以下是我翻譯的演講大綱。

node.js [1] 是個架在 Google V8 Javascript 引擎之上的事件驅動式的輸入輸出模組（evented
I/O）[2]。V8 是最快的 Javascript 虛擬機之一，node.js 用最佳的方法利用了 V8。

講者將會介紹 node.js 和實作 Comet 型態 [3] 的 chat 的實例。

[1] node.js:  http://nodejs.org/
[2] evented I/O: 用 event 和 callback 而不用 multi-thread 實作 server
的方式，twisted 是知名的一個這樣實作出來的 web server。
[3] comet: 一種讓 web server 可以把資料 push 到瀏覽器的做法，見

Hi,

I'm happy to invite Mr. Amir Salihefendic, the Lead Developer of
Plurk, to talk about an open source software that he has been playing
with, the evented I/O javascript package node.js. You definitely
should check it out if you like the idea of using the same language to
implement both the server side and client side programs. The talk will
start at 7:30 and end with Q&A around 8:30. You can stay to mingle
with the speaker and audiences until 10pm.

The following is an abstract of the talk provided by the speaker.

node.js is evented I/O built upon Google Chromes's V8 JavaScript
virtual machine. V8 is one of the fastest JavaScript virtual machines
ever built and node.js exposes V8 in the best ways.

There will be an introduction of node.js and an example of how to
implement a comet based chat.
