Open Source Cloud

RackSpace and NASA have announced today the OpenStack Open Source Cloud Computing Software

The goal of OpenStack is to allow any organization to create and offer cloud computing capabilities using open source software running on standard hardware. OpenStack Compute is software for automatically creating and managing large groups of virtual private servers. OpenStack Storage is software for creating redundant, scalable object storage using clusters of commodity servers to store terabytes or even petabytes of data.

They only are in developer preview mode, but I searched the site and found no mention of security or compliance. Hopefully this will change by the first release in mid-October.

Microsoft Shell Exploit

The remote code execution warning was posted yesterday for Windows Shell on XP: Microsoft Security Advisory (2286198).

The vulnerability exists because Windows incorrectly parses shortcuts in such a way that malicious code may be executed when the user clicks the displayed icon of a specially crafted shortcut. This vulnerability is most likely to be exploited through removable drives. For systems that have AutoPlay disabled, customers would need to manually browse to the root folder of the removable disk in order for the vulnerability to be exploited. For Windows 7 systems, AutoPlay functionality for removable disks is automatically disabled.

Turn off AutoPlay
It was no good anyway
Except for exploits

Update: Sophos says disabling autoplay is not an answer

Sophos senior technology consultant Graham Cluley told ZDNet UK that the rootkit circumvents preventative measures such as disabling autorun and autoplay in Windows.

“This waltzes around autorun disable,” said Cluley. “Simply viewing the icon will run the malware.”

Convert your mower to electric

I am unable to think of a single good reason to have a gasoline-powered lawn mower. Perhaps someone can enlighten me.

In the meantime, I noticed an excellent tutorial on how to convert gasoline mowers to electric, and recharge them with solar.

Solar Mower

Compare the silent, clean and simple electric/solar model to even the smallest lawnmower gasoline engines that pollute 93 times as much as an automobile engine.

The NYT points out that 6 million gasoline mowers were shipped into California in one year. That is the equivalent of 600 million car engines pumping toxic fumes and noise into residential areas. Why?
