About the Google Summer of Code
From the Google Summer of Code 2013 webpage:
Google Summer of Code is a global program that offers student developers stipends to write code for various open source software projects. We work with many open source, free software, and technology-related groups to identify and fund projects over a three month period. Since its inception in 2005, the program has brought together nearly 6,000 successful student participants and over 3000 mentors from over 100 countries worldwide, all for the love of code.
Through Google Summer of Code, accepted student applicants are paired with a mentor or mentors from the participating projects, thus gaining exposure to real-world software development scenarios and the opportunity for employment in areas related to their academic pursuits. In turn, the participating projects are able to more easily identify and bring in new developers. Best of all, more source code is created and released for the use and benefit of all.

GSoC Project Ideas 2013
Distributed node monitoring and management application
We use different monitoring systems but we are not completely satisfied with any of them.
Problems we face:
- Different monitoring systems are hard to maintain. When we change anything in our network we have to remember to change also the information in all the systems we use
- One of the systems is proprietary, closed source and it works only with a very limited set of devices
- We need to be able to diagnose problems quickly with a cross check on different protocols (SNMP, OLSR, BATMAN)
- We need more flexibility
- We need a decentralized system
- We want it Open Source
- We need network usage and traffic graphs
- Develop a new pluggable distributed app for the map-server which can be deployed in different parts of the network which automatize the synchronization of the operations and eases our pain in the management of our network.
- Maybe instead of reinventing the wheel we could integrate one of the existing open source monitoring applications with our map-server, the integration should take care of synchronizing the several systems in use.
Level 4: Web Developer
Frameworks: Django, jQuery
Filesharing suitable for Community Networks
Many people want to share files in our community network but they step into some problems:
- Existent major P2P solutions depend on the Internet ( like emule or torrent )
- Most of major existent P2P solutions doesn't support ipv6
- Folder sharing like samba doesn't provide efficient file search
- People prefer to share depending on relationships, for example you want share some photos with your school companion but not with your headmaster.
- Internet bandwidth on our network is going towards exhaustion
RetroShare cover just a part of our needs
To solve these issues we need to:
Add group support to RetroShare
- File access policy is strongly based on users groups.
Add ipV6 support to RetroShare
Level 4: Semi-Professional
Videoconferencing suitable for Mobile Phone and Mesh Networks (MPMN )
Many people want to use VOIP in our mesh network but they step into some problems:
- Existent major videoconferencing solutions depend on the Internet ( like skype or gtalk )
- Most of major existent videoconferencing solutions have not a good mobile phone integration ( like skype )
- Most of major existent videoconferencing solutions don't have support for ipv6 ( our network is primarily ipv6 )
- Internet bandwidth on our network is going towards exhaustion
- They doen't want to learn to use another VOIP app
To solve these issues we decided to implement Videoconferencing suitable for Mobile Phone and Mesh Networks:
- Create a good app, fully integrated in android/iphone/(other?) addressbook ( call someone trough MMPN must me simple as call him with phone number without learn to use other apps or have different gui).
- Separate MMPN backend from addressbook integration ( like telepathy framework do on desktop ).
- Make the backend extensible for newer protocols
- Offer good privacy with encryption
- Preferable completely serverless protocol such as retroshare
Level 4: Semi-Professional
Collaborative Music Composition
This project aims to realize a web-based social application for music composition.
It will allow the creation of jam session (non real-time) in this way: users will upload tracks (e.g. piano track) and then they can merge them with other tracks (e.g. bass track) that other users pushed in the system. Users can play a bunch of selected tracks creating a composition (e.g. bass+piano+vocal).
Using the linux audio plugin and a proper backend engine, they can also apply effects on tracks.
Conversely, if a user doesn't like an instrument track of a song, he can create his own version by substituting it with her own track.
It will use a web framework such as Django to manage users, file upload and dynamic content.
On the backend it will handle files using linux programs. It could add effects (such as reverb or delay) on tracks by interfacing with a LADSA compatible command line script. In this way we will reuse the tons of linux audio plugin.
Every track is under a kind version control (git or whatever) so to keep track of branches and merges. Git seems not suitable for http://stackoverflow.com/questions/984707/what-are-the-git-limits.
- Given the heavy burden on the server that the server should manage, a cloud solution can be investigated. For instance we can use Ubuntu Orchestra and Juju.
