Variable name	Description

Enable PipeWire on Ubuntu 22.04

This guide is only for original Ubuntu out-of-the-box packages. If you have added a custom PPA like pipewire-debian, you might get into conflicts.

Ubuntu 22.04 has PipeWire partially installed and enabled as it's used by browsers (WebRTC) for recoding the screeen under Wayland. We can enable remaining parts and use PipeWire for audio and Bluetooth instead of PulseAudio.

Starting from WirePlumber version 0.4.8 automatic Bluetooth profile switching (e.g. switching from A2DP to HSP/HFP when an application needs microphone access) is supported. Jammy (22.04) repos provide exactly version 0.4.8. So, we're good.

Based on Debian Wiki, but simplified for Ubuntu 22.04.

Web Design Contract

Based on Contract Killer, an open-source contract for web developers.

Summary:

I’ll always do my best to fulfill your needs and meet your expectations, but it’s important to have things written down so that we both know what’s what, who should do what and when, and what will happen if something goes wrong. In this contract you won’t find any complicated legal terms or long passages of unreadable text. I have no desire to trick you into signing something that you might later regret. What I do want is what’s best for both parties, now and in the future.

So in short;

You ([CLIENT COMPANY]), located at [CLIENT ADDRESS] are hiring me ([DEVELOPER]) located at [DEVELOPER ADDRESS] to design and develop a web site for the estimated total price of [QUOTE] as outlined in our previous correspondence.
