What is the web service language/framework Barbara Liskov mentioned

In her talk titled "The Power Of Abstraction" given in OOPSLA2009, Barbara Liskov mentioned that she started to learn web services programming, and the language or framework she used has many global variables. I really wonder what she was using.

The talk is good and especially reveals the history of development of abstract data type by the list of influential papers.

Zero copy for Java HTTP file server

This makes it impossible for normal Java-based HTTP service to take the advantage of zero copy.

in reference to:

"It is not possible to create a channel for an arbitrary, pre-existing socket, nor is it possible to specify the SocketImpl object to be used by a socket associated with a socket channel."
- SocketChannel (Java 2 Platform SE 5.0) (view on Google Sidewiki)

Free DNS servers

Maybe some ISP's like this. The last time I tried to find a free DNS is two years ago when the ISP DNS was down. I like the ip they choose, easy to remember.

Maybe DNS is the first place that browsing statistic can be collected.

in reference to:

"To try it out: Configure your network settings to use the IP addresses and as your DNS servers or Read our configuration instructions."