Improve the ninuxoo search engine
We have started the development of a community-network-wide open-source search engine called ninuxoo. Written in Python, it is formed by a samba and ftp share crawler and of a cgi-based website, with a common database. We would like to enhance it by adding some features:
- show results whith a number of hops distance, based on the IP address of the user that is performing the search. This needs to interact with the routing daemon (i.e. olsrd in our case) by periodically retrieving the graph of the community network (through the txtinfo or dot olsrd plugins) and running standard graph search algorithms (e.g. Dijkstra's)
add a "what's new" web page that shows the newest files found by the crawler. This needs changes to the database schema
- reengineer the ftp crawling code
Programming Languages: python, mysql
Maturing external application APIs and introducing Event managing support for DIASPORA* Distributed Social Network
Diaspora is a free and open source application implementing a distributed social networking service which is made out of “pods” (i.e. servers), which in contrast with the centralized approach can be run directly from the users who can have full control of their online identity thus allowing information not to be controlled by a single party. Furthermore communications and content sharing between users are secured by the Salmon protocol.
The project is still inching towards a first beta release and at the moment lacks a mature API set which would be vital for the growth of the project itself as it would allow the development of external applications by independent developers who want to exploit the power and the possibilities provided by such platform. As of now, only the draft of a preliminary version of the basic APIs is available (Reference ). This project aims at developing a REST application API set that will provide developers with endpoints to the core functionalities of the social network, allowing them to manage the social graph with objects representing the main 4 Diaspora resources (People, Aspects, Posts, and Comments) and the connections between them (e.g., friend relationships, shared content, and photos).
Furthermore, an external application that will interoperate with D* will be developed on it as a proof of concept. This application will aim at providing Event managing support for the users as an external service that will allow the community to create and manage events, invite other users to them and publish related content.
PGP cryptography plugin for Jitsi
http://jitsi.org/ is a promising IM software with builtin support for audio/video calls and conferences, desktop share, remote control and OTR cryptography.
We already use PGP to encrypt sensitive emails that contain login information to critical parts of our network, we developed a good web of trust and for this reason we would prefer PGP to OTR for our sensitive communications.
Since Jitsi is pluggable, this feature could be added as an additional plugin.
Technologies Java, OpenPGP
Suppose you are the only one user of a large wireless mesh network. If you had several Internet gateway, how could use use all the bandwidth of all those gateway in order to download your files faster? Build the solution!
Our idea is to realize a module that take packets and send them to internet using multiple gateway via the Loose Source Routing option of the IP packet. With that option you can force packets to pass to one or serveral different router! Conversely nowadays packets usually do the same path to reach a destination, so if you are alone on a WCN with several internet gateway, right now you are doomed to use only the bandwidth of one gateway, typically the nearest one. Whereas the iptables target is not yet supported to put the loose source routing option, this option is supported by the Linux kernel.
improve this software to add the Loose Source Routing target to iptable
- develop a software/script that take a list of gateway and send packets to them according to a given policy (round robin, using connection track etc)
- develop a script that takes olsr information and populates the gateway list of the former point.
Ninux's nodes are installed on the private roofs. Electronics devices (Poe power supply, ethernet switch etc...) are in a waterproof box closed to antennas mast. Due monitoring harware integrity against unauthorized access at the box,cable cutting and vandalism, we need a utility running on very low cost SoC (requirement: TCP Stack, Ethernet port and some GPIO for the sensor) integreted with our network monitoring.
- Indentify the platform: cheap, simple to found in electronics stores,support Open Source (uclinux, Arduino etc...), Ethernet interface, accessible GPIO (at least 4), small size.
- The sensors to manage: door sensor, cable cutting sensor, proximity sensor, shake sensor via GPIO.
- Interfacing data with SNMP protocol.
- Develop a plugin for Nagios and/or AirOS for manage the alarms.
Background: lots of cheap but good enough "plug computers" are available; they are perfect for home servers, but there is nothing that will fit Average Joe.
The idea is to do a little step towards the goal of realizing it: not a complete distribution that will fit every scenario, but a simple way to manage some service and configuration files through a web UI. The focus is on privacy related services (tor relay, privoxy, polipo, firewall) and basic networking (network configuration, dhcp/dns server) but of course there is room for everything.
- Make some configuration tools
- Make a middleware to manage configuration tools better
- Make a WebUI for the middleware
- Make this simple to install on a standard debian distribution (or openwrt)
MilkFish for Unistim
It's easy to find very cheap used Nortel Phones that work well with asterisk unistim channel. MilkFish is a VOIP proxy using SIP protocol (http://www2.milkfish.org.sipwerk.com/). The idea is to port asterisk unistim channel to Milkfish. The requirements are:
- Small footprint for embedded system
- Same functions of original project
