On Wednesday I started doing some contract work at Corillian Corp.  Not only am I doing some really interesting work, but I'm working with my friend Scott Hanselman.  I shared an office with him for a couple of years at STEP Technolgy, and I'd forgotten how much fun it is.  Scott is one of the quickest thinking guys I've ever known, not to mention an actual standup comic :).  It turns out that I know a bunch of people at Corillian, including some people I worked with at Intel once upon a time, and the three best project managers I've ever had the pleasure to work with.  Should be a good time.

I finally got around to moving this blog to dasBlog.  Now I'll have a lot more control over how things look, as well as features, etc.  Right now it's using one of the default templates, so there will probably be some cosmetic changes as I get time to mess with templates.  All of the old permalinks should still work, although the RSS has moved to http://www.cauldwell.net/patrick/blog/SyndicationService.asmx/GetRss

In one of his posts a while back, Scott mentioned that he was using Mozilla Firebird, so I decided to check it out.  Wow.  It completely rocks.  Page rendering is WAY faster than in IE, and I have yet to see any of the major rendering problems that I recall from previous experiments with Mozilla/Netscrape.  I’ve only seen a couple of minor issues regarding table layout (and the fact that Windows Update won’t load at all).  I set it as my default browser, and haven’t had any reason to resort back to IE (except for Windows Update).  

Possibly the best part is there extension architecture.  There are extensions for all kinds of things, including a Google bar, an Amazon browser, and a great download manager that handles multiple concurrent downloads without popping up extra windows.   

There are only two things which still vex me… 1) I can’t for the life of me figure out any way of replicating IE’s “never reuse browser windows” feature.  I’m so used to it that I keep clobbering stuff I’m not done with by clicking on links.  2) I miss my context menu for “Subscribe in NewsGator” when right clicking on links.  (I think I may be able to come up with a solution, just haven’t had time yet.)

Scott posted a great rant on what it means to be a GenX geek (I’m one too, although I’ve at least seen a punch card at the Smithsonian J ).  I was inspired to check out the geek test, and I only scored a 45%.  I was sure that those SCA questions would put me over the top.  Sigh.  I guess I came to it late.  I’ve always been a geek, but I didn’t really come to grips with that fact (or dedicate my life to it) until I was in college.  

And just in case anyone was wondering, I’m an INTJ, which didn’t really come as a surprise to me.

Clemens Vasters posted a great article on what’s really behind a Service Oriented Architecture from the implementation standpoint.  He makes some very astute points about why schemas are important for expressing service contracts, and what the implications of SOA are on implementing scalable solutions.  Having wrestled a bit with this myself, I agree with his conclusion that old-school OOD is not the way to approach this particular problem.  Also, with regards to the stateful vs. stateless issue, I really like his take:

Ruling out that state is implicitly shared between services (in memory or on disk) is a direct consequence from this and also serves the scalability purpose, because it further eliminates co-location assumptions about services and enables clustering. Note that this isn’t about “stateless” or “stateful”. Everything is stateful while it runs.

I’ve been a big fan of XMLSpy for a long time.  It’s one the best XML tools out there, and I’d have to say the very best schema editor.  Now with their new version 2004, you can integrate XMLSpy directly into VS.NET, and use all the functionality of XMLSpy without having to leave everyone’s favorite development environment.  Very cool stuff. I much prefer the schema editor in XMLSpy to the database-centric one that ships with VS.NET, so it’s nice not to have to launch yet another app to get at it.

I love appropriate applications of technology, and I just came across a really cool one.  Our public transit system here in Portland (Hillsboro) OR now has up to the minute bus tracking information available for cell phones (trimet.org/wap) and wirelessly connected PDAs (trimet.org/pda).  You put in what route and which stop you are at, and it will tell you when the next bus is coming.  How cool is that?!  As someone who both has a WAP phone and commutes to work on public transit (since I can’t afford one of the new 2004 Prius), I’m pretty excited.  This is possibly even better than WAP/PDA accessible movie times, which was formerly my favorite application of wireless technology.  Since they are pretty static, I actually get my movie times through AvantGo on my PocketPC (a ViewSonic v37).

If you haven’t already, check out the PDC episode of Red vs. Blue.  Talk about an appropriate use of technology…

Werner Vogels posted a great article on what Web Services are and aren’t, and why they represent Service Oriented Architecture, and not a Distributed Object Architecture.  Don’t let the name SOAP fool you.

Just finished struggling through yet another Windows Forms issue that had us completely baffled.  Writing multi-threaded WinForms applications brings up some very interesting challenges, and involves learning a bunch of new stuff, some of which is not at all obvious.  See my previous posts on InvokeRequired for a good example. There end up being some really interesting consequences of the boundary between the CLR only world, and the underlying implementation where windows have to deal with message pumps.  While WinForms insulates us from the real underlying PeekMessage calls, they are still there, and at some point the rubber has to meet the road, so to speak.  The problem I just had to deal with is way to complicated to even summarize here, but the core of the problem was that if I call Thread.Sleep on short intervals in a loop with calls to Application.DoEvents in between, the GUI doesn’t update correctly, but if I call Form.ShowDialog then it does.  WinForms knows something about message pumping that I don’t, which doesn’t really come as a surprise. 

Some days I think that this is way harder than MFC was, but on other days (like today) I realize that the real difference is that WinForms frees us to hurt ourselves in new and different ways that were too hard to achieve before.  I can only think that’s a step in the right direction. J
