PDDP Meeting Notes - Dec 6th 2005
by B. Bogart 11 Dec '05

11 Dec '05

*PDDP December 6th Meeting Notes* _Bottom-up vs Top-Down:_ * Everyone does learn differently * Bottom up can be too detailed without the big picture (boring implimentation) * Top-down lacks flexibility and the student never really understands all they are doing(lots hidden in abstraction) * High-level abstractions that are made to play with and easy to connect. These should be designed to "feel" similar to low-level PD objects. They are so well patched that they also serve as patch examples. * We should jump between top-down and bottom up. Each tut has two parts, a high-level part (play video) and a low-level part (metro sending messages to [play video] * Don't use an object without explaining it. Ideally don't use an object without hinting for its need in a previous example. * Each tutorial page should end with a question which a new object/concept on the next page answers. _Modules:_ * Image (video, still image, even canvas animation) * frame (still image or video frame) * effects (altering images) * generating images from scratch (graphics) * arrangement (placing media in time/space) * Sound (audio signals) * sample (load and play) * filtering (change sample) * synth (sound from sratch) * arrangement (combination of sounds) * Networks (communication, OSC, MIDI, internet etc..) * Physical Media (MultiIO, AID, Aurduino) _Project Based:_ * If the students are working towards a concrete goal then they are more likely to remember and be invested in the workshop content. * Should the students come up with a project idea first? or during the workshop? Maybe a short survey meant to inspire the students. _Primer:_ * Inspire Students creatively * Show them what is possible with PD (lots of examples) * Start to shape the examples of work into the workshop structure * Give time before the first class for them to propose an idea. * History (of electronic music, electronic art, electronics, free software?) * What kind of tool is PD? _Creative Process:_ (I'm not sure where this fits into the structure) * Conceptual development of projects * Why PD? * Relationship between the tool and the concept (metaphorical networks) * There are always multiple ways of approaching a problem or process * Any technology embeds culture. It is made under certain assumptions. _Focus:_ * Respond to the students' need. (every group will have different interests) * Make the curriculum modular so that each piece fits with a particular audience. Then the students and the instructor choose which modules they want to cover. _Homework:_ * Students should be encouraged as much as possible to play after, during and before the workshop. Play with ideas and implemnentation of those. * The workshop should not assume homework, but it should be made clear the students best change of learning is by doing. _Links:_ http://arduino.berlios.de/ _Final Note from Hans_ "I just wanted to say one last thing, in case it wasn't clear, and that is that my main focus in this project is the idea of applying the ideas of open source development to the workshop materials so all of us can do less work and come up with better materials. I don't think its anyone's intention to force people to teach Pd in any certainway, we just need to be on the same page in order to cooperate" Next meeting will be at the same time in one week, Dec 13th.

GEM, fress CVS compile prob
by august 10 Dec '05

10 Dec '05

hey Y'all, I just checked out a fresh CVS version of GEM and compile breaks (under linux at least) when compiling 'Controls/gemframebuffer.cpp' looking for GL_TEXTURE_RECTANGLE_EXT a quick fix was to add: #include "Base/GemPixUtil.h" to 'Controls/gemframebuffer.h' -august. ------------------- http://aug.ment.org

Bug in spot_light?
by Frank Barknecht 10 Dec '05

10 Dec '05

Hi, playing around with Gem's spot_light I had a hard time to figure out, where the spotlight was looking until I found, that the cone used to visualise the light's position in "debug 1"-mode seems to point into a wrong direction. According to the screenshot in Pierre-Olivier Charlebois' thesis [0], the cone should point into the direction, the light is facing, however in my Gem (CVS couple weeks ago) it is pointing perpendicular to that. Attached patch should illustrate what I mean. Is this intended or do I just need new glasses? ;) [0] One line: http://www.epierre.ca/work/research/documents/Representing%20Sound%20-%20Ch… Ciao -- Frank Barknecht _ ______footils.org_ __goto10.org__

