&gt; I took 828 and really enjoyed it. It was one of the best classes I took at MIT. The other OS for that class is JOS, which is the one you build through the labs. It&#x27;s similarly simple to understand and not that long to build.<p>I&#x27;m not sure what I&#x27;m supposed to take away from your comment aside from &quot;I went to MIT&quot;.
