Survey back online
by Andrea Mayr 17 Oct '02

17 Oct '02

Dear PD'ler I'm sorry to bother you again, but for the last little while our server was offline (our ISP in Germany changed IP's without telling us), so some of you might have tried to access the survey and found the server unavailable. I apologize for that. Now it's online again and may I ask you for a last time -- I promise :) -- to take the time to fill out the survey, I extended the deadline for another three days. I'm sorry for this hick-up and I hope my survey and the surrounding email have not been too intrusive. grtz. Andrea

First sketch of CVS build system
by guenter geiger 17 Oct '02

17 Oct '02

Hi, I have justed checked in the first sketch of what I think should be the future build system for the externals in CVS. Most of the externals build nicely, problems are: * externals that depend on additional external libraries I do not know how to solve this yet. Maybe I will provide some additional. special makefile targets for those. * should work for osx,win,irix and linux later, but only linux is implemented yet. Next thing will be windows, help appreciated with osx. If possible I would like to have one single makefile for each, in order to make it autobuildable. If you have a snapshot already on your harddisk, go to the externals directory and do a "cvs update -d" this should add a directory called build. Go to build/linux, do a "make -k". Before I start getting rid of the warnings that some of the external produce, it would be great if the respective developer can take a look. Would be great if all builds without warnings. The next big task will be how to organize the documentation. Guenter

Reminder: Call for participation in a pd-survey
by Andrea Mayr 16 Oct '02

16 Oct '02

Dear PD'lers, on October 8, I posted to the pd-list und pd-dev list a call for participation in an online survey concerning the dynamics of software development within the PD community. For background on the survey, please check my original message (http://www.iem.at/mailinglists/pd-list/2002-October/000840.html). By now, already thirty people have filled out the form. This is a very good response rate, thanks a lot to all of those who took the time. Of course, some more replies would be even better :). So if you have thought about participating but haven't done it yet, please do so now. It won't take more than a few minutes. Survey: http://oss.zsi.at login: pdsurvey pw: ppddpdpp I will leave the survey online for another three days, afterwards I will take it down. Once I have the survey results available, I will post an short announcment, so that you can see that your time was well invested, I hope :). If you have any questions regarding this survey, the research project that it is a part of, or anything else, don't hestitate to write me. grtz. Andrea

Portaudio with Jack on Linux
by Frank Barknecht 16 Oct '02

16 Oct '02

Hi, I just discovered, that the Portaudio team is working on a Jack backend for its library. A preliminary version seems to be in the devel branch on portaudio-CVS. As Pd already uses PA for its OS-X and ASIO support, it seems only natural to me, if Pd could use PA for Jack on Linux as well. This would remove the need to have different Jack patches around. So, did anyone here try Pd with Portaudio-Jack already? ciao -- Frank Barknecht _ ______footils.org__

MIDI scheduler
by Sukandar Kartadinata 16 Oct '02

16 Oct '02

Hi again, as I've been having a closer look at the scheduler, I was wondering about one thing: why does s_SGI.c call the MIDI functions in x_midi.c directly, while all the other implementations use the MIDI queue in s_unix.c just curious - not that I plan to implement MIDI, but me too has to schedule events.... Thanks, Sukandar also here's a copy of my last post which I sent to the wrong list (just in case someone only reads pd-dev...): I finally updated the gluiph to 0.35 as well as the newest TriMedia SDK, and basically everything's still working with a few noticable improvements. One of them is the faster handling of double precision floats, however it's still a software emulation and thus to be avoided. So of course I stick with my fractional phase implementation of osc~ and friends. Now, the disturbing thing was that I only learned today that floating point constants are treated as doubles unless they're suffixed with an F. For some reason I'd always thought that it's the other way around (i.e. doubles have to be tagged with a D), but the TriMedia Docu as well as MSDN tell me that the implicit double is ANSI compliant. So one F added to my osc~ implementation, and boom, 7x faster for the critical code section! So far so good - but after some browsing thru the pd source it seems there's lots of places where the F is missing but surely no double precision is intended/required. I assume for PCs this only causes a small performance hit as the FP ALU does doubles in hardware so there's only the additional memory access for the extra 4 bytes (if at all). OK, so I guess I have to find all those constants by hand and hit that F key. Bad enough. The real issue though is that I probably have to do it again once 0.36 becomes available. Which brings me to my actual question: Could I check out the latest version of the CVS, make my changes (which might affect a lot of files), commit them back to the CVS, and everything's fine for future releases? Or would this create a separate branch off of the standard release? Or does Miller have to decide for every change being made if it should be rolled into the standard release? Sorry if this sounds a little dumb to the CVS pros, but this version control stuff is all rather new to me. And maybe it's actually not so much the technical questions but the social/political ones, i.e. who decides what changes are valid. Thanks, Sukandar

