I went to a get together here at TechEd last night of bloggers and “aggregators” (sounds much better than “lurker”) who are here at the show, organized by Drew Robbins who runs TechEdBloggers.net.  It was really interesting to put some faces with the names.  There were also some interesting discussions on blogs and blogging.  Many seemed comfortable with the notion I put down a while ago (http://erablog.net/filters/12142.post) of communal validation.  Someone dubbed it a “web of trust” which I think is pretty appropriate.  The question also some up, “So who plays the role of VeriSign” in this web of trust.  I think the interesting part about blogging, at least in the technical community, is that that trust seems to be based on personal relationships rather than out outside “authority”.  Unlike in the UseNet world where it’s easy to forgo personal relationships in favor of the collective, blogging seems to foster personal relationships.  That’s a big change from the general anonymity of the Web.  I’ll be interested to see where it goes from here.

Once upon a time I did the happy dance on stage (in San Francisco: “Anatomy of an eCommerce Web Site”) because I was so excited about the new BizTalk orchestration designer in BTS 2000.  What a great idea, so be able to draw business processes in Visio, then use the drawing to create code that knows how to manage a long running transactional business process.  I had been preaching the gospel of the CommerceServer pipeline as a way of separating business process from code, but BT Orchestrations was even better.

Little did I know…  Yesterday (I’m here at TechEd in Dallas) I saw a demo of BTS 2004.  Wow.  Microsoft has really made great strides in advancing the orchestration interface.  Instead of Visio, it’s now a Visual Studio.NET plugin, and the interface looks really good.  It includes hints to make sure you get everything set up corrects, and full IntelliSense to speed things along.  I was very impressed with the smoothness of the interface.  Not only that, but now you can expose your orchestration as an XML Web Service, and you can call Web Services from inside your schedule. 

I’ve always thought that BTS has gotten short shrift in the developer community.  I think it’s because it tends to be pigeon-holed as something only useful in big B2B projects.  I can think of lots of ways in which orchestration could be very useful outside the realm of B2B.  I guess part of it has to do with the pricing.  While I can think of lots of ways to use BTS in non-B2B scenarios, they aren’t really compelling enough to convince me to spend that much money.  Ah well.

The constant point-and-click of the mouse can be a real drag. One company has developed products that sense hand movements to give computer commands, creating input devices that it hopes will replace the mouse. By Katie Dean.
[Wired News]



This is a great idea, and I’d be all over it if it wasn’t quite so spendy.  I think in the long run this kind of gestural interface could really win out, since you can encode a lot of information in gestures that would be harder or take longer using other input methods.

I’m back home from New Orleans after watching my wife Vikki win a bronze medal at the US Tae Kwon Do Senior Nationals.  Woohoo!

A good time was had by all.  The competition is pretty amazing.

There's been a great deal of hullabaloo in the last week or so about blogging “ruining the Internet for everyone” and Google segregating hits from blogs into their own section (good or bad?). I realize that since I'm posting this to a blog, this sounds a bit self-serving, but here's my two cents worth:

While it's true that blogging has lowered the bar in terms of access to web publishing, the simple fact is that ever since there was an Internet, anyone who wanted two and had access to a keyboard could post whatever drivel they wanted to the web. All the blogging really adds to the mix is the fact that now you don't even have to have rudimentary knowledge of HTML (or how to save your Word doc as HTML) in order to publish yourself. While that means more volume, it doesn't really change the nature of data on the web.

The real “problem” as far as Google is concerned is that the self-referential nature of blogging upsets their ranking algorithm. This has apparently led people (like Larry Lessig) to conclude that blogging is ruining the nature of content on the web.

I would argue that there's nothing about blogging that changes the need for critical thinking when looking for information on the web. That's always been true, since there's fundamentally no concrete way to verify the validity of anything you read on any site without thinking critically about the nature of the source, how you came across it, and what references it makes to other works. If you apply that kind of filter, then the self-referencial or “incestuous” nature of blogs can be used to advantage.

