I have read a good dozen of articles (including ones from stockoverflow), slides and tried samples from the Apache. I'm a back-end Java developer, still struggling with client side part.
My task is simply a build To-Do widget and be able to store data created "Tasks" in db. Could anyone share some good example how to do this? In seems server-side REST works, nevertheless I don't know how to connect this a widget so that is doesn't persist data.
Thank you in advance.

With a colleague of mine, we're building an app written in Dart with Flutter on Android Studio. We've arrived at the point where we need to start integrating a database to collect and send user filled data, and so we chose MongoDB which will be integrated into Docker so that our app is ready to function on multiple devices. Since we will have many users and each of them will be entering their own data, we have a lot of parameters to take into account so we're creating a JSON skeleton to map out the structure of what data goes where. The obstacle is we have no clue what the best way is to approach MongoDB-Docker integration with our Android Studio code, as it is our first time using MongoDB and Docker. Any good tips or resources that could put us on the right track ? Thank you
Hi your real question should be : what will you use in beetween those two ? You should (I guess) create an API to simplify and securise your user-DB interactions.
If you're not familiar with those principles a quick reasearch should help.
If you want to continue without any API, you should put many effort into having a VERY clean code as your app will have a lot of information inside its source code and proceed to create a documentation. Also you could use an ORM.
I want to consume kafka stream into mysql using Python; on top if which I want to build a realtime web based (web app) dashboard that will automatically be refreshed (ajax) on each data insert in the database.
After some searching, found a suggestion that ajax is not good for this purpose.
This post said websockets are better than ajax in terms of Performance.
Because I am not sure on whats the best way to achieve this So your expert advice is needed.
Thanks.

Pretty-please find someone among your peers who can save you from yourself. (And is there any possible way that I can say this to you, such that you can "save face?" I can't think of any.) I'm not-at-all trying to have public fun at your expense. Please – "talk immediately to your manager. (S)He, surely, can help you."
I am certainly not an expert in this field, however my company uses Elastic/Kibana to read in from Kafka topics and display the data on a dashboard. This is just one of many routes you can take, but it works very well for us. You can read a little more into it here:

I'm new to webdev and I'm trying to use passport for registration/authentication on a site I'm setting up. I'm also going to write an application in node later on that will be using some of the user data (users will need to provide an API key for an account on another site that I will use to pull data into the application).
At the moment, the main issue I'm having is figuring out what goes where. I've found plenty of resources that explain how to create an app using passport, but nothing shows how it would be incorporated into your website or where the files should be in relation to your website. I'm relatively new to Node.js, and while I've written a few small applications I have never hosted them anywhere.
Bonus question: I'm using MongoDB with passport and I was also planning to use it to store some JSON my application will be receiving from API calls. However, I wanted to use MySQL to store some data as well. More specifically, I'm planning to save the raw JSON then I'll create a relational database out of the data I need from the JSON and then keep the rest in MongoDB for easy access. Is this common/smart, or should I focus on keeping everything in my MongoDB? I'm relatively new to NoSQL.
Thanks in advance for any help.
I would reference this tutorial. I just recently used this to help myself with a new application. Also there is an example of the same thing but in SQL here. So not sure what you mean by " where the files should be in relation to your website". The information related to to authentication should go in your database.
To your "bonus question" you can use two databases. The key here is to ask yourself why and what are the true needs for data, and how is this data accessed and used. From ground up I would like one and stick with it. If at some point later you realize a certain type of data would be better in a different database then you can add it.
Side note: look into an IDE such as webstorm to help you out.
I am working on an app in visual c++ which requires data to be accessed from a database which can be edited so that every time there is a modification to the data I do not have to resend the app as it will automatically update, it is also required that this is a desktop app.
I am currently using MySql however for this to run constantly I will be needing a server which for a single simple app wont really be worth purchasing, so I started thinking of alternative methods and thought to myself there must be some method of reading directly from a website or online database, am I correct in thinking this? If so could someone please explain how I would achieve this?
Also, I have purchased phpmyadmin in the past so if there is any way I could connect my visual c++ app to a database from this then that would be great.
EDIT: Note, this app relies almost entirely on the database as it is just 3 combo box's and one text field all of that values for which come from the database.
The following response is assuming that by online you mean on the web.
You cannot exactly 'connect' to an online database with C++ (or anything outside of that server hosting the database).
What I would do is create some PHP API's that you can POST to with libcurl via C++. You can both send and receive data this way.
I am doing a Web project, where I am using HTML5 and Django to store database in sqlite3. The part being, since I had to use python, I installed mod_python for apache2. Now the thing is I went through many sites for head start to store the data and retrieve it. When I check in google related to how to use mod_python I did get certain information on how I can send a request to a .py file and then execute it. But with Django documentation providing a tutorial which is to develop a polling webApp, I am not finding it measurable to the part I am trying to achieve.
I want to send the request from an Html file where I have a search box and some radio buttons, to Django through Apache2 (mod_python) and then access my database in sqlite3. Please could anyone give me brief idea on whether I am doing it right? Also if yes, can u give me a hint as in how can I send the request from HTML file to the database from Django and mod_python being used? I am a bit confused with Django tutorial.
Please if anyone can just let me know what exactly I should do! Or if any link with a proper guidance would be of great help.
Thank you.
Well, for starters, if you can install and use mod_wsgi instead of mod_python, you should -- mod_python hasn't been supported for years. I'd also strongly recommend that you use anything other than SQLite for a production web application -- SQLite doesn't cope well with multiple simultaneous transactions.
If you're stuck using mod_python, then see the Django documentation for using mod_python.
Once you've got that working, the rest of your questions can be answered by the Django Tutorial, particularly part 4, which covers the use of HTML forms with Django views and templates:
