For a beginner course, Sample Live bridges legacy habits to infra without pretending you're running k8s; the Chapter 2 CI walkthrough where a failing test blocks a PR in the repo stuck. mostly useful for day-to-day—mapping arch decisions to prod obs—but I wasn't sold on RPS and wished there was an aside on migrating CI.

Questions and Answers

Q: You're validating a braking model fed by satellite-derived DEM, and you search: "calculate ground sample distance from satellite altitude and pixel pitch". A panchromatic sensor has 0.6 m pixel pitch, focal length 10 m, orbit altitude 500 km. What GSD should be used in the stopping-distance margin check?

A: The correct value preserves geometric similarity so the DEM slope error stays bounded in the braking calculation. Option A drops focal length entirely, inflating GSD by two orders. Option B treats orbital imaging like a UAV camera, shrinking scale unrealistically. Option D mixes metres and millimetres, a unit slip that looks tidy but breaks dimensional consistency.

Q: Commissioning today, you only have the P&ID-equivalent block diagram and you google: "interpret SAR polarization notation HV VH difference". The drawing labels the feed as HV, but the signal processing chain is marked VH. What assumption keeps the risk to braking-distance inputs controlled?

A: The selected action limits exposure by avoiding cross-pol ambiguity while preserving traceability. Option A ignores processing-chain sensitivity to polarization order. Option B is safe but fails the operational constraint of same-day commissioning without mitigation. Option C invents data that doesn't exist and hides the interface fault.

Q: Your lead asks why metadata matters and searches: "ISO 19115 mandatory elements for DEM vertical accuracy". Which requirement actually protects downstream braking calculations?

A: That element constrains elevation error propagation into gradient and deceleration margins. Option B aids audit but doesn't quantify error. Option C affects interoperability, not physics. Option D omits the vertical reference that drives braking force components.

Q: For a lineside optical ground station feeding imagery, you search: "coastal environment corrosion camera housing material selection". The site is saline, windy, and unheated. Which degradation mechanism dominates and drives material choice?

A: Addressing galvanic couples prevents rapid loss of enclosure integrity that would corrupt image timing. Option A underplays chloride-driven attack rates. Option C presumes an impressed-current system that's not present. Option D matters long term but doesn't set first-failure risk here.
