If you're replacing all of O365 (excellent choice, BTW), I do recommend Nextcloud with a few plugins. I use it specifically for sharing contacts and calendars among my family.
LibreOffice is my desktop word processor and spreadsheet, and I use it more than OnlyOffice, but if you need two people in the same file at the same time, OnlyOffice is a better option.
If you're (going to continue) using Office 365, you can use Evolution as an Outlook replacement. Evolution EWS rides OWA and ActiveSync protocols to give you email, calendars, contacts, notes, etc. I've used it for over a decade. It works very well once setup.
As for Android, there are several, including Outlook for Android (which is bloated and slow, being a Microsoft product), which I am forced to use because of our company SSO config.
If you're looking for an Office 365 replacement, I use Nextcloud for my personal stuff. It has files, contacts, calendars, notes, etc. If you install the OnlyOffice plugin, you get multi-user online document and spreadsheet editing. I use the DAVx5 connector to get (shared and personal) contacts, calendars, and tasks in my Android phone. It integrates into the environment so all calendars and contacts apps work automatically. It also automatically backs up pics/vids I take with my phone automatically.
This is the way.
Now that it's up, make sure it's secure. Then work on mail deliverability (if that is a goal).
If your requirement is a 3.5" drive bay, then maybe check out some of the SFF form factors, like an HP Elitedesk SFF 800 (not the mini/micro). It has the same hardware as the mini, takes the same amount of power, but has a space for a 3.5" disk and a slimline optical disc. It's bigger than a NUC, but smaller than a tower.
Are you seeing posts from those communities since you subscribed? If so, it's working.
I recently left/rejoined several communities due to something like this. I think it's just a display bug, but I can't confirm now, due to the above.
I still use E16 for my WM on my main PC. It's got some quirks, but I like it's light resource usage (by modern standards), quick startup times, and the theme I run.
E17 is stuck in perpetual dev pergatory like Hurd.
I did too until I tried to use them. They lack several features that rooted containers have, and a lot of howtos take for granted. They're fine for very simple containers, but expect pain an suffering.
Until and unless IBM changes the deal, no.
Fedora is leading edge, rolling-release (more or less) Linux distro that IBM bases RHEL from periodically. Fedora has always been allowed to play with new technology and ideas (Wayland, btrfs, etc), while RHEL is about stability and long support cycles.
It probably didn't. What's probably happening is that when Debian starts, it loads power management, while being in the BIOS/UEFI still has everything at max.
You should be fine for PCI compliance as long as you are on a current release (Been there already, a few times). Also AlmaLinux already has an Announce mailing list ([email protected]) where they release update notifications (including Security releases) just like CentOS did.
Just wait till they bring it back, now powered by Chat GPT!
From the top of my head, compared to ext4: RAM use and the ability to shrink an FS if necessary. Oh, also I've used an EXT FS driver on a Windows host, but I've never seen one for XFS.
