SQLGeography in SQL Server 2012 – Polygon must start on correct position | Daniel Wertheim
published 158 days, 23 hours, 39 minutes ago posted by sedanwersedanwer 168 days, 22 hours, 10 minutes ago

I've been working with some simple spatial data lately. In one use-case, the user marks a polygon by using an iPad or iPhone in field and walks around storing points (coordinates), which after at least three points, forms an area (the first coordinates are also used as the last to close it). I’m using the built in spatial functionality in SQL Server 2012. According to SqlGeography.STIsValid and SqlGeography.IsValidDetailed, the surface was a valid polygon, but when using e.g SqlGeography.STContains and c... (more)

Customizing the minification of JavaScript in ASP.Net MVC4, allowing reserved words | Daniel Wertheim
published 174 days, 10 hours, 38 minutes ago posted by sedanwersedanwer 184 days, 4 hours, 54 minutes ago
Monday, November 26, 2012 10:49:22 PM GMT Saturday, November 17, 2012 4:33:21 AM GMT
A friend of mine just posted a question on StackOverflow, regarding having reserved member names in code, which doesn’t play well with the minifier. I opened up object explorer and started to look over the API in WebGrease and the System.Web.Optimazation framework. Just took a few minutes and put together some prototype code, that would replace the member names in the code, from “delete” to “fooDelete”. And it just doesn’t change the member names, but the usages of them as well. (more)

MongoDb for .Net folks – a quick theoretical peak what schema-less means | Daniel Wertheim

Now it’s time to have a quick peak on this whole “schema-less” thing that NoSQL products offer. We will of course focus on MongoDB when we compare a document-oriented DB against a more traditional, relational DB commonly found in RDBMS like SQL Server. (more)

This time we will have a quick look at using MongoDb as a service. The provider we will look at is MongoLab. It takes about 5 minutes to be up and running. Add a couple of minutes and you will have used Postman to do what we have done in the previous articles. Inserting and updating simple document. (more)

Having fun with ImpressJs and WebSockets, creating real-time presentations

A friend of mine showed me ImpressJs today. He was going to have notes on another screen (well actually on an iPad) and I thought it would be cool if the presentation could be synced with notes on another screen as well. Fired up Visual Studio and put together a small socket server as well as a simple java script client and created a Presenter-Attendee solution with ImpressJs and WebSockets. (more)

C#, Parallel deserialization of JSON stored in database « Daniel Wertheim

A while back ago I had to yield entities constructed by deserializing JSON stored in a database. The first solution just opened a simple single result, sequential reader against the database returning a one column result set containing JSON. This was just yield returned after deserialized to the desired entity. Trying to tweak this I turned to the task parallel library. The idea was to in a separate task, read from the datareade...

NHibernate – Custom Id-generator « Daniel Wertheim

Friday, March 11, 2011 12:04:09 PM GMT Tuesday, March 08, 2011 7:13:52 PM GMT
Recently I had a case where I needed to switch from the Identity generator to the HiLo generator in an existing project with existing data. Why? Well for one thing it gives better performance since identities brakes the ability to use batch inserts, since the generated Id needs to be returned (selected) after each insert. I didn’t want to go through and configure params for each entity, hence I created a custom implementation of an Id-generator and added some conventionbased configuration in that class ... (more)

C#, Clean up your Linq-queries and lambda expressions « Daniel Wertheim

Monday, February 07, 2011 6:10:41 PM GMT Monday, February 07, 2011 11:20:20 AM GMT
Last week something caught my eyes. How scattered business logic can become if you let your binary expressions be used “here and there” when matching entities against certain rules. Logic for a single entity, e.g Customer can be used all over your codebase. This article will show you a way to get around this and to get a central repository of rules/predicates that can be applied to entities and makes your daily unit test writing easier. I will use simple operator overloading for accomplishing this. (more)

C# – Custom datareader for SqlBulkCopy
published 921 days, 17 hours, 46 minutes ago posted by sedanwersedanwer 922 days, 2 hours, 51 minutes ago
Wednesday, November 10, 2010 3:41:01 PM GMT Wednesday, November 10, 2010 6:35:38 AM GMT
When prototyping SisoDb I used datatables under the covers when consuming the SqlBulkCopy class to insert data. This lead to that I had the source entities in memory as well as the datatables. Since the SqlBulkCopy class can work with readers I created a very simple datareader implementation over my entities instead. I gained a little performance boost and got rid of unnecessary creation of in-memory datatables. At first the API of a datareader seems kind of tedious to implement, but in the context of us...

C# – Batch identity inserts « Daniel Wertheim

I’m currently building support for identity inserts in SisoDb where I need to let the database generate the ids and then assign them to the entities. To get better performance I want to batch up the inserts and sending them in a large chunk to the Sql-server and I want to make use of parameters to be protected from sql-injection attacks. You can of course use SqlBulkCopy but it will not let you get the generated identities so that you can assign them to your entities. (more)
