Greetings, I'm pleased to announce that the program for the first-annual EuroSciPy Conference is now available at: http://scipy.org/EuroSciPy2008#schedule Conference Date and Venue ------------------------- The EuroSciPy Conference will be held July 26-27, 2008 in Leipzig, Germany. http://scipy.org/EuroSciPy2008 Registration ------------ The direct link to the registration site is here: http://www.python-academy.com/euroscipy/index.html The registration fee is 100.00€ for early registrants and will increase to 150.00€ for late registration (after June 15). Pre-Conference Courses ---------------------- If you like to extend your trip to Leipzig, you can attend pre-conference courses: 1.) 2-day course "Introductory to Python for Programmers" followed by a 2.) 3-day course "Python for Scientists and Engineers" http://scipy.org/EuroSciPy2008#courses About EuroSciPy --------------- EuroSciPy is designed to complement the popular SciPy Conferences which have been held for the last 7 years at Caltech (the 2008 SciPy Conference in the U.S. will be held the week of August 19-24). Similarly, the EuroSciPy Conference provides a unique opportunity to learn and affect what is happening in the realm of scientific computing with Python. Attendees will have the opportunity to review the available tools and how they apply to specific problems. By providing a forum for developers to share their Python expertise with the wider commercial, academic, and research communities, this conference fosters collaboration and facilitates the sharing of software components, techniques and a vision for high level language use in scientific computing. Typical presentations include general python use in the sciences, as well as NumPy and SciPy usage for general problem solving. Beyond the excellent talks, there are inter- session discussions that prove stimulating and helpful. Registration will include breakfast, snacks and lunch for Saturday and Sunday. Please pass this announcement along to any other relevant contacts. Many Thanks, Mike Müller

30 May '08

The wiki announcing the initial source code release of OSHIP is available at: http://www.openehr.org/wiki/display/dev/Python+developer%27s+page Including links to installation and initial startup. There is a news release on Linux Medical News that contains more background and project justification information: http://linuxmednews.com/1212171292/index_html I am inviting expert discussion on the circular import issues due to the desire to adhere as closely to the openEHR specifications as possible. The issues are in the interfaces being implemented with schema types that are the same or at least in the same packages as the implementations of those classes. http://www.openehr.org/svn/ref_impl_python/TRUNK/oship/src/oship/openehr/rm… Thanks for your comments. --Tim -- Timothy Cook, MSc Health Informatics Research & Development Services LinkedIn Profile:http://www.linkedin.com/in/timothywaynecook Skype ID == timothy.cook ************************************************************** *You may get my Public GPG key from popular keyservers or * *from this link http://timothywayne.cook.googlepages.com/home* **************************************************************

ANN: NumPy 1.1.0
by Jarrod Millman 29 May '08

29 May '08

I'm pleased to announce the release of NumPy 1.1.0. NumPy is the fundamental package needed for scientific computing with Python. It contains: * a powerful N-dimensional array object * sophisticated (broadcasting) functions * basic linear algebra functions * basic Fourier transforms * sophisticated random number capabilities * tools for integrating Fortran code. Besides it's obvious scientific uses, NumPy can also be used as an efficient multi-dimensional container of generic data. Arbitrary data-types can be defined. This allows NumPy to seamlessly and speedily integrate with a wide-variety of databases. This is the first minor release since the 1.0 release in October 2006. There are a few major changes, which introduce some minor API breakage. In addition this release includes tremendous improvements in terms of bug-fixing, testing, and documentation. For information, please see the release notes: http://sourceforge.net/project/shownotes.php?release_id=602575&group_id=1369 Thank you to everybody who contributed to this release. Enjoy, -- Jarrod Millman Computational Infrastructure for Research Labs 10 Giannini Hall, UC Berkeley phone: 510.643.4014 http://cirl.berkeley.edu/

