https://www.eyedex.org/ It's an open directory search engine I have been slowly cooking on the side for past one and a half year. Basically an open directory is a webpage on the internet with autoindex set to on - it lists files and directories on server with some metadata. The real reason why I built it was to learn PostgreSQL together with some text searching functionality, so far it has been really fun experience. Another reason was that there haven't been sites like this, most of them are shameless redirects to google dorks or just straight up amateur jobs. What mine does differently is take care of file metadata and allows to order/filter by it, which narrows down searches quickly. I really don't care if it succeeds or no, there is no money in it, I don't really care anyways. It kinda scratches the itch about what great services can be build on good old internet and if it's useful for a few people out there, even better.
