About whilo

Christian Weilbach is a researcher and systems builder working on structured learning, persistent memory, and runtimes for intelligent systems. He completed a PhD at UBC on structured amortized variational inference, after earlier work on Bayesian GANs, dictionary learning, and online learning for spiking neurons running Boltzmann machines. He’s currently building the Datahike ecosystem, an immutable, versioned data substrate for intelligent systems, including tools for vector search, branching SQL, and git-like search infrastructure. He has given talks at DeepMind, OpenAI, and MILA, and is interested in systems for deliberate, programmable organization of work, knowledge, and learning.

    Hey. Hybrid in which sense? I have integrated Stratum's columnar indices as a secondary index in the new query engine of https://github.com/replikativ/datahike itself, so for numer…

    Hi HN - I’m the author of Stratum. The headline benchmark result is that on 10M rows, Stratum is faster than DuckDB on 35 of 46 single-threaded analytical queries, despite running …

    Hi HN - I’m the author of Stratum. Stratum is a columnar SQL engine built on the JVM exploring two ideas: • SIMD execution using the Java Vector API • copy-on-write branching for t…

    No, he lives in Switzerland now (Lugano as far as I know). Switzerland is a big magnet for European talent, as is Germany to a lesser degree. My point though was that Germany was n…

    As a German coming from Mannheim, and now living on the Canadian West coast, I have to say that this is exactly the mindset that makes it so difficult to innovate in Germany. While…

    I see, so your problem was that you wanted to scan over all Datoms for one entity over a time period and you would have needed to have an EVAT index? In Datahike it would be fairly…

    Interesting, honestly speaking we have not thought about time series data a lot yet, but I think we should be able to provide custom indices and extend Datalog with more efficient …

    Hey, one of the core architects of Datahike here. As a Clojure company we are also super happy that Nubank made Clojure and Datomic much more credible with this move. While Datomic…
