Hi. Thanks for your reply. Yes. In fact that blog post is the perfect example, as it shows a screenshot of how all the other apps that use the camera input (Processing, Max...) behave: I get a request from the system asking me if the application has my permission to use the camera. In launching Pd or using Gem patches, this never happens. And it's just never available. This is why my colleague thinks camera input with Pd broke because of a Mac OS security change that isn't being handled properly. Again, is _anyone_ able to get live camera input to work with Pd/Gem on Mac OSX >10.13? Thanks again! -Dana On 5/19/19 10:42 AM, Simon Iten wrote: > hi, > > i guess you tried setting the permissions manually? > > https://www.idownloadblog.com/2018/08/16/howto-mac-camera-microphone-permis… > > (just the first link that pops up) > > On Sat, May 18, 2019, 16:39 Dana Moser <rosalux(a)curiousart.org > <mailto:rosalux@curiousart.org>> wrote: > > Greetings. > I teach in a program that uses both Linux and > Mac laptops.

Tips and hints for getting a book deal on Pd.
by Alexandre Torres Porres 18 May '19

18 May '19

Hi folks, I think it's time now that I sit and start getting my Pd book project out there. Maybe some of you have seen my live electronics tutorial that I'm working on. It's still in a beta phase and relies heavily on my development in the ELSE library, which is also im active development and still in an experimental beta phase. I have hopes to put out a stable final release of ELSE sometime this year. When this happens, the tutorial will also have a final and stable release but along with it I have plans to also publish a book, where the examples from the tutorial are part of the book. The biggest obstacle and priority now is getting a final release of ELSE ready... Anyway, I never published a book before and I'm a bit clueless on how it goes. I also have zero contacts with any publisher or editor. I wonder if anyone here would have hints on how to proceed, what kind of deal should I go for, how to approach, etc... I would like this publication to have academic value, and that people could get the book on amazon and stuff. thanks Alex

GEM camera input unavailable?
by Dana Moser 18 May '19

18 May '19

Greetings. I teach in a program that uses both Linux and Mac laptops. About a year ago video input stopped working ('High Sierra' version or before, apparently.) I'm told it's no longer working on Windows either. My colleague has suggested it's because enhanced security in the OS is guarded about which devices can access a given piece of software and Pd/GEM isn't asking for permission correctly, so a camera never shows up as an input device. Is this possible? We're using Pd 0.49.4 and Gem 0.93.3. Is there a known method of getting a live video camera input for the Mac? It works fine on Linux. Thank you for any assistance. -Dana Moser

Pd Gem versions summary
by Peter P. 18 May '19

18 May '19

Just a quick question about Gem installable via Deken on OS X. The "Find externals" search on a 10.6.8 os lists Gem/0.94 with the comment "deken-archive for old OSX>10.6 PowerPC/Intel32bit/Intel64bit Shouldn't that be "...old OSX<10.6...." ? To what extend does deken filter search results according to individual os and/or cpu version or architecture? Then http://puredata.info/downloads/gem/releases/0.94 indicates the presence of an os x binary of Gem 0.94deken-archive for macOS Intel/64bit (macOS10.12+) I am obviously confused with the difference in 32/64bit CPUs 32/64bit OS 32/64bit of Pd binaries and their relation to 32/64bit external pd libraries. And wonder which version of Pd AND Gem to install on all versions of OS X upwards from 10.6. There does not seem to be single location with this information, I checked http://puredata.info/downloads/gem/releases/0.94 http://msp.ucsd.edu/software.html http://gem.iem.at/ but perhaps I am missing something. I would like to compile this information in order to say that On all(?) versions of Windows on a 64bit CPU I install the 64bit binary of Pd pd-0.49-0 On all(?) versions of Windows on a 32bit CPU I install the 32bit binary of Pd pd-0.49-0-i386 Or does it matter if the Windows itself was compiled with 32 or 64 bit? On OS X 10.6 or later I install the 64bit binary of Pd pd-0.49-1 On all(?) OS X versions on 32bit CPUs I install the 32bit pd-0.49-1-i386 but I can/have to install this on 64bit CPUs as well if I want to load 32bit externals, right? Now if the above is true, which Gem version and architecture would correspond to the above cases? Thank you for all insights! P

Strange behavior of savestate
by Philipp Schmalfuß 17 May '19

17 May '19

Whenever an abstraction containing savestate is copypasted/duplicated, it'll recall the state of the original. to check this, just duplicate one of the abstractions in savestate-help.pd. One would expect it to initiate with the default parameters (0). instead savestate recalls the parameters from the original abstraction and it sends a bang out of its right outlet. This should only happen when the parent patch is saved, right?

GPIO pi-extras
by Max 16 May '19

16 May '19

In this message from 2015 I read about a GPIO external by Miller in something that's called "pi-externs". Where can I find that? https://lists.puredata.info/pipermail/pd-list/2015-08/111237.html thanks.

Re: [PD] Delay (msec) option in audio properties

Is this in the Pd Manual somewhere?

Comport problem with Arduino: 13 is coming in as 10
by Ingo 14 May '19

14 May '19

Hi there! I'm getting number 10 instead of 13 from my adruino. I remember something that 13 is something like "end of line" or "carriage return". In some cases 13 was replaced by 10 for some sort of simplification - I don't remember any more details. What can I do to set up [comport] to output the correct numer 13 instead of 10? There should be a setting for not treating it as a "modem" ... Thanks! Ingo
