drran··on History's deadliest air raid happened in Tokyo during World War II (2020)
They come to that conclusion after the end of the war, by asking Japan officials. We all are smart after a battle. Can you do this trick NOW?

So, nuclear bombing was used to end the war and save lives, but these lives were unnecessary. :-/

So, you see no difference between invading and defending.

If RF will kill millions of Ukrainian with conventional weapons, like they did in 1932-1934, or capture and destroy another major city, like Grozny, it's OK for you. If Ukraine will do the same for RF in return, then it's war crime for you, because victim of conventional weapon ≠ victim of nuclear weapon. Right?

> Thankfully this scenario is highly unlikely.

Two nuclear nations are at war since 2014. Where you live?

Aggressor want to occupy as much land and resources as possible and kill as much opposition as possible.

Defender want to save people lives and protect status quo.

> But the narrative I'm mostly arguing against is not that many welcomed the bombings, but the specific American narrative that there was no other way and that they "saved Japanese lives".

Yep.

> No one wants hostile foreign troops on their border. I see parallels in Ukraine. Russia really doesn't want NATO to encircled them. We would have problems with Russian troops stationed in Toronto.

Ukraine don't want members of Russian Federation and it allies to encircle Ukraine, so we are going to liberate Belarus and take Kuban back. The only important thing for us is what WE want, isn't?

So, if RF will invade Ukraine again and Ukraine will nuke a major city in RF in return, it will be a war crime?

drran··on How Einstein arrived at his theory of general relativity
I agree, that for most calculations those details are unnecessary and can be avoided. However, existence of something is not depended on it necessity for us.

Moreover, AFAIK (I'm not a real scientist, so beware), Higgs «field» and medium for gravitational waves (g-medium?) are two different mediums, because Higgs boson is spin-0 and it gives mass, while graviton is spin-2 and is massless.

drran··on How Einstein arrived at his theory of general relativity
No, they say that arms are expanded and contracted, but this means that measured speed of light must c±delta, while measured speed of light is in c...c-delta range. AFAIK.

Moreover, if arms are just expanded/contracted, i.e. it's density wave, then gravitational waves and light from distant mergers should arrive at the same time ± few milliseconds, while light arrived 1.7 seconds later, i.e. light is slower by 1E-15.

Moreover, somebody told me that density wave is not possible for gravitation, because gravitons should be massless(of course) spin-2 particles. IMHO it a wave of flips or deflections.

See also https://en.wikipedia.org/wiki/Variable_speed_of_light

Anyway, Higgs «field», which gives mass, exists, so a medium, which exists at any point of our Univers, exists, so gravitational waves are waves in a g-medium, which is connected to the Higgs medium somehow, thus, for gravitation, c is speed of gravitation in the medium.

For light, it should be same. I see no reason to say that c is the speed of gravitation in g-medium, while light propagates in pure nothing and c is the top speed in the pure nothing. Nonsense.

I definitely will not use jDeploy on Linux. Downloaded JVM, without disto-specific patches, is useless, because it will hang or segfault.

> Previous comment about SR, although GR is a natural extension of SR for non-inertial reference frames.

Sorry, but SR is a special case of GR now, so not a big deal.

> The interpretation of it is that it proves the constancy of the speed of light. This is the case whether SR is assumed or Lorentz ether theory. The two theories result in identical predictions, except LET assumes the existence of an ether but without any way of detecting it.

Now we have LIGO and Virgo interferometers, which clearly shows that speed of light in pure vacuum is not constant.

Now we know that if we will put an interferometer into space, it will detect deviations in speed of light. (We know it as gravitational lensing).

Now we know that gravitational waves exist and are conducted by a medium (Higgs field/Higgs boson).

Now we know that gravitation is a bit faster than light, so photons are not flying on 100% of C, thus they are not immortal, so they are losing energy with time (Red Shift).

If you say that GR/SR is still valid, despite opposing results from experiments, then those experiments are irrelevant for GR/SR at all. Regardless of what experiment will found, scientists will be able to find a way to explain results in terms of GR. With enough number of constants, a formula can make paintings or generate music after all.

> Michelson-Morley rules out a stationary ether, at least without length contraction which Lorentz added to attempt to repair the theory. Michelson-Gale-Pearson rules out ether drag. SR and LET are compatible with both experiments. Whether or not the ether is real is philosophical quibbling without a method for separating LET from SR.

If we put a sail into a box, to test the existence of a wind, then we may find that there is no wind in the box, if the box is tight enough. It can be interpreted as «there is no wind, so no atmosphere, we are on a Moon», or it can be interpreted as «there is no wind in the box». IMHO, the second variant is valid.

For me, Michelson-Gale-Pearson experiment doesn't rule out drag. Fizeau shows that drag exists, but it works in heavy mediums. Physical vacuum is too lightweight to change the course of photon just by itself. It will work at the scale of the Solar system.

> The Higgs field, just like other fields in quantum field theory, is a relativistic field; its Lagrangian is Lorentz-invariant.

