Build the mathematical maturity needed to read algorithm textbooks, understand asymptotic analysis, write proofs by induction, and reason about recurrence relations. This is not a math course — it is the minimum mathematical toolkit for everything that follows.
There's a strange gap that nobody talks about honestly. You can build production Rails applications that serve millions of requests. You can design database schemas, debug race co…

Work through each item before the checkpoint.
Write a Ruby script that implements 5 different algorithms at different complexity classes (O(1), O(log n), O(n), O(n log n), O(n^2)). Benchmark each with Ruby's Benchmark module …
7 lessons. Read in order; spiral back when you need to. By the end you'll have used the core ideas twice — once on the abstract, once on something you'll meet at work next week.
