nget is a commandline NNTP file grabber. It automatically pieces together multipart postings for easy retrieval, even substituting parts from multiple servers and newsgroups. It handles disconnects gracefully, resuming after the last part successfully downloaded, and caching of header data for quick access. It automatically downloads only as many par/par2 files as needed.
ngrep strives to provide most of GNU grep's common features, applying them to the network layer. ngrep is a pcap-aware tool that will allow you to specify extended regular or hexadecimal expressions to match against data payloads of packets. It currently recognizes IPv4/6, TCP, UDP, ICMPv4/6, IGMP and Raw across Ethernet, PPP, SLIP, FDDI, Token Ring, and null interfaces, and understands BPF filter logic in the same fashion as more common packet sniffing tools, such as tcpdump and snoop.
Ngspice is a mixed-level/mixed-signal circuit simulator based on three open source software packages: Spice3f5, Cider1b1, and Xspice. Spice3 is the most famous and widely used circuit simulator. Cider is mixed-level simulator that includes Spice3f5 and adds DSIM, a device simulator. Cider couples the circuit level simulator to the device simulator to provide greater simulation accuracy (at the expense of greater simulation time). Xspice is an extension to Spice3 that provides code modeling support and simulation of digital components through an embedded event driven algorithm.
noVNC is a VNC client implemented using HTML5 technologies, specifically Canvas and WebSockets. It supports "wss://" encryption (SSL/TLS). For browsers that do not have native WebSockets support, the project includes web-socket-js, a WebSockets emulator using Adobe Flash. In addition, as3crypto has been added to web-socket-js to implement WebSocket SSL/TLS encryption, i.e. the "wss://" URI scheme.
node-cassandra-cql is a Node.js CQL driver for the Apache Cassandra CQL3 binary protocol. CQL is a query language for Apache Cassandra. It features connection pooling to multiple hosts, parameters in queries, the ability to get a cell by column name using row.get('first_name'), and bigints support.
ns4 is a command line configuration management tool that runs on a Unix or Windows based operating system. It allows the automated backup of node (i.e. routers and switches) configurations to an FTP/SFTP server or local media on a daily basis to create configuration archives. It can run ad-hoc commands on multiple nodes as well as custom scripts for automating complex tasks. It uses Perl and allows you to manipulate the output of commands using regular expressions within scripts. Configuration based cartridges are used to specify new node types, allowing the user to extend its functionality in a simple and dynamic way.
