Double File Open
by Samuel Burt 12 May '10

12 May '10

With Pd 0.42.5-extended-20100508 in Mac OS 10.5.8, I am seeing a weird bug. When I double click a *.pd file in the Finder, Pd opens two copies of the file, sometimes. I haven't noticed a pattern, yet, and I don't think I am triple clicking, either. I think it might only happen when double-clicking the file launches Pd, and not when Pd is already open. Has anyone else noticed it? Sam

[DTW] Dynamic Time Warping in Pd?
by Pedro Lopes 11 May '10

11 May '10

Hello, I'm trying to do a small project, for which I need an implementation of the DTW [1] (Dynamic Time Warping) algorithm. It takes to series of values and measures the similarity between them, considering that they can vary time or speed. I've done a few searches but seems to be impossible to find a DTW external for Pd, is there one? On the SMC2009 conference, a paper[2] was presented where they stated that they used DTW under Pd but I couldn't find their implementation anywhere (nor received feedback from the authors still). Also there is a reference to a Max/MSP implementation by Olaf Matthes [3] but once again... cannot find a Pd version. So if anyone can be of help in this search for DTW inside Pd, it would be most helpful. p.s.: As far as C alike implementations, I found this in C [4] and this C++ lib [5] seems to use a DTW implementation too.

pd-extended recent autobuilds
by Michal Seta 11 May '10

11 May '10

Hi all + Hans, I just installed pd-extended (0.42.5 build of april 30 2010) on a new machine to discover that it is now called pdextended and it does not show up in the applications menu (should I report a bug somewhere?) and that pdsend is missing. Is pdsend/pdreceive being phased out? Are these changes documented somewhere? -- ./MiS

message ordering with send
by Alexandre Porres 11 May '10

11 May '10

hi there, quick question, say I got a [send] object and many pairing [receive]... how do you predict the ordering of messages, or can't you do it at all? Meaning, which receive will actually receive the data first? The one that was first connected? My hint is that you have no way to control this cheers Alex

rdz PPA
by Martin Eckart 10 May '10

10 May '10

I'm trying to compile pd-extended from source (on Lucid amd64) and want to be sure that gmerlin is compiled into GEM. I came across Roman's ppa at https://launchpad.net/~reduzierer/+archive/rdz-pd-extra +deps?field.series_filter=lucid but although I add it like any other, apt doesn't seem to update the packages from the ppa (if I run "sudo apt-get update | grep ppa" my other ppa's are displayed but not rdz). I've managed to download and install the individual packages from the web front-end but I thought I'd mention this issue on here. Maybe there's a configuration issue in the ppa for Lucid amd64? Maybe I did something wrong? Thanks for providing this btw! -martin

compiling flashserver in Linux
by Pedro Lopes 10 May '10

10 May '10

When compiling flashserver in Linux (with fresh download from SVN) I got two small errors. They are fairly easy to correct and the external works great (kudos to Olaf for this one!). I've posted a small fix here[1] and probably the sources on the SVN could be updated and committed to avoid the errors. My system: $ pd -version Pd version 0.41-4 compiled 00:27:04 Nov 7 2008 $ uname -a Linux 2.6.31-9-rt #152-Ubuntu SMP PREEMPT RT Thu Oct 15 05:01:14 UTC 2009 i686 GNU/Linux $gcc --version gcc (Ubuntu 4.4.1-4ubuntu9) 4.4.1 [1] https://puredata.info/Members/PedroLopes/flashserverLinuxFix Best regards, Pedro Lopes -- Pedro Lopes contacto: jazz(a)radiozero.pt website: http://web.ist.utl.pt/Pedro.Lopes
