I have not decided on a license for code published on this blog, although WTFPL looks pretty close to what I’m after. Basically, if I wanted to prevent my code from being used, I would not publish it on a blog. So, if you want to use my work in some serious project, you should contact me to get proper permission. Chances are, I’ll give you permission, with the sole requirement that you include my name in an acknowledgment somewhere (since that’s the decent thing to do anyway).
I will have a contact page eventually; for now, you can just leave a comment.
