xapian search engine for Pd
by Hans-Christoph Steiner 18 May '09

18 May '09

Hey, I've been thinking for a while that Pd really needs a good built-in search function. I just found this Xapian search library that has good Tcl bindings, anyone ever used it? I suppose it could also be implemented in C in 'pd' rather than in Tcl in 'pd-gui'. It seems like a pd-gui thing tho. .hc ---------------------------------------------------------------------------- As we enjoy great advantages from inventions of others, we should be glad of an opportunity to serve others by any invention of ours; and this we should do freely and generously. - Benjamin Franklin

Pd-extended 0.41.4-rc2 released
by Hans-Christoph Steiner 18 May '09

18 May '09

http://at.or.at/hans/pd/installers.html It's looking quite stable, so please try it if you haven't already so we can find the last bugs. As far as I know, there aren't any outstanding bugs that need to be fixed for this release besides the Tcl/Tk 8.5 issue on GNU/Linux. Test away and file bugs in the bug tracker! http://puredata.org/dev/bugtracker This release candidate includes: * Windows build * moocow/readdir included on Windows * Debian lenny/stable PowerPC build * added/fixed "Next Window" menu item and key binding (Cmd-` on Mac OS X) KNOWN BUGS Check http://puredata.info/dev/bugtracker before reporting bugs, and if you find an existing bug report on the same issue, please add your information there. - the fonts are messed up when using Tcl/Tk 8.5 on GNU/Linux - Escape, Enter, and Ctrl/Cmd-W don't close the Path and Startup preferences - pdp_opengl is alpha and will definitely crash Pd - loading pdp_opengl will crash Pd if X11 is not open before trying to load it ---------------------------------------------------------------------------- Looking at things from a more basic level, you can come up with a more direct solution... It may sound small in theory, but it in practice, it can change entire economies. - Amy Smith

basic resonant filters in Pd
by brandon zeeb 18 May '09

18 May '09

Hallo, How does everyone implement basic resonant filters, ie: LPF, HPF, BPF, in Puredata? [lop~], [hip~], and [bp~] are nice, and can easily be strung serially to create 2nd, 3rd, and 4th order filters, but lack q. [biquad~] seems up to the task, but I'm unable to find any information in the help file or docs online pertaining to how one could replicate standard filters using this object. Cheers, ~Brandon

feature request: arrays with colors
by João Pais 18 May '09

18 May '09

Probably this was asked already: how about setting a variable for a color of the line of an array? That would make data comparison quite easy (when several arrays are on the same graph). Of course it might be possible to do this with data structures or with gem, but it would be much easier to perform it with only one variable. I'm not a programmer, but this doesn't seem to be a complex thing to do, basically opening up a variable which was so far closed. best, JoÃ£o Pais -- Friedenstr. 58 10249 Berlin (Deutschland) Tel +49 30 42020091 | Mob +49 162 6843570 jmmmpais(a)googlemail.com | skype: jmmmpjmmmp

GIT repo
by Timur Batyrshin 18 May '09

18 May '09

Hi all! I am going to build and maintain RPM of puredata for ALT Linux. It uses git for building RPM packages so I want to pull from existing RCS (git preferrably) repositories of pd-vanilla and pd-extended if any. So my question is: Is there a working git repository of pd-vanilla and/or pd-extended or is the development held in SVN or such? Found only tarball of git repository on Miller Puckette's page (which obviously not exactly what I need) but no other links to git repositories. Thanks for any advice in advance.

using 2 web cams with GEM for multiblob
by punchik punchik 17 May '09

17 May '09

Hello, im working on a interactive installation, im using a web cam in the roof to track the movements of people in a space. The thing is that the roof is not so tall, so i just can track a little space. So i was wondering if a i oould use 2 web cams in gem and render both videos as textures in one square in gem. I need to join both videos from the web cams into one for using the pix_multiblob object to tracking multiple blobs. Is this possible? Do anybody have tried this before? thanks Sebastian

Hello, what would be the most adequate design approach for a filter described in the score of Luigi Nono's "Omaggio a György Kurtag" concerning the loss of energy with an edge steepness of that kind (s. attachment)? Thanks for your help, Achim
