Understanding the radioactivity at Fukushima

This is the best presentation on the dangers of the Fukushima nuclear  plant disaster I have seen.  The presentation comes from Physics professor Ben Monreal of UCSB, which happens to be my alma mater.  Bone up on your periodic tables.

Conclusions
• The worst general-public effects of Chernobyl were
stress/fear; HUGE education/communication failure
• You have the information: count the millisieverts and
decide how to respond
• My feeling: the worst-case radiation hazards from
Fukushima are mitigatable and local
• (early evacuation + controls on 131I in food)
• My feeling: the global radiation hazard is nil.
• The best way to reduce worldwide low-level radiation
releases is ... stop burning coal
• Save your energy for those affected by the tsunami and
“50 plant workers” at Fukushima

Computer security

Bookmark these two websites to determine whether a web page or program poses a security threat.

For web pages: http://wepawet.cs.ucsb.edu/
For programs: http://anubis.iseclab.org/

These sites will help determine whether the particular page or program one enters displays malicious behavior.

Here's an article on the researchers at the Computer Security Group at UCSB, my alma mater.
