Self-hosted Let Me Google That For You (LMGTFY) service.
If someone asks a question that can be easily answered by a search engine, you can use this service to generate a link that will show them how to do it.
Use the URL https://lmgtfy.linu.sk?q=QUERY and replace QUERY with the search query you want to show them how to search for.
If you want to self-host this service, you just need to clone this repository and serve it using any web server (nginx, apache, caddy, python3 -m http.server, ...).
