And VM guests can't break out of the hypervisor... Oh wait, they can, if the hypervisor is buggy.

If the universe is a simulation, it is a pretty complex one. Bugs would be expected.

However, humanity has access to such a infinitesimal fraction of the universe, it would be unexpected to find bugs in simple parts like ours. The bugs would seem more likely in less tested parts of the code, like at extreme energies or very small distances.

Yes, you didn't read the thread. The argument was that the last mile providers who don't implement BCP38 should be blocked from the Internet. Last mile providers can only be blocked by the large backhaul providers, and they are never going to do that.

You don't implement BCP38 and any new DDoS prevention and mitigation standards, you become the first to be blocked upstream

The only ones who can do that are the large backhaul providers. Why would they annoy their customers by enforcing a policy that means they have to move less data? That would be a daft business move.

Even if they document the tests, if they can be gamed in a test representative of "normal usage", then the same gaming will kick in on actual "normal usage", and so the test will not have been gamed.

Normal usage will be viewing a different movie than the one they test with. If you can get viewers to only watch the test signal, over and over, then sure there is no variance between expected use and actual use. However, I did not buy my TV to watch a specific set of video clips in a specific sequence, repeatedly.

Your sound bar would be only using max 20 to 30 Watts, Peak is a useless measure because it is a measure the power the sound bar can pump out for a moment, if you try to drive it hard continuously it will just crap it self and you will very soon find yourself pushing the volume down to a level it can actually handle.

The AC has it right. 180W is marketing. It will never take that from the socket.

My supposedly "smart" Samsung TV detects when power saving activates on the attached device and puts up a bright white logo to inform me. The logo does not go away. At least it moves around, so the wear on the screen is somewhat even.

The only way to do power saving with modern TV's is to use ARC, and ARC support is just not very widespread yet.

But Power Companies, who rely on Energy Usage Tests to forecast demand and allow for it, do care.

You imply that power companies try to guess which items people buy, and how much they use them, and then use the Energy Usage Tests to figure out aggregate demand. This sounds highly improbable.

English politics are strange.

Conservatives and Lib Dems set up a coalition, Conservatives do a lot of bad things and Lib Dems only prevent some of them: Lib Dems collapse.

Conservatives and Labour jointly try to run a campaign to stay in the EU, to deal with the mess that the Conservatives created: Labour collapse.

Comment Re:Bigger but with less thrust? (Score 1) 79

Absolute thrust does not matter all that much, as long as the thrust can actually lift the rocket + payload off the ground. Lower thrust means gentler acceleration which is nicer for cargo but especially for crew, if you want to man-rate one day.

Higher thrust also means you go faster before you escape the atmosphere. This increases maximum aerodynamic load.

F1 is a funny example. F1 tires are deliberately crap; it's part of the contract that the manufacturer isn't allowed to deliver good tires.

If Formula 1 teams could buy any tires they want, the tires would have better grip, work over a wider range of temperatures, and there would be no tire changes during a race. But that would be boring.

For quality tires, look at endurance racing.

Any energy released comes from the chemical reactions which are the bonds between electrons being broken and created.

The reaction products have a mass that is ever so slightly lower than the mass was before the reaction.

A lot of online explanations get this wrong. Like this one: from the BBC, explaining conservation of mass in chemical reactions. It would probably unnecessarily confuse the students who focus on all the mass that a fire "loses" as CO2 and water vapour and such, which is not lost at all.

The mass loss is extremely small of course. For an energy release of 1J, you lose 11 femtogram (1J/c^2). Good luck measuring that on your high school scales, or indeed any scales at all.

That would not work though. Deuterium fusion reactors work by turning mass into energy; they are just not very effective at it. Most of the mass is still there after the fuel has been burned. Using energy from them to produce deuterium would be rathercounter-productive.

(Coal fired power plants turn mass into energy as well, but they are even worse at it).
