This is going right over my head. I was trying to Google some of the terms so I could follow along as I was curious at how such at "attack" formulates in the mind of an "attacker"... Would you consider at the end of such post of posting a 'summary' for someone like me who is a writer and interested in the story but even with Google's enormous powers was unable to follow in any intimate way. This was a cool sight to stumble on and I was sure you could do a "for dummies" summary with only a paragraph or two. Plus, without endangering any subjects, you could also give general easy to understand scenarios where this could be used by "hackers" for nefarious ends. My curiosity is, again, perked! Thanks for posting. I'm going to add you as an RSS feed. Could you answer on here or email me if you would agree to do some kind of "for dummies" on the ends of posts? thanks dan Wow!

]]> Comment on Default behavior of Python’s cmp() by Chris Greene http://y_z.scripts.mit.edu/wp/2008/11/23/default-behavior-of-pythons-cmp/comment-page-1/#comment-5076 Chris Greene Thu, 13 Aug 2009 23:01:37 +0000 http://y_z.scripts.mit.edu/wp/?p=185#comment-5076 Hi! Thanks for this link. I suspect the reason for this sorting by class name is as follows: consider the list [100,"a",5] we would expect that when this array is sorted we'd get 5 before 100. However, if mapping id to each element gave us [1,2,3] this list would aready be in sorted order*. And you would be sorting on this ground presumably because all adjacent types are different. To ensure that the sensible cmp function is called you need all like types together. *(yes, numbers are automatically less than any other element, so in a real example, we'd need custom types to pull this off) Hi!

I just meant that the Trash specification leaves open a large number of decisions for the implementation, particularly with regard to top directory trashing on non-home mounts. The number of conditionals in the "Trash directories" section is large. Some of these are understandable, but others appear to be superfluous, such as the existence of both .Trash and .Trash-$uid.
