XBOX 360 Dies Again

2007-08-26 21:57:00 by Eric Marvets in The Security Samurai

I contacted Microsoft, and they agreed to fix the console (only 6 months old), but that it would take 3 to 5 days to send me a box to ship it to them in, and then...

After reading Bruce Schneier s interview with TSA Administrator Kip Hawley I started thinking of all the explosives used in recent terrorist plots and how silly they were. As a kid, I loved going into the woods and playing with all sorts of dangerous stuff which of course included fireworks, gas cans, hair spray, propane tanks, etc. What I...

2007-08-02 08:19:00 by Eric Marvets in The Security Samurai

The number of valid comments pales in comparison to the number of spam messages so I'm just going to turn it off. I wish I had the time to add some sort of captcha function and will look at adding it in the future I...