spam from a modal dialog
by Krzysztof Czaja 15 Oct '02

15 Oct '02

hi devs, after 'bang'->[openpanel] is clicked, tcl complains about an invalid command name "e". Same with 'read'/'write'->[funbuff] of course. Being neither a tcl/tk fan, nor an expert, I have not investigated this other than checking that sending the message _after_ itemconfiguring the message box helps. What is really going on inside is beyond my understanding. I get this in linux with tcl/tk8.3. Krzysztof

cvs - Mac OS X commits
by Adam T. Lindsay 09 Oct '02

09 Oct '02

Hi PD-dev. Günter suggested I post after the changes I made to the pd core in CVS. I changed things along two lines: compile out-of-the-box for MacOSX, and some Mac-oriented gui changes. To help the devel_0_35 branch compile on MacOSX with a simple configure; make, I commented out the cabs() macro in m_pd.h (as per Chris Clepper's advice on 27 Sept 2002). I also added a -DMACOSX in extra/paf~/makefile, as it relies on an explicit platform definition. To help make the PD gui more mac-like, I changed the right button behavior so that it would actually pop up a menu with a real right-click (instead of a middle-click) or a control-click (to go along with MacOS guidelines). I also added a bit of AppleScript(!) to open html help files in the default browser. Mac-folks, please take a look at the devel_0_35 branch to make sure what I did was acceptible. (And hey, those jsarlo gui hacks look cool...) Best regards, adam -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Adam T.

[slightly OT] resources in linux
by Thomas Grill 09 Oct '02

09 Oct '02

Hi list, considering the support of bitmaps in flext_gui.... does there a concept similar to Windows/MacOS resources (strings, bitmaps, etc...) embedded into executable files exist in linux? Sorry if this is obvious but ... i don't know it.... greetings, Thomas

Call for participation on a pd-survey
by Andrea Mayr 08 Oct '02

08 Oct '02

Dear members of pd-dev, I'm writing to ask you to take part in an online survey which I developed as part of a larger study on different types of virtual work groups carried out by the Austrian Center of Social Innovation (ZSI) [1]. Within this project, my role is to provide a case study on open source software development. Having an artistic background myself (I graduated from the University of Applied Arts and worked with various cultural projects here in Vienna[2] and NYC [3]), a deep interest in open source software and knowing some of the Austrian list members personally, looking at the pd community was a natural choice for my case study. I hope you don't mind this. Over the last couple of weeks, I conducted a series of interviews (mostly f2f) with pd'lers to get a deeper sense of the history / practice of the pd project. In addition to this qualitative data, I would like to collect some quantitative data as well. This is were you and the survey come in. Please take a few minutes to look at it and fill it out :) Survey: http://oss.zsi.at login: pdsurvey pw: ppddpdpp The survey is designed to respect your privacy and will be open for the next ten days. After that, I will analyze the data and share it with you. I hope my results will be also of interest to you, it might provide you with some feed back on the dynamics/motivations of pd as a group that might otherwise be less accessible. I hope that will be a fair exchange for the time that I ask you to take to fill in this survey. If you have any further questions, please contact me directly. grtz.
