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.

Big difference is a modern sailboat like a ketch or sloop can maintain a straight course as much as 45 degrees into the wind. A Victorian era square rigger is greatly more limited with a range about 60 degrees off either side of downwind. A kite would be even more limited, probably within 45 degrees so it would only be useful when going mostly downwind. Still if it's cheap and easy to deploy it's free energy when it can be used. An interesting parallel is the spinnaker sail used on a typical sailboat flies much like a kite and can only be used within a similar downwind range. It's a very powerful sail when it can be deployed.

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.

Yes female action heroes are a trope now. They've over-played it, but of course anything from Marvel or DC is going to be shit. These days they're just movie mills pumping out the same old rehash.

The Alien movies made a female action hero seem natural. They did it right. There's been a few others that have done it right. More have done it wrong.

I don't know anything about the Barbie move since I haven't seen it. I would like to see it but will wait until it comes to streaming. My wife saw it with a group of her friends and said it was cute and weird, but definitely worth the watch. So evidently it's not in the same caliber as Legally Blonde.

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.

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 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.

Microsoft’s name was basically equivalent to dogshit from the mid-90s until maybe the mid 2000s.

I'm old enough to remember well the Microsoft hate. It's not so much they've changed their ways, but Google has now taken the trident and diverted attention away from them.

 

I thought this was an interesting take on what's happening in modern film.
