"Three things are important to realize about those images [showing results of volumetric rendering]: First, the hardware used to render them was built to render polygons, not MRI data. Second, if you've got an X-Box in your living room, you already own the requisite silicon. Finally, those images render in realtime, somewhere between 10 and 30FPS."

"Several doppelgangers may [..] be computed within a single multicollision-friendly block. As such, the particular selection of doppelganger sets within a file can itself be made to represent data. It's relatively straightforward to embed a 128 bit signature inside an arbitrary file, in such a way that no matter the value of the signature, a constant MD5 hash is maintained. This is curiously steganographic."

[..] incoming attacks to firewalls are also new. DNS trusts the hierarchy to tell it the next hop to its target name; since I can acquire second level domains in the hierarchy for minimal cost, it's trivial for me to insert arbitrary destinations along the DNS route path. In technical terms, whenever a recursing resolver comes to my name server to resolve a name, rather than providing an answer, I can redirect that request to another, supposedly authoritative server. That server can be at any address -- even one I cannot IP route to -- but if the resolver communicating with me can route to that address (say 10.0.1.11) my communication will reach that host. If there's an SSH over DNS daemon running on 10.0.1.11, I've now achieved incoming connectivity to the network of my choice, completely bypassing firewalls and a trojan's need to poll.
