Tired of Matlab? Want more numerical power than Python can offer? Lush is an easy-to-learn, open-source object-oriented programming language designed for researchers, experimenters, and engineers working in large-scale numerical and graphic applications. It is well suited for R&D work in signal/image processing, machine learning, computer vision, bio-informatics, data mining, statistics, and artificial intelligence.
Lush combines three languages in one: a very simple to use, weakly-typed lisp-like interpreted language, a strongly-typed compiled language with the same syntax, and the C language, which can be freely mixed with the other languages within a single source file, and even within a single function.
Lush has a library of over 14,000 functions and classes, some of which are simple interfaces to popular libraries: vector/matrix/tensor algebra, linear algebra (LAPACK, BLAS), numerical function (GSL), 2D and 3D graphics (X, SDL, OpenGL, OpenRM, PostScipt), image processing, computer vision (OpenCV), machine learning (gblearn2, Torch), regular expressions, audio processing (ALSA), and video grabbing (Video4linux).
Lush is Free Software (GPL) and runs under GNU/Linux, Solaris, Irix, and Windows with Cygwin. Lush is included in many Linux distros including Debian, Mandrake, Quantian, and others.
DjVu is a document format, a set of compression methods and a software platform for distributing scanned and digitally produced documents on the Web.
DjVu image files of scanned documents are typically 3-8 times smaller than PDF or TIFF-groupIV for bitonal and 5-10 times smaller than PDF or JPEG for color (at 300 DPI). DjVu versions of digitally produced documents are more compact and render much faster than the PDF or PostScript versions.
What is the advantage? If you are distributing a collection of document on CD-ROM, you can provide platform-independent full-text search without asking your users to install any software on their machine. If you publish a collection of documents on the web, you don't need to install any server-side scripts: search queries run entirely in the user's web browser.
