Using LINQ for Computational Genomics

I’ve been playing around a bit lately with computational genomics (I’m doing a project for my parallel computation class). I wanted to write some simple algorithms that operate on potentially large amounts of DNA data without using a ton of RAM. For example,

More on generic variance

In my entry on generic variance in the CLR , I said that you can’t convert a List<String> to a List<Object>, or even an IEnumerable<String> to IEnumerable<Object>. I should point out however that the real-world scenarios where

Linq and the cost of additional language complexity

Uwe Keim posted a thought provoking comment in response to my entry about Linq . Here is an excerpt: I do see the benefits, but I also have a big déjà vû: The C#-language seems to go the C++-way, where I, even after 10 years of programming, don't know

Comparison of a simple select statement in DLinq (C# 3.0) vs. ADO.Net

Six months ago I posted a comparison of a simple select statement in C-omega vs. ADO.Net which some people found very exciting. Now that Linq has been officially unveiled, I figured I should update my comparison using C# 3.0 and DLinq . Although Linq

Interested in C-omega? LINQ finally announced!

Ever since I started planning for my users-group talk (and wrote this blog entry ) about data access with C-omega, I've been dying to tell everyone about the plans to add similar functionality to C#. For those of you at my talk, you'll remember this video

Comega talk

On Thursday I gave a .NET users group talk on Comega to somewhere around 100 .NET developers. Overall I think it went pretty well. I was nervous at first, but once I got into talking about the cool stuff I like I forgot about the pressure and had a good

Comparison of a simple select statement in C-omega vs. ADO.Net

In a couple weeks, I'm doing a talk at a .NET users group in Ontario about Cω . Cω is a cool research language from Microsoft Research that extends C# with direct support for data access (SQL and XML) and concurrency abstractions. I’ve been planning on

Generic type parameter variance in the CLR

When people start using C# generics for the first time, they are sometimes surprised that they can’t convert between related generic instances. For example, since you can convert a string to an object , shouldn’t you also be able to convert a List <string>
