According to my flight log book, it was the first of April 2002 when I had my first flight on a paraglider as pilot in control. Prior to that I did a tandem flight as the passenger and a few days at the training hill. Of course it all started much earlier. I wanted to… Continue reading Two decades of paragliding

Rest in peace Seppel & Hoppel
Yesterday I had to bury the beloved pet bunnies of our kids. But let’s start from the beginning. While I had plenty of pets in my childhood, my wive was less lucky in that regard. So she was especially eager to enable that possibility for our kids. Before they went to school, we bought a… Continue reading Rest in peace Seppel & Hoppel
Creating proof of reserves for an Electrum wallet
In my last post I promised to write about how you can produce a “proof of reserves” for your own wallet including hardware wallets. So, here we go. First you need an electrum multisig wallet that involves at least one hardware wallet. I won’t go into the details of how to construct this. Recently I… Continue reading Creating proof of reserves for an Electrum wallet
Proof of Reserves
As part of my work at SEBA Bank, I recently implemented a “Proof of Reserves” feature for our cold storage. The idea behind “Proof of Reserves” is that custodial businesses holding cryptocurrency should create attestations as to their reserves. Essentially proofing that they indeed hold, and have control over the coins that customers deposited. We… Continue reading Proof of Reserves
Blaming the healthy
More and more often I hear claims that the unvaccinated occupy beds in hospitals and shall somehow be solely responsible for spreading the virus. In reality 3% of hospital beds are currently occupied by Covid patients, and about half of them are fully vaccinated. 22% of beds in the supposedly overcrowded hospitals are empty. In… Continue reading Blaming the healthy

For our adventure in South America, we wrote our diary on a manually edited html page. On my personal blog, I still write… Continue reading A decade of blogging
Bye bye Jaguar
In my former Job, I visited customers from time to time. One day in 2001 on a parking lot across the street of a customer, I saw a gorgeous Jaguar XJ. It was from the second series, painted in British racing green and had a vinyl roof. It didn’t have a price tag, and I… Continue reading Bye bye Jaguar
Road trip to Norway with the Tesla
Our last road trip was a while back. After we returned from South America, we planned that our next big trip with the Büssli would be to Scandinavia. But we figured that family holidays with small kids are better stationary at one camp ground. Now that the kids are old enough, we didn’t trust the… Continue reading Road trip to Norway with the Tesla
Driving the Tesla
It is now almost three months and 7’000 kilometers. So I thought, I write a small review for my Tesla S85. Silence The immediate most notable difference when driving an electric car is the absence of the engine noise. People who drive big engine gasoline cars often assure how essential this is to their driving… Continue reading Driving the Tesla
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
