  • I guess it depends on the thickness and the type of clouds? https://www.abc.net.au/science/articles/2012/01/24/3413924.htm

    Cloud factor

    There hasn’t been much research about the effect of cloud and the types of cloud on UV so at the moment the Bureau only gives a maximum clear sky value, and the times of the day when the UV index is expected to be above level three, he says.

    “UV is affected by many things. One of those is cloud, but it depends upon what type of cloud it is, the thickness of the cloud and whether it is deep right through the atmosphere.”

    UV radiation can penetrate through thin cloud, so you can still get high levels of UV at ground level on overcast days, he says.

    Patchy clouds can also intensify UV levels because radiation is reflected off the clouds’ edge.

    "In other words you get a mirror effect and the UV can bounce off the clouds and focus on the ground. You can get quite high UV levels at the ground during partly cloudy days when there are breaks in the cloud.

    “You have to be very, very careful on those sorts of days not to assume you won’t get those sorts of extreme levels.”








  • Each instance is its own server/website but the servers talk to each other.
    People and companies can both host their own instances though I am not aware of any servers owned by businesses.

    If someone shut down an instance all the posts that have already been federated will still be on the other servers that instance has connected to but there will be no new posts.

    The Fediverse in general does have instances owned by companies like how Mozzilla has its own Mastodon server.
    I also think the Owners of wordpress also showed interest in the fediverse though I am not sure if they went anywhere with that.

    This comment is an example of federation since I am from kbin.social but you are from lemmy.world yet I can see your post and comment on it.




  • True this is only a temporary fix so there is less spam until we get proper moderation.
    I actually thought the post didn’t work when I first posted it because it did not show up due to the filters.

    Using these filters combined with blocking /m/internet didn’t block all the spam but made it more tolerable for me.
    The only other options that I can think of is it report spam or apply to be a moderator.

    I agree though we need proper moderation.
