Rescatux is a GNU/Linux rescue CD that comes with Rescapp, a nice wizard that will guide you through your rescue tasks. It can restore Grub to the MBR update a Grub configuration, perform filesystem checks, fix a Windows MBR, and more. Features that can indirectly assist the rescue process include chat programs to let you reach human online help, a share log (automatic pastebin), and a share log that uses formatting appropriate for posting on a forum.
HAproxy is a high-performance and highly-robust TCP and HTTP load balancer which provides cookie-based persistence, content-based switching, SSL off-loading, advanced traffic regulation with surge protection, automatic failover, run-time regex-based header control, Web-based reporting and management interface, advanced logging to help trouble-shooting buggy applications and/or networks, and a few other features. Its own event-driven state machine achieves 100,000 connections per second and surpasses GigaEthernet on modern hardware, even with tens of thousands of simultaneous connections.
YourKit Java Profiler is a CPU and memory profiler that makes it easy to solve wide range of CPU- and memory-related performance problems. It features automatic leak detection, powerful tools for the analysis of memory distribution, an object heap browser, comprehensive memory tests as part of your JUnit testing process, extremely low profiling overhead, transparent deobfuscation support, and integration with Eclipse, JBuilder, IntelliJ IDEA, NetBeans, and JDeveloper IDEs.
Zero Install is a decentralized cross-distribution software installation system. It allows software developers to publish programs directly from their own Web sites, while supporting features familiar from centralized distribution repositories such as shared libraries, automatic updates, and digital signatures. It is intended to complement, rather than replace, the operating system's package management. 0install packages never interfere with those provided by the distribution.
For users on Linux and Unix, KDE offers a full suite of user workspace applications which allow interaction with these operating systems in a modern, graphical user interface. This includes Plasma Desktop, KDE's innovative and powerful desktop interface. Other workspace applications are included to aid with system configuration, running programs, or interacting with hardware devices. While the fully integrated KDE Workspaces are only available on Linux and Unix, some of these features are available on other platforms. In addition to the workspace, KDE produces a number of key applications such as the Konqueror Web browser, Dolphin file manager, and Kontact, the comprehensive personal information management suite. The list of applications includes many others, including those for education, multimedia, office productivity, networking, games, and much more. Most applications are available on all platforms supported by the KDE Development. KDE also brings to the forefront many innovations for application developers. An entire infrastructure has been designed and implemented to help programmers create robust and comprehensive applications in the most efficient manner, eliminating the complexity and tediousness of creating highly functional applications.
Armadillo is a C++ linear algebra library (matrix maths) aiming towards a good balance between speed and ease of use. The API is deliberately similar to Matlab's. Integer, floating point, and complex numbers are supported, as well as a subset of trigonometric and statistics functions. Various matrix decompositions are provided through optional integration with LAPACK and ATLAS numerics libraries. A delayed evaluation approach, based on template meta-programming, is used (during compile time) to combine several operations into one and reduce or eliminate the need for temporaries.
Reportico is a PHP reporting tool. It can create a report from a single SQL command and then build a whole suite of reports with criteria entry, graphs, groups, drill-downs, and expression handling. You can perform data transformation with your own custom PHP code. It can produce output in HTML, PDF, CSV, XML, and JSON.
