pd-extended on ubuntu intrepid: troubles
by Athos Bacchiocchi 03 Mar '09

03 Mar '09

hi, I installed pd on ubuntu intrepid from official repositories through installer manager, and everything worked fine. After, I needed pd-extendend so I went on the pd website and I downloaded the pd-extended contributed build for intrepid, at: http://pd.ianagnostopoulos.postgrad.shef.ac.uk/pd-extended_0.40.3-intrepid6… After installing the package, I noticed that pd seemed to have disappeared (of course if I install it again from repositories, it appears again and works, but it's not pd-extended... and every time I try to install again pd-extended I have the same trouble). There's something I miss? thanks, athos

Your debug approach is commendable Hans. Notice that the EOF is different. It's not a well formed file unless eof works. The problem, as stated by another poster, is that the file appears zero length. Mike The errors are caused by bad message ordering in the patch. I have highlighted where they are, and suggested some corrections (use triggers) Please be thoughtful of posting in the right thread (It's okay to start a new one) a.

SQLite3DBv0.03
by Mike McGonagle 03 Mar '09

03 Mar '09

Hello all, I would like to announce the release of SQLite3db. This release represents a complete rewrite of the externals. It has been rolled into a single external library containing the externals [sqlite3db], [sqlite3query], [sqlite3rowid], and [sqlite3blob]. This release includes several features: 1. Database can be on disk or an in-memory database. 2. The [sqlite3query] object now supports Place Holders. 3. Comprehensive error reporting. 4. Includes a separate object for retrieving the ID for the last record inserted (allows making links between tables) 5. SSSAD plug-and-play panel for storing multiple sets of SSSAD parameters. You can get the archive for files at: http://puredata.info/Members/mjmogo/SQLite3db_v0_03.zip/view Also, the 'makefile' only contains a process for making a 'pd_darwin' external for the Mac. It should not be difficult to compile for Unix or Windows, as it is Ansi-C. Everything should work with Vanilla Pd as well. Let me know if you have any suggestions, criticism, or general praises ;) Mike -- Jean-Luc Godard - "To be or not to be. That's not really a question."

Arduino/SRF05
by Dafydd Hughes 03 Mar '09

03 Mar '09

Hi folks I'm wondering if anybody can point me at an example of using Pduino and an SRF05 ultrasonic ranger? Not sure how to get the microsecond intervals needed. Apologies if this is covered elsewhere on the list or if it's just a stupid question. cheers dafydd -- www.sideshowmedia.ca skype: chickeninthegrass

[arduino] object & analog inputs
by glerm soares 03 Mar '09

03 Mar '09

Hallo, I know this maybe too hardware concern issue, but since I am testing the new firmata with the [arduino] object, and maybe this could interest other users, I think this could be a topic of interest. My doubt is: how to get a *totally* not flickering analog input with more than 64 steps? I always had the flickering problem even putting other pins to the ground... generally I do [inlet] | [/8] | [int] | [change] | [outlet] I use 10k potentiometers, without resistors in the input... Does anyone get this input without any flickering? what's the secret? thanx glerm

If that version had table issues, then please submit a bug report and example patch to the bug tracker. 0.41.4 should work fine on 64-bit. I am cc'ing the list since you'll have better luck there.

[PD-announce] Taller de Algoritmia Marzo 2009
by Correa Diego 03 Mar '09

03 Mar '09

Taller de Algoritmia Informática Aplicada a las Artes. Técnicas en programación audiovisual con Pure Data y MaxMSP*. Resumen: La orientación del taller es la integración de conocimientos prácticos de programación visual para la formulación de micro-proyectos audiovisuales/acústicos/musicales haciendo uso de la herramienta Pure Data (Pd)*. Durante cuatro sesiones se tratarán de forma representativa y práctica los temas de instalación, uso y dirección de la herramienta Pd al control lógico de métodos básicos en audio y video. Al integrar los métodos, los participantes deberán imaginar un cauce de acción con la interfaz lógica de Pd, para aplicar y formular alternativas en torno a las formas disponibles para la realización concreta en base a estructura, función y experiencia acústico/visual. Todo esto se resumirá en una obra que será debatida en grupo. - Fecha: 9, 16, 23 y 30 de marzo. - Horario: 16:00 a 17:30 hrs. - Lugar: dōjō 道場. Valenzuela Castillo 1269-B, Providencia, Santiago. - Información e Inscripciones: al correo algoritmia(a)labormedia.cl o al teléfono (562) 880 54 76. http://www.labormedia.cl/algoritmia Sobre el expositor guía: diego correa t. ha promovido una profunda curiosidad por las plataformas que dan pie a proyectos relacionados con la concepción y experimentación tanto en música y arte como en matemáticas. desde los inicios en 2003 del trabajo en modelado de agentes con programación convexa, mientras era alumno de economía, su interés por el uso de herramientas para el modelado matemático se ha desarrollado. en 2004 en el Centro de Música y Tecnología (CMT), actual Laboratorio Arcis de Informática Musical (LAIM), en santiago de chile, se instruyó para el aprendizaje por medio de software libre en interpretación musical y multimedial desarrollado en el instituto de investigación y coordinación acústica/musical (IRCAM) de francia. entre el 2006 y el 2008 desempeñó labores de producción e investigación para el Laboratorio de Medios de la Universidad Católica de Chile (MDLB UC), fundado por el neurobiólogo y artista de medios de la Universidad de Nueva York (NYU), José Miguel Tagle. desde entonces ha estado desarrollando modelos de adaptación de herramientas digitales al uso en áreas no solo matemáticas y acústico/musicales, sino también en economía, cibernética, inteligencia artificial, neurociencia teórica y teoría de la información.

OT: job offer with requested pd programming skills
by Lao Yu 02 Mar '09

02 Mar '09

Hi, I just came across the website of 'reactable systems' in Spain - they're looking for a software programmer who has among others C++ and pd programming skills http://www.reactable.com/join.html Interesting that they require someone with pd skills - it makes one think that their system is if not pd based at least prototyped in pd. Best Jurgen
