Comments
from the
Editor
==========================================================
Developers can be power-greedy monsters.
Although I was going to use a more adult word than “monsters,” having
recently watched Sesame Street, I decided that the word monster works too. For
those who don’t live in a country that shows Sesame Street, it is a kid’s
educational show, and I have two twin two year olds, so I get to see lots of
Sesame Street. It includes a number of friendly monsters. Once such monster is
Cookie Monster. He often is seen trying to respect cookies and not eat them. In
the end, he has to completely devour them in full effort.
I’ve been working on an article and presentation regarding processor speed
and dual cores. I can’t quote the source, but in something I recently
read, the writer touched on multicore processors. More specifically, he stated
that application developers might use four to eight cores before the cost of
parallelism outweighs the benefits in most applications. If you add the
operating systems and other processes to this, a system would never really need
a 100-core processor.
When I initially thought about a 100-core processor, my thought was similar
in that the average developer would never need that much parallel processing in
a system based on today’s applications. Most people can’t even program for
single threaded applications, so the complexity of designing for large numbers
of cores is unimaginable.
A fraction of a quantum second later, I couldn’t help but think that it was
roughly two decades ago when it was stated that a developer would never need to
use 640 KB of memory. Today, 640 KB is laughable. Most of us throw away memory
sticks with 50 times more memory than that. I have 128 MB memory cards that I’ve
removed from my computers because the cards just don’t have enough
memory.
If you apply the lessons learned in using memory to that of getting power out
of processor cores, it raises an interesting question — just how many cores
will you be exploiting a decade from now? It would be interesting to see the
betting odds on this one!
As developers, I’m guessing as our machines get more cores, we will learn to
devour them in a similar manner as what Cookie Monster does with cookies.
Until next week,
Brad!

==> Windows Vista
– Integrate Ink into Your Application with Windows
Vista
By Nick Wienholt
Windows Vista brings
tablet-style development to the mainstream by incorporating ink functionality
directly into the core operating system. The greater availability of operating
system support for ink is complemented by new Vista drivers from digitizer OEMs
that provide the same functionality as a full TabletPC device, greatly
increasing the potential client-base for ink enabled applications. This article
will look at how an existing application can work with new forms of input
without a major re-design.
