Hmm, a PDF hosted on a random personal web site at a University in Brazil. Seems legit.

Can we please not post links to stolen (presumably-)copyrighted materials here?

If you'd like to compensate the author, consider buying the collection it's published in:

I highly recommend Ted Chiang. I really enjoyed "Story of your Life" available in this short story collection of the same name:

Some of the stuff is a but uneven but he's written some of the most thought-provoking sci-fi I've read in some time.

That story is in Stories of Your Life and Others; I'd recommend the whole collection:

Someone who never appears on these list but is one of the rising stars in Scif-Fi isis Ted Chiang. He's not written a full length novel yet but his short stories and novellas are mind blowing, best stuff I're read since early Egan. Check out:

Stories of Your Life and Others

The Lifecycle of Software Objects*

*if there's a more HN title for a novella ever I haven't heard of it!
