GRiNS 1.0 (Multimedia authoring software in Python) available
by Jack Jansen Aug. 31, 1999

Aug. 31, 1999

[Warning: This message could be seen as being commercial] Folks, we proudly announce the first commercial release of GRiNS, our multimedia authoring and playback system for the internet. It allows you to create SMIL presentations (SMIL is the W3C standard for multimedia over the net, and used by applications such as RealNetworks G2 player), and completely written in Python. Well, completely: there's a few extension modules involved to make various media rendering toolkits available, but the whole application framework is in Python (And most of the extension modules have found their way back into the Python community, or will do so shortly, of course). Thanks to Python we're able to release GRiNS for all three major platforms at the same time: Macintosh, Windows and Unix (SGI and Sun; sorry, no Linux yet, due to the fact that we don't know of any decent media libraries (esp. movie libraries), so please enlighten us if you know of something). If you want to have a look at what a Python multiplatform application can look like check it out at http://www.oratrix.com/GRiNS . And feel free to ask us, Sjoerd Mullender (sjoerd(a)oratrix.com) or me, if you want to know anything about technical details (or commercial details, which we will duly forward:-). Oh yes: if anyone has good suggestions for places they always use for being kept informed about new software (i.e. who we should inform about this release) we'd be happy if you could share them with us. Here's the press release, for completeness sake: --------------------------------------------------------- Oratrix Development BV http://www.oratrix.com/ GRiNS for SMIL WILL TRANSFORM MULTIMEDIA WEB AUTHORING Amsterdam, The Netherlands (August 30, 1999) - Oratrix Development BV today announced the release of GRiNS for SMIL V1.0, a unique authoring and presentation system for local and streaming media on the Web. GRiNS/SMIL allows content providers to create adaptive multimedia productions that tailor content to the needs and resources of the user community. Working together with RealNetworks® RealSystem® G2, GRiNS provides access to the full capabilities of the SMIL language on Windows, Macintosh and UNIX systems. Users on all these platforms can finally design multimedia presentations with adaptive content. According to Dick Bulterman, founder and managing director of Oratrix Development, "GRiNS/SMIL will transform Web multimedia from a one-size-fits-all paradigm to one in which the needs, resources and capabilities of individual users can determine the quality and content provided inside a streaming media presentation." Presentations can be made that not only adjust for bandwidth constraints, but also for language (for example, English and Spanish), or media type (text, image or video). "GRiNS/SMIL fills a critical gap in the authoring market," adds Bulterman. "We greatly simplify the process of creating SMIL presentations for the RealNetworks RealPlayer® G2 at an affordable price." Bulterman, described by UK's Internet Magazine as one of the Web's 10 behind-the-sceens heroes, says that the system's ability to create adaptive presentations will open up new value-added markets by allowing authors to tailor their content to the needs and resources of their clients. Commenting on the release, Len Jordan, senior vice-president, Media Systems, RealNetworks, Inc. said: "GRiNS provides an intuitive and easy complement to Realslideshow(TM) for users who want to exploit multiple media types and advanced capabilities of both SMIL and RealSystem G2." Geoff Freed of CPB/WGBH National Center for Accessible Media added: "The ability of GRiNS/SMIL to provide control of adaptive content for both streaming media and the local GRiNS player will significantly lower the barrier for creating presentations that are accessible to the widest possible range of Web users." Ivar Brinkman of Elsevier Science Publishers noted: "The fact that GRiNS is available for Macintosh and UNIX as well as Windows-98/NT allows Elsevier to work with all of our authors in evaluating new approaches to showcase and enhance our printed publications." GRiNS/SMIL was developed by Oratrix Development BV, an Amsterdam-based spin-off of CWI, the Dutch national center for mathematics and computer science. Oratrix Development is winner of the McKinsey & Co. "New Venture" award and has been selected by the Twinning Venture Capital Network in the Netherlands. GRiNS/SMIL has been tested by over two thousand users world-wide in beta form. GRiNS/SMIL is available at http://www.oratrix.com/GRiNS/.

molecular modeling toolkit (mmkt)?
by Randy M. Wadkins Aug. 31, 1999

Aug. 31, 1999

Has anyone used the mmtk on a Mac? I have no experience whatsoever with Python, but would like to use the mmkt. If anyone has experience porting, say, Python and C code for Linux to the Mac, I would very, very much appreciate someone holding my hand in getting the mmtk ported. Thank you all in advance. --Randy ****************************************************************** "As the light changed from red to green to yellow and back to red again, I sat there thinking about life.

