Interesting tor based async messaging server/protocol, sorta the encrypted equivalent of email without leaking too much metadata.

Sounds a little like they are pushing some link layer information up into the TCP stack, breaking the OSI model a little...

Interesting wind turbine design, basically gives up on trying to capture energy from the center, and tries to capture tip shedding vortexes. Also it may not be obvious but it appears to use diffuser rings and is swept forward so air gets funneled towards the center, but the center hub cone forces the air back out towards the edges, possible increasing local velocity. A little surprising they don't fair the backside of the hub. Appears to use active tracking rather than a passive guide vane. Weight is an issue for a ringed fan design like this, so it won't scale up to megawatts, but since their target is quiet operations in residential areas, that isn't such a big deal.

Vanish Installation and Configuration
A system that uses a p2p network to store ephemeral encryption keys, so that an encrypted message can be decrypted within 8 hours of encryption, else the keys are lost forever. This obviously does not prevent someone from saving a plaintext copy of the decrypted message, but for practical purposes this is a self destructing message. I suppose if someone tried really hard, they could try to collect all keys from the network constantly and time reference them, then try a brute force attack using a limited key set.
