Or why not just use (big) mirrors?
I mean, this is a thing with solar concentrators already, haha
and for those the heat is a feature :p

You can shape them that no matter how the light falls on it, it will align to the center. Kind of like how satellite dishes work but in reverse.
how do you do this, actually? I’m curious about the details because I just watched a video on compound parabolic reflectors, haha
a regular (ideal) convex lens with a single focal point will have the image move around as the light source moves across the sky. AFAIK satellite dishes tend to be paraboloids, which focus parallel rays onto the focal point, and if you change the angle of the light source, you’ll start losing focus. Stuff like the DSN and radio telescopes absolutely do have to aim and track their targets (or are forced to follow the rotation of the earth).
satellite dishes that are aimed towards geostationary satellites don’t have to move (because their targets are stationary in the sky), while stuff like starlink tracks targets with a phased array.

well, adding lenses kinda requires motorizing the panels to track the sun, right? otherwise the “hot spot” is going to move around across the day/year
is there a way to shape the lens to mitigate this?

- Comment on StopKillingGames - Yet another reminder for European citizens to fight for software ownership before the timer runs out. A signature takes mere minutes and preserves many games and lots of fun. 3 weeks ago:
and like, one of the options would be for live service games to say “we are planning to operate for {number} of years” and people would know to spend their money accordingly
it would be transparent and informative and people would be empowered to make their own decisions
- Comment on Proton joins suit against Apple for predatory practices that harm developers and consumers 4 weeks ago:
My read on this is that he’s an idiot who wanted to air a contrarian opinion ('cause that’s how tech CEOs be), and focused in on a very literal/pedantic view of the issue without taking into account the context (which is that the Trump regime is facist and also just… lies, like, all the time).
Whether or not being a pedantic idiot is better or worse than being a Trumpist (or if it’s even a meaningful difference) is up to you, of course.

it’s a shame commonmark stalled and then markdown variants proliferated again because of that :/

great article, and I had no idea that happened to Brian Krebs, of all people! o.O
I do think the EFF makes a good point though, and I think personally I tend to be biased towards content neutrality over moderation (at least, more strongly the larger the platform is, and Cloudflare is very large). Not to the point of Xitter, obviously, but I think there’s at least a reasonable argument for Cloudflare in this case.
that said, after some searching, I did find the following two articles, and I find their arguments against Cloudflare very compelling:
Fortunately I’m already using end-to-end SSL certs via Caddy, but now I’m considering just moving off Cloudflare entirely and instead providing regular backups to Internet Archive–most of the stuff I host is entirely static and very lightweight.
