PostgreSQL Global Development Group released updated versions which patch five security vulnerabilities

2008-01-07T08:35:00.000-08:00

Today the PostgreSQL Global Development Group is releasing updated
versions which patch five security vulnerabilities. These releases
update all current PostgreSQL versions, including 8.2, 8.1, 8.0, 7.4 and
7.3. They are considered CRITICAL and PostgreSQL DBAs and sysadmins
should install the update as soon as they reasonably can. Our security
team has made all efforts to make these patches backwards-compatible,
and upgrading does not require converting your data files.

Please read the remainder of this message for further important details
and announcements.

Details of Security Fixes
----------------------------
There are five security fixes included in this release. None of these
issues are known to have been exploited in the field; they were
discovered through security analysis.

Index Functions Privilege Escalation (CVE-2007-6600): as a unique
feature, PostgreSQL allows users to create indexes on the results of
user-defined functions, known as "expression indexes". This provided
two vulnerabilities to privilege escalation: (1) index functions were
executed as the superuser and not the table owner during VACUUM and
ANALYZE, and (2) that SET ROLE and SET SESSION AUTHORIZATION were
permitted within index functions. Both of these holes have now been
closed.

Regular Expression Denial-of-Service (CVE-2007-4772, CVE-2007-6067,
CVE-2007-4769): three separate issues in the regular expression
libraries used by PostgreSQL allowed malicious users to initiate a
denial-of-service by passing certain regular expressions in SQL queries.
First, users could create infinite loops using some specific regular
expressions. Second, certain complex regular expressions could consume
excessive amounts of memory. Third, out-of-range backref numbers could
be used to crash the backend. All of these issues have been patched.

DBLink Privilege Escalation (CVE-2007-6601): DBLink functions combined
with local trust or ident authentication could be used by a malicious
user to gain superuser privileges. This issue has been fixed, and does
not affect users who have not installed DBLink (an optional module), or
who are using password authentication for local access. This same
problem was addressed in the previous release cycle (see CVE-2007-3278),
but that patch failed to close all forms of the loophole.

EOL Notices
---------------------
Minor release 7.3.21 for PostgreSQL version 7.3 will be the last update
to the 7.3 branch. As version 7.3 is now over five years old, the
community will no longer release patches for it after today's release.
Users of version 7.3 are encouraged to upgrade to a more current version
as soon as possible, or to seek support from a commercial support vendor
who is willing to continue backpatching for them.

8.1.11 and 8.0.15 are also the last 8.1 and 8.0 update releases for
which the PostgreSQL community will produce binary packages for Windows.
Windows users are encouraged to move to 8.2.6 or later, since there are
Windows-specific fixes in 8.2 that are impractical to back-port. 8.1
and 8.0 updates will continue to be supported on other platforms and in
source form.

Download and Install
------------------------
PostgreSQL minor releases 8.2.6, 8.1.11, 8.0.15, 7.4.19 and 7.3.21 are
available through our FTP mirror network:

-- Source Code: http://www.postgresql.org/ftp/source/
-- Binaries for some platforms: http://www.postgresql.org/ftp/binary/

If you need additional information on the included updates, it's
available in the Release Notes
(http://www.postgresql.org/docs/current/static/release.html). These
upgrades can be copied directly over existing PostgreSQL binaries and do
not require dump-and-reload for any system which has been updated in the
last six months (older versions may require some specific post-update
steps; see the release notes).

As always, PostgreSQL update releases are cumulative. All security
fixes will be included in the upcoming version 8.3 release candidate.
This notice will be posted to the PostgreSQL security page:

pgAdmin III v1.8.1 released

2008-01-04T11:34:00.001-08:00

pgAdmin 1.8.1, the Open Source graphical PostgreSQL administration tool
for Windows, Linux, FreeBSD, Mac OS X and Solaris, now available for
download in source and a variety of binary formats from:

http://www.pgadmin.org/download/

v1.8.1 is primarily a bug fix release, including the following changes:

