Submission + - Announcing Opa: Making web programming transparent (lambda-the-ultimate.org)

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.

Submission + - A major new project hits github

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.

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

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)
