ANN: tl.googlepagerank
by Thomas Lotze 24 Jan '07

24 Jan '07

I've released tl.googlepagerank 0.1, a package and a script for querying the Google page rank of individual URLs. This is done the same way the Google toolbar accesses page ranks. The package is available from the Python package index as a source distribution and as eggs for both Python 2.4 and 2.5: http://cheeseshop.python.org/pypi/tl.googlepagerank On a side note, this project is the first to live in the tl package namespace. Should a tl package or package namespace be in official use already, I'm not aware of it and would appreciate learning about it. >From tl.googlepagerank's README.txt: ===================================================== Run the script with any number of command line parameters. It takes each parameter to be a URL to query Google for. Each query may take some time, typically a couple of seconds. These are two sample runs, the dollar character representing your system's command prompt: $ googlepagerank http://www.google.com/ http://www.thomas-lotze.de/ 10 http://www.google.com/ 4 http://www.thomas-lotze.de/ $ googlepagerank http://www.example.com/foobar http://foobar http://www.example.com/foobar RE http://foobar Google page ranks range from 1 (unimportant) to 10 (important). An empty page rank means Google has not yet assigned a rank to the URL. "IO" instead of a page rank means there was an error contacting Google. "RE" means Google's response could not be understood. ===================================================== The code is maintained in a subversion repository at <https://svn.thomas-lotze.de/repos/public/googlepagerank>. There is a ViewCVS view on the repository available at <http://svn.thomas-lotze.de/public/googlepagerank>. The project is also described briefly at <http://www.thomas-lotze.de/en/software/>. -- Viele Grüße, Thomas

Dejavu 1.5.0RC1
by Robert Brewer 24 Jan '07

24 Jan '07

The Dejavu Object-Relational Mapper (version 1.5.0RC1) is now available and in the public domain. Get it at http://projects.amor.org/dejavu, or from PyPI: http://www.python.org/pypi/Dejavu/1.5.0RC1. Dejavu is an Object-Relational Mapper for Python applications. It is designed to provide the "Model" third of an MVC application. Dejavu avoids making decisions in the framework which are better left to developers, and avoids forcing developers to make decisions which are better left to deployers. In particular, deployers are allowed to mix and match storage mechanisms, including how and when to cache objects in memory, making it easier for deployers to tune applications to their particular environment. Dejavu provides: MODELING LAYER 1. A base Unit class for persisting objects to storage. 2. A base UnitProperty class for persistent object attributes. 3. ID Sequencers. 4. Associations between Unit classes. 5. Unit Engines, Rules, and Collections. 6. Aggregation and analysis tools. APPLICATION LAYER 1. Expressions: pure Python lambda querying. This is perhaps the most appealing feature of Dejavu. 2. Sandboxes, which serve as Identity Maps, transaction boundaries, and per-connection caches. 3. An Arena class for application-level data. STORAGE LAYER 1. A base StorageManager class and specification. Unlike many ORMs, Dejavu does not require you to have complete control of the back end. 2. Specific StorageManagers for: a. Microsoft SQL Server/MSDE b. Microsoft Access (Jet) c. PostgreSQL d. MySQL e. SQLite f. Shelve g. Firebird h. RAM i. Filesystem What's New in 1.5: http://projects.amor.org/dejavu/wiki/WhatsNewIn15 * Native ID sequencing. * Distributed transactions and tested isolation levels. * Complete database introspection and auto discovery. * New Firebird support. * New RAM Storage Manager. * New psycopg2 support. * New support for using the sqlite3 module built into Python 2.5. * Support for typed and typeless SQLite. * Support for SQLite :memory: databases. * Complete numeric precision and scale support. * Native date function support. * Complete M x N type-adaptation. * Bulletproof encoding support. * New 'range' function which returns the closed interval [min(attr), ..., max(attr)]. * New 'sum' function which returns the sum of all non-None values for the given cls.attr. * Multiple and custom Associations. * Improved performance (especially ADO). * New JSON encoder/decoder. * Short config names for Storage Managers. * ADO: New support for the CURRENCY datatype. * ADO: Improved string comparisons using Convert and StrComp. Upgrading to 1.5: See http://projects.amor.org/dejavu/wiki/UpgradeTo1.5 Robert Brewer System Architect Amor Ministries fumanchu(a)amor.org

