It's actually pretty different -- square is a simpler, passive device that essentially uses the mic and a tape head (remember those!) to read out the magnetic stripe on the card. This is actually much more sophisticated, since it harvests enough power from the audio signal to power simple sensors and a microcontroller, as well as giving you two-way communication. Also, it's not iphone-specific -- there are billions of cheap devices that you can now target with the same hardware; from this point of view the advantages are similar to the square.
There are actually several implementations of IPv6 for very low power, embedded devices. Arch Rock (www.archrock.com) has developed a commercial implementation. At Berkeley, we've developed open-source hardware (http://www.cs.berkeley.edu/~prabal/projects/epic/) and software (ttp://smote.cs.berkeley.edu:8000/tracenv/wiki/b6loWPAN) for low power IPv6 networking. Both the Arch Rock and Berkeley stacks support robust multi-hop IPv6 routing to support a large number of devices.

ASLR, which is used to randomly arrange the positions of key data areas to block hackers from predicting target addresses, is meant to make Windows Vista more resilient to virus and worm attacks." From the article: "Because most CPUs that ship today support DEP/NX, Howard explained that Vista users on older hardware can use the control panel to manually verify that PCs have DEP enabled. With full support from OEMs, Microsoft is effectively using ASLR to create software diversity within a single operating system, a move that is widely seen as Redmond's attempt to address the monoculture risk. The memory-space randomization technique will block the majority of buffer overflow tricks used in about two-thirds of all worm and virus attacks."
An anonymous reader writes "Defense Advanced Research Projects Agency (DARPA) has launched the ultimate speech translation engine project that would be capable of real-time interpretation of television and radio programs as well as printed or online textual information in order to be summarized, abstracted, and presented to human analysts emphasizing points of particular interest." If combined with the tower of babel project we discussed earlier, it could only lead to awesomeness.

The company, Steorn, says its discovery is based on the interaction of magnetic fields and allows the production of clean, free and constant energy — a concept that challenges one of the basic rules of physics." I can't wait until I can use this free energy to power my flying car and heat my aquarium of mermaids.
