Powershell: Kill Idle Terminal Server/Remote Desktop Processes

We see a lot of these RDP sessions going idle with memory-hogging applications open, like IE/Chrome, ERP software, Adobe Reader, etc. When you have dozens of sessions, these small bits of RAM can really start to add up. And because the uses are needed 24/7, the sessions can’t be terminated. I thought it would be nice if there was a way to say “Hey, this IE process has been idle for an hour, lets just kill it.”

Adventures in Administration: USB Extension Cables over Cat5e Ethernet

While working as an admin you come across some unusual requests.

Did some quick googling and found this page, which has the solution. If that fixes your issue, let them know by dropping them a comment!

Realtek RTL8191SEvA Wireless in Fedora

We’re rolling out a bunch of Fedora-based thinclient-like devices at work that contain a RTL8191SEvA chipset. Unfortunately, this isn’t built into the kernel as of 2.6.38.8-32.fc15 (I think there are licensing issues at play), so it has to be compiled and inserted by hand.
