+ - Opa JS Framework Hits Major Milestone->

Submitted by phy_si_kal
phy_si_kal writes: The Opa Framework allows to build JavaScript applications that run on NodeJS and MongoDB.
Since its 1.0 release, the Opa framework has switched to a more liberal MIT License and was a finalist of GigaOM's Structure 2012.
The project hit today a major milestone, releasing a version which is 38% smaller, generates 62% smaller apps, that run 49% faster while using 29% less memory.
That's good news before the Opa Developer Challenge ends.

+ - Opa 1.0 Released->

Submitted by phy_si_kal
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.

+ - New Opa S4 release puts forward new "ORM" for MongoDB->

Submitted by phy_si_kal
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.

+ - Announcing Opa: Making web programming transparent->

Submitted by phy_si_kal
phy_si_kal writes: 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.

+ - A major new project hits github

Submitted by phy_si_kal
phy_si_kal writes: Opa source code has just hit github!
This new programming language makes tierless web applications and webservices. It basically means that the project is a complete rewrite of the whole server stack and that it does not rely on any existing web server or database server: Web applications are compiled into standalone servers, that can run on bare linux distributions.
Opa is a single programming language for both the server and the client, as the compiler generates Javascript code for the client side and automates the calls between the two.
Event-based programming is natively supported (20 LoCs for a webchat) as well as distribution (1 shell command to run on many servers).
Packages, documentation and standard library browser live there.

+ - A new, original, open source web tech is born-> 1

Submitted by phy_si_kal
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.
Disclaimer: I am at MLstate (and very happy)

+ - What open source licenses are you ok with?->

Submitted by phy_si_kal
phy_si_kal writes: We are about to launch a new programming language, built for the web. Crowded space, but we think we have what it takes.
Time to choose the open source license. What do you think? Should be go copyleft all the way, to encourage contributing back? Or non-copyleft to appeal commercial users? We have made a survey for this (results are public of course).
