@Rojo, you can't abort manually using CTRL+., the menu get disabled. I'll improve to show a Run To Selection case too.

@Murta I mean the same way I always abort from a dialog

Running ExitDialog@Unevaluated@Abort[]

@Rojo Cool... this works. I Didn't know about ExitDialog@Unevaluated@Abort[]. There is some keyboard to simulate it?

(Perhaps you need an extra Unevaluated from a button? Not sure)

@Rojo I created a shortcut in my standard pack for ExitDialog@Unevaluated@Abort[] works nice. Tks

No problem

I complemented the post with your code. See here

Can I make a command that erase itself after execute?

myAbort[]:=(ExitDialog@Unevaluated@Abort[];ClearMe...)

So the line disapears?

@Murta Nice

Sure

I will end up crazy because of MMA one day

Hi does anyone know, will the Wolfram Language be a package of all the features and functionality listed at this site reference.wolfram.com/language , bundled together? Or will you have to pay for each sub program separately?

Hello,

I've looked at the documentation, but it's quite confusing for a novice like myself. Is there some kind of beginner-friendly guide to exporting Mathematica functions to C, or other executable programs?

Thank you

@MatsGranvik hmmm... at first glance most of the stuff should be included in Mathematica. But I may well be wrong and not up to date on the new marketing strategies of WRI.

@Aron no luck with the documentation?

@MatsGranvik This is the documentation for Mathematica although it is now called Woflarm Language and I'm sure everything will as usual be included in Mathematica.

Is this useful: mathematica.stackexchange.com/q/10920/131

@halirutan Woflarm? ROFL!

@YvesKlett :-)

Hey peple

I'd like to be able to create sound real time from MMA. Do you konw a straightforward way?

Say a slider that changed the pitch of a continuous sound

Some java/.net class where you can buffer the data to be played?

@YvesKlett should call it Wolflärm

describes the PR stuff very well

@SjoerdC.deVries :D

Viel Lärm um nichts - or perhaps more fitting - alter Wein in neuen Schläuchen. But such is company life.

That notwithstanding, I have the greatest respect for the developer teams. A lot of brilliant people there.

(Plus, they know how to party. Well some of ´em, at least)

@YvesKlett You've been there more often than I (I went only once), so you should know.

@Rojo Alas...

@Rojo you need @halirutan.

Hello, and hello

I need you @halirutan

yes you do

@MichaelHale Yeah, thanks. But I'd like something better

even if external

Does anyone know if ViewMatrix will work with AbsoluteOptions in V10 again as opposed to the current broken state?

Geiger counter!

@VitaliyKaurov you know, I am planning a trip to Tokyo, and this makes me think...

@VitaliyKaurov That's cool, but a lot of these seem to just boil down to "Look, Mathematica can add numbers and plot them!". Some of the posts on Wolfram blog (such as Sasha's probability post or your jigsaw puzzles or several of Michael Trott's) are good examples where Mathematica's potential truly comes across. I haven't seen a single RPi/Arduino example on Community that couldn't have been done just as easily in python.

Maybe the problem is me and I should just stop being a cynical asshole :P

@rm-rf low blood sugar?

@rm-rf assuming you already know Python :P

Hi, I have a quick question: How do we check if a 3D graphics is empty or not? Do we have something like EmptyGraphQ?

@Rojo Well, I guess what I'm trying to say is that Mathematica is truly capable of doing some things effortlessly and better than other systems out there, so just calling a Device* function and then passing it to ListPlot isn't "impressive" when the actual "cool" part of the project is in the $150 equipment.

@rm-rf Agreed. Do you know what devices those functions can recognize, or how to set them up? Have you seen a tutorial around?

@Rojo The ability to browse by measured quantity here is pretty cool: devices.wolfram.com

@Rojo I was just going to point to the page that Michael linked to. That's all I know about what's supported.

Thanks you two. I'm looking into

the curated devices of the internet of things

@rm-rf RPi and other devices project is at the beginning of the journey for now. Exploring myriads of connectivity choices first is like examining IKEA pieces before you assemble a couch ;-)

@Rojo Have to clear this with my wife first..

@halirutan Hehe

@Rojo Do you really want to try real-time sound with Mathematica?

@halirutan Only if it's possible

Is it?

40k samples per second doesn't sound that fast to generate

in MMA

@Rojo I'm really not sure and I wouldn't try. Do you plan to do something real or is it just a play tool like the Geiger-counter?

@halirutan Play tool, possibly useful play tool, but nothing serious

@Rojo The thing is, that sound under Linux with Mathematica is really a pain. So when you are on Windows, there might be things that work. Here, it is very unlikely.

@halirutan Oh ok.

And how would you proceed if you were me?

@Rojo Try NAudio if you want to use .NET: naudio.codeplex.com

I'm about to google if there's any .net or java code around

@MichaelHale Thanks

It would be enough if I just could control frequency, source, some filter, like a basic subtractive synth

Not ideal but enough

@MichaelHale Checking it out :)

Without a library on .NET you need to parse WAVs manually with a BinaryStreamReader or whatever.

And they still call that high-level, compared to Mathematica's Import, heh.

@Rojo Hehe... this here Sound[SampledSoundFunction[Sin[0.125 #] &, 4000, 8000]] crashed my Mathematica and froze my browser :-)

@halirutan Wow, sucks. Works on Windows

Although there is a shortcut SoundPlayer class if you just want to play it but not modify the WAV, and you could maybe use XNA game library for simple pitch adjustments and easy playing.

I guess what I would do is make a RealTimeAudio class that uses NAudio which maintains a stack of sample lists which it plays in order. Then I would expose methods to periodically push new clips onto the stack from Mathematica.

I might not even use NAudio, just put a WAV header onto each sample list it gets from Mathematica and use SoundPlayer.

@MichaelHale Thanks a lot

I'll let you know if I succeed or get stuck

Sure thing

@MichaelHale But you have to create a wav file with SoundPlayer?

No, you can use a MemoryStream to avoid calls to disk.

It can play from any Stream, so FileStream, MemoryStream, NetworkStream, etc.

@MichaelHale Grreat
