  • Clock Syncronization Protocol (Other amazing things)

    The main deliverable of my master's dissertation is a clock synchronization protocol (CSP) for general-purpose transactions at scale. In designing CSP, we employed a hybrid logical clock, HLC, that leverages the best of logical clocks and physical clocks. HLC is helpful for tracking causality relationships of the overlapping events. To maintain clock offsets among sets of nodes, we utilized Marzullo intersection algorithm. Synchronization of clocks in a network requires comparing them directly or indirectly with respect to differences in time and (possibly) frequency. The approach adopted here is based on variant of Christian's algorithm (Probabilistic clock synchronization).

  • Orchestrating a Background Job Workflow in Celery for Python (Publication)
    In this article, I will try to give you a good understanding of which scenarios could be covered by Celery. Not only will you see interesting examples, but will also learn how to apply Celery with real world tasks such as background mailing, report generation, logging and error reporting. I will share my own way of testing tasks beyond emulation and explain a few tricks that go beyond the official documentation and took me hours of research to discover myself.
