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.
nxlog is a modular, multi-threaded, high-performance log management solution with multi-platform support. In concept, it is similar to syslog-ng or rsyslog, but is not limited to Unix/syslog only. It can collect logs from files in various formats, receive logs from the network remotely over UDP, TCP, or TLS/SSL on all supported platforms. It supports platform-specific sources such as the Windows Eventlog, Linux kernel logs, Android device logs, local syslog, etc. Writing and reading logs to/from databases is also supported for many database servers. The collected logs can be stored into files, databases, or forwarded to a remote log server using various protocols. The old BSD Syslog and the newer IETF syslog standard (RFC 3164 and RFC 5424-5426) are fully supported by nxlog in addition to XML, JSON, CSV, GELF, and other custom formats. A key concept in nxlog is to be able to handle and preserve structured logs so there is no need to convert everything to syslog and then parse these logs again at the other side. It has powerful message filtering, log rewrite, and conversion capabilities. Using a lightweight, modular, and multi-threaded architecture which can scale, nxlog can process hundreds of thousands of events per second.
nxtvepg is a decoder and browser for Nextview, a subscription-free electronic TV program guide in the analog domain. Nextview EPG currently is broadcast in Germany, Austria, Switzerland, Belgium, France, and Turkey, and it covers the schedules of all major TV networks in these countries. nxtvepg is an X11 application with a GUI based on Tcl/Tk and uses video4linux or BSD bktr drivers for data acquisition through a TV tuner card.
nyu is a combination of modern academic approaches to parsing formal grammars from PEGs and expression grammars that represents the new state of the art in parser generators. nyu grammars are written in a powerful language based on PEGs (parsing expression grammars) but with modifications to allow both the AST and the parser to be specified intuitively in a single grammar. nyu outputs parsers that take advantage of the chilon::parser meta-programming library for C++. The generated parsers are almost as concise and readable as the input grammars, yet perform as well as hand-written C code. nyu ASTs are built using tuples, variant types, and lists, and allow self referential parsers and AST nodes to be manipulated. Advanced features such as hashed containers and grammar inheritance are also possible and well tested. nyu is currently powerful enough to deal with complex grammars and bootstraps its own parser.
oFEd is a simple desktop application allowing you to format your text with BBCode text formatting and saving it to a text file. It's useful for people who write long tutorials and posts in forums and hate being logged constantly in the forum while writing. With oFEd you have a fullscreen editor and almost all the features needed to write your tutorial, overview, or other document and post it later when you are ready and want it.
