SERVICES AND INFRASTRUCTURE
Updated July 25, 2026

I run a collection of public applications, classic Internet protocol
servers, APIs, monitoring tools, and event-driven backend services.

--- Public Services ------------------------------------------------------

Random Steam Game
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 exclusions and filters, 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

--- QOTD ------------------------------------------------------------------

HappyQOTD
qotd.kgivler.com - TCP port 17
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 for hierarchical menus, text files, downloads, and compiled
dynamic pages. It provides a text-first alternative to the modern web.

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 a 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


--- Mission Control -----------------------------------------------------

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 keeps a durable SQLite
history of received events.


Mission Control GitActivity

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


RabbitMQ

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


--- Operations/Monitoring -------------------------------------------------

Beszel

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


Uptime Kuma

Performs scheduled availability checks against websites, APIs, and classic
protocol services. It verifies that services are reachable rather than merely
that their containers are running.


--- Notes -----------------------------------------------------------------

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

Most of the Happy protocol servers are written in C# and .NET 10 and publish
best-effort operational telemetry to Mission Control.
