SERVICES AND INFRASTRUCTURE
Updated August 8, 2026

--- PUBLIC SERVICES ----------------------------

Random Steam Game Picker

https://randomsteam.kgivler.com/

A fast random game picker for public Steam
libraries. It resolves a Steam account, loads the
user's owned games, applies filters and exclusions,
and selects a random game.

--- ECHO ---------------------------------------

HappyEcho
echo.kgivler.com
TCP port 7

A modern implementation of the classic Echo
protocol. Every byte sent to the server is returned
unchanged.

Try it:

printf "hello\r\n" | nc echo.kgivler.com 7

--- DISCARD ------------------------------------

HappyDiscard
discard.kgivler.com
TCP port 9

A modern implementation of the classic Discard
protocol. The server accepts incoming bytes and
intentionally throws them away without returning
a response.

Try it:

printf "throw this away\r\n" |
nc -w 2 discard.kgivler.com 9

--- DAYTIME ------------------------------------

HappyDaytime
daytime.kgivler.com
TCP port 13

An implementation of the RFC 867 Daytime protocol.
Each connection receives the current server time
and is then closed.

Try it:

nc daytime.kgivler.com 13

--- QUOTE OF THE DAY ---------------------------

HappyQOTD
qotd.kgivler.com
TCP port 17

HTTP API:
https://qotd-api.kgivler.com/api/quotes/today

A Quote of the Day service with both a classic TCP
endpoint and an HTTP JSON API.

The TCP service and API return the same persisted
quote for the current UTC day.

Try it:

nc qotd.kgivler.com 17

WARNING:

This instance uses my personal, unfiltered quote
collection. Most quotes are programming-related,
but some contain strong or obscene language or
discuss suicide and other sensitive subjects.

--- GOPHER -------------------------------------

HappyGopher
gopher://gopher.kgivler.com/
TCP port 70

A Gopher server written in C# and .NET. It serves
menus, text files, downloads, and compiled dynamic
pages.

This gopherhole is running on it right now.

Try it:

curl gopher://gopher.kgivler.com/

--- FINGER -------------------------------------

HappyFinger
finger.kgivler.com
TCP port 79

A Finger protocol server with file-backed records,
traditional .plan support, and Random Steam Game
integration.

A public 17-digit Steam ID can be used as the
Finger username to receive a random game
recommendation.

Try it:

finger kyle@finger.kgivler.com

finger [STEAM_ID]@finger.kgivler.com

Get a random steam game from my library:
finger 76561197988408972@finger.kgivler.com

--- MISSION CONTROL ----------------------------

Mission Control is my small event-driven
observability system used by the Happy services
and several other projects.

Mission Control Gateway

Receives integration events and signed GitHub
webhooks, validates them, and publishes a common
event envelope to RabbitMQ.

Mission Control Archive

Consumes the complete Mission Control event stream
and stores a durable SQLite history of received
events.

Mission Control GitActivity

Consumes GitHub push events and creates a
sanitized, website-friendly view of recent commit
activity stored in SQLite.

RabbitMQ

Routes Mission Control events through a topic
exchange to independent durable consumers.

--- OPERATIONS AND MONITORING ------------------

Beszel

A private dashboard for host and container CPU,
memory, network usage, uptime, and status.

Uptime Kuma

Performs scheduled availability checks against
websites, APIs, and classic protocol services.

--- INFRASTRUCTURE -----------------------------

Most of these services run in Docker on a small
VPS in Staten Island, New York.

The Happy protocol servers are primarily written
in C# and .NET and share infrastructure through
JoyfulReaperLib.

Most publish best-effort operational telemetry to
Mission Control.

Public services are exposed selectively.
Administrative dashboards, message broker
interfaces, internal APIs, and most Mission
Control components remain private.

--- CURRENTLY EXPERIMENTING WITH ---------------

HappyGemini

A Gemini server is currently under development as
the next step in my old-protocol and smolweb
experiments. Nothing live yet!

If that goes well, HappySpartan may eventually
follow.
