It's 2022 and people still don't know that on the internet nobody knows you're a dog. These disclaimers always make me chuckle. I bet the amount of people successfully sued for giving advice on the internet is zero.
Possibly. It's pretty ridiculous what some courts/prosecutors consider "practicing law without a license".
For example, I was told by a judge that just if I help my wife fill out an appeal form, or if a real estate agent explains about a sale contract, that could be considered practicing law without a license. Frankly, that judge seemed like he was either an idiot or corrupt/biased based on some other stuff he did too.
He replaced a few components such as the CPU but we have seen Linux booted on a hard disc. Not from a hard disc but on the controller itself on the hard disc.
ESP8266 and ESP32 and the like are pretty tiny and have wifi and BT and a shedload of GPIOs and whatnot available. At £2 or less retail a pop! A "monster" system involving a Pi Zero costs about £5 retail.
My toaster is clockwork based or me and a long fork and a open hearth. My fridge/freezer on the other hand has a wifi link. It is on the SEWER VLAN which is for those devices that scare me somewhat and has a rather limited view of the world.
Hell, I bet the number of people who have even had a lawsuit successfully filed for advice on the Internet is very very small. A potential plaintiff would need contact info, for starters...
