[PD-announce] CALL FOR WORKS/PdCon09
by PdCon09 3rd International Puredata Convention 16 Feb '09

16 Feb '09

Please Check the info below, and the attached PDF... spread it out! Thanks.... PdCon09/CALL FOR WORKS: PdCon09 is the "Third International Puredata Convention", to happen in São Paulo-Brazil/July 2009 EMAIL: <<pdcon09(a)estudiolivre.org>> NEWS (feb 15th): - Online Submission procedure is opening on monday 16th!!! - New Templates and Forms will be posted when the submission is opened! - WE HAVE A NEW DEADLINE FOR THE SUBMISSION OF WORKS, MONDAY MARCH 15TH OF 2009!!! ABOUT THE EVENT: Puredata, or just Pd <http://puredata.info/>, is an open source tool for multimedia programming. Because of its open source nature, much of its development result from a community effort of developers worldwide. Some centers do have more people engaged, like the places that held the two previous conventions. the first convention took place in Graz, Austria, in 2004 http://puredata.info/community/projects/convention04/. The second happened in Montreal, Canada, in 2007 http://pure-data.ca/en/. It is a great satisfaction that we continue this event by bringing it to yet another continent, with the intent to promote the formation of an important group of developers locally. In fact, in may of 2008, we had a national convention in Brazil http://www.estudiolivre.org/tiki-index.php?page=Encontro%20PD, which followed the same format of the previous international conventions, and worked as a first gathering to organize this international event. The format includes the show of artistic works, academic works, discussion regarding the interests of the community, and diverse courses. CALL FOR WORKS VS. 2.5 (FEB 15TH) GENERAL CALL We invite artists, producers, developers and further enthusiasts of the open source tool Puredata to send works and projects alike in the following categories: A) Art Festival: (Art Installations, Concerts, Performances & Audiovisual Presentations). B) Mini-Courses & Workshops. C) Paper Sessions/Posters. D) Round Tables & Discussions. Applicants are invited to submit in multiple categories, especially if related (example: paper + artwork) - not that this will favor in the selection process. Please note we are looking for a diverse collection of works, hence there might be a selection among several similar proposals (and more unique and original ones might have some advantage). Let us know if you have an institution support that may cover travel expenses, we are looking for partnerships to help with funds. The event will be held in Sao Paulo, Brazil, from July 19th to july 26th, 2009. Possible (yet to be properly officialized) Locations & Partnerships: - MIS, Sao Paulo's Museum of Image & Sound. - PUC, School of Multimedia & Design. - SESC-SP, Sao Paulo. Promotional Support: - CCSL (FOSS Competence Center) http://ccsl.ime.usp.br/ WE HAVE A NEW DEADLINE FOR THE SUBMISSION OF WORKS: MONDAY MARCH 15TH OF 2009!!! Acceptance notice: APRIL 10th, 2009! Here is the address to send works & questions to: pdcon09(a)estudiolivre.org Addresses of the Official webpage for news updates & more info: http://convention.puredata.info http://estudiolivre.org/pdcon09 Proposals for the Art Festival: Performances, Concerts, Audiovisual Presentations & Art Installations (audio And/Or Visual): As it is the general concept of the event, we long for the discussion regarding the aesthetics and politics of Free / Open Source Software Culture & technology. In such context, we welcome all forms of works related to audio and/or visual, including real-time interactive works, improvisations, Live electronics/instrumental/electroacoustic mixes, Sound installations, Performances, Network art, Robotics, Software Art and Interdisciplinary works. Demonstrations and General Info about Artistic works can be submitted online in Portuguese, Spanish, or English. Please, specify the necessary materials so we can do our best to provide them. If language is a part of the artwork, the festival is open to any idiom, although subtitles in English should be provided when applicable. We look for art installations that adopted Puredata in its development. Nevertheless, at the last extent, we are open for works realized under the context of Puredata (using puredata in some part of the process) as well as open source tools. We are looking for partners to help us with tickets. Any suggestion is welcome. Note for ART-INSTALLATIONS (Audio And/Or Visual): In order to avoid dependence on travel funds from the event, it would be nice to have some works installed without the need for the artist(s) to be on-site. This also implies that such works should be technically simple. Call for Posters/Papers: Abstracts and papers may be submitted in English. The works will be organized in categories depending on what we receive. At first, we contemplate a greater distinction into 3 categories: Technical, Artistic and Theoretical. The topics are generally open to the usage of Puredata in interactive art production/research, the philosophy and social aspect of Free Open Source Culture, and scientific research. Some possible themes could include: - Programming Puredata externals - Puredata versus Max/MSP - Puredata versus SuperCollider, CSound, Processing and alike - Hacking Puredata - Future Projections for Puredata - Hacktivist culture - OpenContent and Creative Commons versus Intellectual Property forms - Finding an Art Historical context for Open-Source Software Art - Sampling and Plunderphonics as artistic strategies - Computer-Supported Cooperative Work - Networking - Live Coding - Philosophy, Culture and Sociology of Open Source Software and Open Works - Aesthetics of New Media/New Technology Art - Using Puredata in Science/Research & Artistic Works: (Digital Signal Processing, Generative Works, Artificial Intelligence/Life & Computer-Aided Work in General, User Interfaces - Human computer interaction/Virtual reality interaction -, Realtime Performance, Auditory/Visual perception and cognition, Acoustics/Psychoacoustics Modeling, Sound Synthesis, Timbre & Sound Models, Biological and medical uses of Puredata. And so on... Check Submission of Works for Poster & Paper guidelines If you wish to send a Poster, the limit is 4 pages, other works are limited to 6 pages. SUBMISSION OF WORKS: Round Table and Discussions should be proposed on the puredata list: http://lists.puredata.info/listinfo/pd-list, to be discussed and decided upon previously by the community and participants in general. The rest needs to be sent through our online system, with the provided Paper Template And Forms The online submission is due to open on monday, Feb 16th of 2009, check http://convention.puredata.info for news and links. Questions about it must be sent to <figocris(a)gmail.com>. Poster Guidelines: 120cm height x 90cm wide Papers are limited to 6 pages and must be submitted as PDFs. If you wish to send a Poster, please send a short Paper limited to 4 pages. We are studying the possibility of publishing the works online (both papers & Posters) in digital/hypertextual format s well as in a printed version with DVD-ROM. --------------------- http://convention.puredata.info pdcon09(a)estudiolivre.org _______________________________________________ Pd-announce mailing list Pd-announce(a)iem.at http://lists.puredata.info/listinfo/pd-announce

