Besides RAM, what resources do you think you’re saving? Not CPU cycles or IO ops, because you’re processing the same amount of DB queries either way. Not power consumption, since that isn’t affected by RAM utilization. Maybe disc space? But that’s even cheaper than RAM.

Or more importantly: the extent to which you can self-host out of sheer luck and ignorance like you suggest is very limited. If you don’t want to engage with a minimum amount of configuration, you might bump into security issues (a much broader and complex subject) long before any of the above has a material impact.

You’re mischaracterizing what I said. My point is that running multiple DB processes on a server isn’t going to have a significant impact on system load, if all other factor are kept constant.

You seem to be obsessed with optimising one resource at the expense of others. Time is a limited resource, and even if it only takes 5 minutes to configure all of your containers to share a single db backend (it will take longer than that even if you just have 2), you’re only going to save a few MB of RAM. And since RAM costs roughly $2.5/GB (0.25 cents/MB) your time would have to be worth very little for this to be worthwhile.

On the other hand, if you’re doing it to learn more about computers then it might be worthwhile. This is a community of hobbiests, after all…

Neither, I’m trying to explain that you don’t need to know the implementation details of the software running on your server to backup the entire thing.

Where are you getting that from? The fastest and easiest way to back up any server is a full filesystem backup, especially if you’re using something like zfs or btrfs.

I’m saying this based on real world experience: after a certain point you start to see deminishing returns when optimizing a system, and you’re better off focusing your efforts elsewhere. For most applications, customizing containerized services to share databases is far past that point.

Do you have the data to back that up? Have you measured how much of an impact on system load and power consumption having 2 separate DB processes has?

Roughly the same amount of work is being done by the CPU if you split your DBs between 2 servers or just use one. There might be a slight increase in memory usage, but that would only matter in a few niche applications and wouldn’t affect environmental impact.

For most applications the overhead of running a second DB server is negligible.

I write software for a living, and have worked with all 3 database options in the past. I don’t know what DB backend my nextcloud server is using, nor do I care.

There are a lot of highly paid software devs who started with no connections or college degree. This might be the hardest time to enter the field as a junior, but it’s definitely not full of nepo babies. You must be thinking of finance/law.

Is this what they call FAFO?

Not entirely true… If you write libraries for other developers you can use them as beta testers. Your customers have a production environment, but you don’t. At least, that’s what one of our vendors seems to think…

If they send 2 emails per subdomain per year, that could easily be 10s of millions which would make the cost per email measured in thousandths of a cent. And I could see the number of subdomains being larger by a factor of 10, maybe more.

Another angle: someone with IT experience needs to manage the system that seems emails, and other engineers need to integrate other systems with the email reminder system. The time spent on engineering could easily add up to thousands per year, if not tens of thousands.

I’m guessing their figure is based on both running costs and engineering costs.

If you have a spare pci-e port you can get a card that adds a USB controller. Some m.2 ports also have a pci-e channel you could use with an adapter.

LetsEncrypt is a good option if you want to set it up yourself. More work than cloudflare though.

And you lose access to “your” site if they go out of business. Sounds a lot like renting, not sure where the “ownership” part comes in.

The vulnerability was discovered during a pwn2own competition. The competition was endorsed and probably sponsored by Synology. Not sure what the problem is?

OP: asks for advice about IRC

just_another_person: only stupid and lazy people use IRC

…

just_another_person: why doesn’t anyone appreciate how helpful I am?

Quoting my previous comment:

Why move an entire community to matrix if IRC works fine?

In other words, why “fix” it (and risk fragmenting the community) if it ain’t broke?

If you still don’t understand why people use IRC then we clearly didn’t make the same point, and you misunderstood mine.

People still use it for the same reason we use email… Why move an entire community to matrix if IRC works fine? Anyone who wants to use matrix can set up a bridge, anyway. And I wouldn’t consider discord a good alternative.
