Something new on the net:

My official personal website is up today. Its initial purpose was to provide information about me and my activities, and thus, it is expected to be very static. However, this site is open to new roles in the future.

1st year of Norway chapter

It has been a year since I first stepped my feet on Norway‘s soil. Many events happened during the last one year, adding new experiences to my personal and unique life-experience library in my mind. However, it is sometimes difficult to direct the memory pointer to the correct storage point inside the memory repository, and thus, copying them to the outside world (from my brain’s perspective), in this case a weblog, may ease the searching process when in need. The bad news is that one year is long enough for me to forget many details. Thus, the granularity may not be so high.

I have been living in Grimstad, a lovely small town in southern tip of Norway, since I first came to Norway in November 2010. The winter may look somehow gloomy for some people, but the summer is definitely enchanting, to a point that I felt I wanted it to last forever. This is in particular true especially since I live in an apartment by the sea. The beach is an excellent place to relax during the mid of year season with a very beautiful scenery in the surrounding. The only downside I experienced during the golden season of the year was the fact that the weather was a bit unpredictable. When rain came, the temperature could drop suddenly to a situation where I needed more layers of clothing than just wearing a mere t-shirt.

I was busy writing project description related to my work during the first couple of months of stay in Norway. I was quite new in the research arena, and I found being employed as a research fellow was quite tough. But hopefully the initial hardships will yield sweet fruits in the future. My research project proposal was approved around February 2011 by the research education committee, and I started to conduct the planned steps. As part of the PhD programme, I had to take 30 ECTS credits of courses during the entire lifetime of the contract, and thank God I have completed 25 of the projected 30 credits at the time of writing of this post. The first year was not that bad as I managed to publish two papers at IEEE-channel conferences, although I must admit that the papers were not of high quality.

In mid March 2011, I was invited by one of my supervisors to take part in a study tour to Edinburgh, UK. This trip was mainly a visitation to several partner institutions in the UK which had conducted some collaborations with the university (my current employer) in the past.

In late March 2011 I travelled to Oslo for attending a block course which lasted for several weeks, and in mid April 2011 I went  to Kjeller for a block seminar which lasted for several days.

In late May 2011 I travelled to Aachen, Germany, to fetch my left luggage in my previous apartment. My sincere thank you to my previous flatmate as well as friend who stayed in my old room. Congratulations to him as well for landing a high-profile job at Facebook‘s HQ in the US.

June 2011 was quite a busy month since I had to travel to Missouri, US, for presenting my first paper, and continued with another trip to Lesbos, Greece, for attending a mandatory summer course in Philosophy. A paper deadline by the end of June made things look worse, but in the end I managed to go through all hurdles on my way.

In July 2011 I visited Indonesia and met my big families and old friends.

In late August 2011 I presented my work progress in a PhD forum at UiA.

In early September 2011 I presented a poster in another PhD forum at UiA, but this time held jointly with Mechatronics department. Soon after I presented my second paper in Gjøvik, Norway.

In mid September 2011 I had the chance for visiting Stockholm with some friends for several days.

In late October 2011 I presented my latest work progress in a workshop in Copenhagen.

And at last, I was born in November. This means I am a year older now. I do hope that I will be wiser, smarter, and stronger. Hopefully the road ahead will open up a way for me to taste more interesting experiences, and hopefully good things will come my way.

Dafferianto bids farewell to Germany, Aachen, and everything in between. Auf Wiedersehen Deutschland!

This is my last day in Germany (most probably) for this year. I will leave for Norway tomorrow morning, departing from Düsseldorf’s international airport. According to the itinerary, I’ll have a flight transfer in Oslo before arriving in Kristiansand. I haven’t been to Norway before, therefore, I do really hope an adventurous journey will lie ahead of me.

I’d like to thank everyone in Aachen who, directly or indirectly, helped me through my study in particular, and daily life in general. My apology for any wrong doing. I will definitely miss you all.

Auf Wiedersehen Deutschland!

Last (official) working day at Ericsson Eurolab

Today, September 30th, 2010, is my last (official) working day at Ericsson Eurolab as an intern. I bought some cakes and invited some employees of the research department (I guess around 30 people joined) for a small farewell cake session in the afternoon (at 3 p.m.). I hope they enjoyed the cakes 🙂 I and my colleague borrowed small plates and forks from the canteen with our limited Deutsch, and fortunately the lady understood us 🙂

As most goodbyes, I felt sad to leave my workspace. But I know it’s time to start anew. I have gained quite some experiences with Ericsson Eurolab (couldn’t believe that I was involved in supporting the Mobile World Congress 2010 demo showcase), and I believe that I’m smarter today than 1 year and 2 months ago when I joined the company 🙂 Many thanks to God and my bosses who gave me this opportunity at the first place, and also other colleagues for the great working hours spent together. I hope we’ll still keep in touch, and perhaps we’ll do some projects together in the future 🙂 Many thanks to my girlfriend as well for supporting me through the hard times.

I experienced both Ericsson sites in Aachen and Herzogenrath, including the moving process. Below are some pictures that I took from outside of Ericsson’s premises.

