Peter J. Salzman was a computer hacker and former senior member of the hacking group, Legion of Doom, in the 1980s. He was the first hacker apprehended during Operation Sundevil and was caught while serving in the United States Air Force as a computer cryptography specialist.
Salzman was the founder and many time president of the Linux Users Group of Davis. He finished a Ph.D. at University of California at Davis in physics, doing a dissertation on the semi-classical theory of gravitation, a subtopic of quantum gravity. He is also the author and former maintainer of the popular guides Using GNU's GDB Debugger and Linux Kernel Module Programming Guide.
He co-authored (along with Norman Matloff) a popular book on computer program debugging called "The Art of Debugging with GDB", which was published on April 15, 2008.
Salzman finished a Master of Quantitative Finance at Baruch College. He worked as a quantitative developer for Fitch Ratings and Fitch Solutions before becoming a quantitative analyst for Algorithmics. He is currently[ clarification needed ] a quantitative analyst for IBM.

Computer programming is the process of performing a particular computation, usually by designing and building an executable computer program. Programming involves tasks such as analysis, generating algorithms, profiling algorithms' accuracy and resource consumption, and the implementation of algorithms. The source code of a program is written in one or more languages that are intelligible to programmers, rather than machine code, which is directly executed by the central processing unit. The purpose of programming is to find a sequence of instructions that will automate the performance of a task on a computer, often for solving a given problem. Proficient programming thus usually requires expertise in several different subjects, including knowledge of the application domain, specialized algorithms, and formal logic.
The GNU Debugger (GDB) is a portable debugger that runs on many Unix-like systems and works for many programming languages, including Ada, C, C++, Objective-C, Free Pascal, Fortran, Go, and partially others.
An integrated development environment (IDE) is a software application that provides comprehensive facilities to computer programmers for software development. An IDE normally consists of at least a source code editor, build automation tools and a debugger. Some IDEs, such as NetBeans and Eclipse, contain the necessary compiler, interpreter, or both; others, such as SharpDevelop and Lazarus, do not.
In computing, a core dump, memory dump, crash dump, storage dump, system dump, or ABEND dump consists of the recorded state of the working memory of a computer program at a specific time, generally when the program has crashed or otherwise terminated abnormally. In practice, other key pieces of program state are usually dumped at the same time, including the processor registers, which may include the program counter and stack pointer, memory management information, and other processor and operating system flags and information. A snapshot dump is a memory dump requested by the computer operator or by the running program, after which the program is able to continue. Core dumps are often used to assist in diagnosing and debugging errors in computer programs.
A debugger or debugging tool is a computer program used to test and debug other programs. The main use of a debugger is to run the target program under controlled conditions that permit the programmer to track its operations in progress and monitor changes in computer resources that may indicate malfunctioning code. Typical debugging facilities include the ability to run or halt the target program at specific points, display the contents of memory, CPU registers or storage devices, and modify memory or register contents in order to enter selected test data that might be a cause of faulty program execution.
Green Hills Software is a privately owned company that builds operating systems and programming tools for embedded systems. The firm was founded in 1982 by Dan O'Dowd and Carl Rosenberg. Its world headquarters are in Santa Barbara, California.
Fred Fish was a computer programmer notable for work on the GNU Debugger and his series of freeware Fish disks for the Amiga. He was a pioneering spirit pervasive in the Amiga community. The Fish Disks became the first national rallying point, a sort of early postal system. Fish would get his disks off around the world in time for regional and local user group meetings who in turn duplicated them for local consumption. Typically, only the cost of materials changed hands. The Fish Disk series ran from 1986 to 1994. In it, one can chart the growing sophistication of Amiga software and see the emergence of many software trends.
Open-source software development (OSSD) is the process by which open-source software, or similar software whose source code is publicly available, is developed by an open-source software project. These are software products available with its source code under an open-source license to study, change, and improve its design. Examples of some popular open-source software products are Mozilla Firefox, Google Chromium, Android, LibreOffice and the VLC media player.
KGDB is a debugger for the Linux kernel and the kernels of NetBSD and FreeBSD. It requires two machines that are connected via a serial connection. The serial connection may either be an RS-232 interface using a null modem cable, or via the UDP/IP networking protocol. The target machine runs the patched kernel and the other (host) machine runs gdb. The GDB remote protocol is used between the two machines.
Robert Samuel Fabry, as a student at the University of Chicago worked on COMIT II and MADBUG, an interactive debugger for MAD both on CTSS.
Norman Saul Matloff is an American professor of computer science at the University of California, Davis.
Intel oneAPI DPC++/C++ Compiler and Intel C++ Compiler Classic are Intel’s C, C++, SYCL, and Data Parallel C++ (DPC++) compilers for Intel processor-based systems, available for Windows, Linux, and macOS operating systems.
Intel Fortran Compiler, is a group of Fortran compilers from Intel for Windows, macOS, and Linux.
ptrace is a system call found in Unix and several Unix-like operating systems. By using ptrace one process can control another, enabling the controller to inspect and manipulate the internal state of its target. ptrace is used by debuggers and other code-analysis tools, mostly as aids to software development.
gdbserver is a computer program that makes it possible to remotely debug other programs. Running on the same system as the program to be debugged, it allows the GNU Debugger to connect from another system; that is, only the executable to be debugged needs to be resident on the target system ("target"), while the source code and a copy of the binary file to be debugged reside on the developer's local computer ("host"). The connection can be either TCP or a serial line.
Radare2 is a complete framework for reverse-engineering and analyzing binaries; composed of a set of small utilities that can be used together or independently from the command line. Built around a disassembler for computer software which generates assembly language source code from machine-executable code, it supports a variety of executable formats for different processor architectures and operating systems.
In computing, rr is a debugging tool for Linux designed to record and replay program execution. During the replay phase, rr provides an enhanced gdb debugging experience that supports reverse execution.
