lida is a fast feature packed interactive ELF disassembler / code-/cryptoanalyzer based on bastards libdisasm (see bastard project).
ptkdb is a debugger for perl using a Perl Tk GUI as its interface.
Performs basic checks on shell scripts for the presence of non portable syntax.
It is a Process Monitoring Toolkit with the ability of Extend. E.g. You can use it to monitor a specified process. And set a triger like (over 50MB mem use) then do something like (report to DB).
Parsing, interpreting, checking and profiling C application (ISO/IEC 9899:1999 (E))
The NT POSIX C Runtime Library is an IEEE standard runtime library for the NT POSIX subsystem. It can be used as a complete replacement or a side by side alternative for what is shipped with the Interix SDK.
NEmu is an emulator/simulator for exploring computer architecture. It provides a virtual machine, a debugger, and simulations of various cpus and hardware. NEmu is built on top of ALib, my own application framework.
A Curses-based Perl debugger with most of the essential functions such as monitoring windows for paddlist, call stack, custom watch expressions, etc. Suitable for debugging or tracing complicated Perl applications on the spot.
Monitor contexts and context relations in complex SW stacks
SpurTracer is a push-notification based monitoring solution for heterogenous loosely coupled IT infrastructures. It complements a service-endpoint monitoring solution like Nagios with a component-level interface auto-discovery. It automatically provides a certain level of functional tracing along with many non-functional measurements (e.g. call, error and timeout rates, interface latency, component execution...). While being zero config itself, SpurTracer relies on you adding push notification support to the components you want to monitor. The best way to use SpurTracer is by adding punctual tracing to components in your infrastructure on-demand.
Trackalloc is a lightweight, very compatible heap profiler for C programs that lets a developer quickly and visually assess trends in a program's memory usage.
spyGLass is an OpenGL call tracer and debugger. It goes a step further than simply using ltrace because it knows what the arguments to the various gl* calls are, and it also knows about OpenGL's error flag.
