CollectionSpy is a Java profiler that focuses on tracking and analyzing your program's usage of Collection Framework containers. It detects hashing container (e.g. HashMap) corruption due to mutating keys. It tracks expensive internal rehashing of containers whose capacity needs expanding. It detects multithreaded access to any unsynchronized container (e.g. HashMap, ArrayList). It visualizes hashing container bucket list lengths, allowing you to diagnose worst-case access performance.
Galemu is an emulator tool for Generic Array Logic (GAL) and Programmable Array Logic (PAL) chips. It provides a trivial command line tool and an advanced QT4-based graphical user interface. JEDEC fuse maps are supported for configuring the emulated chip. Combinatorial and registered chip configurations are supported.
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.

Accerciser lets you test all aspects of accessibility on the GNOME desktop. It uses AT-SPI to inspect and control widgets, allowing you to check whether an application is providing correct information to assistive technologies and automated test frameworks. It has a simple plugin framework that you can use to extend and customize the accessibility information displayed. It is written in Python and uses the pyLinAcc component from LSR to interact with AT-SPI using pyORBit. In essence, it is a next generation at-poke tool.
