Re: [PD] [hid] on linux
by Hans-Christoph Steiner 20 Dec '07

20 Dec '07

Hey, Please keep this on the list, there are a number of people that can answer these kinds of questions and the response might be of interest to others, and useful to have in the archives. On GNU/Linux, [hid] uses the input.h /dev/input/event* interface. Any device that is supported by the Linux input event system and has a /dev/input/event* device will work. .hc On Dec 18, 2007, at 1:11 PM, jean-martin barbut wrote: > HI, > > Thanks, it worked.

Fwd: What exactly is a "stack overflow" ?

It is NOT to fix a FEATURE of PD, but to give warnings as what NOT to do to shoot yourself in the foot. If you know NOT to connect up a [bang( -> [until] without some sort of termination means, then you won't do it... Or if you really need to experience it first hand, then by all means do it. You probably will never do it again... Besides, this object is so old that to make a change like this would probably break a large portion of PD patches that use [until]. Mike

file system for pd
by Timmy 19 Dec '07

19 Dec '07

hi everyone, is there a similar object to the coll object in pd ? im trying to save preferences for a patch.. is this possible ?? also does anyone know of a way to have a specified folder preselected in the "openpanel" object.. at the moment it always opens in the same dir as the saved pd file.. id like to create browsable folders/filesystem for selecting files whilst performing.. any ideas would be great.. ta! tim -- trws logo therhomworkshop.unit 60.spike island.133 cumberland road.bristol BS1 6UX t.+44(0)1179 221 558 m.+44(0)7971 007 707 e.mrtim(a)therhomworkshop.com www.therhomworkshop.com

looping a list
by altern 19 Dec '07

19 Dec '07

hi sometimes i get stucked on easy things like this while using PD, i guess because my head is too used to text programming... I need to loop a list of symbols. I have an arbitrary length list like |hi hola kaixo moi( and i need to be able to get the individual items to loop it. The idea is that given a list with sound/video files names, to be able to jump from one to the next when the prev has ended, and maybe come back to the first when all are played. i know this must be absolutely trivial but i just dont know where to start from. I havent done much work with lists in PD so far. thanks enrike

general "wacom" device with [hid]?

Hello, Is there a way to use the /dev/input/wacom symbolic link (which is automatically created to point to the correct event*) with [hid]? I am still using [linuxevent] because it works this way and is very useful when having to unplug/replug in the wacom tablet. best, rich

hi list im currently working on a patch that should be simple 4 channel mixer with 2 return channels for FX the problem - pd cpu usage is roling around 10-15% but my gnome (and e-16) system monitor shows 60-70 % and it is from my patch. why there is this difference? does pd "load meter" and dsp~ from iem show only the pd cpu usage? is there a way to "fix" this? im on ubuntu studio cpu amd 2400+ Pd version 0.39.2-extended-rc4 thanx nikola -- www.echoplex-label.de/njeremic

xxxxx-workshops: [in]tolerance @ Club Transmediale
by Derek Holzer 19 Dec '07

19 Dec '07

xxxxx-workshops: [in]tolerance 29 Janaury - 2 February 2008 Club Transmediale Ballhaus Naunynstrasse, Berlin xxxxx-workshops: [in]tolerance presents a series of constructivist workshops specially programmed for the ClubTransmediale 2008 festival, emphasising making and connection within the field of the existent. Workshops are led by international, field-expert practitioners, extending over realms of environmental code, noise, signal transmission, reception, and electromysticism. The workshops will utilise household materials and chemistry, readily-available electronics components, free software and the GNU toolbase. Over the course of five days, participants will have the opportunity to construct a set of various electronic audiovisual artifacts (being either code or hardware) with which a final presentation/performance will be made. In learning how to create complex sound and image generators from the most basic elements, the participants will explore liminal electronic experiences and intriguing phenomena where carefully-engineered borders and parameters are twisted and transgressed, producing unexpected results in performance. Workshops: 29.1. NOISE_PRODUCE by Martin Howse (UK) & Martin Kunetz (DE) 30.1. ONE BIT MUSIC by Frederik Olofsson (SE) 31.1. DIGITAL THEREMIN WORKSHOP by Andrei Smirnov (RU) & Derek Holzer (US/NL) 01.2. CHAOS IN NODES AND NETWORKS by Jessica Rylan (US) 02.2. BASTARD NATURES by Alejandra Nuñes Perez (CL) The series takes inspiration from and continues the development of the (semi)weekly xxxxx workshops held at the Pickled Feet space in Berlin over the last year. It is supported by Arduino. Theme: "...in the good old days of Shannon's mathematical theory of information, the maximum of information coincided strangely with maximal unpredictability or noise..." [Friedrich Kittler: There is no software] Engineers and scientists are concerned with prediction and thus predictability. Inside black-boxed apparatus the faint markings of tolerance, deviations from a predictable scenario towards the encryption of noise, can well be observed by the wily artist. Technology is thus exposed as a material expressing a certain chaos, pure noise of all voices. In return, materiality and an artistic concern with the matter of technology allows for the entry of the unpredictable, environmental noise within an otherwise closed circuit or economy. Registration: xxxxx-workshops is open to anyone, from novice to experienced electronic artist. The workshops will be held in English. You can register for single workshops or for the whole series. In addition to the actual daily workshops, a free open work-area gives everyone opportunity to pursue projects begun in one of the workshops over the course of five days. The registration fee for a single workshop is 10.- EUR, the fee for the series of all five workshops is 30.- EUR. For descriptions of the workshops and workshop leaders go to: http://www.clubtransmediale.de/club-transmediale/xxxxx-workshops.html You can register till January 14, 2008, by sending an email to: xxxxx(a)clubtransmediale.de Please don't forget to indicate which of the workshops you wish to attend. xxxxx-workshops: [in]tolerance is curated by Martin Howse and Derek Holzer, and produced by Jan Rolf and Anke Eckhardt for Club Transmediale. -- derek holzer ::: http://www.umatic.nl ::: http://blog.myspace.com/macumbista ---Oblique Strategy # 139: "Revaluation (a warm feeling)"
