NASM is an 80x86 assembler designed for portability and modularity. It supports a range of object file formats including Linux a.out and ELF, COFF, Microsoft 16-bit OBJ, Win32/64, and Apple Mach-O. It will also output plain binary files. Its syntax is designed to be simple and easy to understand, similar to Intel's but less complex. It supports all currently known opcodes, and has advanced macro capability. It includes a disassembler as well.
NOC Project is an Operation Support System (OSS) for telecom companies, service providers, and enterprise Network Operation Centers (NOC). Areas covered by NOC include fault management, performance management, service activation/provisioning, knowledge base, multi-VRF address space management (IPAM), multi-vendor configuration management, DNS provisioning, peering management, RPSL and BGP filter generation, and reporting.
NRL OLSR is the NRL's implementation of the OLSR ad-hoc mobile network routing protocol, using RFC 3626 packet formats. It supports IPv4 and IPv6. Support for Ethereal and NS2 exists but may not be current. NRL's implementation is derived from INRIA's OLSR software router, which is also available.
Netdisco is a Web-based network management tool. Users can locate the switch port of an end-user system by IP or MAC address. Data is stored using a SQL database. Cisco Discovery Protocol (CDP) optionally provides automatic discovery of the network topology. The network is inventoried by both device model and operating system (like IOS). It uses router ARP tables and L2 switch MAC forwarding tables to locate nodes on physical ports and track them by their IP addresses. For each node, a time stamped history of the ports it has visited and the IP addresses it has used is maintained. It gets all its data, including CDP topology information, with SNMP polls and DNS queries. Security features include a wire-side Wireless Access Point (AP) locator.
Neveredit aims to provide end-user module editing facilities for Bioware's Neverwinter Nights computer game. It parses and writes most NWN files and provides a convenient interface to change a growing number of attributes of the module they constitute. For developers, it provides a set of Python classes that can be used to manipulate NWN files at two layers of abstraction.
NoSpex is a Python scripted realtime graphing library designed to be easily employed by security consultants and reverse engineers for teasing apart and depicting the relationships between processes in a system under analysis. It is realtime in the sense that the graph is continuously rendered and animated as new relationships are introduced. It is easily employed in the sense that all the bookkeeping is done by the Python module and exposed using a simple thread-safe API. NoSpex relies on the SDL graphic library for a frame buffer and Cairo for rendering to the frame buffer. This combination produces a fast and visually elegant graph that should be portable wherever SDL and Cairo can be found.
Notational Velocity is a Mac OS X desktop application that stores and retrieves notes. The same area is used both for creating notes and searching. I.e., in the process of entering the title for a new note, related notes appear below, letting users file information there if they choose. Likewise, if a search reveals nothing, one need simply press return to create a note with the appropriate title.
NoteFinder is an application for managing any text information: notes, quotes, conversations, drafts, articles, contacts, etc. It features creating, viewing, editing, renaming, deleting entries, rich text formatting, inline calculations (e.g., use ~7+8~ to get 15, or functions and constants from Python's math module, such as sqrt, sin, and pi), organizing entries chronologically (creation dates) and semantically (tags), advanced search (with date:, tag:, title:, year:, month:, and day: parameters), saving searches, multiple notebooks, multiple backends, the ability to move/copy entries from one notebook to another, synchronizing via email/Wiki, linking entries together, CamelCase links support, and a tabbed interface.
