So you want to self-publish books and courses on programming
Any suggestions for fulfillment on PDF ebooks? My kickstarter for my LaTeX book¹ is almost over and I have enough backers that I think I want to do something a bit more sophisticated than just send people a download link (ideally, I'd like to have individually watermarked PDFs for each backer to act as a social deterrent to uploading the file to download sites). It'd be nice also if they could come back later to get a corrected version of the PDF if I do updates in the future.²1. https://www.kickstarter.com/projects/preppylion/the-preppy-l...2. I'm working on being meticulous about typos but I know they will happen, plus there will likely be updates to LaTeX that will require some minor changes in the text as time goes by.
