Re: [PD] some observations and questions on Pd-ext 0.43.1 beta

(sorry to quote but this will keep the conversation on the list..) Thanks Ivica, it makes sense to try this out. I should have thought about it yesterday. The student and her machine are gone now, but I'll write her and ask to try this out. I still wish to know if anybody is experiencing something similar to better understand the issue. Can't try on my machine 'cause I've got 10.04 and don't wanna change it or alter it by now. Will keep you updated, best, Marco On Fri, Mar 9, 2012 at 12:34 PM, Ivica Ico Bukvic <ico(a)vt.edu> wrote: > ** Just as an experiment, could you please try pd-l2ork to see if you are > experiencing the same problems?

nonlocal message passing scope
by Jonathan Wilkes 09 Mar '12

09 Mar '12

Hello, I was thinking about scope for receive/send names yesterday and thought of a way to implement something more flexible than (explicitly) using $0 to define the scope of send/receive pairs (and possibly other objects that register a symbol). My hack makes use of my "get" method for canvases patch: http://sourceforge.net/tracker/?func=detail&aid=3308027&group_id=55736&atid… Right now I'm seeing several categories, and I'm not sure how they all relate-- meaning they may or may not require different approaches: 1) _this_ canvas, basically what you would get if you prefixed the .x12345 name before the s/r symbol 2) ways to break out of a canvas environment to the parent, parent of parent, etc., all the way to toplevel 3) ways to communicate among abstraction instances, including _this_ abstraction, all abstractions on the parent, parent of parent, etc., to toplevel 4) ways to communicate among all libdir abstractions* 5) global s/r names, abstraction global s/r names #1 is pretty simple-- just add an attribute for the canvas symbol to the "get" method, and prefix it to the s/r symbol. #2 is pretty simple, too-- just use integers to specify how far up the tree you want to go, get the $0 for that canvas environment, and prefix it to the s/r symbol. #3 is similar to #2, except that you also prefix the directory and filename with the $0 #4 is like #3 except that you leave out the filename #5 global is nothing prefixed, abstraction global is the directory and filename with no $0 I've made some abstractions [to] and [from] that can do the job for #1, 2, and global. ($1 for level, $2 for the s/r symbol-- though I'm not sure if that's the best order) The question is do I also try to add the functionality for #3, 4, and abstraction global in those same objects, or do I make a [toabs]/[fromabs] pair for that purpose? In a way it'd be nice if there were a standard way to address all the possibilities above using only argument-- that way it'd be easy to add this functionality to already existing objects, like the array dialog and iemguis, with a single combobox (and simply default to whatever corresponds to global). The problem is that in both #2 and #3 a single float arg would be nice to specify the level so I'm not sure how to differentiate between the two. Also, are there any other contexts I haven't addressed in 1-5? -Jonathan * the only current example of this I can think of is inside the pddp libdir, where there's a global [v GLOBAL_PDDP_DSP] for the dsp status, but I'm not sure if it's used by anything other than ezoutput~.pd.

Making Musical Apps: a book about libpd
by Shawn Wallace 09 Mar '12

Hi all: Peter Kirn over at createdigitalmusic.com has a great review, interview and excerpt of the new O'Reilly book "Making Musical Apps" by Peter Brinkmann: http://createdigitalmusic.com/2012/03/pd-everywhere-free-libpd-gets-a-new-s… I've always thought that Pure Data on mobile devices (with the touchscreen and all the sensors) was a killer app. --Shawn ------------------- Shawn Wallace O'Reilly Media (401) 835-7550 cell swallace(a)oreilly.com www.fluxly.com follow @fluxly

Fwd: Making Musical Apps: a book about libpd
by Julian Brooks 09 Mar '12

09 Mar '12

Hmm - well I did apologise to begin with. There aren't any concerts on this list with paying admission in general, or tbh that many workshops either, though I would admit that there are some as part of conferences etc, which do cost money. As a pseudo-academic I do those a bit but pretty much always taking part in some form. It's the arselicking I'm struggling with "hey guys we're all in this together" (going to shut up and leave this thread alone now). But yeah, genuinely sorry if I caused any offense.

