PyInstaller is a program that converts (packages) Python programs into stand- alone executables, under Windows, Mac OS X, and Unix-like operating systems. Its main advantages over similar tools are that PyInstaller works with any version of Python since 2.4, it builds smaller executables thanks to transparent compression, it is fully multi-platform, and uses the OS support to load the dynamic libraries, thus ensuring full compatibility. The main goal of PyInstaller is to be compatible with third-party packages out-of-the-box. This means that, with PyInstaller, all the required tricks to make external packages work are already integrated within PyInstaller itself so that there is no user intervention required.

simplejson is a simple, fast, extensible JSON encoder/decoder for Python simplejson is compatible with Python 2.4 and later with no external dependencies. It covers the full JSON specification for both encoding and decoding, with unicode support. By default, encoding is done in an encoding neutral fashion (plain ASCII with \uXXXX escapes for unicode characters). The encoder may be subclassed to provide serialization in any kind of situation, without any special support by the objects to be serialized (somewhat like pickle). The decoder can handle incoming JSON strings of any specified encoding (UTF-8 by default).

Python bindings for Newt toolkit. Newt is a windowing toolkit for text mode built from the slang library. It allows color text mode applications to easily use stackable windows, push buttons, check boxes, radio buttons, lists, entry fields, labels, and displayable text. Scrollbars are supported, and forms may be nested to provide extra functionality. Besides the newt library, this port provides whiptail, which may be used from shell scripts similarly to Savio Lam's "dialog". Newt provides the textual interface for the Red Hat and Debian boot disks.

A Ruby gem to manage ISO 3166 country names and their corresponding alpha-2 and alpha-3 codes. Additional support has been added for ISO 4127 currency information and standard conventions for states in the USA (based on the 3166-2:US code). ISO 3166 country codes reference: http://en.wikipedia.org/wiki/ISO_3166-1 ISO 4217 currency information: http://www.xe.com/iso4217.php http://www.xe.com/symbols.php ISO 3166-2:US code reference: http://code.google.com/apis/chart/statecodes.html http://en.wikipedia.org/wiki/ISO_3166-2:US ISO 639 language reference: http://en.wikipedia.org/wiki/List_of_ISO_639-1_codes

The Sigar API provides a portable interface for gathering system information such as: * System memory, swap, cpu, load average, uptime, loginsi * Per-process memory, cpu, credential info, state, arguments, environment, open files * File system detection and metrics * Network interface detection, configuration info and metrics * TCP and UDP connection tables * Network route table This information is available in most operating systems, but each OS has their own way(s) providing it. SIGAR provides developers with one API to access this information regardless of the underlying platform. The core API is implemented in pure C with bindings currently implemented for Java, Perl, Ruby, Python, Erlang, PHP and C#.

SMACK is a low-level I/O storage library which packs data into sorted blobs, compressed with zlib, bzip2, or snappy. It was created to host huge amount of rather small compressible data in Elliptics, providing extremely fast write performance (tens of thousands RPS per node with hundreds of millions already written objects); its backend architecture was implemented with HBase in mind, but some changes were tested and made different. Data is compressed and sorted by key, that is, you get HBase-like scans for free (although this is not yet exported to Elliptics API).

XXL is a library for C and C++ that provides exception handling and asset management. Asset management is integrated with the exception handling mechanism such that assets may be automatically cleaned up if an exception is thrown, which allows for much simplified program structure with respect to error handling. By allowing XXL to track assets and using its exception handling features, the programmer no longer has to check error conditions on every function call and cleanup the assets on failure because XXL does the work.

GNU uCommon C++ is meant as a very light-weight C++ library to facilitate using C++ design patterns even for very deeply embedded applications, such as for systems using uclibc along with posix threading support. For this reason, GNU uCommon C++ disables language features that consume memory or introduce runtime overhead, such as rtti and exception handling, and assumes one will mostly be linking applications with other pure C based libraries rather than using the overhead of the standard C++ library and other similar class frameworks.

GNU Libidn is an implementation of the Stringprep, Punycode, and IDNA specifications defined by the IETF Internationalized Domain Names (IDN) working group. It is used to prepare internationalized strings (such as domain name labels, usernames, and passwords) in order to increase the likelihood that string input and string comparison work in ways that make sense for typical users throughout the world. The library contains a generic Stringprep implementation that does Unicode 3.2 NFKC normalization, mapping and prohibition of characters, and bidirectional character handling. Profiles for iSCSI, Kerberos 5, Nameprep, SASL, and XMPP are included. Punycode and ASCII Compatible Encoding (ACE) via IDNA are supported.

ez-ipupdate is a small utility for updating your host name if you are using any of the following dynamic DNS services: http://gnudip.cheapnet.net (GNUDip) http://www.dhs.org http://www.dyn.ca (GNUDip) http://www.dyndns.org http://www.dyns.cx http://www.easydns.com http://www.ez-ip.net http://www.hn.org http://www.justlinux.com http://www.ods.org http://www.tzo.com http://www.zoneedit.com It is pure C and works on Linux, *BSD and Solaris. The key features are: support for multiple service types, daemon mode that monitors your IP address and only sends updates when your IP address changes.
