[ANN] PyTables 2.0rc1 released
by Ivan Vilata i Balaguer 26 Apr '07

26 Apr '07

Hi all, The development of the second major release of PyTables is steadily approaching its goal! Today we want to announce the *first release candidate version of PyTables 2.0*, i.e. PyTables 2.0rc1. This version settles the API and file format for the following PyTables 2.0 series. No more features will be added until the final version of 2.0 is released, so we do enter a time for exhaustive platform testing and fixing the last remaining bugs, as well as updating any outdated documentation. Your collaboration is very important in this stage of development, so we encourage you to download PyTables, test it, and report any problems you find or any suggestions you have. Thank you! And now, the official announcement: ============================ Announcing PyTables 2.0rc1 ============================ PyTables is a library for managing hierarchical datasets and designed to efficiently cope with extremely large amounts of data with support for full 64-bit file addressing. PyTables runs on top of the HDF5 library and NumPy package for achieving maximum throughput and convenient use. The PyTables development team is happy to announce the public availability of the second *beta* version of PyTables 2.0. This will hopefully be the last beta version of 2.0 series, so we need your feedback if you want your issues to be solved before 2.0 final is out. You can download a source package of the version 2.0rc1 with generated PDF and HTML docs and binaries for Windows from http://www.pytables.org/download/preliminary/ For an on-line version of the manual, visit: http://www.pytables.org/docs/manual-2.0rc1 Please have in mind that some sections in the manual can be obsolete (specially the "Optimization tips" chapter). Other chapters should be fairly up-to-date though (although still a bit in state of flux). In case you want to know more in detail what has changed in this version, have a look at ``RELEASE_NOTES.txt``. Find the HTML version for this document at: http://www.pytables.org/moin/ReleaseNotes/Release_2.0rc1 If you are a user of PyTables 1.x, probably it is worth for you to look at ``MIGRATING_TO_2.x.txt`` file where you will find directions on how to migrate your existing PyTables 1.x apps to the 2.0 version. You can find an HTML version of this document at http://www.pytables.org/moin/ReleaseNotes/Migrating_To_2.x Keep reading for an overview of the most prominent improvements in PyTables 2.0 series. New features of PyTables 2.0 ============================ - NumPy is finally at the core! That means that PyTables no longer needs numarray in order to operate, although it continues to be supported (as well as Numeric). This also means that you should be able to run PyTables in scenarios combining Python 2.5 and 64-bit platforms (these are a source of problems with numarray/Numeric because they don't support this combination as of this writing). - Most of the operations in PyTables have experimented noticeable speed-ups (sometimes up to 2x, like in regular Python table selections). This is a consequence of both using NumPy internally and a considerable effort in terms of refactorization and optimization of the new code. - Combined conditions are finally supported for in-kernel selections. So, now it is possible to perform complex selections like:: result = [ row['var3'] for row in table.where('(var2 < 20) | (var1 == "sas")') ] or:: complex_cond = '((%s <= col5) & (col2 <= %s)) ' \ '| (sqrt(col1 + 3.1*col2 + col3*col4) > 3)' result = [ row['var3'] for row in table.where(complex_cond % (inf, sup)) ] and run them at full C-speed (or perhaps more, due to the cache-tuned computing kernel of Numexpr, which has been integrated into PyTables). - Now, it is possible to get fields of the ``Row`` iterator by specifying their position, or even ranges of positions (extended slicing is supported). For example, you can do:: result = [ row[4] for row in table # fetch field #4 if row[1] < 20 ] result = [ row[:] for row in table # fetch all fields if row['var2'] < 20 ] result = [ row[1::2] for row in # fetch odd fields table.iterrows(2, 3000, 3) ] in addition to the classical:: result = [row['var3'] for row in table.where('var2 < 20')] - ``Row`` has received a new method called ``fetch_all_fields()`` in order to easily retrieve all the fields of a row in situations like:: [row.fetch_all_fields() for row in table.where('column1 < 0.3')] The difference between ``row[:]`` and ``row.fetch_all_fields()`` is that the former will return all the fields as a tuple, while the latter will return the fields in a NumPy void type and should be faster. Choose whatever fits better to your needs. - Now, all data that is read from disk is converted, if necessary, to the native byteorder of the hosting machine (before, this only happened with ``Table`` objects). This should help to accelerate applications that have to do computations with data generated in platforms with a byteorder different than the user machine. - The modification of values in ``*Array`` objects (through __setitem__) now doesn't make a copy of the value in the case that the shape of the value passed is the same as the slice to be overwritten. This results in considerable memory savings when you are modifying disk objects with big array values. - All leaf constructors (except for ``Array``) have received a new ``chunkshape`` argument that lets the user explicitly select the chunksizes for the underlying HDF5 datasets (only for advanced users). - All leaf constructors have received a new parameter called ``byteorder`` that lets the user specify the byteorder of their data *on disk*. This effectively allows to create datasets in other byteorders than the native platform. - Native HDF5 datasets with ``H5T_ARRAY`` datatypes are fully supported for reading now. - The test suites for the different packages are installed now, so you don't need a copy of the PyTables sources to run the tests. Besides, you can run the test suite from the Python console by using:: >>> tables.tests() Resources ========= Go to the PyTables web site for more details: http://www.pytables.org About the HDF5 library: http://hdf.ncsa.uiuc.edu/HDF5/ About NumPy: http://numpy.scipy.org/ To know more about the company behind the development of PyTables, see: http://www.carabos.com/ Acknowledgments =============== Thanks to many users who provided feature improvements, patches, bug reports, support and suggestions. See the ``THANKS`` file in the distribution package for a (incomplete) list of contributors. Many thanks also to SourceForge who have helped to make and distribute this package! And last, but not least thanks a lot to the HDF5 and NumPy (and numarray!) makers. Without them PyTables simply would not exist.

