why are you posting pirated copies of copyrighted material to HN?

Thank you, packetslave!

So that people can read it, I would assume.

that's... not how copyright works

For those who don't read Farsi (I think it's Farsi, anyway), that link is somewhat less than useful...

You just have to press the blue icon if you want to read online (through .pdf nonetheless) or the orange one to download it. I don't read Farsi, but if you hover over those icons, you can see the link and the pdf is in English.

If you click the buttons at the top they take you through to english pdfs
