   The article makes for an interesting technical read, and points to some very important issues, such as debugging in a multicore environment. Even so, I encourage anyone reading this article to keep in mind that there is a massive amount of

   I had the good fortune to be in Dybvig’s compilers class in the mid 2000s. The way it was presented really brought the concepts to life and made it enjoyable.

    A few years ago, our research group published a data structure, called Chunked Sequence, that is similar to the Finger Tree. In short, Chunked Sequence features the same asymptotic profile as does Finger Tree (neglecting persistence) and, i