For example, if I'm looking for interesting information about SOAP, XML Web Services, or how either or both relate to .NET I'd assume that Don Box (for example) is a reliable source, given that I've read his books, articles and speeches in other contexts. If he mentions something in his blog that someone else said about .NET on their blog, I would assume a high degree of certainty that the reference is relevant and useful. Then, when I follow that link, I'll find more links to other blogs that contain relevant and useful information. The tendency is for all those cross links to start repeating themselves, and to establish a COMMUNITY wherein one can assume a high degree of relevant information. All that's needed to validate the COMMUNITY as a whole is a few references from sources that are externally trusted.

In the long run, I think that kind of “incestuousness” can be used to validate, rather than discount large bodies of interesting, useful, and otherwise unattainable information that we wouldn't have access to otherwise.

That's a fairly lengthy rant for me, but I had to get that off my chest. I hate to see pundits discounting a body of information just because it's posted casually and not in academic journals.

I'll be giving a presentation on "XML on Large Power Transformers and Substation Batteries" at the Applied XML Developers Conference 2003 West, on July 10th and 11th in Beaverton, OR. Register now at www.sellsbrothers.com/conference.
It looks like there are going to be some really interesting sessions, and tickets reportedly go fast, so sign up now.
I'm really interested in hearing "SOAP, it wasn't Simple, we didn't Access Objects and its not really a Protocol", and "A Steady and Pragmatic Approach to Dynamic XML Security". Cool stuff.

Sean Campbell and Scott Swigart have some pretty strong words about Access vs. MSDE. This is a subject I hadn't spent much time thinking about until pretty recently. I had the opportunity to give some presentations at an Access user's group conference (PAUG)

Being pretty much a died in the wool SQL Server enthusiast (bigot?) I hadn't realized how many people out there are writing useful, complex Access applications that are solving real business problems today. I also hadn't realized that most of them don't want to have anything to do with MSDE. As Sean and Scott put forth, it's just too much work. It's too hard to users to install, not easy to get configured properly, etc. Also, the SQL that MSDE/SQL Server supports is different enough from Access SQL to be not just a minor bit of tweaking in many cases but a full fledged porting activity, Upsizing Wizard or no.

So up until fairly recently, I would have been just as dismissive as Don Box was of their Access rant, but now I'm not so sure. I still haven't changed my feelings about the nature of Access (I still would use MSDE myself) but I have a much more profound understanding of the nature of the Access developer community, and how threatening rather than enabling MSDE looks to them.

Scott has posted a very insightful article into the nature of the CLR as it relates to the underlying Windows platform, and how that's different from the way the Java VM works.
Keep up the good work Scott!

It's amazing how little things have changed on the web when you really look at the details. Lots of things that seemed like a good idea to a few people 5-6 years ago now seem like a good idea to a whole bunch of people. Scott Hanselman was musing about what ever happened to PointCast, which was quite the technology back in it's day. In response Don Box supplied a little piece of CDF, the PointCast equivalent used by IE 4.0. Sure looks a lot like RSS to me, without all the namespaces :)

It seems like every time I come across something in the framework documentation that says something along the lines of "this works just fine unless" my application is firmly in the "unless" category :)

There is a new security setting in 1.1 that has to do with serializing objects over remoting which is much more restrictive than the 1.0 framework was. I recompiled my app against 1.1, fixed all the compile time bugs, tracked down all the dependencies, and then the real fun began: finding the runtime bugs.

It turns out that there is a new setting on the remoting formatters that won't deserialize your object by default unless they fall into a certain category of "safe" objects. Mine apparently don't, although going over the list on gotdotnet I don't see how my objects don't fall into the category of "low". Anyway, for whatever reason they don't, so I have to prompt the remoting formatters to use "Full" deserialization. (Low vs. Full???) Then everything works hunky-dory. I wish that the list of conditions was a little more exhausitve. The only things listed as for sure causing a need for "full" support are sending an ObjRef as a parameter, implementing ISponsor, or being an object inserted in the remoting pipeline by IContributeEnvoySink. I tried this with two completely different parts of my application, neither of which meet those criteria, and still had to use "full" support. Hmmmm.

Live and learn I guess.
