feh is a fast, lightweight image viewer that uses imlib2. It is command line-driven and supports multiple images through slideshows, thumbnail browsing or multiple windows, and montages or index prints using TrueType fonts to display file information. Advanced features include fast dynamic zooming, progressive loading, loading via HTTP (with reload support for watching webcams), recursive file opening (slideshow of a directory hierarchy), and mouse wheel and keyboard control.
NSH is a CLI intended for OpenBSD-based network appliances. It replaces ifconfig, sysctl, and route with its own simple command language, and consolidates configuration for other daemons into one place, effectively replacing /etc/netstart and parts of /etc/rc for appliance-style usage. NSH presents the user with a vaguely Cisco-like interface with all configuration in one easy to read text list. It also gives the user access to system information and diagnostics. NSH replaces the userland commands that handle these functions, and talks directly to the OpenBSD kernel or control utility for daemon functionality. Supported external utilities: pf, ospfd, ospf6d, bgpd, ripd, ldpd, relayd, ipsecctl, iked, rtadvd, dvmrpd, sasyncd, dhcpd, snmpd, sshd, ntpd, ifstated, tftp-proxy, ftp-proxy, tftpd, npppd, resolv.conf, inetd, smtpd, ldapd, and ifstated.
Activity Manager is a project management tool that is simple to use, lightweight, and very efficient and customizable. It features collaborators repository administration, tasks repository administration, contributions management (activity management), and an extensible report facility (with built in templates). It allows you to build and maintain a hierarchical task tree. It is based on a database with a very simple model that allows quickly building custom reports through the report facility or through simple SQL requests.
Libtrading is a C library for trading securities, foreign exchange, and financial derivatives electronically. It implements market data, order entry, drop copy, and related communications protocols used by exchanges and alternative trading venues across the world. The library is designed for high performance and robustness. Although latency is very important in trading today's markets, achieving it it must not jeopardize trading reliability.
Scala is a modern multi-paradigm programming language designed to express common programming patterns in a concise, elegant, and type-safe way. It smoothly integrates features of object-oriented and functional languages including mixins, algebraic datatypes with pattern matching, genericity, and more. It is well integrated with Java and .NET: the Scala compiler produces standard Java class files or .NET assemblies, and Java/.NET libraries and frameworks can be used without glue code or additional declarations.
timeplotters is a collection of command line tools for visualizing temporal data. It is especially useful for visualizing data from ad-hoc program logs, helping you to spot patterns and anomalies that you would not otherwise see by just watching how the program works or by looking at the logs with the naked eye. Its input format is tailored to event types typically seen in program logs, and the visualization methods are tailored to the questions typically asked about program performance (e.g. distribution of activity durations).
