What: We are developing a tool to track variables and their values in C programs as they change at runtime. Because of the low-level, unrestricted memory access the language allows, the challenge lies in collecting accurate information without disrupting the program’s execution. Our approach combines techniques from profiling with memory tracking to analyze dynamic allocation throughout the lifetime of a program.

In 1991, a group of Sun Microsystems engineers led by James Gosling decided to develop a language for consumer devices (cable boxes, etc.). They wanted the language to be small and use efficient code since these devices do not have powerful CPUs. They also wanted the language to be hardware independent since different manufacturers would use different CPUs. The project was code-named Green.

Note: The Yellow LED will flash when the unit is transmitting data from the computer to the controller. The Green LED will flash when the unit is receiving data from the computer to the controller. There is no power on LED indicator. Look in your Device Manager to see if the USB485 card shows up under one of the COM Ports. This is a clear indication that the unit is in good condition and is ready to communicate.

TCP/IP Internetworking With gawk

This chapter provides a (necessarily) brief introduction to computer networking concepts. For many applications of gawk to TCP/IP networking, we hope that this is enough. For more advanced tasks, you will need deeper background, and it may be necessary to switch to lower-level programming in C or C++.

There are two real-life models for the way computers send messages to each other over a network. While the analogies are not perfect, they are close enough to convey the major concepts. These two models are the phone system (reliable byte-stream communications), and the postal system (best-effort datagrams).

Sharing personal content online is surprisingly hard despite the recent emergence of a huge number of content sharing systems and sites. These systems suffer from several drawbacks: they each have a different way of providing access control which cannot be used with other systems; moving to a new system is a lengthy process and requires registration and invitation of all one’s friends to the new system; and the rules for access control are complicated and become more so as our networks of online friends grow.

Online Backup Quick Guide

Whether at home and in the office, each day we save an increasing amount of data (documents, worksheets, contracts, pictures, drawings, projects, videos, music, etc.). Protecting this data is essential but, at times, we only realize this when it’s too late. Today, traditional backup devices (DVD, external HD, USB keys, floppy disks, etc.) have become obsolete since unreliable, costly and inconvenient. A new service is now on the market that promises to revolutionize how we protect and organize our files: Online Backup. The purpose of this guide is to help you select the Online Backup service that best meets your business or home needs.

This section provides a general overview of DVD technology. Topics covered include a brief history, a comparison of DVDs with compact disc (CD) technology, the different types of DVD that are currently available, and a glimpse at the future of DVDs.

History
DVDs were first developed in 1995 through a consortium of ten companies: Hitachi, JVC, Matsushita, Mitsubishi, Philips, Pioneer, Sony, Thomson, Time Warner, and Toshiba. These companies formed the DVD Consortium, which in April 1997 became the DVD Forum. The mission of the forum is to promote the worldwide acceptance of DVD products across the entertainment, consumer electronics and IT industries. In early 2000, membership in the DVD Forum reached some 230 companies and organizations that are engaged in DVD research, development and/or manufacturing. Although DVD once stood for “Digital Video Disc” or “Digital Versatile Disc,” DVD now simply stands for DVD.
