NoBug is a library which provides assertions, logging statements, and annotations for C and C++ programs. It includes pre-/post-condition and invariant checks, as well as generic assertions. Checks are enabled based on build-levels and scope tags. It also includes debugger support (valgrind), dumping of data structures, logging your application's activities, runtime customizable logging via environment variables, different logging targets (ringbuffer, stderr, syslog, debugger, etc.), and annotation of your source code regarding known bugs, things to do, and planned things. It can track resources and detect deadlocks.
Xdump is a little PHP library which can provide full featured variable dumps. It requires the ability to show the source code around the line where the dump was invoked. It features contractible HTML+JS dumps. It shows nicely backtraces, including source code lines for every step. Reference checking is used to avoid recursion. It is object oriented and extendible.
Elvyx is a tool designed to monitor and profile JDBC activity. This JDBC profiler has a wrapper that intercepts access to the database and sends this information to the elvyx server. The server receives the information, stores the data into a database, and serves this information to the client. The client shows SQL statements, bound SQL statements, elapsed time, elapsed time preparing the statements, and more.
The Perl Dev Kit (PDK) provides essential tools for building and deploying Perl applications. PDK features cross-platform wrapping and application builders for various operating systems, plus a suite of tools to speed development time and improve code quality and consistency across teams.
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.
radare2 aims to create a complete, portable, multi-architecture, Unix-like toolchain for reverse engineering. It is composed of a hexadecimal editor (radare) with a wrapped I/O layer supporting multiple backends for local/remote files, debugger (OS X, BSD, Linux, W32), stream analyzer, assembler/disassembler (rasm) for x86, ARM, PPC, m68k, Java, MSIL, and SPARC, code analysis modules, and scripting facilities. It also has a bindiffer named radiff, base converter (rax), a shellcode development helper (rasc), a binary information extractor supporting PE, Mach0, ELF, class, etc. named rabin, and a block-based hash utility called rahash. Radare was rewritten as radare2, and the old version is only maintained for bugfixes.
