First of all, the Applet-phone is a SIP User-Agent
with audio and text messaging capabilities. But i s also embedded in
an applet where you can use it as usual if your firewall allow you to
use the UDP transport. If not, you can use TCP to carry your voice in a
voice messaging fashion. Your voice is recorded and encoded locally
then sent as a message, decoded and played back by your peer. Voice
messaging allow you to go through any firewall, so that you can
continue to chat and talk with your friends from an applet !

Over the last few years, Linux has grown both as an operating system and a tool for personal and business use. Simultaneously becoming more user friendly and more powerful as a back-end system, Linux has achieved new plateaus: the newer filesystems have solidified, new commands and tools have appeared and become standard, and the desktop--including new desktop environments--have proved to be viable, stable, and readily accessible to even those who don t consider themselves computer gurus.
C++, although a marvelous language, isn t perfect. Matthew Wilson has been working with it for over a decade, and during that time he has found inherent limitations that require skillful workarounds. In this book, he doesn t just tell you what s wrong with C++, but offers practical techniques and tools for writing code that s more robust, flexible, efficient, and maintainable. He shows you how to tame C++ s complexity, cut through its vast array of paradigms, take back control over your code--and get far better results
Using the UnderC Tokenizer Class
It s often necessary to parse complex text files, where standard i/o
is too clumsy. C programmers fall back on strtok(), but this can be
tricky to use properly. Besides, you are still responsible for keeping
strtok() fed with new input, and I don t like the schlepp.
Tokenizer is a text-parsing input stream, modelled after the (undocumented)
VCL TParser class, and based on the UnderC tokenizing preprocessor front-end.
《JavaServer Faces》
In JavaServer Faces, developers learn how to use the new JavaServer Faces framework to build real-world web applications. The book contains everything you ll need: how to construct the HTML on the front end how to create the user interface components that connect the front end to your business objects how to write a back-end that s JSF-friendly and how to create the deployment descriptors that tie everything together. This book is a complete guide to the crucial new JSF technology.

Parking Lot Simulation：
Parking lot attendants often park cars bumper-to-bumper, several cars deep. This maximizes the number of cars they can fit into a parking lot at the expense of complicating the process of retrieving someone s car when they want to leave. Consider the case of a person wanting to leave the parking lot but their car is parked in the back of a row of cars. In this case, all the cars parked in front of this person s car must be temporarily moved to allow this person to leave.
SDP, Service Delivery Platform, is more for telecom operators who want to manage the Data Service better delivered to the end device users by bridging with back-end content providers. Operators rely on the content provider to create & distribute data content to different types of devices. This is different from the open world in the internet communication. Operators must control who can access what content based on his rate plans. Also, based the content access results, the process will be recorded as the transaction records based on which billing statements can be generated to collected the money and shared by operators and content providers. I am working on the conceptual architecture level and the real implementation is very complicated due to too many types of service from different content providers to different types of devices based on the different types of the rate plans.
