Is being underwater nature's low-pass filter, sort of like the natural audio equivalent of visual blurring?

    I'm going to take a guess at the observations that have lead to your questions.

    Above water sounds are muffled when one is underwater. This is due to an impedance mismatch between two mediums, air and water. When airborne sound encounters the surface of the water, only a small fraction of that sound continues to travel through the water, the rest is reflected off the water's surface.

    Similarly, our ears and vocal cords have evolved to be efficient transducers above water, but not when submerged. On the other hand, whales have evolved very efficient underwater transducers and can communicate with other whales over 100s, maybe 1000s of miles/kilometers. They typically communicate at low frequencies since attenuation increases with increasing frequency. This is similar to what happens in air, like when comparing thunder from a distant lightning strike to a strike that happens nearby: the distant strike sounds like a deep rumble since the mids and highs have been absorbed by barriers and the air while the nearby strike results in much more high frequency "crack" and "sizzle" sounds.

    Just riffing over here. Sound is rad.

    I beat Metroid: Zero Mission a few weeks ago (that's probably the 7th game I've completed in 30+ years of gaming hahah) and I'm thinking of going through the rest of the series.

    Any good bags that don't require rack/bracket?

    A backpack and some paracord can be an effective solution. Learn a few basic knots and find some spots you can attach to...you can have a secure bag on the bike and a comfortable bag off it.

    Not a dev nor a privacy/security expert, but if you've had issues with system updates breaking stuff, I'd steer clear of Fedora and roll with something a bit more stable and consistent, like Debian or Ubuntu LTS releases. The 6-month system upgrade cycle is pretty onerous with Fedora.

    I was gifted that game and between my rapidly falling temperature and hunger and my poorly coordinated attempts at stunning baby rabbits, just gave up about 15 mins in. Is it worth it to give it another shot? I've tried twice now...

    There could be three, four, seven, or twenty parties and you could vote for the candidate that best represented your ideals and they could stand a reasonable chance of being voted into office if we would just embrace ranked choice voting.

    I dig the styling and pricing of those REs, but my mechanic warned me that getting parts from India can be tricky or take a long time.

    How dangerous is it really?

    It is crazy, but you still see cats out there on liter bikes in visors and flip flops. Totally nuts.

    My problem was a fully reactionary sudden application of the front brake when I heard the squeal ahead of me. In a car, no prob. On a bike, bad idea. Locked the front tire and it was game over. Instead, I should have either progressively applied brake or just had an escape route in mind. Both are techniques that every course or vid or book will tell you, but its not until you build up that muscle memory that you'll for sure properly apply the right technique at the right time.

    Good luck and ride safe!
