University Courses

Harvard CS50 2020: Intro to Computer Science

CS50 is Harvard University's introduction to the intellectual enterprises of computer science and the art of programming.

CS50 is an entry-level university course that teaches students how to think algorithmically and solve problems efficiently. It is suitable for advanced high school students or university students of all backgrounds.

Topics include abstraction, algorithms, data structures, encapsulation, resource management, security, software engineering, and web development.

Introduction to Computer Science and Programming in Python (MIT)

This course by MIT is intended for students with little or no programming experience. It aims to provide students with an understanding of the role computation can play in solving problems and to help students, regardless of their major, feel justifiably confident of their ability to write small programs that allow them to accomplish useful goals. The class uses the Python 3.5 programming language.

Computer System Engineering (MIT)

This course covers topics on the engineering of computer software and hardware systems: techniques for controlling complexity; strong modularity using client-server design, virtual memory, and threads; networks; atomicity and coordination of parallel activities; recovery and reliability; privacy, security, and encryption; and impact of computer systems on society. Case studies of working systems and readings from the current literature provide comparisons and contrasts. Two design projects are required, and students engage in extensive written communication exercises

Computer Science for Business Professionals (Harvard)

This course is a variant of Harvard College's introduction to computer science, designed especially for business professionals. It empowers students to make technological decisions even if not technologists themselves.

Topics include cloud computing, networking, privacy, scalability, security, and more, with an emphasis on web and mobile technologies.Students emerge from this course with firsthand appreciation of how it all works and all the more confident in the factors that should guide their decision-making.

This course is designed for managers, product managers, founders, and decision-makers more generally.
