which was simply asking if there are ways to password-protect files. 

..extremely capacious range of knowledge probed to be reduced to a few sentences that will be a farce of an answer.. some people spend live on it..

7zip is known for using AES-256.

https://en.wikipedia.org/wiki/Advanced_Encryption_Standard

But what really matters is what block mode..

https://en.wikipedia.org/wiki/Block_cipher_mode_of_operation

See the image encoded with ECB block mode:

The lack of an initialization vector can have bad consequences..

Is there any such apps that I can send a file to someone but he can only read the file with the password that I provide to him?

Obviously. But the question is whether you or anyone should trust them.

I know that I can do it by sharing on Google drive but is there more convenient way?

it is the silliest idea to do..
and has nothing to do with "convenience"..
unless "convenient" means "total insecurity"..

Then what for to password protect it in the first place?

I’ve had documents sent to me that were password protected. Microsoft docs and pdf files

Protecting against interception of information is one side of the coin.

The second side is whether the data that was sent came from a legitimate source..

And AFAIK most hermaphroditic animals are invertebrates so there might be some limits on that mode of reproduction.

Current animals and organisms are simply the lucky survivors of mass extinctions in the past.

You might as well ask why a man has five fingers, or why he doesn't have six legs.

An interesting case is sequential hermaphroditism in fish that change gender:

https://en.wikipedia.org/wiki/Sequential_hermaphroditism

https://en.wikipedia.org/wiki/Moon_wrasse

If you look at the biomass of organisms on Earth, you will see that most living organisms do not have sex at all or are hermaphrodites.

Is having male and female in separate bodies a practical reproductive plan for humans, mammals, birds and etc? 

Mammals evolved from reptiles, and these evolved from amphibians, and these evolved from fish. Something that works will not suddenly change into something else because it would disrupt the whole process of fetal development. Changes happen very slowly over millions of years.

You would think this would be blindingly obvious.  iNow might be right - possibly a way to set a cookie.  Embedding videos on a forum can result in cookies being set by the video hosting website, potentially collecting information about the user's browsing habits.  I would advise everyone do a cache/cookie clean after watching.

A regular user does not have access to YouTube cookies..

There are three types of cookies. HTTP cookies, JavaScript local supercookies and JavaScript session supercookies. JS cookies are set and retrieved from JavaScript. HTTP cookies are sent from your browser when you visit the site. They are all stored on the user's computer. Optionally, they may also be stored on the server. It depends on the webmaster/administrators of the visited site. Clearing the cache and cookies does not guarantee no recognition if you visit the same site again. People use Google accounts, Apple IDs, etc. Without a Google account on your smartphone, you can't use the Google Play Store, for example. And every time you visit YouTube, you are asked to sign in, etc. Google stores the IMEI of your smartphones when you create an account, or sign in to the existing account from the next model, i.e. they know that someone sold you a smartphone, gave it to you, that you stole it from someone, that you found someone else's smartphone, etc. etc.

You would have to click on his personal website to use any of these cookies. Or he would have to use web beacon on his website.

The amount of knowledge is quite large. He would have to have his own server, know HTML, CSS, JS, PHP, etc. etc. to be able to create such ID theft functionality. And it would work regardless of whether he wrote a YouTube video post or anything else. You wouldn't know that his post was using this technology..

Why is the sun moving so fast in this solar eclipse video?

Clouds are moving in the foreground, which gives the impression that the sun is moving..

Scientists have spent decades on this, a lifetime, and you want us to explain everything to you from scratch.

Start from learning how to measure distance to distant stars..

https://en.wikipedia.org/wiki/Stellar_parallax

Once you know how to measure distances to near stars, move on to farther stars, then to galaxies, and then to distant galaxies..

If a galaxy is farther away tomorrow than it is today, the obvious conclusion will be that we are receding away..

All this is based on the finite and constant speed of light.

Not really ... almost all people don't know they observe a mix of past times and they think they observe the present ; also almost all people don't identify the lies from omission or well hidden in beautiful words or lies of ' great manipulators'...human brain is guilty by their because we are programmed to survive use sometime lies and we are not programmed and ready to know the absolute true ...the true nature of reality 

I stick to original definition of a lie as something false. The delay in delivering the message is irrelevant here.

Otherwise, you can call the Sun a lie, because it is 8 minutes late on the Earth. Which will be ridiculous.

