XML VFS 1.0.1 for Midnight Commander
by Oleg Broytman Nov. 25, 2013

Nov. 25, 2013

Hello! I'm pleased to announce an XML Virtual FileSystem for Midnight Commander version 1.0.1. WHAT IS IT View an XML file in Midnight Commander as a filesystem. WHAT'S NEW in version 1.0.1 (2013-11-24) Fixed a few minor bugs. WHAT'S NEW in version 1.0.0 (2013-11-23) With lxml.etree-based implementation show only child namespaces (calculated as combined namespaces minus parent's namespaces). WHAT'S NEW in version 0.6.0 (2013-11-22) Refactored _list() and attrs2text() to be completely generic. WHAT'S NEW in version 0.5.0 (2013-11-19) Added lxml.etree-based implementation. WHAT'S NEW in version 0.4.0 (2013-11-19) Added ElementTree-based implementation. WHAT'S NEW in version 0.3.0 (2013-11-16) Initial release. Implementation based on minidom. WHERE TO GET Home page: http://phdru.name/Software/mc/xml.html Download: http://phdru.name/Software/mc/xml git clone http://git.phdru.name/extfs.d.git git clone git://git.phdru.name/extfs.d.git Installation instructions: http://phdru.name/Software/mc/INSTALL.html The VFS represents tags as directories; the directories are numbered to distinguish tags with the same name; numbering also helps to sort tags by their order in XML instead of sorting them by name. Attributes, text nodes and comments are represented as text files; attributes are shown in a file named "attributes", attributes are listed in the file as name=value lines (I deliberately ignore a small chance of newline characters in values); names and values are reencoded to the console encoding. Text nodes and comments are collected in a file named "text", stripped and reencoded. The filesystem is read-only. Implementation based on minidom doesn't understand namespaces, it just shows them among other attributes. ElementTree-based implementation doesn't show namespaces at all. Implementation based on lxml.etree shows namespaces in a separate file "namespaces". It is useful to have a top-down view on an XML structure but it's especially convenient to extract text values from tags. One can get, for example, a base64-encoded image - just walk down the VFS to the tag's directory and copy its text file to a real file. The VFS was inspired by a FUSE xmlfs: https://github.com/halhen/xmlfs AUTHOR Oleg Broytman <phd(a)phdru.name> COPYRIGHT Copyright (C) 2013 PhiloSoft Design LICENSE GPL Oleg. -- Oleg Broytman http://phdru.name/ phd(a)phdru.name Programmers don't die, they just GOSUB without RETURN.

by Larry Hastings Nov. 24, 2013

Nov. 24, 2013

On behalf of the Python development team, it's my privilege to announce the first beta release of Python 3.4. This is a preview release, and its use is not recommended for production settings. Python 3.4 includes a range of improvements of the 3.x series, including hundreds of small improvements and bug fixes. Major new features and changes in the 3.4 release series include: * PEP 435, a standardized "enum" module * PEP 436, a build enhancement that will help generate introspection information for builtins * PEP 442, improved semantics for object finalization * PEP 443, adding single-dispatch generic functions to the standard library * PEP 445, a new C API for implementing custom memory allocators * PEP 446, changing file descriptors to not be inherited by default in subprocesses * PEP 450, a new "statistics" module * PEP 453, a bundled installer for the *pip* package manager * PEP 456, a new hash algorithm for Python strings and binary data * PEP 3154, a new and improved protocol for pickled objects * PEP 3156, a new "asyncio" module, a new framework for asynchronous I/O Python 3.4 is now in "feature freeze", meaning that no new features will be added. The final release is projected for late February 2014. To download Python 3.4.0b1 visit: http://www.python.org/download/releases/3.4.0/ Please consider trying Python 3.4.0b1 with your code and reporting any new issues you notice to: http://bugs.python.org/ Enjoy! -- Larry Hastings, Release Manager larry at hastings.org (on behalf of the entire python-dev team and 3.4's contributors)

