  • A strange kind of holiday

    It all started about two weeks ago when my wife discovered water on the kitchen floor that kept coming. The plumber who came immediately, found out that two parts of the waste pipe shifted out of each other, leaving a gap open. He told us that this must have happened two or three weeks earlier. […]

  • Fading out my credit card

    Once upon a time there was no internet. When you went to a restaurant, you had to pay in cash. If you had no cash with you, you might have been lucky if the owner knew you good enough to think you were credit worthy. But what if you were in another city? Then some […]

  • Back to Mac (nothing to do with Apples)

    After I stopped flying in competitions, I also slowly stopped flying competition gliders. So I went back to my old and proven sports class glider. I meant to replace it for a long time. But as my Gradient Aspen 1 is by now more than eleven years old, there really were no more excuses. So, […]

  • MultiSig with HardwareWallets

    2014 is touted as the year of multi-signature for BitCoin. It is being integrated into some wallets and services. But not quite the way I expected. Electrum has an implementation that assumes multiple hierarchical deterministic wallets distributed over different machines, that know the other’s master private keys. -> This should work well for corporate environments […]

  • Visiting the doctor after 20 years

    My wive usually rolls her eyes, when I tell her: “No, I don’t need that medicine. My immune system can cope with that, and needs to be trained.” or “No, I don’t need that painkiller as long as the headache is not overwhelming. My body reminds me that I should not shake my head too […]

  • electrum server on a cubox

    I don’t even remember if there were alternative wallets available when I started with BitCoin. I used the reference implementation exclusively for a long time. Now there is a wide variety to choose from. They fall in three main categories: full node, light client and web wallets. They are nicely listed and explained at bitcoin.org full node Every […]

  • Hello Kitty

    Since she was a kid, my wive dreamt of having a pet, preferably a cat. Our kids also said they would love to have a cat or a bunny or a turtle or… I grew up with animals. We had cats and dogs and sheep and goats and chicken and once even a pig. We […]

  • HW1 tiny BitCoin hardware wallet

    While the trezor is certainly a great device for securing BitCoins, I’m also interested in alternative hardware wallets. Even in my very first discussions about increasing the scurity of BitCoin we talked about SmartCard solutions. After all, that’s also how I secure my GPG keys. But a regular SmartCard alone only protects the keys. If […]

  • What could go wrong when ordering pizza?

    For some months now it was possible to order pizza for BitCoin in our area. I wanted to give it a try since it was announced. But only last Thursday, I proposed to my coworkers to order pizza. And that I would pay with BitCoin. It was meant as a demonstration how cool the virtual […]

  • Paracuda walk & fly

    In the Paracuda paragliding club, we distribute the organization of the events among the members. So I agreed to organize a “walk n fly” event in October. Usually pilots go up with a cablecar to go flying. This saves us from having to carry the equipment for too far. But for people that want to […]
