GNU grep is based on a fast lazy-state deterministic matcher (about twice as fast as stock Unix egrep) hybridized with a Boyer-Moore-Gosper search for a fixed string that eliminates impossible text from being considered by the full regexp matcher without necessarily having to look at every character. The result is typically many times faster than Unix grep or egrep.
dlh is a fast LaTeX-to-HTML translator written in C that can handle most of LaTeX. It features not invoking LaTeX for any purpose; with the exception of figure support it's completely independent of any other program. In particular, it generates all cross-references and table of contents in a single run Tables are supported and translated into HTML3 tables, and PostScript figures (\psfig command) are supported (requires GhostScript and pnmtogif to translate PS into GIF files).
The Directory Server NT Authentication Module project is made of two parts: The first is a simple daemon which takes an NT user's domain credentials (including password) and attempts to authenticate via the SMB protocol with those credentials. The second part is a plugin which takes an LDAP DN and password and discovers the DN's NT domain identifier (if the entry has such an ID). The daemon will only listen on localhost, so the credentials are not exposed via the network, and it does not run as root, so that compromise can be limited. It attempts to locate all the domain controllers for an arbitrary domain, so failure of one DC does not cause the module to fail the authentication attempt unless no DC can be found that will accept the credential.
Ch is an embeddable C/C++ interpreter for cross-platform scripting, shell programming, 2D/3D plotting, numerical computing, and embedded scripting. It is the simplest solution to numerical computing and visualization in the domain of C/C++. It supports the ISO 1990 C Standard (C90), major features in C99 (complex numbers, variable length arrays or VLAs, type generic functions, long long data type, etc), classes in C++, and extensions to the C language like nested functions, string types, etc. It can be embedded in other applications and hardware and used as a scripting language. C/C++ code is interpreted directly with no compilation to intermediate code. It supports Linux, Windows, MacOS X, Solaris, HP-UX, and FreeBSD.
Turbo Seek provides the capability to create and run a directory and search engine with ease. It comes with a visually friendly admin control panel that provides all of the aspects to create, customize, and run a fully functional search engine. It supports unlimited sub-categories, and includes a crawler, link checker, site rankings, site reviews, the ability to customize all text/layouts, relevance to search keywords, and more.
Secure FTP API for Java is a collection of classes that allows you to add secure file transfer capabilities to your Java applications. It has a complete implementation of the File Transfer Protocol as defined RFC 959, and support for secure file transfer using SSL/TLS as defined in RFC 2228. Both explicit and implicit SSL connections are supported. It has an extendable architecture to support legacy/non-standard FTP servers, event notification to notify the connection and transfer events to interested objects, support for active and passive data transfers, support for ASCII and binary data types, and the ability to set the timeouts and buffer size to use for the control and data connections.