Calling it a "lie" to receive correct information with some delay is a serious misuse. The same is true of e-mails, text messages or social networks, where time is counted in milliseconds or even seconds.

Lying, as far as I remember, is receiving incorrect information.

delay in receiving a message does not make the message false.

Which there's a shortage of, so it's getting expensive.  I've seen estimates that we will run out in 100-200 years unless some other sources are found or ways to reduce loss.  

There are smarter ways to use this precious helium than balloons and airships.

The problem is that words don't mean the same thing if you say them in different parts of the world.

Thanks mate, that lil ol neg is acknowledgment that you've run out of steam on this thread (which kinda makes me right, go me...).

Is this a big surprise? Why does anyone waste their time on you when you reject common knowledge.. ? I have provided the data of Cambridge University.. If you disagree with them, write to them to update their data according to your pet theories..

The point is in the flawed thinking, 

Your personal interpretation of words is irrelevant, since we use a common language, you have to use the same interpretation of a word or sentence as everyone else on the world, otherwise you won't be understood if you write a public post e.g. just like every day you do so..

@swansont @Phi for All

Instead of you, we have the Cambridge University dictionary:

https://dictionary.cambridge.org/dictionary/english/self-made

"rich and successful as a result of your own work and not because of family money"

I used the well-known Cambridge's dictionary definition of the word, and instead of approval ("acceptance of the statement") I got 4 negative points in this thread, for no reason..

ps. This is semantics. Your family bought you food, gave you other goods and so on when you were young. The point is in the details.

The issue is what someone understands by "self-made billionaire." I have expressed what most people in the world mean by it.

Self-made means you did it yourself, with minimal outside help. Not just help from parents. It suggests that anyone can do it if they just work hard enough.

People buy stuff somebody produce..

Without buyers, fortunes cannot grow..

IOW, how can you literally do it yourself if you rely on customers?

If I bought/mined 1000/10000/100000/1000000 BTC 15 years ago, am I a sell-made millionaire/billionaire?

There’s a baseline of support that anyone can get, but most uber-wealthy get far more than that, such as subsidies or tax breaks for individuals or companies not available to the average person.

If someone hands you a million dollars and you can parlay that into a bigger fortune, good for you. But since most people don’t have access to a million dollars, it’s a tad insulting to imply that it’s a path to wealth accessible to all.

...if someone has earned several hundred million dollars from PayPal alone and has gained a globally recognized position, such a person is in a slightly different position than an ordinary John Doe, if we are talking about receiving government investments after completing a several dozen-page contract with the government..

I haven't seen any good arguments about billionaires pulling themselves up solely by their own bootstraps. It's well known that billionaires can only exist if they steal the money legally from everybody else. Does anyone have an example of a billionaire whose employees love them as much as the stockholders do? All I ever hear about is how the people who do the most work get the least pay, and the person who gets paid most does nothing but figure out how to get paid more.

"Self-made millionaire" means that someone did not get millions from his parents. Heritage them.
"Self-made billionaire" means that someone doesn't get billionaires from his parents.
And that's it.
The real way to get millions or billions is under the rug, which you don't have access to.

Now you (plural) came up with a new definition that self-made billionaire cannot get money from anybody else or government.. They how can they get it otherwise? Or how can you get any money? You (scientists) depend on government subsidies the most...

5 minutes ago, Phi for All said:

Or you were simply wrong to conflate a private salary from the government with subsidies, tax breaks, and other economic incentives Elon Musk got from the government. I'm going to go with that rather than chase this red herring.

I bet Elon would survive collapse of government subsidies.. unlike a regular scientist who rely on it on a daily basis..

The whole thread is bizarre for me.. as it is about semantics.. A long before Elon even imagined anything he had milllions from selling PayPal..

On 4/4/2024 at 3:51 PM, Phi for All said:

I am surprised, and actually shocked, to see you trying to claim that a government salary is the same as government subsidies. Subsidies for Musk, for example, include favorable loans, incentives, tax breaks, and environmental tax credits. They even built him factories. 

So your post is actually an accusation of many crimes on both sides, if the government builds someone else's factories with government money, so it's fraud.... Did you come to the FBI with your claim of a crime being committed by the government and a private company?
If they build a factory for $1B and sell it for, say, $2B to a private company, they will make $1B. So the whole construction of the factory was an investment.
