In theory if the world were filled we universally good people, “bitly” and “TinyURL.com“, which given long URLs provide short ones, are a great idea. However whenever I get one I find that I’m frankly terrified to click on them. Why?

Forgetting that there is a fairly regular stream of issues with the authorities, companies like GoDaddy issue certificates for all of $12 with nearly . . . → Read More: SSL certs – probably not worth the bits they’re printed on… If you get something like this in your Cisco’s IOS firewall log: Mar 12 15:05:33 192.168.1.1 3129: 003121: *Mar 12 15:03:03.195 EST: %FW-4-TCP_OoO_SEG: Dropping TCP Segment: seq:525214740 1415 bytes is out-of-order; expected seq:525170856.

That a deadly virus would escape from the military possibly causing zombies: http://www.cnn.com/2010/TECH/web/11/17/stuxnet.virus He was just wrong that humans would be the target. Well, researchers have devised a way around most modern anti-virus software. Yet another example of, “With friends like these, who needs enemies.” Again, I know “security by obscurity” is false security, but it’s not like the bad guys need as much help as they’re getting! Completely different from Cisco IOS, so hard to remember: Log into the PIX/FWSM and go to “enable” mode. Do a “who”:
