I have never met anyone refer to "screen off" as "sleep".
https://en.wikipedia.org/wiki/Sleep_mode
The terms everybody else are using are: "sleep" = "suspend to RAM" = "S3" and "hibernation" = "suspend to disk".
Keep in mind that a part of the filesystem will be reserved on creation. Here if I create a completely empty ext4 filesystem with:
truncate -s 230G /tmp/img
mkfs.ext4 /tmp/img
mount /tmp/img /mnt
Dolphin reports "213.8 GiB free of 225.3 GiB (5% used)"
Thanks, that sounds like the ideal setup. This solves my problem and I need an APT mirror anyway.
I am probably going to end up with a cronjob similar to yours. Hopefully I can figure out a smart way to share the pool to avoid download 3 copies from upstream.
Using scheduling is not a good option IMO, it's both too slow (some machines will wait a week to upgrade) and too fast (significant part of machines will upgrade right away).
It seems that making APT mirrors at the cadence I want is the best solution, but thanks for the answer.
Making multiple mirrors seems like the best solution. I will explore that route.
I was hoping there was something built into APT or unattended-upgrades, I vaguely remembered such a feature... what I was remembering was probably Phased Updates, but those are controlled by Ubuntu not by me, and roll out too fast.
So you can test the updates before fixing production.
My question is how to do that with APT.
No, I'm asking how to have unattended-upgrades do that.
... and feel endless pain from whatever they did to the scrollbars. Seriously, wtf.
I don't know, I recently got a 2-in-1 laptop, and was surprised to see that KDE works great. Got Onboard as on-screen keyboard. Screen rotation works great. Glad I didn't have to run Gnome on that machine.
How many real teachers per student though? Is this just an excuse to have even less human support, because "we have 10 AIs per student"?
What does a ratio even mean in this case, the AIs are not separate.
For whatever reason, to this day I get a 403 error on http://google.com/ from IPv6. https://www.google.com/ works through.
Sometimes it's not your side that is broken.
Exactly this. Services and software are not the same thing, you're asking for a service recommendation and it can't be open-source software because it's not software.
