cx_OracleTools 8.0
by Anthony Tuininga 10 Sep '10

10 Sep '10

What is cx_OracleTools? cx_OracleTools is a set of Python scripts that handle Oracle database development tasks in a cross platform manner and improve (in my opinion) on the tools that are available by default in an Oracle client installation. Those who use cx_Oracle may also be interested in this project, if only as sample code. Binaries for Windows and Linux are provided for those who do not have a Python installation. Where do I get it? http://cx-oracletools.sourceforge.net What's new? 1) In DescribeObject, added option --show-synonyms which enables display of synonyms that reference the object. The default value for this option is false. 2) In DescribeObject, DescribeSchema, ExportObjects and RebuildTable, added support for Oracle context objects. 3) In DescribeSchema, ExportObjects and RecompileSource, added option --name-file which acts in the same fashion as the --name option except that the value of the option refers to a file containing a list of names, one name per line. 4) In DescribeObject, DescribeSchema and ExportObjects, added option --include-view-columns which enables specification of the column names when creating a view. 5) In DescribeObject and DescribeSchema added support for eliminating the quotas on tablespaces when generating create user statements. 6) In DescribeObject, DescribeSchema and ExportObjects, added options --as-of-timestamp and --as-of-scn which enable flashback queries when performing describes. This can be very useful for recovering those accidentally issued DDL commands! 7) In DumpCSV, make use of the builtin module csv and the standard option --schema; in addition, allow the file name to be specified as "-" or not at all in which case the output goes to stdout. 8) In DumpData, added support for dumping CLOB, BLOB and binary data values correctly. A commit statement is also appended to the output now as a convenience. 9) In ExportXML, added option --sort-by which allows the result set to be sorted before exporting. In addition, the source can be a query instead of simply a table name. 10) In GeneratePatch, switch to the new more intelligent parser. 11) In ImportXML, now use cElementTree rather than home-grown XML processing library. 12) In RebuildTable, removed SQL*Plus specific statements since by default connect statements are issued which only works properly with PatchDB. 13) In RecompileSource, added option --connect-as-owner and removed option --password. The new option specifies that when invalid objects are recompiled that a connection to the owner of the invalid object is established using the password of the current connection. The default value is false since this is an uncommon situation and is retained at all for support of product development at Computronix. 14) Replaced CompileSource with PatchDB which uses a much more advanced parser and is setup to handle additional commands besides executing SQL scripts. 15) Added setup.py for building with cx_Freeze which means that MSI packages for Windows and RPM packages for Linux are now available. 16) Other changes required to keep up with changes in Python, dependent libraries and Oracle (including up to Oracle 11.2) Anthony Tuininga

Issue 1 of "PET: English Translation" a Python magazine is out!
by Roberto Alsina 09 Sep '10

09 Sep '10

This magazine is a community effort. It's done by Python guys in Argentina. We are quite proud of it, and we hope you like it too. You can read Issue 1 in our webpage: http://revista.python.org.ar/1/html-en/ It's available in several different formats, including PDF, ePub, Mobipocket, HTML and FB2, and is released under a CC-by-nc-sa license. It has been translated to english by us, and we are not native speakers. Hopefully Shakespeare will not raise from his grave to slap us for grievous offense against his language! But, to save us from the Wrath of Wil, feel free to point out any mistakes and unhappy turns of phrase in the comments. Now that we have the english version out, we have *much bigger* plans for our second issue. We'll keep you posted.

(Webinar) Connecting the Dots: US SEC, ABS Mandates, Financial Modeling and Python
by Kendra Penrose 07 Sep '10

07 Sep '10

Connecting the Dots: US SEC, ABS Mandates, Financial Modeling and Python Date: Wednesday September 22, 2010 Time: 10:00am PST/1:00pm EST/ 17:00 UTC Space is limited so register now at https://www1.gotomeeting.com/register/151429928 Join us for a webinar co-hosted by Ann Rutledge, R&R Consulting, and Diane Mueller, ActiveState, focused on the recent US SEC regulation, ABS Mandates, Financial Modeling and Python. Recently, the US SEC published a proposal (33-9117) covering a series of new initiatives to address the current lack of transparency of asset-backed securities (ABS). This new series of SEC proposed initiatives are a way of putting "teeth" into Reg AB that would give the SEC (and the market) enough data to police and prevent events like the recent subprime crisis. In this webinar, Ann Rutledge and Diane Mueller will discuss a new key technical requirement in the SEC proposal; the provision of a Python computer program and the market data required to properly monitor and analyse these complex ABS transactions. The role of the proposed program is to enable the capture of all the complicated terms of an ABS deal in code that can be used to analyze the cash flows in each deal and how the returns will get split up between different parties. Currently, investors, fund managers, and investment managers receive a complex, textual description of this information in the prospectus, which makes it difficult to perform or visualize a rigorous quantitative or if-then analysis of the asset-backed securities. By attending this webinar you will learn: * some historical challenges regarding regulation of the asset-backed securities (ABS) market * technical benefits of Python and XML for capturing essential financial information in ABS transactions * about opportunities for collaboration between between regulators, accounting standards bodies, and the open source software community If you are in the finance industry and are affected by the new SEC regulations, you don't want to miss this webinar!
