Overview

The issue concerns the behaviour of Excel's RTD feature when:

the RTD call is made from a wrapper function,
the wrapper function is called from an array formula, and
in one of the calculation calls, the wrapper function does not make an RTD call.

The expected behaviour is that the RTD server gets a DisconnectData call for the relevant RTD topic.

The observed behaviour is that the RTD server does not get a DisconnectData call.

Installation Notes for pipenv on Ubuntu 18.04

1. Add `~/.local/bin` to `PATH`

pypa/pipenv#2122 (comment)

echo 'export PATH="${HOME}/.local/bin:$PATH"' >> ~/.bashrc

Run regedit.exe elevated.

Rename the RunAs value to _RunAs.
Create a new shortcut on your Desktop for C:\Windows\System32\runas.exe.
Name it something like Admin-Explorer.
Right-click the new shortcut and click Properties.
Change the target to: C:\Windows\System32\runas.exe /noprofile /user:<domain>\<username> "c:\windows\explorer.exe /separate"

How to set up PulseAudio over Network

PulseAudio actually has great networking capabilities. Especially when combined with Avahi/Zeroconf it is especially easy to set up, though technically it should also be possible without.

Setting up the server

Open /etc/pulseaudio/default.pa
At the end of the file, add load-module module-native-protocol-tcp auth-ip-acl=127.0.0.1;192.168.254.0/24 auth-anonymous=1 to activate networked audio from 192.168.254.0-255 without needing authentication.
Kill pulseaudio, it should be auto-restarted, or restart your login session to activate the changes. You should now be able to set PULSE_SERVER=192.168.254.XXX and have the remote audio working! If not check the firewall settings, PulseAudio seems to open a random port by default.

Setting up automatic configuration and discovery

On both the server and client, install pulseaudio-module-zeroconf and avahi, then after installing make sure Avahi always runs by running systemctl enable --now avahi-daemon
