It's not self-cancellation in the way you're interpreting the title :)

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!

Hi! Author here. You're right — but two things to consider here. First, that quote is referring to human-made systems, not natural ones (as is the rest of the essay!) and I think our views align on whether human systems regularly work.

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 satisfying :)

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 ten thousand, even, based on

The shell script starts with the following comment: # All the code is wrapped in a main function that gets called at the # bottom of the file, so that a truncated partial download doesn't end # up executing half a script.

Seems like another user with way more experience than me did an excellent job explaining the situation -- I enjoyed reading their answer!

Oh wow, what a read! Great story, thanks for sharing :)

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 through walls just fine. A few even suggested I shouldn't

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 through the metal scaffolding the antenna is attached to. Or ra

(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 the beginning of the story were 802.11g devices, and 802.

by obi1kenobi 2y ago
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 -- we'd had the same equipment since I first remember ge

(Author here) Across several city blocks, in fact, and longer than the max range of Ethernet on normal (Cat 5/5e/6) cables. Past ~300ft/100m, you need a repeater even for Ethernet. We would have needed at least one repeater s

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 radar because the tiny propellers spin super fas

(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 been working fine until then. It was perched in a ve

(Author here) I didn't think to check the line of sight because I was primed by the fact the bridge had been running fine for 10 years. With networking gear that old, it seemed more likely that a device/cable/power brick had

(Author here.) Yeah, I get where you're coming from. Ultimately, this was an editing decision first and foremost. Beamforming is cool and magical, and MIMO even more so. The post wasn't intended as a primer on wireless technology,

(I'm the author.) I really like trees! So I wouldn't have wanted to cut it down or even prune it. Also, I hate operational (ongoing) solutions to problems. Pruning it would have been exactly that kind of solution -- we'd have

No antenna is directional enough to overcome n^2 scaling. Especially not the mid-tier consumer-grade hardware I would have had access to at the time. Rough rule of thumb, a consumer-grade directional antenna (at least at the time, maybe the
