Idea

This Project Management Tool for GitHub is currently under development and the main idea is the following:

• Instead of managing 1000 issues as labeled list items you arrange them in a second dimension, in a table.
• One way to arrange the tables are typical story mapping boards, aka feature table.
• This second dimension not only adds overview, but it also reduces the amount of issues to compare at a certain pint in time.
• Drag’n’Drop eases managing issues even further.

Features

Easy Project Management • Drag’n’Drop to edit Issues • Hierarchic Issues • Issue Dependencies • Visualize your whole project instead of single issues • free for public Projects • No information gets lost, because it’s stored directly in GitHub.

Team

Currently I’m working on the project alone.

What is Meetup?

Meetup is the world’s largest network of local groups. Meetup makes it easy for anyone to organize a local group or find one of the thousands already meeting up face-to-face.

About this Meetup Group

This Meetup Group is about Software Architecture and Design and I founded it due to a lack of Meetup Groups on this topic. On our first Meetup I held a talk with these slides:

The post Software Architecture & Design – An Overview appeared first on Oliver Stadie - Portfolio.

Overview

As a lead developer I coordinated the technical development of a stand alone testing software. It is especially useful for the automotive industry. The tool itself is primary glue code for many third party libraries, which was developed in an enterprise environment.

Due to an NDA I can’t tell too much about it, but you can visit the official product page for further details.

Features

Intuitive User Interface • Model Based • Systematic Test Case Specification • Systematic Test Case Generation • Automated Test Case Execution • Test Objectives • Linking with DOORS (specification tool) • Find Test Coverage Gaps • Search Function • etc.

Technologies & Methodologies

• Project Management: Jira • Confluence
• Languages: UML • Java • XML • XSD • CSS • Scripting Languages
• Models and Methodologies: Statecharts
• Libraries & Frameworks: Eclipse RCP • EMF • OSGI • GMF • Many Third Party Libraries
• Automated Builds: PDE, Ant, Custom Scripts
• Automated Testing: JUnit, QF-Test
• Continious Integration: Jenkins, SVN
• IDE: Eclipse

Team & other Stakeholders

• Product Owner: corperate colleague located in another city
• Technical Lead: myself
• Development & Deployment: myself + 6 developers in 2 cities
• Testing: 3 Testers in 3 cities and 2 countries
• Marketing: 2 corperate colleagues located in another city
• Third party software developers: 5 organizaton with differently close contact
• Customer: 1 Customer with direct influence on the product features.

Idea

Testing Graphical User Interfaces (GUI) is done very differently in commercial and academic environments. In commercial environments GUIs are tested with the simple and convenient Capture and Replay method. Academically developed GUI test methods use powerful but inconvenient model based approaches on the other hand.

My approach combines both methods to a convenient but powerful GUI testing method. The basic idea is the following:

1. The user executes example sequences on a GUI
2. A Model of the GUI is Generated
3. Test Sequences on the Model are Automatically generated
4. The Test Sequences are automatically executed on the GUI

The GUI Models stay compact and clear because they use hierarchies and orthogonality.

A systematic combinatorial approach generates the Test Sequences. This keeps the sequences complete but lean.

Features

Convenient but Powerful GUI-Testing • Capture-&-Replay Approach • Model Based • Systematic Test Sequence Generation • Automatic Model Generation • User Friendly GUI Models • Complete but Compact Test-Sequences • Test Arbitrary GUIs

Prototype

As part of my final thesis I also developed a prototype. The prototype is a Plugin for the commercial testing tool TESTONA. You can see it in action here:

Technologies & Methodologies

Context

This was a self organized project as an employee in the Berner & Mattner enterprise.

To realize this project I worked together with many other teams. I modified and integrated parts of their work into my GUI Testing Tool.

Details

I released a scientific paper   as part of this project. I also released the final thesis  and the final presentation  (in german).

Context

Blubber was developed on Paypals Battle Hack within 24 hours with the following restrictions:

• Use Paypal: The Paypal API had to be used by the final Software.
• Hack for Good: The app should improve the world or humanity somehow
• Local Range: The app had to be useful in a local area, i.e. your city or district.

Our team consisted of three professional developers.

Idea & Features

The motivation, idea and features of Blubber where presented in a 2-minute-presentation on the BattleHack:

Technologies

• Languages: html5 (JavaScript, HTML, CSS) • Java • Python
• Libraries & Frameworks: PayPal API • jQuery • bootstrap • Underscore • Java Servlets • Google App Engine • jQuery.qrcode
• Automated Builds: Maven • Gradle
• Automated Testing: JUnit • mockito
• Version Control: GitHub

Context

One Idea of Augmented Reality is the mirror below. This mirror shows an altered version of you. Thus it allows you to select your clothing in a menu. You don’t need to change it in reality.

One component of this augmented mirror is an algorithm to analyse the real clothing.

I developed an algorithm which analyses the structure of clothing and fabric to find patterns.

Idea

The algorithm takes an image of the clothing as input and extracts the structure (mesh) and texture seen in the image.

Extract the Structure (Mesh) of  an Image

Extract the Texture of an Image

Using this structure new textures could be applied to the structure to complete the mirror.

Details

I published the complete student research paper  (in german).

Context

This small app was developed for demonstrating WebGL in a Computer Graphics course. Back then WebGL was very new and we had to install pre-alpha nightly builds of Firefox, since no Browser supported it.

Our team consisted of two students.

Idea & Features

The idea, features and technical implementation of Wikip3dia where presented in short presentation (in German):

Background

The Idea was to merge the information of multiple sensors (acceleration, pressure, camera, etc.) instead of using every sensor on it’s own, to improve the grasping and walking abilities of humanoid robots. Also additional sensors where added.

Technologies

• Hardware: Nao Robots, additional modular sensors (e.g. acceleration)
• Software: C++

Results

The research resulted in promising new approaches for adaptive walking an grasping. A detailed paper on one of the grasping approaches was released: 

Nao Robot grasping objects of different weight and stability using the same adaptive algorithm and additional sensors.
