tanh~ (core dumped)
by Kosmas Giannoutakis 01 Sep '17

01 Sep '17

Hi, i want to implement the tanh function in PD Vanilla. I use the formula y(x) = (1 - b*e^-(a*x + lnb))/(1/b + e^-(a*x + lnb)) where (a) is a steepness parameter and b controls the amplitude range. You can see my implementation which seems to work, but when I incorporate it to larger patches, I get a core dumped... Any clue why is this happening or any suggestions for a better implementation? Thanks, Kosmas

[PD-announce] Debian/stretch: Pd-0.48
by IOhannes m zmölnig 31 Aug '17

31 Aug '17

this is just to announce, that the latest and greatest Pd is now also available pre-packaged for Debian 9 ("stretch"). Debian/stretch has been released in June 2017, *before* Pd-0.48 was released. Debian policy does not allow updating packages after a Debian release, which often means that users end up with out-of-date packages (after all, Debian does a release every 2 years or so; which means that available packages can be several years old - esp. if people insist on not upgrading to the latest Debian/stable). in comes Debian/backports, which allows users to install up-to-date packages on their stable Debian systems, with full Debian support. For instructions on how to enable this, see: http://backports.debian.org/ I intend to provide backports for all Pd related packages (Pd-vanilla and all those externals available). I do not intend to provide backports for Debian/jessie (RaspberryPi users are advised to upgrade to Debian/stretch; really anybody is advised to do that) mfgsdr IOhannes sidenote: i generally recommend to use Debian/stable on servers, and use Debian/testing (constantly updating) for anything multimedia related (as you usually don't want to use multimedia applications that are several years old). with Debian/backports you can have the best of two worlds - a rock solid OS with some select up-to-date applications. _______________________________________________ Pd-announce mailing list Pd-announce(a)lists.iem.at https://lists.puredata.info/listinfo/pd-announce

hexloader incorporated into vanilla?
by Alexandre Torres Porres 31 Aug '17

31 Aug '17

Howdy, don't think this has ever been discussed... sorry if it had. So, we need externals with non-alphanumeric names to be loaded into a multi-object library, loaded via start up. If you have them as a set of single-object binaries, the only option seems to be [hexloader] (a third party external). Hence, in order to reduce dependency on third party externals, would there be any opposition in the idea of incorporating the hexloader code into Pd Vanilla? An alternative could be 'deken' handling dependencies, so if you download one external pack it would also download a dependency such as 'hexloader'. thoughts? cheers

[text] - notify outlet
by oliver 31 Aug '17

31 Aug '17

hi, just discovered the new [text] feature - the "notify outlet" atm it only sends the message "updated" when text has been changed in the texteditor (it does nothing when text has been changed with a "set" message). anyway, since it says "... might be extended to offer more information in the future" - it would be great to also send a message when a file has been successfully read ! or a failure message in the other case. BTW: i don't know if the list is the right place for feature requests, would it be the GITHUB site instead ? i didn't manage to open a pull request there despite being logged in. thanks for any hint in this regard ! best oliver -- \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\ /////////////// http://pendler.klingt.org ////////////// \\\\\\\\\\\\\\\ http://oliver.klingt.org \\\\\\\\\\\\\\ ////////////////////////////////////////////////////////

[Gem] seamless texture mapping
by Roman Haefeli 30 Aug '17

30 Aug '17

Hey all I am mapping an image as texture onto a cylinder. The image is mostly white and at the joint where both ends meet a thin black line is visible. Is there a way to disguise the joint so that the texture appears seamless? Thanks, Roman

Five Days of Pure Data
by Antonio Roberts 30 Aug '17

30 Aug '17

Hey pd list, This week I've been publishing a series of writeups on my blog of patches and techniques I've been using in Pure Data over the years. So far I've written about: Converting images to signals - http://www.hellocatfood.com/five-days-of-pure-data-image-to-signal/ Randomising text - http://www.hellocatfood.com/five-days-of-pure-data-randomise-text/ Infinite scrolling using [repeat] - http://www.hellocatfood.com/five-days-of-pure-data-infinite-scrolling/ Two more will be published this week about livecoding and stop-motion animation. I hope that some people find it useful! Antonio -- ============================ antonio(a)hellocatfood.com http://www.hellocatfood.com ============================

purr data duplicate undo
by school shoes 30 Aug '17

30 Aug '17

<mailto:pd-list@lists.iem.at> Hey - every now and then using purr data i find that i have inadvertently made duplicate objects/msgs etc that are directly in front of each other. I've finally figured out that this is happening with the following sequence: cmd +d , cmd+z in pd vanilla the same combination simply undoes the duplicate command, which is probably the expected behavior. But in purr data it doesn't delete the duplicate, but moves it directly in front of the original. Not sure if this is a bug, but thought i’d bring it up as a couple of times has led to some time consuming trouble shooting, because duplicate objects sitting directly on top of the original can look like they are connected to things when they are not. using purr data 2.3.0 on macos sierra cheers, ss

Tcl error with "tof" breakpoints in MAC
by José Rafael Subía Valdez 29 Aug '17

29 Aug '17

Dear list, I have been trying out the latest version 0.48 and some old externals. Unfortunately, the [breakpoints] GRAPHICAL object from the "tof" library spits out this tcl problem: (Tcl) INVALID COMMAND NAME: invalid command name ".x5808180.c" while executing ".x5808180.c create rectangle 85 355 281 466 -tags 66d980S -fill grey86 -width 1" ("uplevel" body line 150) invoked from within "uplevel #0 $docmds" this makes Pd unresponsive when I try to close that window too. the object works fine in Ubuntu 16.04 I do not know if this is a library issue or a Pd thing. the library has not been updated for a while now, but it is very useful. Does any one know what seems to be the problem with the object? tested on mac yosemite 10.10.5 -- José Rafael Subía Valdez www.jrsv.net
