I am doing a short talk about a cryptographic paper to a reading group. In explaining the paper I wanted to use a UML Sequence diagram (I have invested enough in UML that I even dream in UML sequence diagrams sometimes).¹

So in order to do this I needed a free easy to use editor. Google (everyones friend) helped me out nicely and I found Violet. Violet is a great free easy to use tool. It just works, and makes it easy to do the straightforward uml diagrams. I only did a sequence diagram, but found it did the job very well. I kicked it off with Java Web Start, and then exported the image the hacky way with alt print screen. 30 seconds of Paint gives me a nice little diagram that contains my understanding of the game playing technique.

It looks like this:

^1. When learning a foreign language the evidences that you know the language well are:

• that you think in the language,
• dream in the language, and
• that you can do things like pray in the language.

As I mentioned, I have had dreams in UML, and often think in UML. I cannot pray in UML, but could probably explain Christianity in a sequence diagram.
