Shutdown Your Computer for 1 Minute in Honor of ENIAC
Statement from Jim Scherrer, CEO Compuseum
Shutdown Your Computer for 1 Minute in Honor of ENIAC
I'm requesting that all citizens of the world turn off their computers for one minute at two fifteen o'clock (2:15PM) Eastern Standard Time on February 15th (2/15) as a tribute to the ENIAC, the world's first all electronic, programmable computer. ENIAC Day celebrates this great computer's memory and its essential role in the march of the computer age. Similar interruption of web servers, data centers and critical host computers is deemed too dangerous since so many essential services rely on this computer power. A one minute shutdown of all non-essential computing devices is a fitting demonstration of the debt owed to the ENIAC and the unique efforts of its founding creators Presper Eckert and John Mauchly and founding programmers Betty Jean Jennings (later Bartik), Kay McNulty (later Mauchly Antonelli), Frances Bilas (later Spence), Marlyn Wescoff (later Meltzer), Betty Snyder (later Holberton) and Ruth Lichterman (later Teitelbaum) (see www.ENIACDay.org for details).
Power down your computer for one minute in honor of ENIAC on February 15th at 2:15PM

All there is to know about the history of computing!
A highly recommended book about how the computer became universal.
Over the past fifty years, the computer has been transformed from a hulking scientific supertool and data processing workhorse, remote from the experiences of ordinary people, to a diverse family of devices that billions rely on to play games, shop, stream music and movies, communicate, and count their steps. In A New History of Modern Computing, Thomas Haigh and Paul Ceruzzi trace these changes. A comprehensive reimagining of Ceruzzi's A History of Modern Computing, this new volume uses each chapter to recount one such transformation, describing how a particular community of users and producers remade the computer into something new.
Authors Haigh and Ceruzzi ground their accounts of these computing revolutions in the longer and deeper history of computing technology. They begin with the story of the 1945 ENIAC computer, which introduced the vocabulary of "programs" and "programming," and proceed through email, pocket calculators, personal computers, the World Wide Web, videogames, smart phones, and our current world of computers everywhere--in phones, cars, appliances, watches, and more. Finally, they consider the Tesla Model S as an object that simultaneously embodies many strands of computing.
