PDFTextStream is a PDF text and metadata extraction library available for Java and .NET. It supports all versions of the PDF document specification (including v1.7, used by Acrobat 8, 9, and X), extraction of text encoded using double-byte character sets (including Chinese, Japanese, and Korean), decryption of documents encrypted using 40-bit, 128-bit, 256-bit, and variable bit length ciphers, and extraction of all document metadata provided by PDF documents (including form data, bookmarks, and annotations). Easy integration with Jakarta Lucene is included, as well as interactive form update capability.
Electron Gamma Shower (EGS) is a general purpose package for the Monte Carlo simulation of the coupled transport of electrons and photons in an arbitrary geometry for particles with energies from a few keV up to several TeV. Simulations can be performed in arbitrarily complex physical geometries, and a wide range of physical processes are modeled.
phalanx computes a digest of many buffers simultaneously, and produces a combined hash of them all. It is an initiative to provide a fast, simple, and portable alternative method to compute a checksum in a parallel fashion. It has options for I/O buffer size, hash width, number of threads, and more. It can be run single-threadedly for performance comparisons. It can check files against previously-saved sums, like "MD5sum" does. It also has a "demo" mode, to ascertain accurate operation. It is intended to be useful on large files and multicore/multiprocessor/multithreaded environments.
Meep is a free finite-difference time-domain (FDTD) simulation software package to model electromagnetic systems. It supports distributed-memory parallel simulations, nonlinear, anisotropic, and dispersive media, PML absorbing boundaries, and 1D/2D/3D and cylindrical problems. It is completely scriptable from either C++ or a Scheme (GNU Guile) interface.
crosstool-NG is a versatile toolchain generator, aiming at being highly configurable. It supports multiple target architectures, different components (glibc/uClibc...) and versions. crosstool-NG also features debugging utilities (DUMA, strace...) and generation tools (sstrip...).
offrss is a standalone program that can download your favorite feeds and then show them in your favorite Web browser by spawning a simple local Web server. It will not only download the feeds' text, but also the pictures, so you will also be able to read comics strips and enjoy posts with pictures in them while offline. It can also generate PDFs from text. It remembers what you read and what you don't, and all the information stays in normal files, so you can synchronize it easily to any device that may not have an Internet connection. It can also work as a CGI to serve your feeds in your Web site, and it can update the feeds from crontab. It has few dependencies to build and can be cross compiled easily.
