Hi I would like to announce a Python interface for MOSEK. MOSEK is a software package for solution of large scale optimization problems. Hence, MOSEK can solve * linear programming, * quadratic programming, * conic quadratic programming, * mixed-integer integer programming, * as well as nonlinear convex programming problems. The Python interface to MOSEK makes it easy and efficient to solve the above mentioned problem types from within Python. A manual about the interface is available at http://www.mosek.com/fileadmin/products/5_0/tools/doc/html/pyapi/findex.html Further information about the interface is available at http://www.mosek.com/index.php?id=56 The Python interface is included in the current version 5 distribution of MOSEK. MOSEK is commercial software but a free trial can be downloaded at http://www.mosek.com/download/ Feel free to contact MOSEK if you have any questions or comments about MOSEK and the Python interface. See http://www.mosek.com for contact details. Best regards Erling D.

by Alex Holkner 19 Nov '07

19 Nov '07

Greetings I am pleased to announce pyglet 1.0 beta 2, a cross-platform windowing and multimedia package useful for developing games and other visually-rich applications. http://www.pyglet.org pyglet is written entirely in Python, with no external requirements needed to develop applications for Windows XP, Mac OS X or Linux. pyglet allows applications to open any number of top-level windows and draw into them using the OpenGL API. Multiple-monitor setups are well-supported. Applications using pyglet can also play sound and music samples in surround-sound, taking advantage of hardware acceleration where available. With the addition of a single DLL based on FFmpeg, applications can read compressed sound and video in many formats. pyglet is provided under the BSD open-source license, allowing you to use it for both commercial and other open-source projects with very little restriction. Cheers, Alex.

OSDC 2007's Fabulous Keynotes!
by Richard Jones 18 Nov '07

18 Nov '07

Final reminder! Register now for the Open Source Developers' Conference 2007: http://www.osdc.com.au/registration/index.html The Open Source Developers' Conference is an Australian conference covering talks about software development for open source languages and projects; regardless of operating system. There will be 3-4 streams of talks over the three days of technical programme, with combined keynotes at the start of each day. Key information: 26th November - Tutorials 27th - 29th November - Technical programme 28th November - Google Conference Dinner Royal on the Park Hotel Cnr Alice & Albert Streets Brisbane CBD Queensland Each full registration ($325) includes one dinner ticket (until sold out). Single day tickets are also available for $150. Check out our tutorial program at http://www.cgpublisher.com/conferences/107/web/program-detail.html Keynote talks this year include: Rusty Russell: "C: A Humbling Language" ------------------------------------------------------------------ Some languages have beautiful constructs and elegant power. Others have novelty and fresh ideas. Surely C is a sometimes-necessary evil, and been around so long that there's nothing new to discover about it? So what kind of retarded masochist would select C as their language of choice? And why? Rasmus Lerdorf: "Exploring the Broken Web" ------------------------------------------------------------------ XSS and XSRF has been a thorn in the side of the web for years now. Rasmus will show some very common mistakes people make and tie it to the real world by showing a vulnerability in actual sites. Paul Fenwick: "An Illustrated History of Failure" ------------------------------------------------------------------ The average individual is given little scope for failure, at least not the type that really matters. The opportunity for catastrophic failure, that influences nations or continents, has been traditionally reserved for royalty, parliament, and others in a position of great leadership. However in recent times we have developed a profession who have the opportunity to fail like never before. A profession that can make mistakes that are so monumental, so wide-reaching, and so costly they can shake civilisation to its very core. This elite group, rarely seen by every day society, are the foundation upon which modern society depends. The few, the proud, the Software Developer. Join us for a voyage of discovery, as we travel back through history to some of the most monumental failures the world has ever seen. Jonathan Oxer: "Software Freedom: Pragmatic Idealism?" ------------------------------------------------------------------ The Free / Open Source Software (FOSS) community is incredibly diverse with a corresponding variety of reasons for participation. At one end of the scale is dreamy idealism, which aims to free all information for the good of mankind. At the other end is economic pragmatism, which sees Open Source as a powerful business opportunity and software development model. Is there common middle ground where both ends of the spectrum can meet? Can Free Software really can be Pragmatic Idealism? And what are we doing as a country in terms of building a sustainable local ICT industry? Be a part of this fantastic conference and help it be the best developers' conference this year! If your business would like to benefit from exposure to many of Australia's best open source developers then perhaps you should consider sponsorship. We have a wide range of sponsorship options, to find out more information please visit: http://www.osdc.com.au/sponsors/index.html
