*Technically*, this is very cool, impressive, and generally an elegant work of art. *Pragmatically*, I see 2 flaws in their thesis (as explained on the about page): >> "The entire network already consumes 10% of global electricity production with traffic doubling roughly every 2 years" I think the implication is electricity consumption will also double roughly every 2 years, but Moore's law actually operates on appro…

The state of Missouri pushes SSN sorting to the browser. I’ll allow it.

While I agree with most of your points, I think that these dithering images use less client-side power than a regular image compression (e.g. JPEG or PNG). The dithered images are smaller (according to them), and I don't see why they would use more CPU per byte to decode than JPEG.

A lead-acid battery doesn't seem like a good choice for this application. Prolonged discharge states cause the lead sulfate to crystallize which is irreversible, making it impossible to recharge the battery.

A lithium chemistry might be better, since that prefers partially discharged states to being fully charged.

A suggestion: in bad weathers, the server should turn off during the time when there is less visitors and less sunshine. That probably could help it to serve a few more days (Of course the visitors must know when is the best time to visit)

Hey @dang, you wouldn't happen to know anything about how Hacker News is hosted, would you? Reading this has piqued my curiosity. If time / your position permits, of course.

From what I remember from previous posts by dang: It's living on a single dedicated server with some hosting company (I think you can look up the IP to figure out which) - at least a while ago the code also was single-core, not sure if that is still the case. (in the past it used cloudflare for caching, but hasn't in a few years)

It's M5 Hosting

If it's a deep discharge lead acid and it is maintained it can last 5-6 years.

I thought Moore’s Law is about the density of components on an IC—what about it suggests a constant energy usage of IC as it gets denser?

This property is called Dennard scaling. It mostly does not apply to the latest few generations due to increasing static power (leakage current). https://en.m.wikipedia.org/wiki/Dennard_scaling

Fascinating, thank you
