Gregory's Server@dabeaz Uh, there were a number, and I enjoyed these "clicking" moments; my highlights were discovering
* computers and BASIC early at the age of 7,
* how the HDD head parking tool at school worked from disassembly, and slightly adapting it for a teacher
* the idea of rule-driven programming languages, and computing a fixed-point of facts in Datalog, such as how a PNG file is composed from its parts according to data format rules,
@dabeaz * the world of functional programming, immutability, applying it to streams, and then reactive, turning pages of source code in (at least for me) eye-openingly simple & concise pivoting / wrangling of data,
* event-driven architectures, CQRS and how processing event streams is "just" folding, partitioning of events, and how this affects the extensibility and horizontal scalability of systems
* and lots more
