Welcome to the PKB | #!/bin/coding

This is the Public Knowledge Base — short, evergreen reference notes I've written for myself that are also useful in the open. Unlike the blog, notes here aren't dated narrative posts; they're reference material I expect to revisit and edit over time.

If you spot something wrong, let me know.

Code blocks render with syntax highlighting

The site already loads highlight.js on every page (GitHub-dark theme). Any fenced code block with a language tag picks it up automatically.

Bash

# Find all containers consuming more than 256 MiB
kubectl top pods --all-namespaces \
  | awk '$4 ~ /Mi/ && $4+0 > 256 { print }'

JavaScript

/**
 * Tail-recursive flatten — handles arbitrarily nested arrays without
 * blowing the stack on V8.
 */
function flatten(input) {
  const stack = [...input]
  const out = []
  while (stack.length) {
    const next = stack.pop()
    if (Array.isArray(next)) stack.push(...next)
    else out.unshift(next)
  }
  return out
}

Go

package main

import "fmt"

func main() {
    nums := []int{1, 2, 3, 4, 5}
    sum := 0
    for _, n := range nums {
        sum += n
    }
    fmt.Println("sum:", sum)
}

YAML

apiVersion: apps/v1
kind: Deployment
metadata:
  name: hello
spec:
  replicas: 2
  selector:
    matchLabels: { app: hello }
  template:
    metadata:
      labels: { app: hello }
    spec:
      containers:
        - name: hello
          image: nginx:alpine
          ports:
            - containerPort: 80

Inline `code`

You can also use inline code — it gets the same monospace treatment but skips the highlighter, since there's no language to detect on a single token.

What goes here

Loose rule of thumb:

Notes — short ("how do I quickly grep across all my running pods?")
Cheatsheets — commands I look up often enough to forget
Postmortems-lite — small gotchas, not full incidents
Snippets — code I want to keep handy without spinning up a gist

That's it. If you're looking for longer-form writing, the blog is the right place.
