NetworkManager in Fedora 13



NOTE:
The template shouldn't be Marketing. To be changed before release.

NetworkManager

NetworkManager aims to provide a "pain free networking" experience for Linux users. Fedora 13 ships with a stabilized snapshot of NetworkManager 0.8.1 which includes extended functionality; for example DHCPv6, Bluetooth DUN and Mobile Broadband Status.
NetworkManager's upstream project maintainer since 2005, Dan Williams provided the community a very in-depth post about NetworkManager 0.8, identifying it as "the taste of a new generation", which can be consulted here.

From a very objective approach, Fedora 13 is the result of a community effort and many times "The Cathedral and the Bazaar" (link) is pointed as a reference to better understand it's "modus operandi". NetworkManager, despite being started by Red Hat, also has a great effort from the community, and following this line, on behalf of Fedora's Marketing Team, I've interviewed Dan Williams regarding some aspects of the NetworkManager development.

Interview with Dan Williams

Dan Williams is a Senior Software Engineer in the Red Hat Desktop, being involved since 2003 with OpenOffice.org and became upstream project maintainer for NetworkManager in 2005. He was heavily involved in OLPC (2005-2007) helping planning and implementing core features of Sugar and OLPC Wireless.
Dan characterizes his involvement with Fedora and FOSS Communities as an advocate for users by attending kernel wifi summits and being involved on Linux wireless mailing lists.

"It's been a great ride over the last 7 years." - Dan Williams

Given the nature of FOSS contributions, sometimes natural barriers arise to new potential developers, according to Dan, one of the most relevant is the lack of upstream guidance. Sometimes a potential developer shows up, often upstream developers don't have much time available to help nurture new developers through some of the initial stages. Dan's points that documentation has a very important role here, as new potential developers can be forwarded avoiding the to repeat the effort every time when new developers join.
NetworkManager provides a good grounds for developers seeking knowledge and experience in the fields of:

• D-Bus;
• GObject;
• PolicyKit;
• Networking System Interaction;
• 3G Modems;
• netlink API's;
• etc;

As an advice for potential developers willing to join NetworkManager:

"Keep asking questions; no question is too stupid or embarrassing to ask. Then, when you understand the solution to your question, tell us how to improve the documentation so other people benefit too. Since we've been involved in the project for a long time, we don't always know what the initial roadblocks are to building the source, understanding the architecture, etc."

Dan also points the feedback from users to the success of NetworkManager. Even non-developers have a key role in the development of NetworkManager, providing good bug reports. A comprehensive article is available here.

"The #1 and #2 items missing from many bug reports is what package version of NM you've experienced the bug with, and what hardware you're using. As the Fedora project, we should work harder to automate the collection of this information like Ubuntu has done with Launchpad. This stuff should really be automatic, but for now we'll need users to do it for us." - Dan Williams

When inquired about the distribution/tools used for the development of NetworkManager:

"I develop mainly on Fedora, though occasionally I do a build on Ubuntu when I need to dig into a problem there and the Ubuntu team hasn't been able to debug it further.

I use gnome-terminal with multiple tabs for workflow (usually have NetowrkManager's directory open in one tab, ModemManager's in another, and network-manager-applet's in a third), and GEdit for actual coding. No, I don't use emacs or vi, mainly because I started coding on Mac OS long ago and all the tools there are GUI development environments. GEdit does 95% of what most people really need from an editor, and I've never been a fan modal editors like emacs/vi probably because I used something else first." - Dan Williams
