Many thanks to Otis Gospodnetic of Simpy for putting me in contact with Benjamin Reitzammer. Benjamin has graciously set up the GrabPERF measurement script on his server in Zurich.

The machines, hosted in my basement, are connected using Verizon FiOS, which has become increasingly flaky over the last couple of months. As well, the machines are 7 year old Pentium [...]

My side project, GrabPERF, is looking for a few good measurement locations.

Why doesn’t the right-click work in the message list in Outlook 2003?
Can you detect when a program is activated by an actual mouse event, [...]

Dave Sifry and his team have been very good to me. You know, bite the hand, etc.
But I got up from my afternoon siesta, and found this,

And when I finally did get a copy of the page…

Ouch.
Wonder what a Technorati Monster looks like….

It’s always funny when somewhat tech-savvy folks purposely make their bandwidth bills higher than they need to be.

Every day, the Digg search measurement times explode.

Maybe they need to look at that code again…
