on saying hello

1. Introduction

Hello, world. This is the first document in the series, mostly to check that everything renders.

2. Scope

Documents in this blog cover infrastructure, networking, observability, and computer systems. An Atom feed lists published documents.

3. Reference Implementation

#include <stdio.h>

int main(void) {
  printf("hello, world\n");
  return 0;
}

4. Acknowledgements

The blog itself was built by Devin. All words and opinions are mine, however.
