    Author here. This! The point isn't to name and shame, but to illustrate a complex failure mode. I too could see myself writing this bug!

    The site's description says: "I was feeling nostalgic for the Windows Bubbles Screensaver, so I made my own, much more relaxing version." Click the bubbles and they pop! Very satis…

    I'm sure of it. And yet based on this rapidly getting to the front page, it seems like many of us are part of today's lucky ten thousand: https://xkcd.com/1053/ Might be more than …

    (Author here) The image is AI generated. I did not use any AI to write the post itself. That's just my style of writing, you can check my pre-GPT posts and compare if you'd like.

    Haha sadly from reading many of the rest of the comments, the typical HN reader seems unconvinced that trees or rain could impede Wi-Fi signals, because their Wi-Fi at home goes th…

    Wow! Are you maybe able to find a demo video of this? I'd love to see it! (I'm the author of the post btw)

    Related, sure! But it could be rain helping close a circuit on a rusty antenna connector port. Or rain improving the grounding of some neighboring circuit that otherwise drains thr…

    (Author here) For our Wi-Fi bridge, the devices on both ends were set to max power. I don't recall them being able to change data rates very much (if at all) because the ones at th…

    Right. This is a multiple timelines problem. This story happened a bit over 10 years ago at this point. At the time of the story, the Wi-Fi bridge was already almost 10 years old -…

    Even if you are looking at the turbines "edge-on," there's probably going to be a noticeable Doppler return as well. Plastic drones with plastic propellers are still visible on rad…

    (Author here) I didn't forget, it just didn't seem like the most likely problem. Like I said in a reply to a sibling to your comment, the gear was ~10yrs old at the time and had be…
