XCP-ng is a virtualization platform based on Xen Source and Citrix® Hypervisor (formerly XenServer). XCP-ng stands for Xen Cloud Platform - New Generation and is a tribute to the old Open Source project XCP, which was abandoned when XenServer was open-sourced in 2013.

Fetchmail is a full-featured, robust, well-documented remote-mail retrieval and forwarding utility intended to be used over on-demand TCP/IP links (such as SLIP or PPP connections). It supports every remote-mail protocol now in use on the Internet: POP2, POP3, RPOP, APOP, KPOP, all flavors of IMAP, ETRN, and ODMR. It can even support IPv6 and IPSEC. 
 
Fetchmail retrieves mail from remote mail servers and forwards it via SMTP, so it can then be read by normal mail user agents such as mutt, elm(1) or BSD Mail. It allows all your system MTA's filtering, forwarding, and aliasing facilities to work just as they would on normal mail. Fetchmail can be used as a POP/IMAP-to-SMTP gateway for an entire DNS domain, collecting mail from a single drop box on an ISP and SMTP-forwarding it based on header addresses. (We don't really recommend this, though, as it may lose important envelope-header information. ETRN or a UUCP connection is better.)

Librecast is a project to provide fast, efficient and scalable communication by leveraging IPv6 multicast. Librecast will allow disconnected multicast networks to communicate, enabling multicast applications to have the same reach and reliability as their unicast counterparts, thus making multicast communication a viable option for software developers.

Monkey HTTP Daemon, is a very Small, Fast and Lightweight open source Web Server for GNU/Linux. It has been designed to be very scalable with low memory and CPU consumption, the perfect solution for embedded and high production environments. It is asynchronous and event driven. It supports virtual hosts, SSL, Logs etc. 
 Monkey project includes an applications server called Palm, so when Monkey receives a dynamic page request, it will parse it and forward the request using the Palm protocol to the Palm server which will serve the request and Monkey sent back to the client the page generated.

ASCEND is an interactive environment for modeling, debugging, and solving large systems of nonlinear algebraic or differential equations. Oriented towards chemical engineering applications, it includes the largest open-source thermodynamic properties database. Its interactive design allows users to inspect and solve very difficult nonlinear systems. It includes plotting abilities and is scriptable.

Ohcount is a library for counting lines of source code. It was originally developed at Ohloh. It supports multiple languages within a single file: for example, a complex HTML document might include regions of both CSS and JavaScript.
 
Ohcount has two main components: a detector which determines the primary language family used by a particular source file, and a parser which provides a line-by-line breakdown of the contents of a source file.
It includes a command line tool that allows you to count individual files or whole directory trees. It also allows you to find source code files by language family, or to create a detailed annotation of an individual source file.

netsniff-ng is a free Linux networking toolkit, a Swiss army knife for your daily Linux network plumbing if you will. Its gain of performance is reached by zero-copy mechanisms, so that on packet reception and transmission the kernel does not need to copy packets from kernel space to user space and vice versa. 
 
 netsniff-ng is a fast network analyzer based on packet mmap(2) mechanisms. It can record pcap files to disc, replay them and also do an offline and online analysis. Capturing, analysis or replay of raw 802.11 frames are supported as well. pcap files are also compatible with tcpdump or Wireshark traces. netsniff-ng processes those pcap traces either in scatter-gather I/O or by mmap(2) I/O.

 SpatiaLite is an open source library intended to extend the SQLite core to support fully fledged Spatial SQL capabilities. SQLite is intrinsically simple and lightweight, It is a single lightweight library implementing the full SQL engine. SpatiaLite is smoothly integrated into SQLite to provide a complete and powerful Spatial DBMS (mostly OGC-SFS compliant). Using SQLite + SpatiaLite you can effectively deploy an alternative open source Spatial DBMS roughly equivalent to PostgreSQL + PostGIS.

The Open Network Install Environment (ONIE) is an open source initiative that defines an open "install environment" for modern networking hardware. ONIE enables an open networking hardware ecosystem where end users have a choice among different network operating systems.
 
Before the advent of ONIE, Ethernet switches were procured with pre-installed, captive operating systems, effectively creating networking appliances that locked end users into a vertical supply chain.
 
Modern network switches have a management subsystem, based on a variety of CPU architectures that typically include serial console, out-of-band Ethernet and mass storage. This subsystem can function independently from the switching ASIC(s) associated with the "front panel" Ethernet interfaces. ONIE defines an open source "install environment" that runs on this management subsystem utilizing facilities in a Linux kernel and BusyBox environment. This environment allows end users and channel partners to install the target NOS as part of data center provisioning, in the fashion that servers are provisioned.

Seafile is an open source cloud storage system with privacy protection and teamwork features. Collections of files are called libraries. Each library can be synced separately. A library can also be encrypted with a user chosen password. Seafile also allows users to create groups and easily sharing files into groups.
 
Seafile's version control model is similar to Git, but it is simplified for automatic synchronization. Each Seafile library behaves like a Git repository. It has its own unique history, which consists of a list of commits. A commit points to the root of a file system snapshot. The snapshot consists of directories and files. Files are further divided into blocks for more efficient network transfer and storage usage. However, Seafile doesn't rely on Git to run.

BeeGFS (formerly FhGFS) is the leading parallel cluster file system, developed with a strong focus on performance and designed for very easy installation and management. It transparently spreads user data across multiple servers. By increasing the number of servers and disks in the system, you can simply scale performance and capacity of the file system to the level that you need, seamlessly from small clusters up to enterprise-class systems with thousands of nodes.
