Reply to ELI5: When we call any customer support, an automated voice asks us to press specific keys for different options. How does it know which key I am pressing? by [deleted]
The buttons work by sending out two tones, the combination is unique for each key. The equipment on the other end interprets the tone.
You can see the tone and how they are used at https://en.wikipedia.org/wiki/Dual-tone_multi-frequency_signaling#Keypad

Reply to comment by ExternalUserError in ELI5: How is that Pantone colors don't have direct RGB counterparts? by ExternalUserError
"So was the CMYK conversion impossible or just rushed? Like if you took the Pantone color you wanted to a color matching computer or something, and printed out a CMYK, they’d still be different?"
Converting to CMYK causes a color shift because Pantone's spot ink formula has at times no 100% direct translation to CMYK. Spot inks are more like paint at the hardware store where RGB/CMYK is like scanning a paint chip from one store and having another store mix it. Sometimes the results are a bit off.
"And how does this work for a computer file?"
It's all coordinated magic between the graphics software, your operating system, and the output device. Your graphics app embeds a color correction profile which the OS uses to instruct the printer how to match the colors. But this tech is not a 100% rock solid science. Sometimes math doesn't convert colors correctly. That's why us old-timers will get a test print from the print shop before making an expensive mistake. Technology can fail.

Reply to ELI5, Why can't STDs be cured/irradicated by isolating the disease through infected people? by AnanomusMan
Because people don’t get tested and because theirs little to no consequences for knowingly spreading STD’s.

Because at any given time millions of people have stds. How do you isolate them?

Reply to ELI5: Why is burning wood (local, natural) considered bad for the environment, yet naturally occurring forest fires considered good for climate stabilization? by prendrefeu
There are a couple of reasons why wood burning might be banned.
Some towns are located in valleys that retain smoke, so if a lot of the residents burn firewood as fuel all the time, the whole town is continuously cloaked in smoke. That's bad for everyone's health. Forest fires are short term events that last a few days and then end.
Forest fires may have some benefits but they also destroy homes and kill people, and firepits might be banned where you live in case you accidentally start a larger wild fire, if you are in a high risk area. Controlled fires are only set in areas and at times of the season where they can be closely monitored and controlled and hopefully not end up creating a disaster.

In addition to what everyone else has said,
>Or do you print . . . in order to see what it will look like and adjust?
Many printing/publishing companies have special laser or inkjet printers that have been specially calibrated using a standard called SWOP (Specification for Web Offset Publications; not "Web" here refers to web press printing not the world wide web) to closely mimick what something will look like on the industrial scale printing presses. In the early days of my publishing career, I worked on paper page proofs made by a normal mediocre quality office printer and also got a stack of high quality SWOP proofs just of the art.

How does this behave with different kinds of light sources? Some materials are more reflective in some frequencies than others, so a print in one material may look quite different from another when you bring them both under cheap fluorescent lights or something.
Or does Pantone specify a particular kind of light source too?

It really is, which is why I gave up on it. And with so many new types of screen technologies, it’s only gotten worse. Oh well

> That's why you're not supposed to burn wood, it releases more CO2 into the atmosphere and makes it worse.
It only releases the carbon dioxide that the tree itself took out of the atmosphere while growing. That carbon is part of the current carbon cycle.
Coal and other fossil fuels are the problem. The carbon there has been out of the loop for so long that life's carbon cycle has adjusted for its absence.

Thank you. I mostly drink water, work out and eat healthy so I was confused a bit. It really does go away after a fresh breath of air.

So are these images with Pantone colors including extra metadata that’s useful for print but less useful for on-screen?

Reply to eli5 why workers who make tips, have to pay back some of their tips a the end of the night? by 420goattaog
It's called tip share; there's some inequities between the "back of the house" and "front of the house" when it comes to every restaurant. No matter how busy you are, the back of the house (along with some front of the house like bus boys and hosts) gets paid the same amount of money regardless of how hard they work. The wait staff gets paid more the busier they are since they are tipped employees, and more customers means more tips. To incentivize all employees to be more efficient, the restaurant takes some of the tips and redistributes it to all employees. Often they just take a percentage of credit card tips.

The reason firewood is banned indoors is not because of its carbon. (All firewood is carbon low, because the tree got it out of the air, but getting it to you probably used gas) Firewood is bad because it both causes chimney fires, and contains large particulates that lower air quality. Think cancer causing smoke.

Thanks for the explanation.
So was the CMYK conversion impossible or just rushed? Like if you took the Pantone color you wanted to a color matching computer or something, and printed out a CMYK, they’d still be different?
And how does this work for a computer file? The computer monitor, even if a very high end one, still just has glowing primary color pixels. If I screenshot an old Photoshop open with Pantone colors, the screenshot should look identical on screen, but it would be different printed out?

Because it’s impossible to make a true blue or a true red something about not being able to find the correct pigments (it’s been along time since trade school. I’m an offset printer by trade)

There's an apartment building in the city I live thats from 1308. - Europe (city withheld for anonymity) and it withstood two world wars. So brick and stone is pretty long lasting. 100 years is not long.

I'm living in a stone building in Europe that is 300years old friend. If you build a wood house today with the aim of handing down to your children, you're grandchildren are inheriting the problem.

The thing is that while you can get the monitor to display the same color you see on your Pantone guide someone with a different monitor may see something completely different, Pantone is used so you can tell someone across the world “I need this plastic to be this kind of red” and they use the exact same color, pretty useful in manufacturing or advertising for example, Pantone has guides for a lot of materials so it’s not only what you see on screen

Fuck everyone that hates on you because smoking is bad... 99% of smokers know it's bad, stfu already people...
The honest answer is that it's one of the earliest signs of CO Poisoning - And given you draw in a lot of CO when you smoke... you have a large scale intake of CO. It passes within minutes of "Fresh air" - It's also why smoke indoors long term with no ventilation will cause the same results for everyone around you.
