Distributed systems require rethinking of hands-on interaction.When someone says that something is "remotely possible," most people
take it to mean that something might happen but isnt likely. I wonder
if application developers will soon find themselves hearing a different
and more positive meaning in that phrase, along the lines of "Yes, you can
make that happen anywhere, from anywhere."
My thoughts in this direction begin with Microsofts plans for a
more general and much better abstracted approach to hardware drivers, as discussed by the company at last weeks Intel
Developer
Forum. Microsoft "device experience" manager Kosar Jaff accurately
identified both the goal ("Applications writers dont need to know if
devices are near or far") and the impediment ("ease-of-use issues will
be overwhelming if we dont get ahead of them") that face
developers.
Having worked with a variety of remote-control
technologies, I join Jaff in emphasizing that life is different when
were applying code across constellations of devices that dont offer
users a readily reachable hardware reset button. Im inclined to give
high praise, though,
to any Microsoft manager whos willing to get up in public and say, as
Jaff did, that "the fundamental model is broken."
The Windows
Driver Framework that Jaff explored at the Intel event was
scrutinized at length during the Windows Hardware Engineering
Conference earlier this year, and I regret that I did not note it at
the time. The advantage of a longer look back at the WinHEC
presentations, though, is that it captures follow-up comments like
those in an end-of-August
memo from the self-described "single biggest critic of Microsofts
new Windows driver framework push," in which independent developer Bill
McKenzie analyzes not just the ideas but the refinement process and
concludes that hes "beginning to believe that the WDF team just gets
it."
Visions of a more modern driver model reinforce my positive
impressions from my conversation last May with Microsoft XML Web services architect
John Shewchuk, in which he talked about developing "a contractual
basis" for network interactions. One of the mechanisms that I remember
Shewchuk mentioning, toward that end, was Web Services
Reliable Messaging, a
multi-vendor standard prominently featured in a joint
IBM/Microsoft demo about a year ago: WS-RM has now reached a
critical milestone with the August
24th Committee
Draft approval of version 1.1 for likely balloting in
October. I cant improve on the concise description of this standards
scope thats part of the 1.1 announcement, so Ill just quote it here:
"WS-Reliability
supports message reliability by defining:
(1) Guaranteed message delivery, or At-Least-Once delivery semantics;
(2) Guaranteed message duplicate elimination, or At-Most-Once delivery
semantics; (3) Guaranteed message delivery and duplicate elimination,
or Exactly-Once delivery semantics; (4) Guaranteed message ordering for
delivery within a group of messages."
Rising above hardware interactions and network protocols are user
interface issues, specifically the need to free people from keyboards
and even touch-screens if theyre to interact with systems in a wider
range of environments. Speech recognition has its limits in the office,
but I believe its the critical technology for hands- and eyes-free
operation in shop-floor and automotive settings, both of which are
major growth opportunities. IBM will spur speech forward with its
open-source release, to be announced today, of speech handling software to the Apache
Software Foundation and of speech application tools to the Eclipse
Foundation.
But speaking of remote possibilities, I couldnt help but notice
that the fading-from-view Comdex is being complemented by the rise
of IT expositions elsewherespecifically, in early October, in Dubai,
where IBM will use the Gulf IT
Expo (GITEX) to place its vertical-industry initiatives before buyers who have, to put it mildly, excellent
cash flow. As Ive said before, its essential for U.S. IT
developers to get over the idea that we do the new stuff here first,
then trickle it out to the rest of the world. Its vital to develop an
international perspective on both technologies and markets if we want
to stay on the leading edges, everywhere.
