Logins are session-based. You could tie publishing of a package to a signature from the key, then 1 tap = 1 package hash.
But yeah, if the system is compromised and the attacker is doing interactive attacks they can wait for something that requires using the key and then trigger the publishing and win a race against the real prompt. To the user it might just appear like having to tap twice.
Distros have mirrors and they don't know which one you use. The updaters don't send user IDs and downloading the package lists is separate from downloading the packages. So targeted backdoor distrubution is much harder than a company's web UI with user logins targeting a specific user.
I suspect github might be preventing some price discrimination. If you got feature request from @amazon.com you could point them to your commercial support offering or something. Some namehandle filing an issue on github makes it less obvious who's asking for it.
Shallow color gradients (e.g. blue sky or anime) result in visible banding on 8bpc displays, which is a large fraction of displays.
Ordered dithering is GPU-friendly, so it's useful to reduce higher-bpc content to those display formats without introducing banding.
Ships are giant hunks of metal and radio emitters. They light up on SAR satellites[0]. Sentinel-1 gets whole earth coverage and a revisit time of 1-3 days[1] with two active satellites. And that's the public stuff, if you can afford a fleet or even some extra fuel to steer them into interesting orbits you can get faster revisits.
There is a french company (https://unseenlabs.com/fr/) that specializes in tracking ship at sea through observing their RF emission from space. Cool tech. I'm pretty sure their main clients are not all civil...
5-10 ships moving at speed across the ocean. Blasting the skies with radar.
Its as easy as anything is to find it in the ocean. And were pretty damn good at tracking ships at sea even small fishing vessels let alone a floating city.
The threat model to CSGs are basically nuclear submarines from nations that would simply tail the group if needed.
U.S. anti-submarine doctrine for surface vessels is pretty much just “run away”, that’s how dangerous subs are, so that’s why U.S. CSGs often include an attack submarine escort.
The sidebar mentions heavier particles having a pronounced Bragg Peak[0] and also existing approaches like multi-beam targeting. The FLASH effect in the article is yet another tool to limit the surrounding damage.
