Code! Beautiful code! How I've missed thee! As mentioned before I'm hip deep in the middle of an arm rewrite. Not only to overhaul the arm codebase, but to ensure Stem will be up to snuff for a Tor GUI or web dashboard (projects I'd *love* to jump into someday). I'm delighted to announce a nice bi

-BEGIN PGP SIGNED MESSAGE- Hash: SHA256 Hi all, While working on peer-to-peer hidden services I've been wondering how long two clients need to wait before arriving at the same view of the Tor network. The answer, which I find surprising, is that this is never guaranteed to happen. Here's

Thanks isis. We worked on PIR-Tor a while ago, so my recollection could be a bit rusty, but here are some thoughts. 1) From a performance perspective, the best results are obtained by using the information-theoretic variant of PIR-Tor (ITPIR) (as opposed to the computational variant). As you corre