EuroPython 2007 - call for refereed papers
by arigo＠tunes.org 24 Apr '07

24 Apr '07

Hi all, He're a reminder to submit a talk at EuroPython! Like each year, we have both the regular conference (see call at http://indico.cern.ch/conferenceCFA.py?confId=13919) and a somewhat separated Refereed Papers section. Here is the call for the latter. The deadline for both is the 18th of May. ======================================================================== EuroPython 2007 Vilnius, Lithuania 9-11 July Call for Refereed Papers http://www.europython.org/ ======================================================================== EuroPython is the only conference in the Python world that has a properly prestigious peer-reviewed forum for presenting technical and scientific papers. Such papers, with advanced and highly innovative contents, can equally well stem from academic research or industrial research. We think this is an important function for EuroPython, so we are even making some grants available to help people with travel costs. We will be happy to consider papers in subject areas including, but not necessarily limited to, the following: * Python language and implementations * Python modules (in the broadest sense) * Python extensions * Interoperation between Python and other languages / subsystems * Scientific applications of Python * Python in Education * Games * Agile Methodologies and Testing * Social Skills We are looking for Python-related scientific and technical papers of advanced, highly innovative content that present the results of original research (be it of the academic or "industrial research" kind), with proper attention to "state of the art" and previous relevant literature/results (whether such relevant previous literature is itself directly related to Python or not). We do not intend to let the specific subject area block a paper's acceptance, as long as the paper satisfies other requirements: innovative, Python-related, reflecting original research, with proper attention to previous literature. Abstracts ========= Please submit abstracts of no more than 200 words to the refereeing committee. You can send submissions no later than 18 May 2007. We shall inform you whether your paper has been selected and announce the conference schedule on the 25 May 2007. For all details regarding the submission of abstracts, please see the EuroPython website (http://www.europython.org). WARNING: Independently of their topic, all abstracts must be submitted *in the Refereed Papers track* in order to be considered by the refereeing committee! If your abstract is accepted, you must submit your corresponding paper before 29 June 2006. Last-minute changes will be accepted until the start of the conference. You should submit the paper as a PDF file, in A4 format, complete, "stand-alone", and readable on any standards-compliant PDF reader (basically, the paper must include all fonts and figures it uses, rather than using external pointers to them; by default, most PDF-preparation programs typically produce such valid "stand-alone" PDF documents). There are no strict typesetting rules. Refereeing ========== The refereeing committee, selected by Armin Rigo, will examine all abstracts and papers. The committee may consult external experts as it deems fit. Referees may suggest or require certain changes and editing in submissions, and make acceptance conditional on such changes being performed. We expect all papers to reflect the abstract as approved and reserve the right, at our discretion, to reject a paper, despite having accepted the corresponding abstract, if the paper does not substantially correspond to the approved abstract. Presentation ============ The paper must be presented at EuroPython by one or more of the authors. Presentation time will be between half an hour and an hour, including time for questions and answers, depending on each paper's details, and also on the total number of talks approved for presentation. Proceedings =========== We will publish the conference's proceedings in purely electronic form. By presenting a paper, authors agree to give the EuroPython conference non-exclusive rights to publish the paper in electronic forms (including, but not limited to, partial and total publication on web sites and/or such media as CDROM and DVD-ROM), and warrant that the papers are not infringing on the rights of any third parties. Authors retain all other intellectual property rights on their submitted abstracts and papers excepting only this non-exclusive license. Subsidised travel ================= We have funds available to subsidise travel costs for some presenters who would otherwise not be able to attend EuroPython. When submitting your abstract, please indicate if you would need such a subsidy as a precondition of being able to come and present your paper. (Yes, this possibility does exist even if you are coming from outside of Europe. Papers from people in New Zealand who can only come if their travel is subsidised, for example, would be just fine with us...). -+- Armin Rigo

