Manually spin up and manage a meaningful local Spark cluster (say at least 1 master node with 8+GB and 3 worker nodes with 4+GB memory), build a data pipeline (don't care to much about the analytic things, I'm more into parsing tons of JSONs) and parse a meaningful number of JSONs (say 10GB at least) and optimize the parsing algorithm. Low level computing. I purchased a kit and prepared to register a coursera embedded class. I also want to learn Windows system programming especially those related to Malware analysis (How does VM in OS work? What does a process contain? How to hijack a process? How to write shellcodes? These kinds of things). Cold war politics and military-intelligence history. I got attracted to this field years ago after watching Godfather 3 and searched a bit about the background story. I know a few buzzwords but don't really have the $$, language capacity and time to drill deeper. Mainframe. I didn't manage to register the IBM event this year, so it has to wait until 2022. Sigh, too much to learn and too few time.
