Packt Publishing is a UK-based technical publisher that has been releasing books, video courses, and subscription content for software developers since 2004. The Packt catalog is one of the broadest in the industry — covering essentially every active programming language, framework, and infrastructure tool — and operates as both a book publisher and a video-course platform.
The CourseFlix listing carries three Packt courses spanning topics typical of the broader Packt catalog: OpenCV 3 by Example, Learning Salt (DevOps configuration management), and Advanced HTML5 Game Development. Material is paid and aimed at developers picking up specific technologies through structured video walkthroughs.
