[PD-announce] Festival Rencontres Internationales Paris/Berlin/Madrid
by Jack 02 Dec '08

02 Dec '08

Hello list, For people in Paris during this week. There is the festival 'Les Rencontres Internationales Paris/Berlin/ Madrid' with the RYBN installation AntiDataMining (ADM). Adress : Theatre Paris-Villette Parc de la Villette Metro 'Porte de Pantin' 75019 PARIS It's free. The installation is developed with Pd/GEM/PHP/MySQL on 3 screens and 2 speakers. This is the first step of this project. EN : ANTIDATAMINING is based on the recovery and the viewing/visualization of web-extracted data. It aims at creating audiovisual environments written, fed and updated in realtime. The goal of this project is to make emerge and to identify, using the Data Mining processing, several social and economic imbalance “phenomenas”. ADM seeks to visualize these phenomenas, and to tries to establish a global imbalance cartography. FR : « Antidatamining » est un projet de recherche basé sur la récupération, via Internet, de données boursières et financières, ainsi que de nombreux indices socio-économiques. Ces données sont archivées et classées, puis sont ensuite soumises au traitement des algorithmes propres au Data Mining. Elles sont ensuite visualisées, au sein d’environnements audiovisuels écrits, nourris et actualisés en temps réel. Le projet vise à faire émerger et à prédire des phénomènes de déséquilibres socio-économiques, et tente de mettre en place une cartographie générale du déséquilibre. DE : „ANTIDATAMINING“ ist ein Forschungsprojekt, das auf der Wiederverwendung von Börsen- und Finanzdaten sowie zahlreicher sozioökonomischer Indizien aus dem Internet beruht. Diese Daten wurden archiviert und geordnet, dann einer für Data Mining typischen algorithmischen Behandlung unterzogen. Danach wurden sie innerhalb einer audiovisuellen geschriebenen Umgebung visualisiert, angereichert und in Echtzeit aktualisiert. Das Projekt will Phänomene sozioökonomischen Gleichgewichts aufkommen und vorhersagen lassen und versucht, eine generelle Kartographie des Ungleichgewichts zu konstruieren. ES : Antidatamining" es un proyecto de investigación en línea basado en la recuperación de datos bursátiles y financieros y también otros numerosos índices socio-económicos. Estos datos son archivados, clasificados y luego tratados mediante cálculos algorítmicos propios del Data Mining. Los datos seguidamente visualizados mediante escritos audiovisuales son alimentados y actualizados en tiempo real. El objetivo del proyecto es predecir y hacer emerger los fenómenos de desequilibrios socio-económicos, e intentar establecer una cartografía general del desequilibrio. ++ Jack _______________________________________________ Pd-announce mailing list Pd-announce(a)iem.at http://lists.puredata.info/listinfo/pd-announce

$0-messages
by Jaime Oliver 02 Dec '08

02 Dec '08

hello, I am working on a machine that isn't mine. a mac desktop 2 x 2.66Ghz intel machine. pd-0.41-4 The problem is that if i have a number box conected to an object [s $0-test] and a number box conected to an object [r $0-test] numbers are transmited ok. But when I send the message through a message box: ; $0-test 3 then it doesn't receive the 3 and it complains: error: 0-test: no such object. Now i have tried it in my laptop and it doesn't work either. Did this ever work???? I somehow thought it would! but I'm confused now... cheers, Jaime -- Jaime E Oliver LR joliverl(a)ucsd.edu www.realidadvisual.org/jaimeoliver www-crca.ucsd.edu/ www.realidadvisual.org 858 202 1522 9168 Regents Rd.

missing dependencies for pd-extended on ubuntu 8.10
by Ilias Anagnostopoulos 02 Dec '08

