[ANN] Movable Python 0.4.6
by fuzzyman＠gmail.com 10 Feb '05

10 Feb '05

A new release of Movable Python is available - 0.4.6 This fixes a few issues including a bug in the Python 2.2 support, and a fix for a psyco/IPython incompatibility issue. We have a new icon and logo thanks to Aidan Ashby - http://aidan.voidspace.org.uk Due to bugfixes (in movpy) we can now offer a prebuilt environment for Python 2.2 that includes wxPython and SPE. The prebuilt environments feature updated versions of several components (SPE, IPython, readline) Downloads - http://sourceforge.net/projects/movpy Documentation - http://www.voidspace.org.uk/python/movpy What is Movable Python ? ------------------------- Movable Python is a way of building portable, standalone, Python environments. The result is a version of Python that can be used without having to install python on the target machine. (Currently windows only - but could be ported to Mac using py2app and Lunix using cx_freeze). This means you can carry around a prebuilt python environment on a USB memory stick - Python on a stick. Come and get your gannet ripple, python on a stick..... [1] This is useful for : * Machines where you don't have admin rights (can't install programs) * Where you need a portable 'Build, Test, and Run' Python environment (will nicely fit on a usb memory stick) * Having several versions of python on the same machine for forward/backward compatibility testing * Easily deploying python scripts without having to install python * Try before you buy - test python without having to install it, including new versions * 'Python Runtime Environment'. '.py' files can be associated with movpy With the addition of wxPython, SPE [2], and IPython [3] it becomes a full 'Build, Test, and Run' environment. What's Available ? ------------------- >From sourceforge ( http://sourceforge.net/projects/movpy ) : The source distribution that allows you to customize and build your own environments. This requires py2exe. Prebuilt environments for Python 2.2, 2.3, and 2.4. Environments are available either as 'basic' build, or 'standard' build. Basic comes with the standard library, psyco, and IPython. Standard has wxPython and SPE included. What Has Changed ? ------------------- 2005/02/07 Version 0.4.6a Movpy Icon and image added by Aidan Ashby - http://aidan.voidspace.org.uk Changes by Michael We use exec rather than eval (which shouldn't be used with `multiple statement code objects`) IPython isn't called if -p is on (psyco and IPython don't play well together yet) IPython won't be called if psyco.full() has been called in your script locals() and globals() are now passed explicitly to interactive() (optional if you use interactive yourself) (This was an attempt to make IPython work with psyco - which it doesn't yet !) Fixed a bug in Python 2.2 support - 'exclude_modules' now works ! Forced package import for encodings. SPE now works with python 2.2 - but still 'experimental'. Icon is now used in python 2.2 Plus the pre-built environments use newer versions of readline, IPython, and SPE Regards, Michael Foord http://www.voidspace.org.uk/python/index.shtml [1] For the 'Pythonically Challenged' this alludes to the python's sketch where John Cleese is dressed as an usherette selling ice-creams during the interval in a british film-house. He shouts: "Albatross! Albatross! Stormy-petrel on a stick! Gannet ripple!". Silly Monty Python reference supplied by John Davenport.

ANN: Constrict 0.1.0 DNS message parsing library
by Jason Smith 09 Feb '05

09 Feb '05

This message is to announce a new Python module, Constrict, which is useful for examining DNS messages that you receive either from a network capture or from a socket. While other DNS-related Python projects exist, none provide flexible message parsing and inspection. http://www.oes.co.th/projects/Constrict Constrict is BIND for Python: it is a Python library for parsing DNS messages using ISC's libbind. Constrict allows you to see DNS messages in two ways: * Direct access to the libbind parsing functions * A Python object with various meaningful attributes This software is available under the GNU General Public License, version 2. This is the initial release. Constrict evolved from an internal project development, so it has already seen much real-world testing. The wrapper to the BIND C API is thorough enough for most development, and the object-oriented view is quite intuitive for day-to-day queries and responses. Constrict is known to work with Python 2.3 and BIND 9 on Linux/i386 and Linux/ppc. -- Jason Smith Open Enterprise Systems Bangkok, Thailand http://www.oes.co.th

REMINDER: OSCON / Python 13 submissions deadline is Feb. 13th
by Kevin Altis 08 Feb '05

08 Feb '05

Don't forget that the deadline for submitting a talk or tutorial for OSCON / Python 13 is Sunday, February 13th. ka --- Kevin Altis altis(a)semi-retired.com http://altis.pycs.net/ The Call for Proposals has just opened for the 7th Annual O'Reilly Open Source Convention http://conferences.oreillynet.com/os2005/ OSCON is headed back to friendly, economical Portland, Oregon during the week of August 1-5, 2005. If you've ever wanted to join the OSCON speaker firmament, now's your chance to submit a proposal (or two) by February 13, 2005. Complete details are available on the OSCON web site, but we're particularly interested in exploring how software development is moving to another level, and how developers and businesses are adjusting to new business models and architectures. We're looking for sessions, tutorials, and workshops proposals that appeal to developers, systems and network administrators, and their managers in the following areas: - All aspects of building applications, services, and systems that use the new capabilities of the open source platform - Burning issues for Java, Mozilla, web apps, and beyond - The commoditization of software: who and/or what can show us the money? - Network-enabled collaboration - Software customizability, including software as a service - Law, licensing, politics, and how best to navigate other troubled waters Specific topics and tracks at OSCON 2005 include: Linux and other open source operating systems, Java, PHP, Python, Perl, Databases (including MySQL and PostgreSQL), Apache, XML, Applications, Ruby, and Security. Attendees have a wide range of experience, so be sure to target a particular level of experience: beginner, intermediate, advanced. Talks and tutorials should be technical; strictly no marketing presentations. Session presentations are 45 or 90 minutes long, and tutorials are either a half-day (3 hours) or a full day (6 hours). Feel free to spread the word about the Call for Proposals to your friends, family, colleagues, and compatriots. We want everyone to submit, from American women hacking artificial life into the Linux kernel to Belgian men building a better mousetrap from PHP and recycled military hardware. We mean everyone! Even if you don't want to participate as a speaker, send us your suggestions--topics you'd like to see covered, groups we should bring into the OSCON fold, extra-curricular activities we should organize--to oscon-idea(a)oreilly.com . This year, we're moving to the wide open spaces of the Oregon Convention Center. We've arranged for the nearby Doubletree Hotel to be our headquarters hotel--it's a short, free Max light rail ride (or a lovely walk) from the Convention Center. Registration opens in April 2005; hotel information will be available shortly. Deadline to submit a proposal is Midnight (PST), February 13. For all the conference details, go to: http://conferences.oreillynet.com/os2005/ Press coverage, blogs, photos, and news from the 2004 O'Reilly Open Source Convention can be found at: http://www.oreillynet.com/oscon2004/ Would your company like to make a big impression on the open source community? If so, consider exhibiting or becoming a sponsor. Contact Andrew Calvo at (707) 827-7176, or andrewc(a)oreilly.com for more info. See you Portland next summer, The O'Reilly OSCON Team
