I spotted a few things.<p>1. Class 828 was a really good class, best he took. Others might want to try it too!<p>2. There&#x27;s another operating system that&#x27;s used in the class called JOS you might like to check out also if you are into learning about operating systems.<p>2. b) JOS is similarly quite simple to understand and doesn&#x27;t take that long to build. Try it out also.<p>Hope this is helpful!
