Getting Teams to Work on Ubuntu

There's an issue getting the microphone to work out of the box on Ubuntu 20.04 and teams.  The microphone works but NOT the internal microphone.  It has to due with security and it seems like it's using the default browser's security settings.  The solution for now is to start Teams with sudo.

Create a Menu Entry for Teams as Sudo

Refer: https://www.tecmint.com/run-sudo-command-without-password-linux/

Allowing sudo for a program without a password

$ sudo visudo

At the end of the file, add the following, and save it:

mruckman ALL=(ALL) NOPASSWD: /usr/bin/teams

IntelliJ Optimize Imports

Update: in IDEA 13 "Use single class import" does not prevent wildcard imports. The solution is to go to Preferences (⌘ + , on macOS / Ctrl + Alt + S on Windows and Linux) > Editor > Code Style > Java > Imports tab set Class count to use import with '*' and Names count to use static import with '*' to a higher value. Any value over 99 seems to work fine.
