    Also about once a year, I get a letter from a lawyer, every year a different lawyer, at a company -- I don't want to embarrass the company by saying their name, so I'll just say their initials -- IBM [laughter] saying that they want to use something I wrote.

    Because I put this on everything I write, now. They want to use something that I wrote in something that they wrote, and they were pretty sure they weren't going to use it for evil, but they couldn't say for sure about their customers. So could I give them a special license for that?

    Of course. So I wrote back -- this happened literally two weeks ago -- "I give permission for IBM, its customers, partners, and minions, to use JSLint for evil."

    [laughter and applause]

    And the attorney wrote back and said: "Thanks very much, Douglas!"
