Interaction in the Blogosphere

2011-05-24, Dept. of Computer Science, University of Hamburg

Interaction in the Blogosphere

This talk was held in the course Computer-Supported Cooperative Work.

I started by explainig "blogging" as such and what it's about, then going into interaction patterns frequently found on blogs. Among those were comments and their structure, Trackbacks and Pingbacks as well as social media widgets. I ended with two scenarios concerning anonymous blogging and the use of blogs for knowledge management by enterprises, respectively, as well as a brief look at a possible future for blogging.

Software that I end up avoiding

2011-04-10 20:01:08

Having recently acquired a brand-new smartphone, I'm still fiddling around with the system, installing apps and configuring things. So far I'm really happy with it, a definite step up from my previous cell phone (and that one wasn't even that old).

Imagine my surprise when I found out that the new one has an office app installed on it by the vendor. Inspired by a semi-recent article on OSNews, I'd been wondering what a good mobile office UI might look like, so I was eager to have a look at this one that came free with my phone. It's called ThinkFree Office and supposedly it works really well. Unfortunately I never actually could look at it. How come? Because the EULA is completely friggin' ridiculous. And here's why.

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.

Tunneling with sshuttle

Tunneling with sshuttle

In this Lightning Talk, held at the KunterBuntesSeminar, I presented a small tool called sshuttle and compared it to other, more well-known software solutions.

The Department of Computer Science at the University of Hamburg uses, among other things, IP-based authentication for access control. This means that there are some resources, e.g. on the web, which can only be accessed from the Dept. of Computer Science IP subnet. To access these resources from home, it is necessary to create and use some sort of connection to the CS net. This can be accomplished by connecting to the VPN or by establishing an SSH connection. The tool I showcased, sshuttle, promises a new way to solve this problem by tunneling IP traffic through a simple SSH connection using iptables. This idea has several advantages over the alternatives.

Mehrsprachigkeit und Lecture2Go

2010-06-29 16:54:24

Schon seit einigen Semestern bietet die Uni Hamburg einen Service namens Lecture2Go an. Die dort Zuständigen haben Equipment und Know-How zur gelungenen Aufzeichnung von Vorlesungen und anderen Vorträgen. Dort findet man zum Beispiel auch die Vorlesungen zum Modul Softwareentwicklung 2.

Vor etwa einem Semester hatte ich mitbekommen, dass ein Kommilitone ein solches Lecture2Go-Aufnahmeset für einen Vortrag im KunterBuntenSeminar organisiert hatte. Das fand ich sofort spannend, weil ich viel davon halte, Wissen möglichst allen Menschen zugänglich zu machen, die Interesse daran haben. Eine Aufzeichnung wie die mit Lecture2Go erlaubt es, die Grenzen der persönlichen Anwesenheit zu sprengen und einen Vortrag zu einem späteren Zeitpunkt und/oder an einem anderen Ort der Welt mit zu erleben.

Introduction to Subversion

2009-08-28, Dept. of Computer Science, University of Hamburg

Introduction to Subversion

This rather short (20 minutes) talk was held by me in the Software Development practical course where I was supervised by Eugen Reiswich.

By humorously showing the pitfalls of software development in a team without source control, I engaged the audience in the problem that software like Subversion tries to solve. I then gave a very brief introduction on how it works and then spent a little more time on how it is used and what practices were relevant for our project.

The talk was a little on the short side (this was planned as such in consideration of the limited development time we had in the course), but was very well-received for focusing on the "why and how do I use it" rather than the "how does it work".

Project Natal

2009-06-24, Dept. of Computer Science, University of Hamburg

Project Natal

This was a 5 minute talk held by me in the Human Computer Interaction course conducted by Professor Oberquelle.

It's a short introduction into the then-known facts (and rumors) about Microsoft's Natal. Specifically, I briefly talked about the cameras and the technical setup. Half of the five minutes were spent watching the official trailer.

This talk happened a few weeks after the initial announcement of Natal, so there wasn's very much information available.

Free Software for Beginners

2009-06-16, VMP5, University of Hamburg

Free Software for Beginners

This talk was prepared and held by various volunteers (Alexander Beifuß, Kai Hildebrandt, Tim Krämer and me) for the "Bildungsstreik" event in 2009, where regular university courses were supplemented by talks and courses created by students for students.

In this talk, we introduced the audience to the idea of free software and its importance. Afterwards, we played a game of "guess which is copyleft" as can be seen on the slides.

RFID - Capabilities and Dangers

2008-11-24, Dept. of Computer Science, University of Hamburg

RFID - Capabilities and Dangers

In this talk I gave an overview of the status quo concerning RFID and related technologies.

Since it was conducted in the "Computer Science and Society" course by Professor Valk, there was a strong focus on social implications of RFID, possible erosion of privacy and lobby organizations, though I also briefly spoke about job opportunities for CS graduates. A short technical introduction for people unfamiliar with the technology was also given.

The presentation included a live demonstration of a portable RFID card reader, which was able to read RFID tags from students who courageously volunteered to have their wallets scanned.
