Yesterday, I managed to practice Aikido in Hamburg for the first time in almost twelve years. The dojo at Charlottenstraße was beautiful with windows to the outside and plenty of light. The training was interesting and very enjoyable. I even managed to practice with a few folks from university times. Next week, it's back to the US and Aikido practice in Mountain View.

With large and sinewy hands;

And looks the whole world in the face,
For he owes not any man.
We recently published an article on web-based malware in ACM's Queue Magazine. It provides a short overview of some of the challenges with detecting malicious web sites such as social engineering and examples of techniques for compromising web sites, e.g. htaccess redirection on Apache, etc. This is the article on which my recent ISSNet talk was based.
