RMV ticket machine in Wiesbaden: Bad request

I like to take photos of machines where the user interface failed and you can see some details behind it.

This is the upper display of a RMV ticket machine at the Wiesbaden-Schierstein railway station on 2021-08-17:

Bad request on ticket machine

Normally, the upper display shows advertisements and upcoming train departures. We can see that these information are displayed using a website and a web browser running in full screen mode. By the way the fonts look, this should be some Linux system.

Windows Server 2022 in WSUS

We installed our first server with Windows Server 2022. We didn't find Server 2022 as a product in WSUS. After googling, I found out that Windows Server 2022 is listed as Microsoft Server operating system-21H2 in WSUS:

"Mandatory" errors when mail-enabling user

I tried to mail-enable a user, but I got the following error messages:

Database is mandatory on UserMailbox
(In german: Database ist für UserMailbox verbindlich)


ExchangeGuid is mandatory on UserMailbox
(In german: ExchangeGuid ist für UserMailbox verbindlich)

Using ADSI Edit, I found out that the user's msExchHomeServerName attribute contained a value pointing to a server not existing anymore. After deleting the attribute's value, I was able to mail-enable the user.

PCDENotes works with uWSGI

After finding out it works with Gunicorn, I also tested PCDENotes with uWSGI. It works too :)

PCDENotes works with Gunicorn

While PCDENotes (this web application) is provided using Apache and mod_wsgi on this server, I tried to run it with Gunicorn and nginx on my Raspberry Pi. It works :)
