    My hypothesis is that the freezer motor has to be right at the freezing point and the tray has to have few nucleation points such that when a small spek of water freezes the phase change disperses enough heat to prevent them from immediately following suit, the small flake of ice then rises to the surface. As it continues to cool, further freezing is more likely to occur in the existing crystal. Through a combination of ice’s buoyancy and the surface tension of liquid water, the crystal gets pushed upward compared to liquid water.

    I wonder if the fridge motor’s vibration plays any role on where the fingers form (due to resonance patterns).








  • Because the tech industry hasn’t had a real hit of it’s favorite poison “private equity” in too long.

    The industry has played the same playbook since at least 2006. Likely before, but that’s when I personally stated seeing it. My take is that they got addicted to the dotcom bubble and decided they can and should recreate the magic evey 3-5 years or so.

    This time it’s AI, last it was crypto, and we’ve had web 2.0, 3.0, and a few others I’m likely missing.

    But yeah, it’s sold like a panacea every time, when really it’s revolutionary for like a handful of tasks.

    Right? Like half of what I want from these things is when is the battery low? When is the outbox full? When is the feeder empty? And metrics to verify the device is generally operating safely.

    Controlling the device? We’ve known how to do that for 50+ years. Help me maintain the device.
