogs are really good at understanding human body language. For example you can point at something and a dog will cue on it. No other animals reliably respond to that gesture, even chimpanzees which are genetically closest to us.

I’ve already seen many commercials using what is clearly AI generated art and voices

I’ve been noticing that as well, freaky.

Would this potential superconductor work in devices like phones and laptops? Would it lead to more efficient operation?

If inexpensive it could be used in power components for consumer electronics like phones and laptops, but wouldn’t make a huge difference since most of the power consumption occurs in chips and displays where superconductors wouldn’t apply. Though it could lead to some reduction in size and better efficiency. Battery operated devices are considered low power. High power applications are where superconductors offer the most benefit.

Yeah nobody is all bad, even Reddit.

That’s good they won’t be adopting WEI, but if my bank or some other critical site decides to enforce a desktop browser with it, I’m still in the same boat. I did think of a way to avoid a WEI browser on my desktop if it comes to that. I can probably substitute a phone app for any critical services, but that’s still a drag. I don’t like phone apps much, I use a desktop browser for everything.

I think Google’s destruction of the Internet is most simply a matter of influence. If Chrome didn’t have the huge market share they wouldn’t be able to pull off this kind of thing, open source or not. Unfortunately people have a herd mentality with everything on the internet so we allowed it to happen by doing what we always do.

A conductor with no resistance is a big deal for many electrical applications. Electrical resistance is often a big part of design. Removing that aspect changes things significantly. Electrical power losses and the size of conductors can be greatly reduced.

I’ve read lots of unsubstantiated claims about superconductors. A solution has to be producible in quantity at a reasonable cost. Otherwise it’s not going to be a breakthrough. I mean we currently have expensive and bulky superconductor solutions, but they’re limited to applications where it’s reasonable such as MRI machines and particle accelerators.

An inexpensive room temperature superconductor would make the most difference in tech sectors such as power transmission, electromechanical, and power electronics. These are areas where power loss due to circuit resistance is a big part of design. The impact would be minimal for computing and logic. There may be areas where power loss can be reduced, but logic relies on semi-conductors which must have resistance to function, it’s in the name. The term “semi” implies resistance.

Here’s something more interesting. A matter-antimatter reactor converts 100% of mass to energy so it’s a hundred times more efficient than fusion. In modern times antimatter has been produced at quantum levels in large accelerators such as the Hadrian collider. So it does in fact exist and can be produced.

However a matter-antimatter reactor has some serious technical problems. For one it’s currently impossible to create antimatter in any practical quantity. Second if antimatter comes in contact with matter, instant boom. Like a sugar cube size of the stuff could level a large city. So containment would be an insurmountable problem.

The interesting part is when you see an antimatter reactor in shows like Star Trek, it’s based on real science. Interestingly in 1968 when they wrote the original Star Trek, nobody knew antimatter was a physically real thing. That’s a case of sci-fi predicting science.

Fusion and fission are quite different. A practical fusion reactor does not exist. It’s outside our technological capability right now. Current fusion reactors are only experimental and can not maintain a reaction more than a small fraction of a second. The problem is plasma containment. If that can be solved, it would be possible to build a practical fusion reactor.

The fuel for a working fusion reactor would likely be deuterium/tritium which is in effect unlimited since it can be extracted from seawater. Also the amount of fuel required is small because of the enormous amounts of energy produced in converting mass to energy. Fusion converts about 1% of mass to energy. Output would be that converted mass times the speed of light squared which is a very, very large number, in the neighborhood of consumed fuel mass times 10¹⁵.

Fusion is far less toxic to to the environment. With deuterium/tritium fusion the waste product is helium. All of the particle radiation comes from neutrons which only require shielding. Once the kinetic energy of the particles is absorbed, it’s gone. There’s no fissile waste that lingers for some half life.

I can have trouble sleeping and have to battle fatigue at times. Not long ago I crunched the bumper of my car into the side of the garage because I was too mentally fatigued to drive. Didn’t do a lot of damage, scratched the bumper and did minor damage to the the wall, but something I would have never done if I was properly rested and alert. Mental fatigue is a strange thing, it can make you fail in performing simple tasks you do routinely.
