Yet another Connected Vehicle Cloud Platform

Getting Ideas… write a User Story

When I thought about an idea for a project, part of the lecture “Software Development for Cloud Computing”, I had two related use-cases in mind. So I wrote down those high-level user-stories:

As a user who owns a non-connected car, I want to access some information about my car on my smartphone so that I know about the position of my car and additional information like fuel level, consumption or driving statistics.

 

As an employee who wants to drive a pool-car, I want to know where the vehicle is parked so that I don’t have to search on different parking spots around the building.

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

Web server with user registration and guestbook with image upload

Overview

The users access the website where they have the option to the view the guest book, register or log in. To register the user has to provide a username, an email address and a secure password (more than 8 characters, upper and lowercase characters, numbers and special characters). Then an email with a verification link will be sent to the provided email address. Clicking this link will enable the user to login.

Upon login the user can post messages in the guest book, which will be saved to the MySQL database. In addition to a text message the user can also upload an image which will be transferred to an S3 Bucket, which in turn will trigger a Lambda. Here the image will be resized to make it suitable for displaying in the guest book and it will be transferred to another S3 Bucket and permissions will be set to make in publicly accessible. The URL to this image will also be saved in the MySQL database.

How to build an Alexa Skill to get information about your timetable 2018 Version

Imagine a student who just got up. He knows exactly that he has lectures today, but he does not remember which one or even when it begins. So, he asks his Alexa device: “Alexa, which classes do I have today?’” His Alexa device is able to look into his timetable and answers: “You have five lectures today. The first lecture is Digital Media Technology and starts at 8:15 am in room 011, the second lecture is Web Development and starts at 10:00 am in room 135, the third lecture is Design Patterns and starts at 11:45 am in room 017. You can see more lectures in your Alexa app.”

This scenario is what we had in mind when we started to develop an Alexa skill which should be able to tell you information about your timetable.

Tweets by Donnie - Building a serverless sentiment analysis application with the twitter streaming API, Lambda and Kinesis

tweets-by-donnie dashboard

 

Thinking of Trumps tweets it’s pretty obvious that they are controversial. Trying to gain insights of how controversial his tweets really are, we created tweets-by-donnie.

“It’s freezing and snowing in New York — we need global warming!”
Donald J. Trump

You decide if it’s meant as a joke or not.

But wouldn’t it be nice to know whether the public is seeing this as a joke or whether it’s getting upset by it? That’s where our idea originated from. By measuring the emotions presented in the responses we can see what the public is thinking of Trumps posts throughout the day.

Building a Serverless Web Service For Music Fingerprinting

Building serverless architectures is hard. At least it was to me in my first attempt to design a loosely coupled system that should, in the long term, mean a good bye to my all-time aversion towards system maintenance.

Music information retrieval is also hard. It is when you attempt to start to grasp the underlying theoretical framework and submerge yourself into scientific papers which each yield a different approach for extracting some feature out of digital audio signals. It is a long way until MFCC starts to sound natural. I have been there.

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.

Supply Chain Management using Blockchain Technology – Hands-On Hyperledger (Part 1)

Motivation

Many of today’s supply chain management (SCM) solutions still involve enormous amounts of manual work. The procedures required for proper record keeping often rely on manual input, which makes them slow and prone to errors. Additional terms, such as price agreements, conditions that must be strictly adhered to, as well as penalties for neglection of the latter, rely heavily on the completeness and correctness of the recorded information.

The infographic “The Paper Trail of a Shipping Container”, published by IBM, outlines the challenge to improve the management with blockchain technology, using the global container shipping industry as an example.
