Ask HN: Does this exist? (micro open-source)

I just wrote a pair of extension methods in C# to get or set a series of bits from a ulong. This must have been done thousands of times by other devs. I have done it a few times myself. I know I have it somewhere in another project, but I don't feel like hunting to find it. It's not an amazing feature, just a small thing I need. It really doesn't have a place in a library, it's a small stop-gap; like thousands of other small stop-gaps we all write into our projects. I don't know whether or not the technique I used is the fastest possible; at the moment I don't really care. I needed something quick, and I wrote it. It will probably never get replaced, as it will never show up on a hot-path when profiling. I'd like to know if there is a place I can put little things like this, with a way to find little things like this placed there by others. I'd imagine you'd need to come up with a way of describing your method in a verbose way so it can be found. If I use one of these small methods from that place, and that method is improved by someone else, I'd like to be automatically notified that there is a better solution so I can go back and replace mine. Does something like this exist? If not, who wants to build it (I'm busy)? Hey there stackoverflow. This might be right up your alley.
