LXDE Google Summer of Code 2010

LXDE is applying as a project for the Google Summer of Code 2010. For students it is a good way to get deeper involved into Free and Open Source Software and LXDE specifically. During the summer students have the chance to code on LXDE and get paid by Google.

Some other projects usually also offer student slots for the LXDE community in the program. We are gathering project ideas, as a way to start for applicants here. If you are interested to join LXDE at the summer of code and would like to discuss project ideas, please join us on IRC at #lxde and on the mailing list:

If you have already an idea about a project you would like to do, please also leave your idea here as well:

Background info on Google Summer of Code

The most common question we get from students is “How do I prepare for Google Summer of Code?” The simple answer is not to wait for the program to get involved in open source. Start checking out projects now: take a look at documentation, check out their source code and idle in some IRC channels to see what interests you. The projects who have been past participants in Google Summer of Code are a great place to start; use the categorized list of mentoring organizations (e.g. projects listed by programming languages) from 2009 to help you get started.

About Google Summer of Code

Google Summer of Code (GSoC) is a global program that offers student developers stipends to write code for various open source software projects. We have worked with several open source, free software, and technology-related groups to identify and fund several projects over a three month period. Since its inception in 2005, the program has brought together nearly 3,400 students and more than more than 3,000 mentors & co-mentors from nearly 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.

Recent Development Status of LXNM

LXNM (Lightweight Network Manager) is working now after a long time for development. If you often check the news of SVN, you can notice that the next generation of LXNM has already supported wireless connection setting, also it has many feature as old version of LXNM. The new implementation and protocol defination seems to work well at least there is no bug of old version of LXDE had that no Access Point was scanned always.

Here is some screenshots to show you current LXNM wireless support:

As a network manager, wireless is the basic feature, but only the feature is not enough for new internet devices. To be a full function network connection utility, it must provide most popular methods of internet connection service something’s like 3G(HSPDA), PPPoE, dial…etc. And also we can expect WiMAX will be coming soon, so supporting WiMAX maybe important and necessary in the feature as well.

So far most network connections methods need to use PPP (Point-to-Point Protocol) to make connection, so we must try to focus on how’s PPP working and how to integrate PPP stuffs with our program. Fortunately, Most of operating system was using pppd to handle the ppp connections, it seems to be a standard we can consider. If we know how to get pppd immediate status, it will be easy to integrate PPP with our utility for us.

Regarding pppd implementation, it uses a tdb(samba database) to store current connection information(IP, interface, deivce, gateway, dns…etc) in system folder as root. Thus we need to read the file to get network status and the relationship between modem(eg, 3G modem, general modem) and network interface(eg, ppp0, ppp1…). Because of pppd is a user-space implementation as well as it doesn’t have library to provide serial APIs to let us be easy to operate its own stuffs, LXNM must direct open the tdb file. The problem is that pppd will update the tdb file anytime, it is possible that database be modified when LXNM is just reading the file. When it is happened, LXNM will get incorrect information or access failed to cause crazy crash. For solving this bug, we do some to check more information details which is from tdb. After some hard works, right now the issue was solved already.

Besides, the 3G support which is most important feature people concern. LXNM will try to use AT command to control 3G (HSDPA) modem to implement the connection handler, it can provide more information(ISP, Service Location, current area…etc) for your SIM Card with AT command. Some developers suggest us to research the implementation of Modem Manager Project for helping development.

Now we are working on this part which is that dialing with 3G modem, but there were also some weird problems we got. More details about those issues will be explained at blog next time. 🙂

LXNM current status and the plan in the future

Next generation of LXNM (Lightweight Network Manager) is still under development right now, You guys can see the prototype which was implemented in SVN already. In the future, LXNM will provide some programs includes lxnm daemon, utility which is a command line program to make control of all kind of networking devices be unified into only one utility, a LXPanel plugin and a standalone applet for running without LXPanel.

So the project will has three parts to be maintained:
1. lxnm (LXNM Daemon and command line utility – lxnetctl)
2. lxpanel-netstat (LXPanel plugin)
3. lxnm-applet (standalone applet)

For the current version in SVN, lxnm can be working now, we can using lxnetctl utility to connect to lxnm daemon to control our networking devices and get informations include ethernet and wireless interface.

BTW, I am now working on lxnm-applet to implement a graphical LXNM client to display and control network devices.

Besides, in the future, LXNM will provide a library to make easy to write a new LXNM client(eg, lxnm-applet) for developer.

Summer of Code slots available for LXDE through Debian

There are still opportunities for people interested in working on LXDE as a summer of code project. We are in touch for example with the Debian project, who offered to give spots to students from the LXDE project for example for a better integration. Also, new student projects are welcome. The summer of code program offers student stipends of 4500,- USD for studying and development work on specific free and open source projects.

Please check it out and apply as soon as possible. Also get in touch with us, so we can support your application.

The Debian program is at: and and on #debian-soc on

The application deadline is approaching soon. It is important to apply before 19:00 UTC April 3rd. Applications can still be adapted and specified with mentors after that date. You might regard your first application as a version 0.1 maybe. So, please, dont be shy. Good luck!

Summer of Code: Meet up with Leslie Hawthorn Community Manager of Google

Google LogoThe strength of an Open Source FOSS project comes from its community. Google has realized that and supports the community with its Summer of Code programme. I had the chance to meet up at an earlybird breakfast in Brussels with Leslie Hawthorn and some folks from Google like Peter Anvin to discuss some ideas of how we can work together to support the Asian FOSS community. Leslie Hawthorn is the program manager for Google’s Open Source Team and responsible for the Summer of Code project of Google.

I am happy that Google likes our ideas about bringing the international FOSS community closer together. The LXDE team is engaging in bringing the global FOSS community together by supporting the community with tools in their language, organizing meetings of contributors and educating folks about open source and free software. Recently some core members including Andrew Lee and me also joined the organization team of the OpenTechSummit series and we have much more in mind.

With me at the meeting I had also invited my friend Felix Fietkau aka nbd, the number one OpenWRT developer and member of the Freifunk community. The OpenWRT guys are currently working on making LXDE run with their speedy distribution. It is fascinating to see what will come out of it.

Google Summer of Code - LXDETalking about the GSoC: Leslie told me that Google is very positive of our upcoming application for the Summer of Code 2009. We will suggest some ideas for students who are interested to participate in our wiki soon. As this is a wiki, you are of course invited to post your ideas:
