• I have a question.  As a fairly new programmer how do you best deal with variables changing types and being cast wrong in languages like python (what im working on).  In C it was fairly easy either its the right type all the time or it fails miserably and you didn't have random "its a NoneType this time" errors other than doing a ton of if loops checking for it
• McGee (Discord)
• I’m taking a class this semester called Operating Systems. In this class we will be creating a basic operating system in C and apparently some Assembly... what are some things to keep in mind or to expect when writing something like this?
