[PD-announce] jit_expr 0.1: Just in time compiled expr/expr~/fexpr~
by Alex 19 Mar '18

19 Mar '18

jit_expr is a clone of the pure data expr/expr~/fexpr~ objects. It just-in-time compiles its expressions so they should be much more optimized than the original. If all works as designed, they should use less CPU than the equivalent vanilla, non-expr, patching and have a significant CPU advantage over the original expr objects. I've put the external, compiled for 64-bit Mac-OS and 64-bit Linux, up on deken: in pd, go to help menu, find externals, search for "jit_expr". After installing the external you should be able to change any of your expr family of objects to just in time compile by loading the library, [declare -lib jit_expr], and then prefixing the object name with "jit/", for example [jit/fexpr~ $x1[0] + $y1[-1]]. I believe they are feature complete with the originals but I'd love to know if there is anything that I'm missing or any bugs that you discover. I'm not exactly sure how to profile pure data patches. If anyone has a good approach or original expr~/fexpr~ patches that use a lot of CPU you can share, let me know. Compiling in the object takes a little bit of time, so the initial instantiation of the object/expression will be a bit slower than the original, FYI. Please report any issues here: https://github.com/x37v/jit-expr/issues BTW, if you're curious to see the llvm assembly produced by your expression, send the |print( message into the left most inlet of your object then check out the pd console. I would love help building Windows and 32-bit Linux versions of the externals. I'm guessing we could also do raspi/arm builds but we'd need some changes to the source code as it uses llvm and explicitly generates code for x86 right now. The source code can be found in the git repo: https://github.com/x37v/jit-expr -Alex Norman _______________________________________________ Pd-announce mailing list Pd-announce(a)lists.iem.at https://lists.puredata.info/listinfo/pd-announce

Makefilename crasher
by Chris McCormick 19 Mar '18

Hi, I found a buffer overflow via makefilename which segfaults Pd. Have attached a patch which replicates this behaviour. Let me know if more info is needed. Cheers, Chris. -- http://mccormick.cx/

web broadcast latency
by info＠hansroels.be 19 Mar '18

19 Mar '18

Hello, I want to broadcast a live audio stream from a performance in a library: two musicians are playing on controllers + Pd patch. There is no acoustic sound, people visiting the library can just watch the silent performance. If these visitors want to listen, they can go to a website and listen through the media player on their smart phone or laptop. I want the latency to be less than 1 second (or better: less than 500ms) to ensure that the audience can experience a relation between the sound (from the webstream) and the visual performance. Does anyone have experience with this kind of setup and is it possible to have such a low latency through a web broadcast? (or do I have to look for another solution, perhaps FM sender?) In older posts of this mailing list people were talking about latencies from 1 to 10 seconds. Which external shall I use to send the sound in Pd to Icecast? I guess oggcast~ or mp3cast~ , or is there a better solution (= lower latencies) outside Pd? best, Hans Roels --

Browser UIs for vanilla Pd patches
by Chris McCormick 19 Mar '18

19 Mar '18

Hi, Building on the excellent work of Nicolas Lhommet[1] this is a small system for making browser based user interfaces with which to control your Pd patches: https://github.com/chr15m/pd-ws/ Here's an animated GIF of a user interface built with NexusUI.js[2] controlling a Pd patch: https://raw.githubusercontent.com/chr15m/pd-ws/master/screencast.gif I would be good to fold this functionality into PdDroidParty / PdParty such that if an index.html exists in a droidparty project folder then that will be used as the primary interface in place of the gui-patch-faking that goes on at the moment. This will allow for much richer user interfaces for Pd patches on mobile devices. Interested to hear what you think of that, Dan. Thanks to Nicolas for kindly allowing me to re-license this collaborative work under the GPLv3. Cheers, Chris.

[PD-announce] jit_expr 0.1: Just in time compiled, expr/expr~/fexpr~
by mario buoninfante 18 Mar '18

18 Mar '18

yap, it looks there are some issue loading the objects. if you go to Browser list and then launch jit_expr help, then you'd be able to load the object. I also tried creating [jit_expr/jit_expr] that returns an error: jit/expr,expr~,fexpr~ version 0.1 maximum object loading depth 1000 reached but after that I'm able to load the object. I'm using Pd 0.48.0 on Linux 64bit cheers, Mario

[clone] observations
by Max 18 Mar '18

18 Mar '18

Hi list, Miller. A little late to the game I started to use [clone]. Some observations: 1. If the abstraction name already exists as an external, it fails to instantiate. Meaning you can't do [clone spigot 10] or [clone disk 4]. I think this is a bug, as the local abstraction should override any built in objects or externals. 2. In the helpfile the example is [clone clone-subpatch 16] which is confusing, I think it should be [clone clone-abstraction 16] because that's what it is in Pd terminology, right? (A subpatch being [pd subpatch]) 3. When saving a cloned abstraction that has ben opened through the clone object it closes itself. That probably has a technical reason but for the user experience it is a little annoying. But generally I really like the functionality of it. Greatly simplifies some of my patches. I hope my feedback was helpful. m.

Hi, this is ground breaking, absolutely amazing. correct me if I'm wrong, but that means with this tool we now have something like gen~ in Max (btw, I know there's Faust that works with Pd). anyway, super cool, I'll give it a try asap. cheers, Mario
