H. Peter Anvin announced on the linux-raid mailing list this morning that he has finally had some success in his attempt to implement software RAID-6 on Linux.
RAID-6, like RAID-5, is a parity RAID, but instead of using a single disk for parity informaiton, it uses two disks (two-dimensional parity). This results in the ability to survive two disk failures without a replacement or rebuild.
His code is still extremely experimental, but you can download and help test if you so desire:

Where do computer worms go to die? Recently I got curious what happens to the old worms that, by all counts, deserve to die a fast and painful death. So, I tapped into my security event storage, collected from honeypots and various other Internet-exposed sensors over the last couple of years. Here is what I came up with (see the link to picture and some rolling summary counts for ports and Snort NIDS alerts). The weirdest thing discovered was that even “bad old” CodeRed (circa 2001) is not going away.

The interesting and even peculiar part of this article is: if cyberterrorism is indeed as dangerous and real as those folks seem to claim, why should the defenses against it be voluntary and unregulated. To me, it sounds a bit controversial. Any ideas?
