Re: [PD] Blur FX on a specific area on video and camera focus blur
by Samuel Burt 30 Jun '10

On a related note, I've been hoping to find a way to add movable camera focus blur to 3-d primitives. Is there an easy way to do this with Gem?

[OT] linux preempt kernel vs rt kernel
by András Murányi 30 Jun '10

30 Jun '10

Hello people, does anyone know what is the real difference between an 'rt' and a 'preempt' kernel in linux? I noticed that the newest rt is not always available any more for my arch, whilst this preempt thing has appeared in the repo... Is pdextended -rt supposed to like my preempt kernel? Thanks, Andras

Why not clear printout?
by Matteo Sisti Sette 30 Jun '10

30 Jun '10

Hi, I've just noticed Pd-Extended 0.42.5 doesn't have the useful "clear printout" button that Vanilla (0.42.5) has. I know it is a relatively recent addition in Vanilla, but I'm comparing the same version number. Has it been intentionally removed in Extended?

Blur FX on a specific area on video.
by Olivier Baudu 30 Jun '10

30 Jun '10

Hi, We want to process a blur effect on a specific area on video. To be clearer, we want to blur faces... To find faces, we use [pix_opencv_haarcascade ]... How can we do to blur this area, and only this one ? Thanks 01ivier

problem with arduino digital ins - Pduino-0.5beta8 / Firmata 2.1
by Ingo Scherzinger 30 Jun '10

30 Jun '10

Hi, I'm having a problem with the arduino digital ins. According to the arduino website there are pull up resistors inside the ATmega that get activated automatically when the digital ins are turned on. This is not the case here with the Pduino-0.5beta8. When I connect ground to the pin it switches to 0 as expected. When I disconnect the wire it starts switching randomly between 0 and 1. If I use an "external" pullup resistor everything works as expected again. I just read the help file from the pduino and it states that this is the normal behaviour which shouldn't be the case with the internal pullup resistors activated. What's the problem with these internal pullup resistor not getting turned on? Is there a command I can (or have to) send to the arduino? I've tested this with a diecimila and duemilanove and Ubuntu 10.4 and Windows XP. Maybe there is a problem with Pduino or Firmata 2.1? Any ideas appreciated! Cheers, Ingo

What's up with the mailing list archives and/or Google????
by Matteo Sisti Sette 30 Jun '10

30 Jun '10

Hi, I often search the archives using "foo bar site:lists.puredata.info" in Google (since the search engine of the archive is pretty useless). Usually it works fine. However, today I tried a few searches, and 100% of the times, when I click on a search result returned by Google, it takes me to a totally unrelated message. For example if you search for "berlin site:lists.puredata.info", the first search result is "[PD] [PD-announce] Blank Pages Berlin - search for a place" but if you click on it, it takes you to: "[PD] Re : Split multichannel audio file into stereo pairs" Any idea what may be going on?? Is there any other mirror hosting the archives so that I could try searching there instead of lists.puredata.info? Thanks m.

Re: [PD] send midi to another program in windows? (not with [midifile])

There is no noticeable latency with midi yoke on any of my systems here. Ingo > Date: Wed, 30 Jun 2010 12:07:48 +0000 > From: Andr?

Hi Joao, You can use LoopBe1 or MIDIYoke. They're both free. Regards, David Kirkpatrick Sound and Multimedia Artist www.davidk.com.au --Forwarded Message Attachment-- From: jmmmpais(a)googlemail.com To: pd-list(a)iem.at Date: Wed, 30 Jun 2010 12:19:10 +0200 Subject: [PD] send midi to another program in windows? (not with [midifile]) Hi, my attempts to work with [midifile] didn't work, as something in the files is saved wrong, and all my midi-related programs (sibelius, reason, logic,...) display a much slower file than the one I saved. Also, midifile only takes integers as midipitches, which is rather limiting. I wanted to send midi directly from Pd to any of the other said programs. Can anyone recommend a jack-kind of software for midi?
