Good Experience: Bit literacy: an overview. Obviously, bits have become more important to the average technology user since then. In fact, I find that the essay - although it predates those developments - is even more relevant in 2004. Thus I plan to write more about bit literacy this year. [Tomalak's Realm]

How do homing pigeons navigate? They follow roads. By Caroline Davies,
The Telegraph (UK).
Zoologists now believe the phrase "as the crow flies" no longer
means the shortest most direct route between two points. They say it is
likely that crows and other diurnal birds also choose AA- suggested routes,
even though it makes their journeys longer.
Some pigeons stick so rigidly to the roads that they even fly round
roundabouts before choosing the exit to lead them back to their lofts.
Animal behaviouralists at Oxford University are stunned by their findings,
which follow 10 years of research into homing pigeons. For the last 18
months they have used the latest global-positioning technology, allowing
them to track the ground the birds covered to within one to four metres.
It really has knocked our research team sideways to find that after a
decade-long international study, pigeons appear to ignore their inbuilt
directional instincts and follow the road system, said Prof Tim
Guilford, reader in animal behaviour at Oxford University's Department of
Zoology.
For long-distance navigation and for birds doing a journey for the first
time, they will use their inbuilt compasses and take sun and star
bearings.
But once homing pigeons have flown a journey more than once, they home
in on a habitual route home, much as we do when we are driving or walking
home from work.
In short, it looks like it is mentally easier for a bird to fly down a
road and then turn right. They are just making their journey as simple as
possible.

There are illustrations, too:

The music pirates' manifesto
By Annalee Newitz, San Francisco Bay Guardian.
With a groan, I peeled the transparent sticker off my
brand-new iPod. In the clean, cute font for which
Apple is known, it read, "Don't steal music." Even the
wrapping paper on my smooth little machine was full of
antipiracy propaganda. But the software wrappings
Apple places around the music the iPod plays are far
worse than propaganda: they enforce, with no subtlety
or charm, the licensing preferred by corporate
copyright holders.
Once upon a time, Apple's slogan "Rip. Mix. Burn."
meant "make as many copies as you want of your legally
purchased music." Now it means "make the limited
number of copies we deem appropriate." All that's
being ripped, mixed, and burned are fair-use laws . . .
