    The whole point of using a proper CRDT is that it's easy to reason about what it does. It took me a while to figure out the details of how to build one.

    The endgame of effectiveness of stego with this framework of published techniques versus customized detectors for those techniques specifically is going to be much, much more diffi…

    To clarify: There is not, and cannot be, a universal DissidentX encoding detector. It will always, always, be possible to iterate arbitrarily on the encoding technique, and this it…

    This tool allows for the specifics of how the encoding is done to be changed without the decoding algorithm needing to be changed ever, so yes in fact it is ready to be used, altho…

    There was a CIA contractor who outright defrauded them claiming that he had tools which were detecting steganographic messages used by terrorists on the internet. He didn't get pro…

    This is a framework for steganographic schemes, not a specific steganographic scheme. The specific ones thrown in are just for demonstration purposes. The versatility of this appro…

    In San Francisco at BitTorrent Inc. we're hiring a number of developer positions, most heavily web front end engineers. https://angel.co/bittorrent

    Low enforcement might start issuing warrants to hand over your customer list as a list of potential suspects. If I were you I'd start that rumor myself.

    The traditional overlay approach involves a bunch of full trees, and uses multiple trees as a way around dealing with leaf nodes being unutilized. My approach uses multiple groupin…

    Those other technologies have latencies measured in dozens of seconds or minutes, while mine is measured in seconds.

    Over time I've made interview challenge problems progressively easier, as I've found that the trickier ones don't give any more information than the easier ones. My challenge now b…

    You should probably make your code robust to this sort of data corruption in the future.

    Looking at the correlation in students between year to year makes clear what's going on - http://garyrubinstein.teachforus.org/2012/03/06/analyzing-re... There's such a high correl…

    In regards to the question of 'Is it legal to fire this person for this?' at least in California it's a slam dunk - the answer is yes. One of the questions on the harassment traini…

    From my sketchy understanding of your description of the algorithm, it seems like a 2d version of the patterns in gaps you see when you look at cornrows.

    That's what you would do IF you were going to be serious about making the router drop packets in a way which actually helps. I don't expect it to happen any time soon.

    There's some detailed writeups of the algorithms in the LEDBAT documentation. As for commentary, that's distinctly lacking, and my post is filling in some of the gap.

    BitTorrent is using uTP just fine, which is only, you know, most of the upload from consumer internet connections, and we're working on getting the same things crammed into TCP wit…

    uTP carries the bulk of all BitTorrent transfers at this point. This would seem to imply a certain level of success.

    They can have their throughput without running a denial of service on their net connection. If you assume that they'll DOS themselves for the fun of it anyway, then I can't help yo…

    uTP isn't based on CurveCP, and CurveCP is nowhere near as mature as uTP is.
