  • Reproducible Builds – Telling of a Debugging Story

    I try to make PGPainless build reproducible. A few months ago I added some lines to the build script which were supposed to make the project reproducible by using static file modification dates, as well as a deterministic file order in the JAR archive. However, recently my JAR files started to contain mismatching bytes…

  • Europe Trip Journal – Entry 30: Thank You for Traveling with Deutsche Bahn

    It is time to go home. This morning I woke up at 9:20 and decided to get some breakfast. Afterwards I returned to my room and was greeted by my room mate H. who told me that the cleaning personnel wanted to do their job and that checkout was supposed to be done at 10:00. It was already 10:20, so I hurried and quickly collected all my belongings.

  • Europe Trip Journal – Entry 29: Prepare for Reentry

    Today I got up a bit earlier than yesterday, meaning I had to actually pay for breakfast again ;). Unfortunately the coffee was already running out, so I only got a single cup which had to do it. Milk was also empty, so no cereals this time. Well, there was yogurt as a worthy replacement.

  • Europe Trip Journal – Entry 28: The Above and the Beneath

    In retrospect I realize that during my trip I have made lots of photos of churches and cathedrals, even though I’m not a religious person. I believe that many problems of society are directly or indirectly caused by religious fanaticism, ideology and authoritarianism, hence I’m not a big fan. My philosophy is that if you need someone else – like a book – to tell you how to be a good human, you are not a good human. However, you cannot NOT be in impressed by the massive scales of cathedrals built hundreds of years ago. These architectural masterpieces stand testament to the fact that religion can also excel humanity, even though it may only be a side effect of exercising power.

  • Europe Trip Journal – Entry 27: Oh Champs-Élysées

    Yesterday I had some breakfast in my hostel and after that I took the metro to the Châtelet station which is close to the Seine. When I was in Paris near the start of my trip (which is almost 4 weeks ago at this point) I had walked down the riverside path of the Seine and therefore had missed some points of interest that lay behind the quay wall.

  • Europe Trip Journal – Entry 24 – 26: OpenPGP Email Summit

    After quickly refreshing, I took the bus to the other end of Geneva to the offices of Proton (formerly Protonmail). They hosted the 6. OpenPGP Email Summit which I was going to attend. When I got to the building, I had to call the office upstairs and one member of the Proton team came down to fetch me. On Thursday we only had an informal meeting of participants that already arrived. The real discussions would take place on Friday and Saturday, although when I entered the office room people already had discussions going.

  • Europe Trip Journal – Entry 23: A Hike and a Hat

    Wandering though a passage way, I came across a store that sold French hats. Since this was expected to be my last stay in France on this tour, it was now or never, so I entered the shop and ended up buying a hat. Surely, with this hat I would perfectly blend in with the local population. Later I learned that my hat was from Italy :P. I normally don’t enjoy buying clothing, and a hat is something I would have never really identified me with before. Still, for some reason this hat made me very happy as it perfectly captured and somehow embodied what I felt in this moment.

  • Europe Trip Journal – Entry 22: Drowsy and Annoyed

    Today was a rather slow day. I got up at 8:20 to get breakfast at the hostel. This time they had bread \o/. I was the only one eating there, everybody else (there was a group of elderly people staying at the place too) must have gotten theirs already. At some point C. came down to get her breakfast too. She however decided to eat in the garden.

  • Europe Trip Journal – Entry 21: Ferris Wheels and Train Tickets

    This morning I got up at 8:00 which is an hour earlier than during the rest of the trip – and lets not talk about my usual sleep schedule. The reason was that breakfast was served from 7:00 to 9:00 in the hostel. J. and me arrived at 8:15 or so and to my disappointment there was no bread left. As a replacement they served Zwieback onto which I applied a thick layer of jam. After the breakfast it was time to say farewell to J. as he had to catch his train.

  • Europe Trip Journal – Entry 19 – 20: Tranquility

    The sun was slowly starting to set and was sending its warm, friendly beams my way. Birds were singing and the tall grass was ticking my legs. A pleasant warm summer breeze was carrying the distant, muffled sounds of the city which was slowing down after the day. It was a summer evening in France. Suddenly all the exciting and all the wrong that was going on in the world faded into the background. For a short moment priorities shifted and the world seemed to center around me and my laundry. It was a perfectly peaceful moment of tranquility and I enjoyed it.
