call for help: help patch fixing
by Hans-Christoph Steiner 02 Mar '09

02 Mar '09

Hey all, A while back, I wrote some scripts that can automatically load every help patch and load every objectclass. I would like to set these up to run every night, but I don't think I'll be able to keep up with the output from this, i.e. fixing the help patches that crash and at the same manage getting this Pd-extended 0.41 release finished. So I want to see if there is anyone willing to handle this whole process. I think it will make Pd much more reliable if we can track down the little errors in help patches that can cause crashes. As far as I am concerned it can be managed how ever anyone wants to do it. I have these basic scripts ready to go, but they could easily be replaced with something else, if anyone else wants to do that. I think this could then be expanded into a broader testing framework. .hc ---------------------------------------------------------------------------- 'You people have such restrictive dress for women,’ she said, hobbling away in three inch heels and panty hose to finish out another pink- collar temp pool day. - “Hijab Scene #2", by Mohja Kahf

strange wave
by Hans Roels 02 Mar '09

02 Mar '09

Hello, Sometimes when I record audio in Pd, a wave file is created that Pd can't open or play. If I try to open this wave file in an other audio program like Audacity, this is also impossible. VLC player does play the file though and when I open this file in Samplitude a message "file does not contain sample data" appears but I can open the file. If I resave it in Samplitude it can be opened in Pd. I guess something is wrong in the headers of the wave file that Pd creates. In attach is a short example of such a 'strange' wave file. I hope that somebody can see what is wrong in this file... There is still something very 'shaky' in the 'writesf~ ' object in Pd, I guess about 25% of the times I try to record something, I have this kind of problem. An other problem that sometimes occurs is that only a file with a name is created but without actual sampledata (and this isn't caused because I don't leave any time between the 'open' and 'start' command for 'writesf'). I haven't succeeded in isolating the exact problem yet but I'm trying... (I think it has something to do with using 'writesf' in an abstraction). I 'm working on Windows XP and this problem occured in Pd 0.40.3 and in 0.42-4. Hans R

Building 64bit pd-extended on Ubuntu Intrepid
by danomatika 02 Mar '09

02 Mar '09

After much playing around, I managed to build a pd-extended 64bit .deb for Ubuntu Intrepid. I put all of the steps on the pd-wiki: http://puredata.info/docs/developer/BuildingPdExtended64bitUbuntuIntrepid It's not a true pd-extended as the 0.41 version seems to still have the table bug, but now I can use my new computer for pd-age. --- Dan Wilcox danomatika.com robotcowboy.com

new Ubuntu builds: Jaunty/i386 and Netbook Remix/lpia
by Hans-Christoph Steiner 01 Mar '09

01 Mar '09

I just figured out the magic of chroot and debootstrap so now there are two more builds: ubuntu-jaunty-i386 and ubuntu-hardy-lpia. "lpia" is Low-Powered Intel Atom, and it is the architecture for Ubuntu's Netbook Remix distro. You can get these builds in the usual place, whenever they successfully build: http://autobuild.puredata.info/auto-build/latest/ If anyone is interested in setting up multiple Fedora build environments, let me know and I can get you what you need to set things up on the Fedora box in the build farm. .hc ---------------------------------------------------------------------------- I spent 33 years and four months in active military service and during that period I spent most of my time as a high class muscle man for Big Business, for Wall Street and the bankers. - General Smedley Butler

OT Internet in the south of France
by Dafydd Hughes 01 Mar '09

01 Mar '09

Hi folks Can I pick the brains of my European friends? We're spending the month of May in Six-Fours in southern France (not far from Marseille I think). Just found out that I may need to keep working while we're there and I'm trying to find out what my options are re: internet access. I believe the house we're staying in doesn't have a phone, so definitely no internet. Can anybody suggest a solution? Is there a wireless or mobile internet option? Am I best to just get a hotspot subscription? (sorry this is so OT) cheers dafydd -- www.sideshowmedia.ca skype: chickeninthegrass

Google Summer of Code 2009!
by Hans-Christoph Steiner 01 Mar '09

01 Mar '09

Hey, Google is doing summer of code again, this time we have the knowledge and an app so that we can get chosen again. Here's the site: http://code.google.com/soc/ Here's our app from last year: http://puredata.info/dev/summer-of-code/ The first question to answer is: are all of the mentors from last year still up for being a mentor this year? The mentor gets $500 per student, perhaps being a mentor would be more enticing if the mentor got to keep the $500. Here's the list from last year: IOhannes? m zmoelnig umlaeute AA gmail.com Damian Stewart damian.stewart AA gmail.com Hans-Christoph Steiner pdgsocmentor AA gmail.com Jamie Bullock jamie.b.bullock AA googlemail.com ClaudiusMaximus? clodmax AA googlemail.com Andy Farnell andyfarnell AA googlemail.com Alexandre Castonguay anaxel.guy.de.tarascon AA gmail.com Bryan Jurish moocow.bovine AA gmail.com Chris McCormick? mccormix AA gmail.com David Plans Casal davidplans AA gmail.com B.

fractional delay for PD
by David Doukhan 01 Mar '09

01 Mar '09

Hi all, I'm trying to use a variable fractional delay in one of my patch. I've tried to use vd~ , but was not really convinced by the results I obtained. It seems I need a better method. Does anyone knows other PD external that could implement fractional delay with variable delay length? By the way: I'm tring to have a look at the litterature related to that subject... I don't even know what method have been used in vd~ ... The only thing I've read in the corresponding help patch, is that the interpolation method used by that component does an interpolation over 4 values. Does anyone know the name of the method used by that component? It would allow me get better clues on its theoretical efficiency, and to know if spending some time to program/test some alternative method would be usefull... Any help would be appreciated. Thanks! -- David Doukhan

string2any in arduino.pd is now broken
by Hans-Christoph Steiner 01 Mar '09

01 Mar '09

So I have been happily using the string2any object in my arduino object and it works well. But it seems that something has changed, and it now causes a freak out on load: string2any_setup(): WARNING: names are in flux! string2any_setup(): Prefer [bytes2any] over [string2any]. bytes2any: pdstring version 0.09 by Bryan Jurish moocow/string2any: already loaded ... snip (repeat 1000 times) ... moocow/string2any: already loaded error: maximum object loading depth 1000 reached moocow/string2any 32 -1 ... couldn't create [arduino]: version_0.4 This is with pd-extended 0.41.4 20090209. This works fine in Pd- extended 0.40.3. .hc ---------------------------------------------------------------------------- 'You people have such restrictive dress for women,’ she said, hobbling away in three inch heels and panty hose to finish out another pink- collar temp pool day. - “Hijab Scene #2", by Mohja Kahf

structuring of pd objects (was: Re: [PD-dev] stripping down Pd-extended's default libs)
by marius schebella 01 Mar '09

hi, (maybe this is of general interest for pd users?) speaking of lists, I once did a similar thing some years ago, collecting 2682 objects. the list is far away from being complete or up to date... http://www.parasitaere-kapazitaeten.net/files/GENERAL_ALL.csv_.txt marius. 2009/2/20 João Pais <jmmmpais(a)googlemail.com>: >> Hans-Christoph Steiner wrote: >> I definitely agree that we should have libraries organized based on a >> topic.
