It's well known that we had the biggest Solaris/OpenSolaris user group meeting in Beijing on 10.15. A total of 248 developers attended this meeting. Sin-Yaw Wang, our VP and General Manager of China ERI, gave a keynote speach on OpenSolaris opportunites for developers in China, and Sun's strategy on OpenSolaris. Erik Nordmark, our Distinguished Engineer on Solaris Networking, delivered a lecture on Solaris Networking.

On 10.29 we had another big gathering of Solaris/OpenSolaris developers
at the graduate school of China Academia of Science. A total of 178
developers attended this meeting, and 178 surveys were collected from
the audience. Most of the audience received a T-Shirt or a set of DVD's
(Solaris Express DVD + OpenSolaris Source Code & Compiler DVD) as a gift.

Vincent Liu (Technical Consultant, MDE) gave a speech and live demo on
DTrace. The audience has raised many questions related to Dtrace, some memorable ones like:

1. The dtrace action print() will use the tty driver. If there are something broken in that driver, does it mean that all printings are rubbish?

2. What's the purpose of print out all the callstack in the Solaris 

3. Performance impact of dtrace

4. What changes need to be made in order to port DTrace to FreeBSD/Linux?

5. what's the test methodology of dtrace. (how to prove dtrace result is right?) I'm not sure about this one, can you help to find the answer?

I gave a speech and a live demo on the installation of Solaris Express, compiling the OpenSolaris kernel with Sun Studio and ON build tools, and Cap-Eye-Installing a customized kernel and BFU to upgrade an existing OpenSolaris OS. Also, I have got some challenging questions like:

1. How could I make configure before the build?

2. Is it possible to cross build OpenSolaris on GNU/Linux?

3. Performance test for the OpenSolaris

4. The requirements for Solaris install

5. How does solaris visit the file systems under other systems

6. Can Cap-Eye-Install and BFU be used in production systems? What's the difference between them? How to fall back to the original version?

The presentation materials were uploaded to SDN China portal and opensolaris.org/os/community/os_user_groups/bjosug/">Bejing User Groupto be shared with a broader audience.

Many engineers from the Beijing OpenSolaris User Group (mainly from the OPG group) contributed in various ways to this meeting. We have Oliver, Cathy, Vitor, Si-yuan to help answer some questions. 

The next meeting will take place on 11.12. Many developers not in Beijing are asking whether we can deliver the same content to other cities. We will distribute the DVDs of the user group on the web and hopefully this will help somewhat.

Any suggestions or comments are highly appreciated!
