The first commercial spam was sent out on April 12, 1994 by lawyer Laurence Canter, who was trying to drum up business for his Arizona law firm.
J. Presper Eckert, inventor of the ENIAC, the Electronic Numerical Integrator And Computer, otherwise known as the first all-purpose fully electronic computer, dubbed the “Giant Brain” by newspapers at the time of its unveiling. Several of its vacuum tubes failed every day, rendering it inoperable half of the time. Nonetheless, it was in use by the U.S. military for nearly a decade, until its retirement in 1955.
On April 12, 1633, Galileo’ssecond trial for his heliocentric beliefs began. Galileo was found guilt of heresy and spent the remainder of his life under house arrest.

We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter
