What happens when a huge number of people share a single grocery store loyalty card? – The Old New Thing

[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.

Is the era of management over? | World Economic Forum

Posted by jpluimers on 2018/01/12

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.

Reminder to self: Sort out empty (zero size) Icon? files in Google Drive folder on OS X and Windows

Posted by jpluimers on 2018/01/12

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

Before I do that, I need to read these in more detail:

Proxmox – recovering a Windows 7 machine having “Missing operating system”

Posted by jpluimers on 2018/01/12

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

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.isHow to use System Recovery Options for repairing Windows Vista or 7 installations:
