nss_ldap is an RFC 2307-compliant set of C library extensions which allows X.500 and LDAP directory servers to be used as a primary source of aliases, ethers, groups, hosts, networks, protocol, users, RPCs, services and shadow passwords (instead of or in addition to using flat files or NIS).
Linux NTFS provides Linux kernel drivers, a multiplatform NTFS library, and tools to create, resize, clone, rescue, query, label and fix NTFS volumes, and to undelete, resize, list, and query files for the filesystem used by Windows XP, 2003, 2000, NT4, and Vista. It also provides support for the Logical Disk Manager (LDM) that controls Windows' Dynamic Disks and is used to create software mirrors, stripes, and RAID.
NTLogon is a Python script that generates Samba/NT-logon scripts from an easy-to-modify configuration file. It currently understands the Samba macros for User, Group, and Architecture. The configuration file looks like a cross between an INI file and a DOS batchfile, so most Windows users will feel somewhat comfortable.
ntopmg is a network probe that shows network usage in a way similar to what top does for processes. It acts as a Web server, creating an HTML dump of the network status. It sports a flow collector, an HTTP-based client interface for creating ntop-centric monitoring applications, and RRD for persistently storing traffic statistics. Its C++ core can be scripted in Lua, for changing the appearance and extending functionality.
nut is nutrition software to record what you eat and analyze your meals for nutrient composition. The database included is the latest USDA Nutrient Database for Standard Reference. This database contains values for vitamins, minerals, fats, calories, protein, carbohydrates, fiber, etc., and includes the essential polyunsaturated fats, Omega-3 and Omega-6. Nutrient levels are expressed as a percentage of the Daily Value, the familiar standard of food labeling in the United States, but also can be fully customized. Foods can be added from recipes or food labels, and nutrient intake can be graphed. The program is completely menu-driven and there are no commands to learn.
nwfiir and its accompanying software wfird allow design and use of a HiFi quality digital equalizer based on a WFIR filter (Warped Finite Impulse Response). It can take advantage of multiple processors, e.g. on a dual Pentium II 300 MHz it manages to run a two-channel equaliser with 275 taps, with 16 bit 44.1 kHz input, and 24 bit 44.1 or 88.2 kHz output. This is more than enough to very precisely equalize the whole audible range from 20 to 20000 Hz. The equalizer can be used as, and was designed for, a key component in a room equalization system. Non-realtime operation is also possible on slower machines.
