for university I have to design and build an online auction website using GWT.
But the professor did not give us any material to study, do you have any guides, links or videos?
There are many resources on the web. A good point to start is: https://dev.to/ibaca/modern-gwt-first-steps-509k
To create a running GWT project, you can use:
https://github.com/DominoKit/domino-ui/wiki/Getting-started (see dominokit-cli)
http://www.mvp4g.org/boot-starter-nalu/BootStarterNalu.html (generating a Nalu project)
I would use Nalu (Disclaimer: I am the auther of Nalu) and suggest to use Domino-UI for the visual components (https://github.com/DominoKit/domino-ui) and domino-rest (https://github.com/DominoKit/domino-rest) for the client-server communication.
in case you need help, you can ask questions here:
GWT: https://gitter.im/gwtproject/gwt
Nalu: https://gitter.im/Nalukit42/Lobby
Domino related stuff: https://gitter.im/DominoKit/domino
Hope that help.

Recently I was reading an article about "Browser Internals" and suddenly this idea struck me.
What if I create my own Browser?
So, I have two questions with me.
Question 1:
Is it possible to integrate an Open source Web Engine like "Servo" or "WebKit" to my custom Browser UI interface created using QtCreator or Visual Studio?
Question 2:
Is there any other components that needs to be inserted between the UI created using C++(QtCreator) and Servo or WebKit?
Note:
I am a complete beginner to this field and these questions were asked in a curiosity to learn internal stuff. Pardon if the Questions were not standard.
Thanks :)
Answer 1:
Yes, it is possible. Browser engines have public APIs to provide a way to embed them. For example, the goal of this little project was to present how to build up your own UI interface (using Aura) and wire Chromium (browser engine) into that.
http://szeged.github.io/sprocket/
Answer 2:
If you prefer Qt technologies, then QtWebEngine will be the solution. The intent of this module is exactly what you have described: to embed Chromium engine into Qt applications with hiding its most painful parts and provide convenient API to customise your browser application.
http://doc.qt.io/qt-5/qtwebengine-overview.html
And there are several others:
QtWebKit: http://doc.qt.io/archives/qt-5.5/qtwebkit-index.html
CEF: https://en.wikipedia.org/wiki/Chromium_Embedded_Framework
You don't necessarily have to use extra layers between your application and a browser engine, but if you are a complete beginner, I would highly recommend that.
I'm trying to learn how to use Google's Web Toolkit (GWT) editor framework. I haven't been able to understand how I can use it through the documentation. The examples I've found online were not helpful for me to begin with. I would like to ask if someone can provide a simple working example.
The book GWT in Action, second edition has a chapter about the EditorFramework.
The sample code is free to download:
GWTInActionSamples
You should find working examples in chapter 9.
You can also look at the following sites for further reference, good examples to get your hands dirty with! Might not be a full blown examples, but definitely a good read to understand the concepts!

I want to create a vBulletin custom plug-in but I am new in vBulletin i don't know about the vBulletin. I have tried to download the plug-ins but only commercial user will download the plug-in.
There is no specific tutorial that you can follow to create a specific product, however there is a good tutorial from vBulletin which gives you a good idea on how to create a vBulletin 'product' that can be downloaded and installed by others.
But basically to create a product you need to learn some basics and you have to know, php, html, css, and have a understanding of how vBulletin works. Then take it and put it all together.
To get a good understanding, I would recommend modifying other people's add-ons to suit your needs. That's how I was able to get a good understanding of how vBulletin works and then all you have to do as you progress, is to ask the right questions.
The recommendations bellow are also supported by well know vBulletin coders.

HTML basic guide: HTML Tutorial - (HTML5 Compliant)

I am doing an app in which I require a business card reader I googled alot but BBY is the only solution which I was able to find out. Can anybody help me out with some opensource library which can be tweaked or used directly as a business card reader.
Please enlighten me on this.
you can look into the Tesseract open source engine... its pretty good for image processing.. i mean it will extract the text out of the image but then you will have to process it to extract name ,phone numbers and other details.
this guy has explained how to use it in iOS .. http://tinsuke.wordpress.com/2011/11/01/how-to-compile-and-use-tesseract-3-01-on-ios-sdk-5/
We started an open source project to build a Javascript library (based on the OCR engine tesseract.js for the OCR part) that exctract the relevant data from a business card based on heuristic criteria.
The library (BCR Library, available on github) is usable in any html project (included mobile cordova, phone gap or ionic projects) just including it via script tag.
The library doesn't have any external api call and fully works offline.
I think that you should give a try to Covve Bussiness Card Scan API. The quality of the result is great in various languages. You can check a comparison analysis of similar services here.
