A rapid roundup of concrete takeaways: research software engineering teams operate as small in‑house consultancies (<10 people) and pick Django for security, common tooling and speed; salsa maps to three states, nine transitions via finite state machines; PyCamp is 30 people for four days building ad hoc projects (they even finished a laser-tag prototype); a custom timeseries DB stores 58 billion points, 61 GB using Gorilla‑style deltas; a context manager patches Django Reversion to record data migrations; layered architecture enforced with import-linter; class‑based emails improve testing; iNaturalist hosts 62M observations used in 3,600 papers; spec‑driven docs/tests use Playwright and Jinja2; CPR basics: 120 bpm compressions and the recovery position.
