Cedar Backup is a software package designed to manage system backups for a pool of local and remote machines. Cedar Backup understands how to back up filesystem data as well as MySQL and PostgreSQL databases and Subversion repositories. It can also be easily extended to support other kinds of data sources. Cedar Backup is focused around weekly backups to a single CD or DVD disc. It supports multisession discs, allowing you to add incremental data to a disc on a daily basis. Cedar Backup also provides a Python library of backup-related functionality.
bitstring is a Python module that helps to make the creation and analysis of binary data as simple and natural as possible. Objects can be constructed from integers (big and little endian), floats, hex, octal, binary, byte data, iterables, or files. They can be sliced, joined, reversed, packed, unpacked, inserted into, overwritten, and otherwise operated upon with simple functions or slice notation. They can also be parsed, searched, and navigated in, similar to a file or stream. Internally the data is efficiently stored as byte arrays. It is available for Python 2.6 and later (including Python 3).
GeoTypes is a Python library that implements both the OpenGIS/PostGIS and standard PostgreSQL geometry types. It integrates with the psycopg Python/PostgreSQL interface. It provides implementations of all of the OpenGIS/PostGIS classes, except (x,y,m) and (x,y,z,m). It currently supports the EWKB, HEXEWKB, WKB, and WKT formats.
pyratemp is probably (one of) the smallest complete template-engines for Python (with less than 500 LOC). It has a very small set of special syntax in the templates. These features reduce complexity and the probability of bugs and lead to an easy-to-use and intuitive user-interface. It uses embedded Python-expressions (in a "sandbox"), is well documented, has full Unicode-support, and produces very good error-messages, which is very useful when creating new templates.
Python Audio Tools is a collection of audio handling programs that work from the command line. These include programs for CD extraction, track conversion from one audio format to another, track renaming and retagging, track identification, CD burning from tracks, and more. It supports internationalized track filenames and metadata using Unicode. It works with high-definition, multi-channel audio as well as CD-quality. Track conversion uses multiple CPUs or CPU cores if available to greatly speed the transcoding process. Track metadata can be retrieved from MusicBrainz, FreeDB, or compatible servers. Audio formats supported are WAV, FLAC, WavPack, MP3, Ogg Vorbis, M4A, Apple Lossless, and more.
Mrs is a lightweight but high performance implementation of the MapReduce programming model for parallel computation. It is optimized for computationally intensive programs, especially those which are iterative, though it is applicable to a wide range of applications. It is intended to be simple to install and use. It is written in Python, supports both Python 2 and Python 3, and has no dependencies outside the standard library. The name "Mrs" derives from the practice of referring to MapReduce programs by the title "mister" (e.g., "Mr. Wordcount").