- Fix a bug that could cause a crash on GTK when closing the query tool
in certain circumstances.
- Avoid a crash if the connection is lost and the Functions node is
refreshed.
- Avoid crashes when working with objects with % characters in the
name.
- Properly reverse-engineer the SQL for indexes with DESC, NULLS FIRST
or NULLS LAST column options.
- Only offer the Jobs node if the user can access the pgagent schema.
- Ensure the 'Create Rule' context menu option is always offered when
appropriate.
- Prevent the user from trying to debug catalog objects.
- Refresh the tree without erroring after creating a new package on
EnterpriseDB.
- Fix a crash that occured if an object called '%' was selected in the
treeview, per Alexander Steffens.
- Fix a line number error in the debugger seen with procedures which
start on the same line as the 'CREATE PROCEDURE foo IS ...' Per report
from Heikki Linnakangas.
- Cleanup the covering index control logic in the Foreign Key dialogue.
- Fix to refresh version string and number, and last OID, per a report
from Alexander Kirpa.
- Disable CREATE FUNCTION etc. under EnterpriseDB packages because they
are created as part of the main package body.
- Fix some broken references to online help pages.
- Don't offer 'Drop Cascaded' unless the user can 'Drop' the object.
- Prevent non-superusers from attempting to use the debugger because the
plugin API won't let them anyway.
- Check that functions exist before debugging or setting global
breakpoints on them. Remove them from the treeview if not.
- Correct the URL for the EDB public synonym help page
- Handle the corner case when a user includes quotes in an object name
(backport of 2007-10-26 fix applied to trunk)
- Fix the debugger's connection class to ensure database names requiring
quotes will work and that is can be used with SSL and Kerberos
connections.
- Allow the length of array-typed columns to be changed (eg. 'character
varying[](100)'), per report from Ferenc Lutischan
- Don't allow the user to direct-debug trigger functions, only global
breakpoints should be used on them (or the trigger itself).
- Don't offer edbspl functions when creating triggers as they should
have inline bodies.
- Don't quote database names that happen to be keywords when starting
the debugger.
- Don't offer package names and system schemas as schemas when creating
public synonyms.
- Fix pgAgent's job query when a host agent is specified so that jobs
don't execute every time round the loop regardless of schedule, per
Brian Kalbfus.
- Add EnterpriseDB's default database (edb) to the Server dialog's
default option.
- Don't allow the user to debug an EnterpriseDB package function or
procedure if the body isn't defined.
- Don't offer the user the chance to create new columns on system
catalogues.
- Fix the debugger to send actual NULL values rather than 'NULL' through
the EnterpriseDB callable statement API. Allow parameter values to be
NULL or empty strings on both PostgreSQL and EnterpriseDB using the
same syntax as the Edit Grid.
- Always open the PostgreSQL Help when selecting that menu option, even
if connected to EnterpriseDB.
- Fix EnterpriseDB public synonym loading so that they aren't considered
system objects.
- Fix path discovery on Unix so standard installs can be relocated
easily.
- Fix character number display in the query tool.
- Use popen() when testing the versions of helper apps on non-windows
platforms to avoid an obscure bug on PPC Macs that could leave
wxExecute hanging indefinitely whilst waiting on a zombie process.
- When creating a new index and specifying both tablespace and fill
factor, make sure the SQL is formulated correctly, per Stefan Wolf
- Fix the locks tab on the server status dialogue so it works correctly
with PostgreSQL 8.3+.
- Properly format the object comments shown in the properties list when
a collection node is selected. Per report from Mike Blackwell.
- Fix a bug preventing the 'on error' flag of a pgAgent job step being
edited, per Jon Roberts.
- Properly escape _'s in queries for schemas, per Derek Fonda.
- Don't try to enable/disable prepared transaction related controls on
pre-8.1 servers, per Karl Zellnig

Viewalyzer 1.0.2 Released

2007-12-27T11:58:00.000-08:00

Viewalyzer is a graphical tool for recompiling Views and all dependent views. Also all Grants on all views will be available after recompiling. Before recompilation a backup will be made. When some unsolvable errors occur during recompilation everything will be “rolled back”. Also an errorlog is written to get informations what has happened. All your originally written DDL’s can be stored in the database and will that way be used during recompilation. You now can use “CREATE VIEW my_view AS SELECT * FROM my_table” and this will be used every time you recompile this view or one that my_view is dependent on.

New Features:

- Documentation available
- Compatibility with postgres 8.0 – 8.2
- Some minor bugs fixed

Download here: http://sourceforge.net/projects/viewalyzer/

PostgreSQL Maestro 7.12 released (8.3 support and more)

2007-12-14T09:25:00.000-08:00

SQL Maestro Group announces the release of PostgreSQL Maestro 7.12, a
powerful Windows GUI solution for PostgreSQL administration and database
development.

http://www.sqlmaestro.com/products/postgresql/maestro/

New features
=================

PostgreSQL 8.3 management extensions:

1. Support for ENUM types has been added. You can create new such types,
edit existing ones and, of course, drop unnecessary types. Also the
corresponding editor has been implemented in the Data Grid (also works for
domains based on ENUM types, domains based on domains based on ENUM types
and so on).

