A blog about personal projects and experiences

  • Choose your bleeding edge

    Are early adopters usually interested in only one new technology, or generally forward looking and open to innovation? I encountered multiple startups that seem to assume the former. As a company you want to make your product available for a large number of potential users. But who are your potential users? Sometimes you have to […]

  • Quality

    Quality is important During the apprenticeship at Victorinox we were indoctrinated with “quality above all else”. The teacher told us that also in our private lives we would be better off buying quality products even if they are considerably more expensive than throwaway products. Part of it stuck with me ever since. But I relaxed […]

  • Charging electric vehicles with Bitcoin

    In my last post I ranted about the current payment methods for charging E.V.s. The electricity for a full charge of an electric car costs something in the range of $2 to $20. But most of the time, we only need a partial charge. Credit cards impose enormous fees on low value transactions, and require […]

  • Charging electric vehicles

    First experience In a month of driving the Tesla, I collected some experiences but I feel I’m still a newbie. Charging is obviously very different from fueling a car. I gathered some information before buying the car, but it turned out I still had some misconceptions. The first thing I realized on the day after […]

  • Buying a Tesla with Bitcoin

    The first car that I bought at age twenty was dirt cheap, and didn’t last for more than two years. Then followed some Rover cars that were better, but also didn’t last very long. I was always the last one to own a car before it was no longer economic to fix it. After a […]

  • Hackthevalley Hackathon 2017 Baar

    Motivation After the good experience last year at the six fintech hackathon, I was trilled to go to hack the valley which is even closer geographically and whose subject is even closer to Bitcoin. My goal was to gain experience with ethereum. So far I only completed the tutorials. I found the technology very interesting, […]

  • Resetting the Logitech K810 bluetooth keyboard

    The Logitech K810 has been my favorite keyboard for many years. I have one at home and one in the office. It allows to easily switch between 3 different devices. It has the same size and layout as most notebooks, is stylish, and a blast to type. But one day about a year ago something […]

  • Meeting C++ 2016

    This is my first time at Meeting C++ in Berlin. I came here with my boss Andi. To profit more, we split up during the talks. Afterwards we shared what we learned. I will complete this post later, and add links to the presentations and videos as they become available. I attended the following talks: […]

  • Electrum 2.7 with better multisig hardware wallet support and Ledger Nano S

    Electrum has been my favorite Bitoin wallet software for a very long time. The reason I had a look at it initially was because there was a debian package. Only when Trezor hardware wallet support was added and was not yet released, I downloaded the sources. It is written in Python. I work with python […]

  • My new notebook

    Last week I finally received my new notebook. It was a long journey, but it was worth it. If you didn’t follow my blog, you can read about it here, here and here. Delivery It was delivered in two pieces. The first box contained the notebook, and was delivered normally. The second box contained the […]
