2988 questions of the kind that actually get asked — in interviews, in architecture review boards, and by the person who has to run the thing at 3 AM. Every answer states the trade-off rather than the slogan, and says when the obvious choice is the wrong one.

    A 30-month database migration was funded entirely on the vendor's end-of-support date. Oracle was reported in February 2025 to have moved Premier Support for Database 19c out to the end of 2029 with Extended Support to the end of 2032. What happens to your programme over the next two quarters, and what do you change this week?

    A live-sport streaming service is planning for a cricket final. Marketing says "be ready for a big audience". The semi-final peaked at 1.8 million concurrent viewers and climbed from 400000 to 1.8 million in roughly 90 seconds at the first ball. Segments are 4 seconds long. Roughly what does the final demand, and which of those numbers actually constrains the design?

    A short-video recommendation service was designed when a median session pulled 20 videos and feature computation took 40 ms. Two years later sessions pull 200 videos, the model is larger, and p99 recommendation latency has quietly tripled - yet no single change looks responsible. How do you diagnose this as a constraints problem rather than a code problem?
