Time Travel Tuesday #timetravel a look back at the Adafruit, maker, science, technology and engineering world
1978 – The first unsolicited bulk commercial email (which would later become known as “spam“) is sent by a Digital Equipment Corporation marketing representative to every ARPANET address on the west coast of the United States.
Earliest documented spam (although the term had not yet been coined) was a message advertising the availability of a new model of Digital Equipment Corporation computers sent by Gary Thuerk to 393 recipients on ARPANET in 1978. Rather than send a separate message to each person, which was the standard practice at the time, he had an assistant, Carl Gartley, write a single mass email. Reaction from the net community was fiercely negative, but the spam did generate some sales.
2000 – The sport of geocaching begins, with the first cache placed and the coordinates from a GPS posted on Usenet.
Geocaching was originally similar to the 160-year-old game letterboxing, which uses clues and references to landmarks embedded in stories. Geocaching was conceived shortly after the removal of Selective Availability from the Global Positioning System on May 2, 2000, because the improved accuracy of the system allowed for a small container to be specifically placed and located. The first documented placement of a GPS-located cache took place on May 3, 2000, by Dave Ulmer of Beavercreek, Oregon. The location was posted on the Usenet newsgroup sci.geo.satellite-nav as 45°17.460′N 122°24.800′W. By May 6, 2000, it had been found twice and logged once (by Mike Teague of Vancouver, Washington). According to Dave Ulmer’s message, this cache was a black plastic bucket that was partially buried and contained software, videos, books, food, money, and a slingshot. A geocache and plaque called the Original Stash Tribute Plaque now sit at the site.
The activity was originally referred to as GPS stash hunt or gpsstashing. This was changed shortly after the original hide when it was suggested in the gpsstash eGroup that “stash” could have negative connotations and the term geocaching was adopted.
Over time, a variety of different hide-and-seek-type activities have been created or abandoned, so that “geocaching” now may refer to hiding and seeking containers, or locations or information without containers.
Each month we try and take a photo of what’s on the cover of magazines in our “We are what we celebrate” series of posts. Most of the time, it’s not so good other times it’s a little better. This month… progress!
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