Re: [PD] Editing CSS style, make pd.info better? [WAS: puredata.info site design provocation]

Also thought the same about the bottom icon bar, but it could be good if IOhannes could tell what we can use to replace those icons. I'm afraid without the dotted background, the whole page would feel like floating, and content areas will be difficult to recognize. Screen statistic would be good, actually, can we publicly see the statistics of the portal?

[OT] Fabric Engine
by Ilya Dmitrichenko 08 Mar '12

08 Mar '12

Hi Guys, I have just discovered Fabric Engine a couple of days ago and had been reading on since then, it turns out to be taking pretty amazing approach to hyterogenous computing problem (i.e. simplifying multicore cpu+gpu programming) in a high-level fashion. Please watch this video for some detailed explanation _first_: http://www.youtube.com/watch?v=WWjJE-6Ln24 Well, you currently have to got through quick sign-up procedure to get access details for Node.js or Python module, however I had been told by the guys that they are switching to AGPL license upon product launch next week! So don't get bullshit on me for pointing at a closed-source technology. The main site (fabric-engine.com) has browser-based demos and some details (the docs aren't currently public yet, but can be found here: http://documentation.testing.fabric-engine.com/latest/). > What does this have to do with PD? I'm glad you asked! Basically FE appears to be internally dataflow paradigm which basically uses LLVM to split out and compile multithreaded code for CPU and GPU (using OpenCL) from it's own Kernel Language (KL) which is strongly typed kind-of-JavaScript. Have a look for yourself, but it seems to me that there is definitely a number of people on this list who would pick up on this! Cheers, -- Ilya

Editing CSS style, make pd.info better? [WAS: puredata.info site design provocation]
by Marco Donnarumma 08 Mar '12

08 Mar '12

Hey folks, I got my head around the CSS editing of PLONE. I can do the CSS job, the only downside is that it has to be done with Plone in development mode. This apparently would slow down the site a bit. However, fact is, if we modify a css class, this will affect the whole website. How should we handle this? Voting for the best style, collecting ideas, or.... I can join Chris and send over some styles I've been trying. It would be great to give a better look, at least to the extent that the css allows.

puredata.info site design provocation
by Chris McCormick 08 Mar '12

08 Mar '12

I used FireBug on the puredata.info site to: * Remove three div elements from the page (news, web ring, recent changes, tabbed menu). * Change the CSS stylesheet settings (including the font to 'Ubuntu'). * Remove the 'height' attribute from the images. Other than that it is basically the same site. Cheers, Chris. -- http://mccormick.cx/

six sound outputs with sound blaster X-Fi Surround 5.1
by altern 08 Mar '12

08 Mar '12

hi I am trying to get this sound blaster X-Fi Surround 5.1 sound card to work on windows with 6 outputs http://www.google.com/search?q=Creative+Soundblaster+X-Fi+Surround+5.1&hl=e… The idea is to get a adc~ 1 2 3 4 5 6 and route different sounds to each of the outputs that connects to self powered mono speakers. But I am going nuts. The card only works with 2 outputs under ASIO. And with the default configuration if I set 6 outputs it does some kind of 5.1 mixing. I have tried to disable all 5.1 stuff under control panel but no way... anyone? thanks enrike

[PD-announce] collaboration Belgium
by Joe Higham 07 Mar '12

07 Mar '12

Hi everyone (or nearly everyone), I'm looking for someone to collaborate with on a project for April (2012 of course), here in Belgium. I suddenly got the idea that there might be some Belgian Pure Data sound manipulators out there on the list! If you read this and your interested, get back in contact as soon as possible. Big thanks everyone, and sorry to use this for this type of thing but it seemed a good place to look/ask. Thanks. Joe (Higham). _______________________________________________ Pd-announce mailing list Pd-announce(a)iem.at http://lists.puredata.info/listinfo/pd-announce
