General Development "Opa, a new opensource programming language aiming to make web development transparent has been publicly launched. Opa automatically generates client-side Javascript and handles communication and session control. The ultimate goal of this project is to allow writing distributed web applications using a single programming language to code application logics, database queries and user interfaces. Among existing applications already developed in Opa, some are worth a look. Best place to start is the project homepage which contains extensive documentation while the code of the technology is on GitHub. A programming challenge ends October 17th." This is weird. 'Opa' is the nickname my friends gave me 6 years ago. It's still used more often than my actual name...

RE[2]: What's the Problem

The problem with the license is that it doesn't fit with the commercials of how I do the web.

Typically I grind away for a couple of months, building something neat, then release it, and it either flops or gets some traction. If the latter I find some money to throw at taking it more seriously.

The license as I read it is incompatible with this. Either I have to release my source code from day 1, or I have to pay from day 1. If the former, then I've got virtually no defendability, if the latter then I can't afford to use it. So it just doesn't work out for me beyond messing about.

Although AGPL is used for Mongo, this is a different kettle of fish, because with a DB, there is a fire-break at the interface (and the Mongo interfaces are Apache licensed). I don't have to share my application code with the world, only stuff I do to Mongo itself (which I'd imagine almost nobody ever does).

In short AGPL for a programming language is always going to seriously hurt, if not totally torpedo adoption. But obviously a BSD-style license isn't painful enough to encourage many to pay you. Its a catch-22. But I suspect you'll probably end up being forced to use a more liberal license in due course, to encourage great apps to be written which in turn will raise Opa's profile. The ultimate aim has to be for a big-huge-web-success-story to say "We built our system on Opa", and a company that you can provide vast amounts of training, consultancy and support for - that, I think, is a numbers game, ubiquity is more important than incremental revenue at this stage, imho.

Now a few more days into playing with Opa, and I do think it has some very strong points. I also very much like the effort that has gone into documentation. It is an impressive package.
