John Lam has published two sets of slides from the 'compiler dev lab'. Both are on the DLR runtime that is at the heart of IronPython 2, and contain interesting details about Dynamic Languages, the .NET framework, IronPython and the DLR.

IronPython in a Virtual Desktop (in a Browser!?!)
The front page of the Vista Smalltalk Website is currently showing a screenshot of IronPython running on the Virtual Desktop - inside a web-browser...
This looks like a very interesting test and development environment for IronPython on Silverlight.
The code shown illustrates using some of the core-CLR assemblies from IronPython, plus it benchmarks "a million iterations involving assignments in just over two seconds (3GHz Pentium) - this is orders of magnitude faster than traditional JavaScript".
'Orders of magnitudes faster' sounds good for web applications, but I have no idea how this compares to the upcoming alternatives...
The code isn't available yet, and I'm not sure what you'll be able to do with it (although as a testing and experimentation environment it could be awesome), but it certainly looks cool!

IronPython 2 Performance on Different Platforms
In the DLR Talk at Mix '07, Jim Hugunin claimed a 12% improvement in performance between IronPython 2 and IronPython 1.

IronPython 2 compared to IronPython 1:
Mono 1.2.4+: -32%This shows that IronPython 2 makes heavy use of some of the improvements in recent versions of the CLR runtime.

DLR Implementation: Language Trees
Jim Hugunin has posted another blog entry:
DLR Trees (Part I)
This is about how the DLR builds language trees (an AST or CST I guess?) for representing dynamic languages. These are unlike the trees that C# compilers use because they are untyped (and unbound).

This is about how the DLR builds language trees (an AST or CST I guess?) for representing dynamic languages. These are unlike the trees that C# compilers use because they are untyped (and unbound).
"The value of having dynamic languages target this tree form is that we can perform lots of optimizations in the DLR layer on behalf of the language implementations."

IronPython and "Project Jasper"
Project Jasper is a(nother) new project from Microsoft for interacting with databases:
Project Jasper is geared towards iterative and agile development. You can start interacting with the data in your database without having to create mapping files or define classes. You can build user interfaces by naming controls according to your model without worrying about binding code. Project Jasper is also extensible, allowing you to provide your own business logic and class model. Since Project Jasper is built on top of the ADO.NET Entity Framework, it supports rich queries and complex mapping.
Jasper is designed for CLR languages with late-bound facilities such as VB and IronPython. (Interesting to see new research in Microsoft that targets IronPython rather than C#.)
The project CTP includes some IronPython examples, and there are a couple of blogs that illustrate playing with Jasper from the IronPython interactive console:

Silverlight Console (and Silverlight Interactive Interpreter)
Jamie Cansdale has been exploring running Silverlight programs as console applications, rather than in the browser.
His experimenting includes the IronPython interactive shell running as a console application inside Silverlight. The reason for this experimentation is 'so that unit tests can be executed inside the CoreCLR'.

Silverlight: Dynamic Languages in the Browser
Along with the new release of IronPython comes Silverlight. Silverlight is the new name for WPF/E (Windows Presentation Foundation Evrywhere). This, amongst other things, is a sandboxed version of the CLR (the .NET runtime) for browsers. This 'core CLR' is capable of running the DLR, so you can now script browsers with IronPython.
Silverlight
The DLR comes with Silverlight 1.1 alpha, not with 1.0 beta.
There are a set of demos for using IronPython with Silverlight up on CodePlex.
http://www.codeplex.com/dynamicsilverlight
There is also a new ASP CTP (Community Technology Preview) called 'futures' which features Silverlight integration.
http://www.asp.net/downloads/futures/default.aspx?tabid=62
John Lam, one of the implementors of the DLR, along with IronRuby one of the languages that will run on top of it, has a couple of posts that link to a lot of the commentary (both positive and negative) about Silverlight and the DLR.

Uhmm... hello to me. I'm now assisting Mark (who is busy jetsetting round the world at the moment) with the IronPython URLs blog. (By the way, if you find interesting articles that we haven't linked to, then email them to one of us.)
Just to get them out of the way, here are a few articles and blog entries that I've made recently on IronPython:

A look at the Python rich comparison methods, including how IronPython is different (and better) than CPython in this respect.
