This page will list of collections that could be useful for me in anything. Maybe it is not for you, but I use it a lot. Some of these things might appear on another place, because I also use them and save it, but who would cares anyway.
Honestly, people nowadays would prefer to write web apps rather than software since it is easier to do so and harder to pirate. Also, it attracts and centralizes your works together.
Please note that some links could be dead as well. Archive it with archive.is before it is too late. For database query, there is nothing much we can do. Also, please give a feedback/issues on GitHub. This data will be updated based on my interests, since I don’t have time.
