I just returned from #hack4climate. Even if it was just my third hackathon, I can state with certainty that this one was unlike any other. None of the 100 hackers from 33Â countries experienced anything remotely comparable before. The topic of the event was to develop solutions how blockchain technology can help fighting climate change.… Continue reading The mother of all hackathons

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… Continue reading Choose your bleeding edge
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… Continue reading Charging electric vehicles with Bitcoin
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… Continue reading Charging electric vehicles
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… Continue reading Buying a Tesla with Bitcoin

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… Continue reading Electrum 2.7 with better multisig hardware wallet support and Ledger Nano S
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… Continue reading My new notebook
Decentralized websites and more
“Cool idea, but to be of any use, it would need more functionality and more content” was my impression when I first looked into zeronet. Back then static web pages were all there was, and no UI support for any managing tasks. The next time I checked, probably more than half a year later, it… Continue reading Decentralized websites and more
Worst customer experience ever
The best notebook ever I blogged about my attempts to buy a decent notebook here before. But let’s recap quickly. In the fall of 2013 I bought a Dell XPS13 Developer edition. When Dell shortly thereafter announced that they now accept BitCoin, I had the feeling I missed out on that opportunity. Nevertheless, it was… Continue reading Worst customer experience ever
