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 am looking for a multi tenant solution with sugarcrm.
Please note that,I don't like to go with creating multiple Sugarcrms instances.
In fact, I want to offer a solution for multiple organizations with different contacts, clients ... etc.
I am using SugarCE-Full-6.5.14(Community Edition) version of sugarcrm. Is that possible with this version of sugar?.
I have seen several links about the same,but unfortunately i could not get a solution from those links..
Any one please provide some useful informations about the same or what changes i need to be made in this version to manage multiple organizations ?.
Thanks,
There are a number of reasons why it isn't a good idea to use SugarCRM, as-is, for multi-tenant purposes. See:
http://cheleguanaco.blogspot.com/2010/09/sugarcrm-101-how-do-i-manage-multiple.html
http://cheleguanaco.blogspot.com/2013/03/sugarcrm-101-multiple-businesses.html
If you really want to force it to work you would need something to keep the data segregated like SecuritySuite: https://www.sugaroutfitters.com/addons/securitysuite
But there will always be potential holes. It is best to just spin up a new instance for each customer.
Yes edaklij - It is very much possible to have www.xsw.com/x , www.xsw.com/y, www.xsw.com/z etc, what you just need is a webserver where www.xsw.com pointed to main root directory, and within that you have sub-directories x, y ,z etc. Now each of sub directory contains one complete Sugar instance, and you are done.

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

We're after a replacement for a DotNetNuke installation with a DynamicForms module by DataSprings.
Currently the problems are mainly performance related, but the fact that DynamicForms uses Postbacks on ASP.Net all the time renders it also highly susceptible to slow server response time.
We're after a Drupal module which would allow us to present the CMS user with a control panel where they could:
- create new surveys
- assign a target group for the surveys
- manage the questions:
- checkbox/radiobutton/combobox/open questions
- variations of the above - e.g. a combobox with a text field when "other" was chosen
- the support for data lists, e.g. "what state do you live in" with values stored in the database and managed separately.
- conditional questions (show/hide) further questions when a certain option is chosen
- grouping questions (hiding sets of questions at a time)
- scrapbook function (storing frequent questions and being able to easily copy them into the new poll)
- exporting the poll data along with selected attributes from the user profile
As you can see the requirements are huge, and we're looking for an Open Source alternative to the current solution, which would allow us to extend the module if necessary.
Drupal would be the platform of choice, but we're flexible in that respect.
I'd appreciate your suggestions of alternatives.
There is a similar discussion going on at Drupal.org. IMHO, Drupal just isn't perfect for complex surveys. Limesurvey is much better when it comes to different types of questions, conditional blocks, reusable question types etc. However in Limesurvey 1, the admin interface is awkward and theming/templating system is not great. Limesurvey 2 looks very promising, but it's in beta.
Your best choice should be a new drupal module integrating the LimeSurvey software :

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.
