Replace installer source path in registry

Usage:
Script runs locally on computer to replace installer source paths for installed software in the registry. Most likely usable if you migrate your DFS or file server when the path to the package changes.

Script does both current user and root hive.

Destroying the internet

Very interesting article on how to destroy the internet from gizmodo:

“Remember when Anonymous threatened to destroy the entire internet? We laughed, and ultimately their words were just hacker hubris. But it got us thinking—could someone actually destroy the Internet?

We did some digging, and guess what: With enough effort, the entire thing can be shattered. Physically. Completely. Here’s how to kill the net.”

IOmeter

When setting up Hyper-V hosts or clusters and using for example iSCSI it’s nice to know how the performance measures up. Or if you’re considering a new SAN.

How do you measure disk performance? With IOmeter of course!

ZeroN – Another touch interface. Or a levitating ball…

Quote: “There is something fundamental behind motivations to liberate physical matter from gravity and enable control. The motivation has existed as a shared dream amongst humans for millennia. It is an idea found in mythologies, desired by alchemists, and visualized in science fiction movies,” Lee tells Co.Design. “I have aspired to create a space where we can experience a glimpse of this future. A space where materials are free from gravitational constraints and controllable through computing technologies.”
