Software
is notoriously undependable. One reason is
that it is unpredictable. Unexpected conditions
like unusual input can trigger bugs that bring
a system down. A scheme that puts software
fuses between software modules aims to nip
problems in the bud. Full

Holograms
enable pocket projectors
Bulky video projectors are likely to go
the way of vacuum tube televisions and computers
thanks to several research efforts around the world.
One approach is to replace light bulbs and magnifying
lenses with lasers and holograms. The challenge
is reducing the computational load involved in producing
fast, high-quality holograms. An algorithm based
on how people perceive video could have what it
takes.
Memory
cards make connections
Applying to computers the romantic notion
that everyone has a soul mate can result in a simple
way to make connections. Sony researchers have turned
the company's flash memory card into a virtual wire
that allows people to connect two networked devices
just by plugging in a matched pair of cards.
Interface
blends screen and video
A computer interface that combines video
images and the computer desktop turns users into
ghosts in their own machines. Making the video and
desktop transparent allows both to be visible at
once, and fingertip tracking lets users control
the mouse by pointing. A two-user version puts a
new twist on videoconferencing.
