Pin is an ATOM-like instrumentation tool for Linux executables. It allows arbitrary code (written in C or C++) to be injected at arbitrary places in an executable. Unlike Atom, Pin does not perform the instrumentation statically by rewriting the executable, but rather dynamically by adding instrumentation while the executable is running. Currently supported platforms include IA-32, Intel Xscale, and Itanium processors.
rtprof is a profiling tool that uses GCC's function instrumentation mechanism to provide an OpenGL-based call graph visualization representing the process being profiled. Visualizations are displayed in real-time in parallel with the running process and can be interactively examined using mouse and keyboard control.
Cougaar Memory Profiler is a tool for debugging memory usage and leaks in Java applications. It features a scalable 100% Java design that is lighter weight than existing JVMPI-based Java profiling tools (hprof, OptimizeIt, JProbe, etc), making it ideal for large-scale application memory profiling. The profiler uses automated BCEL-based bytecode modification, tables of WeakReferences, and servlet-based UIs.
Nonpareil is a microcode-level simulator for HP calculators introduced between 1972 and 1982, including the HP-35, HP-45, HP-55, HP-25, HP-34C, HP-38C, HP-41CV, HP-11C, HP-12C, HP-15C, HP-16C, and other models. The necessary microcode is included, as is a microcode assembler. The GTK+ toolkit is used for the user interface.
The Guarded Memory Move tool is useful for studying buffer overflows and catching them together with a "good" stack image. It uses dynamic function call interception to catch the most common functions that are used by attackers to exploit stack buffers. It uses the LD_PRELOAD capability, and, on discovering an exploit, will produce a core dump with the necessary information to debug the exploit and fix the software.
Roadsend PHP produces optimized stand alone applications, libraries, and Web applications from standard PHP source code. The compiler produces native machine code, not PHP byte code, so no interpreter is required. It is a new implementation of the PHP language and runtime environment compatible with Zend PHP. It does not share any code with the original PHP implementation.
U++ is a C++ cross-platform rapid application development suite focused on programmers' productivity without sacrificing runtime performance. Based on strictly deterministic design, it provides a viable alternative to garbage-collected platforms, even for business logic oriented problems.