2. Function management: now it is possible to set up the environment for a
function as well as customize its execution cost and estimated number of
rows returned by a set-returning function.

3. Support for XML and UUID types has been implemented.

Other server management extensions:

1. The Rule permission is no longer displayed for PostgreSQL 8.2+ because it
was removed in that release for security reasons.

2. SQL parser now accepts queries with !~~, ~~, ~~* and !~~* operators (SQL
Formatter, View Editor).

Interface improvements:

1. The SQL Generator tool has been implemented. Use this feature to produce
various SQL scripts (CREATE, DROP, SELECT, INSERT, etc) for the selected
object. The result script can be saved to a file, copied to clipboard, and
opened in SQL Editor or SQL Script Editor.

2. Data Grid: the notification pane is now displayed after simple mode
activation (filtering, grouping and sorting features are not supported in
this mode). All the related settings can be customized in the Options
dialog.

3. Data Grid: the Generate Query command has been added to the Table / View
Editor. Use this command to copy current filter conditions to the SQL Editor
window as an SQL query. It is also possible to copy filter condition to
clipboard as WHERE clause using grid's popup menu.

4. Data Grid: now it is possible to encrypt the contents of the selected
cell by the md5 algorithm (the corresponding item has been added to grid's
popup menu).

5. Object editors, SQL Editor, Database Designer, BLOB Viewer and other
database-dependent windows: only connected databases are now displayed in
the drop-down list.

6. Some other minor improvements and corrections.

Full press release:

Resolver Systems announces the public Beta release of Resolver One: the first Spreadsheet/Python hybrid

2007-12-09T14:13:00.001-08:00

Resolver Systems (www.resolversystems.com) today announces the public Beta release of its groundbreaking program, Resolver One, a Rapid Application Development tool for analysing and presenting business data using a familiar spreadsheet interface. Resolver One integrates databases, code and IT-developed components to create powerful and easy-to-use solutions - all using your existing knowledge of spreadsheets. The power and ingenious flexibility of Resolver One comes from the fact that it is fully programmable with Python code. After the success of the private Beta subscription in September 2007 (more than 1,000 sign-ups), Resolver is now planning on an official v1.0 release as early as January 2008.

Today Resolver Systems announces the public beta of Resolver One, a revolutionary improvement in spreadsheet systems. In Resolver One, the spreadsheet is a computer program
“This will change the way businesses think about and use spreadsheets. So many of the problems of the traditional model – poor database integration, and the lack of auditing, iterative analysis, or web-publishing - are solved when you realize that any spreadsheet is, at heart, just a computer program,” said Giles Thomas, CTO and MD of Resolver Systems.

“With this launch,” said Jean Viry-Babel, Head of Sales, “we get the opportunity to get our product into the hands of the 1,000s of people who have expressed an interest since Resolver One was featured on Jon Udell’s blog and Slashdot.”

Resolver One uses the Python programming language which was first released in 1991. Python is an easily learnable and highly expressive language with a rich standard library; it has been successfully used in a wide variety of applications, in businesses and in academia. Its clean syntax allows newcomers to become productive rapidly, while its more sophisticated features and built-in test framework allow experienced developers to build powerful tools which can adapt quickly to changing requirements.

“We’re excited that at last people will be able to develop sophisticated applications, all within a familiar spreadsheet interface,” added Giles Thomas.

About Resolver Systems:

Resolver Systems was founded in 2005 to produce a next generation spreadsheet. The founders, Giles Thomas, Robert Smithson and Patrick Kemmis, had all struggled with the challenges of running multi-million or multi-billion dollar businesses through poorly debugged spreadsheets. Their solution – Resolver One – seamlessly integrates a powerful and flexible programming language and a traditional spreadsheet environment. Already Resolver One has received extensive interest from companies in the financial, medical and academic communities.

Whitebeam 1.1.5 released

2007-11-01T08:21:00.000-07:00

Whitebeam is an open source web-application server built on PostgreSQL for data storage and the Mozilla SpiderMonkey JavaScript engine for application logic.

