  • SIX fintech hackathon

    I learned of hackathons before. It sounded interesting, but either they were too far away, the topic was not interesting enough, or the date was already booked. This time was different. The topic is really what made it interesting enough. FinTech is about new technology in finance. I’m sure there was innovation in the financial […]

  • Super secure BitCoin storage

    I wrote about multisig with different hardware wallets something more than a year ago. Back then It was awfully complicated and I didn’t really get it working. A lot of progress has been made since then. The functionality was added to electrum last summer for trezor. I couldn’t test it however because my two trezor […]

  • keepkey premium bitcoin hardware wallet

    I’m always interested when a new hardware wallet is announced. Naturally also for the keepkey. In contrast to most competitors, they didn’t take pre-orders. Instead they began to accept orders only when the product was finished and they were ready to ship. When they announced that the devices were finished and could be ordered, I […]

  • case bitcoin hardware wallet

    Part of the reason why I pre-ordered a case hardware wallet, was probably that there is no good wallet software on ubuntu phone. But the case is way more secure than a software wallet on a phone. Roughly the same size of the smallest feature phone you can buy, it contains an eInk display, a […]

  • ScroogeCoin

    After a long pause, I just started attending a MOOC again. It’s on Coursera, from Princeton and it’s about BitCoin. In one of the first lectures the teacher goes through some simple hypothetical digital coin concepts. I don’t know if the lectures are publicly available piecewise, but as a whole they are at youtube. Jump […]

  • When VISA doesn’t work

    I used to order stuff from dealextreme on a regular basis over the last few years. Like many other customers I asked them to accept BitCoin payments. But that didn’t happen so far. So we are left with the payment options from the last century for the time being. It used to work acceptably so […]

  • connecting home securely

    It has been probably close to a decade that I run a small server at home. At first it was only because I could not find a web hosting company that would serve my fcgi libwt apps at an affordable price. Then I added this blog to it. In the meantime I added a lot […]

  • libreboot and trisquel

    Last month I saw somebody on the fsfe mailing list talk about an OpenMoko phone. As I had one of those collecting dust in the drawer, I asked if anybody was interested. Promptly I got an offer to exchange it for a Lenovo X60 notebook with libreboot. I didn’t need another notebook, but libreboot seemed […]

  • xapo debit card backed by BitCoin

    It will take a while until we can pay with BitCoin at most merchants. For the time being xapo introduced a visa debit card that credits your expenses directly from your BitCoin online wallet at xapo. Since it runs over the visa network, and since there are currency conversions involved, it can’t be as cheap […]

  • prevent or react

    Beginning of this year, there was a very tragic event prominently present in all newspapers across Switzerland. The whole thing was so tragic, that I won’t add a link here. But there is one aspect, that kept me thinking for the last two weeks. Today’s blog post by Bruce Schneier triggered me to write about […]
