About Code80vity Study Notes

Who writes Code80vity Study Notes and what it covers.

Code80vity Study Notes is a small set of study notes for people teaching themselves to program: the core concepts, a debugging routine, study habits, version control, and how to read the documentation you will depend on.

Who writes it

The notes are written by Ilya Kessler, a pen name for a self-taught developer who keeps notes while learning and tidies the useful ones for others. No teaching qualification or employer is claimed, and nothing here is a course.

About this address

This domain was previously used by a coding course platform. This site is independent and has no connection with that platform, its instructors, its students or its materials. No courses, certificates or accounts from the earlier site are available here, and nothing is sold.

How the notes are checked

Definitions are linked to their Wikipedia articles so you can read the source. The notes avoid statistics about salaries, job placement or study hours, because those figures vary widely and are easy to misuse.
