Well, the paper my advisers and self have been laboring over was submitted and accepted to the ACM SIGPLAN Workshop on Memory Systems Performance and Correctness (which is in Seattle this year). More so, I wrote the original draft (with some incomplete pieces). It ended-up being rewritten by my advisers (and a ton of things were added!). Needless to say, it represents hours and hours of work, and composes ideas from their genius. It was great to work on this paper with them, and I am humbled that it was accepted. I have been implementing code for ages now to represent these ideas, basically a combination of region-based memory management and garbage collection.
On another front, I have been working on more PDF hackery. I wanted to make a PDF-grepping utility. I have a basic implementation cooked-up but the key piece is the simplistic PDF text-extraction library that I wrote (note that it is not fully featured and does not account for all encodings and compression schemes). I present upon the world libnachopdf because it ain't yo' PDF. Well, maybe it is your PDF, but that doesn't matter. Get 'yo nacho on over here.
