by Brad Allen July 12, 2011

July 12, 2011

PyTexas 2011 will take place this year in College Station at Texas A&M University on Sept 10-11, where Python has become an important part of the curriculum and enjoys strong faculty support and student interest. http://pytexas.org/PyTexas2011 We're planning for about 100-150 attendees, after last years enthusiastic response of 94 attendees. This year expectations are high for growing PyTexas into a bigger, better conference. As a sponsor you can help us reach those expectations through your financial contribution, prize donations, and even by showing up with your booth (space is limited, so reserve your booth space soon!). So please consider sponsoring PyTexas 2011 though a financial contribution to the Python Software Foundation (PSF): http://pytexas.org/Sponsorship2011

mrjob v0.2.7 released
by Jimmy Retzlaff July 12, 2011

July 12, 2011

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: python setup.py install * Documentation: http://packages.python.org/mrjob/ * PyPI: http://pypi.python.org/pypi/mrjob * Development is hosted at github: http://github.com/Yelp/mrjob What's new? ------------- Big thank you to Yelp intern Steve Johnson, who wrote the majority of the code for this release. Wahbeh Qardaji, another Yelp intern, contributed as well, and has been working hard on features for v0.3.0. v0.2.7, 2011-07-12 -- Hooray for interns! * All runner options can be set from the command line (Issue #121) * Including for mrjob.tools.emr.create_job_flow (Issue #142) * New EMR options: * availability_zone (Issue #72) * bootstrap_actions (Issue #69) * enable_emr_debugging (Issue #133) * Read counters from EMR log files (Issue #134) * Clean old files out of S3 with mrjob.tools.emr.s3_tmpwatch (Issue #9) * EMR parses and reports job failure due to steps timing out (Issue #15) * EMR boostrap files are no longer made public on S3 (Issue #70) * mrjob.tools.emr.terminate_idle_job_flows handles custom hadoop streaming jars correctly (Issue #116) * LocalMRJobRunner separates out counters by step (Issue #28) * bootstrap_python_packages works regardless of tarball name (Issue #49) * mrjob always creates temp buckets in the correct AWS region (Issue #64) * Catch abuse of __main__ in jobs (Issue #78) * Added mr_travelling_salesman example

PyModel-0.9: Model-based testing in Python
by Jon Jacky July 12, 2011

July 12, 2011

PyModel-0.9, an open-source model-based testing framework in Python, has been released. Code, documents, and downloads are available: http://staff.washington.edu/jon/pymodel/www/ http://pypi.python.org/pypi/PyModel https://github.com/jon-jacky/PyModel Version 0.9 adds new functionality, new samples, and some changes to internals to be more consistent with recommended Python style and programming practices. For details see see pymodel/notes/release-0.9.txt at the above site. Version 0.85 was announced here in March 2010. There will be talk on PyModel at SciPy 2011 on Wednesday, July 13 in Austin, Texas: http://conference.scipy.org/scipy2011/ ------- In unit testing, the programmer codes the test cases, and also codes assertions that check whether each test case passed. In model-based testing, the programmer codes a "model" that generates as many test cases as desired and also acts as the oracle that checks the cases. PyModel supports on-the-fly testing, which can generate indefinitely long nonrepeating tests as the test run executes. PyModel can focus test cases on scenarios of interest by composition, a versatile technique that combines models by synchronizing shared actions and interleaving unshared actions. PyModel can guide test coverage according to programmable strategies coded by the programmer. PyModel provides three programs: - pma, pymodel analyzer: generates a finite state machine (FSM) and computes properties by exploring a model program, FSM, test suite, or a product of these. - pmg, pymodel graphics: generates a file of graphic commands from an FSM. - pmt, pymodel tester: displays traces, generates tests offline, executes offline tests, or generates and executes tests on-the-fly. Use pma and pmg to visualize and preview the behavior of pmt. Every path through the graph created by pma (and drawn by pmg) is a trace (test run) that may be generated by pmt, when pma and pmt are invoked with the same arguments.
