I've noticed that you didn't put any open-source license with your code, which is understandable since it's your first. :)

So my question (likely to others) is this: when you do that kind of week-end projects, do you put a license with it and if so, which one?

The reason I'm asking is I also put some code on GitHub from little projects, but without any license for now, mostly because I didn't really care either way. But I imagine it'd make sense to know about a few good ones to go with and use that for most cases. (for example, it seems to me that the MIT license has got some popularity over the GPL, but I'm not sure why)
