Plenty as a matter of fact. Two large ones off the top of my head. First one: cloud services are expensive and come with a lot of overhead. However I do enjoy the idea of lambda/cloud functions a lot but I didn't want to rely on cloud services for them, especially since I have a ton of hardware to self-host stuff. So I built a service which piggybacks on DIND where I could add templates for such lambdas for a few languages(just rust and python cause that's mostly what I use) where I can allocate some resources and build tiny containers. In order to avoid wasting resources, they are all off by default but through the magic of what I build(management and something like a reverse proxy + container management for DIND), I can call an endpoint, which will check if there is a container to handle the requests and proxies the request and response to and from it or it will spin up the container, do the same and shut it down after a pre-defined amount of time. You could argue that I could have achieved the same with minikube or k3s but this has proven to use a lot more resources compared to a single rust binary I can run on anything x86 with docker on it. The downsides are that I can't distribute it across multiple servers so it only runs locally. But that fits my needs perfectly. There might be some people that would be interested in it but I never got to open sourcing it so I'm the only user. I've been planning to open source it "next week" for the past 2 years or so. Second one: I love data. Specifically unstructured, raw data and I've been collecting a ton of articles from the internet over the past 2 years or so. The ingestion involves a pipeline that automatically processes them and extracts data/makes them a lot less unstructured: events, locations, timestamps, what has happened where and all that jazz. It's a long list of ml models, data transformations, validations, 3 llm's fighting each-other and a bunch of other stuff. Kinda feels like a child to me so I don't want to open source it. I know that I could hypothetically convert it into a product and make some money off it but my past entrepreneurial experiences have been very unsuccessful, I have limited time and lack motivation. So at the moment I'm simply enjoying the data getting spit out on a grafana dashboard such as this [1]. [1] https://i.imgur.com/fAoQghk.png https://i.imgur.com/fAoQghk.png
