I never talked about using PD as a "general purpose" programming language. I talked about using it for what it totally rocks at, i.e. making interesting graphics and music, but doing it not only at a "prototyping level", that is not only making experiments and "small" patches, very difficult to extend, scale and mantain. Most of the missing features you mention would indeed be very interesting and desirable and make PD very powerful even just for "making interesting graphics music" and nothing else; however, I'm quite fine with the absence of them. What is frustrating is when, after learning the way PD works and developing your own strategies for building complex and scalable things with it, you find out that things stop working when you reach a "critical mass" (not justified in terms of real processing or memory "mass") because of bugs or implementation issues. Encapsulation; bottom-up or top-down design; modularization; reusability and parametrization. These are some of the criteria I apply when designing my patches, and I definitely don't think that is a philosophy inappropriate for a PD-like environment; I mean, I don't think I am trying to apply programming-language-coding concepts to a context where they are inappropriate. I think PD is conceived in a way that encourages those practices, and even rewards them with exciting results at the beginning (which further incourages one), but then suddenly betrays expectations on the long run. > Miller doesn't seem to be interested in turning > Pd into a general purpose programming language, which is probably a good > idea since it's so good at what it does already, and doing that might > ruin it completely. I agree with that. However, it's good at what it does already as long as you don't try to do the same things at a "bigger scale". > Long live Pd, the greatest and most fun audio visual mangling tool I > know of! Yeah, of course! That's what I hope. If I didn't, I wouldn't have written all this. -- Matteo Sisti Sette matteosistisette(a)gmail.com http://www.matteosistisette.com -- Matteo Sisti Sette matteosistisette(a)gmail.com http://www.matteosistisette.com

netclient [netclient]... couldn't create
by Agent Engram 11 Jan '08

11 Jan '08

History... 1. Building reactable 2. couldnt get CCRMA binaries to work on fedora, unknown cause, floating point error 3. built PD, PD working, but had problems with Gem 4. built Gem with lots of help from friends, Gem working 5. now wants all extended capabilities, especially all sound and networking to work well it seems as though even though Pd and Gem seem to work when I try to get my netclient loaded it fails and says something like ...couldn't create. do I need to build some more stuff? I want everything in extended to work. agent engram -- ----------- i am an agent implanted into your unconscious when you abducted by the travelers. look for signs of me in your life.

I not only experience the slowdown in that situation, but often even memory corruption or something: nonsense error messages such as ".x8972383 no such object" (or something like that: can't remember exactly), and sometimes some patch windows is closed that shouldn't be. Often the MAIN patch window is closed, i.e. disappears, so when I close any other open window, there's no open window left; then I quit PD and magically the main patch appears again, and it asks me whether to discard changes!!! (so I say "no" and that's the only way to have the patch appear again without quitting pd). All this happens when saving an abstraction which is used multiple times in an open patch... and in my case it's not hundreds of times but just tens of times. -- Matteo Sisti Sette matteosistisette(a)gmail.com http://www.matteosistisette.com

[OT] Bass driver unit
by PSPunch 10 Jan '08

10 Jan '08

Hi all, I would first like to apologize that this is totally unrelated to Pd. However I figured that this list is the most likely place to find an answer among the communities I subscribe to. Years ago I used some driver units to playback super low frequencies, down from the inaudible up to probably 100Hz at most. It was more like a chunk of steel designed to mount on any surface expecting it to resonate. These units were also very inexpensive and ran for 10s or 20s of US dollars I think. Today when I search for driver units of such kinds, all I can find are ones which look more like speaker cones and not exactly what I recall. Does anyone know of where to look, or keywords pointing to such products? and hopefully places I can purchase them online? BTW, of course the goal is to drive some of these using PD, inspired by Roman's work using solenoids :) -- David Shimamoto

Re: [PD] gem: can't load library

i am on fedora here is what about said about build-essential: Definition: *build-essential*: Informational list of build-essential packages If you do not plan to build Debian packages, you don't need this package. Moreover this package is not required for building Debian packages. This package contains an informational list of packages which are considered essential for building Debian packages. is gem dependent on debian?

[psql] object hand-holding
by andy.graybeal＠casanueva.com 09 Jan '08

09 Jan '08

i installed postgresql, and got it running, created a user for myself, compiled [psql] from postlude (i'm using pd-extended from cvs). i opened up the psql-help file and started with the first instruction, and it created the database fine, i moved to the second command and get this error: psql: Action failed. PQresultStatus is PGRES_FATAL_ERROR i'm wondering where i can look for more information about what is going wrong, and what i can do to fix it. i think it would be wonderful if i could start using a database to store values :) -andy

Wiimote for OS X
by Phil Stone 09 Jan '08

09 Jan '08

Greetings, I was checking with Hans about his progress debugging the wiimote object for OS X, and he said he'd be happy to get it working, but doesn't have a Wiimote to debug against. Someone had promised to send him one, but then apparently forgot about it. While I can't afford to send Hans a Wiimote outright, I'd be happy to chip in...is anybody else interested in getting the Wiimote working for other OSs? If at least one other person will share the cost with me, I'll do it. Drop me a line, Phil Stone pkstonemusic.com
