  • yugabyte-db

    YugabyteDB - the cloud native distributed SQL database for mission-critical applications.

    Project mention: Best Practice: use the same datatypes for comparisons, like joins and foreign keys | dev.to | 2024-02-01

    It is possible to apply Batched Nested Loop but with additional code that checks the range of the outer bigint and compare it only if it matches the range of integer. This has been added in YugabyteDB 2.21 with #20715 YSQL: Allow BNL on joins over different integer types to help migrations from PostgreSQL with such datatype inconsistencies.

  • librdkafka

    The Apache Kafka C/C++ library

    Project mention: Do you use Rust in your professional career? | /r/rust | 2023-05-09

    recent PR: https://github.com/confluentinc/librdkafka/pull/4275

  • InfluxDB

    Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.

  • haproxy

    HAProxy Load Balancer's development branch (mirror of git.haproxy.org)

    Project mention: HAProxy is not affected by the HTTP/2 Rapid Reset Attack (CVE-2023-44487) | news.ycombinator.com | 2023-10-11

    I wanted to try it out just now but hit a roadblock immediately - it cannot automatically obtain and maintain TLS certificates. You have to use an external client (e.g. acme.sh), set up a cron to check/renew them, and poke HAProxy to reload them if necessary. I'm way past doing this in 2023.



  • Kore

    Project mention: Splitting the stack - is there a library for this? | /r/C_Programming | 2023-05-17
  • varnish-cache

    Varnish Cache source code repository

  • blis

    BLAS-like Library Instantiation Software Framework

    Project mention: BLIS: Portable basis for high-performance BLAS-like linear algebra libs | news.ycombinator.com | 2024-01-24


    It seems that the selling point is that BLIS does multi-core quite well. I am especially impressed that it does as well as the highly optimized Intel's MKL on Intel's CPUs.

    I do not see the selling point of BLIS-specific APIs, though. The whole point of having an open BLAS API standard is that numerical libraries should be drop-in replaceable, so when a new library (such as BLIS here) comes along, one could just re-link the library and reap the performance gain immediately.

    What is interesting is that numerical algebra work, by nature, is mostly embarrassingly parallel, so it should not be too difficult to write multi-core implementations. And yet, BLIS here performs so much better than some other industry-leading implementations on multi-core configurations. So the question is not why BLIS does so well; the question is why some other implementations do so poorly.