Maybe you should ask him to do this both on a working and a nonworking machine. Sys.path should be [applicationfolder, application, ':'].

installing modules
by Andrew Flaus Aug. 25, 1999

Aug. 25, 1999

Hi I've just installed macpython 1.5.2b1 on an iMac. As a first exercise, I am trying to complete a little task which would be immensely aided by Hinsen's 'ScientificPython 2.0' modules (available from starship). Unfortunately I am having trouble making these functional and there doesn't seem to be any mac-specific simpleton's documentation or FAQ: 1. Even after editing sys.path to include the path, re-running the configure application and restarting Python, the interpreter resolutely refuses to see the modules at all. 2. If I transfer a .py file, say xxx.py, into one of the functional modules (e.g. Numeric), I can import it and it compiles to xxx.pyc. However, when I do dir(xxx) I get only 4 "underscored" (i.e. _yyy_) entries in the list and the commands the modules provide are not recognised. I'm sure its straightforward but can someone please tell me what I'm doing wrong here. In exchange, I'd be happy to write up the explanation and contribute it plus some of the real newbie things I had to discover to an Macpython FAQ or hints page. Thanks. Andrew.

by Robin Dunn Aug. 25, 1999

Aug. 25, 1999

Hi all, I'd like to jump in at this point and add that contributions of Mac hardware and development tools for this project would be greatly appreciated. This would allow me to better manage the wxMac version of the project, ensure compatibility between versions, synchronize releases and be able to provide support for the toolkit as a whole instead of just for a few flavors of it. To those of you who can donate time to help, that is wonderful and thank you. To the rest of you, if you have spare machines of sufficient capabilities to be useful on a project like this, please consider wxPython a worthy project to donate to. If you know of somebody else who might be able to help, please forward this request on to them. (Anybody have Steve Jobs' email address? ;-) While considering this request please think of the potential benefit to the world-wide software development community, as well as the potential tax write-off! <wink> -- Robin Dunn Software Craftsman robin(a)AllDunn.com http://AllDunn.com/robin/ http://AllDunn.com/wxPython/ Check it out! > Bill Dozier dozier(a)abs.net > Tue, 24 Aug 1999 16:38:06 -0400 > > Guido, > > I'm interested; in fact, I've sort of hacked around trying to see if it > would build and it looked promising.

toolboxmodules.ppc.slb error on *some* Macs
by Niel M. Bornstein Aug. 25, 1999

Aug. 25, 1999

My client has reported the following error on 2 out of 20 of his clients' Macs, both of them PPC's of some sort running MacOS 7.5.1. This is a stand-alone application built with Python 1.5.2b1. I apologize for the rough transcription of the traceback, but my client knows nothing about the Mac, and he's not been the best guy to get this kind of info from. Traceback(innerMost last): File "Kyoto:projects:pivotal:1.01b3:Plink.PY",Line7, in?: File "Kyoto:Development:Python 1.5.2b1:Mac:LIB:frmeWork.py", Line 8, in? Import Error: Toolbox modules.ppc.scb: The Named Libreary Wasn't found: Does anyone have any idea what this error might actually be refering to? Line 7 in Plink.py is "import FrameWork" and line 8 in framework.py is "from AE import *". Do I need to copy toolboxmodules.ppc.slb and/or the alias AE.ppc.slb to these Macs? Thanks, Niel

Status of MacPython?
by Jim Harrison Aug. 25, 1999

Aug. 25, 1999

I'm new to Python (but in the process of getting hooked) and I'm interested in working in python on the Mac in addition to working with Zope (=Python) on Linux. I guess I can add my name to those who will be working with both Mac and Linux and who would like to see an efficient built-in solution for the tab vs. space problem in line indenting and other outstanding issues. I would also vote for syntax coloring in the IDE even if multiline strings are not cleanly handled. It would be really useful to me to see some brief comments on the future of Mac Python from Jack and/or Just, even though I know that crystal-ball stuff is inexact. Is it anticipated that standard python will compile for Mac OS X or will a special distribution be required? Will Mac Python continue as a separate entity? Are additional Mac Python releases (i.e., the 1.5.2 final) anticipated? If MacPython will continue in the future, what's the prognosis of the current development effort?

by Bill Dozier Aug. 24, 1999

Aug. 24, 1999

Guido, I'm interested; in fact, I've sort of hacked around trying to see if it would build and it looked promising. I just borrowed a header file or two from Stefan's code to get the right preprocessor variables set and then it looks like all I need to do is comment out the code that depends on parts of the library that Stefan doesn't have ported yet. Since Robin's wxPython C++ code is mostly SWIG-generated and therefore pretty platform-neutral, I expected this to be the case. I was planning to try again once the final 1.5.2 (with CW Pro 5 projects for building extensions) and the final Mac wxWindows were released. I would really like to see this fly since I don't want to have to learn any OS-specific API if I can help it and I really don't like Tk on the Mac. If no one with more MacPython experience than me wants to do this, then I guess I will give it a go.

Robert Roebling: wxPython

Anybody interested in porting wxPython to the Mac? WxWindows has already been ported, so it's probably a simple task. This is about the only cross-platform GUI toolkit that works on the Mac besides Tk (most of the new Linux offerings are "cross-platform" meaning Unix and Windows...). Please help this guy!
