You have probably heard already of
Tor, a tool for
surfing the internet anonymously. It can also be used to evade
censorship, but less known is the fact that you can turn the tables
and monitor internet censorship in various parts of the world. Not
only that, you can use Tor to visit websites pretending you come from
almost any country.

Yesterday, Microsoft and Milan-based Sourcesense
announced
they collaborate to contribute code to Apache
POI, a Java library for manipulating
Microsoft Office files. This collaboration has two possible
consequences: either it will turn POI into the greatest patent laundry
of all time, or it will help Microsoft to launch a patent ambush on
the project. Feel free to decide which one is more likely.

libquantum 0.9.1 has been released. The new release adds
an interface for time-evolution of arbitrary Hamiltonians using a
fourth-order Runge-Kutta algorithm. The license has been changed to
GPLv3 and several bugs have been fixed. Further information can be
found on the libquantum
website.

As some of you may know, I wrote my diploma thesis on transport in
quantum thermodynamics. Related to this work, we now put up a
paper on arXiv, describing how
to incorporate the concepts of work and heat, which are well-known
from the classical world, into the quantum realm.
It turns out that if you do it properly, you get some remarkable
consequences, like a machine that both works and does not at the same
time. These strange things arise (hardly surprising) from
non-commuting observables in quantum mechanics.

Last Friday, a new law on computer crime came into effect in
Germany. The newly introduced Section 202c of the German penal code
created much
buzz around
the net since it prohibits the distribution of certain computer
programs assisting in committing data espionage.
Although I think the law is bad and creates an uncanny area of
uncertainty it is not the end of all security research done in
Germany. In fact, much of the current outcry is overblown and
counter-productive, as it contributes to spreading FUD about the
issue.

Okay, I promise I won't mention every article I write for
OS Reviews on my blog, but here is an exception. I just put up an
article about Nexuiz,
which is definitely the best first-person shooter I've ever
played. And of course it's free as in speech!

Most of you probably remember the delisting
trouble
SCO got into because they failed to timely file their 10-K back in
2005. The same story will show up again soon, but this time for
another reason: the stock price is too low to meet Nasdaq's
requirements. Read more

Accessing scientific papers online is great because it spares you the
way to the library. Unfortunately, most journals make their articles
available only to paying subscribers (contrary to Open
Access). So if you want
to read an article at home or while on a conference you have a
problem. This posting shows you how to access it anyway just by
clicking on the download link in a journal. Read more

From time to time a vulnerability is found in a virus scanner that
allows an attacker to disguise malicious content so that the scanner
won't detect it but the virus is still fully functional. Much rarer
are discoveries of new attack classes that are able to blindfold not
one but many virus scanners. Here is one. Read more

So I finally have a blog, too. At the moment there is not much to see
around here, but I'm sure that will change soon. Read more
