Our paper, "Mint: Java Multi-stage Programming Using Weak Separability" (pre-print PDF), has been accepted to PLDI 2010. We look forward to spreading the word about Mint in Toronto!
Mathias just gave the first presentation about Mint in the COMP 600 graduate seminar at Rice. The slides for "Mint: A Multi-stage Extension of Java" are available (PDF).
Finally, you may already have noticed that the blog has a new URL: www.javamint.org. We currently also have some problems with the implementation URL; for now, you can use http://mint.concutest.org as a resource hub for everything Mint-related.
