I don't understand it but clearly there is a market for wasting time and money to print at home.
Lets talk about it then. The resources you want to minize use of are "cost" and "time". It is faster to print a photo on my home printer than drive to a store, and pay them to do it unless I'm printing a lot. If I'm printing more than say 20 pictures, or picures of all different sizes, then it takes longer because of my paper feeder. Typically though I only want to print one or two of a picture to put in a picture frame or give to friends and family
But lets also talk cost. It's about 10c per picture in paper and another bit for the ink. That is about the same as my local shop depening on deals because their prices fluxuate and by bulk. I pretty much call it a draw there unless you catch them on a deal and buy in bulk.
That makes it about the time.
The bicycle stand at the Amsterdam train station is also impressive in its scale.
Haha this, and in my limited experiance, copenhagen.
I do not believe cell phone would work at all at that height and speed typically.
Cellphone towers are designed to emit a beam pattern that looks roughly like a system of slivers forming a donut [in the horizontal plane]. If you aren't directly in that beam for a long enough period of time to negotiate a connection, then it won't work. In cities, cell towers would be denser and each tower would have less power to increate the amount of users possible on the system. While in the countryside, there would be fewer towers at higher power, but less places for the signal to bounce up and intersect a speeding plane.
But, maybe they get luckey
A lot of posts here are complaining/discussing the downfalls of private funding. I don't care- As long as (1) We don't stop _also_ publicly funding pie-in-the-sky scientific research and (2) it is still science. Verifiable and reproducible science.
That is, why can't we just have both? I'm happy that Bill Gates, in his old age, is throwing shit-fuck-tons of money at things he believes to be a problem. Fantastic!
Linux distros have this for sudo actions. They also have a button that terminates the privileged timing window early in the gui, and for cli it is something like:
sudo -k
or
sudo -K
+1 for peaking my curiosity.
