LET THERE BE GERMICIDAL LIGHT: THIS $500 FIXTURE COULD STOP THE NEXT PANDEMIC, FROM COMPLEX SYSTEMS

Far-UVC 222 has been shown to efficiently inactivate airborne pathogens in a room-sized chamber. While the technology is unlikely to prevent the average common cold, mostly spread through close, extended contact, it could be helpful in blunting a future respiratory pandemic where more of the spread happens at a range through shared air. It is functionally equivalent to an extremely strong air purifier. The biggest bottleneck to the technology's adoption currently is awareness.

NO PLAN SURVIVES CONTACT WITH THE ENEMY (REALITY)

A QUICK LOOK AT ZERO-KNOWLEDGE PROOFS

The idea of a zero-knowledge proof (ZKP) is that there are two parties: the prover and the verifier. The prover asserts that it has a solution to a (generally NP-complete) problem. The prover can convince the verifier of this without sharing the actual solution to the problem. While they are used to secure some cryptocurrencies, that is not their only use case. This article looks at how ZKPs work and how they can be applied to other problems like age verification.