1+ year has passed….

It has been more than a year since I last posted an entry to this blog. The days were packed with constant pressures, and the nights were (almost) always long (including weekends). A natural consequence of my very own choice: master’s thesis + student helper job at Ericsson Eurolab. But I’m happy that I made it through. Not only have the pressures given me unique experiences, but also a good lesson: how precious to focus on one thing is (Seriously, I mean it…. Happy are those who can focus only on their theses or jobs, not both 😛 ). It would be really great to have some leisure activities such as playing a video game or youtube-ing after work hour. I didn’t. It was mostly technical stuffs that I was in charge of during work hour, and after reaching home I should think about other comparable brain-intensive technical stuffs for the thesis, struggling to finish before the deadline’s date. Now I’m quite relieved to have obtained my masters degree. I was officially graduated from RWTH Aachen University just one day before the deadline 🙂 . Yes, for the sake of coolness, I can proudly introduce myself anywhere: Yohanes Baptista Dafferianto Trinugroho, M.Sc. Haha…. In addition, a paper incorporating some parts of my thesis work was accepted in NGMAST 2010 conference.

My decision to do both the thesis and student job was not taken lightly. I was financed by the European Commission with the generous Erasmus Mundus scholarship thoroughout the course of my study, but only for 2 years. I went back to Germany from Italy for the thesis in my 4th semester, and couldn’t manage to finish the thesis within that semester. That means I had to extend for a semester without any financial aid. This situation (somehow) forced me to do a part-time job, and thank God (also my bosses), I was offered a position at Ericsson Eurolab. With their kindness, I was even offered a Ph.D. position that I will undertake in the foreseeable future.

So, let me write a bit of what I did in the past one year as  a log so that I won’t forget them myself in the future. Just briefly 🙂

I travelled to Amsterdam for a 2-day trip with an ex-Trento classmate in June 2009. We visited several famous spots, including Van Gogh museum (I was alone for this one actually), Madame Tussauds wax museum, Hard Rock Cafe for a drink, the Red Light District 😛 (only sight-seeing), and a cruise trip.

In August 2009, my EuMI senior (an Indonesian) visited me in Aachen with his friend, and we went to Liege for a day trip. I remember we took a nap in a small garden for about 30 minutes or so.

Christmas break has always been a good time to rest. I optimised 2009’s Christmas break for a 1-week trip to Rome and Paris with a friend. We attended the Chrismast eve’s evening mass lead by the Pope himself in the Vatican city’s St. Peter’s basilica. We met 2 Indonesian girls, and returned wet to the hostel after a long walk through hard rain. We visited many famous places such as the Colosseum, Rome’s Pantheon (well, we didn’t go inside since it was closed), Paris’ Pantheon, the Eiffel tower on new year’s day, Sacre Couer, and Louvre. We also attended a mass in Notre Dame Paris.

After being freed from the thesis, I joined the Indonesian student community organisation for a trip to Rurhsee in the Eifel National Park near Aachen. I really enjoyed the fresh forest air during that almost-spring season. We had our dinner at Chicken Pon, and continued with the evening Easter mass with some guys who celebrated the Easter.

In late June 2010, I visited Strasbourg for a day trip with an EuMI classmate. We did several projects together during our stay both in Bonn and Trento, and he recently landed a good job as an IT architect in a subsidiary of one of the largest telecom operators in the world. Congratulations to him!


In July 2010, I went to a horse race show with my flatmate. Aachen is also famous for its horse race which has been taken place every year since 1924 (?). In the evening we travelled to Köln for a firework event called Kölner Lichter. I didn’t waste the chance for learning the basic of photography with my new DSLR camera during that day. The fireworks were awesome.

My junior in the Media Informatics programme (an Indonesian) invited me for a lunch with his friend who studies in Korea (also an Indonesian). We chose Chicken Pon and ordered a fair-sized plate of chicken, french fries, and salad. The other week, in early August, I went to the Drieländereck (the border point between Germany, the Netherlands, and Belgium) with this guy coming from Korea. A week later, we cooked together for a lunch and continued with a nice Indonesian dinner at Indonesia’s 65th independence day celebration in Aachen. I and some friends went to Köln to watch Inception as well in August, which, in my opinion, is a must see movie.


In late August 2010, a former classmate at the Gadjah Mada University visited Aachen, and we went downtown for a walk. Surprisingly, he brought with him a DSLR camera, so we took several pictures together. A week later, one of my EuMI juniors (an Indonesian) invited me for a farewell dinner. The food was nice. I wish him a happy stay in Trento 🙂

Those are the events taking place during the last 1 year with a relatively low level of granularity that I can trace back. Hopefully I can write logs more often in the future 🙂

Psalm 23

Switching to the religious part of me 😀 Several months ago I saw this nice clip of Psalm 23 on Youtube and I thought it would be nice to post it in my weblog. Psalm 23 has been one of my favourite passages from the Bible for a long time and this clip did pretty fine in wrapping the passage in panoramic scenes with a beautiful song. I like the last verse: “for Your endless mercy follows me, Your goodness will lead me home….”.
