In celebration of Unix’s 50th anniversary, the CHM Software History Center is delighted to make publicly accessible for the first time some of the earliest source code produced in the Unix story.
Robert W. “Bob” Bemer - who worked at Lockheed's Missile Systems Division in Van Nuys and who would become its IBM 650's power user - carefully cut out the article and placed it into a scrapbook. In 2018, through its Access to Historical Records grant from the National Archives' National Publications and Records Commis
In the realm of software, a “branch” is a computer instruction that causes a shift from the default pattern of activity to a different sequence of actions, a different way of moving ahead if you will. For Ann Hardy, a pioneer in timesharing software and business, her contributions to computing were achieved through rep
The photograph was dated 1950, a date when a now unimaginably small number of humans had ever beheld a computer, no less touched one, and when unabashed racism and discrimination was endemic on the American scene. Who was the young African-American man who nevertheless sat at the controls of this storied machine? What
CHM's Software History Center has been conducting “video ethnographies” to record and preserve the experience of running historical software. Over the course of 2018, the center has conducted two video ethnographies surrounding a key moment at the end of the late 1980s and early 1990s, the birth of multimedia. Watch an
Perhaps you are like me: You’ve aware that quantum computing is a hot topic today but have a nagging feeling that you don’t really have a good picture of what it’s all about. Sure, you know it has something to do with the unintuitive behavior of the world described by quantum mechanics—cats in boxes that are blends of
For the invention of the first commercial erasable programmable read-only memory (EPROM), which enabled rapid development of microprocessor-based
For the creation and evolution of the Python programming language and for leadership of its community.
QuickTime, the pioneering mass-market digital video format for personal computers, was developed by Apple and released in 1991 on the Macintosh. As part of the MPEG-4 video standard, QuickTime technology can be found in every device today that plays digital video, from cell phones to 4K streaming TVs.
In 1950, the physicist Arnold Nordsieck built himself this analog computer. Nordsieck, then at the University of Illinois, had earned his PhD at the University of California, Berkeley, under Robert Oppenheimer. To make his analog computer for calculating differential equations, the inventive and budget-conscious Nordsi
