Little knew Leonard Kleinrock that the first network connection at his UCLA lab was going to bring us this mayhem of tweets and tits we call the internet. It was all about the possibility of total thermonuclear holocaust, back then.
The image above shows the log entry of the first meaningful connection between two computer nodes. It happened on October 29, 1969. However, the very first heart beat, the first actual connection in which bits were exchanged between two hosts happened 40 years ago today.
Later those two nodes evolved into this:
That's the first logical map of ARPANET, the world's first operational packet switching network created by the Advanced Research Projects Agency. It's objective was to provide data connectivity at all times for the U.S. government, who wanted a way to keep communications in the case Ivan emptied its ICBM silos all over the United States and its allies. Years later, ARPANET became the Internet.
So may God bless the military, for without them we wouldn't be writing, and reading Gizmodo every day. Happy birthday, ARPANET! Or internet! Or arpaternet! Or whatever the hell you call yourself these days, you old promiscuous data whore you. [Wikipedia and LA Times via Boing Boing]
