I love reddit so much because you have people casually saying shit like "yeah, i used to build Airports" like that isn't one of the coolest things you can do like ???

Reply to comment by WilliamMinorsWords in ELI5: what are Pantone colours and how can they charge you for them? by jambo5600
Oh wow, I somehow missed that. Thanks.
That's bad. Adobe has been unchallenged for too long. A lot of stuff they've pulled off since CC would have had big parts of their userbase running off if there was a considerable alternative.

Reply to ELI5 how can a hacker crack a password but avoid the "login attempt lockout" timers? by otherother_Barry
That’s called a brute force method of hacking and it is rarely used. If you do want to use that method switch your logic. Same password, but try a different account name. Eventually you find an account using that password

Everyone has brought up some great points, but I will also add in one other aspect that makes it harder to move industries and that is all the supporting business. There have been many cases where businesses try to move their production to new locations to only discover dependencies that make it nearly impossible. For example, when apple tried to move one of their production lines to the US they discovered that no one locally could manufacture some screws for them in their specific size. Companies were willing to start creating the screws, but it would take a few years to reconfigure their production lines.

Reply to comment by jensjoy in ELI5: what are Pantone colours and how can they charge you for them? by jambo5600
This just happened recently. Adobe and Pantone decided that if you open a file, no matter how old, that contains a PMS color, it will show as black unless you pay a monthly subscription for it to show. Last I heard, it's like $21/month per color.
It doesn't matter if you're just an individual designer or even a school. This is obviously aimed at major corporations with major brands who will just pay it. But for everyone else, you will just see a black blob.

Reply to comment by ohromantics in ELI5: Morse code is made up of dots and dashes. How did telegraph operators keep from losing track of where one letter ended and another began? by copperdomebodhi
Enjoy! It can be a dense read but it's worth effort.

Sry that's not an explanation but what paywall did they put up?
Pantone only makes sense in print, on screen you can only get a close estimate of what the color will look like and rgb to pantone converters are all around.

Then congrats you are the first of your kind biological anomaly and researchers would love to dissect your eye...or you did it wrong.

Reply to comment by Relevant_Sail_7336 in Eli5: What is the bodies process of breaking out in hives? by Relevant_Sail_7336
Just to be truthful up front I ain't a doctor. Been an Army Medic for some years and an AEMT so take what ever I say with a grain of salt lol. But a lot of autoimmune disorders have hives as a potential symptom, such as thyroid diseases, arthritis and even diabetes. Anytime those small vessels dilate they can potentially burst. But both hives and burst capillary's, which is called Petechiae, are pretty common in a lot of different diseases. You can get those with out having a true autoimmune disorder as far as I know.

This is just another language that you learn. The dots and dashes are part of it. They are the voices that you hear. Do you text? You don't hear a voice then Just the one in you head as you read it.

Reply to ELI5: Why can we see differences between 60, 144, 165 and 240hz if the eye only can process 60fps? by Xyraph
You may see the difference in quantity if you will follow a moving object with your eyes
In real world if you follow an object it's obviously not blurry at all
Let's say we are looking at a moving 40px circle
In 60FPS an object moving on 480px/second will jump by 8px every frame. The circle remains perfectly same, but as your eyes are following its position continuously, for your eyes it will be blurred between those 8 pixels, a whole 1/5 of the circle.
In 240fps the circle will be blurred by 2px, much less.
The same way you can differ a clean image on a screen from the same blurred image, you can differ the higher-frequirency moving image from a lower-frequirency one.
This also breaks eye's ability to properly follow the object, which breaks the immersion and may be felt by an average human without any extra tools

It really is an incredible transformation. Did see a homeless person asleep in one of the long hallways (don't blame them really) and some dog poop, but those could also be props to get people acclimated to the NYC experience.

There's a lot of psychology that goes into architecture. A lot of things are the way they are because they make people comfortable.
Airports have to have large spaces — at least in two dimensions. The third dimension could be short without sacrificing function (other than perhaps ventilation), but it would feel cramped and oppressive. It's no different from a big-box store — a lot of them have higher ceilings than they'd otherwise need, simply to make it feel comfortably spacious.

Reply to comment by sahnti in ELI5: Why are the colours in rainbows in separate lines? by Oheligud
Well a rainbow isn’t 6 or 7 colors inherently, but I perceive it as 6 distinct colors- others who use only 4 words for colors would be able to distinctly separate where their 4 perceived colors begin and end. There are fascinating studies about different cultures and their ability to actually tell the difference between colors.

Reply to comment by WW-Sckitzo in ELI5: Morse code is made up of dots and dashes. How did telegraph operators keep from losing track of where one letter ended and another began? by copperdomebodhi
It's still pretty pervasive in the marine industry, however most of the time the letters don't matter so much as what they mean. I've forgotten half of the alphabet, and definitely couldn't translate a sentence from the flashing light the way I was trained to, but I encounter at least one of the various single letter codes just about every day on the water.
Racons (radar beacons) transmit an identifying letter that appears on our radar, letting us visually identify important points of land. For example I can easily distinguish the entrance to the Fraser River from the sandflats at Robert's Bank because they have different letters.
Flashing morse A lights are used on fairway buoys to mark safe water.
Flashing morse U lights are used on oil rigs to signal a danger.
Morse O is the emergency signal for a man overboard. Every crew member knows where to go and what to do immediately upon hearing that signal.
Different morse sound signals can be used to indicate you're turning to port, starboard, overtaking a vessel, moving astern, or concerned about what the other vessel is doing - given the prevalence of radios only the last two seem to be used regularly, but if someone wasn't responding on radio it gives me a way of letting the other ship know what I'm about to do.
Similarly, others are used as fog signals to indicate what type of vessel you are and what your status is (for example I can tell a normal power driven vessel from a tugboat or vessel restricted in its ability to manoeuver).
And as the aviation guy mentioned, we've got some aviation electronics on board transmits our identification code when we're doing helicopter operations as a backup to help them find us.

I've only ever seen separate lines in artwork/recreations of rainbows. Rainbows in real life, or photos of them, look like the color gradients you see in color pickers (like in Photoshop).

Suppose it's for the back-end, non passenger section of the airport.

Reply to ELI5: Why does it seem so that the value of violins grows more/higher than it does for other instruments? by Holiday-Snow4803
it's because the violin in question is an antique made by a man who made exceptional instruments that are still functional today. and because there is a limited supply, the price goes up accordingly.
it's like asking about the price of a painting that was made hundreds of years ago...
antiques and artwork are essentially priceless.

How interesting that today is the day I finally revisit my FCU map update project at work and shit all the info into one document. We have like 20 of these goddamn things all scattered around the building in storage rooms, and areas that are surrounded by stairwells that seem to tie themselves into knots. The current maps being used are photocopied blueprints from the 1980s marked up with a highlighter.

Reply to Eli5: Why does ceramic break tempered glass so easily. by jannesb
Tempered glass is under very high internal stress from the process of cooling it rapidly.
Ceramics are harder than glass so the impact of the two mostly transfers the force to the glass which causes the stress of the internal glass to exceed its ability to hold its structure. AFAIK.
