by difusion 31 Jul '09

31 Jul '09

Visualizar'09: Public Data, Data in Public Call for projects and papers *International Workshop-Seminar on Public Data Visualization November 12 - 27, 2009 in Medialab-Prado (Madrid, Spain) Deadline for projects and papers: October 5, 2009* *Call for collaborators: October 16 - November 11, 2009* http://medialab-prado.es/visualizar Directed by José Luis de Vicente. Teachers: Ben Cerveny (Stamen) and Aaron Koblin. With the support of Bestiario. This new edition will focus on the implications of using data structure visualization to aid in public processes of decision-making. Selected projects and papers will tackle the topic of Open Data and Visualization for Government Transparency and Civic Engagement. Visualizar'09 includes an* international seminar *and an *advanced project development workshop*. Both activities will tackle the topic of transparency of data to make public discussion and debate possible, regarding the political, social, and scientific processes. Consequently, one of the objectives of Visualizar'09 will be the development of new strategies for communicating these data and returning them to the public domain. All those interested in collaborating in one of the selected projects can sign in from* October 16 to November 11*. *Submission of databases:* Public databases of institutions or research groups interested in sharing them and making them more available to citizens can be sent to visualizar[arroba]medialab-prado.es or through http://medialab-prado.es/visualizar Submitted databases could serve as work material for data visualization projects selected for this workshop. *More information:* http://medialab-prado.es/article/convocatoria_de_proyectos__visualizar_09_d… visualizar(arroba)medialab-prado.es With the support of the Spanish Foundation for Science and Technology - Ministry of Science and Innovation (FECYT - Ministerio de Ciencia e Innovación) -- Nerea García Garmendia Comunicación / Press Medialab-Prado Área de Las Artes, Ayuntamiento de Madrid Plaza de las Letras Alameda, 15 28014 Madrid Tfno. +34 914 202 754 difusion(a)medialab-prado.es www.medialab-prado.es _______________________________________________ Pd-announce mailing list Pd-announce(a)iem.at http://lists.puredata.info/listinfo/pd-announce

Re: [PD] changeable receive

You probably could approach the problem differently, so using 'selectors' on the messages, and then using [route] to get them where they need to go. .hc Hans Roels wrote: > hello, > > From what I read and tried, it is impossible to change the argument of > 'receive' (like the right inlet of send) in Pd-vanilla. > Is there a trick to solve this in vanilla? > > I want to be able to insert the names of various receives in symbol > boxes.

You could use a bunch of spigots, or [list prepend] + [route], but both have the limitation that you must know what the receive names are ahead of time. Here's a solution that uses dynamic patching. If there's a way to do this in vanilla without it, I'd like to know it, too. -Jonathan

Hallo, Hans Roels hat gesagt: // Hans Roels wrote: > From what I read and tried, it is impossible to change the argument of > 'receive' (like the right inlet of send) in Pd-vanilla. > Is there a trick to solve this in vanilla? I believe, renaming a receive is bad practice in general (I've never used this in many years of Pd patching, not even where I could like in sliders or tables.) So I would rather recommend to rethink the problem you're trying to solve. It's much better to rename at the other end i.e. the [send] or the [tabread] because that's the area "where the action is" anyway and in most cases you get the same net result. If you really want to send something from a single send and distribute it to different receives, you can use something like the settable "route" called [sroute] that is part of the [list]-abs although it doesn't belong there. It's basically wrapping a select with a list to emulate route. Or use something like demux/spigot. Just think of what you would do with direct connections. Ciao -- Frank

changeable receive
by Hans Roels 29 Jul '09

29 Jul '09

hello, From what I read and tried, it is impossible to change the argument of 'receive' (like the right inlet of send) in Pd-vanilla. Is there a trick to solve this in vanilla? I want to be able to insert the names of various receives in symbol boxes. The only way to do this is by using a slider or number box and sending a [receive $1( to this object. This works but 1. I can only receive numbers from this 'receive' and not lists, symbols,... like a normal receive 2. in this way all these GUI are using CPU. Does it help to reduce the CPU consumption if I reduce the size of this GUI to the minimum? I hope somebody has found a hack for this problem? Hans r

If you installed Intrepid or Jaunty from scratch, there is no audio group created by default and the limits.conf additions won't work. Add an audio group and add your user to it. Running pd or jack in realtime should work. I had smooth performance on my old Thinkpad T42 with comparable specs. --- Dan Wilcox danomatika.com robotcowboy.com

Control rate (Was: Sysex out problems)
by András Murányi 29 Jul '09

29 Jul '09

Well i was hoping i wouldn't have to use any kind of timers for that job... [int] followed by [change] do a good and (in terms of cpu) inexpensive job, but to "resample" my control flow i will need [metro] or [pulse] afaik... if i do that, of course i will not add a [metro] to each knob and envelope but i will set up a central "control clock" with a single [metro] and then i will feed this to every part that needs to "resample" control signals. This leads me to the question (i remember it coming up earlier but i cannot find the topic sorry), if i want to basically modify pd's own control rate, is there a more direct/general way to do it?

Problems with DIO errors / audio clicking
by James Dunn 29 Jul '09

29 Jul '09

I'm having problems with DIO errors and glitchy audio with PD-extended 0.41.4 My computer is an HP Compaq nc6000 1.6Ghz laptop with 500mb RAM and I'm running Ubuntu 9.04. The kernel is 2.6.28-13-generic and I've tried using the realtime kernel which is 2.6.28-3-rt but it's no different. I've tried editing /etc/security/limits.conf to include the lines: @audio - rtprio 99 @audio - nice -19 @audio - memlock unlimited but this hasn't helped either. I start jack with qjackctl and my settings are: Realtime, No Memory Lock, Frames/Periods: 1024 sample rate 44100, Periods/Buffer: 2,. Can anyone help? thanks James