[ANN] PyDitz version 0.2
by Glenn Hutchings Nov. 23, 2013

Nov. 23, 2013

Announcing version 0.2 of PyDitz, a drop-in replacement for Ditz, a distributed bug tracker. Changes in this version: * Fixed problem with blank comments in a few commands. Features: * Whereas Ditz, when typed on its own, runs the "todo" command, PyDitz drops you into a command shell where you can run Ditz commands and get completion on command names, issue names and release names according to context. * It keeps an intelligent cache of issues, so parsing of all the YAML files isn't necessary for each command. This greatly improves speed when you have lots of issues. * With PyDitz, you don't have to run it from the same directory where the issue database is; it will look in parent directories for it. * You can use the database engine of PyDitz in Python programs to migrate bug databases to and from Ditz format, or create summary reports in your own favourite format. In this release, all the Ditz commands are implemented except "edit", "html" and "validate". They're planned for some time Real Soon Now. You can get PyDitz from: https://pypi.python.org/pypi/pyditz or browse the sources at: https://bitbucket.org/zondo/pyditz It's distributed under the GPL v2+.

ANN: psutil 1.2.0 released
by Giampaolo Rodola' Nov. 20, 2013

It supports Linux, Windows, OSX, FreeBSD and Solaris with Python versions from 2.4 to 3.4. === New features === psutil provides a new wait_procs() utility function which waits for multiple processes to terminate ( https://code.google.com/p/psutil/issues/detail?id=440) Tipical use case is: 1. send SIGTERM to a list of processes 2. give them some time to terminate 3. send SIGKILL to those ones which are still alive Example: >>> def on_terminate(proc): ... print("process {} terminated".format(proc)) ... >>> for p in procs: ... p.terminate() ... >>> gone, still_alive = psutil.wait_procs(procs, timeout=3, callback=on_terminate) >>> for p in still_alive: ... p.kill() ... >>> Also, you can now avoid to pass a PID to psutil.Process constructor in which case os.getpid() will be assumed. === Main bugfixes === High priority issue https://code.google.com/p/psutil/issues/detail?id=348on Windows XP has been fixed. === Links === * Home page: http://code.google.com/p/psutil * Downloads: https://pypi.python.org/pypi?:action=display&name=psutil#downloads * API Reference: http://code.google.com/p/psutil/wiki/Documentation Please try out this new release and let me know if you experience any problem by filing issues on the bug tracker.

ANN: Bokeh 0.3 released
by Bryan Van de Ven Nov. 20, 2013

Nov. 20, 2013

All, I am pleased to announce the release of Bokeh 0.3! Bokeh is a Python interactive visualization library for large datasets that natively uses the latest web technologies. Its goal is to provide elegant, concise construction of novel graphics in the style of Protovis/D3, while delivering high-performance interactivity over large data to thin clients. If you are using Anaconda, you can install through conda: conda install bokeh Alternatively you can install from PyPI using pip: pip install bokeh This release was largely an internal refactor to merge the BokehJS and Bokeh projects into one repository, and to greatly improve and simplify the BokehJS coffee script build process. Additionally, this release also includes a number of bug and stability fixes, and some enhancements, including: * bugfixes: - #155 ColumnDataSource does not update column_names - #150 If you plot circles that all have a position (0,0), there is a crash - #117 axis_line_color=None does not work * enhancements: - #157 xaxis, etc should return collection object - #129 The sampledata download is confusing - #82 Improve hold() functionality in notebook See the CHANGELOG for full details. Several new examples were added including a reproduction of Burtin's Antibiotics, and examples of animation using the Bokeh plot server. ColorBrewer palettes were also added on the python side. Finally, the user guide has been flushed out and will continually be updated as features and API changes are made. Check out the full documentation and interactive gallery at http://bokeh.pydata.org The release of Bokeh 0.4 is planned for early January. Some notable features to be included are: * Integrate Abstract Rendering into bokeh server * Better grid-based layout system; use Cassowary.js for layout solver * Tool Improvements (pan always on, box zoom always on, passive resize with hot corners) * Basic MPL compatibility interface (enough to make ggplot.py work) * Expose image plot in Python interface: Add BSON for sending large data Issues or enhancement requests can be logged on the Bokeh Github page: https://github.com/continuumio/bokeh Questions can be directed to the Bokeh mailing list: bokeh(a)continuum.io Regards, Bryan Van de Ven