02 Dec '08

Hello Roman, I assume you tried downloading the package through HTTP. There is an info link next to the download, md5 and APT links on the download page, that links here: http://pd.ianagnostopoulos.postgrad.shef.ac.uk/notes.txt This describes the dependencies, and gives you another link, http://pd.ianagnostopoulos.postgrad.shef.ac.uk/pd-deps.tar which contains a tar archive with the three packages of the dependencies. If you try getting it through the OtherSide APT, the dependencies are there and thus automatically configured. These three packages have been removed from the official Ubuntu (and I think also Debian) repositories since no package there depended on them. My understanding is that they are NOT replaced by the ones you mentioned. I tried simply changing the dependencies to the newer versions and it installed, but came up with many errors when launching PD. GEM seems to need the specific versions it depends on. I think that since there is no "serious" reason not to use these libraries, it doesn't make sense doing anything to the source code to make it compatible with the newer versions. If we simply provide these extra packages with the PD package, by hosting them on the same places, it will be fine. Since nothing else has anything to do with them, they won't break anything. -Ilias

midiout
by Yvan Vander Sanden 01 Dec '08

01 Dec '08

Hey Could it be there is something wrong with the implementation of [midiout]? I am using ubuntu linux, with 0.40-3 extended. I have input from [cyclone/seq] which prints out fine, but the [midiout] object does not seem to react on this. I use alsa-midi, btw. With a 4 port output device. I have made midi files for each separate port, since midiout does seem to expect that, but that did not help one bit.

Pdpedia Chinese
by chun＠goto10.org 01 Dec '08

01 Dec '08

Hi all: I have recently met many enthusiasts here in the far east, and as a result, we would like to start a project translating Pdpedia into Chinese (probably traditional chinese first, then simplified a bit later). This project is helped also by GOTO10, where we have a mailing list called pdtw. if you are interested in taking part in the project, feel free to get involved and sign up:) the list is here: http://lists.goto10.org/cgi-bin/mailman/listinfo/pdtw As a result, I would like to put in a request for getting the SysOp access on the wiki. cheers chun

Speaker protection abstraction
by Spencer Russell 01 Dec '08

01 Dec '08

Most of my live performance work involves realtime processing of upright bass, and I find myself often using a lot of very short variable IIR taps (delays with feedback). I use either my 500-watt bass amp or the house PA as output. Right now I don't have any explicit patchage to make sure I'm not pumping out any signal that's straining the amplification system, and if I watch my speakers as I play I often see them popping in and out in a distressing fashion. I'm thinking I should start including some basic speaker protection into the output stage of my patches, mostly a limiter and highpass filter to get rid of any sub-audio and DC signal. Is this necessary? I assume that either the output of the firebox or the input of my amplification setup is AC-coupled and should be getting rid of DC anyways, but we all know what happens when you assume. Are other people using speaker protection patches? Anything more sophisticated than the classic [hip~ 5] before the output? -spencer

$0 and Data Structure Templates
by Luke Iannini 01 Dec '08

01 Dec '08

Hallo all, I'm working on my complex DS sequencer, and the time has come that I'd like to read and write sequences from it. The problem is this: all of my templates are written like [pd $0.note-template] to allow multiple instances of the sequencer, but this seems to be incompatible with reading and writing data from a subpatch ( like [write my-data.structure( - [pd $0.data] ), because the $0 is expanded in the written file (so it's full of "template 90953loopMarkerTemplate;" etc. rather than "template \$0loopMarkerTemplate;"). The immediate thought was to split the templates into a separate patch altogether, and spawn it before creating the sequencer or use a singleton approach. But, this ruins using [change( messages from [struct]s as well as selectively turning on and off [draw*]n elements on a per-sequencer basis. The only other option AFAICT is to forget DS reading and writing and just mirror the data in lists with SSSAD, but that would be a shame considering the capability exists already. It seems to me that the written datastructure definition should preserve $0, no? Anyone have any other ideas? (apologies if this is unclear, I'm very tired at the moment) Best Luke

