The basics of doing PID design

This is a glorified scrapbook. A collection of entirely random information, images, books, files and etc.., that a few friends and I have for whatever reason found interesting througout the years. It was originally on an instllation of Media Wiki, and I recently manged to move it here.

Also I prefer not to spam everyone's social media feed with all this, but for the few who apparently would like to be kept in the loop, here you go.... This one's public and has a feed. [Happy?]

[This is -not- in any way, shape or form replacing my blog. That one's still here. ]
