"tonality characteristics" and "soundstage" are subjective words that have no concrete definition. Other similar words are "grain", "speed", "separation", "resolution". They can't be objectively measured, and are most likely just another function of frequency response.

The differences between headphones are most likely your ear having a different shape from the reference ear used to make the eq targets, leading to a different final perceived frequency response. (or limitations in the accuracy of the measurements, most targets I believe are "smoothed")

I'm going to trust the (claimed, who knows, maybe oratory1990 is a liar) consensus of audio engineers over your anecdotes. As I said there are plenty of audiophiles whose "lived experience" is that $2000 golden cables are necessary and that they can tell the difference between any $200 and $1000 DAC (even though a decent DAC in that price range already has a dynamic range and signal-to-noise ratio of 100-120dB which should be totally indistinguishable from perfectly clear audio for all humans

personally the only decent-ish headphones I have are DT 880 600 ohm and a JBL 760NC. The latter kind of fills all the boxes of being a wireless headphone and has poor reviews and a poor default sound profile. But after EQing both, I can't really notice any difference except when very carefully doing side-to-side comparisons (besides the much better comfort of around-ears vs over-ear).

In contrast I believe I can tell, with some songs, the difference between 320kbps mp3 and flac (just 44.1khz), but even there I'm not sure it's not just placebo

Usability is kind of secondary, android should have jamesDSP and the venn diagram of people that know the best headphones to buy (instead of beats by dre) and who can setup an EQ (install an app and follow written instructions) should have a lot of overlap

I will say though that more expensive headphones are probably going to last longer and are probably much more comfortable

more accurately, average person has a higher tolerance for bullshit than for spending many hours learning something new or spending potentially years applying for citizenship in another country

The thing is, distortion (maybe more accurately called nonlinearity) is the only known objective way to measure the difference in sound quality between two headphones EQ'd to the same target. (there are some other measures like signal-to-noise ratio but they are even more useless) And the difference in the value becomes very small for a technically good $50 headphone and the best headphone ever made. (technically good eg. the natural frequency response isn't crazy far from your target and the nonlinearities are competitively low)

Now, two headphones EQ'd to the same target, even if both are measured to result in the exact same sound, won't actually sound the same to your ears because the "head dummy" used for the test doesn't have the same ear shape and characteristics as you do. But unless there is some strong evidence that the headphone manufacturer has a better methodology than what is publicly available, then there's no reason to think they are somehow able to account for your specific ear's needs without custom designing the product just for you. - You're left with having to either EQ yourself, or using dozens of headphones and testing which you like the most. And the EQ route is going to be much faster and cheaper

for sources, these discussion seem the most useful

you can say that most people who spend a lot of time and money trying to achieve "perfect audio" seem to think that EQ is only a supplement to already good headphones, but given that there has been no success at objective measurements of quality and that many people swear the thousands they spent on insulated golden cables improve their audio quality, I err on the side of saving my money.

if you use a good equalizer, you can equalize pretty much any headphone to your ideal frequency response, as long as it has a loud enough maximum volume and doesn't have distortion (so any half-decent headphone over $50 should do fine. Some would say you can go even lower)

I wonder if it's common for those steganography techniques to have some mechanism for defeating the fairly simple strategy of getting 2 copies of the file from different sources, and looking at the differences between them to expose all the watermarks.

(I'd think you would need sections of watermark that are the same for any 2 or n combinations of copies of the data, which may be pretty easy to do in many cases, though the difference makes detecting the general watermarking strategy massively easier for the un-watermarkers)

that works for 2 word names eg is_open or is_file, but in this case is_dialog_file_open is structured like a question, while dialog_file_is_open is structured like a statement

We set sail on this new sea because there is new knowledge to be gained, and new bragging rights to be won, and they must be won and used for the progress of all speedrunners. But why, some say, zero A presses? Why choose this as our goal? And they may well ask, why climb the highest mountain? Why, 55 years ago, fly to the Moon? Why does Mohun Bagal play the Delhi Capitals? We choose to do zero A presses. We choose to do zero A presses... We choose to do zero A presses in this decade and do the other things, not because they are easy, but because they are hard; because that goal will serve to organize and measure the best of our energies and skills, because that challenge is one that we are willing to accept, one we are unwilling to postpone, and one we intend to win, and the others, too.

for a large project, you can probably look at the history of issues, if there are lots of issues that are 5 years old, it's almost certainly legit

All 9k stars, 10k PRs, 400 forks & professional web site are fake?

Technically, it is entirely possible to find a real existing project, make a carbon copy of the website (there are automated tools to accomplish this), then have a massive amount of bots give 9K stars and make a lot of PRs, issues and forks (bonus points if these are also copies of actual existing issues/PRs) and generate a fake commit history (this should be entirely possible with git), a bunch of releases could be quickly generated too. Though you would probably be able to notice pretty quickly that timestamps don't match since I don't think github features like issues can have fake timestamps (unlike git)

though I don't think this has ever actually been done, there are services that claim to sell not only stars but issues, pull requests and forks too. Though assuming the service is not just a scam in itself, any cursory look at the contents of the issues etc would probably give away that they are AI generated

as many iterations as it takes

    
void* x = &x;
char* ptr = (char*)&x;

while (1) {
    printf("%d\n", (unsigned int)*ptr);
    ptr--;
}

  

looks like work on the android client started in 2011 (or at least, that's when it seemingly started using version control)

the app was released in 2014

so it has likely inherited decisions from ~14 years ago, I'd guess there is a several year gap where having a native desktop app was not even a concern

Also the smartphone landscape was totally different back then, QT's android support back then was in alpha (or totally nonexistent if the signal project is a bit older than the github repository makes it seem), and the average smartphone had extremely weak processing power and a tiny screen resolution by today's standards. Making the same gui function on both desktop and mobile was probably a pretty ridiculous proposition.

monospace means the width of the "whole" character is always the same, but the width of the visible part of the character is not (imagine how large the dot would have to be for that to work)

are you a goldfish.

When you meet a bear in the woods, there is a 0% chance they will notice how the situation bears a resemblance to the popular meme and proceed to mansplain about how bears are more dangerous.

This is and has always been the one and only reason women choose the bear. But one question yet eludes us: how did the cycle start?

or that I don't want to (google what it is and then) press some weird keybind and spend minutes scrolling through the list of emojis when good ol' emoticons do the trick
