ngrep strives to provide most of GNU grep's common features, applying them to the network layer. ngrep is a pcap-aware tool that will allow you to specify extended regular or hexadecimal expressions to match against data payloads of packets. It currently recognizes IPv4/6, TCP, UDP, ICMPv4/6, IGMP and Raw across Ethernet, PPP, SLIP, FDDI, Token Ring, and null interfaces, and understands BPF filter logic in the same fashion as more common packet sniffing tools, such as tcpdump and snoop.
RJCE enables the editing of any method at runtime, applying the changes to any combination of objects, such as an array, or a complete class. It consists of a compiler, javaprec, and an IDE, Runtime Object Modifier (ROM). javaprec is used to compile programs, enabling runtime editing, and uses both sun.tools.javac and ANLTR for compilation. ROM is a JFrame used for editing methods, browsing classes, and viewing variables at runtime. It also includes an interpreter that runs Java scripts (which circumvent normal language access control) and is run from within any Java program. Aspects are also incorporated into RJCE, to enhance runtime editing.
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.
MPI Parallel Environment (MPE) is a software package for MPI (Message Passing Interface) programmers. It provides users with a number of useful tools for their MPI programs such as a set of profiling libraries that collect information about the behavior of MPI programs, graphical trace file analyzers, serializers, type checkers, collective operations validators, etc.
TclDTrace is a binding of libdtrace to the Tcl programming language. DTrace is a system profiling suite created by Sun Microsystems. It allows the user to profile a program without modifying its text, or even without the need to distract it if it is running. It consists of a set of library hooks called "providers", a set of tools, a C API (libdtrace), and its own specially crafted scripting language called D. A Tcl binding to libdtrace will allow users to run D scripts and process their results directly from Tcl.