missing dependencies for pd-extended on ubuntu 8.10
by Roman Haefeli 01 Dec '08

01 Dec '08

hello all, hi ilias i tried to install the ubuntu intrepid package of pd-extended on a ubuntu intrepid machine and got missing dependencies. pd-extended is dependent on the following packages, that seem not to be part of intrepid: libmagick++9c2ca libmagick9 libmpeg1 i guess, those can be replaced by the folling packages, that are part of the intrepid repository: libmagick++10 libmagick10 libmpeg3-1 i haven't thorougly checked, if those are suitable replacements. if not, probably someone else can suggest the correct ones. would it be possible to install those packages on your intrepid machine and compile pd-extended against those? roman p.s.: it seems you already found a temporary substitution for your broken server. i am running a debian stable (currently 'etch') server and i could provide you an account. however, i don't know, if a debian box helps you at all. if you think, it would, please let me know. ___________________________________________________________ Der frühe Vogel fängt den Wurm.

Pd/GEM crashing in fc8
by Jaime Oliver 01 Dec '08

01 Dec '08

Hello all, I have found a new problem in my machine with Pd and the recent changes i made: (I mentioned them in a previous e-mail, but I'll restate them: installing recordmydesktop and Mplayer, and adding support for mpeg3, Quicktime and ffmpeg, then recompiling gem) Now this is what I can see so far: everytime I: -change an object's name while pd is running, -copy part of a patch into another patch, I get the following message in the terminal: *** glibc detected *** ./pd: malloc(): memory corruption: 0x0000000000fa56a0*** (below is another one with more details) pd is looks ok, but I can't use any of the menus or edit and need to quit it from the terminal with ctrl+c. If there is a gem window then it is impossible to quit. If I reopen pd I get the following message and no sound of course: snd_pcm_open (input): Device or resource busy snd_pcm_open (output): Device or resource busy I then need to restart the machine to get sound again. At this point, I think it only happens with patches that have a gemwin... below is a longer error message after closing a patch and opening it again. Anyone have a clue of what could be causing this and how to solve it? cheers, Jaime *** glibc detected *** ./pd: malloc(): memory corruption: 0x000000000165c530 *** ======= Backtrace: ========= /lib64/libc.so.6[0x3470272fec] /lib64/libc.so.6(__libc_malloc+0x7a)[0x34702748fa] /usr/lib64/libstdc++.so.6(_Znwm+0x1d)[0x34840bd1ed] /home/joliverl/Desktop/Gem/src/Gem.pd_linux(_ZN11pix_filmNEWC1EP7_symbol+0x1d9)[0x92d9b9] /home/joliverl/Desktop/Gem/src/Gem.pd_linux[0x92db33] ./pd(pd_typedmess+0x46e)[0x45d4ce] ./pd(binbuf_eval+0x47d)[0x461aed] ./pd[0x419da6] ./pd(canvas_obj+0x70)[0x41bb30] ./pd(pd_typedmess+0x287)[0x45d2e7] ./pd(binbuf_eval+0x47d)[0x461aed] ./pd(binbuf_evalfile+0xae)[0x466c0e] ./pd(glob_evalfile+0x1c)[0x466ccc] ./pd(pd_typedmess+0x389)[0x45d3e9] ./pd(binbuf_eval+0x47d)[0x461aed] ./pd(socketreceiver_read+0xecb)[0x46fe4b] ./pd[0x46cfb4] ./pd(m_mainloop+0xa5d)[0x46965d] ./pd(sys_main+0x120b)[0x46c8ab] /lib64/libc.so.6(__libc_start_main+0xf4)[0x347021e074] ./pd[0x40ffd9] ======= Memory