Either start with Mistborn #1: The Final Empire or The Stormlight Archive #1: The Way of Kings. They are his main series, and generally regarded as his best stuff. Would probably recommend Mistborn as it's been finished, and the mainline story is only 3 books.
I struggled with this too, and the conclusion I've more or less come to is that you can't. In the end, you have to figure out what is worth prioritizing and what you are okay with letting fall to wayside. The one practical thing that I've found to be useful is to try to think in terms of what I don't want to spend my time doing - and then actively trying to avoid doing those things - rather than trying to think of all the things that I want to do.
Another thing to keep in mind is that every couple of years, an internal or external shift is going to change what you think is important and what's not worth the effort.
Maybe today you want to focus your time on learning different things and don't want to focus on your job. But then you turn 30 and you realize you want to focus on your career and spend less time learning random stuff. Just make the best decision you can at that moment with the feelings and data you have.
IIRC its Night Vision Device. Essentially night vision cameras have triangle shaped iris which causes triangle shaped lens flare - hence the triangles in the footage.
The Wikipedia article[0], has some interesting speculation about this. Main ideas behind the cause seems to be either some directed energy pulse or potentially a ultrasound weapon. These kind of invisible weapons are utterly terrifying to me and I feel that they'll just become more prevalent in the coming decades.
So this a super hot take, but someone is asking for an ass whooping. This is basically an act of war. I'm going to just leave it at that. This isn't some random hack, kinetic attack demands kinetic response.
This is a sophomoric understanding of our complex nation and its many power centers. Cynicism is an easy masquerade for wisdom, but don’t fool yourself too.
It seems like some wideband audio and RF sensors would be able to easily detect this. If it's skull penetrating, I doubt you would even have to place them that densely to detect something out of the ordinary, regardless of the directionality of the source.
There's probably a government contract opportunity for a wearable detector here.
I wonder if you'll see more domain specific content aggregators/search engines pop up as people (like myself) because increasingly dissatisfied with the almost populist nature of a lot of Google's search results.
