Bandwidth is primarily a memory bandwidth benchmark, but it can also measure network bandwidth. It measures the maximum memory bandwidth of each part of the memory system, including main memory, L1, L2, and L3 caches, framebuffer memory, and register-to-register. For many tests, it performs both sequential memory accesses as well as random memory accesses to provide a more real-world performance estimate. The tests support Linux (Intel), Windows/Cygwin, and Mac OS X. Its core routines are in assembly for x86 and x86-64 architectures with both SSE4 and AVX support. Bandwidth also includes automatic graphing of the results, stored to a BMP image file. The network bandwidth tests support Linux, Mac OS X, and Windows/Cygwin.
SHOGUN is a machine learning toolbox whose focus is on large scale kernel methods and especially on Support Vector Machines (SVM). It provides a generic SVM object interfacing to several different SVM implementations, all making use of the same underlying, efficient kernel implementations. Apart from SVMs and regression, SHOGUN also features a number of linear methods like Linear Discriminant Analysis (LDA), Linear Programming Machine (LPM), (Kernel) Perceptrons, and algorithms to train hidden Markov models. SHOGUN can be used from within C++, Matlab, R, Octave, and Python.
Racket (formerly PLT Scheme) is a programming language suitable for implementation tasks ranging from scripting to application development, including GUIs, Web services, etc. It includes the DrRacket programming environment, a virtual machine with a just-in-time compiler, tools for creating stand-alone executables, the Racket Web server, extensive libraries, documentation for both beginners and experts, and more. It supports the creation of new programming languages through a rich, expressive syntax system. Example languages include Typed Racket, ACL2, FrTime, and Lazy Racket.
Calcurse is a text-based calendar and scheduling application. It helps keep track of events, appointments, and everyday tasks. A configurable notification system reminds the user of upcoming deadlines, and the curses based interface can be customized to suit user needs. All of the commands are documented within an online help system.
Mintty is a terminal emulator for Cygwin and MSYS with a native Windows user interface and minimalist design. It is based on parts of PuTTY by Simon Tatham and provides xterm-compatible terminal emulation, but does not require an X server. Its features include a simple options dialog, Unicode support, fullscreen mode, drag & drop, and window transparency.
PBZIP2 is a parallel implementation of the bzip2 block-sorting file compressor that uses pthreads and achieves near-linear speedup on SMP machines. The output of this version is fully compatible with bzip2 1.0.2 or newer (ie: anything compressed with PBZIP2 can be decompressed with bzip2).
Enblend is a postprocessing tool for creating panoramic images. After you align image features using a program like Hugin, there are often photometric problems that lead to ugly seams in the final composite. Enblend blends away these seams using a multiresolution spline. This technique gives good results on both low spatial frequency objects (sky and clouds) and high spatial frequency objects (trees and houses).
