08 Dec '11

Announcing Speedometer 2.8 -------------------------- Speedometer home page: http://excess.org/speedometer/ Download: http://excess.org/speedometer/speedometer-2.8.tar.gz New in this release: ==================== - Added a linear scale option: -l. Best used in combination with -m (and possibly -n) to customize the range to be displayed. Thanks to jukie.net for sponsoring this feature. - Replace silly "curved" reading with a weighted moving average - New option to display all values in bits per second: -s - New options to set minimum (-n) and maximum (-m) values displayed on the graphs in bytes/s. Defaults are -n 32 and -m 2**32 - Accept shortened versions of -rx and -tx: -r and -t My intent is to drop use of the original forms in 3.0 and add --long-versions of all options - Use IEC notation of sizes MiB, GiB etc. - Install script as both speedometer.py and speedometer About Speedometer ================= Speedometer is a console bandwidth and file download progress monitor with a linear/logarithmic bandwidth display and a simple command-line interface. Speedometer requires Urwid for full-console bar graph display. Urwid may be downloaded from: http://excess.org/urwid/ Speedometer is released under the GNU LGPL.

by Jimmy Retzlaff 08 Dec '11

08 Dec '11

What is mrjob? ----------------------- mrjob is a Python package that helps you write and run Hadoop Streaming jobs. mrjob fully supports Amazon's Elastic MapReduce (EMR) service, which allows you to buy time on a Hadoop cluster on an hourly basis. It also works with your own Hadoop cluster. Some important features: * Run jobs on EMR, your own Hadoop cluster, or locally (for testing). * Write multi-step jobs (one map-reduce step feeds into the next) * Duplicate your production environment inside Hadoop * Upload your source tree and put it in your job's $PYTHONPATH * Run make and other setup scripts * Set environment variables (e.g. $TZ) * Easily install python packages from tarballs (EMR only) * Setup handled transparently by mrjob.conf config file * Automatically interpret error logs from EMR * SSH tunnel to hadoop job tracker on EMR * Minimal setup * To run on EMR, set $AWS_ACCESS_KEY_ID and $AWS_SECRET_ACCESS_KEY * To run on your Hadoop cluster, install simplejson and make sure $HADOOP_HOME is set. More info: * Install mrjob: pip install mrjob -OR- easy_install mrjob * Documentation: http://packages.python.org/mrjob/ * PyPI: http://pypi.python.org/pypi/mrjob * Mailing list: http://groups.google.com/group/mrjob * Development is hosted at github: http://github.com/Yelp/mrjob What's new? -------------------- mrjob v0.3.0 is a major new release.

ANN: Python Tools for Visual Studio 1.1 Beta 1
by Dino Viehland 07 Dec '11

07 Dec '11

We're pleased to announce the release of Python Tools for Visual Studio 1.1 Beta ( http://pytools.codeplex.com/releases/view/76089 ). Python Tools for Visual Studio (PTVS) is an open-source plug-in for Visual Studio which supports programming with the Python programming language. This release includes new core IDE features, a couple of new sample libraries for interacting with Kinect and Excel, and many bug fixes for issues reported since the release of 1.0. Since the last alpha release we've fixed over 30 bugs and implemented several features around the project system and references. For IronPython users you can now add references to .NET projects or .NET assemblies and we'll automatically reload and re-analyze the references when they're rebuilt. For CPython users you can now add a reference to a .pyd extension module and we'll analyze the extension module and provide completions. We've also improved intellisense across multiple Python projects in the same solution. Finally we've added support for using IPython mode w/o PyLab - this enables out-of-line graphs and improves the startup time of the interactive window. We've also added many new features which improve the basic editing experience which were also available during 1.1 Alpha. This includes a feature for automatically adding imports after typing an identifier, a command for cleaning up unused imports, support for recognizing isinstance() calls and using them for providing improved completions, and using goto definition to go to members defined in the standard library. We've also made improvements to the project system so it'll behave more like the C# including proper support of linked files outside of the project directory. And we've made some improvements to our IPython REPL support including support for inline graphs and proper support for IPython's numbered prompts. Finally we've made several small improvements to the debugger including the option to step into the Python standard library while debugging, the option to not break on SystemExit exception with exit codes of zero as well as displaying the Python thread name in the threads window. Altogether this release includes over 130 features and bug fixes since 1.0 - a complete list of the changes is available here: http://bit.ly/IpyTools11Beta1Fixes Another major addition to 1.1 includes the addition of two additional sample libraries available as separate downloads: PyKinect for working with the Kinect Beta SDK and Pyvot for working with Excel spreadsheets. Once downloaded and installed these plug-in to Visual Studio and provide templates; and they provide built-in support for installing into one of the recognized Python interpreters via Tools->Python Tools->Samples. The PyKinect sample is a wrapper around the Kinect SDK and enables development with the Kinect SDK directly from Python. The library presents an API which is similar to the API exposed via the Kinect SDK for C# developers. The sample includes a new template for quickly getting started creating games using PyGame with PyKinect. PyKinect is licensed under a license similar to the existing Kinect SDK. Pyvot (pronounced Pivot) connects familiar data-exploration and visualization tools in Excel with the powerful data analysis and transformation capabilities of Python, with an emphasis on tabular data. It provides a simple and Pythonic interface to Excel, smoothing over the pain points in using the existing Excel object model as exposed via COM. We'd like to thank all of the users who took the time to report issues and feedback for this release: 445363200, Andrew, AphexSA, benpmorgan, chadbr, dgkbny, drgn, holmboe, hyh, jimpeak, juanalumni, lblanchon, liuzhenhai, mahpour, MichaelBaker, po6856, pztrick44, salerio, slide_o_mix, somini, SoonStudios, stakemura, sumitbasu, swift_dev, synergetic, teebot, timeisaparallax, tonyandrewmeyer, xavier_grundus, and Zooba.

[ANNOUNCE] pypiserver 0.5.0 - minimal pypi server
by Ralf Schmitt 05 Dec '11

05 Dec '11

Hi, I've just uploaded pypiserver 0.5.0 to the python package index. pypiserver is a minimal PyPI compatible server. It can be used to serve a set of packages and eggs to easy_install or pip. pypiserver is easy to install (i.e. just easy_install pypiserver). It doesn't have any external dependencies. http://pypi.python.org/pypi/pypiserver/ should contain enough information to easily get you started running your own PyPI server in a few minutes. The code is available on github: https://github.com/schmir/pypiserver Changes in version 0.5.0 ------------------------- - make setup.py install without calling 2to3 by changing source code to be compatible with both python 2 and python 3. We now ship a slightly patched version of bottle. The upcoming bottle 0.11 also contains these changes. - make the single-file pypi-server-standalone.py work with python 3 -- Cheers, Ralf
