Code
N Facts.
We asked.
Why do we build it this way?
The internet is saturated with tutorials that show you what to type. Precious few explain why it compiles, why it's slow, why it collapses under load.
CodeNFacts was born out of frustration. Engineers from systems, compiler, and distributed computing backgrounds were tired of articles that waved their hands at the hard parts.
So we built the publication we always wanted to read. Every article starts from first principles and doesn't stop until the mystery is fully resolved - even if that means reading kernel source code at 2am.
A developer who understands the facts is worth ten who only know the syntax.
Tutorial Hell is Real.
And it's getting worse.
First Principles.
Every single time.
Six promises we
never break.
Silicon-Level Accuracy
From cache lines to compiler optimizations - we trace every abstraction to its bare-metal origin so you understand what's really happening under the hood.
Zero Hand-Waving
Every benchmark is reproducible. Every claim cites primary sources. We never skip the hard parts. Opinion is clearly labeled as such.
Systems Thinking
We connect micro-decisions to macro-consequences. One config line can cascade through your entire distributed system.
Production-Grounded
Our examples are extracted from real incident post-mortems, not toy problems. Learn from failures that cost real companies real money.
First-Principles Pedagogy
We don't teach the shortcut. We teach the long road so you can invent better shortcuts yourself.
Performance as a Feature
We treat milliseconds like money. Every guide includes profiling, measurement methodology, and optimization under real constraints.
Built by engineers.
For engineers.
Every contributor has shipped production code, debugged live incidents, and fought with real hardware constraints. We write from scars, not theory.
