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…

It seems that my previous post about FreeAndNil sparked a little controversy. Some of you jumped right on board and flat agreed with my assertion. Others took a very defensive approach. Still others, kept an “arms-length” view. Actually, the whole…

During the recent field test for RAD Studio 2010, I had a discussion with some field testers about the different mechanisms that the IDE provides for navigating through your source code.

I will discuss the capabilities of the control and consider the general problem of how to use controls designed for “plain” ASP.NET in MVC applications.
