Call for participation - livecoding festival in Sheffield this summer, presentations and performances, with commissions available. Live patching / packet forth related submissions welcome! ====================================================================== _ ___ ____ ____ _ _ ____ _ | | / _ \/ ___/ ___| | | (_)_ _____ / ___|___ __| | ___ | | | | | \___ \___ \ | | | \ \ / / _ \ | / _ \ / _` |/ _ \ | |__| |_| |___) |__) | | |___| |\ V / __/ |__| (_) | (_| | __/ |_____\___/|____/____/ |_____|_| \_/ \___|\____\___/ \__,_|\___| ---------------------> LOSS Livecode Festival <----------------------- Sheffield, UK -- 20-22 July 2007 http://livecode.access-space.org/ In association with Access Space, TOPLAP and lurk When we improvise music, we are creating music while it is being performed. "Live Coding" is the creation of software while it is being executed; the software in turn generating music or video. Thanks to dynamic programming languages, the live coder is able to modify and extend their program without restarts, their music and/or visual growing with the code that describes it. This way of working allows instant results for every sourcecode edit. Programming becomes a fast, creative process - expressive enough that a whole audio/visual performance may be created as software. Live Coding began during the 1980s, primarily with FORTH and Lisp. In recent years new live coding environments and languages such as Chuck, Fluxus, Impromptu and SuperCollider 3 have appeared, with enthusiastic communities growing around them. Live Coding performances have also used Smalltalk, PureData, Scheme, Perl, Haskell, Ruby, Python... In early 2004 the "Temporary Organisation for the Promotion of Live Algorithm Programming" (TOPLAP) was formed to support open dialog between all live coders. Since its early beginnings in a smoky bar in Hamburg, TOPLAP has reached 178 members worldwide, gaining coverage in mass media and collaboratively organising several international meetings. In 2005 Access Space initiated the L.O.S.S. project (http://loss.access-space.org) to support free music creativity and distribution. It featured a series of commissions leading to a Creative Commons licensed audio CD and repository website produced entirely with open source tools. Continuing their series of LOSS commissions and events, Access Space have teamed up with TOPLAP and lurk to create a three day international festival, bringing live coding musicians and video artists together to explore and showcase new approaches in live performing and participatory arts. ---> CALL FOR PARTICIPATION <----------------------------------------- Your performance and/or presentation proposal is called for. For the latest version of this call, please refer to http://livecode.access-space.org/ Commissions are available to help realise ambitious projects and performances. Presenters and performers will gain free entry throughout the festival, and those without institutional support may apply for a small bursary. ---> IMPORTANT DATES <--- * 14th March - Call for participation * 14th April - Deadline for proposals * 1st May - Notification of acceptance * 16th June - Copy deadline for proceedings (to be confirmed) * 20th-22nd July - Conference - schedule TBA ---> PRESENTATIONS <--- Short (up to 20 minute) presentations during a day long symposium. The remit is broad, but possible subjects may include * A demo of a novel live coding language/environment * Historical context of live coding * Live coding without computers * Critique of live coding practice * Live patching * Reflections on live coding experiences * Adapting general purpose languages to live coding * Analysis of live coding performances * Live algorithms that live code * Life coding * Portable live coding devices * Reflective/self-modifying code * Live visualisation of sourcecode * Collaborative networked live coding * ... Proposals do not have to be long - however much or little you need to explain your ideas is fine. If you are unsure if you can make it, submit your idea anyway - we may be able to accommodate a small number of remotely streamed presentations for those unable to attend in person. There will also be time for a brief (around three hours) introductory workshop. Please indicate if you would like to be involved. ---> PERFORMANCES <--- There will be at least two evenings of performances, ranging from 10 to 40 minutes. Please outline what you would like to perform, including technical requirements. We plan to have at least three data projectors, many pairs of small speakers for participatory improvisations, enough headphone amps for 100 pairs of headphones, and a big stereo sound-system for 'traditional' performances. Please state your preference, and feel free to be creative (see commissions below). We are also thinking about a pre-event in London, UK some days before the festival, let us know if you would like to take part. ---> PROCEEDINGS <--- If your proposal is accepted you will be encouraged to submit short texts and images for publication in the proceedings. All speakers and performers will receive a free copy at the beginning of the conference. ---> COMMISSIONS <--- If you would like time or resources to develop a new way of performing, some new language or software feature, or something else interesting then please include a short estimated budget in your brief, which may include an artist fee. Note that due to funding constraints the project should have a strong audio component. The maximum commission will be of £1000 (about 1470 euro). ---> BURSARY <--- A small bursary is available to contribute towards travel and accommodation. Please include an estimated budget for your attendance and we will apportion this money based on need. Money is however very short, if you are a member of an academic institution we are keen to help you apply for local funding. ---> PROPOSAL SUBMISSION <--- Preferably in plaintext, but all common formats are accepted. Supporting material including web links to previous work, audio and video files are welcome but not mandatory. Proposals should arrive before midnight, 14th April 2007. Proposals are accepted by email (preferred): livecode(a)access-space.org Or by post: LOSS Livecode c/o Alex McLean Access Space 1 Sidney Street Sheffield S1 4RG Royaume Uni If sending via email please do not include large attachments - either include URLs or contact us in advance. If sending via post include an email address so that we may confirm receipt. ---> MAILING LIST <--- As members of the "keep avant garde internet tidy" campaign, we keep our cross posts to a minimum. To continue receiving news of the conference, please sign up to our mailing list: http://lists.lurk.org/mailman/listinfo/lc/ ---> ABOUT ACCESS SPACE <--- Based in Sheffield, Access Space is the UK's first "Free Media Lab" - a community space equipped with locally recycled computers running free, open source software.

