I'm a so called "scientific" programmer, meaning that I use programming as a problem solving tool, and not to create software for others to use. Programming is a lot easier when you're the only user. Here are some items:
* A ransomware detector based on accessing my home network file server via an all-Linux chain that stores file hashes and watches for changes.
* Converting PayPal transaction history from PDF to the numbers needed for my tax return, and some similar tax related scripts.
* Anything involving measurement or data logging, such as temperature, etc. During one episode, I sorted out whether my home furnace was operating intermittently.
I won't count hobby related stuff, which is innumerable.
