Apple Security Update for OS X

June 3, 2011

Apple has released a new Security Update, 2011-03, for Mac OS X 10.6.  This update provides new definitions for the File Quarantine function, to cover the recently active MacDefender  malware; it also sets up an automatic daily update of the definitions.  Further information is in the update description; the update itself can be installed via the built-in Software Update function, or downloaded here.   A description of the File Quarantine function is available here.

I recommend installing this update as soon as you can.


National Academies Press Offers Free E-Books

June 3, 2011

The National Academies Press [NAP]  has announced that it is making all PDF editions of its books available for free download, effective yesterday, June 2.   The NAP is the publishing organization for the National Academy of Sciences, the National Academy of Engineering, the National Research Council, and the Institute of Medicine.  The list of available books currently includes  4,000+ titles, and will include most future titles.  Some older books are not covered because a PDF edition was never made; and there are a few specific publications on “Nutritional Requirements of Domestic Animals” that are not included.

The NAP has a FAQ page that covers the licensing and use of the PDF editions. The material is copyrighted, and not in the public domain; there are a few reasonable restrictions, aimed at ensuring that distributed copies are authentic.

This is another welcome step  toward making one of the hoped-for functions of the Internet materialize, by making a wide range of information generally available.
