  • Thanks! It seems this is the same study. It seems the specifics are that insects are not directly attracted to the light, rather they expect a diffuse light source overhead (such as from the moon and stars) and use this to orient themselves. Their primative light detection can’t tell the difference between this light and artificial light.

    I would say this is more an explanation of how insects confuse artificial lights for moonlight, I wouldn’t say it disproves the idea that insects confused artificial light for moonlight.




  • Yeah, possibly. But also they may have collected more evidence in the meantime.

    I’d also bet a fair bit of money that the police don’t have the resources they need to fully investigate. It sounds like the police might have got more evidence later, too. This part:

    The next day, in the early hours of 2 March, the man allegedly destroyed hundreds of plants at a commercial nursery near Motueka, after entering the property on his motorbike and allegedly destroyed the CCTV camera when he noticed it, the police summary of facts says.

    On advice from friends, colleagues and contacts within law enforcement outside the region, Reese went back to the police.

    What was she bringing to the police? Is she linked to the nursery or is this sentence a separate statement saying she talked with the police some more about the initial break in?


  • Uhh, what the fuck? How did anyone think letting this person go was a reasonable thing to do?

    It’s hard to say since they won’t release the details to the media, but I’d say most likely it seemed reasonable at the time. For example, perhaps he had medication that was controlling his delusions and hadn’t done something like this before, but for some reason he stopped taking the medication. In this case, it may be reasonable to release him so long as he takes his medication. He doesn’t, so he ends up back in court with compulsory treatment.

    Schizophrenia affects an estimated 0.3-0.7% of the population at some point in their lives. There are different symptoms so not all incidents are like this case, but we are talking 15,000+ people in New Zealand. The court likely sees similar things a lot, and many, maybe even most, would not have any further incidents.

    It’s crap that this happened but I think I’d give the judge the benefit of the doubt.



  • I find this bit a bit confusing.

    Contrary to myth, nocturnal insects do not fly around artificial lights because they confuse them with the moon or stars. Recent research, filming moths with high-speed cameras, found they use moonlight and starlight to differentiate between “up” and “down” as they fly.

    Their erratic flight around your outside light is actually due to them trying to orientate themselves to a nonexistent horizon.

    I don’t quite get the difference between insects confusing lights with the moon and stars vs using them to orient up and down, which presumably is due to them being like the moon or stars so they can tell which way is up.

    It would be nice if they actually described how this research identified what makes them confused, or explained it a bit more.

    Also, do inside lights affect insects when curtains are shut (which largely block the light), or is it mostly outside lights and street lights?


  • It was actually to do with docker rather than postgres itself. Docker limits shared memory to 64MB, and postgres died when it couldn’t allocate more. I saw this in the test server as well, but I didn’t want to assume so I waited to see it in production before applying the fix.

    The error was something about failed to allocate disk space, the solution was to add shm_size: 1GB to the docker compose section for lemmy’s postgres.

    This says there are fat naked mole rats, but it says their role is to connect to other naked mole rats communities by digging when the ground is soft from rain. That’s quite different from the claim that their role is to block the tunnels to stop them flooding.

    Not OP, I couldn’t find a paper. Just this site that makes the same claim almost word for word, and cites a youtube video of a lecture at Stanford. I didn’t watch the video, but this seems best described as a “plausible” explanation rather than a proven fact.


  • Here’s a photo I took recently:

    photo of sunset over river with trees on far shore of river, sun setting behind trees - sun low but a yellow not red sky

    I think we should make themes optional so if you have a pic you want to post that doesn’t fit, you still can, what does everyone else think?

    I think this is a good idea. Got something cool to share? Just share it. Prefer the challenge of a theme? We got you covered.





  • It makes me think of waves breaking on the shore. Perhaps the old route out of Wellington with the road next to the sea and the waves that sometimes broke over the wall onto the road. The green is like an ominous stormy sky from a story book, and the darker bit between the lighter top and the waves at the bottom is like the swell of the sea. There’s probably a monster in the water.
