Functional reactive programming (FRP) is a variant of reactive programming for the development of user interfaces based on the functional paradigm and a strict set of basic operators. In contrast to reactive frameworks, such as RxJs, using FRP enables a developer to define a pure area in her code in which some error classes, typical for event-based architectures, do not occur. Sodium is an FRP-framework, which is independent of a specific GUI-framwork and supports several different programming languages. Here, we describe how to use Sodium together with Angular.
Given the browsers running on smartphones (and increasingly also those running on the desktop), all the “new” input types coming with HTML5 become increasingly important. For instance:
<input type=“time“ …
makes iPhone, Android et al present an optimized way of selecting a time / duration:
is a collection of examples, tutorials and best practices to develop mobile clients integrated with JBoss middleware. It aims at providing solutions for mobile clients to deal with typical requirements in enterprise applications, such as security and availability. Such mobile applications range from native clients (e.g. Android, iOS) via hybrid apps (with native and web components) to pure web apps (providing the highest portability but generally being less adapted to the target environment). In this post, we focus on a web-based mobile client and demonstrate how to develop a simple blog application where users can create and comment on blog posts.
akquinet tech@spree has published a technology radar analyzing the trends of 2011–2012. It provides an overview of the evolution of practice in the Information Technology sector in 2011 as well as a forecast for 2012. It is the result of one year of analysis and synthesis performed by the Innovation department of akquinet tech@spree.
The technology radar captures the output from discussions, experiments, projects, and feedback from customers and developers. It synthesizes the results to inform global technology strategy decisions. It focuses on new technologies and methodologies with a high level of attraction. This document does not aim to provide an in-depth presentation of each technology, focusing instead on conciseness and highlighting the trends and state of the practice.

In one of our last projects, we built a platform independent desktop client completely based HTML5 for the UI. HTML 5 provides a powerful way to build UI. Coupled with JQuery and H-UBU, we have developed a pretty exciting UI. One of the issues faced during this development was the management of the user interactions:
- How to report info or error to the user without breaking the interaction flow using the jquery-toastmessage-plugin
- How to explain to the user, he has to wait a couple of seconds while hard work is done in the background without too much frustration using the jquery-waitingpopup-plugin
