Ah, no, like most journals (although NAP is not stricly a journal, PNAS is), there isn't a direct PDF link (OP: try to click that on a clean browser and you'll be disappointed).
You cannot make the cost-efficiency argument without acknowledging all the costs which aviation and automotive travel externalize: air and water pollution, damage to wildlife, global warming, lack of walking/cycling infrastructure, rising sea levels... a disproportionate part of which are born by poor or faraway people who have no choice in all this.
Edit: forgot about noise pollution and about flooding risks (due to impervious surfaces like runways and parking lots).
I also doubt airfields and planes require significantly less maintenance than trains and tracks, but I have not researched that.
Bollards are good at preventing the inconsiderate from parking on the sidewalk. For fewer people to be killed by cars, however, you want transportation infrastructure which does not rely on having fast metal boxes in close proximity to pedestrians (or cyclists, wheelchair users, etc).
In some places I’ve been, the sidewalk and road are separated by mature trees, with bushes between the trees. It enforces safety, adds distance between cars and pedestrians, and adds ample shade.
In intersections, pedestrian islands are protected by bollards. In Singapore for example many of the busiest roads even have pedestrian bridges.
It’s a major contrast with my experience of California, where any non-automobile transportation method is an extremely hostile experience. Pedestrians and bicyclists are truly second class citizens on the roads unfortunately.
The investigation partly relies on notes seized from the defendants which mention various privacy tools: GrapheneOS, LineageOS, Signal, Silence, Jitsi, OnionShare, F-Droid, Tor, RiseupVPN, Orbot, uBlock Origin…
According to investigators: "these elements confirm they were willing to live clandestinely".
According to the prosecution: "these notes consituted a real playbook allowing anonymous use of a phone, showing the person was willing to live in secrecy and hide their activities".
absolutely disgusting, you're telling me that you don't want to be stalked 24/7? that you don't want the whole world to know everything you're doing? how dare you imply that you're a human being and that privacy is one of the most important rights you have? now dance monkey, dance /s
to quote professor farnsworth: I don't want to live on this planet anymore
Students in France protested multiple times at least partly against Parcoursup, the government software where high school students enter their choices for higher education and get selected by universities.
As soon as you start having you own server/network rooms, yes.
You will have to monitor your HVAC systems, your fire extinguisher systems, your alarm systems (for smoke and water leak detection), your electrical systems... You will need to make decisions about which type of system to install. You will have to set up maintenance and repair of these systems and interact with the specialized technicians who come to service them.
Not saying you have to become an HVAC expert, but you will definitely learn some stuff outside of computing/networking.
