Bye Bye Flamingo

The last report for the Flamingo project has been submitted today. The final project review will take place next week and hence it is getting time to say bye bye to the Flamingo project. I truly enjoyed the four years of the Flamingo project.

Good Bye

About 10 years ago, we became Jacobs University Bremen and as a consequence of the name change we had to transition DNS names from to In order to not break things unnecessarily, we kept serving the zone but now the time has come to shut it down. We received DNS queries for after turning it off for a while but after some weeks queries for the retired zone seem to stop.

Switching from NanoBlogger to Hugo

I have always been a fan of static web pages. When I started to think about a personal web page in 2005, I ended up using NanoBlogger as my content management system since it allowed me to write blog posts in a terminal (over ssh) using my favorite text editor, it did not require much on the server side, and it was a rather cool shell script hack. The world moved on since 2005 and content management systems became really big and also quite usable (I can edit content on them easily even without my most loved browser plugin It’s All text!

Occasionally it is good to pull the plug

The Internet is everywhere. As educated citizens of the modern information age, we believe we know what we are doing when we sign up for online Internet services. But we (too) often ignore the fact that we also collectively work towards a world where without the Internet, we are nowhere. Back in a day, before the digital revolution, people were buying and thus owning content, nowadays we get content streamed but we do not own it anymore.

Streak-Running Experience

Every runner knows that variations are important; running always the same route at the same pace is not only boring but also ineffective from a physiological point of view. I am neither a fast nor an ambitious runner - I usually run distances around 10 km (sometimes less, sometimes more) and I do three runs per week. I prefer to run a mixture of new routes and well-known routes. I enjoy exploring unknown areas by running through them and I am used to travel with running shoes in my luggage.

Musings on the Loss of Privacy

I am using computers since the early 1980s and I am ‘on the Internet’ since the late 1980’s. Back then, it was clear that computers had limited character sets and hence I started to write my name in a format that computers could deal with easily. Hence I have two ‘names’ on the Internet and in fact a couple of additional ones that were created by software doing bad transformations and humans mixing writing styles.

Experiments in Computer Science

Research in systems-oriented computer science involves the implementation of prototypes and their experimental evaluation. It is not uncommon, in particular for young researchers (means students), to spent most of their time on the implementation itself, spending little time on the evaluation of the system. Of course, it is then often too late to discover that a proper experimental evaluation of a system takes lots of time and effort. I am writing this in order to help people to avoid falling into this trap.

Time for the Journal of Opinionated Networking Research?

I have just enjoyed reading a paper where the author reports about a number of measurements he did and draws very clear ‘opinionated’ conclusions from the facts presented in the paper. This was such a refreshing read and I started to wonder why I found this so refreshing. It turns out that most networking papers I read (or have to read) either have lots of opinion but only a very few facts to support them or the papers have lots of facts but the authors refrain from articulating a clear conclusion and a clear opinion from the facts.

NETMOD Working Group

I have accepted an invitation to co-chair the NETMOD Working Group in the Operations and Management Area of the IETF. Almost exactly five years ago, I have been in a similar situation when I was asked to co-chair the ISMS Working Group in the Security Area of the IETF. I am still co-chairing ISMS - lets see how long my engagement with NETMOD is going to last…

IETF Store Opened

The IETF has just opened a store where you can buy official IETF logo wear. This is an interesting new move towards IETF sponsorship since some of the money of each item goes to the IETF. I have no clue how much money this brings, but surely there are a few observations I like to share: The shop, likely located in the UK, knows shipping rates to Australia, Canada, the United Kingdom, the USA and of course worldwide.
