I have two! https://gifmemes.io, haven't touched the code for years, makes between 100-300$ a month, depending on the season. https://vocabuo.com - a side project I hope to turn into a business, so I work on it around two days a week, made around $3.5k in revenue last month but most of it went back into ads. - Source: Hacker News / 5 months ago

We then implemented a self hosted version of OSRM and let me tell you, it did the hard math for us, our code only took like 5s, we could do it on the fly whenever a new intervention was scheduled. Source: over 2 years ago

I am trying (and failing) to setup an OSRM instance with docker compose. The issue I've encountered is with setting up osrm-backend. According to the Github and Docker Hub pages, the process is as follows:. Source: over 2 years ago
