SQL Server – error: 18456, severity: 14, state: 38 – Incorrect Login
Despite the error message this problem can be caused by something other than an Authorization failure. In fact, simply misspelling the Initial Catalog can cause this message to appear. I wish developers wouldn’t reuse error messages when the problem and solution is completely different.

Singleton tasks: A TaskFactory for the Task Parallel Library with ‘run-only-one’ semantics
about 1 year ago - No comments
When developing .NET applications there is often the need to execute some slow background process repeatedly. For example, fetching a feed from a remote site, updating a user’s last logged in time, … etc. Typically you queue actions like these onto the thread pool. But under load that becomes problematic as requests may be coming More >
Hybrid Ontology + Relational Store with SQL Server
about 1 year ago - No comments
There are many references in the literature to exposing existing SQL data sources as RDF. This is certainly one way to integrate existing databases with semantic reasoning tools but it clearly requires a lot more storage and processing than simply keeping the data in SQL and querying over it directly. So recently I began some More >
Email opt-out: Here’s a great example of how to do it right
about 1 year ago - No comments
I came across this opt-out screen today. It’s one of the best examples I’ve seen recently of an opt-out screen done right. First, they try to fix one of the key reasons people opt out of email: they are still interested but they want less email. Then they give you the option to really just More >
Cloud computing – where’s the silver lining?
about 1 year ago - No comments
I’ve seen several people propounding the cost savings of cloud computing as being of great benefit to startups. Most recently someone wrote “… cloud offers an amazing opportunity to reduce costs for startups” This simply isn’t true. It cost ~$2500 to buy a smoking hot server from Silicon Mechanics with SSD drives and under $100/month More >

Developers are sometimes confused about this issue but the fact of the matter is that you should always store Datetime values in your database in UTC and almost never in a local time zone. Canyon De Chelly, Az/NM border: One of the many places where naive use of local time will cause you problems! photo More >
ASP.NET MVC 2 and the Ambiguous Match Exception for Action methods with different signatures
about 1 year ago - 3 comments
Although you can use this technique to allow POST requests to a page avoiding a redirect this is now considered a bad practice from a usability perspective because if the user hits refresh they get the classic browser warning. You normally want to use a Post-Redirect-Get pattern: when you make a POST request, once the More >
Issues combining ASP.NET MVC and ASP.NET Web Forms in the same application
about 2 years ago - No comments
Recently I started migrating an ASP.NET WebForms project to ASP.NET MVC. Hoping to do this in phases I created a combined project that is both a webforms project and an MVC project. Routing allows some requests to go to the WebForms pages and some to go to the new MVC pages. Routing has also enabled More >
If it walks like a class, talks like a class, it probably is a class

I occasionally come across attempts to extend Enums to include additional fields. These attempts typically use Attributes and reflection to get at the extra values. I have to say I don’t like them. The most extreme example of trying to get an Enum to do something else was this article on Code Project attempting to More >
