A couple of weeks ago, I wrote What Is Homomorphic Encryption, and Why Should I Care? In that post, I promised to share my C# implementation of the algorithm from Craig Gentry’s CACM article. Before I can do that, though, I need to explain some of…

What Is Homomorphic Encryption?
“Homomorphic” is an adjective which describes a property of an encryption scheme. That property, in simple terms, is the ability to perform computations on the ciphertext without decrypting it first. Because this tends to sound either baffling or miraculous the first time you hear it, let’s begin…

DataSnap 2010 (DS2010) extended the list of server method parameter types with the full suite of JSON types.
It is now possible to pass a TJSONObject instance for example from a client process to a server as input or output parameter and…

This is the fourth post in a series on using jqGrid with ASP.NET MVC. Today, we’re going to examine search and formatting results. I will implement a search feature and fix the problem with formatting date columns which I observed in the last post.

Having introduced jqGrid and written LINQ extension methods to make supplying data to the grid easy, we’re now ready to put together a demo application. The solution I’m going to build demonstrates sorting and paging. In a future post, I will…

Mere hours after I posted the first in a planned series of posts on using jqGrid in ASP.NET MVC applications, Phil Haack, a rather-more-widely-read-ASP.NET-MVC-blogger, wrote a long post on, er, exactly the same thing. Who, me, bitter? Naahhh… 🙂
But it turns out that we’re using the grid in a different way, and I think the difference is important. So rather than…
