In the last few years, JavaScript has become the main tool to build rich web applications. But it has also shown some of its limitation. The nature of the language makes it so that very little tools have been provided to the developer for dynamic analysis.  Last September,  we started a research track to improve productivity of Javascript developers. Professor Koushik Sen from UC Berkeley has been working with our Lab team - to develop a framework to tackle this specific issue. The result is Jalangi. It is short for JAvascript LANguage INtelligence and it is also an Indian river which is a branch of the Ganges.
Jalangi is a framework that annotates and monitors JavaScript programs and can be used for running analysis dealing with validation/monitoring/debugging,etc...It provides a general framework that can be extended with plug-ins.It is already implementing a few analysis tools such as selective record-and-play, taint analysis or the ability to infer likely types of objects fields and functions. More  interestingly, one of the plugin provides the first thorough implementation -as far as we know - of concolic testing for Javascript. Concolic testing is a mixture of  concrete execution (using particular concrete values as inputs) with symbolic execution - which treats program variables as symbolic variables. The symbolic execution piggy-backs on the concrete execution through instrumentalization of  the code. You basically identify through this method what are the concrete input values that allows you to comb through all the branches of the code. It provides a great tool to generate automatic test cases with high level coverage.
Bear in mind that all this is just the beginning, the idea of Jalangi is precisely to provide a framework to foster innovation in the area of JavaScript tools and productivity. There will be more things coming up. I will keep you posted. That is precisely why it has the architecture it has and why it is open source and can be found on github (https://github.com/SRA-SiliconValley/jalangi)
And since it is open source, you are welcome to join the fun and contribute! Send us feedback! Hope you like it.
PS: our team is presenting a paper on some aspects of Jalangi at ESEC/FSE 2013 in August in Saint Petersburg, Russia.

OpenRepos replaces MeeGo OBS with repositories for community apps

Basil Semuonov has posted to TMO to launch a new service for developers: "Remember the sweet holy time when Meego OBS was alive, and you had your very own personal repository? Well, that awesome time has returned!"

"OpenRepos is a community driven personal repository system for Harmattan and Sailfish operating systems. It provides a repository which can be enabled on your device."

The project still seems to be bootstrapping itself at the moment, but has a laudable goal. It would be good to see this combined, though, with existing efforts on a maemo.org OBS and fit into the existing maemo.org repository system; expanding it to support Harmattan - although that might leave Sailfish a little underhandled.

As you have probably heard on Twitter from the official Jolla account, the first Jolla will ship with Wayland. In that discussion, some worries are brought up about Python support with Qt 5. Here are my personal thoughts of how I see mobile Python development moving forward with the new technology. So first some background information:

The incoming Hildon Foundation Board of Directors held their first meeting on Tuesday July 16th, 2013 at 19:09 UTC. The meeting was held in #maemo-meeting on the Freenode IRC network. A voice meeting to make it official by Pennsylvania incorporation laws was also held.

Over recent years, libferris has been using Qt to mount some Web stuff as a filesystem. I have a subclass of QIODevice which acts as an intermediary to allow one to write to a std::ostream and stream that data to the Web, over a POST for example. For those interested, that code is in Ferris/FerrisQt.cpp of the tarball. It's a bit of a shame that Qt heavy web code isn't in KIO or that the two virtual filesystems are not closer linked, but I digress.

Hildon Foundation Board minutes for meeting on July 16th

The Hildon Foundation is the relatively new body which has taken on legal responsiblity for maemo.org from Nokia. The newest, recently elected, board had their first meeting on IRC to appoint Andrew Flegg as Chair, Craig Woodward as Secretary, win7mac as Treasurer and Ryan Abel as Comms Officer. Rüdiger Schiller is also on the board.

The meeting was a fairly run-of-the-mill handover meeting, focusing on logistics; with Joerg Reisenweber representing the Council and, thus, the users of maemo.org. Unfortunately, due to an administrative oversight, the meeting wasn't pre-announced, but this will be corrected for the next meeting.
