The PCI Utilities package contains various utilities dealing with the PCI bus, and also a library for portable access to PCI configuration registers. It includes `lspci' for listing all PCI devices (very useful for debugging of both kernel and device drivers) and `setpci' for manual configuration of PCI devices.
The Network Time Protocol (NTP) is used to synchronize the time of a computer client or server to another server or reference time source, such as a radio or satellite receiver or modem. It provides client accuracies typically within a millisecond on LANs and up to a few tens of milliseconds on WANs relative to a primary server synchronized to Coordinated Universal Time (UTC) via a Global Positioning Service (GPS) receiver, for example.
GlusterFS is a clustered filesystem capable of scaling to several petabytes. It aggregates various storage bricks over Infiniband RDMA or TCP/IP interconnect into one large parallel network file system. GlusterFS is based on a stackable user space design without compromising performance. It allows access via Swift API, SMB, NFSv3, QEMU/KVM, OpenStack Compute, OpenStack Block Storage, Xen, CloudStack, HDFS API, oVirt, and more, all in a unified backend which enables multiple, simultaneous access points to the same data stores.
GNUnet is a peer-to-peer framework with focus on providing security. All peer-to-peer messages in the network are confidential and authenticated. The framework provides a transport abstraction layer and can currently encapsulate the network traffic in UDP, TCP, HTTP, HTTPS, or direct 802.11 (WLAN). GNUnet supports accounting to provide contributing nodes with better service. The services built on top of the framework include anonymous file sharing and a virtual network providing IPv4-IPv6 transition via protocol translation over the P2P network.
JBIG-KIT implements a highly effective data compression algorithm for bi-level high-resolution images such as fax pages or scanned documents. It provides a portable C library of compression and decompression functions with a documented interface that can easily be included into image or document processing software. In addition, JBIG-KIT provides ready-to-use compression and decompression programs with a simple command line interface (similar to the converters found in netpbm). It implements the specification ISO 11544 and ITU-T T.82, which is commonly referred to as the "JBIG1 standard".
wasora is a computational tool designed to aid a cognizant expert, whether an engineer, scientist, technician, or geek, to analyze complex systems by solving mathematical problems by means of a high-level plain-text input file containing algebraic expressions, data for function interpolation, differential equations, and output instructions amongst other facilities. At first glance, it may look like another high-level interpreted programming language, but it should be seen as a syntactically-sweetened way to ask a computer to perform a certain mathematical calculation. For example, the famous Lorenz system may be solved by writing the three differential equations in a human friendly plain text file.
C-ICAP Classify is a module that allows classification (labeling) of Web pages, images, and soon video based on content. Labels are placed in HTTP headers. Any PIC-Label META tags are exported into HTTP headers. This allows for creation of very flexible filters according to rules defined by the user, using the ICAP enabled proxy's ACLs. It is not a URL filter, so implementing it with sslBump or similar proxy technologies makes it very difficult to bypass. Text classification is done using Fast Hyperspace (based on Hyperspace from CRM114) and/or a Fast Naive Bayes. Image and video (when implemented) use haar feature detection from the OpenCV library.
