Dave is a Canadian-American programmer and entrepreneur. He created the Task Manager for Windows, the Space Cadet Pinball ports to Windows NT, Zip file support for Windows, HyperCache for the Amiga and many other software products.
After landing an intensive interview with Microsoft, Plummer moved to Redmond, Washington and began working for the tech company in 1993. He began his career with Microsoft as an intern, but was later offered a full-time job with the company for $35,000 a year.
While employed at Microsoft, Plummer began creating the Task Manager program at his home. Plummer eventually showed his newly developed program to Dave Cutler, who allowed him to bring his project into work, upload it to the system, and fine tune the program into what was eventually released with the 1996 shipments of Microsoft computers. During his tenure with Microsoft, Plummer worked on software such as MS-DOS 6.2 and Windows NT, including features of note like Task Manager and Space Cadet Pinball.
Plummer left Microsoft in 2003 and continues to code in his free time. He has since started his own YouTube channel (Dave's Garage) where he creates a variety of content regarding computer programming and, his personal interest, cars.
After nearly 25 years of anonymity, on May 25, 2020, Plummer came forward on a Reddit post and admitted to developing the Task Manager application. In his post, he shares some tips and tricks for using Task Manager.
Exactly six months later, on Nov 25, 2020, Plummer came forward again with a YouTube video that described his role in selecting the ballast data for the Windows XP anti-piracy protection. Plummer claims to have used the digital images of Microsoft Bob as the initial seed into the pseudorandom number generation that produced the ballast, so that (in his words) the "Digital spirit of Bob" was included with the approximately 500,000,000 Windows XP installations.
He has been issued six patents in the software engineering space.David Plummer was the engineer responsible for designing and programming the Windows Task Manager back in 1994, and this plenary revisits the origins of the application, its design, and unique aspects of its implementation.
