Interaction Design Project 2012: Neverball

On July 11th 2012, participants of the Interaction Design course (refer to the HCI group website) at the Department of Computer Science of the University of Hamburg displayed and showcased the results of their projects. They developed concepts and prototypes of input mechanics for the game Neverball. This video is a collection of the results.

Streets4MPI (Parallel Programming Project)

This talk marks the official end of the Parallel Programming project.

We presented our results by explainig the algorithms and technical underpinnings of our software, showing visual examples and comparing runtime data for different parallelization scenarios.

Aspects of Software Reuse

Aspects of Software Reuse

Abstract: Despite continuous improvements of the tool support, creating software from scratch remains a costly endeavour. From an economic or a pragmatic point of view, it appears beneficial to strive to reuse, adapt and transform existing software as much as possible. This article provides an overview over some strategies towards that goal on the basis of chapter 16 of Ian Sommerville's book Software Engineering, supplements the contents of the book with the topic Open Source and discusses the reuse of software components with the help of Steve Yegge's "Rant" about Google and software plattforms.

This paper has been written for the Softwarearchitektur course. The topic (summarizing the book chapter) was supplied by the organizers, but was expanded with my own ideas.

My first free software

2011-12-23 00:35:36

Für Alles gibt es ein erstes Mal. Ich kann mich noch daran erinnern, wie ich das erste Mal einen Programmcode kompiliert habe. Das waren damals Turbo-Pascal-Schnipsel und ich erarbeitete mir im Selbststudium genug davon, um eigene kleine Spiele unter DOS erstellen zu können.

Paradoxerweise programmiere ich trotz Informatikstudium heute eher weniger als damals. Meine Webseite ist im Prinzip mein einziges Bastelprojekt, in dem ich mich austobe wenn ich etwas Erholung vom Universitätsstoff brauche. Ganz ungestört für mich selbst zu entwickeln hat auf jeden Fall seinen Reiz, umso mehr wenn die Besucher meiner Webseite dadurch auch noch tolle neue Features gewinnen.

Erst vor ein paar Stunden hat es für mich noch ein anderes erstes Mal gegeben: Ich habe gerade das erste Mal Quellcode von mir frei lizensiert und veröffentlicht.

Piwik

Piwik

This Lightning Talk was held in the KunterBuntesSeminar organized by Computer Science students in Hamburg, it was the first one of the session.

The subject was Piwik, a free and open source tool for website analytics. I explained the basic idea and showcased the possibilities for anonymization and data protection as well as other advantages of Piwik.

Making Of "Software-Wiederverwendung"

Making Of "Software-Wiederverwendung"

This is a timelapse recording of me creating the slides for my talk about software reuse, based on chapter 16 of Ian Sommerville's popular book "Software Engineering". Five to six hours of screen recording have been condensed to five minutes for this video.

Tools used: LaTeX, Kile, Inkscape, yEd (shortly), Firefox, evince and probably more. Running Ubuntu Linux 11.10.

Music: Approaching Nirvana with Bangers & Smashed, available on Bandcamp or iTunes.

recordmydesktop and OGV

2011-09-20 18:53:02

Just a small heads up to anyone doing any kind of screencast or desktop recording on a typical desktop Linux:

Usually, people will recommend recordmydesktop, which is a very cool program that's available e.g. in the Ubuntu repositories. It works really well and all, but I keep running into walls with the OGG/Theora videos that it produces.

I'm no expert on video encoding, but apparently recordmydesktop does some very fancy optimizations involving variable FPS and stuff like that, so the video files are quite small byte-wise. Unfortunately, this has caused problems for me down the line: I can play the files just fine in Totem (thus, gstreamer) or VLC. But as soon as I try to reencode them, all hell breaks loose.

Interaction Design Project: Neverball

Interaction Design Project: Neverball

In the "Interaction Design" course of 2011 at the Dept. of Informatics, University of Hamburg, students for Human Computer Interaction, Informatics and Business Informatics took part in a project centered around the game Neverball. This video presents the results.

Thunderbird and Notify OSD

Thunderbird and Notify OSD

This lightning talk was held in the KunterBuntesSeminar. I introduced the topic with the first slide and then showed live how to transition from Thunderbrid's own notifications to using Notify OSD (and also the indicator applet, incidentally) on a typical Ubuntu Linux desktop.

For the downloadable slides here, a summary of what to do has been added.
