Assembled from various bits in [WayBack] How do I change the hostname without a restart? – Ask Ubuntu.
Assume your new host name is newHostName.
- edit
/etc/hosts and replace the old hostname with newHostName
- Perform these commands:
hostnamectl set-hostname newHostName
exec bash
hostname -f
Both the command prompt and the hostname output should show newHostName.
Note: if you get this when performing hostname -f then you forgot to edit /etc/hosts as per [WayBack] Just so everyone knows, the edit of /etc/hosts did the trick the 12.04 – Why I get hostname: Name or service not known error? – Ask Ubuntu:
hostname: Name or service not known

[WayBack] What happens when a huge number of people share a single grocery store loyalty card? – The Old New Thing
An interesting discussion in the comments besides this interesting article observation:
What messes up their data analysis is when two people with different lifestyles swap cards. The system sees that somebody who used to buy yogurt and bulk brewer’s yeast is now buying potato chips and frozen pizzas, and it can’t figure out what is going on.

Hopefully the next few years will finally show what the incremental software development and evolutionary management has been trying to advocate since the late 1950s and 1970s: hierarchies do not work and purpose works better for the vast majority than being in a triangle.
The first slide below is from Thoughtworks who has been doing these changes for several decades now.
Traditional hierarchies are giving way to more open and creative workplace cultures.

That’s the only way to cope with complexity as talent dilutes in growing organisations.

It looks like when syncing folders between Mac OS X (MacOS X?) and Windows, many directories get empty Icon? files have a size of 0 bytes.
None of these directories had custom icons, so I’m inclined to remove them all from the Google Drive folder:
find . -name 'Icon*' -size 0 -print0 | xargs -0 rm
as [WayBack] Didier Trosset answered at [WayBack] How to delete many 0 byte files in linux? – Stack Overflow
Before I do that, I need to read these in more detail:

This is not what you like when you reboot a VM in Proxmox:
Booting from Hard disk...
Missing operating system

Booting from Hard disk… Missing operating system
This case was a Windows 7 UK Professional x64 SP1 virtual machine.
Luckily the ISO is at https://archive.org/download/en_windows_7_professional_with_sp1_x64_dvd_u_676939_201606/en_windows_7_professional_with_sp1_x64_dvd_u_676939.iso via https://archive.org/details/en_windows_7_professional_with_sp1_x64_dvd_u_676939_201606 (later I found out I had the image in my backup vault as well).
I put that one in /var/lib/vz/template/iso so proxmox will automagically provide it in the local storage of iso images.
Now for some screenshots some based on what I learned at [Archive.is] How to use System Recovery Options for repairing Windows Vista or 7 installations:
