    Operational Transformation and Conflict-Free Replicated Datatypes are very different from each other. As the author explains, OT relies on some ordering of system events, and CRDTs…

    Stegasuras is convincing work and the quality looks excellent. I wrote a steganographic tool in this same spirit back in 2011, called Plainsight. Back then, we didn't have deep lea…

    The TimescaleDB benchmark code is a fork of code I wrote, as an independent consultant, for InfluxData in 2016 and 2017. The purpose of my project was to rigorously compare InfluxD…

    Good idea, the READMEs would be best of all.

    As I said, your approach is a clever way to use the GitHub API. I think you need to change the title and readme to indicate that this isn't an LDA index of GitHub descriptions. To …

    This only uses LDA on your starred repository descriptions, to find topic terms that describe your starred repositories. These topic terms are then used to query the GitHub search …

    Why has this article been removed from the top 250 news results? It was #1 for a few minutes, then #5, and now it's gone. We've successfully discussed much more risqué topics here …

    A) How would you characterize the differences and similarities between AlphaGo and the best human players? B) How has human play style changed since AlphaGo's introduction? C) What…

    TensorFlow is a dataflow computation system. Keras is for building neural networks. Each exists at a different level of abstraction.

    How does this contrast with Answer Set Programming (using e.g. clasp)?

    You could have answered all of your questions with "finitely many", because, after all, we can each only perform a finite number of actions in the world. In general, the infinite h…

    Interesting. Whether that approach is efficient depends entirely on the workload. That complicates the analysis. (And one of the major benefits of skiplists is that the analysis is…

    I've read this page before, and again today, and I still don't understand how these unrolled lists are supposed to work in practice. Based on the author's example at https://i.imgu…

    This is pulling from a too-small data set. I was able to get correct detections with too little data: In no world is a circle with a bar coming out of it a "dumbbell".

    The world is bigger than web companies. For contrast, one experiment at CERN produces 40TB/sec of sensor data, before downsampling and filtering: https://en.wikipedia.org/wiki/Comp…
