Just to play devil's advocate. There was recently an unverified report that some inverters contained an undocumented cellular modem. If true, it could, in theory, allow for remote modification or control, even when fully "offline" as far as the client was concerned. Basically a mobile phone based back door.

The solution is better verification, rather than bans however. Grid scale devices should have the hardware randomly audited. The software should also be audited and check summed. This would be burdensome at domestic levels, but seems reasonable at grid levels.

I personally suspect the crash in solar panel prices is a result of them deciding to get on with fixing the problem. Basically turn it from a political problem to an economic one.

They are also pushing hard for both modern nuclear fission and nuclear fusion power. Once they start coming online in bulk, their CO2 output will likely plummet.

That's common in the UK as well, though mostly in the cheaper supermarkets. A lot of places rely on the honour system, and convenient drop off places.

I'm of the mindset that you can judge a society quite well by how they deal with shopping trollies.

I've noticed that people often put in near minimum acceptable effort to go optional tasks. The trick seems to be to make the easiest "acceptable" solution, to be an acceptable one.

Shopping carts are another example. The perfect solution is for people to return them to the front of the store. But that's too much effort for many. They leave them wherever they can dump it. An acceptable one is to return them to collection points. It's not optimal, but it's better, and most people will actually do it.

Perfect is the enemy of good.

I suspect paradox are just taking a fuck you attitude here, but that's a separate point.

Like it or not, Linux is a very small part of the gaming ecosystem. We also now have proton, that makes it far less of an issue.

Give all this, I would rather a reliable windows version, with an eye towards not fucking over the proton translation. Any Linux version would likely lack a lot of bug testing etc.

The goal is a stable fast game that runs on Linux. How that is achieved is almost irrelevant. At this point, asking them to play nice with our translation layer is the best option.

I suspect that would be too close. You need a light year of lead to stop 50% of neutrinos. That makes distance the only real shielding. I'd guess 10AU should be enough to push the dose down to reasonable levels. About the distance from the sun to Saturn. If we put the oven in Saturn orbit, that could work. We would need to evacuate that side of the solar system, but that's not too hard.

The real challenge is getting your steak to the table in a timely manner. A relativistic missile could work. Unfortunately the exhaust of earth approach would be a hassle to deal with. The G forces also won't likely do your dinner any good.

Neutrinos can interact with my quarks (and so the nucleus) and electrons. The energy transferred however is very small. Supernova neutrinos are at around 10-12MeV. A photon with the same energy would be around 0.1mm wavelength, or 2.9Ghz. For comparison, you need a wavelength of around 120nm (2500Thz) to crack DNA. This is in the UV band.

In short, neutrinos would damage via thermal effects. There would be effectively no shielding by other tissue, leading to near perfectly even heating. Your spaceship will also be kicked by the force. However, it would be evenly spread over every atom present. You wouldn't experience any g forces, just the feeling of being cooked alive, perfectly evenly. An external observer would see you get pushed back.

I'm now wondering on the kitchen utility of a neutrino microwave. It would deliver perfectly even cooking, unlike an oven, or microwave oven... The safety shielding and power requirements would likely be non-viable, however.

No, we are perfectly fine at reading. We just don't accept the bullshit excuses as cover anymore.

Unfortunately there are too many people who dog whistle online. When they are called out, they claim they were sarcastic or trolling and "why can't you take a joke?". It can make many of us quite reactive to it.

Given how much of today's political hell grew out of "jokes", it's akin to walking into a veteran's PTSD support group and firing off a cap gun. There are grounds where it could be a funny prank, but it's 100% on you to not cross the line.

Faster, with more power is better. You will almost always get discolouration however.

The goal is to vaporise the paper before the heat can spread to the edge and discolor or ignite the rest of the paper.

Basically, get your machine moving as fast as possible, without skipping etc. Then adjust the power to a bit above the 'just cut' power. You also want to make sure your focus is as good as possible, and your paper is as flat as possible. Good suction also helps remove the debris before it can spread the heat or defocus the beam.

Also check your alignment. The unfocused laser beam is remarkably wide. If any light is not on the proper path it can deflect weirdly. This creates secondary spots just of the main one. These normally don't matter much, since they lack the power to melt acrylic etc. The can be strong enough to discolor paper however. You want the beam to hit the lense dead center at 90 degrees. Paper allows very little margin of error. Make sure your mirrors and lens are clean and unclouded. These can create the side scatter I mentioned.

I've not used it on card, but masking tape on the cut lines helps a LOT with plywood. The discoloration is ejected material falling back down. The masking tape catches it and can be peeled off later. Depending on your card and design, this could work.

Hope that data dump helps.

I ran the numbers extending this. It would be 500,000km, or 0.004AU to vaporise meat. This is well inside the star, possibly within the core itself (making the maths even less reliable).

This is countered by the fact that neutrinos almost never interact with normal matter.

Based on the xkcd discussion posted, you would get a 4 severts dose (lethal radiation) at around 2.3AU. About the orbit of Mars. This is radiation damage however. You likely wouldn't feel it directly, let alone be vaporised. This is also already inside the star going supernova.

To vaporise meat takes about 1500000j/kg. This would equate to 1,500,000 severts. Assuming a point emitter, this would be with 0.004AU, or about 500,000km away. This is likely well within the core of the star, so the maths likely breaks down before this point.

Both can get expensive, at least for some. If your needing to flush it every couple of hours then £/$5 a bottle gets expensive.

It's better for people to have an easy option given, than have them figure "I can get away with tap water" can make it worse.

It depends on the reliability.

If you announce it, there are often counter measures to the counter measures. Once the enemy knows, the reliability begins to degrade. E.g. mirror finishes can disperse laser strikes, jinking can doge orbital rail guns, or dummy submunitions can overwhelm interceptor shields. Yes, these can be countered in turn, but you now have a new technological arms race.

There's also the first strike problem. If you are going to be invulnerable, then a first strike might be reasonable, before the system comes online. This was actually part of the reason the "Slam" project was stopped (a viable, but utterly batshit insane weapon system). They were worried that if the USSR got wind of it, they might decide a first strike, before it came online, was the only reasonable response.

It could be argued that the government "owns" the whole country. It gives you unlimited use, for a 1 time fee. The existence of property laws, property taxes, and eminent domain implying this.

It depends on how pedantic the vampire is about it.

I still don't get why "rich lists" aren't done using tax returns. It's a clear yardstick to compare egos by.

It also has the side effect of encouraging civic contribution via taxes. By the time you're that rich, money is just a score. Make it worthwhile not to dodge taxes, and tax dodging will drop off.

If someone is attempting to drop turds on you, from 20 floors up, you've REALLY pissed someone off. That takes dedication and ingenious planning to pull off.

Congratulations on your arch nemesis!

Can you imagine the reverse? A "female tears" mug, being used to mock a woman after domestic abuse. It would have caused an unbelievable amount of outrage! The fact that the situation has deteriorated enough that I'm not sure it still would, shows the flaw in the mentality.

Was lunch included?

Sucking up to the oppressor. Stockholm syndrome is an extreme example. It prioritises long term survival over freedom.

Basically, be nice to the bastard aggressive boss, and hopefully he won't fire you for looking at him funny.
