I actually used print from phone for the first time in years today. Raspberry pi print and scan server was a great time and money saver project. Runs on a zero.
I can remember when those were thousands of dollars even before wifi.
@thendrix I hated the Raspberry Pi for lying its way into the FOSS world so I paid twice the price for some mysterious board from China. I've only mined as a benchmark and after putting new paste on a CPU. I donated the hashes to the developers.
I never ran mining boxes, but knew someone that had a building dedicated to it in the early days.
