If you modify the compiler, you have to redistrbute the source indeed. Notice the compiler does not include the standard library and the backends (native/node)

The Opa compiler will remain an AGPL project. The standard library and the native backend will be licensed under the GPL license with the so-called ClassPath exception, like Java. The exception means you can link the GPL code with any code, opening the door to license your application under any license. The forthcoming Node.js backend will be licensed under the MIT license.

Very good idea for the chapter about Opa for OO dummies. You are absolutely right ;)

One of the part of Opa is it's type inference, so you still can write JavaScript like code, but with the type being infered without the need to precise it most of the time.

Submission + - Opa 1.0 Released (opalang.org)

Submitted by phy_si_kal on Thursday June 21, 2012 @11:25AM

phy_si_kal writes: The open source Opa project just released its 1.0 version. Opa appeared last year and was discussed a few times.

Throughout the year, Opa adopted a JavaScript-like syntax, gained support for MongoDB and now Node.js.
Opa positions itself as the enterprise JavaScript framework due to the safety and security provided by its strong static typing system.

Indeed, Opa checks the type safety of the application over the whole application, from client, to server, to database. Opa also provides many automation algorithms, such as the automated use of Node.js fibers at runtime, automated client/server and server/database dialog.

The site of the project also announces a developer challenge.

Hugh Pickens writes writes: "Christopher Shea writes in the WSJ that physicists studying Google's massive collection of scanned books claim to have identified universal laws governing the birth, life course and death of words marking an advance in a new field dubbed "Culturomics": the application of data-crunching to subjects typically considered part of the humanities. Published in Science, their paper gives the best-yet estimate of the true number of words in English—a million, far more than any dictionary has recorded (the 2002 Webster's Third New International Dictionary has 348,000) with more than half of the language considered "dark matter" that has evaded standard dictionaries (PDF). The paper tracked word usage through time (each year, for instance, 1% of the world's English-speaking population switches from "sneaked" to "snuck") and found that English continues to grow at a rate of 8,500 new words a year. However the growth rate is slowing, partly because the language is already so rich, the "marginal utility" of new words is declining. Another discovery is that the death rates for words is rising, largely as a matter of homogenization as regional words disappear and spell-checking programs and vigilant copy editors choke off the chaotic variety of words much more quickly, in effect speeding up the natural selection of words. The authors also identified a universal "tipping point" in the life cycle of new words: Roughly 30 to 50 years after their birth, words either enter the long-term lexicon or tumble off a cliff into disuse and go "23 skidoo" as children either accept or reject their parents' coinages."

Submission + - New Opa S4 release puts forward new "ORM" for MongoDB (opalang.org)

Submitted by phy_si_kal on Tuesday February 21, 2012 @10:44AM

phy_si_kal writes: The new, open source, Opa web programming language just hit version 0.9.0 "S4", six month after its last major release.
Apart from a new syntax more similar to JavaScript, the new releases focuses on mongoDB integration.
Opa now features something similar to ORM except that mongoDB is a non-relational, document-oriented database and Opa a functional, non-object-oriented language.
The new functionality makes the NoSQL database even easier to use as all language-database calls are automated. And the mapping of functional datastructures to documents could even be much better than current ORM approaches and solve the object-relational impedance mismatch.

Why should you care about yet another language? There are few things that make Opa stand out from the crowd:

it's a language targeted at the web;
it puts lots of emphasis on security;
it's a one-stop solution; you write in Opa and it generates for you: the client-side code (JavaScript), database queries, all the glue code etc.
scalability won't be a problem: your app is distributed and cloud-ready right from the start.

Curious? Sounds too good to be true? Check out Opa's homepage or my blog for more info.

Submission + - A new, original, open source web tech is born (opalang.org) 1

Submitted by phy_si_kal on Thursday May 19, 2011 @04:30PM

phy_si_kal writes: Today, a secretive startup from Paris, France has announced that it will open source the Opa technology it has been developing for some time.
Opa is a one-tier web technology (right, that means only one layer at runtime) where Opa source code is compiled into a standalone binary. And, this could be really a game changer in the cloud era as it handles distribution very easily.
Sadly, the code is not yet available but a 171-page manual and tutorial is already available (registration required) and packages seem on the wild.