pdp 0.12.5-darcs on Linux
by Jamie Bullock 15 Mar '07

15 Mar '07

Hi, I am trying to get pdp working on my Linux box: Ubuntu 6.10 (2.6.17-10-generic, X11 7.1.). I am using the fglrx video driver with direct rendering enabled. So... How do I get pdp to render to the screen? [pdp_xv] loads correctly but sending it a |create( message gives: pdp_xv: cant open display :0 [pdp_sdl] and [pdp_glx] both cannot be instantiated: '...couldn't create', despite the fact that I compiled with --enable-sdl and --enable-glx. Anyone know what I need to do to get this working? Thanks, Jamie

Fw: adding external-direcetories to paths

Hi Luigi, I'm on Windows for now. Steffen has been kind enough to to guide me in the right direction, but I'm not quite there yet, so any additional input you might have on the matter would be a much appreciated. Cheers!

Re: [PD] adding external-direcetories to paths
by Thomas Jeppesen 14 Mar '07

14 Mar '07

Thanks again Steffen, I think everything is a bit easier to grasp now, all though I'm having trouble making the ':'-trick work as expected. I've tried seperating paths with ';' instead, but when I load PD the next time each path has been assigned it's on path-line in the preferences. Maybe assigning a path in the object itself, as you propose, is my solution too. Yes I was thinking about Labsalonen at LAB, at least it could become a place where people who are into PD can meet once a month, since whats going on at Labsalonen is what people themseles wants to do. But if there's enough interest for a dedicated PD-patching-group in Copenhagen I'm sure something can be arranged. Unfortunately I havn't got the time to arrange or manage such a group, but I could be the contact who can open the doors at LAB and make the room available from time to time. Cheers!

forcing focus to and minimizing the GEM window
by Matteo Sisti Sette 14 Mar '07

14 Mar '07

Hola, Do anybody know a way to mininimize the GEM window, and then restore it and bring it to front? I mean, obviously, controlled by PD message, not by mouse. Either in full screen or not: both would be useful to me (assuming I can have a borderless screen-size zero-positioned gem window) Oh, sorry: in Windows XP. THE LONG VERSION: It's because I need to run two applications: GEM and a Flash projector, and I need to be able to switch between them remotely via (for example) MIDI events. At any moment, one of the two would be visible and doing things, and the other invisible and waiting. So, I thought I may have one of the two on front and the other on bottom, if only I could just minimize and restore one of the two. As far as I know, there's no way to minimize and restore the flash projector window (only switch between fullscreen and window mode) via programming; so I just hoped there was a way of doing it in GEM. Or, any tool that could tell Windows to switch to a certain task would do the job (as long as I can send a midi or TCP/IP message to this tool). Or a command-line tool would do, since I could execute it from flash. However, all this goes far O.T. I just thought it would be nice to let you know why the heck I'm asking that :) Thank you in advance M. ----- Original Message ----- From: <pd-list-request(a)iem.at> To: <pd-list(a)iem.at> Sent: Wednesday, March 14, 2007 10:43 AM Subject: PD-list Digest, Vol 24, Issue 66 Send PD-list mailing list submissions to pd-list(a)iem.at To subscribe or unsubscribe via the World Wide Web, visit http://lists.puredata.info/listinfo/pd-list or, via email, send a message with subject or body 'help' to pd-list-request(a)iem.at You can reach the person managing the list at pd-list-owner(a)iem.at When replying, please edit your Subject line so it is more specific than "Re: Contents of PD-list digest..."

PixelTango builds on top of Gem, so there is no realy difference here. (i don't think that PixelTango comes with an abstraction for Gem that does right out-of-the-box what you need) chris clepper wrote: > You need one value for each pixel row in an image? That will probably > require writing a custom external to do that. not necessarily. if you have plenty of cpu left, you could go for Gem's [pix_dump], which dumps the entire image as a list into "pd-space". then you can do whatever you want with it (e.g. use iemmatrix to calculate what you need). another solution with Gem might be to use [pix_resize] with a width of 1 and then [pix_dump] the image "column". other libs: i am sure there are some simple resizing mechanisms in GridFlow. if you need to do more complicated stuff on the data, GridFlow might be a good choice anyhow, since you could stay in grid-space rather long and only do the conversion into pd-space at the very end. pdp/pidip: i don't know, but i am sure there are solutions here too. so it really depends on what else you want to acchieve. if it has to run on w32, then the solutions are limited.

Hi List! I would like to process a live recording video with pure data. I need to extract bright information of each horizontal video line but I don't know if there is any external which do that. Which external or library (GEM, PixelTango, ...) do you recommend me to process video? Thanks! -- Raul Diaz Poblete ************************* raul.lete(a)gmail.com Ciudad Real [Spain]

Hi Ico, I had a veeery big breath before start compiling flext/stk & munger1~ :-). Unfortunately I had the same results as Kevin on Win32 (cygwin): ... [lots of compilation stuff here] ... /usr/lib/gcc/i686-pc-cygwin/3.4.4/../../../../i686-pc-cygwin/bin/ld: cannot find -lstk collect2: ld returned 1 exit status make[1]: *** [pd-cygwin/release-shared/libflext-pd.dll] Error 1 make[1]: Leaving directory `/cygdrive/d/zin/my_install/flext' make: *** [build-release-shared] Error 2 Note: I got successful compilation of flext without stk, the previous error was obtained by compiling flext against stk. I definitely need more time to understand the flext/stk stuff before going into munger1.. I'll let you know if I'll be able to get it.. All the best, Alberto Zin http://puredata.org/Members/AlbertoZ
