Re: [PD] Call for GSoC mentors! March 9th deadline!
Do you think a valid project would be to debug pd / pd-extended 64 bit builds? After losing a few days trying to get a solid 64 build of pd +externals, I'm a bit disappointed at the current state. It's something rather boring, but would be quite useful for the future ... the next OSX (Snow Leaopard), for instance will be natively 64bit.

[PD] pd~ to sync audio/video
hi list, i am trying out if the pd~ object is an alternative for sync playback of audio and video to the “traditional” method of using two instances of pd talking to each other by netserver/netclient. so the situation is that we need one pd instance with audio on and one without for gem. because audio needs to run without dropouts in the first process, while gem will run in the second process. to run the video in the parent process and the audio in the subprocess with pd~ doesn't work, because the main process needs audio on. (see pd~ helppatch the last lines) to run the audio in the parent process and the video in the subprocess using pd~ -noutsig 0 -ninsig 0 doesn't work because pd freezes when using these parameters on pd~ when using pd~-noutsig 0 it does work, but only if the subprocess will switch its dsp computing on for a moment it can be switched of afterwards. is it a good idea at all to use pd~ for that purpose or should i stick to the netserver/netclient solution? m.

Re: [PD] flext on os X
Hi, oups. sorry I missed it... As I said everything is OK on os X for building flex, and I also can build a copied/modified version of the simple1 tutorial (called simplo1 with a 'o') to test my installation., and everything is ok. I did the same thing on linux ubuntu hardy , and I also been able to build flex, and the same copy of simple1, but when using it I get this bug : - if I open the help file for simple1 , or even one that I edited in text mode to change simple1 to simplo1 , bot of them are working. - BUT if I try to create one of them from scratch, by just doing: File > new, Put>object and typing the name , then Pd is out of order and I just can quit it. (Pd-extended 0.40.3) the ubuntu is running on a AMD 64 bit, running a 32 bit ubuntu hardy (and except this bug everything seems ok) I remember that for the optimisation flag in the config file when I installed flex, I didn't changed the 'pentium4' suggested because most of the other things that installed where also described as 'this is for intel' but where working. could it be this? should I re-install flext again by let it blank ? or put something instead of 'pentium4' ? and what? loic On Mar 4, 2009, at 9:01 PM, Thomas Grill wrote: > Hi Loic, > please direct all flext-related mails to the mailing list. > > > Am 04.03.2009 um 19:53 schrieb Loic Kessous: > >> >> I suppose if I was connected as root this would have not be a >> problem but I wonder if it would not be a problem then to run >> it...I don't know... >> >> anyway, this may help others to add the precision somewhere >> build.txt or somewher else. >> > > did you check out flext from the svn (which is the latest version)? > It's all in build.txt, just below the install commands. > > gr~~~ > ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list

It seems that we should have a string.h for tables then. That would be a good starting point, just make a library that is just Pd interpretations of all the string.h strcpy, etc. functions, but have them operate on arrays and maybe lists of floats too.

Tables also use half as much memory as lists because they are mainly an array of floats, while a list of floats is actually an array of atoms, each atom comprising a tag indicating that it contains a float as well as the float itself. For the network objects the lists are made of floats so the type restriction is not important. Also a table can be reused and resized and its contents never get added to the symbol list so there's no constantly increasing memory involved.

[PD] list issue
hello, ive got some trouble with list handling, maybe somone can give me a hand. i like to group an unnown number of floats in a list. (these floats are the result of different divisors, used all for a fixed value. like 100/16, 100/32...) what i want to do is to put them randomly into the list as long as the sum of all items in the list equals the size of the fixed value. this seems to be pretty difficult...since i use random i cant know what the next float will be. how to handle that? any experience with that issue ? thanks, johannes ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list
Re: [PD] evaluate 3d iterative structures
hello, thanks for the reply, are you telling me to take off all the positions of all the geos and then evaluate in other program? what about gem_listinfo? i could take of all the positions an save them in a text file? and which other software should i use to make this calculations? I just checked there is a Ode version that run in pd , called pyode, i think ode works fine for rigid body simulations, do you think this is a good option in pd?