Consistency Problem - OS X[intel] - when modifying Abstractions
by Luigi Rensinghoff 16 Feb '09

16 Feb '09

Hi List, I notice a bug, thats coming back on OS X PD-extended. The occurs when i change an Abstraction, but not the original, but an active "instance" of a patch. Fpr example i have many instances of the same abstraction encapsulated in other abstractions. While patching i decide to change something - for example add an outlet - i open the instance change it and try to save it. PD seems to update all occurring abstractions and meanwhile the "parent-window" seems to disappear and it is not possible to save the patch anymore... I have to force quit PD after that. Strangely enough the change is saved in the abstraction..... but of course it is totally annoying for the workflow. I think i had this issue before and it disappeared in a more recent release of PD-Extended for OS-X Intel.... I am sorry i cannot post an example patch right now, maybe tonight... For now i would like to ask if anybody is having the same problem....and how to fix it, or maybe knows under which "subject" it might have been saved in the archive.. All the Best and a Happy New Year Luigi

startup flags and OSX
by e deleflie 16 Feb '09

16 Feb '09

All, I set -jack in my "startup flags" in Pd Extended (OSX) ... which worked well. But then when I removed -jack (from the startup flags) ... PD wont see the other devices .... its stuck on Jack. ...which leads me to believe that there is a text file written somewhere that PD uses, and -jack is stuck in there despite the fact that it doesn't show up in the "startup flags" anymore. Can anyone tell me where that text file is? (or how I can convince PD to stop using Jack?) Etienne

adding to file searchpath on pd-extended broken on OS 10.4?
by John Harrison 16 Feb '09

16 Feb '09

I wanted to add to the file searchpath for Pd-extended so I went to Prefs -> Path... and chose "new". From there I get a dialog box and am able to choose the path I wish to add. All good so far. But when I click "apply" after adding the path I get some hesitation, then: error: +/Applications/Pd-0.41.4-extended-20090126.app/Contents/Resources/extra/hcs: no such object error: +/Applications/Pd-0.41.4-extended-20090126.app/Contents/Resources/extra/hcs: no such object in the Pd console. The path does not seem to be added and if I restart Pd, the path I added is not on the list of paths. This is the case for the released Pd-extended 0.40-3 as well as the nightly builds of 0.41.4 for OS X 10.4 Intel. Even if I had added the path, though it probably wouldn't have solved my problem: I was trying to find a platform-independent (at least for OS X and Linux) way for pd to find gverb using |plugin~|. On OS X from the terminal if I do: export LADSPA_PATH=/Applications/audacity/plug-ins open Pd-0.41.4-extended-20090126.app then |plugin~| finds gverb successfully. But I wanted to find a way to extend the LADSPA_PATH ideally from a Pd patch itself or, short of this, without having to go to the terminal to start Pd. Of course the location of gverb is different between Linux and OS X and what I'm looking for is an easy way for |plugin~| in Pd to find gverb on either platform. Ideas? Thanks, -John

Re: [PD] video bluescreen

Hi Apologies for the slowness of my reply. Thanks both for the examples. I couldn't get pix_background working Ben but it seems to be not what I'm looking for on this occasion anyway. Mark, managed to see yours working, yep its pretty raw but it's a start which is what I needed. Many thanks. a+ gar > You don't actually load a base image into pix_background, you send > a [reset( message to the [pix_background] object and it takes a > snapshot of whatever's in front of the connected camera (or > incoming video stream).

sndfiler - or other ogg audio wavetable object in pd-extended
by glerm soares 13 Feb '09

13 Feb '09

Hello, Is there new versions of the [sndfiler] object or something similar (an object similar to [soundfiler] that could read ogg sound files into tables ) that comes with pd-extended compilation? Why pd-extended can't compile this? I could not find the object at sourceforge svn and the version at http://grh.mur.at/software/sndfiler.html is not compiling here - make can't find m_fifo.h and g_canvas.h but I could not file those headers at svn sorry if i 'm just lost... thanks glerm
