I'm not sure why you should learn ruby only if you do web things. Is it true ? Is ruby only useful in web projects ?

Does this assume you already know C or that you shouldn't learn vanilla C?

(I am the creator of that graph) It sort of assumes that you already know C. Back when I started studying software development, C was the starter language, the one language that every one in engineering knew, even if you continued your studies in, for instance, chemistry. I suppose that is no longer the case, though.

There are many hidden assumptions in that graph, which is probably the reason why it stirred up so much discussion.

That's a really weird way to draw a decision graph.

I know, but it was the quickest way to create it. Do you have a good suggestion for an open source Visio-like program? I've tried numerous, but all their interfaces are terrible and their standard shapes and icons aren't very attractive.

What's so adventurous about Go? Few libraries?

This graphic is obviously wrong, since Scala is in it, and as we all know, Scala is like EJB2 and the next big language is going to be Fantom.

LOL
