USB On-The-Go
USB, the Universal Serial Bus, was first released in 1996. It did not achieve widespread adoption until some years later; for most of the '90s RS-232-ish serial and its awkward sibling the parallel port were the norm for external peripheral.

It Matters Who Owns Your Copylefted Copyrights (2021)
Throughout the history of Free and Open Source software (FOSS), copyright assignment has simultaneously been controversial and accepted as the norm in our FOSS communities.

I am rich and have no idea what to do
