I'm Learning DSA by Teaching It And I Want Your Feedback
Hey everyone! 👋 I’ve recently started explaining DSA problems on my personal YouTube channel. While solving DSA problems, I realized something: Unde…
I spent months building an exact incremental-computation library in C. I finally put the reproducible benchmarks on GitHub.
I’ve been working on a performance project called HKD Kernel. The premise is that a lot of large computations repeat work unnecessarily. If only a t…
Designing Algorithms That Adapt to Their Input Distribution
Most algorithms are taught as if the input were some abstract thing that simply arrives at the function boundary. An array appears. A graph appears.…
Algorithmic Patterns: The Ultimate Guide to Sliding Window
The Sliding Window pattern is one of the most vital algorithmic techniques for optimizing array and string problems. Instead of repeatedly processin…
I built a content recommender as a graph, and it found similarities I wasn't looking for
Most beginner recommendation projects are a dictionary lookup. You type "comedy", it returns the comedy list. That works, and it is also the reason…
Why I use reconstruction puzzles to keep interview algorithms fresh
The hardest part of algorithm interview prep was not learning binary search or two pointers for the first time. It was opening an old problem months…
