There has been a lot of press this week about Cisco UCS passing the 10,000 customer mark, which is an outstanding achievement. But I have found none yet that explains why it is getting so much traction.

This last weekend I almost lost all the pictures. We have four kids, and have tons of pictures. I had set up the user accounts on our Mac on an external mirrored drive, connected by Firewire. This was mostly good, but this weekend all the applications just refused to connect because of some kind of weird permissions issue. I went through all sorts of stuff to get it working, but at the end of the … Read the rest

Viruses, trojans, malware, and other problems routinely crop up on Windows machines – they are a fact of life. I just refreshed my computer troubleshooting skills on a Windows 7 laptop that was unusable. It had been taken over by a fake computer security application that was demanding money to continue allow the PC to continue to work.
