By now, almost everyone has heard of them or even used one themselves: Digital health applications, for example, are apps that can be used to treat illnesses from the comfort of your own home. Whether it’s for recognising endometriosis or, as in the case of Lena’s master’s thesis, an app for pelvic floor training, the choice is diverse.
We spoke to Lena about how attractive such so-called DiGas are ultimately designed for end users and how gamification can even help users to use them better and more regularly.

Quickstart vaadin (mobile) applications with Vaadinator – part 1: Introduction

| akquinet tech@spree

Vaadinator generates a vaadin-based User Interface (both mobile and Desktop), backend and testing facilties from an annotated Domain class. It borrows much from the Domain Driven Design idea. Our intention is to get people productive with vaadin and excited about vaadin – even those who never worked with it before. Vaadinator is free and open source (Apache 2.0-licensed).

AngularJS in WARs – The Case of the Session Timeout

| tnfink

Artikel in deutsch ⤴︎

AngularJS is a great framework to build modern web applications. Java EE offers a rich and powerful environment to build reliable, scalable, and secure server applications. The combination of both worlds is straight forward: The web archive (WAR) contains all the HTML pages and the JavaScript code. The access to the server is done using JAX-RS.

Also the access control can be implemented using the standard Java EE tools. Using form-based authentication, a user first has to enter login and password before he can access the web pages. In addition to the web pages the servlet used by the AngularJS application can be secured in the same way.

That should solve all problems, am I right? Almost. What is not covered by default is the handling of session timeouts. When a session times out the user is redirected to the login page to establish a new session. This is fine for a human user. An AngularJS application can get quite confused. It access the server in the background, expects a JSON response, and receives instead an HTML page. Here, we show a solution for this problem.

Interactive SVG with AngularJS – Part 2

| Karsten Otto

When developing mobile web applications with responsive design, SVG are a viable solution for flexible images.
AngularJS in turn enables the wrapping of complex UI logic into custom HTML directives, resulting in clean and maintainable modules.
The combination of these technologies provides a good basis for interactive control and status elements. It is suitable both for building highly complex custom controls, as well as covering simple use cases in a generic manner.

Part 1 of this article explores several methods of employing SVG as flexible images in a cross-browser compatible manner.

Part 2 describes the use of AngularJS to construct custom control and status elements by manipulating SVG images.

Interactive SVG with AngularJS – Part 1

| Karsten Otto

When developing mobile web applications with responsive design, flexible images for interactive control and status elements pose a particular problem.
SVG offer a viable solution: They are much smaller than bitmaps of comparable size, and can be manipulated through their DOM API.
AngularJS in turn is well suited to wrap complex UI element logic in custom HTML directives, resulting in clean and maintainable modules.
Combining the two sounds attractive, but involves a couple of stumbling blocks to avoid.

Part 1 of this article explores several methods of employing SVG as flexible images in a cross-browser compatible manner.

Part 2 describes the use of AngularJS to construct custom control and status elements by manipulating SVG images.

Clean Objective-C: Private Methods in Objective-C

| akquinet tech@spree

According to the TIOBE Programming Community Index (March 2013), Objective-C is the third most-popular programming language, behind Java and C. This is not surprising, as Objective-C is used to develop the thousands of Mac apps and 775,000 apps for iPhone, iPad, and iPod touch that are distributed via the App Store (Apple, as of January 2013). With more than 40 billion downloads, getting apps on the market as quickly as possible is highly attractive.

Unfortunately, the software’s (internal) quality often suffers from a short time to market. If the product’s lifecycle is longer than expected and technical debt is not paid off, development costs rise continuously. However, it is not that hard to build quality into the software right from the beginning. The new Clean Objective-C blog post series will demonstrate this. So, let’s get started… Continue reading →
