Week 56 — Case studies IV

System design and distributed systems fundamentals · Read / diagram

Medium

Phase 5 — System design and distributed systems fundamentals

Overview

Uber, web crawler

Mode this week: read_diagram. Match the work to that mode (operating model): implement ships running code; read/diagram ships a doc; deploy/benchmark ships a measured run. Personal dates, checkboxes, and the RPG layer stay in a learner journal.

Core deliverable

Two design docs

Optional depth

Add a benchmark, failure-mode analysis, and a short production trade-off note.

Week loop (from the cookiecutter journal)

Mon — Theory: Uber, web crawler
Tue — Build: start the core deliverable above
Wed — Systems / papers: one paper or system note (see below if this week has assigned reading)
Thu — Eval / interview: write the four evidence items
Fri — Algorithmic Forge: Resource-allocation design; Week 57 graph boss fight (45-120 min; Core / Supporting)

Forge theme: MST, Euler paths, max flow, min-cost flow, matching

Leetcode Darbar (parallel)

This week's band (46-57): Graphs, trees, greedy, DSU, range queries. Production connection: System design, workflows, sharding, scheduling.

Standard: one aligned problem. Auror: the five-slot queue on the Darbar page. Tracker stays in the learner journal.

Topics: graphs · greedy · range query · trees

All Paths From Source To Target · medium · graphs
Longest Palindrome · easy · greedy
Queue Reconstruction By Height · medium · range query

Evidence contract

Every core week records all four (cookiecutter journal/weeks/week_056.md):

Code / implementation (or the design artifact on a writing week)
Benchmark / result
Design doc / technical explanation
Retrospective / learning note (Sailboat: destination, wind, anchor, rocks, heading)
