    A fork of Instagram's experimental performance oriented greenfield implementation of Python. It features small objects; a moving GC; hidden classes; bytecode inline caching; type-specialized bytecode; an experimental template JIT. (by tekknolagi)

    This is also the pointer tagging scheme from the Ghuloum paper. I did not design it. Another tagging scheme I did not design is the Skybison scheme, which uses 0bXXX...XX0 to tag integers and 0bXXX...001 to tag heap pointers. This makes heap reads very easy (bias by -1 in addressing mode).

  • 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.
