I’m not sure what I’m doing here or whether this makes any sense, but I thought I make it possible for someone to buy me a coffee, if they find my projects useful! As for what I do. I’m a researcher, and a software developer. Often, as I’m working on my main projects, I develop smaller projects. So, I thought maybe it is not a bad idea to make habit of spending a weekend or two polishing and open-sourcing them.
