Microsporidia form spores which could be released en masse to infect mosquitoes Male mosquitoes (which don’t bite) could be infected in the lab and released into the wild to infect the females when they have sex
GPU price per FLOPS
in recent years, GPU prices have fallen at rates that would yield an order of magnitude over roughly:
17 years for single-precision FLOPS
10 years for half-precision FLOPS
5 years for half-precision fused multiply-add FLOPS
Jukebox
We’re introducing Jukebox, a neural net that generates music, including rudimentary singing, as raw audio in a variety of genres and artist styles. We’re releasing the model weights and code, along with a tool to explore the generated samples.
Dead drop drugs
Most Russian drug dealers don’t hand off drugs anymore—they stash them in geotagged hiding spots ready for pickup by online buyers.
Solar System Black Hole
A possible alternative is to probe the gravitational field of this object using small, laser-launched spacecraft, like the ones envisioned in the Breakthrough Starshot project. With a velocity of 0.001c, such spacecraft can reach Planet 9 10 years after launch and can discover it if they can report timing measurements accurate to 10^-5 seconds back to Earth.