FlightFeather Social Networking Platform 0.3.0
by George Belotsky 23 Jan '07

23 Jan '07

FlightFeather's goal is "social networking for everyone". This means that *anyone* should have a chance to run a *popular* social networking site -- on minimal hardware, and without wasting bandwidth. Release 0.3.0 is the current development release. It introduces a feature that allows easy submission of FlightFeather-hosted content to Digg. Generic utility functions perform most of the work, so it should be relatively straightforward to extend support to other social networking sites in the future. The current beta release of FlightFeather is 0.2.8. You can download these releases (free/open source under the GPL) from the "BoSStats" site, which runs on FlightFeather. http://www.bosstats.com/flightfeather.html You are always welcome to participate in the discussion on the "BoSStats" site; the topic covered (what makes a good boss, office politics, etc.) is valuable in and of itself. Please, however, refrain from posting test comments, as the site is live. A Brief Overview of FlightFeather and BoSStats ---------------------------------------------- FlightFeather is in its early stages, but it is functional. You can see the system in action on the BoSStats site. BoSStats is dedicated to improving the world of work: you can discuss what makes a good boss, or share your experiences of office politics. You can also comment and vote on the posts made by others. The application does not set cookies, and no registration is required for anything except voting. http://www.bosstats.com/ BoSStats is a good testbed for FlightFeather, and has value of its own, since meaningful advice about work-related problems is very hard to find. A "Wisdom of Crowds" solution -- particularly with strong privacy protection (see below) -- is a necessary addition to this field. FlightFeather's most important feature is that all write requests generate (or modify) HTML files. In consequence, a pure read (the most common operation) merely serves static pages. The major design focus for FlightFeather are responsiveness and performance; the system should eventually support very high traffic volumes. In addition, FlightFeather allows for a great deal of user privacy -- a critical, rapidly emerging problem in the social networking realm.

PyPy Trillke Sprints Feb/March 2007
by holger krekel 22 Jan '07

22 Jan '07

========================================================================= PyPy Trillke "EU and beyond!" sprints (25-28th Feb, 1-5th March 2006) ========================================================================= .. image:: http://www.trillke.net/images/HausPanorama0304_113kb.jpg Some two years and some thousands of commits later, the EU project period of the PyPy (http://codespeak.net/pypy) project is about to close ... and a new period to begin: we are going for a sprint of three days of focusing on EU reports and administrative issues, and another three day sprint of happy hacking on the numerous interesting open ends of PyPy, the source code. We also intend to discuss and state our view on the time after the EU period (March 2007 is the last EU funded month), because clearly the project will not stop after our successful (knock knock!) completion of the EU project. It's already clear that some of us seriously plan for a relaxation time, i.e. one without having many obligations. But that should not keep us from thinking and envisioning the development from April on. So to the Sprint: we have two parts of the sprint, first the EU and second the public all-invited part:: 26th Feb - 28th Feb EU reports and adminstrative sprint 1st March break day / arrival for coding sprint 2nd March - 4th March public coding "beyond EU" sprint days All days are meant as full days, so please arrive 25th Feb / 1st March and leave 5th March if you can (this help us with pairing, introductions and logistical planning). --------------------------------------------- Possible Topics for the coding sprint --------------------------------------------- * working on .NET, Java and other backends * working on the Javascript, Prolog or a new frontend * Tuning the JIT, refining approaches `[1]`_ * Fixing PyPy-1.0 problems / improving it (PyPy-1.0 is scheduled for Mid February, btw) * improving the py lib/py.test, build environments, preparing for server administration efforts from April on * Work on/with prototypes that use the new features that PyPy enables: distribution `[2]`_ (based on transparent proxying `[3]`_), security `[4]`_, persistence `[5]`_, etc. `[6]`_. * discussion about the time after March, and how to organize/co-ordinate ourselves * all topics that are of interest otherwise (including maybe working on some particular EU related topics still!) .. _[1]: http://codespeak.net/pypy/dist/pypy/doc/jit.html .. _[2]: http://codespeak.net/svn/pypy/dist/pypy/lib/distributed/ .. _[3]: http://codespeak.net/pypy/dist/pypy/doc/proxy.html .. _[4]: http://codespeak.net/pypy/dist/pypy/doc/project-ideas.html#security .. _[5]: http://codespeak.net/pypy/dist/pypy/doc/project-ideas.html#persistence .. _[6]: http://codespeak.net/pypy/dist/pypy/doc/project-ideas.html ----------------------- Location ----------------------- The sprint takes place at the Trillke Gut Steinbergstr. 42 Hildesheim, Germany http://www.trillke.net If you come to Hildesheim main station, take the Bus Number 3 (Hildesheimer Wald) and get out at "Waldquelle". Walking back a 100 meters gets you to a small street on the right leading to a big white building, the Trillke Gut. We'll have at least one larger room for sprinting, and a kitchen for our use. ----------------------- Accomodation ----------------------- We can probably arrange for some cheap or no-cost private accomodation, in private rooms located up in the house (and being part of "living groups" of 5-10 people). There also is a nice Guest house that has been used during recent events: http://www.gaestehaus-klocke.de/ and a four-star hotel 500 meters away from the Trillke: http://www.berghoelzchen.de/ ----------------------- Registration ----------------------- please subscribe to the pypy-sprint mailing list http://codespeak.net/mailman/listinfo/pypy-sprint and register by subversion: http://codespeak.net/svn/pypy/extradoc/sprintinfo/trillke-2007/people.txt or - if you have no checkin-rights - post to the pypy-sprint list above. -- merlinux GmbH Steinbergstr. 42 31139 Hildesheim http://merlinux.de tel +49 5121 20800 75 (fax 77)
