| Wireless Registers Broadcast Credit Cards | | | Best Buy suspended the use of wireless registers
when hackers were able to grab credit numbers from
the parking lot. Best Buy had implemented a wireless
802.11b Point of Sale (POS) system without encryption
or security safeguards. The company responded quickly
to the discovery and pulled the plug on the new
systems May 1. Similar systems are used by Home
Depot and WalMart. Home Depot uses wireless for price
scans only (no credit card numbers). WalMart

| Melissa Creator Sentenced to Jail | | | David L. Smith, creator of Melissa, was sentenced to
Federal prison for 20 months. The sentence was less
than 5 years maximum because he had helped
authorities find other virus creators. Melissa was the
1999 Word Macro Worm that nearly shut down
business. Damage estimates were between 100 and
300 million dollars. Smith created Melissa in an
Aberdeen apartment using a stolen AOL screen name
and password to send it.

| Flexible LCD screen will Revolutionize Computers | | | A flexible LCD screen, developed by Royal Philips
Electronics, can be painted onto any type of
surface -- walls, plastic, or clothing. Called photo-
enforced stratification it involves painting a liquid
crystal and polymer mixture onto a surface, then
exposing to UV radiation twice. Radiation forces the
mixture to separate into a honeycomb of tiny individual
cell covered by flexible, see-through polymer. The
display is controlled by conductors on the bottom
surface.

| Look to the Future of Networking | | | This generation Internet links people. The next
generation Internet will link objects. Objects will be
embedded with Radio Frequency Identification Tags
(RFID) which are projected to cost 5 cents. Initial uses
will be inventory control. Future applications will
network the objects to perform useful functions. For
example, TV dinners might give cooking instructions to
the microwave. Proctor & Gamble have joined the
Smart Tag movement.

| Is the AOL model obsolete? | | |
AOL
taught a generation of Americans about the Internet. It provided
a cloistered, private network for chat and e-mail exchange,
with a portal to the Internet. Now the Internet is the focus
and AOL is primarily an ISP. With cable and DSL broadband
making headway, AOL may not be the preferred Internet entry
point. It will have to survive as a large site with content
and community. Can it make the transition?
