NT is often touted as a "very advanced" operating system. Why is that? What made NT better than Unix, if anything? And is that still the case?

Parallelism can exist without concurrency, but concurrency can enable parallelism as it provides a structure to solve a problem with parts that may be parallelized.

The biggest players’ scaling tricks are becoming increasingly relevant for the rest of us, which has led to the proliferation of architecture inversion.

While most USB-C docks are small enough to toss in your bag, the Aurora is anything but portable. This 47.3" wide monitor stand packs bays for four SATA

Cell-based architecture has emerged as a response to many challenges associated with distributed systems. It employs the bulkhead pattern to isolate failures to a fraction of the affected infrastructure footprint and prevent widespread impact. Cells can also help organize large architectures into domain-bound deployment and delivery units, which provides essential sociotechnical benefits.
