BriForum 2008 Aftermath

Now that six weeks have passed since BriForum 2008 in Chicago, I’m finally getting a chance to blog about it.  Certainly it has been covered by a number of angles by now and perhaps there is nothing to add.  I’m willing to try to add something new.

First of all, I was very impressed with the quality of the conference and the type of people attending.  It really didn’t feel like a typical event thanks in large part to not being driven by a large corporation.  Brian has his own touch with the help of his small company of workers.  The premises at Navy Pier were more than adequate and even though there were more than 400 people attending it never felt rushed or too confined.  The capacity of the rooms was well matched and it is obvious that in general BriForum has learned from past experiences.

The speakers were very well informed and had excellent presentation skills.  I enjoyed getting a chance to meet them and even ask a few questions.  To me, they were real people that wanted to share their technical knowledge.  It was excellent to finally meeting so many of them in those three days.

It was interesting to witness so much interest in VDI.  Having just worked on XenDesktop for the last couple of years it was good to hear feedback from the industry.  The idea was that it is becoming time for VDI-based technologies but there are still certain things that need to change before it receives a more widespread acceptance.  The most obvious need is to make the multimedia support more compelling.  The goal of VDI should be to provide as best an experience as possible.  Assuming that VDI can work with LAN bandwidth and latency, it should be possible to create a better desktop over the wire.  This concept was explored many times from many angles during the conference and it is obvious to the industry that without a serious push for better end-user video/audio, it just is not going to be as widely used.

It was unexpected to hear that the attendees thought that XenApp and XenDesktop should be combined into a single product.  From what I’ve heard, this actually made sense from a customer point of view.  Administrators don’t want to have to worry about duplicating effort and having the separation between XenApp and XenDesktop only encourages more work.  The original assumption was that XenDesktop would be targeted at a different market space but now it is obvious that we are largely dealing with the same customers.

Another remark I heard a few times is that it would be wise to invest more effort into XenApp.  Brian’s reaction about XenApp 5.0 was largely about what big things it does not have.  In other words, XenApp is seen as a strategic product but there is not a lot of proof that it is still being greatly expanded.  This was later rationalized in another session as XenApp being a mature product and therefore not in need of major changes.

Overall I thought the sessions were very well produced and also fair.  It’s nice to see a level playing field with players that are willing to confess errors.  Bias is much more obvious when the sessions are hosted for the sake of a large corporate entity.

There was no large animosity towards any company.  I had heard some concerns from Citrix employees that attendees might be biased against Citrix or even the speakers but I saw no evidence of this.  I concluded that any criticism was based on real experiences and was fairly localized to specific topics.  In fact the event seemed mostly positive towards the companies involved.

After having experienced BriForum first hand, I would highly suggest technical professionals in this field attend in 2009.  It is worth much more than the price and even though I came from across the world to attend I am more than happy to consider attending again.

Thanks Brian!

Technology Faith

I just returned from America a few days ago.  There was a BriForum conference in Chicago on June 16 to 18 and I was lucky enough to attend.  It’s worthy of describing the conference but I’ll save that until after I write up a summary first.

I didn’t have time to do any blogging during this work/holiday trip so this is the first post in around six weeks.  It seemed strange at first to stop but now it seems just as strange to start up again.

The topic of this post is what I would call technology faith.  The title probably gives it away but for those of you that aren’t already several paragraphs ahead, I’ll explain.

We, as a civilization, have built many inventions and some of these inventions have become embedded in our society as daily tools.  Things like the automobile, television, and the elevator are used without even any thought.  It is just expected that these things will work.  We have faith that these items will do what they are meant to do and will not break down.

The newer the technology, the more likely it will be faulty.  We still have faith that it will work well but we are often tolerate of its failings given the benefits and its young age.

Enter the era of computers and suddenly the opportunity for failure increases exponentially.  Not only can things fail from a hardware perspective, but also from bad code as well.  Add to this the expected universal addition of components and software and you have something that would be hard to test and guarantee.

This certainly is not new news.  However, during this last trip I came to realize some things that are new to me.

People are still treating computers like they are a new technology.  The truth is that core of the computer architecture dates from the 1940s.  It was heavily popularized in the business world in the 1950s and even more boosted by the introduction of PCs in the 1970s.  The point is that they have been around for quite some time.  Yet, people are still acting like it is a technology that is brand new.

Looking back, technologies that we use in our daily lives were also at one point considered unstable or difficult to use.  The original automobiles were so complicated that it took quite a bit of training to operate one.  It took nearly 20 years to build a successful popular automobile.  In general, it takes about 10 to 20 years to stabilize and popularize a new technology.

So why hasn’t this been true with computers?

The simple answer is that computers are always obsoleting previous generations.  The new generations actually inherit a core base but perform so much better that the original weaknesses are often overlooked.  In other words, there is no common technology base since it keeps on getting thrown out.  The real twist comes from the fact that each new generation makes it that much more complicated than the previous.  The guarantees that it the new platform will be more fragile than the previous.

I had a bizarre thought about how computers have so much further to go.  For example, if the human brain was modeled like a computer, any fault would cause instant paralysis.  Worse than this, most unexpected situations would likely trigger an error.  Being that the world is full of unexpected situations, this quickly leads to a very unhappy experience.

The point of this is that computers should function more like a brain in its ability to function regardless of the environment.  Obviously the brain has limits as well but the ability to function and not to freeze is a key difference.  Implicitly there is existing technology that would already allow for more tolerance of unknown events but the real flaw seems to be the fully digital nature of computer processing.  What I mean is that most decisions are made based on true/false analysis and this means that vague data does not lead to a maybe.  If the code accesses memory that causes a fatal exception (like in a driver), it seems a bit extreme to take down the whole machine.   I understand the reason why and based on the current thinking it is only way to go (except for exception handling) but the point is that the computer is so intolerant of this simply because it has no recourse for handling this kind of problem.  Its kind of like saying something bad happened and because the computer had no idea of what to do, it just gave up.  A brain wouldn’t give up that easy.  It prefers life and either finds a solution or a way to not answer the annoying question.

At this point it would be wiser to not be so faithful in computer technology.  It does seem like a good time to make it more accountable for its bad behavior.  I suspect that either people don’t know it could be better or they have just become used to the weaknesses.  Personally I’m getting tired of errors with no cures that stop me from getting something done.  Its much better to be intolerant and expect change.

It seems like the first step is to say “we aren’t going to take it anymore”.  The next step is for hardware and software companies to evolve the model so that the platform becomes much more reliable and usable.  There is still too much technology loving going on in the industry and it would be much wiser to address the old weaknesses and provide a truly usable platform.  It does seem that Apple is much more interested in this approach than others.
