Introduction This article is the 6th installment of the CS Roadmap series. In Part 1, we saw the 100x difference between L1 cache (~1ns) and RAM (~100ns). We also saw that cache locality is t...

Introduction This article is the 5th installment of the CS Roadmap series. In Part 4, we saw how trees guarantee O(log n) through hierarchical structure. BSTs search while maintaining order, ...

Introduction Claude Code’s Skills system has received a major update. What was once a simple structure — writing instructions in a single SKILL.md file — has evolved into a complete skill developm...

Introduction This article is the 4th installment of the CS Roadmap series. In Part 3, we saw that hash tables’ O(1) doesn’t come for free. Hash function quality, collision resolution strategi...

Introduction This article is the 3rd installment of the CS Roadmap series. “Find the value for this key.” This is the most frequent question in programming. Looking up stats by monster ID, r...

Introduction This article is the 2nd installment of the CS Roadmap series. In Part 1, we examined arrays and linked lists from a memory perspective. Arrays dominate the cache through the powe...

Introduction This is the first installment of the CS Roadmap series. When you start programming, everyone learns arrays. Write int arr[10] and you get space for 10 integers. Next comes the li...

Introduction When working with C# projects in Claude Code, there are two main tools available: csharp-ls (LSP) and JetBrains Rider MCP. Both help with code analysis, but their mechanisms and effic...
