Samsung laptops using the samsung_laptop driver have a feature called
'battery life extender', basically a fixed stop charge threshold at 80%.

This script can be used to backup essential configuration files from the Proxmox Virtual Enivronment (PVE) host.
The script will create backups using tar with specified backup prefix and date and time stamp in the file name. Script will also delete backups that are older then number of days specified.
To create backup script that will be executed every day we can create backup script in /etc/cron.daily/ folder. We need to make it writeable by root (creator) only, but readable and executable by everyone:
touch /etc/cron.daily/pvehost-backup

| Reverse Engineering the Apple Airscan / eSCL Protocol | |
| I am not certain of the origins, one person involved in IPP printing claimed it was proprietary of HP , but then again they have their own protocol. AirScan/eSCL is used by other manufacturers too like Xerox, Kyocera, Canon and more. Mopria also seems to claim some responsibility for it but then again it seems not completely. In any case it seems shrouded in such secrecy that to date several years after its implementation, unless someone wants to take it all apart. | |
| I offer this as my contribution. It is not perfect but almost there. | |
| As I began looking for information to make a scanner more compatible, I could only find fragments of information. Even Apple Developer Forums offered zero help. | |
| Server/Client in eSCL / AirScan: | |
| There is a “server”and a “client” the client can be a desktop computer or mobile device. The server is a scanner or another device configured to emulate a hardware scanner, even a desktop computer. In my case I did this on Linux, so |

I just got this working so I figured I'd share what I found, since there's hardly any information about this anywhere online except an RFC, the GPG mailing list and one tutorial from the GnuPG blog.
You can use automatic key discovery with WKD (Web key directory) to make it easy for users to import your key, in GPG since version 2.1.12. Since this feature is fairly new, it isn't yet available in the current LTS release of Ubuntu (16.04; xenial), however it is available in Debian stable (stretch).
I couldn't add a DNS CERT or DANE / OPENPGPKEY record through my email service (which also hosts my nameservers). I tried making the PKA record - a foo._pka.example.com TXT record but GPG doesn't seem to recognize it and fails; I'm still investigating why.
So the last option for self-hosted auto-discovery was WKD.
First thing I had to do was add an email address to my key. My primary UID is just my name so the key represents my identity rather
