If you are an IT professional providing customers with Internet connectivity solutions you know that the internet is a scary place. Back in the dark ages (before 1993) when things started out everyone using the internet trusted each other. Unfortunately things changed drastically and trust is a thing of the past on the internet.
When you set up an internet connection for a customer you do everything you can to protect them, you set up a restrictive firewall, you have a proxy that enforces policy for web surfing as far as possible. You also use all possible means to block spam and viruses in e-mail before they reach the lusers that still believe Bill Gates will give them free Nokia cellphones.
After you did all the technical stuff, you tell everyone (you know it falls on deaf ears, but you have to try) that they must not visit those porn sites, that they must copy links in e-mail and paste them into their browser rather than simply clicking on them etc. So what happens when one of the lusers that actually listened goes to a legitimate website and still have his windows computer exploited? Or if they are lucky the lusers get a warning from their anti-virus software and the site gets blocked.

While browsing through hack a day yesterday I found this Nokia smartphone vulnerability.
If you go to the link you will notice that it was the Chaos Computer Club that published the vulnerability. I have written about them before and think they do great work to raise awareness about the risks in computers and other electronics. Some may think that they are irresponsible, but are the large companies that release equipment with these kinds of vulnerabilities not way more irresponsible?

Yesterday Andrew McGill posted the message below on the Gauteng Linux User Group mailing list. Because he is not blogging I’m doing it for him. What he is describing is one of the biggest frustrations people have with so called new and improved software. more....

Virtualizing a Supercomputer
bridges writes "The V3VEE project has announced the release of version 1.2 of the Palacios virtual machine monitor following the successful testing of Palacios on 4096 nodes of the Sandia Red Storm supercomputer, the 17th-fastest in the world. The added overhead of virtualization is often a show-stopper, but the researchers observed less than 5% overhead for two real, communication-intensive applications running in a virtual machine on Red Storm. Palacios 1.2 supports virtualization of both desktop x86 hardware and Cray XT supercomputers using either AMD SVM or Intel VT hardware virtualization extensions, and is an active open source OS research platform supporting projects at multiple institutions. Palacios is being jointly developed by researchers at Northwestern University, the University of New Mexico, and Sandia National Labs." The ACM's writeup has more details of the work at Sandia.

Anyone that runs a mail server very quickly learns how to fight spam if he wants to do his job properly. It is also one of the favourite pastimes of the clueless to think up stupid ways to fight spam. Today I saw a brilliant answer to one of these ideas on the postfix mail list. more....
Wordpress, the software I use for this blog is great and has a wonderful plugin system that allows people to add functionality that is not originally included in wordpress. Unfortunately many of the available plugins are not so wonderful and often do not work as expected (advertised). more....
