Building a Document Translator for a Multi-Language Blog

Motivation

Multi-Language Blog Navigation

The idea for this project occurred to me while I was listening to my sister share her vision for her recently started blog: To create a platform where writers of different ethnicity can publish texts in their native languages and exchange their stories with people from all over the world. Conquering the language barrier and making the texts available at least in the three most prominent languages – German, English and Arabic – requires the involvement of translators who are fluent in at least two of the demanded languages. Anyone who has ever attempted to make a translated text sound natural knows that this is no easy feat and can take up to many hours of finding the perfect balance between literal translation and understandable text.

This is where I saw room for improvement. Nowadays, machine translation tools have reached a decent level of fluency, despite not being able to capture the intricacies of different linguistic styles. Combining them with people who have a basic understanding of the source language can help speed up the process and reduce the effort considerably. Continue reading

Building a fully scalable architecture with AWS

What I learned in building the StateOfVeganism 🌱

Final setup for the finished project (created with Cloudcraft)

By now, we all know that news and media shape our viewson these discussed topics. Of course, this is different from person to person. Some might be influenced a little more than others, but there always is some opinion communicated.

Considering this, it would be really interesting to see the continuous development of mood communicated towards a specific topic or person in the media.

AIRA Voice Assistant – A proof of Concept in virtual reality

Motivation

As part of the lecture “Software Development for Cloud Computing” we were looking for a solution, how a user can get basic assistance within our existing virtual reality game AIRA. The primary objective was a maximum of user-friendliness, while avoiding an interruption of the immersive gaming experience. It is also important to keep in mind, that the user is on its own and any kind of support from outside is usually not possible.

Moreover, considering that within virtual reality applications generally no conventional input devices will be available and therefore a keyboard is not an option. If we still following up this idea, many people may think next of an on-screen keyboard, as they know it from their smart TV at home, which might be operated by a game controller. Although such an approach would be contrary to a high ease of use and majority of implementations are quite crippled as well as hard to use.

So, what would be obvious and take all previous considerations into account? Simply think of something that each of us is carrying along at any time – the own unique voice. According to this we decided to implement a personal voice assistant into our game. In the following, it can be seen that the individuality of each human voice leads into a lot of difficulties we have to take care of.

In the following, it will be explained in detail how we implemented a personal voice assistant using multiple Watson serviceswhich are part of the IBM Bluemix cloud platform. Especially fundamental problems we run into will be discussed and then possible approaches will be pointed out.

VVS-Delay – AI in the Cloud

Introduction

Howdy, Geeks! Ever frustrated by public transportation around Stuttgart?
Managed to get up early just to find out your train to university or work is delayed… again?
Yeah, we all know that! We wondered if we could get around this issue by connecting our alarm clock to some algorithms. So we would never ever have to get up too early again.

Well, okay, we’re not quite there yet. But we started with getting some data and did some hardly trustworthy hypothesis of prediction on it. In the end it’s up to you if you gonna believe it or not.

To give you a short overview, here are the components that are involved in the process. You will find the components described in more details below.
Process overview

A view parts in short:
1. crawler and database – get and store departure information
2. visualization – visualizes the delays on a map
3. statistical analysis – some statistical analysis on the delays over a week
4. continuous delivery – keep the production system up to date with the code

Sport data stream processing on IBM Bluemix: Real Time Stream Processing Basics

New data is created every second. Just on Google the humans preform 40,000 search queries every second. By 2020 Forbes estimate 1.7 megabytes of new information will be created every second for every human on our planet.
However, it is about collecting and exchanging data, which then can be used in many different ways. Equipment fault monitoring, predictive maintenance, or real-time diagnostics are only a few of the possible scenarios. Dealing with all this information, creates certain challenges for stream processing of huge amounts of data is among them.

Improvement of technology and development of big scaling systems like IBM Bluemix it is now not only possible process business or IoT data, it is also interesting to analyze complex and large data like sport studies. That’s the main idea of my application – collect data from a 24-hour swimming event to use real time processed metrics to control event and athletes flow.

In this article explains how to integrate and use the IBM tools for stream processing. We explore IBM Message Hub (for collecting streams), the IBM Streaming Analytics service (for processing events) and IBM Node.JS Service (for visualization data).

Developing a Chat Server and Client in the Cloud

Introduction

During the Lecture “Software Development for Cloud Computing” I decided to develop a Cloud based Chat Application with the help of IBM’s Bluemix.
The Application consists of 3 separate Applications:

  • Chat Server: Allows Clients to connect to it, manages the Chat-Channels/Users and relays messages sent from a client to the other clients in the same channel.
  • Chat Client: The Client consists of a GUI where the User can connect to the Server and chat with other Users.
  • Chat Backend Database: A simple Database which records and provides the chat history of a given Chat-Channel via REST.

IoT with the Raspberry Pi – Final application – Part 3

In our final application, we have put together a solution consisting of four different modules. First, we have again the Raspberry Pi which raises and sends the sensor data using the already presented Python script. We changed the transfer protocol in the final application to MQTT, which gives us more possibilities in different aspects, but more on that later.

IoT with the Raspberry Pi – Node RED – Part 2

As already stated in the introduction to our project, we decided to create a Cloud Foundry-Application in IBM Bluemix. We used the boilerplate called “Internet of Things Platform Starter”. Using this boilerplate Node Red is deployed initially.

Node Red is a software tool for graphical dataflow programming. It was developed by IBM and is open source since 2016. Providing a browser-based flow editor it enables to wire together hardware devices, APIs and online services.