map: ======== 00110000-001ac000 r-xp 00000000 fd:00 18513989 /usr/lib64/libavformat.so.52.22.1 001ac000-003ac000 ---p 0009c000 fd:00 18513989 /usr/lib64/libavformat.so.52.22.1 003ac000-003b7000 rw-p 0009c000 fd:00 18513989 /usr/lib64/libavformat.so.52.22.1 003b7000-003b9000 rwxp 00000000 00:0f 203 /dev/zero 00400000-004e0000 r-xp 00000000 fd:00 33622022 /home/joliverl/Desktop/pd-0.41-4/bin/pd 006e0000-006e2000 rw-p 000e0000 fd:00 33622022 /home/joliverl/Desktop/pd-0.41-4/bin/pd 006e2000-006ef000 rw-p 006e2000 00:00 0 006ef000-00a25000 r-xp 00000000 fd:00 33591301 /home/joliverl/Desktop/Gem/src/Gem.pd_linux 00a25000-00c24000 ---p 00336000 fd:00 33591301 /home/joliverl/Desktop/Gem/src/Gem.pd_linux 00c24000-00c49000 rw-p 00335000 fd:00 33591301 /home/joliverl/Desktop/Gem/src/Gem.pd_linux 00c49000-00c4e000 rw-p 00c49000 00:00 0 00c4e000-00c7b000 r-xp 00000000 fd:00 18513967 /usr/lib64/libmpeg3.so.1.0.0 00c7b000-00e7b000 ---p 0002d000 fd:00 18513967 /usr/lib64/libmpeg3.so.1.0.0 00e7b000-00e81000 rw-p 0002d000 fd:00 18513967 /usr/lib64/libmpeg3.so.1.0.0 00e81000-00e94000 rw-p 00e81000 00:00 0 00e94000-00f18000 r-xp 00000000 fd:00 18513997 /usr/lib64/libquicktime.so.0.0.0 00f18000-01117000 ---p 00084000 fd:00 18513997 /usr/lib64/libquicktime.so.0.0.0 01117000-0111c000 rw-p 00083000 fd:00 18513997 /usr/lib64/libquicktime.so.0.0.0 0111c000-0111d000 rw-p 0111c000 00:00 0 0111d000-01161000 r-xp 00000000 fd:00 18513933 /usr/lib64/libmp3lame.so.0.0.0 01161000-01360000 ---p 00044000 fd:00 18513933 /usr/lib64/libmp3lame.so.0.0.0 01360000-01362000 rw-p 00043000 fd:00 18513933 /usr/lib64/libmp3lame.so.0.0.0 01362000-01393000 rw-p 01362000 00:00 0 01413000-01b65000 rw-p 01413000 00:00 0 [heap] 0364f000-0365d000 r-xp 00000000 fd:00 18513981 /usr/lib64/libfaac.so.0.0.0 0365d000-0385d000 ---p 0000e000 fd:00 18513981 /usr/lib64/libfaac.so.0.0.0 0385d000-03860000 rw-p 0000e000 fd:00 18513981 /usr/lib64/libfaac.so.0.0.0 03c21000-03c29000 r-xp 00000000 fd:00 18513991 /usr/lib64/libavutil.so.49.10.0 03c29000-03e29000 ---p 00008000 fd:00 18513991 /usr/lib64/libavutil.so.49.10.0 03e29000-03e2a000 rw-p 00008000 fd:00 18513991 /usr/lib64/libavutil.so.49.10.0 03e2a000-03e2d000 rw-p 03e2a000 00:00 0 04138000-04142000 r-xp 00000000 fd:00 18513965 /usr/lib64/liba52.so.0.0.0 04142000-04341000 ---p 0000a000 fd:00 18513965 /usr/lib64/liba52.so.0.0.0 04341000-04342000 rw-p 00009000 fd:00 18513965 /usr/lib64/liba52.so.0.0.0 04342000-04343000 rw-p 04342000 00:00 0 04380000-04Pd: signal 6 -- Jaime E Oliver LR joliverl(a)ucsd.edu www.realidadvisual.org/jaimeoliver www-crca.ucsd.edu/ www.realidadvisual.org 858 202 1522 9168 Regents Rd.