Started in 2000 and released as open source in 2001, Whitebeam is a mature product that has been in commercial operation hosting real web applications for over 6 years. Examples of commercial applications :
http://www.whitebeam.org/community/users.rhtm

The latest release (1.1.5) follows several years of continuous development in both performance and functionality. JavaScript bindings are provided to the PostgreSQL database, LibGD for image manipulation, SMTP for email creation, HTTP for SOAP and XML/RPC like applications amongst others.

For those that don't want to write SQL, Whitebeam 'Templates' provide high-level functional abstractions. In addition the templates avoid any possibility of 'SQL injection' security issues common with other web development platforms. Examples of 'templated' functionality include hierarchical tree-like catalogues, session management, contact/membership management and data collections.

Full documentation is available on the Whitebeam web-site
http://www.whitebeam.org

Or from the SourceForge project page :
http://sourceforge.net/projects/whitebeam

Whitebeam runs as an Apache web-server module, either on Apache 1.3, 2.0 or 2.2.

Security fix for vulnerability in Django's internationalization framework.

2007-10-26T13:29:00.000-07:00

A fix has been released for a security vulnerability discovered in Django's internationalization framework. The complete details are below, but the executive summary is that you should updated to a fixed version of Django immediately.

You can download them at http://www.djangoproject.com/download/. Those tracking trunk development should "svn update" as soon as possible.

Description of vulnerability
A per-process cache used by Django's internationalization ("i18n") system to store the results of translation lookups for particular values of the HTTP Accept-Language header used the full value of that header as a key. An attacker could take advantage of this by sending repeated requests with extremely large strings in the Accept-Language header, potentially causing a denial of service by filling available memory.

Due to limitations imposed by web server software on the size of HTTP header fields, combined with reasonable limits on the number of requests which may be handled by a single server process over its lifetime, this vulnerability may be difficult to exploit. Additionally, it is only present when the "USE_I18N" setting in Django is "True". Nonetheless, all users of affected versions of Django will be encouraged to update.

Affected versions
Django trunk prior to revision [6608].
Django 0.96
Django 0.95 (including 0.95.1)
Django 0.91
Resolution
New versions of Django containing this fix have been released today which lter this caching mechanism to store shortened, normalized values and to reject improperly-formatted headers.

These versions are called:

Django 0.96.1 (replaces Django 0.96)
Django 0.95.2 (replaces Django 0.95.1)
Django 0.91.1 (replaces Django 0.91.1)
Anyone using a stable Django release should upgrade to one of these point releases immediately. These fixed versions have already been provided to maintainers of Django packages for various OS distributions and should be released shortly.

Anyone tracking Django's trunk development should use Subversion to update to at least revision [6608].

PostgreSQL 8.3 Beta 1 now ready for testing!

2007-10-09T10:22:00.000-07:00

The PostgreSQL Global Development Group released the long-awaited
first beta of version 8.3. Thanks to an unprecedented number of new
patches, this version introduces more new and improved features than any
previous one. Of course, more new features means that 8.3 needs more
user testing than any previous version, so we're counting on you to
download it and test it with development versions of your applications.

openSUSE 10.3 is Now Available

2007-10-04T07:29:00.000-07:00

Novell today announced the availability of openSUSE® 10.3, the newest version of the award-winning community Linux* distribution. Available for free download or in a convenient packaged retail edition, openSUSE 10.3 provides everything a user needs to get started with Linux. To improve the user experience, openSUSE 10.3 includes a flexible Linux-Windows dual-boot configuration, improved user interface, Microsoft* Office file compatibility with the latest OpenOffice.org office productivity suite, and enhanced multimedia support.

“The openSUSE community continues to deliver innovations and has created a new version of openSUSE that will excite a wide range of computer users,” said Andreas Jaeger, director of the openSUSE project. “OpenSUSE 10.3 provides a stable and state-of-the-art operating system based on Linux kernel 2.6.22, and it contains a large variety of the latest open source applications for desktops, servers and application development.”

Enhancements to openSUSE 10.3 include the newest versions of the GNOME* and KDE desktop environments, including a KDE 4 preview. OpenOffice.org 2.3 makes sharing files with Microsoft Office users easy, and the newest version of AppArmor™ protects the Linux operating system and applications from attacks, viruses and malicious applications. OpenSUSE 10.3 also now includes MP3 support out of the box for Banshee™ and Amarok, which are the default media players in openSUSE. In addition, openSUSE 10.3 offers the latest open source applications for developing applications, setting up a home network and running a Web server, as well as the latest virtualization software such as Xen* 3.1 and VirtualBox 1.5.

