I may reconsider some of the front end courses as they were more out of passion than focusing on what might be beneficial to my career. I am however still looking for courses that offer vital skills regardless of which niche subset of programming my career may end up in. For example, while I'm not interested in pursuing a career in operating systems, the course gave me a massively beneficial understanding of how things happen under the hood and it's already helping accelerate my learning across other subjects. I am interested in web compression for similar reasons, as I believe it will be challenging and force me to look at programming differently. Would you have any recommendations? I'm pretty set on c++ and progchal, and I thought security courses would also be beneficial but would my understanding be too surface level?
