For the most part they are. You can find enormous troves of classified documents that have been made public, and a huge amount of once top secret technology and engineering eventually makes its way into the public space.
sure but the HUD from the F-35 is very specifically designed to work in an F-35. It's very similar, and comes from the same family, as the software running on other planes. But it's not identical.
And yes, performance limits would be hard coded into the software because the HUD needs to alert the pilot when they are getting close.
Edit: and that's ignoring the fact that a lot of this stuff comes from private companies so you'll run into things like IP/patent laws
"the guy" who invented the space pens is a whole entire company that makes many things and is staffed by many people.
The "space pens" are just their normal pens but with pressurized ink cartridges and special ink (and the development was paid in full by Fisher) but they were bought at MSRP by NASA. And because everything NASA does is public domain, you can actually see the original PO for the pens! They spent $2.25/pen in November 1967 which would be worth about $28 today.
I used to think that if you wanted anything harder than alcohol you were gonna have to go to the sketchy part of town and meet with some shady guy in an alley and hope you don't die.
Now that I'm an adult it's bewildering to me how many people rely on weed/coke/Adderall/alcohol/etc just to get through the day. And it's every career and job I've been in! Everything from a shitty kitchen job to now I'm 1 level below the C-Suite.
I'm 28 so not old by any means, but at this point I have an established career with a lot of responsibility and a number of people working under me.
Very regularly I sit in my office and wonder who the hell decided to hire me for this job. Like I'm just some dumb kid! Obviously it's not true, and imposter syndrome is a hell of a drug.
This isn't just good advice for driving, but good advice for life. None of us really know what's going on in each other's lives, all you know is a vanishingly small sliver.
We all need to be nicer to each other. It's a cold world out there, no reason to keep shoveling shit on top of someone.
I've said "nobody wants to hear your bullshit" which also tends to have a very large effect. Which way the effect swings is completely unknowable but the dynamic will be very different after haha
You can literally just download all of Wikipedia in one go from one URL. They would rather people just do that instead of crawling their entire website because that puts a huge load on their servers.
That's only 800x480 though. The BOOX ultra has a screen resolution of like 1900x2400 IIRC.
plus it has other nice features like it's already made and it's much thinner than your rpi version, and runs a custom android ROM so you can just install android apps.
That's the thing though, websites have gone away from "fingerprinting scripts" and have started finger printing you by what you serve, how and when you access it, and other things that they can all collect purely on the server side. The rest is just for advertising and data collection for improvements.
That's the whole show haha. The gang is just continuously the worst possible people
