Comments from the Editor
==========================================================

Each week I get to take a few minutes to write an editorial here in the CodeGuru newsletter. Each week I have a number of different things I'd like to write about, unfortunately time doesn't always allow.

One of the things on my list has been Cω (C-omega). A couple of people have suggested Cω as a topic for me to mention. This is an experimental programming language — actually an extension to C# — that focuses on distributed asynchronous concurrency and XML manipulation. This is a combination of research projects that were formally known as polymorphic C# and Xen (and X#). For more on this, you can check out:

http://nl.internet.com/ct.html?rtr=on&s=1,1kay,1,crwg,a55z,jorm,i5r0

Another topic I've not covered, that would be interesting is Cryptyc. This is a tool for type-checking security protocols. In fact, the name stands for "Cryptographic Protocol Type Checker." For more on this interesting tool and its concepts, you can check out:

http://nl.internet.com/ct.html?rtr=on&s=1,1kay,1,gl71,7isj,jorm,i5r0

The item I've had near the top of my list the longest is Fugue. This is a tool for helping you write better .NET code. It is a "defect detection" tool. Fugue will do things such as check for fields that shouldn't be null, check for use of objects after they've been disposed, check to verify that methods are used in the proper order, and much more. Using Fugue, you record a set of rules for using a class or interface. Fugue will then verify that the rules are followed.

http://nl.internet.com/ct.html?rtr=on&s=1,1kay,1,9s99,6rwg,jorm,i5r0

This is just three of the many things I want to begin digging deeper into. There are more things that have caught my interest as well, including -

SLAM - A project for investigating the relationships between software -S-pecifications, -L-anguages, -A-nalysis, and -M-odel checking.

Behave! - A project for building tools to checking things such as deadlock freedom, invariant checking, and message-understood properties in behavior properties of asynchronous, message-passing programs.

Phoenix - A software optimization and analysis framework that is to be the basis for all future Microsoft compiler technologies.

Asta - A project investigating algorithms for detecting cloned code.

Abstract IL (ILX) - A toolkit for accessing the contents of .NET Common IL binaries . Among its features, it lets you transform the binaries into structured abstract syntax trees that can be manipulated.

AsmL - An Abstract State Machine Language. I believe you may find all of these things interesting as well.

If you've worked with any of them, then I would request that you submit an article to CodeGuru to share what you've learned with the rest of the CodeGuru community!

Until next week!

Brad!