Nobody says that Higgs field is stationary. It expected that it will move and behave like any other field, with currents and gradients of stength. However, the average of Higgs field of our visible Universe can be used as a reference frame. I interpret CMB as light of distant galaxies with z=1000, so it can be used as representation of this average. For example, the Sun moves at a cumulative 369 km/s relative to the Cosmic Microwave Background (CMB) in direction 264°l, 48°b.

drran··on Ask HN: How are ordinary citizens in Ukraine dealing with what’s ahead
After 8 years of war, it's boring. Snow is much more frequent.
drran··on Easily handle CLI operation via Python instead of regular Bash programs
Refactor your terrible and hard to maintain script into a well looking and maintainable script. It's not a bash fault.

My bash-modules[0] project[1] may help you with that. Typically, I perform script refactoring in these steps:

1. Split code into few subroutines with clear boundaries between them, or split a large script into multiple simpler scripts.

2. Add an error handler with transparent message to every line of code.

3. Add command line options to override hard-coded things, to be able to test things in isolation.

4. Write documentation (man-page) for script, for future self.

5. Write test cases.

6. Refactor code, following best practices.

Classic «shutup and calculate».

BTW. Your Shift key is broken.

drran··on How Einstein arrived at his theory of general relativity
Hey, hey, hey, hold the horses.

The very idea of using the 1887 experiment from Stone Age to defend GR seems ridiculous. I understand why you are doing that: there are no modern experiments, which you can use to defend your point, but still. Moreover, interpretation of Michelson-Morley experiment as «it proves that physical vacuum does not exist» is frivolous. Let me quote Wikipedia:

> The Michelson–Morley experiment of 1887 had suggested that the hypothetical luminiferous aether, if it existed, was completely dragged by the Earth. To test this hypothesis, Oliver Lodge in 1897 proposed that a giant ring interferometer be constructed to measure the rotation of the Earth; a similar suggestion was made by Albert Abraham Michelson in 1904.

> the first interferometry experiment aimed at observing the correlation of angular velocity and phase-shift was performed by the French scientist Georges Sagnac in 1913. Its purpose was to detect "the effect of the relative motion of the ether".

> In 1926, an ambitious ring interferometry experiment was set up by Albert Michelson and Henry Gale. The aim was to find out whether the rotation of the Earth has an effect on the propagation of light in the vicinity of the Earth. The Michelson–Gale–Pearson experiment was a very large ring interferometer, (a perimeter of 1.9 kilometer), large enough to detect the angular velocity of the Earth. The outcome of the experiment was that the angular velocity of the Earth as measured by astronomy was confirmed to within measuring accuracy. The ring interferometer of the Michelson–Gale experiment was not calibrated by comparison with an outside reference (which was not possible, because the setup was fixed to the Earth). From its design it could be deduced where the central interference fringe ought to be if there would be zero shift. The measured shift was 230 parts in 1000, with an accuracy of 5 parts in 1000. The predicted shift was 237 parts in 1000.

So, Michelson-Morley experiment confirmed that physical vacuum is dragged with Earth, and then Michelson–Gale–Pearson experiment confirmed that it is not completely dragged by Earth. It far from «physical vacuum doesn't exist» mantra from «shutup and calculate» guys.

In this century,

* the existence of Higgs boson, which gives mass, and Higgs field, which exists at every point of our Universe, was proved in 2012;

* the existence of gravitational waves in physical vacuum is proved by LIGO/Virgo interferometers.

Thus, today we have Higgs field, which is presented at every point, which can be used as 0 point, but we cannot detect it. However, we can use CMB (light from distant galaxies with red shift z=1000) as 0 point.

IMHO, relativity is not necessary at this point.

drran··on Why is the Zoom app listening on my microphone when not in a meeting?
Desktop environments have nothing to do with that: it's the job of distribution. `gksu` is popular to run graphical apps under root or another user, for example, until it was removed from distributions because distributions don't want to allow users to run untrusted apps as root.
drran··on Why is the Zoom app listening on my microphone when not in a meeting?
So, give separate X server (Xephyr, Xnest, Xvnc) per app for increased security. They will be isolated from clipboard, window titles, and broadcasted key events.
drran··on Why is the Zoom app listening on my microphone when not in a meeting?
Separate user for untrusted apps is the proven way to do that in UNIX. :-/
drran··on Why is the Zoom app listening on my microphone when not in a meeting?
All system daemons are running this way. It's the standard way to isolate networking services on UNIX.
drran··on Why is the Zoom app listening on my microphone when not in a meeting?
Security is compromise. You can share your whole home directory, if you trust the software, but it will make any kind of protection useless, or you can write a helper tool, which will grant access to a single selected file using a hard link, to make alias for file content, or synchronize files between directories, or mount a shared directory to both container and your home directory, or use SELinux to grant access to a selected directory only. Chose your own compromise.
drran··on Why is the Zoom app listening on my microphone when not in a meeting?
In Linux, just run an app as separate user. Linux is a multi-tenant OS, so users are well protected from each other. If you need to share files with program, share them via a shared folder, e.g. `/tmp`.
drran··on Why is the Zoom app listening on my microphone when not in a meeting?
You can run each program in full screen on a separate instance of Xephyr or Xnest, so the program will have a whole separate X server to play with in isolation. Good for running Raspberry Pi desktop via `ssh -X` or `ssh -Y`.
drran··on Why is the Zoom app listening on my microphone when not in a meeting?
Linux distributions are FOSS. They provide as much protection as I need. I can run untrusted applications in a container, if I WANT that level of protection. For FOSS software, I don't want it.
drran··on Thank You, Valve
