Comments
from the
Editor
==========================================================
I watched Star Trek Enterprise last night. It was a two-part episode that
took place in an alternate reality where Earth was a more aggressive planet with
an Emperor. In this episode, the Enterprise crew finds a future Enterprise and
takes it. Within minutes, they are making repairs, firing weapons, and flying
it.
This past week, I also have come across several references to Charlie Stross’
comments on colonizing the Universe — and its impossibility. This story has
been picked up by Slashdot and many other sites, including Codeguru now that
I’ve mentioned it.
http://nl.internet.com/ct.html?rtr=on&s=1,39b6,1,lg7c,3o59,jorm,i5r0
What is interesting about these two different situations is that they don’t
clearly take into account that advances in technology happen that are often
beyond the comprehension of those in prior generations. For example, if you took
someone from the 1950s, put him or her in a kitchen today, and told him or her
to heat up a piece of pizza, what would happen?
They would likely look for matches so they could turn on the oven, wait for
it to heat up, and then wait while the pizza warms. Total time spent to heat the
pizza could be 20 or 30 minutes. The concept of using a microwave oven to heat
the pizza — without actually using any heat — would be….unimaginable. To do
the heating in a matter of a few seconds would also likely amaze the person.
They might have thought it to be impossible. The microwave would be in the realm
of magic.
So, when a crew takes over a ship that is 100 years ahead of their time, it
would be surprising to see them determine how to use it in a matter of minutes.
Most of the underlying paradigms they would be used to would likely have
changed. In the same manner, there are paradigms and technologies we can’t
necessarily predict today that could help us with space travel.
As people who use technology, the same paradigm shifts should be expected in
our industry as well. I’ve mentioned quantum computers in the past. I see
quantum computers falling in the same realm as these ‘magic wand’ paradigm
shifts. Changing underlying knowledge from an on/off or zero/one paradigm to a
“zero, one, and everything in between” paradigm isn’t going to be simple. I’m
sure that once the paradigm becomes the standard, it will be easy to follow.
More importantly, we are likely to look back and wonder how things were ever
done in a binary world!
Just as a five year old can grasp the concept of heating up food in a
microwave today, so too will new concepts in computing be easy to grasp once
they are here. In the meantime, let’s not write off the future because of our
lack of understanding today.
Until next week,
Brad!

==> Java – Annotations
– Inherited Annotations in Java
By
Mikhail Milonov
Despite the fact that the fully operational annotation
mechanism appeared in Java not so long ago, many developers have appreciated
this new possibility of Java API and use it in their programs. To solve this
problem, learn about a library of inherited annotations.
