As a non-major who is interested in the path of a developer, I happened to come across this lecture on algorithms, and it had all the information I wanted. This lecture provides a rough direction for problems that I will face in the future in addition to the problems I am currently facing, but it fills in the details with various reference materials and information. If you feel that this lecture is old, it is probably because you do not have the will to study on your own. It provides you with how to properly open your eyes to development, how to find your way, and the most basic and average information, but it also tells you that each person's details can be different within that. I recommended this lecture to people around me who are in a similar situation, and I do not regret it. I am writing a review after taking this lecture up to 23 times, and I dare say that this lecture is like a companion that you gradually take when you need it. If you find your way and information here, it would be good to put it down for a while and start studying. To sum it up in one sentence, it is a 'non-major developer dictionary - 90% of what you are looking for'.
