#479 – Dave Plummer: Programming, Autism, and Old-School Microsoft Stories

Dave Plummer, a former Microsoft software engineer, is recognized for his work on Windows 95, NT, and XP, and for creating tools like Windows Task Manager. He shares insights from his journey with autism in his book "Secrets of the Autistic Millionaire." Plummer's early experiences with computers began with a TRS-80 Model 1, where he faced challenges in setup and programming. He fondly recalls the Commodore 64, which he preferred over the Apple II, and his programming journey included writing a Galaga clone in machine language.

Plummer's path to becoming a programmer was unconventional; he dropped out of high school but later returned to education after a life-altering experience. His interest in programming blossomed during a summer job at a phone company, leading him to Microsoft through cold emailing. He created Hypercache for the Amiga, which funded his education and caught Microsoft's attention.

He discusses the significance of MS-DOS in establishing Microsoft as a standard in the industry, explaining its limitations and his contributions to optimizing memory usage. Plummer reflects on the evolution of Windows, particularly the introduction of Windows 95, which marked a significant shift with its user interface and 32-bit support. He emphasizes the importance of effective tools and collaboration in software development, sharing anecdotes about the competitive environment at Microsoft.

The conversation touches on the psychological challenges of debugging, where Plummer spent a majority of his time fixing issues rather than creating new features. He humorously notes that his phone number remains in the source code for debugging purposes. The Windows Task Manager, which he initially developed as a personal project, was designed to be compact and efficient, with a focus on CPU usage tracking.

Plummer also discusses his involvement in porting Space Cadet Pinball to Windows, emphasizing the challenges of preserving the original game's physics. He reflects on classic games like Tetris and Solitaire, which were used as educational tools. His experience with Windows activation during XP development highlights the collaboration required to meet deadlines.

The conversation shifts to the evolution of Windows design, with Plummer expressing dissatisfaction with Windows 11's limited customization options. He critiques the user interface for its complexity and manipulative prompts, advocating for a more straightforward approach to user engagement.

Plummer shares insights on autism, discussing monotropism and the challenges faced by autistic individuals in social situations. He emphasizes the importance of clear communication and understanding individual motivations within teams. The concept of "masking" is explored, along with the emotional toll it can take.

He reflects on the significance of craftsmanship and the impact of subtle human interactions, particularly for those on the autism spectrum. The discussion includes romantic relationships and the importance of explicit communication in navigating social dynamics.

Plummer highlights the traits of autism that can contribute to success in programming, sharing details about his current projects, including reinforcement learning for the game Tempest. He discusses the future of programming, speculating on the role of AI in code generation and the potential evolution of programming practices.

The conversation concludes with a reflection on the meaning of life through creativity and the impact of technology on society, leaving listeners with a sense of appreciation for the complexities of programming and the human experience.
