How you are tracked on this weblog
Ideally you should be visiting this page, and only you, the Mulle kybernetiK servers and all routers inbetween should know about this.
This is not true.
First of all, this weblog is tracked by a local Piwik. I use it because the webserver log contains very little useful information, due to bots and attacks. I use these statistics to figure out, which articles are popular and try to either embellish those or keep them updated. I think this is OK, because the tracking is just on this site, and the data isn't shared with anyone. You can opt out using the "do not track" setting.
The worst offender is the "Twitter" byline. I don't think Twitter is in the tracking business yet, but it could be. Assume you are tracked by Twitter.
mulle-kybernetik. So you shouldn't be tracked by those buttons.
The page also used the Hacker News Button for a short time on 18. Nov. 2015. That buttons back-end claimed to be hosted on Heroku, which I thought to be safe. Indeed though it is hosted on Appspot.com. Which is owned by Google. Mega-fail.
