let’s encrypt
I never bought a commercial grade SSL certificate for my private website, but I used free ones before. Usually from startssl. While it worked, the process was cumbersome. And then when I wanted to renew, my browser showed a warning that their own certificate was out of order. When the letsencrypt initiative (supported by mozilla […]

an exact clock for a vintage car
Since I drive my vintage XJS not too often, I disconnect the battery. This is to prevent if from going flat before I want to use it the next time. Of course it would be better to install a special charger for classic cars. But there is no outlet in the underground car park. The […]

the infinity mirror
Lately while browsing through thinkgeek, I stumbled upon the infinite dungeon corridor. It looks cool, but they still have no affordable shipping options. That got me thinking that it should be possible to make an infinite mirror with the kids. It didn’t take long to find a recipe for how to go about it. Finding […]

Targeted advertising
It was about two months ago when I first noticed an advertisement on some random web page that contained an image of a vintage Jaguar XJS. It was not exactly the same model as I have, but very close. Judging form the bumpers and trims it also seems to be a HE (High Efficiency), as […]

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 […]

Verifying downloads
Last week I stumbled across a post from last year, where somebody described how it was impossible to download an important infrastructure program securely on Windows. My first reaction was of course to pity the poor souls that are still stuck with Windows. How easy is it to just type apt-get install and have all […]

How much luggage fits into a vintage grand tourer?
Our camper has an engine problem, so we had to look for alternatives for this years summer holiday. We looked at last minute offers, but bringing all our own food to Greece didn’t seem like such a good plan. The kids wanted to sleep in a tent anyway, so we went to Tenero in the […]

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 […]

ubuntu phone will be great, but it is not yet
The BQ Aquaris ubuntu phone that I waited for so eagerly was delivered today. Full of anticipation I unpacked it and switched it on. After playing with it for a while the excitement turned into dissatisfaction. I hate to say it, but on a phone the solid base and polished user experience is not enough, […]
