Hawaiʻi has the largest single integrated Outdoor Siren Warning System for Public Safety in the world. The all-hazard siren system can be used for a variety of both natural and human-caused events; including tsunamis, hurricanes, dam breaches, flooding, wildfires, volcanic eruptions, terrorist threats, hazardous material incidents, and more.
They test them here every month too. Shameful they didn't sound them when needed the most.
Ska 'za? Nah brah.
Yeah probably true. I only thought to look it up because I knew active and passive sonar was a thing.

No idea about your algorithm problems but have you seen the Cutting Edge Engineering Australia channel? It's so good.
The wikipedia article Polydactyly in stem-tetrapods has some explanations on how we ended up with 5 fingers and toes.
The gist of it is that tetrapods (four-limbed vertebrate animals) evolved from a fish similar to a lobe-finned fish that had 5 sets of bones in each of its fins that evolved into fingers and toes. Some tetrapods have subsequently lost digits but the basal state was five.
There's a book, Your Inner Fish by Neil Shubin that's full of this kind of stuff. Highly recommend.
