Show HN: Top PDFs Posted to Hacker News in 2018
The SRE book was available as PDF till August 25, 2018 https://news.ycombinator.com/item?id=17614907#17624523. I tried to find it but seems not be availble anywhere as PDF. I could only find Kindle (with limited anotation), at safaribooksonline (with even less anotation capabilities), at https://landing.google.com/sre/sre-book/toc/index.html or as print-on-demand.
