ANN: BlitzDB 0.1 - Embedabble, document-oriented database written entirely in Python

by andreas.d＠posteo.de

Hi all, I just released the first version (0.1) of BlitzDB, an embeddable, document-based database written entirely in Python. The software is open-source and released under the MIT license, the code is available on Github: https://github.com/adewes/blitzdb The documentation is hosted on ReadTheDocs: http://blitz-db.readthedocs.org The database ships with a native, file-based backend that has no external dependencies. In addition, it can be used as a wrapper around third-party database engines such as MongoDB. Some more features: * document-based, object-oriented interface * powerful and rich querying language comparable to MongoDB * deep document indexes on arbitrary fields * compressed storage of documents * support for multiple backends (e.g. file-based storage, MongoDB) * support for database transactions (currently only for the file-based backend) The current, fully functional release is on PyPi (https://pypi.python.org/pypi/blitzdb/0.1) and can be installed using e.g. pip or easy_install: pip install blitzdb #or easy_install blitzdb The main motivation for writing this was to create an embeddable, document-oriented database that I could use in my Python projects (e.g. command line tools) without having to worry about setting up and maintaining additional software or servers. The project is NOT intended as a fully-fledged replacement for MongoDB or other document databases. I would love to hear your feedback on this project and I'm actively looking for contributors, so feel free to get in touch with me (you can find my e-mail on Github). Best regards Andreas <a href="http://blitz-db.readthedocs.org">BlitzDB 0.1</a> BlitzDB 0.1 - Embedabble, document-oriented database written entirely in Python

Nose 1.3.1 released

by John Szakmeister

It's been nearly a year since the last release, and this one brings about 30+ fixes--a couple of the big ones include better Unicode support when capturing output and compatibility with Python 3.4. Thank you to all those who contributed to this release, and a special thanks goes to Thomas Kluyver for all the code reviews and insights while sorting out Unicode-related issues. See the CHANGELOG for the details of what was fixed and the person to thank for fixing it. It's also time to acknowledge that nose 1.x is in maintenance mode. We will not be looking to add any features, and you should seriously consider looking at nose2 as the way forward. If you're interested in the future of nose, please take a look at the nose2 project on github (https://github.com/nose-devs/nose2) or pypi (http://pypi.python.org/pypi/nose2/0.4.7). And lastly if you have the money to spare, please consider donating to the John Hunter memorial fund (http://numfocus.org/johnhunter/). We all give up time with our families to work on free software: so now the free software community that has benefited so much from that time we took can give something back to his family. -John

ANN: Bokeh 0.4.2

by Bryan Van de Ven

I am happy to announce the release of Bokeh version 0.4.2! Bokeh is a Python library for visualizing large and realtime datasets on the web. Its goal is to provide elegant, concise construction of novel graphics in the style of Protovis/D3, while delivering high-performance interactivity to thin clients. Bokeh includes its own Javascript library (BokehJS) that implements a reactive scenegraph representation of the plot, and renders efficiently to HTML5 Canvas. Bokeh works well with IPython Notebook, but can generate standalone graphics that embed into regular HTML. Check out the full documentation, interactive gallery, and tutorial at http://bokeh.pydata.org If you are using Anaconda, you can install with conda: conda install bokeh Alternatively, you can install with pip: pip install bokeh Some of the new features in this release include: * Additional Matplotlib and Seaborn compatibility (PolyCollection) * Extensive tutorial with exercises and solutions added to docs * new %bokeh magic for improved IPython notebook integration * Windows support for bokeh-server with two new storage backends (in-memory and shelve) Also, we've fixed lots of little bugs - see the CHANGELOG for full details. BokehJS is also available by CDN for use in standalone javascript applications: http://cdn.pydata.org/bokeh-0.4.2.js http://cdn.pydata.org/bokeh-0.4.2.css http://cdn.pydata.org/bokeh-0.4.2.min.js http://cdn.pydata.org/bokeh-0.4.2.min.css Some examples of BokehJS use can be found on the Bokeh JSFiddle page: http://jsfiddle.net/user/bokeh/fiddles/ The release of Bokeh 0.5 is planned for late March. Some notable features we plan to include are: * Abstract Rendering for semantically meaningful downsampling of large datasets * Better grid-based layout system, using Cassowary.js * More MPL/Seaborn/ggplot.py compatibility and examples * Additional tools, improved interactions, and better plot frame * Touch support Issues, enhancement requests, and pull requests can be made on the Bokeh Github page: https://github.com/continuumio/bokeh Questions can be directed to the Bokeh mailing list: bokeh(a)continuum.io Special thanks to recent contributors: Melissa Gymrek, Amy Troschinetz, Ben Zaitlen, Damian Avila, and Terry Jones Regards, Bryan Van de Ven Continuum Analytics http://continuum.io

mimedecode.py version 2.4.0

by Oleg Broytman

Hello! mimedecode.py WHAT IS IT Mail users, especially in non-English countries, often find that mail messages arrived in different formats, with different content types, in different encodings and charsets. Usually this is good because it allows us to use appropriate format/encoding/whatever. Sometimes, though, some unification is desirable. For example, one may want to put mail messages into an archive, make HTML indices, run search indexer, etc. In such situations converting messages to text in one character set and skipping some binary attachments is much desirable. Here is the solution - mimedecode.py. This is a program to decode MIME messages. The program expects one input file (either on command line or on stdin) which is treated as an RFC822 message, and decodes to stdout or an output file. If the file is not an RFC822 message it is just copied to the output one-to-one. If the file is a simple RFC822 message it is decoded as one part. If it is a MIME message with multiple parts ("attachments") all parts are decoded. Decoding can be controlled by command-line options. WHAT'S NEW in version 2.4.0 (2014-03-08) Change option -d to accept a comma-separated list of headers: -d h1,h2,h3,... Change option -d to decode all headers and accept a list of exceptions: -d *,-h1,-h2,... Change option -p to accept lists of headers and parameters: -p h1,h2,h3,..:p1,p2,p3,.. Allow * and exceptions for -p in the headers and parameters lists: -p *,-h1,-h2,-h3:p1,p2,p3 -p h1,h2,h3:*,-p1,-p2,-p3 -p *,-h1,-h2,-h3:*,-p1,-p2,-p3 Change option -r to accept a list of headers: -r h1,h2,h3,... Change option -r to remove all headers and accept a list of exceptions: -r *,-h1,-h2,... Change option -R to accept lists of headers and parameters: -R h1,h2,h3:p1,p2,p3 -R h1,h2,h3:*,-p1,-p2,-p3 -R *,-h1,-h2,-h3:p1,p2,p3 -R *,-h1,-h2,-h3:*,-p1,-p2,-p3 Publish docs in html format. Add ChangeLog. WHAT'S NEW in version 2.3.7 (2014-02-23) Add option -r to remove headers and option -R to remove headers parameters.
