Port redirection under Windows
When you want to forward a port, there are several possibilities from iptables to SSH. However I needed a low-latency link with no encryption or compression (because the protocol running over it was encrypted and double-encryption just slows things down without any substantial benefit in this case). My first idea was to chain two Netcat…

You affect all of us
I finally decided to sit down and write the tutorial about configuring Windows XP in a secure fashion, based on my experiences in the last four years or so. And I emphasize again: these methods worked well for me on several computers and even in "though" scenarios like writing and debugging software. And then I…

Setting the CPU speed visually in Ubuntu
This is a nice little tip from a friend on how to make the your CPU frequency indicator actually work. Some things I discovered in the process: The sticky bit, which, if I understand correctly is an other way for privilege elevation under *NIX (the other two I know of are sudo and su). This…

Internet Explorer + Frames = Headache
So lets say you have the following HTML snippet: <html> <frameset rows="20,*" border="0" frameborder="no"> <frame name="menu" src="menu_frame.html" scrolling="no" noresize="1"> <frame name="work_frame" src=""> </frameset> </html> First of all you would say: but frames are so 1998! And you would be right. Frames are outmoded, deprecated and a usability nightmare (because you can’t bookmark the exact state…

Small Qemu tips
It’s official: Ubuntu has the best documentation out there. There is almost no problem for it you can’t fix by typing "Ubuntu [description of the problem]" or "Ubuntu [error message]" in your favorite search engine. For example, here you can find a very exhaustive documentation on installing Qemu and Kqemu (the Kqemu part is the…

Windows XP High-Security Configuration
Update: I found out that SRP has some rather nasty limitations (including the ability to circumvent it even as a limited user) which makes much less effective than I initially thought. I still thing it is very useful, but please read the linked article and make your own judgement call. As I mentioned in a…
