Handling Optional and Nullable Fields

The API uses the optional package to distinguish between three states for a field in a JSON payload:

Omitted: The field is not present in the JSON request body.
Set to null: The field is present with an explicit null value (e.g., "description": null). This is used to unset or clear a field's value.
Set to a value: The field is present with a non-null value (e.g., "description": "my description" or "description": "").

type Input struct {
	Description optional.String `json:"description"`

Some people run a SOCKS5 proxy locally that proxies their internet traffic through a different location.

To access the proxy via your web browser you can either modify your system-wide proxy settings or use a Google Chrome browser extension, or in the case of Firefox manually configure the proxy settings.

Modify System-Wide Settings

Open System Preferences > Network.

go get -tool github.com/letsencrypt/pebble/v2/cmd/pebble@latest
go tool pebble -version
go tool pebble -config pebble.json
go run main.go

ZoneDB Scripts

This directory contains utility scripts for maintaining and validating the ZoneDB database.

Scripts

`check_domain.sh`

Purpose: Quick DNS resolution checker for individual domains.

Quick Reference Table

Tool	Primary Question it Answers	Best For...
`ping`	"Are you online and can I reach you?"	Basic connectivity checks
`nslookup`	"What's the IP address for this domain?"	Quick, simple DNS lookups, especially on Windows
`host`	"What's the IP/MX record for this domain?"	Clean, easy-to-read DNS lookups
`dig`	"Give me all the DNS details for this domain."	Detailed DNS troubleshooting and scripting
`whois`	"Who owns this domain?"	Finding domain registration and ownership info
`traceroute`	"What network path do my packets take to reach you?"	Diagnosing latency and routing problems

The config file is stored here:

~/.config/humanlog/config.json

The only thing I really configure is formatter.themes.dark.levels.debug.foreground.html_hex_color, which I set to #8CBBFF:

Tip

"I think many people misunderstand the purpose of code review. The purpose of code review is not for the reviewer to find bugs, and certainly not for them to ensure that the code is bug-free. Anyone who depends on code review to find bugs is living in a fool's paradise. As everyone should know by now, it is not in general possible to find bugs by examining the code.

The primary purpose of code review is to find code that will be hard to maintain. The reviewer looks at the code and tries to understand what it is doing and how. If they can't, that means it will be hard to maintain in the future, and should be fixed now, while the original author is still familiar with it." -- https://infosec.exchange/@[email protected]/115096720467521263
