C programming is a craft that takes years to perfect. A reasonably sharp person can learn the basics of
C quite quickly. But it takes much longer to master the nuances of the language and to write enough
programs, and enough different programs, to become an expert. In natural language terms, this is the
difference between being able to order a cup of coffee in Paris, and (on the Metro) being able to tell anative Parisienne where to get off. This book is an Advanced text on the ANSI C programming
language. It is intended for people who are already writing C programs, and who want to quickly pick
up some of the insights and techniques of experts.
The TJA1040 is an Advanced high speed CAN transceiver for use in
automotive and general industrial applications. It supports the differential
bus signal representation described in the international standard for
in-vehicle high speed CAN applications (ISO11898). CAN (Controller Area
Network) is the standard protocol for serial in-vehicle bus communication,
particularly for Engine Management and Body Multiplexing.
The TJA1040 provides a Standby mode, as known from its functional
predecessors PCA82C250 and PCA82C251, but with significantly
reduced power consumption. Besides the excellent low-power behavior
the TJA1040 offers several valuable system improvements. Highlights are
the absolute passive bus behavior if the device is unpowered as well as
the excellent EMC performance.

SharpPcap tutorial: a step by step guide to using SharpPcap
The text of this tutorial is taken directly from WinPcap's official tutorial but is modified to show the C# use of the SharpPcap library. All examples can be downloaded together with SharpPcap source code from SharpPcap 's homepage. The WinPcap library must be installed before attempting to run any of these examples, so please download and install the latest version from WinPcap's download page.
SharpPcap was written and tested using .NET v1.1 and Windows 2000/XP. I have no idea about other .NET and Windows versions. If you do try it, please report your results.
The following topics are covered in this tutorial:
Obtaining the device list
Obtaining Advanced information about installed devices
Opening an adapter and capturing packets
Capturing packets without the event handler
Filtering the traffic
Interpreting the packets
Handling offline dump files
Sending Packets
Gathering Statistics on the network traffic

In the hit CBS crime show Person of Interest, which debuted in 2011,
the two heroes—one a former Central Intelligence Agency agent and
the other a billionaire technology genius—work together using the
ubiquitous surveillance system in New York City to try to stop violent
crime. It’s referred to by some as a science fiction cop show. But the
use of Advanced technology for crime analysis in almost every major
police department in the United States may surpass what’s depicted
on TV crime dramas such as Person of Interest. Real-time crime cen-
ters (RTCCs) are a vital aspect of intelligent policing. Crime analysis
is no longer the stuff of science fiction. It’s real.
We review the current applications of photonic technologies to Smart Cities. Inspired
by the future needs of Smart Cities, we then propose potential applications of Advanced
photonic technologies. We find that photonics already has a major impact on Smart
Cities, in terms of smart lighting, sensing, and communication technologies. We further
find that Advanced photonic technologies could lead to vastly improved infrastructure,
such as smart water‐supply systems. We conclude by proposing directions for future
research that will have the greatest impact on realizing Smart City initiatives.
Duringthe past years, there has been a quickly rising interest in radio access technologies for providing
mobile as well as nomadic and fixed services for voice, video, and data. This proves that the difference
in design, implementation, and use between telecom and datacom technologies is also becoming more
blurred. What used to be a mobile phone used for voice communication is today increasingly
becoming the main data communication device for end-users, providing web browsing, social
networking, and many other services.
