In a world obsessed with AI hype, Codeforces remains the purest meritocracy in software: a battlefield where millions of lines of code are judged by a single, unforgiving metric—execution speed. Here, your logic either holds up under pressure, or it breaks.

"Codeforces doesn't teach you syntax; it teaches you how to think under extreme computational constraints."

The tech stack tells a story of modern resilience: Ruby on Rails powers the backend, while Cloudflare and HSTS ensure the platform remains secure and performant under the load of millions of concurrent submissions. It’s a classic, robust stack that prioritizes reliability over bleeding-edge experimentation—exactly what you want in a competition platform where a millisecond of downtime can ruin a contest.

• **Pure Meritocracy:** Rankings are determined solely by algorithmic efficiency, not popularity or networking.
• **Community-Driven:** The blog (entry/150351) acts as a central nervous system for announcements and discussion.
• **High-Stakes Environment:** The platform simulates real-world pressure, training developers for FAANG-level technical interviews.
