<p>The standard documentation for Ubuntu or debian below all works, but you should first skim the
<a href="../computing/winlaptop.html">Windows expo laptop</a> configuration too. So far as expo software is concerned, WSL1 and WSL2 behave identically.
<h3>Why no Docker container?</h3>
<p>Yes, it is true that this would greatly speed up on-boarding new programmers.
<p>But there is the significant danger that containers would get copied around and deployed without being properly cleaned up: resulting in configuration drift and a <a href="https://martinfowler.com/bliki/SnowflakeServer.html">snowflake server situation</a>. File permissions are a big issue.
<p>We should do both: create a Docker system for getting started, then transition programmers to script-based or recipe-based provisioning so that systems are rebuilt cleanly. CUYC (who also use Django) have a bash script which sets up a new django development system. We should copy that in the first instance. Alas, we haven't got around to doing any of this yet.
