Re: [PD] Gridflow+ L2Ork pd-extended (was: L2Ork pd-extended release candidate 1 now available)

Not as comprehensive (no web browser and between instances of PDF beyond what tcl/tk clipboard offers). I wasn't even aware that desiredata did that :-).

Fwd: Reading and writing binary files
by David 27 Feb '11

27 Feb '11

Thanks for the suggestion. I'm not sure I can use this method, though, because I have to be able to write it out as well. According to the help documentation, the '-raw' flag only applies to reading files. Is that correct? Anyway, I tried it and I'm getting a usage error: error: usage: read [flags] filename tablename... flags: -skip <n> -nframes <n> -resize -maxsize <n> ... -raw <headerbytes> <channels> <bytespersamp> <endian (b, l, or n)>. Here's what my patch looks like. I'm not sure what I'm doing wrong. [read -raw 0 1 8 n Default.syx array1( | [soundfiler] There's no "header" in the file, it's just raw data for a Midi sysex message, and I want to read each byte as an integer value in the range of 0 to 255.

URGENT: OpenNight and FLOSS Hackday change - Sunday 27th Feb @ the Others.
by Robert Munro 27 Feb '11

27 Feb '11

There has been a double booking during the day @ the others - the Hackday CANNOT go ahead. I am very sorry, just rang up today to find out when we can get in and it appears there was some misunderstanding (multiple people at the venue involved). The OpenNight will go ahead as planned from 6pm. If you still want to to a presentation, we can do them at the start before the performances. So DONT go to the other at 12pm - go there at 6pm. regards, Rob On Thu, Feb 17, 2011 at 12:56 AM, Robert Munro <ml(a)robmunro.net> wrote: > The next openlab hackday and opennight next Sunday 27th Feb @ the Others ( > http://www.theothers.uk.com). > > This is Android and general open-source multi-media salon where people can > come along and hack, present works or generally cross-pollenate ideas.

[GEM] OS X How to compile against SDK 10.5 in os x 10.6
by Jaime Oliver 26 Feb '11

26 Feb '11

Hi, I started a new thread as I believe people will start getting this problem soon. The previous thread was: gem compiling error I am trying to compile GEM from source in a macbook pro using osx 10.6 and pd-0.42-5, latest Gem (0.92-1) from cvs and xcode 3.21. Chris Clepper suggested to compile against sdk 10.5. sdk 10.5 installed, but can't figure out how to make it the target. some programs have a flag like --with-macos=/.../sdk10.5, but can't find any reference in the ./configure -h other sites suggest to modify the makefile, but no luck yet. I also tried: make --include-dir=/Developer/SDKs/MacOSX10.5.sdk/ can anyone suggest how to do this? best, J -- Jaime E Oliver LR joliverl(a)ucsd.edu www.realidadvisual.org/jaimeoliver www-crca.ucsd.edu/ www.realidadvisual.org 858 202 1522 9168 Regents Rd.

(i don't think you can use pix_artoolkit compiled for Gem-0.93(svn) with Gem-0.92-3) amsdr IOhannes

Pd 0.43-0 test +Gridflow (was Gridflow+ L2Ork pd-extended)
by ALAN BROOKER 25 Feb '11

25 Feb '11

Hi Thanks, yes wanted to see if it was compatible at your end- just to give some brief feedback,-I have actually been using Gridflow + vanilla Pd 0.43-0 (test 3) on Ubuntu and it works mostly. The big issue for me was the help index, which would completely crash PD when selected, but PD 0.43 is a test release I suppose. So for me, other than the help index (and perhaps some examples which crashed PD) it is usable On Wed, Feb 23, 2011 at 5:18 AM, Mathieu Bouchard <matju(a)artengine.ca> wrote: > On Tue, 22 Feb 2011, ALAN BROOKER wrote: > >> tried quickly L2Ork with Gridflow 9.14 and both are working great-big >> thanks :) > > I haven't done any testing nor debugging with L20rk, and AFAIK, I haven't > fixed anything that caused a problem with L20rk.

GEM problem with [alpha] on MacOS
by Matteo Sisti Sette 25 Feb '11

25 Feb '11

Hi, The attached patch works as expected in Linux, but in Mac OS the rectangle with the texture generated by pix_movement is not transparent. It is a black-and-white opaque image. [pix_movement] SEEMS to be working as expected and generating the correct alpha channel (judging from the values I got with a [pix_blob] in mode "4"), so I think it is [alpha] that is not actually enabling alpha. I have Linux and don't have a Mac, and when I observed the issue I couldn't take the time to do the obvious tests (such as trying with a solid color with alpha and no texture at all, and trying pix_image with a png image with alpha channel). Can anybody confirm this? I also tried sending [alpha] a "1" on the left inlet (not necessary in linux), just in case alpha was disabled by default in MacOS but that didn't help. Is there some extra thing I have to do in order to have alpha work in Mac OS? I am using GEM 0.92.3 in Linux and I think the same in Mac (the one bundled in the latest Pd Extended). Thanks in advance m.
