both commercial and non-commercial use.</p>

<p>Boost aims to establish &ldquo;existing practice&rdquo; and provide

reference implementations so that Boost libraries are suitable for

eventual standardization. Ten Boost libraries are already included in the

C++ Standards Committee's Library Technical Report (TR1) as a step toward

becoming part of a future C++ Standard. More Boost libraries are proposed

for the upcoming TR2.</p>

<h2><a href="https://www.bro.org/">Bro Network Security Monitor</a></h2>

<p>Bro provides a comprehensive platform for network traffic analysis, with a

particular focus on semantic security monitoring at scale. While often

compared to classic intrusion detection/prevention systems, Bro takes a quite

different approach by providing users with a flexible framework that

facilitates customized, in-depth monitoring far beyond the capabilities of

traditional systems. With initial versions in operational deployment during

the mid '90s already, Bro finds itself grounded in more than 20 years of

research.</p>

<h2><a href="http://buildbot.net/">Buildbot</a></h2>

<p>

Buildbot is a freely-licensed framework which enables software

developers to automate software build, test, and release processes for their

software projects.  First released in 2003, Buildbot is used by leading 

software projects around the world to automate all aspects of their 

software development cycle. </p>

<h2 id="busybox"><a href="https://busybox.net/">BusyBox</a></h2>

<p>BusyBox combines tiny versions of many common UNIX utilities into a

single small executable. It provides replacements for most of the

utilities you usually find in GNU fileutils, shellutils, etc. The

utilities in BusyBox generally have fewer options than their

full-featured GNU cousins; however, the options that are included

provide the expected functionality and behave very much like their GNU

counterparts. BusyBox provides a fairly complete environment for any

small or embedded system.</p>

<p>BusyBox has been written with size-optimization and limited

resources in mind. It is also extremely modular so you can easily

include or exclude commands (or features) at compile time. This makes

it easy to customize your embedded systems. To create a working

system, just add some device nodes in /dev, a few configuration files

in /etc, and a Linux kernel.</p>

<h2><a href="http://darcs.net/">Darcs</a></h2>

<p>Darcs is a distributed revision control system written in Haskell. In

Darcs, every copy of your source code is a full repository, which allows for

full operation in a disconnected environment, and also allows anyone with

read access to a Darcs repository to easily create their own branch and

modify it with the full power of Darcs' revision control. Darcs is based on

an underlying theory of patches, which allows for safe reordering and

merging of patches even in complex scenarios. For all its power, Darcs

remains a very easy to use tool for every day use because it follows the

principle of keeping simple things simple.  Darcs is free software

licensed under the GNU GPL.</p>

<h2><a href="/news/2015/aug/17/debian/">Debian Copyright Aggregation Project</a></h2>

<p>The Debian Copyright Aggregation Project offers contributors to

  the <a href="https://www.debian.org">Debian project</a> the optional

  opportunity, regarding their works contributed to Debian, to assign

  copyrights or sign a license enforcement agreement (which delegates to

  Conservancy the authority of license enforcement).  The Project also

  creates an ongoing relationship between Conservancy and Debian, wherein

  Conservancy offers Debian its expertise and advice on software licensing,

  enforcement, and related issues.</p>

<h2><a href="https://evergreen-ils.org/">Evergreen</a></h2>

<p>The Evergreen Project develops an open source ILS (integrated library

system) used by hundreds of libraries across the world. The software, also

called Evergreen, is used by libraries to provide their public catalog

interface as well as to manage back-of-house operations such as

circulation (checkouts and checkins), acquisition and cataloging of

library materials, and sharing resources among groups of libraries and

consortia on the same Evergreen system.  Evergreen is designed to be

scalable and supports library operations ranging from a small high school

to large state-wide consortia.  Evergreen is released under

the <a href="http://www.gnu.org/licenses/gpl-2.0.html">GPLv2</a>-or-later.</p>

<h2><a href="http://www.gevent.org/">Gevent</a></h2>

<p>Gevent is a fast, coroutine-based networking library for Python.

Gevent is used in network applications, including servers that scale

up to tens thousands of connections but without the complexity usually

associated with event-driven architecture.</p>

<p>Gevent provides light-weight &ldquo;green&rdquo; threads with a similar

interface as the standard “threading” and

“multiprocessing” packages.  The library includes a DNS

resolver, a WSGI server, a monkey patching utility to make 3rd party
