It seems common to run into the problem: "If it's useful, it's probably already made by now." What are some projects one can work on worth more than just showing off?
I've done this with a couple of things which have worked out usable over time and are part of my daily workflow. Most recent is a simplified browser-based replacement for GnuCash which is based on Sqlite and Go. I will publish it on github when I am happy with it.