Version 10.3 makes openSUSE the first Linux distribution to take full advantage of the “1-Click Install” option, which gives openSUSE 10.3 users easy access to many more software packages residing on the openSUSE Build Service. Contributed by a single openSUSE community member, the one-click install is an example of the value openSUSE's strong community of developers, testers, writers, translators, artists and users bring to the distribution. OpenSUSE 10.3 was created by the openSUSE project, the community initiative sponsored by Novell that promotes the use of Linux everywhere. The openSUSE project has more than 54,000 registered members.

Availability and Pricing
OpenSUSE 10.3 is now available for free download at www.opensuse.org. The retail edition of openSUSE 10.3 is available on www.shopnovell.com as well as in select retail locations. It delivers the same packages as the downloadable version on an installable DVD for 32- and 64-bit architectures, and it is accompanied by a second DVD containing a large selection of additional software available at the release date. Also included are a comprehensive user manual and 90 days of installation support, all for a suggested $59.95.

Python: Myths about Indentation

2007-09-27T07:43:00.000-07:00

This is the place where to point your friends when they gripe about Python's "significant whitespace". There are even details on how it is parsed, for those who are interested.

http://www.secnetix.de/~olli/Python/block_indentation.hawk

The following is covered:
Whitespace is significant in Python source code.
Python forces me to use a certain indentation style.
You cannot safely mix tabs and spaces in Python.
I just don't like it.
How does the compiler parse the indentation?

SQL Injection Cheat Sheet

2007-09-19T08:42:00.001-07:00

What is SQL Injection? From wikipedia: SQL injection is a technique that exploits a security vulnerability occurring in the database layer of an application. The vulnerability is present when user input is either incorrectly filtered for string literal escape characters embedded in SQL statements or user input is not strongly typed and thereby unexpectedly executed

Here is a nice SQL injection cheat sheet. Currently only for MySQL and Microsoft SQL Server, some ORACLE and some PostgreSQL

Pydev 1.3.9 Released

2007-09-11T12:22:00.000-07:00

Python Development Environment (Python IDE plugin for Eclipse). Features editor, code completion, refactoring, outline view, debugger, and other goodies - check http://pydev.sf.net).

Pydev Release: 1.3.9
--------------------

Major highlights:
-----------------

* Fixed problem when configuring jython
* Patch from paulj: debbugger working with jython 2.2rc2
* Patch from Oskar Heck: debbugger can change globals
* Added action to delete all .pyc / $py.class files
* Added actions to add/remove the pydev configuration from a project (previously, the only way to add a nature was to open a python file within a project).
* Ctrl+Shift+O: When used with a selection will consider lines ending with \ (without selection organizes imports)
* Auto-add "import" string will not be added when adding a space in the case: from xxximport (just after from xxx)
* Templates created with tabs (or spaces indent) are now converted to the indent being used in the editor
* Hide non-pydev projects filter working
* Don't show assignments/imports after if __name__ == '__main__': in outline
* Code-completion: after a completion is requested, pressing '.' will apply that completion (and if it has parameters, they'll not be added).
* Code-completion: when a code-completion is applied with Ctrl pressed (toggle mode), parameters are not added.
* Assign to local variable/attribute handles constants correctly.
* psyco changed for Null object for debug (so, no changes are required to the code if psyco is used while debugging).
* Code-folding annotations won't change places.
* Pydev package explorer will correctly show outline for files if the project root is set as a source folder.
* Pydev package explorer: folders under the pythonpath have a package icon.
* Unittest runner: handles multiple selection.

Python for system administrators

2007-09-05T09:54:00.000-07:00

As a system administrator, you run across numerous challenges and problems. Managing users, disk space, processes, devices, and backups can cause many system administrators to lose their hair, good humor, or sanity. Shell scripts can help, but they often have frustrating limitations. This is where a full-featured scripting language, such as Python, can turn a tedious task into an easy and, dare I say it, fun one.

The examples in this article demonstrate different Python features that you can put to practical use. If you work through them, you'll be well on your way to understanding the power of Python.

