| 802.11a versus 802.11b Wireless Standards | | | One standard would be best, but we have two.
802.11a operates in the 5Ghz band and 802.11b
operates in the 2.4Ghz band. 802.11a has a 55Mbps
speed versus 11Mbps for 802.11b. 802.11b has better
coverage and range. Both have security problems.
802.11b has interference problems because it shares
the band with wireless phones and Bluetooth. 802.11b
is cheap and readily available. 802.11a will be widely
available within 6 months because of the low cost
Atheros chip set. To deploy now or to wait for dual
mode technology, that is the question!

| Personal Backup Strategies | | | Hard drive technology has made enormous strides.
Most computer systems now have drives larger than 10
GB. How can that much data be backed up
conveniently and cheaply? The options include CD-RW
(630MB), DVD-RAM (9GB for double sided), DVD-RW
(3GB single sided), Zip Drives (250MB, 100MB), Tape
(the old expensive standby), and a second hard drive
(my personal favorite).

| Readers for the Visually Impaired | | | Many times the visually impaired have trouble
navigating a complicated computer based reading
system. Wouldn't it be wonderful, if a simple device
could be created that would scan any written page,
perform optical character recognition (OCR), and then
read the file back to the user using voice synthesis.
There are now several stand alone systems on the
market that do just that. Readsmart is a leader in the
field. Check the Stratford website for more links to
such devices.

| Microsoft's anti-Unix Website fiasco | | | Microsoft and Unisys created We Have
the Way Out to show that Unix is a dead-end
maze. When it was discovered that the site was hosted
on FreeBSD servers, Microsoft moved it to
Windows 2000 servers. The site promptly crashed. A
parody site quickly sprang up We Have the
Way In, which tries to show that Windows is a
dead-end strategy. Isn't technology fun!
