Anyone who's tried to study mathematics using online resources will have come across these Java applets that demonstrate a particular mathematical idea. Examples:
http://www.math.ucla.edu/~tao/java/Mobius.html
http://www.mathcs.org/java/programs/FFT/index.html
I love the idea of this interactive approach because I believe it is very helpful in conveying mathematical principles.
I'd like to create a system for visually designing and publishing these 'mathlets' such that they can be created by teachers with little programming experience.
So in order to create this app, i'll need a GUI and a 'math engine'. I'll probably be working with .NET because thats what I know best and i'd like to start experimenting with F#. Silverlight appeals to me as a presentation framework for this project (im not worried about interoperability right now).
So my questions are:
does anything like this exist already in full form?
are there any GUI frameworks for displaying mathematical objects such as graphs & equations?
are there decent open source libraries that exposes a mathematical framework (Math.NET looks good, just wondering if there is anything else out there)
is there any existing work on taking mathematical models/demos built with maple/matlab/octave/mathematica etc and publishing them to the web?
You might want to look at Wolfram demonstrations, and at the mathematica web player. This lets you take a Mathematica file and run it from a browser, and the demonstrations site already has thousands of demonstrations.

I am trying to write an app that should ideally work on multiple platforms. Most importantly, it should become a webapp, but also be usable as a desktop solution for windows. (Potentially Iphone/Ipad App, but I want to start small)
That said, I thought about using kivy and it seems ok overall, however it is important to me to display data from sqlite databases. The databases are nothing special or overly complex, just containing data on let's say customers, employees and financial (banking) data. I want to add data and display it as tables or graphs. That is basically the whole functionality relating to the GUI.
I realized that the table widget KivyMD seems to be the only one I can use in that regard. It occurs to me, that the PyQt6-table funcionality is much better though.
I now realized though, that I cannot make a webapp with neither PyQt6 nor Kivy. Unfortunate.
So it seems I have to choose webapp or desktop or mobile app.
As webapp is the most important one, which framework should I use?
And no, I do not want to switch to Java Script :). I want to stick with Python for now. I don't have time to learn Java Script at this time, maybe later.
Any feedback would be appreciated.
Best
Ben
See above :)
I tried Kivy and PyQT.

Markus Malessa has provided some fantastic answers to Goole App Maker questions here on Stack Overflow. However, App Maker will soon be decommissioned. What will be the preferred alternative for App Maker experts like Markus?
I appreciate the call out although I would not necessarily consider myself an ‘expert’ by any means. I do have to say that the initial choice for AM was largely due to the fact that it was part of our G Suite subscription and I was somewhat familiar with Google Apps Script and HTML/CSS due to some free standing app development using the HtmlService. Given that my background and education is actually not programming related at all I would consider myself to be the target market for these types of programs were little to no code is required.
Unfortunately the reality is that my place of work never really committed much funding to this project outside of my time and more so this was probably what some coders would apparently refer to as their 20% project. So really at the moment I am not sure yet where I will end up after this. I’m afraid though that unless we decide to pony up some funds for something else we will be back where we used to be before this without a lot of functionality.
Anyway best of luck to all citizen developers that took a plunge into App Maker, you guys are all great and it has been a pleasure providing feedback to you all.
I recommend using Angular, since it's also based on JavaScript.

I would like to know whether there any drawing tools available to map a given use case solution in terms of EIPs. There is a stencil available for MS Visio and a SVG alternative for OpenOffice. The shapes in the stencil is good but does not seem like the best graphics for a presentation. Any alternatives available for drawing EIPs? Thanks in advance.
diagrams.net has a set of EIP stencils built-in. I'm not sure if it addresses the issues in the question, but the tool is free. (I'm a developer on the project).
[]
Btw you could automate that. Check this:
http://camel.apache.org/visualisation.html
Use camel:dot maven goal
I've created an OmniGraffle EIP stencil years ago for the book Spring Integration in Action. I pushed it to Graffletopia, but I cannot find it there quickly. Let me know if you are interested in the OmniGraffle stencil and I'll search a bit more.
What is wrong with the stencils? Those are simply the shapes presented in the book Enterprise Integration Patterns. Looking at a presentation from the author of the book, I don't think the shapes look bad in presentation: http://www.eaipatterns.com/docs/jaoo_hohpeg_enterpriseintegrationpatterns.pdf.
I am not aware of any tools to draw EIP scenarios other than say Visio, Open Office Draw or similar tools. There are some IDEs to create routes (Fuse IDE and Talend Open Studio for instance), but these are really just to create runnable EIP implementations, not for presentation.
Late to the party, but Lucidchart (online cloud-based diagram tool) has an Enterprise Integration Pattern stencil, too.

I was given the task to create statistical reports and integrate them to an asp.net application (Webforms) connected to a MySQL DB.
I was looking at this question. However, the accepted answer is about SQL Reporting Services (I am using MySQL), and the most voted answer lists different tools (Crystal, ActiveReports, XtraReports Telerik, Versareports) but suggests they are all evolving and it was in 2009.
So, what options do I have at the present? Which one would you recommend me? Why?
If you want the quick and dirty, easy to use, and fairly flexible option, then ActiveReports still gets my vote. The most extensive is Crystal, but you have to really need the extra bang to warrant it's use, at least IMO. Telerik fits in between (if you are really familiar with their other UI controls, it is not a bad option, however, as the learning curve is greatly shortened).

I've been interested in Visual Programming Languages (VPL) for a while. However I've hardly seen any environments that can be used for practical projects such as Windows apps or web services.
I've heard of the following:
LabVIEW - electronics and instrumentation
Microsoft VPL - robotics
Game Maker - games
Google App Inventor - Android apps
Tersus - web apps
Are there any other VPL environments that generate executable programs and can be used for practical applications?
Probably a bit too late for this answer, but I'm interested in the same thing and for anyone else might read this and find it useful.
Here is a new one just for creating windows applications, it's called Korduene, however beware it is alpha just now.
You may have a look at the WPF based TUM.CMS.VPLControl
I don't know if it is practical enough for you but you can have a look at Thyrd, which was recently featured in the last Emerging Languages conference:
http://thyrd.org/
It is not just yet another visual stuff, there is really something there
Yahoo Pipes has a somehow limited scope, but I suppose it is one of the more popular examples of visual programming tools that are really used in practice.
DRAKON Editor
http://drakon-editor.sourceforge.net/
It generates code for compilation or interpretetion, not actual executable.
It it supports visual programming in several programming languages, including Java, Processing.org, D, C#, C/C++ (with Qt support), Python, Tcl, Javascript, Lua and Erlang.
Why to use DRAKON than other diagramming systems?
No line intersections. You will never find in DRAKON diagram two or
more lines intersecting each other! Not seen in other diagramming
systems!
Silhouette structure. It allows to break one diagram in to several
logical parts. Not seen in other diagramming systems!
No slanting or curved lines. Only straight lines with right angles.
Icons are placed only on vertical lines.
Branching is done in a simple, visible and consistent way.
Each diagram has one entry and one exit.

i recomend Outsystems for .net/java , it´s a great app Outsystems
