Maybe things have changed, but in the US it used to be a question of when does a digital file “exist”. The law was: when you buy a digital asset, the first time that asset is instantiated is the one true version of the file. To sell it you MUST sell the device where it first appeared. So you have to sell the computer, phone, or tablet that was used to download it. Maybe that law has been revised.
Pro and hobbyist. I started by learning Basic back in the late 1970’s. Got a EE with strong emphasis on Analog and DSP. Did analog for test and measurement systems but had to add microprocessors (and EPROMs and RAM) to build the systems that control the analog. For embedded I learned C. For PCs I did Basic, Forth (ugh), Turbo Pascal, Delphi, then C#. I’m heavy into unit testing. I did web development as well, back in 1997 to maybe 2010. Perl, PHP, MySQL, Linux, then Drupal. A lifetime ago.
I can’t tell what I’m working on now (professionally) but hobby-wise I do a lot of arduino stuff and some of it has been a blast. I did an automatic dog food dispenser a few years back that was an amazing tour of engineering your way out of failure. The look on my dogs face when the MK1 version sent a fire-hose stream of dog food across the room was awesome.
Look, we all know the only thing stainless steel is good for is the temporal flux dispersion. In all other ways it’s a PITA.
