Where is JAVA pdf database?

Question

I remember that there was a site like "https://dzo.so" or something like that. There were bunch of tech-pdf stuff like Java, Python, Reverse Engineering etc. I can't find the site anywhere! Can you guys please help me and send some useful sites like I mentioned? Thank you.
