Comment Re:Combining different GNSS systems is also an opt (Score 1) 45

Add acceleration sensors to the equation, they are really precise today. Those things can navigate for a certain range without any satellite signal. The other thing that cars sometimes do, is measuring the distance and they also know about the direction the cars go from the steering angle.

Numerous very experienced people have correlated a great number of the so called "drone" sightings with the ADSB tracks of legitimate aircraft and not one shred of evidence has been presented that these "sightings" are actually drones operated by Russia or other bad actors.

Why would you think this is about Russia? This is about anyone who flys drones close to Airports without explicit permission. And yes, anyone doing that is by definition a bad actor.

Python has built-in support for arbitrary precision integers by default, with no 3rd party libraries needed.

In Python, you can precisely calculate 100 factorial with a default installation. You can't do that with C++, Java, or Rust.

I can do that with my 1989 HP48SX . For arbitrary precision I have to use an additional library though.

Comment Re:No Maxwell's Demons [Re:No stable equilibrium] (Score 1) 59

Sorry, I don't have time to critique people who have alternative theories of physics; there's too many of them out there, and I've noticed that people who think they've invented new physics come up with newly revised theories faster than you can point of the flaws in their previous ones.

For the thermodynamics of adiabatic lapse in atmospheres, try, say, https://duckduckgo.com/?q=ther...

Thanks for your answer, its an answer I heard too often to complain about you.

Just note, that it is exactly this adiabatic lapse that confused me 30 years ago, and after investigating, I found no reasonable explanation in current science. In fact I found relevant issues in Boltzmanns "Vorlesungen über Gastheorie", and I found people who experimentally showed that this law is not universable applicable. I am aware of the term "alternative truth", but in that case, I would just say that it is the second law, that science handles like a religion of galileos times.

Gas in a gravitational field does not violate the second law of thermodynamics. If you drop down in a gravitational potential well, you release energy.

Thats what I am questioning. In fact I have written a short article because to explain the situation that can be found at https://azouhr.github.io/2ndla... .

Basically, whenever a particle is flying down (randomly) it increases speed and becomes warmer, and when rising, the speed is reduced and it becomes colder. This is exactly what you see in Atmospheres, where external radiation is not too high to change the behavior.

I would be more than happy if you were able to show me the error in that thoughts, however I also learned in the meantime, that Joseph Loschmid found the behavior in 1875 (yes, that is 19th century) and was at least partially confirmed by Maxwell. Since 150 years, science has not been able to find an error in what Loschmid postulated. Therefore even thought I came to the same conclusion, I am by far not the first person to find this.

the idea that our universe will end in heat death has escaped the dull, technical world of academic textbooks.... And yet it could be badly wrong. If dark energy weakens all the way to zero, the universe may, at some point, stop expanding.

"Heat death" is a thermodynamic concept, not a cosmological concept. It occurs because energy dissipates to maximize entropy. If the universe stops expanding it does not prevent heat death from happening: when stars burn up their fuel they stop glowing whether or not the universe is expanding.

Actually this thermodynamic concept is just an assumption that cannot be challenged by scientists without loosing all their reputation. It is not accurate however, because if you manage to macroscopic sort the particles into high and low entropy particles, you can gain exergetic energy from a single energy pool.

This sorting is automatically true for example for any atmosphere (read gas in a gravitational field), and thus the whole idea of heat death is based on wrong assumptions.

It should be kind of easy to create even an early warning system as well as evidence on who did what by just listening to acoustics in the sea. I suppose, that those ships will let down their anchor not so long before the cable -- which creates some noise. But then, they will not stop their engine, and instead thrust forward in order to create the damage. Means, when a ship lowers the anchor but does not stop the engine, you could already send your troops...

Just because Deppenapostroph was simply translated as idiot's apostrophe: In German, you have both, Depp, and Idiot. However Depp is kind of a vile version of Idiot. So, you are not just an idiot, but a stupid one. The meaning is not just by chance used on this topic.

So, regardless what some "authorities" say, this apostrophe will always tell something about yourself if you use it.

Submission + - Ask Slashdot: Gravitation: A Challenge to the Second Law (hawking.org.uk)

azouhr writes: The cosmologist, Sir Arthur Eddington (1882-1944), once said, 'Don't worry if your theory doesn't agree with the observations, because they are probably wrong. But if your theory disagrees with the Second Law of Thermodynamics, it is in bad trouble.'

So, I find myself in bad trouble, since I believe to have found wrong assumptions to the second law of thermodynamics, and built a counterexample to that law. Unfortunately, it seems, that there is no expert available that can explain the basics of the second law with respect to that counterexample, at least I could not find any in several years.

The flaw can be found when reading into the Theory by Ludwig Boltzmann, when he states, that molecules fly in straight lines, except when colliding with other molecules or some wall. However this completely ignores the effect of Gravitation. I believe, that I can proove, that
  1. An adiabatic temperature distribution will built up with gases in a gravitational field, even without external heat source
  2. That temperature distribution can be used to gain mechanical energy.

Creating an energy distribution from a single temperature requires energy flow from cold to warm, which is forbidden in the second law.

I have written down the details in an article (too long for here, but still just a few pages) that can be found at: https://azouhr.github.io/2ndla...

Feel free to tear down that article, but please give a good reason.

A similar trick is used by SUSE for SLE and OpenSUSE to avoid the latter receiving extended support which rivals SLE by reincorporating too many of the former's patches into the latter.

You are probably unaware, that openSUSE Leap 15.5 is binary identical to SLES15 SP5. SUSE makes it really easy to evaluate SLES by giving the customers openSUSE Leap, and allowing them to switch to the supported variant later on, even without reinstall.

The only thing you should be aware off is, that not all packages in openSUSE Leap are available or supported from SLES.
