A long-running analytic task on big data often leaves a developer in the dark without providing valuable feedback about the status of the execution. In addition, a failed job that needs to restart from scratch can waste earlier computing resources. An effective method to address these issues is to allow the developer to debug the task

An ammonite trapped in Burmese amber
Proceedings of the National Academy of Sciences of the United States of America, 2019 Significance Aquatic organisms are rarely found in amber, but when they occur they provide invaluable evidence for the better understanding of amber taphonomy and past ecosystems.

Abstract This chapter covers the complexity of the human relationship with amber. Regardless of the notions of being a gemstone or fossil, amber is best understood as a transformed organic material of great age, which is largely similar to coal.

The Paleontological Society Papers, 2014
The amber fossil record provides a distinctive, 320-million-year-old taphonomic mode documenting gymnosperm, and later, angiosperm, resin-producing taxa. Resins and their subfossil (copal) and fossilized (amber) equivalents are categorized into five classes of terpenoid, phenols, and other compounds, attributed to extant family-level taxa.
