gdb stands for GNU debugger. gdb is a part of GNU toolchain which has other tools like gmake, gcc etc. gdb helps tack down the source of bugs by tracing program execution. Debugging basically means you load your program under a debugger, set breakpoints, run your program, examine data at breakpoints and step through the program while its executing to track down bugs. The program being debugged can be written in Ada, C, C++, Objective-C, Pascal (and many other languages). Those programs might be executing on the same machine as GDB (native) or on another machine (remote). GDB can run on most popular UNIX and Microsoft Windows variants (windbg). gdb supports C and C++ debugging. gdb supports many processors. gdb is not an IDE for browsing code. There is a GUI version of gdb called KDbg. All Unix and Linux distros come loaded with GNU toolchain of which gdb is a part. This article is about the basic gdb execution control commands, inspecting data, debugging threads and processes etc. If you have any question/doubts please post them in the comments section.

Expect is a Unix automation and testing tool written by Don Libes. It was written as an extension to Tcl scripting language for interactive application such as telnet, ftp, ssh, passwd, rlogin, fsck etc. It uses Unix pseudo terminals to wrap up subprocesses transparently, allowing the automation of arbitrary applications that are accessed over a terminal. With Tk, interactive applications can be wrapped in X11 GUIs. Expect scripts provide old tools with new power and flexibility. Well, that was Expect script as described in Wikipedia. In other words, Expect can be of great help to system administrators and developers by automating certain monotonous tasks, which have to be done very frequently. Administrators can automate tasks such as read from a file a set of ip addresses and then log into each of them and run some commands. You can have Bash shell script to read each ip address from the file and then call Expect script to login to each system and perform certain routine task. Developers can build executables on host and automatically copy them to a particular location on the target system. Expect can make your life a lot simpler. It can be a real life saver at times. Perl and Python have their own version of Expect.

User Access Control (UAC) is a technology and security infrastructure deployed in Microsoft Windows Server 2008 and Windows Vista. It improves the security of Microsoft Windows systems and allow application software trusted by the user (with sufficient administrative priviledges) to run. In this way, malware is kept out from compromising the system. In other words, a user account may have administrator privileges assigned to it, but applications that the user runs do not inherit those privileges unless they are approved beforehand or the user explicitly authorizes it. In this post, you will learn how to enable and disable User Access Control (UAC) in Windows Server 2008 aslo known as Longhorn. The method is same for Windows Vista as well.
