Kroger: A Case Study in Security Theater
Security Theater, simply put, is what you see when you go to the airport, or a court house, or perhaps even your local gas station. A well designed and functional security system should be seen, not used. I would, 100 times over, rather somebody who wants to do me harm, see my security cameras and…

I’ve Built a Computer
Here’s when it was more “in progress” Perhaps evident from this picture, that the 16K of RAM in the top right is still not connected.

Decoding USPS PO Box Combinations – Part 1
A few weeks ago I took a trip to a local antique mall here in Texas. It’s been a few years since I’ve been to one and last time was to find old school padlocks to pick. I found this USPS PO Box door (presumably box #60563) for sale for $20, along with several others.…
