Open DESIRE is a modeling/simulation language for dynamic systems and neural networks, a runtime compiler, and an experiment-protocol script for simulation studies. It supports up to 40,000 differential equations or neural networks, in scalar and/or vector form. It also supports very fast Monte Carlo studies and complex frequency-response plots.
The bitap library is a clean implementation of regular expression (regex/grep) string matching using the bitap algorithm. Approximate (a.k.a. fuzzy) matching is allowed. This is the same algorithm as the one used in Glimpse and agrep, but it is much more complete with regard to regular expression syntax, and is much cleaner.
Rx4RDF is a set of technologies designed to make W3C's RDF less complex and easier to use. It includes RxPath, which enables one to use familar XML technologies like XPath, XSLT, and XUpdate to query, transform and update an RDF model, Raccoon, an application server that uses an RDF model for its data store and RxPath to translate arbitrary requests to RDF resources, and ZML and RxML, alternative text formats for XML and RDF that were designed to allow novices to write XML and RDF with (nearly) the same ease as a Wiki entry.
esniff (formerly dbsniff) is a very basic set of tools useful for network traffic analysis and scripting across machines. It consists of three tools: esniff, nwait/npush, and loss_chk/loss_srv. esniff is a packet sniffer based on pcap that does certain things like traffic summaries (not better but hopefully easier than tcpdump). nwait and npush implement the DOS "pause" command working over the network. loss_chk and loss_srv are for checking the loss rate of a line.
fpwdman manages a file of passwords that is accessed by one master passphrase. It can import and export password files and makes it possible for encrypted password files to easily be transferred across operating systems. It supports multiple password files, which could be used when a number set of system administrators share a site-wide file of passwords for common tasks, while each maintaining a file of personal passwords. It also exports and imports password files to and from plain text and optionally uses user-generated random entropy. The source includes two command lines tools to encrypt and decrypt: ensbc and desbc.
Outwit is a suite of tools based on the Unix tool design principles allowing the processing of Windows application data with sophisticated data manipulation pipelines. The outwit tools offer access to the Windows clipboard, the registry, the event log, relational databases, document properties, shell links, and the event log.
galleryadd.pl is a script that recursively adds directories or images to a Gallery installation. Its features include a listing of the albums available in a Gallery, the creation of top-level albums with titles and descriptions, and support for the addition of images and directories to an existing album.
