Alma is a software workshop for modeling and analyzing. It reads several sources (languages, models, etc.), helps you design for object-oriented modeling (definition of classes, relations, patterns, etc.), modifies the structure and the code, and outputs new sources, documentation, diagrams, etc. It is designed for object-oriented modeling (definition of classes and relations) and for migrating code in older languages. It meets two needs, offering a simplified software modeling workshop for small projects and making it easier to do rewrites, ports, and encapsulation of non-OO code.
Ciao is a complete Prolog system subsuming ISO-Prolog with a novel modular design which allows both restricting and extending the language. Ciao extensions currently include feature terms (records), higher-order, functions, constraints, objects, persistent predicates, a good base for distributed execution (agents), and concurrency. Libraries also support WWW programming, sockets, and external interfaces (C, Java, TCL/Tk, relational databases, etc.). An Emacs-based environment, a stand-alone compiler, and a toplevel shell are also provided.
Dynamic Probes (Dprobes) is a generic and pervasive system debugging facility that will operate under the most extreme software conditions such as debugging a deep-rooted operating system problem in a live environment. Dprobes allows the insertion of fully automated breakpoints or probepoints anywhere in the system and user space. Each probepoint has an associated set of probe instructions that are interpreted when the probe fires. These instructions allow memory and CPU registers to be examined and altered using conditional logic. When the probe command terminates, prior to returning to the probed code, a syslog record may be optionally generated.
GNATS is a portable incident/bug report/help request-tracking system which runs on UNIX-like operating systems. It easily handles thousands of problem reports, has been in wide use since the early 90s, and can do most of its operations over e-mail. Several front end interfaces exist, including command line, emacs, and Tcl/Tk interfaces. There are also a number of Web (CGI) interfaces written in scripting languages like Perl and Python.
Hammerhead is a stress testing tool for Web sites. It initiates connections from multiple IP aliases and simulates a user from each alias. It is fully configurable, and there are numerous other options for creating problems with a site. Extensive data collection is also available.
PHPXref is a Perl script that cross-references classes, functions, variables, and SQL tables used in a PHP-based Web site and generates simple HTML output designed to make browsing through code easy. In addition, it can extract phpdoc style comments from the PHP files to provide browsable documentation.
