| Macs and PCs on the Same Network | | | File and print sharing on a network that contains both
Macs and PCs can be a challenge. Fortunately there
are some easy solutions.
- If you need to attach a Windows PC to a network of Macs, install Miramar
System's PC MacLAN
($189) on the PC.
- If you need to attach a Mac to a network of Windows PCs, install Thursby
Software System's DAVE ($149)
on the Mac.
- Mac OS X can share files and printers natively with Windows
using Samba,
an open source technology that supports the Server Message
Block (SMB) protocol.
- If you want a low cost solution for file sharing, install
a free FTP server on either the Mac or PC and an FTP client
on the other.
- If you want a free solution for print sharing, use a
network printer. Configure both and Mac and PC to
print to the printer's IP address.
Please note that simply being able to share a file
does not mean that it can be opened by an
application.

| Security Hole in Mac OS X | | | A malicious DHCP exploit can give root access to Mac
OS X after reboot. DHCP (Dynamic Host Configuration
Protocol) is used for automatic network address
assignment. This vulnerability affects both Mac OS X
10.2 (Jaguar) and Mac OS X 10.3 (Panther). It is
particularly dangerous when the network has wireless
access. The exploit
takes advantage of the fact that a DHCP server is
listed as trusted by directory services (LDAP) after
reboot allowing root access. The exploit was
discovered by William Carrel. Apple currently has no
patch for the hole, but configuration changes can
provide protection (e.g. turning off DHCP and LDAP). A
full security advisory is available from carrel.org.

| RFID Tags and Privacy Concerns | | |
Radio
Frequency Identification (RFID) tags are everywhere. The most
common are the EZ Pass cards to automatically pay tolls. Retail
security and inventory control are also major application
areas.
RFID records were used to track US Attorney
Jonathan Luna's car the night he was killed. They
were used by NYC officials to prove fraudulent overtime
claims by 30 detectives. The records have been used in
child custody battles to establish work hours of
parent.
Stores have used RFID to track razor blades and
suits. Soon everything you wear will be tracked right
down to your underwear. Privacy advocates are
worried.

| What Would Marilyn Monroe Look Like Now? | | |
Forensic
art includes composite art, image modification, age progression,
post-mortem reconstruction and demonstrative evidence. Age
progression studies are probably the most interesting.
Stephen Mancusi has used age progression to predict what
Marilyn Monroe would look like today and what Michael Jackson would look like without plastic
surgery.

| US Voter Registration Data For Sale | | | Voter registration usually requires name, address, birth
date, phone number, and party affiliation. It may also
include race, driver's license, Social Security number,
and mother's maiden name. Most voters provide this
information under the belief that the data will be
secure.
Unfortunately state officials sell the information to
political parties and candidates, as well as, data
collectors. The California Voter Foundation found that
22 states do not put any restrictions on the release of
data. This is clearly a privacy violation.
Aristotle International, based
in Washington DC, has compiled these lists. Their database
includes 157 million names. They will sell to just about
anyone. The price varies from $25 to $80 per 1000 names.
Make an online list purchase by going to Aristotle's Voterlistsonline.
