Probably a dumb question but about tonights (or last night) lunar eclipse. in c/space@lemmy.world
[–] young_broccoli@fedia.io 2 points 1 month ago

Got it, thats very interesting. I already understood the redness of the shadow but had no idea how much more complex it is and that picture of earth eclipsing the sun makes it way more clearer.

Thank you very much, I would upvote you 10 times if I could.

So like the umbra has a "bright" edge compared to its center?

I think that was my mistake, I was thinking of the transition between the penumbra and umbra had a straigt edge when viewed from earth.

thanks

I knew about what causses the moon to appear red but I never really thought about sunsets/rises beyond "its the atmosphere refracting light". That was a very nice explanation about them. Thanks.

I think it does. Thanks.

So in other words; That side of the moon is closer to the edge of earths shadow. Correct?

I get that, but if the moon is completely behind the umbra of earths shadow why is that it looks brighter on one side/edge?

Examples:

Eclispe 1

Eclipse 2

Eclipse 3

Not my pictures btw. I took them from r/astrophotography

If its a total lunar eclipse why does one edge remains brighter than the rest?

I have been googling for an answer for a while and cant find it. Even pictures of previous total lunar eclipses are the same. Is it because that side remain closer to the edge of the umbra? Or is it caused by how light behaves; Or because the surface of the moon is more reflective on that part.

Looking for help/guidance on how to setup a server for a business (fedia.io)
 

Hi. Some friends of mine are starting a business and they want to setup a server to host a simple "contact" website, run an e-mail service (about 10 accounts for now but with possibilities of expanding it to support more) and to store and remote access documents.

Im a computer savvy person so they asked me for help, but dont know much about self-hosting so I come here asking you:

What kind of hardware do they need and would be best? What OS and other software is required and recomended?
How to set it up/configure it? Im partial to foss but if there are good propietary options they are acceptable too. And last: What do we have to watch out for or avoid.

Also, space is a bit of an issue, I was thinking they could use something small like an intel nuc but Im worried that hardware would be underpowered for their needs.

I have been googling for stuff myself but I get overwhelmed by the ammount of information and some contradicting opinions so I appreciate your recomendations and guidance. Im not asking you to give me a full tutorial, although I would appreciate it too, but just to be pointed in the right direction to avoid, as much as possible, spending money and time on things they might not really need or might not perform as well.

Thanks in advance.
