The Rise and Rise of BitCoin
As part of the Zürich Film Festival last week, they presented “The Rise and Rise of Bitcoin“. I couldn’t make it to one of the screenings where the director and the main actor were present. The room was fully booked, which I noticed with delight. I didn’t learn too much from the film on the […]

Presentations with code that actually works
I don’t do presentations that often these days. And if I do, more often than not, they contain some form of source code. With most things you write, you refine it over and over. This is especially true with stuff that you present. Applied to code snippets, that can mean you test it initially, but […]

The phone book of the internet age
When I was a kid, the main means of communication with remote friends was using telephones. If I didn’t know the phone number of their parents, I looked them up in the phone book. The phone books also contained the postal address. So if I wanted to send a letter or a packet, I could […]

Trezor BitCoin HardwareWallet
Today I received my Trezor BitCoin HardwareWallet. When I ordered it in June 2013, the expected delivery Date was October. But as it happens all that often with BitCoin related hardware, the dates get pushed back. They offered a device with plastic case for XBT 1 and one with an alloy case for XBT 3. […]

This in turn means lower taxes and insurance, but comes with the requirement to not drive more than 3’000km per year. Also the rate of technical examinations changes from 2 to 6 […]

key signing
I have been using gnupg for a couple of years for digitally signing emails and debian packages and occasionally for encrypting files as well for ssh authentication. I wanted to participate in the web of trust for a while. But so far, all key-signing-parties in my region were on dates, that I couldn’t attend. Then […]

Generating flight vouchers with LaTex
Learning LaTex was on my todo list for many years. Like most people of my generation, I learned wysiwyg text programs in school, and used them for a long time for most stuff that ended up on paper. Actually, to be exact, the first text processing program I learned in school didn’t fall into the […]

sweet dreams
For my last army service, I was ordered to Eschenbach SG near Rapperswil to help in an arsenal. It’s actually a long story, how it came to that. Compared to a regular service, it was very much relaxed. I could go home every night, which is quite nice, especially if you have a young family. […]

celebrating 2’000 flights
Last week, I didn’t even realize that I completed my two thousand’th flight. Only when I updated my flight log book, I found out. I knew that I’m close, but that day I did lots of short speed flights, and one of them was the one. For the first one thousand flights I needed only […]