About Release 0.4.4: ==================== Bugfix release for poor tolerance of unsupported options in the server. About Release 0.4.3: ==================== Bugfix release for an issue with the server's detection of the end of the file during a download. About Release 0.4.2: ==================== Bugfix release for some small installation issues with earlier Python releases. About Release 0.4.1: ==================== Bugfix release to fix the installation path, with some restructuring into a tftpy package from the single module used previously. About Release 0.4: ================== This release adds a TftpServer class with a sample implementation in bin. The server uses a single thread with multiple handlers and a select() loop to handle multiple clients simultaneously. Only downloads are supported at this time. About Release 0.3: ================== This release fixes a major RFC 1350 compliance problem with the remote TID. About Release 0.2: ================== This release adds variable block sizes, and general option support, implementing RFCs 2347 and 2348. This is accessible in the TftpClient class via the options dict, or in the sample client via the --blocksize option. About Release 0.1: ================== This is an initial release in the spirit of "release early, release often". Currently the sample client works, supporting RFC 1350. The server is not yet implemented, and RFC 2347 and 2348 support (variable block sizes) is underway, planned for 0.2. About Tftpy: ============ Purpose: -------- Tftpy is a TFTP library for the Python programming language. It includes client and server classes, with sample implementations. Hooks are included for easy inclusion in a UI for populating progress indicators. It supports RFCs 1350, 2347 and 2348. Dependencies: ------------- This library was developed against Python 2.3+. Trifles: -------- Project page: http://sourceforge.net/projects/tftpy/ License is the CNRI Python License. http://www.opensource.org/licenses/pythonpl.php See COPYING in this distribution. Limitations: ------------ - Server only supports downloads. - Client only supports downloads. - Only 'octet' mode is supported - The only option supported is blksize Future: ------- - Upload support - netascii support - More complete test harness Author: ======= Michael P.

EuroPython 2008: Talk Submissions Extension plus Early Registration Reminder
by Paul Boddie 28 May '08

28 May '08

First of all, a reminder to those of you considering registering for EuroPython 2008, held in Vilnius, Lithuania from 7th to 12th July (talks from 7th to 9th, sprints from 10th to 12th): the early registration deadline is on Saturday 31st May, and if you would like to take advantage of the reduced registration fee, now is the time to navigate to the EuroPython site and to make your registration: http://www.europython.org/Registration For the impatient, here's a link to the registration form itself: http://registration.europython.eu/ Talk Submissions Period Extended -------------------------------- The original deadline for submitting talk proposals for EuroPython 2008 passed on Thursday 22nd May, and although there have been quite a few submissions, the EuroPython organisers would like to encourage a few more! So, we have now decided to give all potential submitters some more time to put together proposals and send them in for consideration. What this means is that anyone who had considered making a talk proposal but then found themselves short of time before last Thursday can now aim for the new deadline of Monday 2nd June - there's even a weekend before the deadline for anyone needing "quiet time" to sketch out their proposal! As always, the EuroPython organisers realise that the deadlines we've set aren't always compatible with everyone's personal schedule. Remember that we're only looking for proposals at this point, not the entire talk or materials, although we obviously expect those things to be ready for the conference. ;-) Take a look at the Call for Participation for all the details: http://www.europython.org/CallForParticipation Or go straight to the page for talk submissions: http://www.europython.org/Talk_Submissions We look forward to seeing your proposals and hopefully seeing you in Vilnius!

VIFF 0.6 released
by Martin Geisler 28 May '08

28 May '08

On behalf of the VIFF Development Team, I am happy to announce the release of VIFF version 0.6: Tar/GZ: http://viff.dk/release/viff-0.6.tar.gz Tar/BZ2: http://viff.dk/release/viff-0.6.tar.bz2 Zip: http://viff.dk/release/viff-0.6.zip Exe: http://viff.dk/release/viff-0.6.win32.exe Changes since VIFF 0.5: The average time for a secure comparison was reduced by 60-70%. Comparisons now work with an actively secure multiplication protocol. A memory leak was fixed. Converted documentation to new Sphinx format, please see: http://viff.dk/doc/index.html About VIFF: Virtual Ideal Functionality Framework is a framework for creating efficient and secure multi-party computations (SMPC). Players, who do not trust each other, participate in a joint computation based on their private inputs. The computation is done using a cryptographic protocol which allows them to obtain a correct answer without revealing their inputs -- even when some players try to cheat. Operations supported include addition, multiplication, and comparison, all with Shamir secret shared outputs. -- Martin Geisler VIFF (Virtual Ideal Functionality Framework) brings easy and efficient SMPC (Secure Multi-Party Computation) to Python.