ANN: Python IDE PyScripter version 1.8.5 released
by PyScripter 24 Apr '07

24 Apr '07

PyScripter is a free and open-source Python Integrated Development Environment (IDE) created with the ambition to become competitive in functionality with commercial Windows-based IDEs available for other languages. Being built in a compiled language is rather snappier than some of the other Python IDEs and provides an extensive blend of features that make it a productive Python development environment. PyScripter (1.8.5 - unofficial release) is now available at http://pyscripter.googlepages.com/. The main improvements compared to the last official release are: - Remote interpreter and debugging - Windows Vista compatibility - Easier use with moveable (unregistered) Python installations There are tens of other new features and bug fixes. See the full history for more information. Please note that to use remote debugging you need to download and install the Python package Rpyc (http://rpyc.sf.net) version 2.6 available for download at http://sourceforge.net/project/showfiles.php?group_id=155578. However this is optional and you can still use PyScripter as you did with earlier versions. For more information have a look at the following pages (the first one is essential reading): * Remote Interpreter and Debugger (http:// pyscripter.googlepages.com/remotepythonengines) * Using matplotlib with PyScripter (http:// pyscripter.googlepages.com/matplotlib) * Debugging django applications with PyScripter (http:// pyscripter.googlepages.com/django) * Using PyScripter with Portable Python (http:// pyscripter.googlepages.com/portablepython)

[ANN] pyx12-1.3.0 released
by John Holland 23 Apr '07

23 Apr '07

pyx12-1.3.0 is available at http://pyx12.sourceforge.net/ What is Pyx12? ============== Pyx12 is a HIPAA X12 document validator and converter. X12 files are a form of electronic data interchange. The HIPAA transaction standard requires certain types of healthcare data to be transmitted in this form. Pyx12 parses an ANSI X12N (Healthcare) data file and validates it against a representation of the Implementation Guidelines for a HIPAA transaction. By default, it creates a 997 response. It can also create an annotated HTML representation of the X12 document or can translate to and from several XML representations of the data file. What's New: =========== The map structure has been normalized, resulting in an approximate 25% performance increase. Unit tests and fixes for all reported bugs: Segment counting bug for LS/LE loops 834/LUI segment matching 997 ISA segment Removed "valid code" restriction from 837/2300/HI (Condition Codes) Invalid loop counting error with multiple GS loops Date validation - Dates prior to 1/1/1800 are now considered invalid. Improve 997 generation - better ISA, GS, and ST loop handling. Added new Claim Adjustment Reason Codes (code source 139). Fix 278 loop structure. More unit and functional tests. License =========== pyx12 is released under the BSD license. =========== John Holland Kalamazoo Community Mental Health and Substance Abuse Services jholland(a)kazoocmh.org

[ANNOUNCE] pyswarm 0.7.0 released - MDD for Python & PostgreSQL
by Anastasios Hatzis 23 Apr '07

23 Apr '07

pyswarm 0.7.0 released - MDD for Python & PostgreSQL Generated Scripts for Installation of Python Packages and PostgreSQL Databases 23 APRIL 2007: pyswarm 0.7.0 is the "Young Pickerl" mile-stone release of pyswarm. One of the goals for this prototype was to proof by a few features, that model-driven software development isn't only limited to improvements of the creation of Python applications, but can automatize even the deployment of such generated Python packages and the PostgreSQL databases. Please visit http://pyswarm.sourceforge.net/ for downloads or detail information. Version 0.7.0 uses a given UML model to create distutils-based setup artefacts that allow the quick and easy installation of the generated Python packages. Since pyswarm is still a prototype under heavy development, the applied Python setup procedure does not support the distribution over multiple nodes yet, so the entire application is installed as a single Python site-package on the local host. Each custom application also contains a Python script (initdb.py) that can be used to set-up the corresponding PostgreSQL databases of the application, either one single database, all databases on a particular host, or just all databases that are specified in the UML model. initdb.py is also capable to create corresponding login-roles or to drop and re-create databases, which should help developers to play quickly with new applications. In addition, 0.7.0 now encourages the consequent use of pyswarm naming conventions based on Python Style Guide (PEP #8) in the custom model and application domain. I have also fixed some bugs which I detected while working on the new features. The pyswarm documentation and the projects example directory have been updated and can be seperately downloaded from the project web-site. In order to test the SDK yourself download of the projects directory is strongly recommended. For detail information please read the CHANGES.txt coming with the distribution. This release is purposed for study only. It is not recommended to use for production environment. Anastasios Hatzis About pyswarm pyswarm is an active code-generator for model-driven development (MDD) of database-centric and n-tier server applications. Business logic is written entirely in Python and can be customized either in UML models or in complex Python method implementations, as elegant and powerful as code in Python can be. PostgreSQL is used as reliable database-server by the generated business logic components to store persistent entity objects. pyswarm is released under the GNU General Public License (GPL).
