Nimda uses more ways to spread than the ones used by Code Red. Code Red used a buffer overflow, Nimda uses directory traversal to get the IIS.
Nimda does look for possible backdoors left by Code Red or other worm.
From CERT:
The "Code Red" worm is malicious self-propagating code that exploits Microsoft Internet Information Server (IIS)-enabled systems susceptible to the vulnerability described in CA-2001-13 Buffer Overflow In IIS Indexing Service DLL.
and:
The CERT/CC has received reports of new malicious code known as the "W32/Nimda worm" or the "Concept Virus (CV) v.5." This new worm appears to spread by multiple mechanisms:
from client to client via email
from client to client via open network shares
from web server to client via browsing of compromised web sites
from client to web server via active scanning for and exploitation of various Microsoft IIS 4.0 / 5.0 directory traversal vulnerabilities (VU#111677 and CA-2001-12)
from client to web server via scanning for the back doors left behind by the "Code Red II" (IN-2001-09), and "sadmind/IIS" (CA-2001-11) worms

Hello, the major manufacturers offer 10-year and even 25-year warranty for their panels.
In Brazil, because of the energy crisis (hey, if it's good for California...), the government has dropped almost all taxes for alternative energy.
Nevertheless, it still can take about 30 years for a solar system (!?) to pay for itself, because "wired" electricity costs US$ 0.075 per kW.h.
Now, don't forget that when a country deploys "solar farms", it's actually using other country's energy (unless the panels are locally manufactured). Making a solar panel requires a lot of energy. In a way, if I buy a panel manufactured in California, I'll have clean energy here at the expense of more pollution in the US:)
Anyone knows how long does it take for a panel to "pay" for this energy?

Not quite.

Since July IIS market share has been falling.
Check the
The share is flowing to Apache and Netscape servers.
