If that’s the case you should look into your swappiness settings. You can set this to zero meaning the swap will only be used if you’re actually out of memory, but as others have noted that is maybe not a healthy decision…

Didn’t know that. I agree it is a terrible name, but maybe that’s why it is safe from any cease and desist orders…

Are you maybe looking for something like Revolt or Spacebar?

That is the cheapest option. Maybe the most convenient or most reliable option, but definitely the cheapest.

I am thankful for any input. Maybe it helps someone else looking for a similar thing.

I think the collaborative part means sending PDFs from user to user and maintaining the ability to edit annotations. That may work for many use cases - a lot of businesses may be fine with that when email is still the communication medium of choice.

That’s not an option unfortunately. The actual use case is a non-profit sports club magazine which needs to be proof read by several people at the same time. There is a fixed release date and only a few days to proof read the PDF before it needs to be sent to print.

I have an installation of Stirling PDF, but in my short experiment it had no ability to collaborate on the same document.

Every edit created a new copy of the document downloaded to the user. The annotations weren’t tagged to the individual user and sending different versions of a PDF from user to user is not what I am looking for.

Stirling is a single user software in that regards. I haven’t tested the also mentioned BentoPDF but I suspect it to be the same as it is also trying to be a PDF toolbox like Acrobat. PdfDing has a slightly different approach it might be an option if OnlyOffice does not work out.

I have installed OnlyOffice Community Edition and it seems to work. I need to test it with a few others over a real connection (not just locally), but it seems promising.

I will look into these, do you know if they support collaborative annotations?

You might be right.

Not necessary, no.

I tried that. It opens PDFs in Impress (their PowerPoint) and provides only a very basic annotation interface.

I was wrong. I was using Nextcloud Office not OnlyOffice.

Do you really need that DDoS protection? I have been having my own webserver for decades now hosting public sites and I have only once been in the position that my server was not reachable because of a DDoS attack. And even then the attack was not targeted at my server but at my hosting provider at that time. Everything else was handled by fail2ban easily…

Almost never. I don’t see any benefit .

Gitlab CI/CD pipelines are my go-to tool. At work we self host an instance, for personal projects I use gitlab.com.

That is true for a single person - but in a multiple person household that would mean that everyone needs to carry a copy of their with them. So this mechanism is no replacement for a solid backup of the server somewhere else…

The Bitwarden family plan has been one of the best expenses (if you want to call it that, because it really isn’t that expensive) in our family.

Good to hear. Now buy an external HDD or a device of your choice and copy the files there and store it somewhere safe. One backup is no backup.

You may want to change the title and include the word “protection”…

The traffic is really suspicious. Have you by any chance a health or heartbeat endpoint which provides continuous output? That would explain why so little hits cause so much traffic.
