dd_rescue copies data from one file or block device to another. It is intended for error recovery, so by default, it doesn't abort on errors and doesn't truncate the output file. It uses large block sizes to quicken the copying, but falls back to small blocks upon encountering errors. It produces reports that allow you to keep track of bad blocks. dd_rescue features a number of optimizations, such as sparse block detection, preallocation, and Linux zerocopy (splice). It supports data protection by (multi-pass) overwriting of files or partitions with good and fast random numbers.
Flowgrind is a tool similar to iperf or netperf. It measures throughput and other metrics for TCP and other protocols. It features some unique characteristics: a distributed architecture, sophisticated flow scheduling, Linux kernel TCP statistics, the Anderson-Darling statistical test, rate-limited flows with uniform or Poisson distribution, and separation between control and test traffic.
GRASS (the Geographic Resources Analysis Support System) is a software raster- and vector-based GIS (Geographic Information System), image processing system, graphics production system, and spatial modeling system. It contains many modules for raster data manipulation, vector data manipulation, rendering images on the monitor or paper, multispectral image geocoding and processing, point data management and general data management. It also has tools for interfacing with digitizers, scanners, and the PostgreSQL, DBF, and ODBC connected databases. GRASS operates on all common operating systems.
dbf is an easy-to-use command line tool to show and convert the content of dBASE III, IV, and 5.0 files, as well as of FoxBase and Visual FoxPro. It reads xBASE-compatible databases and prints the content to the screen or converts it to comma-separated (*.csv) files which can be opened in Excel, StarOffice, and most other spread sheets. It can also be used to show some statistics about the content.
gumnut is a program to find the most supported proposals within large groups of people. The text or GUI client can create, moderate, and display proposals over a decentralized communication network (currently Gnutella). Proposals are text files with a simple naming convention that uses the filename to describe field attributes (such as topic and geographical location). Popular proposals are found by searching on one or more of these fields and then calculating the support for each proposal based on the number of occurrences on the network.
Fiwix is an operating system kernel based on the Unix architecture and fully focused on being Linux compatible. It is designed exclusively for educational purposes, so the kernel code is kept as simple as possible for the benefit of students. It runs on the 32-bit x86 hardware platform, and is compatible with a good base of existing GNU applications.
The Legend of Edgar is a 2D platform game with a persistent world. When Edgar's father fails to return home after venturing out one dark and stormy night, Edgar fears the worst: he has been captured by the evil sorcerer who lives in a fortress beyond the forbidden swamp. In The Legend of Edgar, you take on the role of Edgar as he ventures across the world, battling fearsome creatures and solving puzzles while trying to find and rescue his father.
Python is an interpreted, interactive, object-oriented programming language. It combines remarkable power with very clear syntax, and isn't difficult to learn. It has modules, classes, exceptions, very high level data types, and dynamic typing. There are interfaces to many system calls and libraries, as well as to various windowing systems (Tk, Mac, MFC, GTK+, Qt, wxWindows). New built-in modules are easily written in C or C++. Python is also usable as an extension language for applications that need a programmable interface.
FLOM is a distributed lock manager that can be used to avoid shell tricks and safely execute different tasks that cannot run at the same time. It manages process serialization in the same way nice manages process prioritization. It implements the same lock mode semantic proposed by VMS DLM to allow non-trivial command serialization use cases. The goal is to "just work"; everything implemented must be useful and easy to use (configuration is reduced to a bare minimum). It works inside a single system or in a network of IP connected systems.
