The authors show to identify, design, implement, test, and refactor use-case modules, as well as extend them. They also demonstrate how to design use-case modules with the Unified Modeling Language (UML)emphasizing enhancements made in UML 2.0and how to achieve use-case modularity using aspect technologies, notably AspectJ.
Key topics include
Making the case for use cases and aspects
Capturing and modeling concerns with use cases
Keeping concerns separate with use-case modules
Modeling use-cases slices and aspects using the newest extensions to the UML notation
Applying use cases and aspects in projects

Libnet is a generic networking API that provides access to several protocols. It is not designed as a all in one solution to networking. Currently many features that are common in some network protocols are not available with Libnet, such as streaming via TCP/IP. We feel that Libnet should not provide specific features that are possible in other protocols. If we restrict Libnet to the minimal needed to communicate (datagram/packets) then this allows it to support more interfaces. 很好的學習linux網絡變成的源碼
The Inter IC bus or I2C bus is a simple bidirectional two wire bus designed primarily for general control
and data transfer communication between ICs.
Some of the features of the I2C bus are:
• Two signal lines, a serial data line (SDA) and a serial clock line (SCL), and ground are required. A
12V supply line (500mA max.) for powering the peripherals often may be present.
• Each device connected to the bus is software addressable by a unique address and simple
master/ slave relationships exist at all times masters can operate as master-transmitters or as
master-receivers.
• The I2C bus is a true multi-master bus including collision detection and arbitration to prevent data
corruption if two or more masters simultaneously initiate data transfer systems.
• Serial, 8-bit oriented, bidirectional data transfers can be made at up to 100 KBit/s in the standard
mode or up to 400 KBit/s in the fast mode.
Written for embedded systems programmers and engineers, as well as
networking professionals, this in-depth guide provides an inside look at the
entire process of implementing and using the Linux TCP/IP stack in embedded
systems projects.
Jvm 規范說明。The Java Virtual Machine was designed to support the Java programming language. Some concepts and vocabulary from the Java language are thus necessary to understand the virtual machine. This chapter gives enough of an overview of Java to support the discussion of the Java Virtual Machine to follow. Its material has been condensed from The Java Language Specification, by James Gosling, Bill Joy, and Guy Steele. For a complete discussion of the Java language, or for details and examples of the material in this chapter, refer to that book. Readers familiar with that book may wish to skip this chapter. Readers familiar with Java, but not with The Java Language Specification, should at least skim this chapter for the terminology it introduces.
it has been designed to calculate the ergodic and outage capacity of a MIMO Rayleigh channel considering no CSIT and perfect CSIT
The channel is assumed to be spatially correlated according to a Kronecker
model but temporally uncorrelated.
ELinks is an advanced and well-established feature-rich text mode web (HTTP/FTP/..) browser. ELinks can render both frames and tables, is highly customizable and can be extended via Lua or Guile scripts. It is quite portable and runs on a variety of platforms. Check the about page for a more complete description.
ELinks is an Open Source project covered by the GNU General Public License. It originates from the Links project written by Mikulas Patocka.
If you want to see ELinks in action check out the screenshots.
