NHibernate Spatial (Part 5 - NHibernate 3.3.1+)

NHibernate Spatial is sort-of moribund, which is rather unfortunate because it's a really great project with lots of potential. Anyway, not conformed with it I decided to put the sucker onto Github to create an unofficial working version of it.

Fortunately some lads had the same idea avoiding me the extra-work. Unfortunately their projects don't have that much activity and most don't seem to really work. Anyway, in the spirit of GitHub and collaboration I decided to fork one of these to try my luck. Also, if time permits, I'll try to maintain it for future NHibernate releases.

I've forked the following project: The author already set it up nicely, making the following changes to the broken nhcontrib version:
  • Fixed compilation errors
  • Used NuGet for some references
  • Upgraded the projects from VS2008 to VS2010
So, props for suryapratap for providing a much nicer starting point. My own fork is at: where I'm going to update this library.

Going the micro-ORM way with Dapper

If you're a developer you've most certainly used stackoverflow (or any other of the stackexchange sites). It's the reference Q&A site out there and has got tons of helpful content and a really enthusiastic community.

One of my favorite things about Stackoverflow is that it's damn fast. The interface, although minimalistic, shows lots of information, refreshes everything on-the-fly and just feels snappy. It's public knowledge that Stackoverflow developers are obsessed with performance, and fortunately they've been more than happy to share their secrets with the community through some blog posts and videos.

To achieve the results you see today they've used many clever tricks and tweaks, but have also developed some in-house tools to overcome the performance limitations of existing technologies. In this post I'm going to look at their own ORM: Dapper, which is widely used in Stackoverflow and has been open-sourced on Github (link).
