We just held a technical salon today named "template<language L> Inside the L Object Model". When I was looking at some code of Ruby, I found the object model is very different to a static language like C++. So I suggested the idea of discussing various object model of different languages. Finally, our amazing MSTC staffs made it happen in the form of a salon.

We finally selected 5 languages and invited 5 people to talk about their object model:

• C++: shifan, the board manager of C++ board of freecity BBS. An interesting person, know C++ very well, commonly known as "模教教主". :)
• Java: gbb, the board manager of Programming Technique board of cc98 forum. A very enthusiastic person. WARNING: he might become extremely exciting when discussing about any technical topic. :p
• Lisp: binghe, the board manager of Computer Language board of freecity BBS. THE Lisp hacker of our school. He always think Lisp (especially Common Lisp) is the ultimate super cool and powerful language ever exists. :)
• Python: Mike, the board manager of Linux board of cc98 forum. Still a freshman but already has a very good knowledge of Linux, Open Source and programming. Bright future! :)
• Ruby: me. I'm also board manager of cc98 forum and freecity BBS. :p I'm interested in various languages.

We gave about 20 minutes to each speaker to introduce the object model. The remained time is for discussing. The salon is held in the office of MSTC. We have many people there.

Unfortunately, we didn't have enough seats for all the people.

To avoid religion war, we selecte the alphabetic order of the languages. shifan introduced C++ object model first:

Then gbb talked about the Java object model:

Next is the Lisp geek binghe who introduced CLOS to us:

After that, Mike talked about the Python's way of OOP:

And finally, it's my turn to talk about Ruby:

Then comes a short summery of our enthusiastic host windreamer:

And the final free discussing time:

Here are the slides of each talk:

• C++ slides
• Java slides
• Lisp slides
• Python slides and related codes
• Ruby slides

Our office is on Yuquan Campus, we have return to Zijingang Campus afterwards. Most people returned to Zijingang before the discussing finished, But it's too late when we finished the discussing. We (Mike and I) found the time for the last bus had just passed, and we didn't take enought money with us for a taxi. But finally we are lucky to found a late bus. :D

Finally, thanks everyone for attending this salon. And special thanks to those speakers who devote their time to prepare for the great talks!
