    Article: 12 min

    Exploration of GitHub's dual ID system for object identification

    This article could help developers optimize their use of GitHub's API and improve the efficiency of their code, potentially leading to better integration with GitHub services.
    • GitHub uses two separate ID systems: node IDs and database IDs.
    • Node IDs are base64 encoded strings, while database IDs are integers.
    • The author discovered a method to extract the database ID from the node ID using bitwise operations.
    • Legacy repositories use an older format for their IDs, whereas newer ones follow a new format based on MessagePack serialization.

    Discussion (47): 13 min

    The discussion revolves around issues faced by API consumers due to GitHub's migration to a new ID format and the implications of using opaque IDs in API design. The thread highlights concerns about communication, unintended usage, and the potential risks associated with relying on undocumented behaviors.

    • GitHub's migration to new ID format was not properly communicated
    • API designers should be aware of unintended usage by consumers
    Counterarguments:
    • Counterpoint on the benefits of using opaque IDs, such as performance and obfuscation

  5. A 40-line fix eliminated a 400x performance gap from questdb.com
    224 by bluestreak 8h ago | | |

    Article: 36 min

    A commit in the OpenJDK project significantly improved the performance of `getCurrentThreadUserTime()` by replacing file I/O and complex parsing with a single call to `clock_gettime()`. This resulted in an average latency reduction from 11 microseconds to 279 nanoseconds, marking a 40x improvement.

    This performance optimization could lead to more efficient Java applications, potentially reducing resource usage and improving user experience.
    • 40-line deletion in os_linux.cpp resulted in a 40x performance improvement
    • Elimination of file I/O, complex parsing, and buffer management
    • Single syscall to `clock_gettime()` for user time extraction
    • Performance gap quantified as 30x-400x slower than `getCurrentThreadCpuTime()"
    Quality:
    Detailed technical analysis and benchmarking results

    Discussion (45): 7 min

    The comment thread discusses various aspects of measuring CPU time for JVM threads, including the cost and accuracy of measurements, the role of clock stability, and alternative methods like software perf events. It also touches on performance optimization techniques, such as using flamegraphs to identify inefficiencies in code.

    • JVM's thread activity reporting is expensive
    • Clock stability and accuracy are crucial for measuring CPU times accurately
    Counterarguments:
    • Measuring nanoseconds out of a millisecond or microsecond does not require an extremely good idea of the stability and accuracy of the clock.
