singleton pattern

So how cool is that. I was running through one of the new MSDN enterprise application blocks in the debugger (IMHO, the best way to get to know a piece of code). And I was stepping my way through and what do I see but an URL to a blog entry explaining the singleton pattern, and why it was utilized in this particular situation. Some of the best sample code I’ve ever seen…

./sqlexpress

I love diving into new technology. So much to learn, so many cools things. A whole lot of reading going on. So I’ve installed Microsoft Visual Studio 2005 (VS2005) and am wanting to work through a number of the samples. In particular, samples related to database / n-tier development. And VS2005 has a lot of new features for databases and database development. But when your learning you need to start somewhere.  And I decided to start with the Microsoft MSDN Enterprise Library June 2005.  This is a library of source applications for you to take a part and learn from. So I download the files, and begin to set things up.  This is great, so to get the database samples running I need an instance of SQL Server.  And fortunately, one comes with VS2005, it’s known as SQL EXPRESS or MSDE (by its previous encarnation).  One problem it has no GUI. So how do you create databases, tables, etc. Well you could do it from within VS2005. But I’m a database guy at heart so I want my query window. Again fortunately, there is Express Manager a free download.  If you used the default VS2005 default setup you need to logon to a server instance of SQL EXPRESS. This one got me, I was thinking “localhost” would work, nope! I ended up discovering that the instance you logon to is.\sqlexpress (that’s dot slash sqlexpress) there you have it. So much to learn, so little time… fun, fun, fun…

Open Courseware

Evidence toward a trend. Over the last three years I have developed the though that curriculum should be developed once and used by everyone. At this time, on the planet earth, there must be a huge duplication of course material and curriculum. I wonder how many 1st year spanish courses have been developed, and how many more will be developed. Or what about 1st year calculus. The duplication of course material and effort in creating and delivering this material must be staggering. What a waste of Masters and PhD educated peoples time. Why not just develop the course material once and have it shared around the globe? It would all become a part of the creative commons. It could all be a part of a SCORM type standard which uses a UDDI type directory service for the discovery of the course material required by either student or teacher. We can see the beginnings of this with the opencourseware site of MIT. This isn’t a matter of if a global repository of courseware will be available, but when it will be available…
