I improved usability by reducing it to one input text field and two buttons for two functionalities. On the front end I used "formaction" attribute in buttons instead of "action" attribute in the form. So I reduced everything into one form. In the backend, it was a bit more complicated. I needed to differentiate between different types of input and gather different classes of the two functionalities into one class. This helped remove code duplicates and made the code easier to understand. In the end, the usability of the web page improved greatly and the backend code was also improved.

Improving usability of input forms in web applications
In the web application I am developing, I had a barcode input text field and a URL input text field for two different functions of the application. This resulted in 4 text input fields and 4 submit buttons. The layout of the web page became confusing for new users and clattered. I needed to reduce input fields in the front end but also in the already implemented back end.

How can i create fast and easily a web application using java (and MVC)
Using Servlets directly in an application server is not flexible enough and too much code and too complex for simple tasks like providing a webservice interface (REST/SOAP)
The solution should contain everything needed to create a new project and describe the concepts of the used tools/frameworks.

Deploying a Haskell web application to the Cloud
We want to expose our logic that is programmed in the functional programming Haskell as a web service and need to deploy it as a public web service. For this we want to use a PaaS (Platform-as-a-Service) vendor, i.e., 'Cloud hoster', in order to publish this web service with minimal configuration.
How do I implement a custom "paging" script for a variable number of items?
A very common problem in web programming is to implement paging. Paging is required whenever there is an undefined amount of items (usually queried from a database) with a maximum amount of items to be displayed on one page. If there is more than one page, there must be a possibility to navigate through these pages while each page displays the desired amount of items.
An example will demonstrate the problem:
State:
- You have a category containing 23 products to be displayed in the category overview of your webshop
- A single page should display a maximum of 8 pages for design and usability reasons
Now we have to calculate the number of pages, the number of products to display per page and display everything to the user.
This case will result in 3 pages: Page 1 will display the items 1-8, Page 2 will display the pages 9-16 and Page 3 will display the items 17-23.
Please show a general algorithm for this problem.
