@RolfMertig In my field, many people use R -- not just for stats but as a general scientific programming language. There's a huge ecosystem of user-written packages that extend it's use and it's hard to compete with free.

How to inter into the chat room from the new layout?

Oh, it's normal now. But it don't work before I ask it...

@RolfMertig I think only because you knew what to look for, and it is not part of docs but an online tutorial, right?

Hi everyone. Is it possible to incorporate delay in ItoProcess?

@RolfMertig I think about that sometimes. I think part of it is that Wolfram hasn't set up the ecosystem to be particularly easy or obvious to extend, so people tend to just write little snippets, but the barrier to go beyond that is too much for most people. That prevents development-oriented people from really getting into it and I'd argue development-oriented people drive the popularity of even many scientific programming languages.

Also Wolfram's business model is terrible for getting large-scale adoption.

@RolfMertig I'm not sure I "believe" on the absence of Mathematica on the Tiobe Index, when compared to Maple (with MATLAB I would have no doubts, but Maple...)

@ChrisK On my field, free is generally more expensive... as we do consider our daily cost on the equation, which (un)fortunately pays for a license of Mathematica in almost no time... This also seems to be the case for many other softwares, as industry and commercial activity is driven by net gain, and yet, most companies use MS Office and Windows.

(keeping aside the duality between free and open)

@b3m2a1 but I do agree that the business model doesn't favor at all large-scale, as there's still no convenient way to deploy thousands (or even hundreds) of apps based on the kernel extended by our own definitions, without having to be under the CDF graphical umbrella, or the full Mathematica instance (and by consequence some sort of "over-dimensioned" license scheme) for all deployed installations (and yes... the cloud is not an option for me...)

@RolfMertig @P.Fonseca There is someone who recreated the Tiobe ranking and it came out that way, with Maple being much more popular than Mathematica, also for him. But if you remove the word "programming" from the search query used to compute the TIOBE index, then Mathematica comes out on top.

My personal opinion on why Mathematica is not used in the industry is because managers don't want to wait around while employees learn to use it. All the most popular languages are C-like and roughly follow the principle of least astonishment. Go has been the TIOBE language of the year two times. It's main idea is to be easy to use for anyone who has knows C like syntax.

The Google creators themselves say that they wanted to build something that was faster to learn, because Google had a lot of young developers but it took too long for them to become productive with C++.

@P.Fonseca I agree, but hard to convince grad students! Also, most people in my field do stats, so it's easier to keep using R for a little programming on the side.

Not a great success: FindFormula[Table[64 x/(64 - x), {x, 1, 63}]]

What would the Wolfram Language entries be for the "Coding Styles" section of this link? Also is anyone able to add them? en.wikipedia.org/wiki/…

Okay, so I need some help, and I don't think I can turn this in to a coherent question.

Wolfram was kind enough to give me an evaluation license of Mathematica for use with my website whereisroadster.com

I really like the plotting that I have seen from Mathematica, and I am interested in doing more with it.

I'm just not sure what it is that I want to do exactly with it.

The one that was initially pointed to me is WebMathematica.

That sounds cool, but I'm not sure how I would host it. My website has been known to have huge spikes in traffic from time to time, and while I think most of those are gone, I'm a bit nervous to have a hard commitment, not to mention I'm not sure how the licensing would go for such a server.

I know there is such a thing as a CDF as well, but that seems a bit tricky to use. I have 3 forms of graphs, and it would be nice if the data at least for these charts was common to reduce the usage of bandwidth. I could have one CDF I suppose and just initialize it differently to do the 3 different modes, I have no idea if that would be a good solution.

Any other options I should know about?

Hmmm... It seems like CDF requires the users to install a plugin?

Sigh. So it really is down to Web Mathematica. Unless there's some way to make the development platform work...

@PearsonArtPhoto How'd they give you that evaluation license? The development platform works on a "cloud-credits" scheme and you can embed objects deployed there into webpages.

So I could imagine making that work, but I'm not sure if that could be done for free.

I'm not worried about paying a small price.

I would be happy paying, say, $20-$50 a month, but not much more than that, assuming I can get this all to work right.

They contacted me and offered me an evaluation license.

Having Elon Musk tweet your website out encourages people to talk to you.

I like the idea of using Mathematica on my website, but the more I look in to it, the more complex, and expensive, it seems.

Even if they provide me a full license to use for free, which is possible, the website hosting would add up.

And with the number of visits I have had at the same time, well...

@PearsonArtPhoto How are you currently hosting your site? If it's a fully static and running in the browser you can keep that by embedding stuff deployed to Wolfram's cloud infrastructure.

It is fully static now.

Yeah, it seems like something using the cloud infrastructure is correct, and I'm starting to see how that would work.

I think it's possible to preserve that. One issue with their cloud infrastructure is that it's kinda buggy. If they give you the cloud credits you can make calculations run in an APIFunction and call them through JS. I'd run some small scale tests first though and haggle with them for enough credits to do this.

What types of calculations are you trying to use Mathematica for here?

Really I mostly want to use the plotting ability.

The plots on whereisroadster.com are somewhat limited, and it seems like they could be improved by some other means of plots.

I might also do some stuff like orbital dynamics.

@PearsonArtPhoto the APIFunction route should work for this, but I'm not entirely sure how fast it will be. It probably can't compete with something like D3, but for most things it should be fast enough I imagine, especially if set up well. Still, this is beyond the scope of any stuff I've done with it so I'm mostly guessing here.

Will do some playing with it, but the more I look in to this, the more I think that Mathematica isn't the solution.

I need something that works in Javascript.

@PearsonArtPhoto Yeah I agree. I don't think it's nearly light-weight enough for what you want to do. I'd go for D3 I think.

Right now I'm using Plotly, as I might have mentioned, but I'll look in to D3 as well.

I will consider using Mathematica for some of the back end stuff, but I'm not going to try to use Web Mathematica, it is just too much work.

@PearsonArtPhoto that's what I do. I use Wolfram's cloud as my web host and generate all my HTML and stuff entirely inside Mathematica, but I don't use the cloud in any interactive way.

Hmmm.

I probably won't use Wolfram as my web host, nor generate the HTML in mathematica, although I'll consider it.

I like the idea of using Mathematica, but... Sigh.

I've never really used it, so...

I have used Matlab, which I assume is similar, although Mathematica seems to have a bit more power

Yeah that makes sense. It's just a workflow that I wrote up because I use Mathematica so much. Do what's easiest. And in my experience that's generating graphics and doing data analysis in Mathematica but then using other tools for what it's bad at.

That's exactly what I would do with it.

Does anyone with expertise on undocumented magic know how some of the ZMQ socket features work in MMA 11.2? How can we open a subscription channel that other ZMQ capable external applications can subscribe to and exchange messages. Here is a question on this: mathematica.stackexchange.com/questions/156161/…
