SQLite is a small, fast, embeddable SQL database engine that supports most of SQL92, including transactions with atomic commit and rollback, subqueries, compound queries, triggers, and views. A complete database is stored in a single cross-platform disk file. The native C/C++ API is simple and easy to use. Bindings for other languages are also available.
BitTorrent is a tool for copying files from one machine to another. FTP punishes sites for being popular. Since all uploading is done from one place, a popular site needs big iron and big bandwidth. With BitTorrent, clients automatically mirror files they download, making the publisher's burden almost nothing.
Linux NTFS provides Linux kernel drivers, a multiplatform NTFS library, and tools to create, resize, clone, rescue, query, label and fix NTFS volumes, and to undelete, resize, list, and query files for the filesystem used by Windows XP, 2003, 2000, NT4, and Vista. It also provides support for the Logical Disk Manager (LDM) that controls Windows' Dynamic Disks and is used to create software mirrors, stripes, and RAID.
BRL-CAD is a powerful constructive solid geometry solid modeling system that includes an interactive geometry editor, ray-tracing support for rendering and geometric analysis, path-tracing for realistic image synthesis, network distributed framebuffer support, and image and signal-processing tools.
Squid Analyzer parses the native access log format of the Squid proxy and reports general statistics about hits, bytes, users, networks, top URLs, and top second level domains. Statistic reports are oriented toward user and bandwidth control; this is not a pure cache statistics generator.
Jhead is a command line driven utility for extracting digital camera settings from the Exif format files used by many digital cameras. It handles the various confusing ways these can be expressed, and displays them as F-stop, shutter speed, etc. It is also able to reduce the size of digital camera JPEGs without loss of information, by deleting integral thumbnails that digital cameras put into the Exif header. If you need to add Exif support to a program, this is a simple program to cut and paste from. Many projects, including PHP, have reused code from this utility.
libfiu is a C library for fault injection. It provides functions to mark "points of failure" inside your code (the "core API"), and functions to enable/disable the failure of those points (the "control API"). The core API is used inside the code on which you want to perform failure injection. The control API is used inside the testing code in order to control the injection of failures.
U++ is a C++ cross-platform rapid application development suite focused on programmers' productivity without sacrificing runtime performance. Based on strictly deterministic design, it provides a viable alternative to garbage-collected platforms, even for business logic oriented problems.