Python 3000 Alpha 1 Released

2007-08-31T11:33:00.000-07:00

The first Python 3000 release is out -- Python 3.0a1.

http://python.org/download/releases/3.0/

Excerpts
Python 3000 (a.k.a. "Py3k", and released as Python 3.0) is a new version of the language that is incompatible with the 2.x line of releases. The language is mostly the same, but many details, especially how built-in objects like dictionaries and strings work, have changed considerably, and a lot of deprecated features have finally been removed.
This is an ongoing project; the cleanup isn't expected to be complete until 2008. In particular there are plans to reorganize the standard library namespace.
The release plan is to have a series of alpha releases in 2007, beta releases in 2008, and a final release in August 2008. The alpha releases are primarily aimed at developers who want a sneak peek at the new langauge, especially those folks who plan to port their code to Python 3000. The hope is that by the time of the final release, many 3rd party packages will already be available in a 3.0-compatible form.

WPF Designer and the IronPython Integration Sample

2007-08-06T13:09:00.000-07:00

If you've had the opportunity to work with WPF/.NET 3.0 yet, you've likely run into the x:Class attribute in XAML. If you specify a x:Class on a XAML page, during compilation the XAML compiler creates a class in code using the registered CodeDomProvider for the given language that you're compiling. This presented some challenges for getting the IronPython sample to work with the new designer.
There were two major problems:

1) The IronPython CodeDomProvider is not registered globally on the machine.
2)IronPython 1.1 does not support compiling to .NET-consumable types.

Some More Python 3000 Questions Answered

2007-08-01T13:27:00.000-07:00

Guido van Rossum answers some more Python 3000 FAQs on this forum

Some of the questions:

Q. Will Python 3000 have feature X (which has not been proposed yet)?

Q. Will implicit string concatenation be removed in Python 3000? (I.e., instead of ("a" "b") you'd have to write ("a" + "b").)

Q. Will the binary API for strings be standardized in Python 3000? (Depending on a compile-time switch, Unicode strings use either a 2-byte wide or 4-byte wide representation.)

Q. Why isn't the GIL (Global Interpreter Lock) recursive?

Q. Will we be able to use statements in lambda in Python 3000?

Q. Will Python 3000 require tail call optimization?

Q. Will Python 3000 provide "real" private, protected and public?

Q. Will Python 3000 support static typing?

Q. Why doesn't str(c for c in X) return the string of concatenated c values?

Guido van Rossum answers some Python 3000 FAQs on this forum

Here are some of the questions:

Q. I want to learn Python. Should I learn Python 2.6 or Python 3.0?

Q. If you're killing reduce(), why are you keeping map() and filter()?

Q. Multi-core processors will be standard even on laptops in the near future. Is Python 3.0 going to get rid of the GIL (Global Interpreter Lock) in order to be able to benefit from this feature?

Q. I prefer to use the same source code for 2.x and 3.0; I really don't want to have to use the 2to3 source conversion tool. Why can't you make that work?

IronMonkey: scripting Firefox natively with IronPython and IronRuby

Python documentation team is looking for members

2007-07-23T08:30:00.000-07:00

Georg Brandl sent out a call for people who wish to help with the python documentation.

Dear fellow Pythonistas,

as you may have heard, Python is going to get a new documentation system
soon [1]. As part of that effort, and in order to maintain the excellent
quality of the docs, we are looking for members of the maintainers team.
This is your chance to get involved with Python development!

There will be two main objectives of the group, or maybe two subgroups can
be formed:

* Maintaining the documentation contents:
- processing user submitted comments, bugs and patches
- helping out developers with docs-related matters, keeping an eye
on commits to ensure quality
- keeping the docs up-to-date, e.g. write new sections for new
Python 3000 features

The docs source will be in reStructuredText, which is already known to a
relatively high percentage of Python developers.

The new online version of the docs will contain features to add comments
and suggest changes, so it is expected that there will be some amount
of user involvement.

* Development of the toolset:
- fixing bugs in the package
- adding new output formats, e.g. info or pdf
- adding new features to the web application
- adapting it to new docutils features

My name is Denis Gobo and I am a SQL Server developer. I have been working with SQL Server since version 6. My other blogs are SQL Server Code,Tips and Tricks, Performance Tuning and http://sqlblog.com/blogs/denis_gobo/default.aspx. A couple of day ago I wrote a blog post titled Become A better Developer In 6 Months. In that blog post I wrote which books I would read and also what new language and framework I would learn. So as you can guess I have picked Python, PostgreSQL and Django. This blog will show my progress and struggle as I try to master these new things. After I am comfortable with these technologies I will trhrow in a little IronPyton for fun......stay tuned and wish me well
