The author emphasizes the importance of having a bias for action and making it a habit to move forward, even with small steps, to avoid stagnation. They suggest that when seeking approval for an initiative at work, it’s more effective to ask for a chance to say no instead of asking for a yes, especially in small companies. For example, instead of asking a busy boss for permission to implement a new GitHub action to improve software quality—which could require considerable effort on their part—the author recommends

The author advocates for the use of text labels alongside icons in user interfaces, arguing that relying solely on icons can hinder usability. Many icons do not convey a clear, singular meaning, leading to ambiguity and requiring extra cognitive effort from users to interpret their meanings. For example, while a trash can icon typically represents "delete," a pencil icon may be interpreted as "create," "edit," or "draw," depending on context. This ambiguity slows down user navigation and interaction with the interface. Furthermore, as

The content introduces the FFmpeg School of Assembly Language, highlighting its goal to provide foundational knowledge in writing assembly language within FFmpeg. Assembly language directly translates to CPU instructions and is often referred to as "asm." The text emphasizes that much of FFmpeg's assembly code utilizes SIMD (Single Instruction Multiple Data), which allows for efficient processing of multiple data elements simultaneously—a method particularly effective for handling images, video, and audio due to their sequential data structure. Key terminology like “assembly function” and “vector
