Subversion is a version control system. Originally designed to be a compelling replacement for CVS in the open source community, it has far exceeded that goal and seen widespread adoption in both open source and corporate environments. The Subversion project produces Subversion's core libraries (written in C), a fully functional command line client (svn), repository administration programs, API bindings for various languages (Perl, Python, Java, Ruby, etc.), and various additional tools and scripts.
MirrorBrain is a framework to run a content delivery network using mirror servers. It solves a challenge that many popular open source projects face: a flood of download requests, often magnitudes more than a single site could practically handle. A central (and probably the most obvious) part is a "download redirector" that automatically redirects requests from Web browsers or download programs to a mirror server near them. Choosing a suitable mirror for a user's request is the key, and MirrorBrain uses geolocation and global routing data to make a sensible choice and achieve load-balancing for the mirrors at the same time. The algorithm is both sophisticated and easy to control and tune. In addition, MirrorBrain monitors mirrors, scans them for files, generates mirror lists, and more.
Conary is a distributed software management system for Linux distributions. It replaces traditional package management solutions (such as RPM and dpkg) with one designed to enable loose collaboration across the Internet. It enables sets of distributed and loosely connected repositories to define the components which are installed on a Linux system. Rather than having a full distribution come from a single vendor, it allows administrators and developers to branch a distribution, keeping the pieces which fit their environment while grabbing components from other repositories across the Internet.
Meson aims to be the most usable and fast build system. It provides a simple yet powerful mostly declarative language for describing your build. It has native support for modern tools and frameworks, such as Qt5, code coverage, unit tests, precompiled headers, and others. It utilizes a host of optimization techniques to compile your code faster on both full and incremental builds.
The svnmailer is a tool that is usually called by a subversion hook to submit commit notifications in various ways (at the moment: mail via SMTP or a pipe to a sendmail like program, news via NNTP, or CIA live tracker notification via XML-RPC). It is derived from the original mailer.py distributed with subversion, but should be much more consistent, more extensible, and have many more features.
Chandler is a standards-based "Note-to-Self Organizer" designed for personal and small-group task management and calendaring. It consists of a desktop application and Chandler Hub, a free sharing service and Web application. You can also download and run your own Chandler Server.
mrtparse is a module to read and analyze the MRT data format. The MRT format can be used to export routing protocol messages, state changes, and routing information base contents, and is standardized in RFC6396. Programs like Quagga/Zebra, BIRD, OpenBGPD, and PyRT can dump to MRT.
namebench finds the best DNS servers to use for your machine, benchmarks them, and outputs pretty graphs to tell you why they are optimal. It supports multiple data sources such as Alexa, your browser history, or tcpdump replays in order to generate the most relevant and individualized recommendation.
The Android Scripting Environment (ASE) brings scripting languages to Android by allowing you to edit and execute scripts and interactive interpreters directly on the Android device. These scripts have access to many of the APIs available to full-fledged Android applications, but with a greatly simplified interface that makes it easy to handle intents, start activities, make phone calls, send text messages, scan bar codes, poll location and sensor data, use text-to-speech, and more. Scripts can be run interactively in a terminal, started as a long running service, or started via Locale. Python, Perl, JRuby, Lua, BeanShell, and Bourne shell are currently supported.
