After a hiatus of over 10 years I’m back on ZDNet, writing mostly about security.

Some of my initial blogs there:

• Trust the PKI or it’s anarchy on the Internet
  

• BGP spoofing – why nothing on the internet is actually secure

• Xerox scanners alter numbers in scanned documents

• Cybersecurity incentive proposals from White House underwhelm

   

We’ve got a new Doctor (Who), Peter Capaldi. I believe the only thing I’ve seen him in was the 5 part Torchwood: Children of Earth, in which he played the heartless British Civil Servant John Frobisher. There was nothing extraordinary about his acting there, but the role called for a cold, businesslike bureaucrat, so it’s not really the best basis for judging him. Little of his work seems to have had an American audience.

I still prefer the Classic Dr. Who and I’ve been watching whatever episodes are available on Amazon Instant Video. I can’t find a poll widget that can do ranking, but please use the comments to rank the classic Doctors from 1 (best) to 7 (worst). Here they are chronologically:

William Hartnell
Patrick Troughton
Jon Pertwee
Tom Baker
Peter Davison
Colin Baker
Sylvester McCoy

and here is my ranking:

1. Tom Baker
2. Sylvester McCoy
3. Patrick Troughton
4. Jon Pertwee
5. William Hartnell
6. Peter Davison
7. Colin Baker

I’ve developed a real appreciation for McCoy.
