  • The Android Developer's Journey into Hardware Observability

    by Victor Lai

    In this article, I walk through how the growth of internal observability tooling for an AOSP device might look like, and the variety of pitfalls one might encounter as they scale from 1s to 10s to 1000s of Android devices in the field, based off my experience talking to AOSP developers and teams, and personally as an Android app developer working on AOSP hardware.

  • Why std::this_thread::sleep_for() is broken on ESP32

    by Steve Noonan

    A curious bug appearing after upgrading to IDF v5 led me into a deep dive of how std::this_thread::sleep_for() is implemented on the ESP32. I discuss how the IDF implements pthreads and newlib to provide C++ threading functionality. The results are surprising: a simple 10 millisecond sleep was killing performance, but only in the new version of IDF due to an interaction between libstdc++ and usleep().