The Party at the Center of the Universe
by Pall Thayer 10 Dec '05

10 Dec '05

New work: http://pallit.lhi.is/tpcu/ The Party at the Center of the Universe is an attempt at using data generated by the public to generate a spatial construct on the internet. This spatial construct takes into consideration the user's position in space, orientation in space and identity. Each of these factors will affect the way a person is represented in the constructed space. A user's position is determined by reading the strength of their wireless network connection. A user's orientation is determined by reading the values of the accelerometer (Sudden Motion Sensor) built in to their laptop. A user's identity is determined by reading the username of the user currently logged on to the laptop. The readings are made by a downloadable Dashboard widget and does not depend on the user's concious interaction. It runs in the background, transmitting the necessary information to the party at 5 second intervals. It does not interfere with normal use of the computer and the user is free to shutdown the widget at any time if they wish (but it's more fun to know that even though you're in the middle of an important board meeting or giving a presentation to people who hold your destiny in the palms of their wallets... er... hands, you're also the life of The Party at the Center of the Universe). Hubbles law describes how every point in space sees itself as the center of the Universe. Due to an effect similar to the Doppler effect experienced when an ambulance speeds past, the Universe appears to be expanding away from every point in space, in all directions. So a space that has the potential to be a single locative indicator of every point in space, must be the embodiment of the Center of the Universe... and we're throwing a party! BYOB, good company and music is provided. Due to the hardware requirements, the currently available client program will only run on recent models of Apple PowerBooks and iBooks. There are some laptops from other manufacturers with built in accelerometers, such as some of the IBM Thinkpads, but as I don't have one, I can't create the client. Anyone who does have one, is free to download the source material and make one. However, anyone can observe the infinitely expanding, curved spacetime of the Center of the Universe. -- Pall Thayer palli(a)pallit.lhi.is http://www.this.is/pallit

So, a cluster of several computers (maybe with pure-dyne) would be needed to make an accurate model, indeed... patco

There are two known reasons for the blue color observed in energetic objects in space: an high electrical stress, and a speed movement in our direction caused by doppler effect. I am wondering how it could be possible with peedee to make a simulation of our universe model. patco.

Any good data struct examples? & a wish...
by Ed Kelly 10 Dec '05

10 Dec '05

Hi List, On a plane ride, I fanally got around to learning a bit about the complex data structures. Does anyone have some good examples of how to use data structures? I am trying to sponge as much info as poss...with no shame! Also, is there a way to select the graphical objects with a mouse inside the data object? It would be really useful to have an identity for each object, to be reported when objects are selected (I could contrive it with Gem, but anyway...) ps, I got /pipermail/pd-list/2005-08/030576.html already Best, Ed -> -> --> ---> -----> --------> -------------> r3search + praktik EK5perimenz --------------------------------- Yahoo!

hi hans, hi list ... i'm currently trying to get |hid| working with my usb keyboard ... first i have to say, that |hid| is working pretty good with the internal keyboard of my laptop ... but on my usb keyboard, i only receive data from the fancy multimedia keys (nextsong, mute, home, mail ...), but not of the normal keys ... the keyboard works fine, though (i'm currently writing with it) any idea, what might be the reason? thanks ... tim -- mailto:TimBlechmann@gmx.de ICQ: 96771783 http://www.mokabar.tk latest mp3: kMW.mp3 http://mattin.org/mp3.html latest cd: Goh Lee Kwang & Tim Blechmann: Drone http://www.geocities.com/gohleekwangtimblechmannduo/ After one look at this planet any visitor from outer space would say "I want to see the manager."

How to open a patch remotely
by Ed Kelly 09 Dec '05

09 Dec '05

Hi List, I'm trying to open a subpatch when the master patch loads. I have an abstraction in the master patch using GOP, and within that is a data window with some structures in it. Is there a message I can send like |; |pd-data open( that will open that window when the master patch is opened?

Max user thinking about PD
by eleacou＠yahoo.com 09 Dec '05

09 Dec '05

Hey guys, I am a regular user of MAX/MSP/Jitter and I was interested in learning more about PD and how it compares. If you guys get a moment I would love to hear any detailed info about PD. I really like how Jitter works with Video. Is there anything like this in PD? thanks. M.E.S. __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
